Answer:
0
Step-by-step explanation:
The value of x that will result for the rational expression to be undefined will be the values that will give 0 value for the denominator.
A. 7
<span>2(7)^2 -32 = 66
</span>
<span>B. 4
</span>2(4)^2 -32 = 0 <span>-------> undefined</span>
C. 2
2(2)^2 -32 = -24
<span>D. -2
</span>2(-2)^2 -32 = -24
<span>E. -4
</span>2(-4)^2 -32 = 0 -------> undefined
F. -7
2(-7)^2 -32 = 66
Answer:
E. x² + 11x - 42 = 0
Step-by-step explanation:
let the square sides be x
A = bh = (x + 3 + 3)(x + 2 + 3) = 72
(x + 6)(x + 5) = 72
x² + 11x + 30 = 72
x² + 11x - 42 = 0
Answer:
Vz = arccos(0.1673413807) = 80.37º
Step-by-step explanation:
The inverse function of the cosine is the arc cosine.
That means, that if we have that cos a = 1, a is the angle which has cosine equals 1, so a = arccos(1) = 0º.
In this problem, we have that:
cos(Vz) = 0.1673413807
Vz = arccos(0.1673413807) = 80.37º
Step-by-step explanation:
At d, f'(x) is increasing (concave up), but it is not positive. The tangent line at that point has a negative slope.
