The value will be $371.39.
What is compound interest?Compound interest is the interest you earn on interest. This can be illustrated by using basic math: if you have $100 and it earns 5% interest each year, you'll have $105 at the end of the first year. At the end of the second year, you'll have $110.25.
The formula to calculate the compound amount after t years is given by :-
A =P [tex](1 + R)^{T}[/tex]
where the interest rate is r and P represents the principal amount.
Given: $150 is the principal sum.
Interest is charged at a rate of 12%/0.12
A = 150 will be the amount compounded after 8 years.
A = 150 [tex]( 1 + 12 )^{8}[/tex]
A =371.3944
A = $371.39
Hence, the value of $150 after eight years if you earn 12 percent interest per year would be $371.39.
option a. is right

The Pythagorean Theorem, given by the formula a² + b² = c², relates the
three sides of a right triangle. Solve the formula for the positive value of b in
terms of a and c.
Answer:
Below
Step-by-step explanation:
a^2 + b^2 = c^2 subtract a^2 from both sides
b^2 = c^2 - a^2
take the positive sqrt of both sides ( since you can't have a negative length)
b = sqrt (c^2 - a^2)
if the equation x^2 + 16x + c = 0 has only one real solution, the value of c must equal
If the equation x² + 16x + c = 0 has only one real solution, the value of c is equal to 64.
Discriminant:The quadratic formula includes the discriminant, which comes after the square root. The discriminant of a quadratic equation is important because it indicates the quantity and kind of solutions.
The formula for the Discriminant of a Quadratic Equation ax²+bx +c = 0 is given by
Discriminant Δ = b² - 4acHere we have
x² + 16x + c = 0 equation has only one real solution
Compare given equation with ax²+ bx + c = 0
=> a = 1, and b = 16
As we know when an equation has only one real solution
then its Discriminant will be equal to zero
=> b² - 4ac = 0
By the above values,
=> 16² - 4(1)c = 0
=> 256 - 4c = 0
=> 4c = 256
=> c = 256/4
=> c = 64
Therefore,
If the equation x² + 16x + c = 0 has only one real solution, the value of c is equal to 64.

Verizon charges $0.50 per minute plus a monthly base fee. In October, Noah used 200 minutes and his bill was $100
The monthly base fee of the situation is $0
How to determine the monthly base fee of the situationFrom the question, we have the following parameters that can be used in our computation:
Charges per minute = $0.50 per minute
Number of minutes = 200 minutes
Total charges = $100
The above parameters mean that
Total charges = Monthly Base fee + Charges per minute x Number of minute
Substitute the known values in the above equation, so, we have the following representation
Monthly base fee + 0.50 * 200 = 100
This gives
Monthly base fee + 100 = 100
Subtract 100 from both sides
Monthly base fee = 0
Hence, the monthly base fee is $0

Why do you need to state restrictions on the variable when dividing rational expressions?.
It is important to state the restrictions before simplifying rational expressions because the simplified expression may be defined for restrictions of the original.
What is rational expressions?
The ratio of two polynomials is a rational expression. F can be expressed in the form p/q, where p and q are polynomials, if f is a rational expression.
Fractional terms are seen in rational expressions. We include constraints because with some x values, the equation may become undefined. Undefined inquiries are hypothetical or ideal. The seven expressions for undefined words are (∞-∞),∞^∞, N/0, 0⁰, 1^∞, ∞/∞ and 0×∞ respectively. N/0 is the most typical constraint on rational expressions. Any number divided by 0 is therefore undefined. For instance, if you substitute 0 for x in the case of the function f(x) = 6/x2, the outcome is 6/0, which is undefined. If you graphed this function, you would see a break at x=0.

Given,
Base length, l = 6 km
Height, h = 10 km
dl/dt = -9 km/min
dh/dt = 12 km/min
Surface area of a prism, A = 2 × (lw + lh + wh)
For a square prism,
Length, l = width, w = 6km
A = 2 × (l² + lh + lh)

dA/dt = 2 × (2I × dI/dt + 0 × dh/dt + 2 × 2h × dl/dt + 2l × dh/dt)
dA/dt = 2 × (2l × dl/dt + 0 + 2 × 2h × dl/dt + 2l × dh/dt)

The equation of the straight line is 2y + 21x = 10. The correct option is (D).
How to represent a straight line on a graph?To represent a straight line on a graph consider two points namely x and y intercepts of the line. To find x-intercept put y = 0 and for y-intercept put x = 0. Then draw a line passing through these two points.
The given points are (-4, 47) and (2, -16) respectively.
The equation of the straight line passing through them can be written as,
(y - 47)/(x - (-4)) = (-16 - 47)/(2 - (-4))
=> (y - 47)/(x + 4) = -63/6
=> (y - 47)/(x + 4) = -21/2
=> 2(y - 47) = -21(x + 4)
=> 2y - 94 = -21x - 84
=> 2y + 21x = -84 + 94
=> 2y + 21x = 10
Hence, the standard form of the straight line passing through given points is 2y + 21x = 10.

DJ was going to meet his family at the beach in NC. He looked on a map and saw that the beach he was going to was 800 km from his house and he knew he would average 110 km/hr on the highway. How long is it going to take him to get to the beach?
On average, it is going to take DJ 7.27 hours to get to the beach.
What is the average?Average refers to the quotient when a numerator is divided by a denominator.
In this situation, the average refers to the time, which is the quotient of the distance and speed.
The total distance going to the beach from his family = 800 km
The average speed = 110 km/hr
The time to cover the distance of 800 km at 110 km/hr = 7.27 hours (800/110).
