Given directed line segment AB determine point X on the graph such that X partions the segment A to B in a ratio of 1:4 and given its coordinates A(5,1) and b(-5,4)
(NEED THIS ASAP!!)
Answer:
The coordinates of point X that divides the line in 1:4 are: (3,8/5)
Step-by-step explanation:
When a point divides a line with coordinates (x1,y1) and (x2,y2) in ratio m:n,
the coordinates of point are given by:
\((x,y) = (\frac{mx_2+nx_1}{m+n} , \frac{my_2+ny_1}{m+n})\)
Given points are:
(x1,y1) = (5,1)
(x2,y2) = (-5,4)
Putting the values in the formula
\(X(x,y) = (\frac{(1)(-5)+(4)(5)}{1+4} , \frac{(1)(4)+(4)(1)}{1+4})\\= (\frac{-5+20}{5}, \frac{4+4}{5})\\=(\frac{15}{5}, \frac{8}{5})\\=(3,\frac{8}{5})\)
Hence,
The coordinates of point X that divides the line in 1:4 are: (3,8/5)

Answer:
\((f + g)(4) = 191\)
Step-by-step explanation:
Given
\(f(x) = 5x^2 - 5x + 15\)
\(g(x) = 6x^2 + 7x - 8\)
Required
\((f + g)(4)\)
First, calculate \((f + g)(x)\)
This is calculated as:
\((f + g)(x) = f(x) + g(x)\)
So, we have:
\((f + g)(x) = 5x^2 - 5x + 15+6x^2 + 7x - 8\)
Collect like terms
\((f + g)(x) = 5x^2 +6x^2 - 5x+ 7x + 15 - 8\)
\((f + g)(x) = 11x^2 + 2x + 7\)
Substitute 4 for x
\((f + g)(4) = 11*4^2 + 2*4 + 7\)
\((f + g)(4) = 191\)

We can simplify cosec(t)tant(t) to sec(t). A trigonometric function is a mathematical function that relates the angles of a triangle to the ratios of its sides.
The most common trigonometric functions are sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc).
To simplify the expression cosec(t)tant(t), we need to use the trigonometric identity:
cosec(t) = 1/sin(t)
tant(t) = sin(t)/cos(t)
Substituting these expressions into the original expression, we get:
cosec(t)tant(t) = (1/sin(t))(sin(t)/cos(t))
The sin(t) term in the numerator and denominator cancel out, leaving:
cosec(t)tant(t) = 1/cos(t)
Recalling the definition of secant, sec(t) = 1/cos(t), we can express the simplified expression as:
cosec(t)tant(t) = 1/sec(t)
Therefore, we can simplify cosec(t)tant(t) to sec(t).

