Find the slope and y-intercept of the graph of the linear equation.
12. y= 4x

Answers

Answer 1

Answer:

Slope = 4, y-intercept = (0,0)

Step-by-step explanation:

This problem is written in slope-intercept form. Meaning it is in the form y=mx+b. "M" is the slope, and "B" is the y-intercept. With that information, we easily see that 4 is the slope of the graph (it will go up 4 points for everyone one point it goes right). It seems that there is no y-intercept though, that is because we are expected to know that y=4x is the same as y=4x+0. Meaning, the problem can also be written this way and the y-intercept must be 0.

The surface area of a sphere is 200.96 square centimeters. What is the approximate volume of the sphere? Use 3.14 for π. Round your answer to the nearest hundredth.

Answers

Answer:

[tex]267.95 cm^3[/tex]

Step-by-step explanation:

We need to first find the radius of the sphere.

The surface area of a sphere is given as:

[tex]A = 4\pi r^2[/tex]

where r is the radius

Therefore:

[tex]200.96 = 4 * 3.14 * r^2\\\\=> r^2 = 200.96 / 12.56\\\\r^2 = 16\\\\r = \sqrt{16} \\\\r = 4cm[/tex]

The radius of the sphere is 4 cm.

The volume of a sphere is given as:

[tex]V = \frac{4}{3} \pi r^3[/tex]

Therefore, the volume of the sphere of radius 4 cm is;

[tex]V = \frac{4}{3} * 3.14 * 4^3\\\\V = 267.95 cm^3[/tex]

The volume of the sphere is [tex]267.95 cm^3[/tex]

And the probability that they cheated and we can use the classical definition of probability given by:

The solutions of a quadratic equation are 5 and -1. What is the factored form of a related quadratic function?

Answers

Answer:

f(x)=(x+1)(x-5)

Step-by-step explanation:

The solutions to a quadratic equation are going to be your x-intercepts, or when y is equal to zero. For y to be zero, all you have to do is have one value equal to zero. When x is 5, (x-5) is equal to zero. When x is -1, (x+1) is equal to zero. This is one example of what your quadratic equation could be.

Sydney is going to a carnival that has games and rides. Each game costs $1.25 and each ride costs $2.25. Sydney spent $24.25 altogether at the carnival and the number of rides she went on is 3 more than the number of games she played. Determine the number of games Sydney played and the number of rides Sydney went on.

Answers

Answer:

number of games played is 5

number of rides road 8

Step-by-step explanation:

8 x 2.25=18

5 x 1.25=6..25

18 + 6.25=24.25

The number of games Sydney played is 5 and the number of rides Sydney went on is 8.

What is linear equation?

Linear equation is the type of equation with highest power 1.

Assume the number games Sydney played be x. So, the number of rides she went is x+3.

The cost of 1 game is $1.25. So, the cost of x games will be 1.25x.

The cost of 1 ride is $2.25. So, the cost of x+3 rides will be 2.25(x+3).

The total cost is $24.25. Formulate the linear equation and solve it.

1.25x+2.25(x+3)=24.25

1.25x+2.25x+6.75=24.25

3.5x=17.5

x=5

Substitute x=5 into x+3.

5+3=8

Thus, the number of games Sydney played is 5 and the number of rides Sydney went on is 8.

What is simplification?

Using math and algebraic principles, simplification entails removing pointless variables, factors, or operations from an expression. Getting an expression that is simpler to use, manipulate, or solve is the aim. For example, simplifying an algebraic expression might involve combining like terms, factoring, or using the distributive property.

Here,
To simplify the given expression, we need to use the rules of exponents:

= [(x²y³)⁻¹ / (x⁻²y²z)²]²

= [(1 / x²y³) / (x⁻⁴y⁴z²)]²

= [(1 / x²y³) * (x⁴ / y⁴z²]²

= x⁴ / y¹⁴z⁴

Therefore, the exponent on x is 4, the exponent on y is 14, and the exponent on z is 4.

Probability that if a manta ray is spotted at random, it would be clouseau = Total number of Clouseau spotted each year) ÷(Total number of manta rays seen each year)

Step-by-step explanation:

The information given is not enough to determine the probability.

We need to know, how many Clouseau are seen each year, then we can find the desired probability.

The Parameters:

Total number of manta rays seen each year = 450

Probability that if a manta ray is spotted at random, it would be clouseau,

P = Total number of Clouseau spotted each year, C) ÷(Total number of manta rays seen each year, T)

2.) You and your friends buy ice cream cones at the local ice cream shop. The radius of the ice cream cone is 44 millimeters and the volume of the ice cream cone is 356,456.2136 cubic millimeters. What is the height of the ice cream cone?

Answers

Answer:

A. 525.42 inches^3

B. 175.91 mm

Step-by-step explanation:

a. Here we are asked to calculate the volume of the cone given the radius and the height of the cone.

Mathematically, the volume of the cone can be calculated using the formula below;

V = 1/3 * π * r^2 * h

where r is the radius which is 5.1 inches and h is the height of the megaphone = 19.3 inches

Plugging these values, we have;

V = 1/3 * 3.14 * 5.1^2 * 19.3 = 525.42 inches^3

b. Here we are tasked with calculating the height given the value of the volume and the radius.

mathematically, the formula to use is

V = 1/3 * π * r^2 * h

where V = 356,456.2136 cubic millimeter and r is 44mm

plugging these values we have

356,456.2136 = 1/3 * 3.14 * 44^2 * h

h =( 1,069,368.6408)/6,079.04

h = 175.91 mm
