D
7•4 =28, -5•0 =0... 28+0=28
Answer:
60 degree
Step-by-step explanation:
E,A,D is a straight line .
Straight line=180 degree
100+20=120 -180=60
therefore X=60
-3x^2-6x+2x-4
=-3x (x-2)+2 (x-2)
=(-3x+2)(x-2)
-3x+2=0
X=2/3
X-2=0
X=2
Hope it helps! !!!!
The answer to this question is y' = 10x^2 + 6. You have to use the power rule to bring the exponent down as a coefficient and then reduce the exponent by 1. Do it for all the terms using the sum rule for derivatives (derivative of a sum of the sum of its derivatives).
Answer:
k = 9.6
Step-by-step explanation:
When dealing with inverse variation, the two variables vary in opposite directions. This means that as the first variable increases, second variable decreases and as the first variable reduces,the second variable increases.
Y varies inversely with x.
So as y increases, x reduces and as y reduces, x increases.
We would proceed by introducing a constant of variation, k
y = k/x
From the information given,
The constant of variation = k
The value if x = 6.4
The value of y = 1.5
To find the value of k
y = k/x
k = yx = 1.5 × 6.4
k = 9.6
