Answers

It tells us that angle 3 is a right angle(90 degrees) and it also tells us that angles 1 and 2 are congruent therefore you would take 180-90=90/2=45 so the answer would be 45. Hope this helps:)

Answer:

42°

Emerson struck out 112 times in 350 at bats complete the proportion to represent the percent of strike outs per at bats

Answers

Answer:

Percent of strike outs per-bat = 32%

Step-by-step explanation:

Given:

Number of balls strike out = 112

Total number of ball played = 350

Find:

Percent of strike outs per-bat

Computation:

Percent of strike outs per-bat = [112/350]100

Percent of strike outs per-bat = [0.32]100

Percent of strike outs per-bat = 32%

Write an equation and solve for x.

Answers

Answer:

x = 22

Step-by-step explanation:

All the sides are equal. So, it is and equilateral triangle and so all the angles will be equal.

Each angle of equilateral angle = 180/3 = 60

3x - 6 = 60 {Add 6 to both sides}

3x = 60 +6

3x = 66 {Divide both sides by 3}

x = 66/3

x = 22

Given the coordinate transformation f(x, y) = (- 2x, y) and the domain (0, 5), (8, - 1) and (- 6, 4) what is the range?

Answers

Answer:

{(0, 5), (-16, -1), (12, 4)}

Step-by-step explanation:

Given the coordinate transformation f(x, y) = (- 2x, y) and the domain (0, 5), (8, - 1) and (- 6, 4), to get the range, we will get f(x, y) for all the domain values

For the coordinate (0,5);

f(0, 5) = (-2(0), 5)

f(0, 5) = (0, 5)

For the coordinate (8, -1);

f(8, -1) = (-2(8), -1)

f(8, -1) = (-16, -1)

For the coordinate (-6, 4);

f(-6, 4) = (-2(-6), 4)

f(0, 5) = (12, 4)

Hence the range is {(0, 5), (-16, -1), (12, 4)}

Find g(-4) if g(x) = 8x^2 + 4x

Answers

Answer:

Your answer would be -144

The value of the function g(x) = 8x² + 4x at g(-4) is 112.

What is a function?

A function can be defined as the outputs for a given set of inputs.

The inputs of a function are known as the independent variable and the outputs of a function are known as the dependent variable.

Given, a function g(x) = 8x² + 4x.

Now to obtain the value of g(-4) we'll simply substitute - 4 in place of x.

which is g(-4) = 8(-4)² + 4(-4).

g(-4) = 8×16 - 16.

g(-4) = 128 - 16.

g(-4) = 112.

Answers

180 are empty
............

Answer:

120 seats

Step-by-step explanation:

Total seats in the hall = 300

Percentage of filled seats = 60 %

Number of seats filled = (60 / 100) 300

= 60 * 3

= 180

Therefore, number of empty seats = 300 - 180

The graph of a linear inequality in two variables is the __________ containing all of its solutions.

.line

.half-plane

.parabola

.ellipse

Answers

Answer:

half-plane

Step-by-step explanation:

To draw the line of a linear inequality, we are going to draw a line that divides the coordinate plane into two parts.

Now, while the solution of the inequality lies on a part of the line, the second part of the line does not represent this solution.

Hence, we have a division into two planes. The shaded plane will represent solution to the inequality while the unshaded part will represent the part that is not a solution.

This depends on the sign of the inequality that is present .

The given possible functions are;

1) [tex]y = \sqrt{x - 5} +3[/tex]

The range of values for the above function are;

Domain; x ≥ 5

Range; y ≥ 3

2) [tex]y = \sqrt{x + 5} -3[/tex]
