Answer:
141.12 cm^2
Step-by-step explanation:
The formula for area of a triangle is [tex]h(b1+b2)1/2[/tex]. you have that:
b1, or base 1, = 12.2
b2, or base 2, = 10.2
h, or height, = 12.6
so plug this into the formula:
[tex]12.6(12.2+10.2)1/2\\12.6(22.4)1/2\\12.6*11.2\\141.12[/tex]
Answer:
141.12cm^2
Step-by-step explanation:
First split the trapezoid into two shapes: a rectangle and a triangle.
The area of the rectangle is (10.2cm)(12.6cm) = 128.52cm^2
Finding the area of the triangle is a little trickier. In order to find the base of the triangle, subtract 12.2-10.2=2. The area of a triangle is defined as A=1/2bh, so let's plug in our values:
A = (1/2)(2)(12.6) = 12.6cm^2
Now, add them together.
12.6cm^2 + 128.52cm^2 = 141.12cm^2

Question 3 of 10
The slope of the line below is 4. Which of the following is the point-siope form
of the line?
A. y- 4 = 4(x-3)
B. y+ 4 = 4(x + 3)
C. y+ 4 = 4(x+3)
Dy-4--4(x-3)
Answers
Answer:
The point-slope form of the line is:
[tex]y + 4 = 4(x+3)[/tex]
Hence, option B is correct.
Step-by-step explanation:
We know the point-slope form of the line equation is
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where
m is the slope of the line(x₁, y₁) is the pointGiven
The slope m = 4
From the graph, we can take the point (-3, -4)
So, in our case:
(x₁, y₁) = (-3, -4)
m = 4
now substituting m = 4 and (x₁, y₁) = (-3, -4) in the point-slope form of the line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y - (-4) = 4(x - (-3))[/tex]
[tex]y + 4 = 4(x+3)[/tex]
Therefore, the point-slope form of the line is:
[tex]y + 4 = 4(x+3)[/tex]
Hence, option B is correct.
