Answer:

12

Step-by-step explanation:

B x H x 1/2 = area of a triangle

we can break this figure into 4 different triangles and since we have the length of the chords (dotted lines) in the diamond we can easily solve it.

half of QS is 2 and half of PR is 3

2 x 3 = 6

6 / 2 = 3

since there are four triangles multiply 3 by 4 (3 x 4)

and you get 12.

The value of y - x based on the mentioned two equations is -29/5 or 219/5.

We have equation 1: x² + 4y = 8 and equation 2: x + 5y = 7

Rewriting equation 2 in terms of x

x = 7 - 5y : equation 3

Substitute the value of x from equation 3 into equation 1

(7 - 5y)² + 4y = 8

Expand the bracket

49 + 25y² - 70y + 4y = 8

Rewriting the equation

25y² - 66y + 41 = 0

y = 1/5 or 41/5.

Keep the value of y in equation 2 to find the value of x for solving expression y - x.

If value of y is 1/5

x = 7 - 5(1/5)

x = 7 - 1

x = 6

If value of y is 41/5

x = 7 - 5(41/5)

x = 7 - 41

x = - 34

The possible values of y - x will be :

If y is 1/5 and x is 6, then

y - x = 1/5 - 6

y - x = -29/5

If y is 41/5 and x is -34, then

y - x = 41/5 - (-34)

y - x = 219/5

Hence, the value of y - x can be -29/5 or 219/5.

A. To save for her payout annuity with an ordinary annuity set up thirty years before her retirement, Holly Krech must make a monthly payment of $175.97.

B. If she sets up the ordinary annuity twenty years before her retirement, Holly Krech must make a monthly payment of $432.00.

To calculate the monthly payment for an ordinary annuity set up thirty years before retirement, we can use the formula for the present value of an ordinary annuity. Given the deposit amount of $218,437.048 and the total amount received from the annuity of $432,000, and solving for the monthly payment, we find that Holly must make a monthly payment of $175.97.

For an ordinary annuity set up twenty years before retirement, we use the same formula for present value. With the deposit amount and total amount received unchanged, we solve for the monthly payment, which comes out to be $432.00.

It's important to note that the monthly payment increases when the annuity is set up closer to the retirement date. This is due to the shorter time period available for saving, resulting in a higher required contribution to reach the desired payout amount.

The point where the equation of the line touch the circle is (2.166, 3.083).

and

The equation of a circle with center (h, k) and radius r is:

(x - h)^2 + (y - k)^2 = r^2

So the equation of the circle with center (0, 2) and radius 5 is:

x^2 + (y - 2)^2 = 25

We can solve for the intersection of the circle and the line y = 0.5x + 2 by substituting y = 0.5x + 2 into the equation of the circle:

x^2 + (0.5x)^2 + 2x + 2^2 - 25 = 0

Simplifying and solving for x:

1.25x^2 + 2x - 9 = 0

Using the quadratic formula, we get:

x = (-2 ± √(2^2 - 41.25(-9))) / (2*1.25)

x = (-2 ± √(104)) / 2.5

x ≈ -6.166 or x ≈ 2.166

Since we are looking for a point in the first quadrant, we take the positive value of x:

x ≈ 2.166

Now we can use the equation of the line to find the corresponding y-coordinate:

y = 0.5x + 2

y ≈ 3.083

Therefore, the point where the line y = 0.5x + 2 intersects the circle with radius 5 and center (0, 2) in the first quadrant is approximately (2.166, 3.083).

Step-by-step explanation:

The equation in vertex form is \(y=a(x+2)^2+5\).

We can use the point \((1,32)\) to solve for \(a\).

\(32=a(1+2)^2+5 \\ \\ 27=9a \\ \\ a=3 \\ \\ \\ \therefore y=3(x+2)^2 + 5 \\ \\ =3(x^2+4x+4)+5 \\ \\ =3x^2+12x+12+5 \\ \\ =3x^2+12x+17\)

Answer:

f(x) = 0

px^2 + qx - 4p = 0

abc-Formula: x = (-b ± √(b^2 - 4·a·c))/(2·a)

x = (-q ± √(q^2 - 4·p·(-4p)))/(2·p)

x = (-q ± √(q^2 + 4^2·p^2))/(2·p)

Because q^2 + 4^2·p^2 > 0 there are two roots.

The vertex form of the equation is y = (x - 3)² - 4, which corresponds to option OD.

To convert the given equation from standard form to vertex form, we need to complete the square.

The vertex form of a parabola's equation is y = a(x-h)² + k, where (h, k) represents the vertex of the parabola.

Given equation: y = x² - 6x + 14

Move the constant term to the right side:

y - 14 = x² - 6x

Complete the square by adding and subtracting the square of half the coefficient of x:

y - 14 + 9 = x² - 6x + 9 - 9

Group the terms and factor the quadratic:

(y - 5) = (x² - 6x + 9) - 9

Rewrite the quadratic as a perfect square:

(y - 5) = (x - 3)² - 9

Simplify the equation:

y - 5 = (x - 3)² - 9

Move the constant term to the right side:

y = (x - 3)² - 9 + 5

Combine the constants:

y = (x - 3)² - 4

There are no values of $b$ for which the base-$b$-representation of $2013$ ends in the digit $3$. For a number to end in the digit $3$ in base-$b$ representation, it must be congruent to $3$ modulo $b$.

