Answer:

r = 3 ft

Step-by-step explanation:

Area = 9π

So, πr²=9π where r is the radius

so, r²=9

or, r=√9

or, r=3, since r can't be negative

There are 12 inches in 1 foot and 5,280 feet in 1 mile. Jada ran 34 miles.

zvonat [6]

For this case we must convert 34 miles to feet and inches.

34 miles to feet:

$34 miles * \frac {5280} {1} * \frac {feet} {miles} = 179,520 feet$

Jada runs 179,520 feet

34 miles to inches:

$34 miles * \frac {5280} {1} * \frac {feet} {miles} * \frac {12} {1} * \frac {inches} {foot} = 2,154,240 inches$

Jada runs 2,154,240 inches

Answer:

Jada ran 179,520 feet

Jada ran 2,154,240 inches

Let f(t) ANSWER: 1+ = t² - 1 t+3 Find f'(1)

Luda [366]

Answer:

f(1) = 3

Step-by-step explanation:

f(t) = t² - 1t + 3

we want to find f(1)

all we have to do is replace the t's with 1 and evaluate

f(1) = (1)² - 1(1) + 3

evaluate exponent 1² = 1

f(1) = 1 - 1(1) + 3

multiply

f(1) = 1 - 1 + 3

subtract

f(1) = 3

Find the 16th term for the sequence a (n)=3-2n.

Scilla [17]

In the expression given, the "n" is referring to a certain term, in this case, it would be the 16th term. So in order to find the 16th term, all you have to do is substitute n as 16 in the expression, so the answer is $a(n)=3-2(16)=3-32=-29$ . So the 16th term of the sequence is -29.
