PLS ANSWER !!!! what is the formula when finding the slope given in two ordered pairs

1 answer:

5 0

Answer: Since you already know that the ordered pair is in the format of (x, y), then you can label one of the ordered pairs as 1 and kind of distribute it to get 1(x, y) = (x-sub1, y-sub1). Then just use the slope formula (y2-y1)/(x2-x1).

Find the surface area of the figure

belka [17]

Answer:

122.30 cm²

Step-by-step explanation:

The figure is a triangular prism.

Formula for calculating surface area of a triangular prism = bh + L(S1 + S2 + S3)

Where,

b = 11 cm

h = 4.3 cm

S1 = 8 cm

S2 = 6 cm

S3 = 11 cm

L = 3 cm

Surface area = 11*4.3 + 3(8 + 6 + 11)

= 47.3 + 3(25)

= 122.3 cm²

HELP WITH THIS QUESTION PLEASE!

Answer:

23.7°

9.1~ft

Step-by-step explanation:

Formula for the area of a sector of central angle n (in degrees) and radius r:

$A = \dfrac{n}{360^\circ}\pi r^2$

We have:

A = 100 ft^2

r = 22 ft

We need to find:

$100 = \dfrac{n}{360^\circ}\pi (22^2)$

$n = 23.7^\circ$

The central angle measures 23.7°.

Formula for the length of an arcs of a circle with central angle n (in degrees) and radius r:

$s = \dfrac{n}{360^\circ}2 \pi r$

We have:

n = 23.7°

r = 22 ft

We need to find:

$s = \dfrac{74.4}{360}2 \pi (22 ft)$

$s = 9.1~ft$

On a number line, A is at -2 and B is at 4.

OleMash [197]

It would be at 2. Here is why: -2 and 4 are 6 places away from each other. Now divide that by 3 (for the thirds). so each third is 2. Now thirds 2will be four, so add that to -2 and you get 2.
