this is kinda easy and im gonna assume that the 4 is a exponent cuz f(2)=2(3)^4 then f=81

Which graph represents a function with direct variation?

kirill [66]

Answer:

The graph that represent direct variation in the attached figure

Step-by-step explanation:

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $y/x=k$ or $y=kx$

In a proportional relationship the constant of proportionality k is equal to the slope m of the line <em>and the line passes through the origin </em>

The radius of a right circular cone is increasing at a rate of 4 inches per second and its height is decreasing at a rate of 5 i

solmaris [256]

Answer:

$V' = 900\pi$ $in^{3} /sec$

Step-by-step explanation:

V = $\frac{1}{3} \pi r^{2}h$

$V' = \frac{2\pi rh *r'}{3} + \frac{\pi r^{2} *h'}{3}$ (using differentiation product rule)

plug known values in for r, h, r', and h'

$V' = \frac{2\pi (10)(40)(4)}{3} + \frac{\pi (10^{2} )(-5)}{3}$

$V' = \frac{3200\pi }{3} - \frac{500\pi }{3} \\V' = \frac{2700\pi }{3} \\$

$V' = 900\pi$ $in^{3} /sec$

Triangles ABC and DEF are similar. Find the missing angles.

Ratling [72]

Angle A and D are similar
Angle B and E are similar
Angle C and F are similar

So this means they have congruent angles, meaning whichever angles are similar the angles will also be similar.

So since angle A is 62 degrees, angle D is 62 degrees too.

Since angle E is 80 degrees, angle B has to be 80 degrees as well.

All triangles add up to 180 degrees, so to find the angle measure of angle C and F, do:

180-(62+80)
180-142
= 38 degrees

So angles C and F are 38 degrees

Conclusion:
angles A and D: 62 degrees
angles B and E: 80 degrees
angles C and F: 38 degrees
