PLEASE HELP I ONLY HAVE AN HOUR ​

Mathematics
1 answer:
skelet666 [1.2K]3 years ago

Answer:

A. I can't quite see the question, but I'm pretty sure it's A

Step-by-step explanation:

Sin(A) = 1/3

Sin^2(A) + Cos^2(A) = 1

(1/3)^2 + cos^2(A) = 1

1/9 + cos^2(A) = 1

cos^2(A) = 1 - 1/9

cos^2(A) = 8/9

cos(A) = √(8/9)

√8 = √(2 * 2 * 2) = 2√2

√9 = 3

cos(A) = 2√2/3

Write an equation in standard form for a line that passes through (2,2) and (0,-3).
asambeis [7]
So,

The standard form is:
y = mx + b

First, we find "m," the slope.  Subtract the y-coordinates from each other.  Do likewise with the x-coordinates.

2 - -3 = 5
2 - 0 = 2

Slope = 5/2

y= \frac{5}{2} x+b

Now, we can substitute the second solution into this equation for x and y and solve for "b."

-3= \frac{5}{2} *0+b

-3= b

Now we have our complete equation.

y= \frac{5}{2} x-3

Look at the table below. Plot and label points M and N on the coordinate
marta [7]
M = (1,4)
N = (5,2)

For M, you simply move to 1 on the x axis abs for 4 you move on the y axis. Same does for N, for 5 you move on the x axis and for 2 you move on the y axis.

= Floor is 64m.

to find carpet: 8 x 8 x 75%

= 64 x 75%

= 64 x 0.75

= 48

a. The dimensions of the carpet are probably 8 by 8.

b. The area of the floor not covered by carpet is 64, hence 8 x 8.

12.
