Answer:

Step-by-step explanation:

This is a geometric sequence.

a = first term = 1

Common ratio = r = second term ÷ first term

                        = (3/5)÷ 1 = 3/5

t_{n}=ar^{n-1}\\\\t_{8}=1*(\dfrac{3}{5})^{7}\\\\= \dfrac{3^{7}}{5^{7}}\\\\\\= \dfrac{2187}{78125}

Car: 18.4% Other: 4.9%

Step-by-step explanation:

Glenn family yearly total expenses are

\$8,600+\$4,800+\$5,400+\$2,400+\$7,000+\$1,800=\$30,000

Other expenses are $7,000.

The payments for the new car are: $375.00 per month and the insurance for the new car $85.00 per month, in total, $460 per month. Yearly expenses for car are

\$460\cdot 12=\$5,520

Now, the expenses for the following two categories are

Car - $5,520

Other - $7,000 - $5,520 = $1,480

Percentage:

Car:

\dfrac{5,520}{30,000}\cdot 100\%=18.4\%

Other

\dfrac{1,480}{30,000}\cdot 100\%\approx 4.93\%

Answer:

Step-by-step explanation:

The distance between the vertex and the directrix is 4 units, that means that p = 4 in the equation

(y-k)^2=4p(x-h) and h and k are the coordinates of the vertex. Filling in:

(y+4)^2=4(4)(x+2) which simplifies to

(y+4)^2=16(x+2) choice C
