Answer:

(4x × 5)² or (4x × 5) (4x × 5)

Step-by-step explanation:

FOIL- first outer inner last

4x times 4x = 16x²

4x times 5 equals 20x, 4x times 5 again is 20x

combine the two terms and get 40x

5 times 5 is 25

so 16x²+40x+25

The piecewise function all the way to the left (x + 3) should have an ending point shaded in. [At x = -2] The next function ((x^2) -1) should have both ending points left unshaded. Finally, the logarithm function should have a shaded in starting point [At x = 1] and should have an unshaded ending point at x = 3.

A right cylinder has a radius of 3 and a height of 12. What is its surface area?

shepuryov [24]

Answer:

Surface Area = 283

Step-by-step explanation:

Radius = 3

Height = 12

Formula for suface area is SA= 2πrh+2πr^2

let "r" be for radius

let "h" be for height

SA=2*π*3*12+2*π*3^2

SA=282.74

round to the nearest ones spot and that will make the surface area = 283

Which triangle would be most helpful in finding the distance between the points (-4, 3) and (1,-2) on the coordinate

earnstyle [38]

Answer:

On a coordinate plane, a triangle has points (negative 4, 3), (negative 4, negative 2), (1, negative 2).

Step-by-step explanation:

The points (-4,3), (1,2) and (-4, -2) would form a right triangle when graphed and connected by lines.

(-4,3), (1,2) and (1,3) would also work as well

Question 5(Multiple Choice Worth 1 points)

Snezhnost [94]

Given:

The graph passes through the points (0,-20) and (4,10).

To find:

The equation of line that most closely represents the line depicted in the graph.

Solution:

If a line passing through two points, then the equation of line is

$y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)$

The given line passes through the points (0,-20) and (4,10). So, the equation of line is

$y-(-20)=\dfrac{10-(-20)}{4-0}(x-0)$

$y+20=\dfrac{10+20}{4}(x)$

$y+20=\dfrac{30}{4}x$

$y+20=\dfrac{15}{2}x$

Subtracting 20 from both sides, we get

$y=\dfrac{15}{2}x-20$

The function form is

$f(x)=\dfrac{15}{2}x-20$

f of x equals fifteen halves times x minus 20.

Therefore, the correct option is B.
