The function f(x) is a quadratic function and the zeros of f(x) are - 2 and 5. The y-intercept of f(x) is 30. Write the equation of the quadratic polynomial in standard form.
f(x)=___________

Answers

Answer 1

Answer:

Step-by-step explanation:

First of all you have to put the zeros into factor form.

y1 = (x + 2)(x - 5)

Notice that the x changes sigh. You say that the zeros are -2 and  5. To get y1 to go to zero, you must make x the opposite sign of what you are given.

Now you have to expand the factored form to get the standard form

y = x^2 + 2x - 5x - 10

y = x^2 - 3x - 10

That's not the right answer.

f(0) = 30 but you have - 10 at the end so you have to multiply the factored form by - 3

-3(f(x)) = -3(x + 2)(x - 5)

-3(f(x)) = -3(x^2 - 3x - 10)

f(x) = -3x^2 + 9x + 30    

f(0) = -3(0)^2 + 9(0) + 30

f(0) = 30

The quadratic still has roots of (x +2)(x - 5) but that 3 makes the y intercept = 30.

See the graph below.

A bakery sells chocolate cupcakes and mocha cupcakes. One day it sold 153 chocolate
and 187 mocha. What percent of the cupcakes sold that day were chocolate?

Answers

Answer:

45% of the cupcakes baked on that day were chocolate flavored.

Step-by-step explanation:

Hey there!

We're given that the bakery sold 153 chocolate cupcakes and 187 mocha cupcakes.

Let's find the total number of cupcakes baked in a day.

[tex]153 + 187 = 340[/tex]

Now, we need to find the ratios of the cupcakes. Of the 340 cupcakes baked, 153 were chocolate flavored. Therefore, we can create a ratio between the two values and find the percentage.

Step 1: Define Values

153 chocolate cupcakes baked340 cupcakes in total

Step 2: Create Ratio and Simplify

[tex]\displaystyle \frac{\text{153 chocolate cupcakes}}{\text{340 total cupcakes}} = \frac{153}{340} = 0.45[/tex]

Step 3: Convert from Decimal Form to Percentage Form

[tex]0.45 \times 100\% = 45\%[/tex]

Therefore, we have determined that 45% of the cupcakes baked on that day were chocolate flavored.

The area of a rectangle is 560 square inches. The length is 3 more twice the width. Find the length and width.

Answers

Answer:

l = 35 inches and b = 16 inches

Step-by-step explanation:

Let length be b and width be b.

The area of a rectangle is 560 square inches.

Length is 3 more twice the width.

l = 2b+3 ....(1)

We know that,

Area = length × width

560 = (2b+3)b

[tex]2b^2+3b-560=0\\\\b=16,-17.5[/tex]

Put b = 16 in equation (1).

l = 2(16)+3

= 35 inches

So, the length is 35 inches and the width is 16 inches.

Mr. Martin had 7 eggs. He used half (½) of these eggs plus one-half (½) another egg to make an omelet. He then used half (½) of what was left plus half (½) another egg to make a batch of cookies. Finally, he used half (½) of what was left plus one-half (½) an egg to make a meatloaf.

Answers

Answer:

Number of eggs used to make meat loaf = 1

Step-by-step explanation:

The total number of eggs used to make omelet =

[tex]\frac{7}{2} + \frac{1}{2}\\\frac{8}{2} \\4[/tex]

The total number of eggs used for making cookies

[tex]\frac{3}{2} + \frac{1}{2} \\\frac{4}{2}\\2[/tex]

He is now left with 7 -4-2 = 1 egg only

So he uses this one egg to make meat loaf
