ANSWER

EXPLANATION
The given vectors are:

and

To find the dot product of the two vectors, we multiply the corresponding components and add them.

This implies that,


Therefore the dot product of the two vectors is 51.
I also agree that the answers is the second one have a beautiful day:)
Answer:
37.5 square units
Step-by-step explanation:
A=a+b/2h => 5 + 10 / 2 x 5
Yes, this is a constant function. This means that f(x) = c (c is a constant function) so no matter what the input is for h(x)=6 is, the output will be 6. Therefore this is a straight line with a slope of 0 and thus a linear function.
Answer:
Ans: -21.87 ≅ -22°C
Step-by-step explanation:
T(x)=-22+44e^-0.03x
Initial temperature (x = 0):
T(0) = = -22 + 44e-0.03(0) = -22 + 44(1) = 22°C
After 18 minutes (x = 18):
T(18) = -22 + 44e-0.03(18) = -21.87°C ≅ -22°C
