The answer is <span>D. $661.55
</span>
A = P * eᵃˣ
A - the future value
P - the principal
a - the rate
x - the period of time

We know:
A = ?
P = $500
a = 4% = 4%/100% = 0.04
x = 7

A = P * eᵃˣ
A = 500 * e⁰.⁰⁴*⁷
A = 661.55

Solve the four problems below. Which of the following problems can be solved by finding ? 3 divided by 1/2
Anastasy [175]

Answer:

(a)=6\\(b)=1\ \frac {1}{2}\\(c)=1\ \frac {1}{2}\\d=6

Step-by-step explanation:

(a)

3 ft long when divided into half ft each will be

3ft ÷1/2 ft

We change the ÷ to × then the second part is reciprocated hence

3ft÷1/2= 3ft×2/1=6 pieces

(b)

The question requires us to get the differences. Initially, Phil makes 3 quarts of soup but the family takes only half of the original quantity to mean Phil remains with the other half.

Therefore, half of 3 is 3×1/2=3/2= 1.5 or 1 1/2

(c)

Hiding 3 pounds of gold into two equal sections means 3 is divided by 2

3÷2=1.5 or 1 1/2

(d)

If half, 0.5 represent 3 cups then full quantity represent x

0.5=3 cups

1=x

By cross multiplication

1*3/0.5=6

Need done and Hurry
kicyunya [14]

Answer:

see explanation

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

To calculate m use the slope formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (5, - 2) and (x₂, y₂ ) = (3, 6)

m = \frac{6+2}{3-5}= \frac{8}{-2} = - 4

Using (a, b) = (5, - 2), then

y + 2 = - 4(x - 5) ← third on list

-----------------------------------------------

Using (a, b) = (3, 6), then

y - 6 = -4(x - 3)
