Answer:

D. y = -0.32x² -1.26x +15.81

Step-by-step explanation:

This is one of those multiple-choice questions where you only need a vague idea of what the answer is supposed to look like.

In this case the answer must be a quadratic equation with a negative leading coefficient. (The parabola opens downward.)

The only answer choice that is a 2nd degree polynomial with a negative leading coefficient is choice D.

A: linear equation

B: exponential equation

C: quadratic that opens upward (positive leading coefficient)

D: quadratic that opens downward -- the answer you're looking for

Answer:

$T' = (-7,10)$

Step-by-step explanation:

Given

$T = (10,7)$

$r = 270^o$ counterclockwise

Required

Graph of T'

The rule to this is:

$(x,y) \to (-y,x)$

So, we have:

$T(10,7) \to T' (-7,10)$

Hence:

$T' = (-7,10)$

Salsk061 [2.6K]

Answer: $1.50(\pi x^2-2\sqrt{2}x^2)$

Step-by-step explanation:

Here the function that shows the total area of mulch,

$m(x)=\pi x^2-2\sqrt{2}x^2$

Also, the function that shows the total cost mulch that requires,

$g(m) = 1.50 m$

By putting the value of m,

We get,

$\implies g(m) = 1.50( \pi x^2-2\sqrt{2}x^2 )$

Where x is the radius of the circle.

Thus, First option is correct.
