Answers

Answer:

Use synthetic division to solve

Step-by-step explanation:

When dividing a polynomial by a zero, you first want to find the zero to divide by. Solving the zero (x+2) will give us the value of x to divide by. Subtracting 2 from each side gives us x=-2. Then, we write out the full polynomial. Since the only degrees that have numerical values are x^5 and 32, we substitute zero for the values in between (0x^4, 0x^3, 0x^2, and 0x). Then we follow the steps of synthetic division (as seen in the photo) to find our new values for our new equation.

1.Two cyclists are 7 miles apart when they begin biking away from each other in opposite directions. The speed of the first cyclist is 12 miles per hour. The speed of the second cyclist is b miles per hour greater than the speed of the first cyclist.

How many miles does the first cyclist bike in 45 minutes?

Answers

Answer:

9 miles

Step-by-step explanation:

If 1 hour is 12 miles, then 30 mins is 6 miles, then 15 minutes is 3 miles.

30+15=45

6+3=9

The first cyclist bikes 9 miles in 45 minutes.

Since two cyclists are 7 miles apart when they begin biking away from each other in opposite directions, and the speed of the first cyclist is 12 miles per hour, to determine how many miles does the first cyclist bike in 45 minutes the following calculation must be done:

60 = 12 45 = X 45 x 12/60 = X 540/60 = X 9 = X

Therefore, the first cyclist bikes 9 miles in 45 minutes.

many red marbles does she have?
A.8
B.12
C.16
D.24

Answers

Given:

Number of  blue marbles, twice as many red marbles as blue, and 8 yellow marbles.

She has a total of 32 marbles.

To find:

The number of red marbles.

Solution:

Let number of blue marbles be x.

Then, number of red marbles = 2x

Number of yellow marbles = 8

Total number of marbles = 32

[tex]x+2x+8=32[/tex]

[tex]3x=32-8[/tex]

[tex]3x=24[/tex]

[tex]x=8[/tex]

Now,

Number of red marbles [tex]=2(8)=16[/tex]

Therefore, there are 16 red marbles.

When = 3, what will the value for y be for the equation - 4x + 5y = 18?

Answers

If x equals 3 then y must equal 1.2

Answer: y=6

-4(3)+5y=18

-12+5y=18

add 12 to both sides

-12+5y+12=18+12

5y=18+12

5y=30

divide both sides by 5

5y÷5=30÷5

y=30÷5

y=6

Diego measured the length of a pen to be 22 cm. The actual length of the pen is 23 cm. Which of these is closest to the percent error for Diego’s measurement. Explain your choice. [3 point]
4.3%
4.5%
95.7%
104.5%

Answers

Answer: its either a or b

Error is the difference between the actual length of an object and its measured length.

The closest to the percent error for Diego's measurement is 4.3%

Step 1: Find the error

Error = Actual length - Measured length

= 23cm - 22cm

= 1 cm

Step 2: Find the percent error

Formula = Error/ Actual length × 100

= 1 /23 × 10

= 4.35%

Therefore, the closest to the percent error for Diego's measurement is 4.3%

A. 83

We can see that the Y value is less than 90 degrees or right angle. So we can cross out answer options C and D.

And we should know that all of the triangles add up to 180 degrees.

So the math would do is:

46+51=97

180-97=83

So...

The Y value is 83.

Yosemite Falls is the highest waterfall in North America and the fifth highest in the world. When viewed from the valley, it appears to be a single waterfall. However, it actually has three parts. The upper fall has the longest drop of 1430 feet. The middle cascade is 675 feet long, and the lower fall drops another 320 feet. What is the total length that the water falls?

Answers

Answer:

The water falls a total length of 2,425 feet

Step-by-step explanation:

In order to calculate the total length of the waterfall, we will find the sum of the three parts of the waterfall.

Length of upper fall = 1430 feet

Length of middle cascade = 675 feet

Length of lowe fall = 320 feet

Total length of fall = (Length of upper fall) + (Length of middle cascade) + (Length of lowe fall)

= 1430 + 675 + 320 = 2,425 feet

Total length that the water falls = 2,425 feet

The derivation of the quadratic function is true

What is Quadratic Equation?

A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.

The roots of the quadratic equations are

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

where ( b² - 4ac ) is the discriminant

when ( b² - 4ac ) is positive, we get two real solutions

when discriminant is zero we get just one real solution (both answers are the same)

when discriminant is negative we get a pair of complex solutions

Given data ,

Let the quadratic equation be represented as A

Now , the value of A is

ax² + bx + c = 0

Step 1 :

ax² + bx + c = 0

Step 2 : Subtracting c on both sides , we get

ax² + bx = -c

Step 3 : Divide by x on both sides , we get

ax + b = -c/x

Hence , the steps are true in solving the quadratic equation

Margie bought 1 1/2
pounds of tomatoes for $2.00 per pound,
1/4 pound of onions for $1.60 per pound, and 1 pound of apples for $1.65 per pound. How much did she pay for her total purchase?

Answers

Answer:

She spent $5.05 for her total purchase.

Step-by-step explanation:

First, you should convert the fractions into decimals to make it easier, which would make it, 1.5, .25, 1.

Second, multiply 1.5 by 2 because there are 1.5 pounds which are payed for $2.00. Do the others fractions corresponding with the number of pounds and the cost this same way. 1.5 multiplied by 2 is 3. .25 multiplied by 1.60 is 0.4, 1 multiplied by 1.65 is 1.65.

Lastly, Add it all up, 3+0.4+1.65=5.05
