thought: (0,-4), slope=1

Answers

Answer:

D choice.

Step-by-step explanation:

Pass through (0,-4) means that the graph intercepts y-axis at (0,-4)

[tex]y = mx + b[/tex]

Therefore, our b is -4

[tex]y = mx - 4[/tex]

Slope = 1 means that the value of m is 1. Substitute m = 1.

[tex]y = x - 4[/tex]

Therefore, the answer is D choice.

Marcus throws a football straight up into the air. After it reaches its maximum height of 20 feet, it descends back to ground. What is the independent and dependent?

Answers

Answer:

Independent = Force used to throw foot ball (Marcus)

Dependent = Maximum Height

Step-by-step explanation:

The independent variable is h and the dependent variable is u.

What is kinematics?

The study of motion without considering the mass and the cause of the motion.

We know that the equation of motion is given as,

v² - u² = -2gh

Where v is the final velocity, u is the initial velocity, g is the acceleration due to gravity (9.81), and h is the height of the ball.

We know that the final velocity will be zero at the highest point. Then the equation will be given as,

0² - u² = -2 × 9.81 × h

u² = 19.62h

u = √(19.62h)

Then the independent variable is h and the dependent variable is u.

(Choice A)
A
Multiply/divide both sides by the same non-zero constant

(Choice B)
B
Multiply/divide both sides by the same variable expression

(Choice C)
C
Add/subtract the same quantity to/from both sides

(Choice D)
D
Add/subtract a quantity to/from only one side

2) Based on the previous answer, are the equations equivalent?

In other words, do they have the same solution?

Choose 1 answer:

(Choice A)
A
Yes

(Choice B)
B
No

Answers

Answer:

1. C   Add/subtract the same quantity to/from both sides

2. A  Yes

Step-by-step explanation:

Start with Equation A.

3x - 1 = 7

Add 1 to both sides.

3x = 8

First question:

How can we get Equation B from Equation A?

Answer:

C   Add/subtract the same quantity to/from both sides

Second question:

Based on the previous answer, are the equations equivalent?

Since by doing a valid step (adding 1 to both sides) Equation A became Equation B, the two equations are equivalent.

At a high school championship game 1200 tickets were sold. Student tickets cost $1.50 each and adult tickets cost $5.00 each. The total revenue collected for the game was $3200. How many of each ticket were sold for the game?

Answers

Answer:

Students= 800

Adults= 400

Step-by-step explanation:

Given data

number of tickets= 1200

let students be x

and adults be y

x+y= 1200--------------------1

'

The total revenue collected for the game was $3200

so

1.5x+5y=3200-------------2

Solve 1 and 2 for x and y

x= 1200-y

put this is 2

1.5( 1200-y)+5y=3200-------------2

1800-1.5y+5y= 3200

3.5y= 3200-1800

3.5y=1400

Divide both sides by 3.5

y= 1400/3.5

y=400

Put y= 400 in 1

x+400= 1200

x= 1200-400

x=800

Catarina and Tom want to buy a rug for a room that is 8 by 12. They want to leave an even strip of flooring uncovered around the edges of the room. How wide a stip willhave if they buy a rug with an area of 32 square feet

Answers

Answer:

The strip would be 2 ft wide

Step-by-step explanation:

Let the strip be x ft long

since it is on either sides, it will take a space each of 2x

So the dimensions of the rug will be;

(8-2x) and (12-2x)

The product of these will give the area of the rug

We have this as;

(8-2x)(12-2x) = 32

96-16x-24x + 4x^2 = 32

4x^2-40x + 96-32 = 0

4x^2 -40x + 64 = 0

x^2 - 10x + 16 = 0

x^2 - 8x - 2x + 16 = 0

x(x-8) -2(x-8) = 0

(x-2)(x-8) = 0

x = 2 or 8

The value 8 will not be possible as it will need to negative dimensions

So the possible dimensions will be;

(8-2(2)) and 12-2(2)

= 8-4 and 12-4

= 4 ft by 8 ft

There are 7 days in a week

Each day except for Wednesday is 10 hours, and on Wednesday it is 11...

Monday = 10

Tuesday = 10

Wednesday = 11

Thursday = 10

Friday = 10

Saturday = 10

Sunday = 10

If you add them all up you get 71 hours. And songs....

Monday = 3

The probability of a tropical storm becomes a hurricane is 0.53. If the weather service predicts 6 more tropical storms, what is the probability that exactly 5 of them become hurricanes?

Answers

Answer:

0.1179

Step-by-step explanation:

Given that :

p = 0.53

n = 6 ; x = 5

P(x = 5)

According to the binomial probability formula :

P(x = r) = nCr * p^r * (1 - p)^(n - r)

P(x = 5) = 6C5 * 0.53^5 * (1 - 0.53)^(6 - 5)

P(x = 5) = 6C5 * 0.53^5 * 0.47^1

P(x = 5) = 6 * 0.53^5 * 0.47^1

P(x = 5) = 0.117931129026

= 0.1179

How many square meters are enclosed in the track? Use 3 for π.

Enclosed in the track is __ square meters

Answers

Answer:

Area = 3,656.6 m²

Step-by-step explanation:

Area enclosed by the track is composed of two semicircles and a rectangle.

Area = area of two semicircles + area of rectangle

= 2(½*πr²) + L*W

Where,

radius of semicircle (r) = ½of 40 m = 20 m

Length of rectangle (L) = 60 m

Width of rectangle (W) = 40 m

Plug in the values

Area = 2(½*π*20²) + 60*40

Area = 400π + 2,400

Area = 3,656.6 m² (aooroximated to nearest tenth)
