mel-nik [20]3 years ago
3 0

Answer:

No. The answer would be n=5

Step-by-step explanation:

You have to subtract the 2 from both sides to cancel it out on the left side. so you would be doing 7-2, not 7+2

Solve 4x- c = k for x. <br>A. x = k-c/4<br>B. x = 4(k-c)<br>C. x- k+c/4<br>D. x = 4 (k+c)​
Harrizon [31]

Answer:

A

Step-by-step explanation:

You would first add c to the side that k is on and then divide k+c by 4 because it is 4x which means they are being multiplied together so you have to divide to get them apart.

Select all that apply. Select the formulas that give the amount P in the account after the first period.
Lisa [10]

Options :

a.) P=1.005Po

b.) P=1.02Po

c.) P=Po(0.02/4)

d.) P=Po(4.02/4)

e.) P=Po(1+ 0.02/4)

Answer:

a.) P=1.005Po

d.) e.) P=Po(1+ 0.02/4)

Step-by-step explanation:

From the compound interest formula:

P = P0(1 + r/n)^t

Rate = 2% = 2/100 = 0.02

n = Number of compounding times per period, quarterly ; n = (12 /3) months

P = P0(1 + 0.02/4)^1

P = p0(1 + 0.02/4)

Simplifying further :

P = P0(1 + 0.005)

P = p0(1.005)

Determine el radio vector del punto medio del segmento que se forma al unir los puntos (-8, 7) y (6, 3).
tiny-mole [99]

Answer:

The radius vector is (-8, 7) and (-1 , 5).

Step-by-step explanation:

Determine the radius vector of the midpoint of the segment that is formed by joining the points (-8, 7) and (6, 3).

The end points are (- 8, 7) and (6, 3) .

The mid point is given by

x = \frac{x' + x''}{2}\\\\y = \frac{y' +y''}{2}\\\\x =\frac{- 8 + 6}{2}=-1\\\\y = \frac{7+3}{2} = 5

So, the radius vector is (-8, 7) and (-1 , 5).

Answer:

This answer involves finding the circumference of the circle which is basically the length of the entire perimeter of the garden

Step-by-step explanation:

Circumference = 2 * pi * radius

2 * pi * 9 ft = 56 ft
