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

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:

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:  B

Step-by-step explanation:

Answer:104

Step-by-step explanation:

So you would take 260 miles and divide by 4 hours to get 65 mph. And since the rate slows by 20%, you would subtract 13 from 65 giving you 52. So the new speed of the tornado is 52 mph. And take that and multiply it by 2 hours to get 104 miles.

Answer:

Step-by-step explanation:

The set up will give a right angled triangle;

altitude (opposite side ) = 1700m

angle of depression = 25degrees

Required

distance from the plane to the rock (adjacent side)

Using the SOH, CAH, TOA identity;

According to TOA

tan 25 = opposite/adjacent

tan25 = 1700/adj

adj = 1700/tan 25

adj = 1700/0.4663

adj = 3,645.72m

Hence the distance from the plane to the rock to 1 dp is 3,645.7m

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.

Answer:

Step-by-step explanation:

Lines m and l are the parallel lines and a line 'n' is a transverse intersecting these lines.

m∠2 = 50°

m∠1 + m∠2 = 180° [Linear pair of angles]

m∠1 = 180° - 50°

m∠1 = 130°

m∠3 = m∠1 = 130° [Vertically opposite angles]

m∠3 + m∠5 = 180° [Consecutive interior angles]

m∠5 = 180° - m∠3

        = 180° - 130°

        = 50°

m∠6 + m∠5 = 180° [Linear pair of angles]

m∠6 = 180° - 50° = 130°

From the given diagram

angle 1= 130 degrees

Angle 3 = 130 degree

Angle 5= 50 degree

Angle 6= 130 degree

Given :

the two parallel lines are cut by a transversal

Angle 1  and angle 2  are linear pair of angles

Sum of angle 1  and angle 2 is 180

[tex]<1+<2=180\\<1+50=180\\<1=180-50\\<1= 130[/tex]

Angle 1  and angle 3 are vertical opposite angles

They are equal

[tex]<1=<3\\130=<3\\<3= 130[/tex]

When two parallel lines are cut by transversal , corresponding angles are equal

<5= <2

<5=50

Alternate exterior angles are congruent

<6=<1

<6=130

angle 1= 130 degrees

Angle 3 = 130 degree

Angle 5= 50 degree

Angle 6= 130 degree

Answer:12/18 = 6/9 = 2/3

Step-by-step explanation:

Answer:

The equation of the line will be:

[tex]y=\frac{5}{3}x-1[/tex]

Step-by-step explanation:

Given the points

Finding the slope between (3, 4) and (12, 9)

[tex]\left(x_1,\:y_1\right)=\left(3,\:4\right),\:\left(x_2,\:y_2\right)=\left(12,\:19\right)[/tex]

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\frac{19-4}{12-3}[/tex]

[tex]m=\frac{5}{3}[/tex]

The equation of the line can be obtained using the point-slope form of the equation of the line

[tex]y-y_1=m\left(x-x_1\right)[/tex]

substituting the values m = 5/9 and the point (3, 4)

[tex]y-4=\frac{5}{3}\left(x-3\right)[/tex]

[tex]y-4+4=\frac{5}{3}\left(x-3\right)+4[/tex]

[tex]y=\frac{5}{3}x-1[/tex]

Therefore, the equation of the line will be:

[tex]y=\frac{5}{3}x-1[/tex]
