Answer:
f(7) = 158
Step-by-step explanation:
To evaluate f(7) substitute t = 7 into f(t)
f(7) = 3(7)² + 11 = (3 × 49) + 11 = 147 + 11 = 158
Answer:
I think is C.............
m^2 + 16m +64 = (m+8)^2
Factor using the perfect square rule.
Answer:
310 837 500 m³
Step-by-step explanation:
The l<em>inear dilation factor</em> (LDF) is 15.
The equation for the <em>volume dilation facto</em>r (VDF) is
VDF = LDF³
VDF = 15³ = 3375
V' = VDF × V
V' = 3375 × 92 100 = 310 837 500 m³
The volume of the dilated pyramid is 310 837 500 m³.
First you'll need to get the same denominator. So instead of 3/5 and 3/8 you'll have 24/40 and 15/40. Now that we've changed the value of the denominator, the 40/40 will now represents the 1 hour that Jenny has before bedtime. So you add 24/40 and 15/40 and get 39/40. 39/40 stands for the time that Jenny has already spent brushing her teeth and texting her friend all together. Since the 1 hour is 40/40 subtract 39/40 from it to get 1/40. 1/40 is equal to the rest of the time Jenny spends reading or 1.5 minutes.
