Ms. Brooks put $1200 in a3retirement account that offers8% interest compounded annually.Ms. Brooks makes no additionaldeposits or withdrawals. How muchinterest will Ms. Brooks have earnedat the end of 2 years?
Answers
Solution
- We are required to find the compound interest on a $1200 invested in a retirement account if it is compounded annually at 8% interest for 2 years.
- In order to find the compounded interest, we use the formula:
\(\begin{gathered} A-P=I \\ \text{where,} \\ A=\text{ Amount compounded after n years} \\ P=\text{ Principal or Initial Amount} \\ I=\text{ Compounded interest} \end{gathered}\)- But before we can use the above formula, we need to first calculate the Amount compounded. This can be gotten using the formula below:
\(\begin{gathered} A=P(1+\frac{r}{n})^{nt} \\ \\ \text{where,} \\ n=\text{ The number of times the interest in compounded per year} \\ t=\text{ Number of years} \end{gathered}\)- Thus, we can proceed to solve the question by first finding the Amount compounded over the 2 years and then going on to calculate the compound interest.
Compounded Amount:
We can find the compounded amount as follows:
\(\begin{gathered} A=P(1+\frac{r}{n})^{nt} \\ \\ A=1200(1+\frac{8}{100\times1})^{2\times1} \\ \\ A=1200(1+\frac{8}{100})^2 \\ \\ A=1399.68 \end{gathered}\)-
Compounded interest
\(\begin{gathered} I=A-P \\ I=1399.68-1200 \\ \\ \therefore I=199.68 \end{gathered}\)Final Answer
The interest is $199.68

Midpoint formula:
\($C(x, y) = \left(\frac{x_A + x_B}{2}, \frac{y_A + y_B}{2}\right)$\)
Now, substitute the coordinates of points A and B:
\($C(x, y) = \left(\frac{24 + 3}{2}, \frac{7 + 4}{2}\right)$\)
Simplify:
\($C(x, y) = \left(\frac{27}{2}, \frac{11}{2}\right)$\)
So, point C has coordinates \((\frac{27}{2}, \frac{11}{2}).\)
Now we can find the value of \(2x - 4y:\)
\($2x - 4y = 2\left(\frac{27}{2}\right) - 4\left(\frac{11}{2}\right) = 27 - 22 = 5$\)

To reflect a point across the line y=3, we find the point that is the same distance from y=3 as the original point, but on the opposite side of the line. In this case, the original point is B(−4,−6), which is 9 units below y=3. The image point will be 9 units above y=3, so it will have a y-coordinate of 3+9=12.

cos(α + β) = (4√5 - 6)/25
sin(α - β) = (-6√5 + 8)/25
tan(α - β) = (-9√5 + 45)/4
We have,
Recall the trigonometric identities:
sin(a + b) = sin(a)cos(b) + cos(a)sin(b)
cos(a + b) = cos(a)cos(b) - sin(a)sin(b)
sin(a - b) = sin(a)cos(b) - cos(a)sin(b)
cos(a - b) = cos(a)cos(b) + sin(a)sin(b)
tan(a - b) = (tan(a) - tan(b))/(1 + tan(a)tan(b))
Using these identities, we can find the exact values of the expressions given.
(a) Sin (α + β)
sin(α + β) = sin(α)cos(β) + cos(α)sin(β)
= (√5/5)(-3/5) + (2/5)(-4/5) (using the values given for sin and cos)
= -6√5/25 - 8/25
= (-6√5 - 8)/25
(b) Cos (α + β)
cos(α + β) = cos(α)cos(β) - sin(α)sin(β)
= (2/5)(-3/5) - (√5/5)(-4/5) (using the values given for sin and cos)
= -6/25 + 4√5/25
= (4√5 - 6)/25
(c) Sin (α - β)
sin(α - β) = sin(α)cos(β) - cos(α)sin(β)
= (√5/5)(-3/5) - (2/5)(-4/5) (using the values given for sin and cos)
= -6√5/25 + 8/25
= (-6√5 + 8)/25
(d) tan (α - β)
tan(α - β) = (tan(α) - tan(β))/(1 + tan(α)tan(β))
= ((√5/5) - (-4/5))/(1 + (√5/5)(-4/5)) (using the values given for sin and cos)
= (9√5/5)/(1 - 4/5√5)
= (-9√5 + 45)/4
Therefore,
The exact values are:
sin(α + β) = (-6√5 - 8)/25
cos(α + β) = (4√5 - 6)/25

AE=2a + 10
ED=x + 3
CD=4
Enter you answer In the box
Answers
The given values into the equation AE = 2a + 10. Therefore, The value of AE is 3 - x.
To find the value of AE, we can substitute the given values into the equation AE = 2a + 10.
Given:
AB = 10
AE = 2a + 10
ED = x + 3
CD = 4
Since AB is a segment on the line, it can be divided into AE and ED. Therefore, AB = AE + ED.
We know that AB = 10 and CD = 4. So, if we subtract CD from AB, we get AE + ED = 10 - 4.
AE + ED = 6.
Now, we can substitute the value of ED, which is x + 3, into the equation: AE + x + 3 = 6.
To find the value of AE, we need to isolate it on one side of the equation. Let's subtract x and 3 from both sides:
AE = 6 - x - 3.
Simplifying further, we get;
AE = 3 - x.
Therefore, the value of AE is 3 - x.

