Step-by-step explanation:

f (-4)=(-4^2)-8 (-4)+8

f(-4)=54

The two points on the graph of the function are (2, -4) and (6, -4).

A polynomial function with one or more variables, where the largest exponent of the variable is two, is referred to as a quadratic function. In other terms, a "polynomial function of degree 2" is a quadratic function.

Given:

A quadratic function,

f(x) = x²−8x+8.

When f(x) = -4

That means,

quadratic equation,

x²−8x+8 = -4

x²−8x+12 = 0

x²−6x -2x + 12 = 0

x(x - 6) - 2(x - 6) = 0

x = 2 and x = 6

Therefore, the two points are (2, -4) and (6, -4).

Answer:

Cartesian Equation: y = √(1 - x^2)

Graph: Second one

Step-by-step explanation:

x^2 = sin^2(θ/2),

y^2 = cos^2(θ/2),

According to that theory, by the circle equation, x^2 + y^2 = 1^2.

When θ = -π, x = sin(-π/2) = - 1, and y = cos(-π/2) = 0

When θ = π, x = sin(π/2) = 1, and y = cos(π/2) = 0

The radius is 1 in this case, (x^2 + y^2 = r^2 -> x^2 + y^2 = 1^2 -> x^2 + y^2 = 1) as the semicircle ranges from (- 1, 0) to (1,0). Therefore your graph is the second one;

When theta = 0, x = sin 0 = 0, and y = cos 0 = 1, so the semicircle passes through (0, 1). To determine the equation, let's simply isolate "y" in the equation x^2 + y^2 = 1^2,

In Cartesian form, the equation is  y = √(1 - x^2)

Answer:

Yes. The vertical line never touches the graph at more than one point at the same time.

Step-by-step explanation:

this is the plato and edmentum answer

(make sure this is the right question)

As the vertical line touches the graph of the equation y = 2x - 3 it is a function.

The set of ordered pairings (x, y) where f(x) = y makes up the graph of a function.

These pairs are Cartesian coordinates of points in two-dimensional space and so constitute a subset of this plane in the general case when f(x) are real values.

Given, An equation y = 2x - 3.

Now, If we draw a vertical line and it touches the graph at only one point

the equation is a function but if the vertical line touches the graph at more than two points the equation is not a function.

Answer:

12.39km

Step-by-step explanation:

If Genevieve swam 590 meters for 3 weeks, then the equation is:

590 * 21

590 represents the number of meters Genevieve swam, and 21 is the number of days in 3 weeks.

Hope this helped!

Answer:

12.39 kilometers

Step-by-step explanation:

if she swan 590 meters each day, we know that there are 7 days in a week so multiply 7 by 3 and get 21 days. then multiply 590 by 21 and get 12390 meters. BUT the question is asking for kilometers so we are not done. from here we have to convert 12390 meters to ___ kilometers. to go from meters to kilometers divide by 1000 and we will get 12.39 kilometers.

Answer:

About $2.85 per gallon

Step-by-step explanation:

We can set up a proportion [tex]\frac{45.3}{15.9}[/tex]=[tex]\frac{x}{1}[/tex] we can then cross multiply, getting 15.9x=45.3. When you divide you get about $2.85

The slope means in this context, the draining of water is 3 gallons per minute. Then the slope of the line will be negative 3.

A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

The equation is given below.

y = −3x + 7, represents the amount of water y left in a 7-gallon tub after x minutes.

Then the slope of the line will be negative 3.

The slope means in this context, the draining of water is 3 gallons per minute.

Answer:

a. 0.41

b. 0.87

c. 0.13

Step-by-step explanation:

From the above question:

We are told that:

Probability that Jerry will not show up = 41% = 0.41

Probability that Jerry will show up =

100 - 41 = 59 = 0.59

Probability that Kramer will not show up = 31% = 0.31

Probability that Kramer will show up

= 100 - 31 = 69% = 0.69

Even though Jerry and Kramer know each other, their decisions can be assumed to be independent.

a. What is the probability that both Jerry and Kramer will show up? (Round your answer to 2 decimal places.)

= P(A) × P(B)

= Probability the Jerry will show up × Probability that Kramer will show up

= 0.69 × 0.59

= 0.4071

≈ 2 decimal places = 0.41

b. What is the probability that at least one of them will show up? (Round your answer to 2 decimal places.)

Probability = 1 - the probability that both Jerry and Kramer will not show up

= 1 - (0.41 × 0.31)

= 1 - 0.1271

= 0.8729

Approximately to 2 decimal places = 0.87

c. What is the probability that neither Jerry nor Kramer will show up? (Round your answer to 2 decimal places.)

Probability = Probability the Jerry will not show up × Probability that Kramer will not show up

= 0.41 × 0.31

= 0.1271

To 2 decimal places = 0.13

Answer: C |x – 45| = 3; minimum angle: 42 degrees

Step-by-step explanation:

The equation which can be used to determine the minimum and maximum optimal angles of launch and the minimum angle that is still optimal is |x – 45| = 3 and 42 degrees respectively.

This is formed when two straight lines meet at a common endpoint and are also formed during intersection of planes.

In this scenario we were told the angle is within 3 degrees of 45 degrees which means the minimum angle is 45 degrees - 3 degrees = 42 degrees with the equation used to determine the minimum and maximum being |x – 45| = 3 as the maximum angle and deviation has to be present in the equation.

Answer:

$5.99 for 1.5 lbs of gumballs

Step-by-step explanation:

You want to buy One and a half pounds of gumballs for $3.99 per pound. It is 3.99 for one pound of gumballs, so the price for half a pound of gumballs is half of that price.

3.99 / 2 = 1.995

Then add the price of 1 pound

3.99 + 1.995 = 5.985

Then you can round that up to 5.99

Answer:

Dylan owed a $1,264 fee, and earned $316

Step-by-step explanation:

First find out how much money he gets in 4 weeks without the fee

395 times 4 = $1,580

Then multiply 1,580 by the .2 percent he owes the eployment agency

$316

(He gets $316 for working for 4 weeks minus the fee) Subtract the payment without the fee by the payment with the fee to find out how much the fee was.

Dylan owe the employment agency $316

First we need to calculate the amount that Dylan will earn for the first 4 weeks. This will be:

= Weekly earnings × Number of weeks

= $395 × 4

= $1580

Since Dylan pays 20% to the employment agency, then the amount owed will be:

= 20% × $1580

= 0.2 × $1580

= $316

In conclusion, Dylan owe the employment agency $316.