We can rewrite $2013$ as $2 \cdot 10^3 + 0 \cdot 10^2 + 1 \cdot 10^1 + 3 \cdot 10^0$. Now, if $2013$ is congruent to $3$ modulo $b$, it means that $2 \cdot 10^3 + 0 \cdot 10^2 + 1 \cdot 10^1 + 3 \cdot 10^0$ is also congruent to $3$ modulo $b$.

Simplifying the expression, we have $2000 + 0 + 10 + 3$. Since the base-$b$-representation is formed by multiplying each digit by the corresponding power of $b$, we can rewrite the expression as $2 \cdot b^3 + 1 \cdot b^1 + 3 \cdot b^0$. We can now observe that the constant term $3 \cdot b^0$ will always be congruent to $3$ modulo $b$. However, the other terms $2 \cdot b^3$ and $1 \cdot b^1$ will not be congruent to $3$ modulo $b$ for any positive value of $b$. Therefore, the base-$b$-representation of $2013$ cannot end in the digit $3$ for any value of $b$.

Hence, there are no values of $b$ for which the base-$b$-representation of $2013$ ends in the digit $3$.

The best inequality that represents the possible price of each DVD is P≤12.50, found by dividing the total cost of 4 DVDs ($50) by 4.

Let's assume the price of each DVD to be P dollars.

Then the total cost of 4 DVDs would be 4P dollars.

Since Nikki had money left on the gift card after the purchase, the cost of the DVDs must be less than or equal to $50, the value of the gift card.

So we have the inequality:

4P ≤ 50

Dividing both sides by 4, we get:

hope this helps :)

the main answer is that the mean value of the activity time is 21.67. This is calculated using the formula (optimistic + 4 * most likely + pessimistic) / 6.

To find the mean value of the activity time, we can use the three estimates provided: optimistic, most likely, and pessimistic time.

1. The optimistic time is the shortest possible time for completing the activity, which is 11 units.
2. The most likely time is the time that is most likely to be taken to complete the activity, which is 21 units.
3. The pessimistic time is the longest possible time for completing the activity, which is 35 units.

To calculate the mean value, we can use the following formula:
Mean value = (optimistic + 4 * most likely + pessimistic) / 6

Substituting the given values, we get:
Mean value = (11 + 4 * 21 + 35) / 6

Calculating the numerator first:
11 + 4 * 21 + 35 = 11 + 84 + 35 = 130

Now, we can calculate the mean value:
Mean value = 130 / 6

Dividing 130 by 6, we get:
Mean value = 21.67 (rounded to two decimal places)

Therefore, the mean value of the activity time is 21.67.

The result x(t) = 13t is a solution of the differential equation dx/dt = kx where k = 1/t

In this question, we are given a differential equation dx/dt = kx.

This equation is called a first-order homogeneous linear differential equation.

This means that the highest derivative that appears in the equation is the first derivative, and there are no nonlinear terms.

The coefficient k is a constant that represents the rate at which the quantity x(t) changes with respect to time t.

Given the differential equation

dx/dt = kx

And,

x(t) = 13t is a solution

We need to find k.

In order to find the value of k, we differentiate the given solution with respect to time t and equate it to the given differential equation.

dx/dt = d/dt (13t)

= 13

Substituting the value of x and dx/dt in the differential equation, we get:

13 = k (13t)

⇒ k = 1/t

Therefore, k = 1/t.

Substituting the value of k in the given differential equation, we get:

dx/dt = (1/t) x .............................(1)

Now, let’s verify whether x(t) = 13t is a solution of the differential equation (1).

LHS of (1) = d/dt (13t)

= 13

RHS of (1) = (1/t) (13t)

= 13

Therefore, x(t) = 13t is a solution of the differential equation dx/dt = kx where k = 1/t

To find a particular solution of the differential equation, we are given that x(t) = 13t is a solution.

The penalty on Casey's nonqualified distributions is a) $0.

The penalty on Casey's nonqualified distributions is $74. Casey turned age 65 on May, 2020 and during the year she received distributions from her health savings account (HSA) totaling $728.96. She paid for electrolysis on March 3, 2020. Casey paid $44.87 to her ENT doctor on June 4, 2020, and $315 to her chiropractor in July and August.

Non-qualified distributions from a health savings account (HSA) before the age of 65 are subject to a 20% penalty. This penalty is imposed in addition to the usual taxes on non-qualified distributions. However, once an account holder reaches the age of 65, the penalty no longer applies, but normal taxes are still imposed.

In this case, Casey was 65 years of age in May 2020. Thus, she is not subject to a penalty on any of her HSA distributions. She received $728.96 in HSA distributions over the year. The penalty on her nonqualified distributions is $0.

Therefore, the correct option is a. $0.

The triangle PQR is an equilateral triangle

From the question, we have the following parameters that can be used in our computation:

PQ=QR.

m/P = (2x - 26) and m/R= (x+17)

When two sides of a triangle are congruent, then the triangle is an isosceles triangle

Using the above as a guide, we have the following:

2x - 26 = x + 17 --- base angles of an isosceles triangle

So, we have

x = 43

This gives

m/P = 2 * 43 - 26 = 60

m/R= 43 + 17 = 60

By theorem angle opposite to equal sides are equal so,

We can say that angle P = angle R = X

Therefore by angle sum  property of the triangle,

angle P + angle Q + angle R = 180°

X +(2x - 26)+ (2x - 26) = 180°
