Answer:

It's diameter would be 12

Step-by-step explanation:

To find the radius of the circle, you have to find the distance between two points, the difference between (-5,-2) and (-5,-8) is 6. Since diameter is twice the radius, the diameter would 12.

The graph of f ′ (x), the derivative of f of x, is continuous for all x and consists of five line segments as shown below. Given

Rom4ik [11]

$f'(x)\ge0$ for all $x$ in [-3, 0], so $f(x)$ is non-decreasing over this interval, and in particular we know right away that its minimum value must occur at $x=-3$ .

From the plot, it's clear that on [-3, 0] we have $f'(x)=-x$ . So

$f(x)=\displaystyle\int(-x)\,\mathrm dx=-\dfrac{x^2}2+C$

for some constant $C$ . Given that $f(0)=7$ , we find that

$7=-\dfrac{0^2}2+C\implies C=7$

so that on [-3, 0] we have

$f(x)=-\dfrac{x^2}2+7$

and

$f(-3)=\dfrac52=2.5$

What is 2 3rds of 18

Anna35 [415]

You first multiply across $\frac{2}{3}$ and $\frac{18}{1}$ = $\frac{36}{3}$ . Then you divide the numerator(the top) by the denominator(the bottom) which is $\frac{36}{3}$ = $\frac{12}{1} or$ just 12

The total area of a checkerboard is 256 square inches.

Gala2k [10]

Answer:

The side length of the small squares in inches is 2 inches

Step-by-step explanation:

Given

Area of checker board = 256 square inches

A regular checker board has 64 small squares in total that means that 256 is the area of all 64 squares. To find the area of one small square, the total area will be divided by 64

So,

$Area\ of\ one\ small\ square = A = \frac{256}{64}\\= 4\ in^2$
