Answer: Vector travelling 4 units to the left and 1 unit up, facing northwest.

Step-by-step explanation:

The original shape is ABC, while the translated shape is A'B'C'.

The translation is 4 units to the left and 1 unit up.

The correct vector will display as a vector travelling 4 units across and 1 unit down, facing northwest.

The first attached image travels 4 units across and 1 unit down, and faces the correct direction (northwest).

The second attached image travels 4 units across and 1 unit down, but it faces the wrong direction (southeast).

The third image travels 1 unit across and 2 units down. This is incorrect.

The fourth image travels 1 unit across and 2 units down. This is incorrect.

The correct answer is the first attached image (linked in comments)

What is the volume of the right prism?

Serggg [28]

We know that:
$V = l \times w \times h$

Substituting known values, we have:
$V= 4ft \times 4ft \times 15ft$
$V= 240ft^{3}$

Which equation represents a line that is perpendicular to line PQ?

valentinak56 [21]

Answer:

B. y=1/3x+4

Step-by-step explanation:

Hi there!

We are given the line PQ and we want to find the line that is perpendicular to it

Perpendicular lines have slopes that are negative and reciprocal. When they are multiplied together, the result is -1

So first, let's find the slope of the line PQ

The point P is given as (-8, 7) and the point Q is given as (-4, -5)

The formula for the slope calculated from two points is $\frac{y_2-y_1}{x_2-x_1}$ where ( $x_{1}$ $y_1$ ) and ( $x_2$ , $y_2$ ) are points

We have the needed information for the slope, but let's label the values of the points to avoid any confusion

x1=-8

y1=7

x2=-4

y2=-5

Now substitute into the formula (m is the slope, and remember: the formula contains SUBTRACTION):

m= $\frac{(-5-7)}{(-4--8)}$

simplify

m= $\frac{-5-7}{-4+8}$

add

m=-12/4

divide

m=-3

So the slope of the line PQ is -3

As said above, perpendicular lines have slopes that have a product of -1

So to find the slope of the line perpendicular to PQ, use this formula:

-3m=-1

divide both sides by -3

m=1/3

The only line that has a slope of 1/3 is B (y=1/3x+4), so B is the answer.

Hope this helps!

find the area of each sector. Use the 3.14 as the value of pi. Round your answer to the nearest tenth. Part 4

Yuri [45]

Answer:

1) 378.1 in²

2) 8.4 m²

Step-by-step explanation:

Area of sector= $\frac{θ°}{360°} \times \pi {r}^{2}$

1) Area of sector

$= \frac{150°}{360°} \times 3.14 \times {17}^{2} \\ = 378.1 \: in^{2} \\ (nearest \: tenth)$

2) Area of sector

$\frac{60°}{360°} \times 3.14 \times {4}^{2} \\ = 8.4 \: m^{2} \\ (nearest \: tenth)$
