Answer:
(b)
Step-by-step explanation:
A suitable calculator or spreadsheet can find the matrix product for you. Here, the answer choices differ in their upper left term, so we can determine the correct choice by finding the value of that term. It is the dot product of the first row of B and the first column of A.
(5)(3) +(7)(3) +(3)(2) = 15 +21 +6 = 42
This matches choice B.
Answer:
volume = 13500
Step-by-step explanation:
For a given pyramid, its volume can be determined by:
volume of pyramid =
Where: l is the base length, w is the base width and h id the height of the pyramid.
For the given question, l 30 cm, w = 30 cm and h = 45 cm.
So that,
volume =
=
= 13500
volume = 13500
The volume of the pyramid is 13500 .
Answer:
(C)y=0
Step-by-step explanation:
An exponential function of the form always has a horizontal asymptote at y = c.
Given our function
Comparing with the form, , we observe that c=0.
Therefore, the exponential function has an <u>asymptote at y=0.</u>
The correct option is C.