Step-by-step explanation:
We have been given a 5-sided regular polygon inside a circumcircle. A circumcircle is a circle that passes through all the vertices of a given polygon. Therefore, the radius of the circumcircle is also the radius of the polygon.
To find the radius of a regular polygon given its side length, we can use this formula:
\(\boxed{\begin{minipage}{6 cm}\underline{Radius of a regular polygon}\\\\$r=\dfrac{s}{2\sin\left(\dfrac{180^{\circ}}{n}\right)}$\\\\\\where:\\\phantom{ww}$\bullet$ $r$ is the radius.\\ \phantom{ww}$\bullet$ $s$ is the side length.\\\phantom{ww}$\bullet$ $n$ is the number of sides.\\\end{minipage}}\)
Substitute the given side length, s = 8 cm, and the number of sides of the polygon, n = 5, into the radius formula to find an expression for the radius of the polygon (and circumcircle):
\(\begin{aligned}\implies r&=\dfrac{8}{2\sin\left(\dfrac{180^{\circ}}{5}\right)}\\\\ &=\dfrac{4}{\sin\left(36^{\circ}\right)}\\\\ \end{aligned}\)
The formulas for the area of a regular polygon and the area of a circle given their radii are:
\(\boxed{\begin{minipage}{6 cm}\underline{Area of a regular polygon}\\\\$A=\dfrac{nr^2\sin\left(\dfrac{360^{\circ}}{n}\right)}{2}$\\\\\\where:\\\phantom{ww}$\bullet$ $A$ is the area.\\\phantom{ww}$\bullet$ $r$ is the radius.\\ \phantom{ww}$\bullet$ $n$ is the number of sides.\\\end{minipage}}\)
\(\boxed{\begin{minipage}{6 cm}\underline{Area of a circle}\\\\$A=\pi r^2$\\\\where:\\\phantom{ww}$\bullet$ $A$ is the area.\\\phantom{ww}$\bullet$ $r$ is the radius.\\\end{minipage}}\)
Therefore, the area of the regular pentagon is:
\(\begin{aligned}\textsf{Area of polygon}&=\dfrac{5 \cdot \left(\dfrac{4}{\sin\left(36^{\circ}\right)}\right)^2\sin\left(\dfrac{360^{\circ}}{5}\right)}{2}\\\\&=\dfrac{5 \cdot \left(\dfrac{4}{\sin\left(36^{\circ}\right)}\right)^2\sin\left(72^{\circ}\right)}{2}\\\\&=\dfrac{\dfrac{80\sin\left(72^{\circ}\right)}{\sin^2\left(36^{\circ}\right)}}{2}\\\\&=\dfrac{40\sin\left(72^{\circ}\right)}{\sin^2\left(36^{\circ}\right)}\\\\&=110.110553...\; \sf cm^2\end{aligned}\)
The area of the circumcircle is:
\(\begin{aligned}\textsf{Area of circumcircle}&=\pi \left(\dfrac{4}{\sin\left(36^{\circ}\right)}\right)^2\\\\&=\dfrac{16\pi}{\sin^2\left(36^{\circ}\right)}\\\\&=145.489779...\; \sf cm^2\end{aligned}\)
The area of the shaded area is the area of the circumcircle less the area of the regular pentagon plus the area of the small central circle.
The area of the unshaded area is the area of the regular pentagon less the area of the small central circle.
Given the shaded area is equal to the unshaded area:
\(\begin{aligned}\textsf{Shaded area}&=\textsf{Unshaded area}\\\\\sf Area_{circumcircle}-Area_{polygon}+Area_{circle}&=\sf Area_{polygon}-Area_{circle}\\\\\sf 2\cdot Area_{circle}&=\sf 2\cdot Area_{polygon}-Area_{circumcircle}\\\\2\pi r^2&=2 \cdot \dfrac{40\sin\left(72^{\circ}\right)}{\sin^2\left(36^{\circ}\right)}-\dfrac{16\pi}{\sin^2\left(36^{\circ}\right)}\\\\2\pi r^2&=\dfrac{80\sin\left(72^{\circ}\right)}{\sin^2\left(36^{\circ}\right)}-\dfrac{16\pi}{\sin^2\left(36^{\circ}\right)}\\\\\end{aligned}\)
\(\begin{aligned}2\pi r^2&=\dfrac{80\sin\left(72^{\circ}\right)-16\pi}{\sin^2\left(36^{\circ}\right)}\\\\r^2&=\dfrac{40\sin\left(72^{\circ}\right)-8\pi}{\pi \sin^2\left(36^{\circ}\right)}\\\\r&=\sqrt{\dfrac{40\sin\left(72^{\circ}\right)-8\pi}{\pi \sin^2\left(36^{\circ}\right)}}\\\\r&=3.44874763...\sf cm\end{aligned}\)
Therefore, the radius of the small circle is 3.45 cm (3 s.f.).
Lorenzo and his friends are planning a trip to the Spring Shot trampoline park. The employee Lorenzo spoke to on the phone said the total cost for all 4 of them would be $68. This includes a $2 fee added to each entrance ticket to cover the cost of a pair of grip socks. What is the cost of an entrance ticket?
Answer:
15 smukeroos
Step-by-step explanation:
The cost of an entrance ticket on the trip to Spring Shot trampoline park is equal to $ \(16\frac{1}{2}\).
What do you mean by algebraic expressions ?
Algebraic expression is an equation which consists of variables and the arithmetic operations such as division , multiplication , etc.
It is given that the total cost of trip for Lorenzo and his friends is $68.
Let's assume the cost of the entrance ticket be x.
The cost of entrance ticket for all of them = 4x
The fee added to entrance ticket is $2.
So , the algebraic expression can be written as :
2 + 4x = 68
reordering the like terms :
4x = 68 - 2
4x = 66
Dividing by 2 on both sides :
2x = 33
or
x = \(\frac{33}{2}\)
or
x = \(16\frac{1}{2}\)
Therefore , the cost of an entrance ticket on the trip to Spring Shot trampoline park is equal to $ \(16\frac{1}{2}\).

