Answer:

1150in^3 is close

Step-by-step explanation:

We'll be using the formula for volume of a sphere.

We need the radius - but it's just half the diameter, so r = d/2 = 13in / 2 = 6.5in

V = \frac{4}{3}\pi r^2\\~\\V = \frac{4}{3}\pi \cdot (6.5in)^3 = \frac{4}{3}\pi \cdot 274.625in^3 = \pi \cdot 366.16666...~ in^3 \approx 1150.34650999 in^3\\

if f(1) = -5 and f(n) = f(n-1) +7, find the first four terms and the common difference of the sequence
Alex_Xolod [135]

Answer:

- 5, 2, 9, 16 and d = + 7

Step-by-step explanation:

to obtain the first four terms substitute n = 2, 3, 4 into the recursive formula

f(1) = - 5 ← given

f(2) = f(1) + 7 = - 5 + 7 = 2

f(3) = f(2) + 7 = 2 + 7 = 9

f(4) = f(3) + 7 = 9 + 7 = 16

common difference d = 16 - 9 = 9 - 2 = 2 - (- 5) = 7

PLEASE HELP FAST!! Lake Alice is filled with alligators and turtles. The number of turtles is 16 less than 3 times the number of
san4es73 [151]

Answer:

72 alligators, 128 turtles

Step-by-step explanation:

When you put the words into the form of an equation, with a being alligators, you get

3a-16=200

So you have to do 'letters left numbers right'. This gives you

3a=216

Now you have to divide. 216 divided by 3 equals 72. So there are 72 alligators. 200 minus 72 equals 128, so there are 128 turtles
