Answer:

b. 3631.68 m²

Step-by-step explanation:

The surface area of a sphere can be found using the formula ...

A = πd² . . . . where d is the diameter

For a diameter of 34 m, the area is ...

A = π(34 m)² = 1156π m² ≈ 3631.68 m²

if its diameter is 34, then its radius is half that or 17.

$\textit{surface area of a sphere}\\\\ SA=4\pi r^2 ~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ r=17 \end{cases}\implies \begin{array}{llll} SA=4\pi (17)^2\implies SA=1156\pi \\\\\\ SA\approx 3631.68~m^2 \end{array}$

Svet_ta [14]

the answer is C. x ≥ 8.00 and x < 9.50
proof
x ≥ 8.00 is equivalent to 8.00 ≤ x, and we have also x < 9.50
so x ≥ 8.00 and x < 9.50 or 8.00 ≤ x < 9.50

Answer:

$y=-4x+2$

Step-by-step explanation:

First we find the slope of the line AB passing through the point (2,0)
line AB is perpendicular to the line $y=\frac{1}{4}x-3$ , this equation is slope intercept for, which is $y=mx+b$ so our m or slope is $\frac{1}{4}$
Since the slope of line AB is perpendicular to $m=\frac{1}{4}$ then we use the equation $slope of line1\times slopeofline2=-1$ , so what do we multiply $\frac{1}{4}$ by to get -1? -4 right, so that's the slope of line AB with the point (2,0)
Now line CD is parallel to line AB, that means it has the same slope as AB, so slope of CD is -4
So we make the equation $y-y_1=m(x-x_1)$ so m= -4 and our point is (-1,6)
$y-(6)=-4(x-(-1)\\y-6=-4x-4\\y=-4x-4+6\\y=-4x+2$ thats the equation of line side CD
