Answer:

[tex]24.269\ \text{cm}[/tex]

Step-by-step explanation:

[tex]m\angle A=120^{\circ}[/tex]

[tex]b=13\ \text{cm}[/tex]

[tex]c=15\ \text{cm}[/tex]

From the law of cosines we know that

[tex]a^2=b^2+c^2-2bc\cos A\\\Rightarrow a=\sqrt{b^2+c^2-2bc\cos A}\\\Rightarrow a=\sqrt{13^2+15^2-2\times 13\times 15\cos120^{\circ}}\\\Rightarrow a=24.269\ \text{cm}[/tex]

The side [tex]a[/tex] of the triangle is [tex]24.269\ \text{cm}[/tex].

Answer:

Height of light post = 33 feet

Step-by-step explanation:

We will use the trigonometric ratios to find the height of light post

The given scenario forms a right angled triangle with the right angle with the light post.

The distance between light post and the person is the base.

So, base = b = 40 feet

The height of light post will be the perpendicular

So,

Perpendicular = p = x

Angle = 35°

So,

tan (angle) = p/b

tan 35° = p/40

0.7002 =p/40

0.7002*40 = p

p = 28 feet

Since the persons eye level is 5 feet from the ground, 5 feet will be added to perpendicular for actual height of light post.

Height of light post = 28+5 = 33 feet ..

Answer:

Its G

Step-by-step explanation:

they can only work 60 hours so 320 +240 is 560 so it matches the graph

Graph G is the suitable graph to represent the lifeguard's weekly earnings in dollars for working more over 40 hours per week.

A graph can be defined as a pictorial representation or a diagram that represents data or values.

Given that a lifeguard makes $320 per week for 40 hours worked, plus $12 per hour worked after 40 hours. A lifeguard can work no more than 60 hours each week.

For more than 40 hours of labor, the graph on the y-axis will begin at the point (0, 320). Given that the lifeguard is paid $12 per hour, we must choose the graph with the highest slope.

Slope of graph F = (400 - 320)/(10 - 0) = 80/10 = 8

Now, slope of graph G = (500 - 320)/(15 - 0) = 180/15 = 12

Thus, graph G is the correct option.

Answer:

$176

Step-by-step explanation:

Janelle and her best friend Carmen go shopping. the function p(t) = 5x^4 - 3x^3 + 2x^2 + 24 represents how much money each girl spent based on the number of hours they were shopping. If Janelle and Carmen each go shopping for 2 hours how much money did they spend together.

$58

$62

$176

$124

p(t) = 5x^4 - 3x^3 + 2x^2 + 24

Solve when x = 2 hours

p(t) = 5x^4 - 3x^3 + 2x^2 + 24

= 5(2)^4 - 3(2)^3 + 2(2)^2 + 24

= 5(16) - 3(8) + 2(4) + 24

= 80 - 24 + 8 + 24

= $88

how much money did they spent together?

= $88 × 2

= $176

They both spent $176 altogether

Answer:

y=-1/4x-6

Step-by-step explanation:

you fall 1 for every 4, meaning the rise over run is 1/4 and since its falling, it becomes -1/4.

next, b is equal to -6  because that is your y-intercept (where your line meet the y axis).

so, if you put it all together it becomes y= -1/4x-6

Answer:

Slope of required line if both lines are parallel: y=4x-20

Slope of required line if both lines are perpendicular: y=-1/4x+14

Step-by-step explanation:

We need to find equation of line while we are given another line having equation y=4x-6 and passes through point (8,12)

Note: Since it is not given if the required line is parallel or perpendicular to the given line. I will solve for both cases.

If Both lines are parallel the equation of new line will be:

We need to find slope and y-intercept to write equation of new line.

When lines are parallel there slopes are same

So, slope of given line y=4x-6 is 4 (Compare with general equation y=mx+b, m is slope so m=4)

Slope of new line is: m=4

Now finding y-intercept

Using slope m=4 and point (8,12) we can find y-intercept

[tex]y=mx+b\\12=4(8)+b\\12=32+b\\b=12-32\\b=-20[/tex]

y-intercept of new line is: b=-20

Equation of required line having slope m=4 and y-intercept b=-20 is

[tex]y=mx+b\\y=4x-20[/tex]

If Both lines are perpendicular the equation of new line will be:

We need to find slope and y-intercept to write equation of new line.

When lines are perpendicular there slopes are opposite of each other

So, slope of given line y=4x-6 is 4 (Compare with general equation y=mx+b, m is slope so m=4)

Slope of new line is: m=-1/4

Now finding y-intercept

Using slope m=-1/4 and point (8,12) we can find y-intercept

[tex]y=mx+b\\12=-\frac{1}{4} (8)+b\\12=-2+b\\b=12+2\\b=14[/tex]

y-intercept of new line is: b=14

Equation of required line having slope m=-1/4 and y-intercept b=14 is

[tex]y=mx+b\\y=-\frac{1}{4} x+14[/tex]

6 is the answer

Step-by-step explanation:

probably won't help but stay safe :)

Answer:

Part A

This equation is given as

180° = ∠A + ∠B

180° = (2x+5)° + (4x+25)°

Part B

The value of x = 25°

Step-by-step explanation:

We are told in the question that:

Angles A and B are adjacent angles and are supplementary. The measure of ∠A is (2x+5)∘ and the measure of ∠B is (4x+25)∘.

Question 1 Part A Write an equation that can be used to determine the value of x.

Two angles are called supplementary when their measures add up to 180 degrees.

This equation is given as

180° = ∠A + ∠B

180° = (2x+5)° + (4x+25)°

Part B

Solving the equation

180° = (2x+5)° + (4x+25)°

180° = 2x + 5 + 4x + 25

180° = 6x + 30

Collect like terms

180° - 30° = 6x

150° = 6x

x = 150/6

x = 25°

Enter the correct answer in the box.

Step-by-step explanation:

31, (25/2) (or 12.5)

Given :

The total cost can be represented by the equation 2c + (c+5) = 43.97, where c is the cost of one lower-priced cd.

To Find :

The cost of the higher priced cd.

Solution :

Solving given equation :

2c + c + 5 = 43.97

3c + 5 = 43.97

3c = 43.97 - 5

3c = 38.97

c = $12.99

Therefore, cost of higher priced cd is $( 12.99 + 5 ) = $17.99 .

Hence, this is the required solution.

Answer:

y = 2x

Step-by-step explanation:

By inspection, we can see the line crossing through the points: (0,0) , (1,2)

[Use the slope formula to find m]

m = (Y2 - Y1) / (X2 - X1)

m = (2 - 0) / (1 - 0)

m = 2/1 = 2

[Use the point slope formula to find equation]

(y-y0) = m(x-x0)

y - 0 = 2(x - 0)

y = 2x
