please help me, i have no clue what to do all it says is find the slopeof the line that passes through the given two points using ratio method.
Answers
Answer:
Δy = 9
Δx = -6
Slope = -3/2
Step-by-step explanation:
The slope formula is the change in y (Δy) over change in x (Δx).
Δy = [tex]y_2-y_1[/tex]
Δx = [tex]x_2-x_1[/tex]
We are given the points of (5,-3) and (-1,6).
[tex]m=\frac{6-(-3)}{-1-5}=\frac{9}{-6}=\boxed{-\frac{3}{2}}[/tex]
The slope is -3/2.

Answer:
Area of the sector = [tex]\frac{\pi }{8}[/tex] cm²
Step-by-step explanation:
Measure of the given arc = 45°
Central angle formed by the arc = 45°
Formula to be used,
Area of the sector bounded by the arc = [tex]\frac{\text{Central angle}}{360}\times \pi r^{2}[/tex]
Here, r = radius of the circle
Area of the sector = [tex]\frac{45}{360}(\pi)(1)^2[/tex]

640 units squared
Step-by-step explanation:
The shape below is a trapezoid.
The formula for the area of a trapezoid is average of the bases times the height.
The bases are the parallel lines that make up 2 of the sides of the trapezoid.
The height is the line dotted line that creates right angles and is the distance between the two bases.
The bases are 24 and 40.
To find the average, we add them together and divide by 2
(24+40)/2=64/2=32
Now, we multiply 32 by the height, which is given as the length of 20.
32*20=640
the area of the trapezoid is 640 units squared

What is the range of the function y = 3x + 2 when the domain is {-3, 0, 2}?
Answers
Answer:
{-7, 2, 8}
Step-by-step explanation:
We see that the domain is limited to three x-values: -3, 0 and 2. To find the range (which is the set of all y-values) we just need to plug-in these x-values and find the corresponding y-values.
So our equation is:
y = 3x + 2
Then we substitute for the x-values:
y = 3(-3) + 2
y = -9 + 2
y = -7
y = 3(0) + 2
y = 0 + 2
y = 2
y = 3(2) + 2
y = 6 + 2
y = 8
So our range would be {-7, 2, 8}.
