Answer: -14.8
Procedure:
Get the angles measures
Cross multiply
Plog in the calculator 20cos(138)x
And you get -14.8628....
Round your answer -14.8
P = l + w + l + w or 2l + 2w
answer is A. first one.
Answer:
D
Step-by-step explanation:
Two matrices are equal when they
- have the same sizes (so options A and B are false)
- have equal corresponding elements (so option C is false, because -6≠6, -6.5≠6.5, 1.7≠-1.7 and so on)
If in option D the second row is 2 -8.5 19.3 , then these matrix is equal to the given.
Answer:
y = -1/6x + 2
Step-by-step explanation:
Slope: (-6,3) and (6,1) = (1-3) / (6 - - 6)
= - 2/12 = -1/6
b = 3 - (-1/6)(-6)
b = 3 - 1
b = 2
