Find measure of x! Please help if you know how to do this
Ainat [17]

Answer:

52°

Step-by-step explanation:

(I'm assuming lines JK and HI are parallel)

∠JKA and ∠HIA are corresponding so they are congruent.

Therefore, since ∠JKA is 62, so is ∠HIA. Then knowing the sum of interior angles of a triangle always must be 180, you can just do the math to get 52° as the remaining angle.

66° + 62° + ∠x = 180

∠x = 52°

Which input value produces the same output value for the two functions on the graph? x = −1 x = 0 x = 3 x = 4
grin007 [14]
We know that
The intersection point of both graphs is a common point for both functions, for which for the same input value, both functions will have the same output value.
so
the point of intersection is
for an input value equal to
the output value for both functions is
therefore
the answer is the option
X= 4

The radius of a sphere decreases at a rate of 6 m/sec. find the rate at which the surface area decreases when the radius is 20 m
DanielleElmas [232]

The radius of the sphere decreases at the rate of 6 m/ sec

That is, \frac{dr}{dt}=-6

Surface Area of the sphere of radius r is given by S=4\pi r^2

Differentiating with respect to t,

\frac{dS}{dt}=4\pi (2r)\frac{dr}{dt}=8\pi r\frac{dr}{dt}

\frac{dS}{dt}=8\pi (20)^2(-6)=-960\pi \: m^2/sec