The results of a common standardized test used in psychology research is designed so that the population mean is 155 and the standard deviation is 50. A subject earns a score of 155. How many standard deviations from the mean is the value 155
Answer:
The value 155 is zero standard deviations from the [population] mean, because \( \\ x = \mu\), and therefore \( \\ z = 0\).
Step-by-step explanation:
The key concept we need to manage here is the z-scores (or standardized values), and we can obtain a z-score using the next formula:
\( \\ z = \frac{x - \mu}{\sigma}\) [1]
Where
z is the z-score.x is the raw score: an observation from the normally distributed data that we want standardize using [1].\( \\ \mu\) is the population mean.\( \\ \sigma\) is the population standard deviation.Carefully looking at [1], we can interpret it as the distance from the mean of a raw value in standard deviations units. When the z-score is negative indicates that the raw score, x, is below the population mean, \( \\ \mu\). Conversely, a positive z-score is telling us that x is above the population mean. A z-score is also fundamental when determining probabilities using the standard normal distribution.
For example, think about a z-score = 1. In this case, the raw score is, after being standardized using [1], one standard deviation above from the population mean. A z-score = -1 is also one standard deviation from the mean but below it.
These standardized values have always the same probability in the standard normal distribution, and this is the advantage of using it for calculating probabilities for normally distributed data.
A subject earns a score of 155. How many standard deviations from the mean is the value 155?
From the question, we know that:
x = 155.\( \\ \mu = 155\).\( \\ \sigma = 50\).Having into account all the previous information, we can say that the raw score, x = 155, is zero standard deviations units from the mean. The subject earned a score that equals the population mean. Then, using [1]:
\( \\ z = \frac{x - \mu}{\sigma}\)
\( \\ z = \frac{155 - 155}{50}\)
\( \\ z = \frac{0}{50}\)
\( \\ z = 0\)
As we say before, the z-score "tells us" the distance from the population mean, and in this case this value equals zero:
\( \\ x = \mu\)
Therefore
\( \\ z = 0\)
So, the value 155 is zero standard deviations from the [population] mean.

Two friends are renting a property with a monthly rent of $975.00. The total square footage is 1,225 square feet, the first bedroom is 150 square feet, and the second bedroom is 130 square feet. Determine how much the friend with the smaller bedroom will pay for rent if they split the cost based on the square footage of each bedroom. (2 points)
$479.50
$481.35
$495.50
$501.35
Answer:
(a) $479.50
Step-by-step explanation:
You want to know how much the friend with the smaller bedroom will pay for rent if they split the $975 cost based on the square footage of each bedroom. The two bedrooms in the 1225 square foot property are 130 and 150 square feet.
SplitApparently, the cost of the non-bedroom area is to be split evenly. That common area is ...
1225 ft² -(150 +130) ft² = 945 ft²
Then the proportion due from the occupant of the smaller bedroom is ...
(945/2 +130)/1225 = 241/490 ≈ 0.49184
RentThat fraction of the rent is ...
0.49184 · $975 = $479.54
The nearest answer choice is $479.50.
__
Additional comment
If we were to assume the split is based only on bedroom size, then the rent paid for the 130 ft² space would be (13/28)($975) ≈ $452.68. This would be equivalent to splitting the rent for the common area in the same proportion as for the bedrooms.
We note that half the rent is $487.50, a number less than either of the last two answer choices. Those can be rejected for that reason. (The smaller bedroom is expected to pay less than half of the rent.)
A tablet that regularly sells for $330 was
on sale for 15% off. If Jeremiah paid
$302.94 total including tax, what is the N
sales tax rate?
Answer:
The sales tax rate is 7.96%.
Step-by-step explanation:
To determine the sales tax rate, we need to first calculate the amount of the discount on the tablet by multiplying the regular price by the discount percentage:
Discount = Regular price * Discount percentage
Discount = $330 * 15%
Discount = $49.50
Next, we can calculate the total price of the tablet before taxes by subtracting the discount from the regular price:
Total price before taxes = Regular price - Discount
Total price before taxes = $330 - $49.50
Total price before taxes = $280.50
Finally, we can calculate the sales tax rate by dividing the total amount of taxes paid by the total price of the tablet before taxes and multiplying by 100% to express the result as a percentage:
Sales tax rate = (Total amount of taxes paid / Total price before taxes) * 100%
Sales tax rate = ($302.94 - $280.50) / $280.50 * 100%
Sales tax rate = $22.44 / $280.50 * 100%
Sales tax rate = 7.96%
Therefore, the sales tax rate is 7.96%.
