Answer:

b = 20 when a = 8.

Step-by-step explanation:

For this problem, we will simply plug the value of a=8 into the given equation for b, to find the value of b.

b = [ (a)^2 / 4 ] + 4

b = [ (8)^2 / 4 ] + 4

b = [ 64 / 4 ] + 4

b = [ 16 ] + 4

b = 20

Hence, when the value of a=8, then the value of b=20.

Cheers.

Answer:

Step-by-step explanation:

a1 = 6

a2 = 10

a3 = 14

The next member of the sequence is 4 more than the current sequence. Therefore d = 4

a1 = 6

d = 4

n = 13

an = a1 + (n - 1)*d

an = 6 + (n - 1)*4

a_13 = 6 + 12*4

a_13 = 6 + 48

a_13 = 54

What is the rate of change of the volume of the cylinder at that instance (in cubic kilometers per second)?

Kay [80]

Answer:

hello your question is incomplete attached below is the complete question

answer : -2400 π

Step-by-step explanation:

dr/dt = -12 km/s

h = 2.5 km

r = 40 km at some instant

hence the rate of change of Volume of cylinder at that instance

= dv / dt = $d(\pi r^h ) / dt$

= $\pi h\frac{d(r^2)}{dt}$ = $-\pi h *2r *dr/dt$

hence ; dv / dt = -2400 π

Mr. Scruggs got some money for his birthday. He spent 1/5 of it on dog treats. Then, he divided the remainder equally among his

Mariulka [41]

Answer:

a. $\frac{4a}{15}$

b. $225

Step-by-step explanation:

Let Mr. Scruggs got money for his birthday be 'a'

He spent $\frac{1}{5}$ of it on dog treats = a × $\frac{1}{5}$

= $\frac{1}{5}a$

remainder amount would be = a - $\frac{1}{5}a$

= $\frac{4a}{5}$

Then he divided the remainder money equally among 3 favorite charities.

$\frac{\frac{4a}{5}}{3}$

= $\frac{4a}{15}$

a. Each charity receive $\frac{4a}{15}$

b. If he donated $60 to each charity.

$\frac{4a}{15}=60$

$a=\frac{15\times 60}{4}$

a = $225

Mr. Scruggs received $225 for his birthday.
