Which Equation Could Generate The Curve In The Graph Below?
Answer 2

Answer:

[tex]y=-2x^2 -16x -28[/tex]

Step-by-step explanation:

We are given with the graph of a parabola

[tex]y=-2x^2 + 3x -5[/tex]

a=-2, b=3 and c=-5

Discriminant = [tex]b^2-4ac= 3^2 -4(-2)(-5)= 9-40= -31[/tex]

Discriminant is negative so x intercepts are imaginary.

In the graph we have two x intercepts.

[tex]y=-2x^2 -4x -2[/tex]

a=-2, b=-4 and c=-2

Discriminant = [tex]b^2-4ac= (-4)^2 -4(-2)(-2)=0[/tex]

Discriminant is 0 so there is only one x intercept

[tex]y=-2x^2 -16x -28[/tex]

a=-2, b=-16 and c=-28

Discriminant = [tex]b^2-4ac= (-16)^2 -4(-2)(-28)=32[/tex]

Discriminant is positive so there  are two x intercepts

[tex]x=\frac{-b+-\sqrt{b^2-4ac} }{2a} =\frac{16+-\sqrt{32} }{2(-2)}[/tex]

We will get two values for x

x= -5.414  , x=-2.586

Two x intercepts are negative . That is the x intercepts of given graph.

[tex]y=-2x^2 +16x -28[/tex]

a=-2, b=16 and c=-28

Discriminant = [tex]b^2-4ac= (16)^2 -4(-2)(-28)=32[/tex]

Discriminant is positive so there  are two x intercepts

(please help I am bad at math)

Answers

Answer:

128 ounces

Step-by-step explanation:

Mama Mia Restaurant used 1/2 of their mozzarella cheese.

Fraction of the cheese left = 1 - 1/2 = 1/2

Remaining Cheese = 64 ounces

1/2 of their cheese = 64 ounces

All of their cheese = 64 x 2 = 128 ounces

What is the perimeter of a square with a side length of 5(2p + 3)?

Answers

Answer:

P = 40p + 60

Step-by-step explanation:

The formula of a perimeter of a square withe side a:

P = 4a

We have a = 5(2p + 3).

Substitute:

P = 4[5(2p + 3)]               use the distributive property

P = 4[(5)(2p) + (5)(3)] = 4(10p + 15) = (4)(10p) + (4)(15)

Campbell's is designing a new label for their soup cans that covers the entire side of the can The soup can has a height of 8 inches and a radius of 2.5 inches. Determine how much material is needed to create each label.

Answers

Answer:

When π is approximated, 125.68, or 40π

Step-by-step explanation:

Circumference formula is 2πr

This is approx: 15.71

Multiply that by 8 to find the surface area of the side of the can.

The answer is 125.68.

HOWEVER, if you are expressing this without approximating π,

it would be 5(Pi), then multiply by 8, and we would get 40π

So un-simplified is 40π

Final answer:

The amount of material needed to create each label for Campbell's soup cans is 40π square inches.

Explanation:

To determine the amount of material needed to create each label for Campbell's soup cans, we need to find the lateral surface area of the can. The lateral surface area is the area of the curved surface. Assuming the label covers the entire side of the can, we need to find the area of the curved surface which can be calculated using the formula:

Lateral Surface Area = 2 * π * radius * height

Substituting the given values, we have:

Lateral Surface Area = 2 * π * 2.5 * 8 = 40π square inches.

The regular price of a television set is $1,200. Albert buys the television set at a discount of 35% . How much does he pay for the television set?​

Answers

He pays $780 for the television set.

1200*.35=420

1200-420=780

Albert pays $780 for the television set after receiving a 35% discount on the original price of $1,200.

The regular price of a television set is $1,200. To calculate the price Albert would pay after receiving a 35% discount, you need to calculate the discount amount and subtract it from the original price. The discount can be calculated by multiplying the original price by the discount percentage.

Discount = Original Price × Discount Percentage = $1,200 ×0.35 = $420

Now subtract the discount from the original price:

Final Price = Original Price - Discount = $1,200 - $420 = $780

Therefore, Albert pays $780 for the television set.

Step-by-step explanation:

Chef Katrina uses 1 cup of pecans for every 3 cups of peanuts in her Merry Munch Mix. One cup of pecans costs $ 4.99 and one cup of peanuts costs $2.25. If the cost for nuts in a batch of Merry Munch Mix is $35.22, how many cups of each type of nut were used?

Answers

Final answer:

Chef Katrina used 3 cups of pecans and 9 cups of peanuts for her Merry Munch Mix, totaling $35.22 based on the given prices of $4.99 per cup of pecans and $2.25 per cup of peanuts.

Explanation:

Calculating the Quantities of Pecans and Peanuts in the Merry Munch Mix

Chef Katrina uses a ratio of 1 cup of pecans to 3 cups of peanuts in her mix. We are given the cost per cup of pecans as $4.99 and the cost per cup of peanuts as $2.25. The total cost of nuts in the mix is $35.22.

To solve this, let's denote the number of cups of pecans used as p and the number of cups of peanuts as 3p (since there are three times as many peanuts as pecans). The total cost for pecans would be p times $4.99 and for peanuts 3p times $2.25.

Our equation based on the total cost is:
4.99p + 2.25(3p) = 35.22
4.99p + 6.75p = 35.22
11.74p = 35.22

Dividing both sides by 11.74 to solve for p:
p = 35.22 / 11.74
p = 3 cups of pecans

As there are three times more peanuts than pecans:
3p = 3 * 3 = 9 cups of peanuts

Therefore, Chef Katrina used 3 cups of pecans and 9 cups of peanuts in her Merry Munch Mix.

