Answers

Answer 1

Answer:

153.8 = 3.14r^2

Divide each side by 3.14 to get r alone.

48.9 = r^2

Take the square root of each side to isolate r.

r = 6.999

r= 7

Answer 2

Answer:

r=12.27

153.8-3.14=150.66

150.66 square root is 12.27

What are the zeros of the function f(x) =(x^2 - 3x - 10)(x + 4)
!!Please help!!!

Answers

f(x) = (x² - 3x - 10)(x + 4) becomes (x - 5)(x + 2)(x + 4) when completely factored. Now set each binomial equal to zero.

x - 5 = 0
x = 5

x + 2 = 0
x = - 2

x + 4 = 0
x = - 4

Your zeros are at x = - 4, - 2, and 5. Or at (- 4, 0), (- 2, 0), and (5, 0).

Rita's graduation picnic will cost $3 for every attendee. At most how many attendees can there be if Rita only budgets a total of $87 dollars for her graduation picnic?

Answers

To figure out how many attendees Rita can have at her picnic, we must divide the total amount that she has in her budget for her graduation picnic ($87) by the cost for every attendee ($3).

$87/$3 = 29

Therefore, Rita can have at most 29 attendees if Rita has the above cost parameters.

Hope this helps!
