How I got it:

[tex]\frac{JK}{IJ}[/tex] = cos 76 degrees

[tex]\frac{3.6}{y}[/tex] = 0.2419

x = [tex]\frac{3.6}{0.2419}[/tex]

x = 14.9 ft

this stuff shouldnt be to hard i believe

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:

$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:

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:

[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:

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

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:

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]

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.
