Which of the following functions best describes this graph?

A. y = (x - 3)(x + 1)
B. y = x - x +5
C. y = x? -5x + 6
D. y = (x - 1)(x - 1)

Answers

Answer: D: Y=(x-1)(x-1)

Step-by-step explanation:

The function described by the graph is [tex](x-1)^2[/tex].

Therefore, the correct answer is Option D. y = ( x - 1 ) ( x - 1 )

Given data:

The function is represented as f(x) = y

Now, the value of f(x) is plotted below:

To plot the graph, start by determining some key points and then connecting them.

When x = 0:

f(0) = 1

So, the point is (0, 1).

When x = 1:

f(1) = 0

So, the point is (1, 0).

When x = 2:

f(2) = 1

So, the point is (2, 1).

The graph of [tex]f(x) = (x - 1)^2[/tex]  is a parabola that opens upwards. The vertex of the parabola is at the point (1, 0), which corresponds to the minimum value of the function.

As x moves further away from 1 in either direction, the function increases.

Hence, the parabolic function is [tex]f(x) = (x - 1)^2[/tex].

The length of a rectangle is 3x-4 and the width is x. The perimeter is 72 feet. What is the measure of the length?

Answers

Answer : The length is 26ft

First, you would have to set an equation to find the value of x. To find this equation you would multiply both expressions for length and width by two. You would get the expression (6x-8) for length and the expression (2x) for width. You would then add these and make them equal to the perimeter, 72. You would get the equation 8x-8=72. Solving this equation would give you x=10. You just plug this value of x into the expression for length, which gives you the answer 26 ft.

Answer:

26 is your answer. I hope this helps!

Answer:

z's exponent = 5

Step-by-step explanation:

the degree of monomial is basically all of the exponents added up

so:

x's exponent + y's exponent + z's exponents = the degree

So:

1+2+z's exponent = 8

(since x to the power of 1 = x)

3+z's exponent = 8

Subtract 3 from each side:

z's exponent = 5

9.5=25/t+(-8) helppppppppp

Answers

Answer:

437.5

Step-by-step explanation:

I will REALLY answer your question :)

9.5 = 25/t + -8

The first step here is to simplify t + -8. If you add a negative of  something, you also subtract. This can be rewritten as:

9.5 = 25/t - 8

Now, we need to add 8 to undo the subtraction.

17.5 = 25/t

Now, to undo the division, we will multiply the whole equation by 25.

17.5 x 25 = 437.5

Point of Intersection:

Answers

Answer: (0; - 1)

Step-by-step explanation:

y = 5x - 1 and  5x = - 1 - y

                      y = - 1 - 5x

5x - 1 = - 1  - 5x

5x = -5x

5x + 5x = -5x + 5x

10x = 0

x = 0

y = 5x - 1

y = 5 × 0 - 1 = - 1

) Luci Lulu opened a cookie store in the mall. She found that the relationship between the price of a cookie, p, and the number of cookies sold, x, is given by the linear relationship x = −2000 p + 4000 . Find the maximum revenue Luci can make selling cookies in one day

Answers

Answer:

The maximum revenue Luci can make selling cookies in one day is $4,004,000.

Step-by-step explanation:

Given;

x = −2000 p + 4000 ..................... (1)

Revenue = xp

Revenue = (−2000 p + 4000)p =

Revenue = −2000p^2 + 4000p .................... (2)

The price at which Luci will the maximum profit can be calculated by finding the derivative of equation (2), equating to 0, and then solve for p as follows:

−4000p + 4000 = 0

4000 = 4000p

p = 4000 / 4000

p = 1

This implies that the price at which Luci will the maximum profit is $1.

Substituting p = 1 into equation (2) to obtain the maximum revenue Luci can make selling cookies in one day, we have:

Revenue = (−2000 * 1)^2 + (4000 * 1)

Revenue =  −2000^2 + 4000

Revenue = 4,000,000 + 4000

Revenue = 4,004,000

Therefore, the maximum revenue Luci can make selling cookies in one day is $4,004,000.

On Thursday, a local hamburger shop sold a combined total of 417 hamburgers and cheeseburgers. The
number of cheeseburgers sold was two times the number of hamburgers sold. How many hamburgers were
sold on Thursday?

Answers

Let H represent Hamburgers.  

Let cheeseburgers represent 2H .

H + 2H = 417

3H = 417

H = 417/3

H = 139 hamburgers  

2H = 2 * 139 = 278 cheeseburgers

Therefore, there were 139 hamburgers sold on Thursday.

Answers

Answer:

180 - 46 - 83 = 51 is the measure of angle C

the exterior angle at angle C, and angle C, are supplementary. since angle C is 51 because of the interior angle triangle sum theorem, then the exterior angle is: 180 -51 = 129 degrees.

A bag contains cards numbered from 1 to 14 one card is drawn at random find the probability of

a.) Selecting a prime number of a multiple of four

b.) selecting a multiple of two or a multiple of three

Answers

Answer:

One: P = 1/2 = 0.5

Two: P = 8/14 = 4/7 = 0.714

Step-by-step explanation:

One

I take it that the question is a prime number or 4.

P(four) = 1/14

The primes are 2,3,5,7,11,13. There are 6 of them

P(prime) = 6/14

P(prime or four) = 6/14 + 1/14 = 7/14 = 1/2

Two

Multiple of 2 := 2 4 6 8 10 12 14

Multiple of 3 :=  9 in addition to 6 and 12 which cannot be counted twice.

P(2 or 3) = 8/14 = 4/7 = 0.714