find a triple integral for the volume in cartesian coordinates of the region in the first octant bounded below by the paraboloid x2 + y2 = z and bounded above by the plane z = 2x
Answers
The volume of the region in the first octant bounded below by the paraboloid x^2 + y^2 = z and bounded above by the plane z = 2x is 16/15 cubic units.
The region in the first octant bounded below by the paraboloid x^2 + y^2 = z and bounded above by the plane z = 2x can be expressed as
0 ≤ x ≤ √z
0 ≤ y ≤ √z - x^2
0 ≤ z ≤ 2x
To find the volume of this region, we need to integrate the constant function 1 over the region, i.e.
V = ∫∫∫ dV
where dV = dx dy dz.
The limits of integration for each variable are given above. Thus, the triple integral becomes
V = ∫₀²x ∫₀√z-x² ∫₀²x 1 dz dy dx
Integrating with respect to z first, we get
V = ∫₀²x ∫₀√z-x² 2x dy dx
= ∫₀²x 2x(√z-x²) dx
Substituting z = x^2 + y^2, we get
V = ∫₀²x 2x(√(x^2 + y^2) - x^2) dy dx
Using a trigonometric substitution y = x tanθ, we get
V = ∫₀^(π/4) ∫₀^(2cosθ) 2x(√(x^2 + x^2 tan^2θ) - x^2) dx dθ
= ∫₀^(π/4) ∫₀^(2cosθ) 2x(√(1 + tan^2θ) - x^2) dx dθ
= ∫₀^(π/4) [x^2(1 + tan^2θ)^(3/2) - (1/3)x^4] from x = 0 to x = 2cosθ dθ
= ∫₀^(π/4) [8cos^3θ(1 + tan^2θ)^(3/2) - (32/3)cos^5θ] dθ
Simplifying using trigonometric identities, we get
V = (32/3) ∫₀^(π/4) cos^5θ dθ
This integral can be evaluated using integration by substitution or by using the reduction formula for cos^nθ. Either way, we get
V = (32/15)[cos^4(π/4) - cos^4(0)]
= (32/15)(1/2 - 1)
= (16/15) cubic units

A group of students were asked to find a 3rd side length for a triangle that has two sides that are
already 10 inches and 14 inches long. Which of the following could be the length of the third piece?
Answers
Using the Pythagorean Theorem, the length of the third piece of the triangle is d) 17.2 inches.
What is the Pythagorean Theorem?According to the Pythagoras Theorem, in a right-angled triangle, the square of the hypotenuse side, c, equals the sum of the squares of the other two sides.
The opposite side is a while the adjacent is the base, b.
We can find the hypotenuse when we have the lengths of the two sides.
Then the Pythagoras can be stated in the form of a²+b² = c² or c² = a²+b².
Finally, the hypotenuse, c = √a²+b²
Let one side, a = 10 inches
Let another side, b = 14 inches
Let the third side, c = ?
c² = a² + b²
c² = 10² + 14²
c² = 100 + 196
c² = 296
c = √296
c = 17.2 inches
Thus, assuming that the third piece of the triangle is the hypothenuse, its length is d) 17.2 inches.

Answers
Roland has built a circuit, and is using a device called an
ammeter to measure how quickly electrical current is flowing
through the circuit. He calculates that the current should be
0.180 amps, but he measures the current as 0.173 amps. What
is Roland's percent error?
Answers
Roland's percent error is approximately 3.889%.
This means that his measured value differs from the actual value by 3.889% or 0.03889 in decimal form.
The positive sign indicates that Roland's measured value is slightly lower than the actual value.
To calculate Roland's percent error, we can use the formula:
Percent Error = (|Measured Value - Actual Value| / Actual Value) \(\times\) 100
Given that Roland measured a current of 0.173 amps while expecting a current of 0.180 amps, we can substitute these values into the formula:
Percent Error = (|0.173 - 0.180| / 0.180) \(\times\) 100
Simplifying the expression within the absolute value:
Percent Error = (|-0.007| / 0.180) \(\times\) 100
Since the absolute value of -0.007 is 0.007, we have:
Percent Error = (0.007 / 0.180) \(\times\) 100
Calculating the division:
Percent Error = 0.03889 \(\times\) 100
Percent Error = 3.889%.

Answers
To reach her home in half an hour, she needs to double her speed twice, which is equivalent to a 200% increase in speed. Therefore, the correct answer is 200%.
What is speed?Speed is a measure of how quickly an object or person moves from one point to another. It is usually expressed in terms of distance traveled over time, for example, miles per hour or kilometers per hour.
To calculate this, we need to find the time taken for her to reach her home if her speed is doubled.
If her initial speed is 40 km/hr, then by doubling her speed, she will be travelling at a speed of 80 km/hr.
By travelling at this speed, she can reach her home in half an hour i.e. 30 minutes.
Therefore, the time taken to reach her destination by doubling her speed is 30 minutes.
The time taken to reach her destination while travelling at her initial speed is 2 hours.
To calculate the percentage increase in speed, we have to find the ratio of the time taken to reach her destination when the speed is doubled to the time taken to reach her destination when the speed is not doubled.
Therefore, the percentage increase in speed
= (30/120) x 100
= 25%.
Since she needs to double her speed to reach her home in half an hour, the percentage increase in speed required is 100%.
To reach her home in half an hour, she needs to double her speed twice, which is equivalent to a 200% increase in speed.
Therefore, the correct answer is 200%.
