Answer 1

Answer:

Perimeter=25 units

Area= 43 units^2

Step-by-step explanation:

one side = 5 units so perimeter is 5x5=25

split into 5 equal triangles

base =5, height =3.44, formula for area=(base)(height)(0.5)

area of each triangle =(5)(3.44)(0.5)=8.6

entire area=5(8.6)=43

how do you solve this problem step by step
y=x+3
y=x-1

Answers

Step-by-step explanation:

since they have the Same slop (1) and different y-intercepts then they're parallel and there isn't a solution for this.

set them like an equation: x+3=x-1
then cancel the equal terms on both sides of the equation which would end you up with: 3= -1, after that your answer would be no solution since there’s no terms in order to get you an answer.

Answer:

∠ BAC ≈ 67.4°

Step-by-step explanation:

Using the sine ratio in the right triangle.

sinA = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{BC}{AB}[/tex] = [tex]\frac{12}{13}[/tex] , then

∠ A = [tex]sin^{-1}[/tex] ([tex]\frac{12}{13}[/tex] ) ≈ 67.4° ( to 1 dec. place )

Find the product of (x + 5)^2

Answers

Answer:

x^2 + 10x + 25.

Step-by-step explanation:

When you have questions like these, where there is an (x + something)^2,

you just need to put it into this form:

x^2 + ____x + ____.

For the first blank, add 5 + 5 in this case.

For the second blank, multiply 5 * 5.

5 + 5 = 10.

5 * 5 = 25.

So the final answer is:

x^2 + 10x + 25.

Find the equation of the line

Answers

Given:

The graph of a line.

To find:

The equation of the line.

Solution:

From the given graph it is clear that the line passes through the points (0,-2) and (4,1). So, the equation of the line is

[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

[tex]y-(-2)=\dfrac{1-(-2)}{4-0}(x-0)[/tex]

[tex]y+2=\dfrac{1+2}{4}(x)[/tex]

Subtracting 2 from both sides, we get

[tex]y=\dfrac{3}{4}x-2[/tex]

Therefore, the equation of given line is [tex]y=\dfrac{3}{4}x-2[/tex].

Answer:

7 - 3 = 4

1 - (-12) = 13

9 + 11 = 20

7 - (-4) = 28

6 × (-3) = -18

(-8) × 9 = -72

5 + (-8) = -40

(-13) -2 = -26

(-13) + (-5) = 65

(-15) × -1 = 16

(-11) -12 = 132

(-9) × 3 = -27

14 + 8 = 22

60 ÷ (-4) = -15

(-4) + (-14) = -18

20 ÷ 5 = 4

(-12) + 8 = -96

6 + 11 = 17

(-14) × 7 = -98

(-12) - 15 = 180

12 × 13 = 156

Find the area of a circle with a diameter of 2 feet use 3.14 use pi Also please say all the. steps if you can

Answers

Given:

Diameter of a circle = 2 feet

To find:

The area of a circle.

Solution:

We know that, area of a circle is

[tex]A=\pi r^2[/tex]

Where, r is the radius of the circle.

Diameter of a circle = 2 feet

So, radius of the circle = [tex]\dfrac{2}{2}=1[/tex] feet

Putting r=1 and [tex]\pi=3.14[/tex] in the above formula, we get

[tex]A=(3.14)(1)^2[/tex]

[tex]A=(3.14)(1)[/tex]

[tex]A=3.14[/tex]

Therefore, the area of the circle is 3.14 sq. feet.
