The answer is definitely B
Answer:
x = -6,6
Step-by-step explanation:
h(x)=−5x^2 +180
Assuming you want to find the zero's
0 =−5x 2 +180
Subtract 180 from each side
0-180=−5x^2 +180-180
-180 = -5x^2
Divide each side by -5
-180/-5 = -5x^2/-5
36 = x^2
Take the square root of each side
±sqrt(36) = sqrt(x^2)
±6 = x
x = -6,6
To find how long Lori has run do 1/10 x 26.2
1/10 x 131/5
= (1x131) / (10x5)
= 131/50 or 2 and 31/50 miles long
V = (4/3)π*r^3
.. = (4/3)*3.14*(5.3 ft)^3
.. = 623.3 ft^3