On a certain day, the temperature changed at a rate of -2 degrees Fahrenheit per hour. How long did it take for the change in temperature to be -14 degrees Fahrenheit

Answers

Answer:

7 hours.

Step-by-step explanation:

Pretty easy. 14 divided by 2. To check the answer, 2 x 7 = 14.

Final answer:

When the temperature change rate is -2 degrees Fahrenheit per hour, it takes 7 hours for the temperature to drop by -14 degrees Fahrenheit.

Explanation:

The question asks us to determine the time it took for the temperature to drop by -14 degrees Fahrenheit when the rate of temperature change was -2 degrees Fahrenheit per hour. This can be solved using a simple equation of rate × time = change in quantity. As the rate is -2 degrees Fahrenheit per hour and the total temperature drop is -14 degrees Fahrenheit, the equation becomes -2 × time = -14. To solve for time, divide the total temperature change by the rate of change. Substituting the values into the equation gives: time = -14 / -2. Thus, the time it took for the temperature to drop by -14 degrees Fahrenheit was 7 hours.

Normal Distributions are the most important in statistics. They are also know as "bell curves".

There are special properties of Normal Distributions. I name 3 of them below:

1. Normal distributions are symmetric about their mean.

2. The area under the normal curve is 1

3. The mean, mode, and median of normal distribution are equal

This question can easily be solved using property #3 in the stated above properties.

The mean and median of normal distribution are equal. Since mean is given as 22, the median will also be 22.

A and B are independent events . P(A) = 0.80 and P(B) = .10 what is P(A and B) ?

Answers

Answer:

The probability of A and B is:

                 [tex]P(A\ and\ B)=0.08[/tex]

Step-by-step explanation:

We know that when two events: Event A and event B are independent then if P denote the probability of an event then Probability A and B is equal to the product of probability of the individual events.

i.e.

[tex]P(A\ and\ B)=P(A)\times P(B)[/tex]

Here we have:

P(A) = 0.80 and P(B) = 0.10

Answer: Probability of guessing all 5 correctly: 1/3125 = 0.032%

Step-by-step explanation:

Probability of guessing the first question correctly:  1/5

For that 1/5 of the time when the first question has been guessed correctly, the second question could be guessed correctly 1/5 of the time. So the first two questions could be guessed correctly 1/5 × 1/5 = (1/5)^2 of the time.

Similarly the first three questions could be guessed correctly (1/5)^3 of the time.

and the first four, 1/5)^4 of the time;

and all fives,

(1/5)^5 of the time.

(1/5)^5 = 1/3125 = 0.00032 = 0.032%

what is the area of the figure:

Answers

For this case we have that the area of the triangle is given by:

[tex]A = \frac {b * h} {2}[/tex]

Where:

b: It's the base

h: It's the height

We have to:

[tex]cos (45) = \frac {b} {24}\\b = 24 * cos (45)\\b = \frac {\sqrt {2}} {2} * 24\\b = 12 \sqrt {2}[/tex]

The atura will be given by:

[tex]sin (45) = \frac {h} {24}\\h = 24 * sin (45)\\h = \frac {\sqrt {2}} {2} * 24\\h = 12 \sqrt {2}[/tex]

So, the area is:

[tex]A = \frac {12 \sqrt {2} * 12 \sqrt {2}} {2}\\A=\frac{(12\sqrt{2})^2}{2}\\A = 144[/tex]

Answer:

144

Answer:

Area=144

Step-by-step explanation:

In right triangle ABC,

[tex]\sin\left(45^o\right)=\frac{BC}{AB}[/tex]

[tex]\frac{1}{\sqrt{2}}=\frac{BC}{24}[/tex]

[tex]\frac{1}{\sqrt{2}}=\frac{Height}{24}[/tex]

[tex]\frac{24}{\sqrt{2}}=Height[/tex]

[tex]Height=\frac{24}{\sqrt{2}}[/tex]

similarly

[tex]\cos\left(45^o\right)=\frac{AC}{AB}[/tex]

[tex]\frac{1}{\sqrt{2}}=\frac{AC}{24}[/tex]

[tex]\frac{1}{\sqrt{2}}=\frac{Base}{24}[/tex]

[tex]\frac{24}{\sqrt{2}}=Base[/tex]

[tex]Base=\frac{24}{\sqrt{2}}[/tex]

Then area of right triangle [tex]=\frac{1}{2}\left(Base\right)\left(Height\right)[/tex]

[tex]=\frac{1}{2}\left(\frac{24}{\sqrt{2}}\right)\left(\frac{24}{\sqrt{2}}\right)[/tex]

[tex]=\frac{576}{4}=144[/tex]

Hence Area=144

Answers

The lowest common denominator of the two fractions is 4 because it is the smallest number that both fractions can be transformed into. 3/2 is multiplied by 2 to create 6/4 which can be added to 11/4.

we could add the left-side and then cross-multiply and so on, OR we can simply get the LCD of all denominators, in this case 4,2 so our LCD will just be 4, and multiply both sides by 4, that way doing away with the denominators, so let's do so

[tex]\bf 3d-\cfrac{11}{4}=\cfrac{3}{2}\implies \stackrel{\textit{multiplying both sides by }\stackrel{LCD}{4}}{4\left( 3d-\cfrac{11}{4} \right)=4\left( \cfrac{3}{2} \right)}\implies 12d-11=6 \\\\\\ 12d=17\implies d=\cfrac{17}{12}\implies d=1\frac{5}{12}[/tex]
