Answer:
B. 3.34s
Step-by-step explanation:
Find t when the object hit the ground, h(t)=0.
h(t)=-16t²+178
0=-16t²+178
16t²=178
t²=11.125
t=√11.125=3.33541601603s

Answer:
(x + 1)(5x - 3)
Step-by-step explanation:
Given
5x² + 2x - 3
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term, that is
product = 5 × - 3 = - 15 and sum = + 2
The factors are + 5 and - 3
Use these factors to split the x- term
5x² + 5x - 3x - 3 ( factor the first/second and third/fourth terms )
= 5x(x + 1) - 3(x + 1) ← factor out (x + 1) from each term
= (x + 1)(5x - 3) ← in factored form
Answer:
30 milkshakes and 40 root beer floats
Step-by-step explanation:
Set up a system of equation (r is root beer and m is milkshake)
2.75r+6m=290
m+10=r
Substitute
2.75(m+10)+6m=290
2.75m+27.5+6m=290
8.75m=262.5
m=30
Now plug in 30 and solve for r
30+10=40
