Answer:

$130.06

Step-by-step explanation:

Interest is calculated as shown;

I = A - P

A is the amount

P is the principal

Given

Principal = $316

Rate R = 9% = 0.09

Time t = 4yrs

Substiutte and get Amount A

A =P(1+r)^n

A = 316 (1+0.09)^4

A = 316(1.09)^4

A = 316(1.4116)

A = 446.06

Interest = 446.06 - 316

Interest = 130.06

Hence the interest is $130.06

What is the value of 2 over 3 to the power of 0 to the power of -3

Schach [20]

Answer:

$((\frac{2}{3})^0)^{-3}=1$

Step-by-step explanation:

We need to find the value of $((\frac{2}{3})^0)^{-3}$

Solving:

We know, $(a^b)^n = a^{b*n}$

$((\frac{2}{3})^{0*-3})$

$(\frac{2}{3})^0$

a^0 = 1

so,

$(\frac{2}{3})^0=1$

So, the value of $((\frac{2}{3})^0)^{-3}=1$

How fast is the apple traveling when the kinetic energy is 32 joules?

Daniel [21]

Answer

The apple is traveling at 8 meters per second

Explanation

We have the equation that relates the kinetic energy with the velocty:

$K=\frac{v^2}{2}$

Then, to find thevelocity when the apple has 32, we replace K = 32 j:

$\begin{gathered} 32=\frac{v^2}{2} \\ 32\cdot2=v^2 \\ 64=v^2 \\ v=\sqrt{64}=8 \\ \end{gathered}$

Thus, the speed of the apple is 8meter per second

A trapezoid has an area of 60 square inches. The height of the trapezoid is 5 inches. What is the length of the longer base if t

Vinil7 [7]

Answer:

Step-by-step explanation:

Remark

Let the shorter base = x

Let the longer base = 3x

h = 5

Area = 60

Formula

Area = (b1 + b2)*h /2

Solution

60 = (x + 3x)*5 / 2 Multiply both sides by 2

2*60 = (x + 3x)*5 Combine like terms

120 = 4x *5

120 = 20x Divide by 20

120/20 = x

x = 6

Therefore the two bases are

x = 6

3x = 18
