One factor of f (x ) = 5 x cubed 5 x squared minus 170 x 280 is (x 7). What are all the roots of the function? Use the Remainder Theorem. X = –4, x = –2, or x = 7 x = –7, x = 2, or x = 4 x = –7, x = 5, or x = 280 x = –280, x = –5, or x = 7.
Answers
To solve the problem we must know about the Remainder Theorem.
What is the Remainder theorem?According to the remainder theorem, when a polynomial P(x) is divided by (x-t) then the remainder of the division is equal to P(t). If P(t)=0, then the (x-t) is the factor of the polynomial.
The roots of the function are -7, 2, and 4.
Given to us
One factor of f (x) = [tex]5x^3+5x^2-170x+280[/tex] is (x +7).What is the quotient of the function?We know (x+7) is the factor of the function, f(x) = [tex]5x^3+5x^2-170x+280[/tex],
therefore,
[tex]f(x) =5x^3+5x^2-170x+280 = [(x+7) \times quotient] + Remainder[/tex]
As (x-2) is the factor of the function, therefore, the remainder will be zero for the equation,
[tex]\rm quotient=\dfrac{5x^3+5x^2-170x+280}{(x+7)}[/tex]
[tex]\rm quotient=5x^2-30x+40[/tex]
What are the factors of the function?Solving the quadratic equation,
[tex]5x^2-30x+40\\\text{Dividing the equation by 5}\\\\=x^2-6x+8\\=(x-2)(x-4)[/tex]
Hence, the roots of the function are -7, 2, and 4.

Sample 1: 10 boys and 10 girls
B
Sample 2: 10 boys and 35 girls
C
Sample 3: 6 boys and 7 girls
D
Sample 4: 7 boys and 6 girls
Answers
Answer:
C . Sample : 6 boy and 7 girls
Step-by-step explanation:

Boys = 150
Girls = 175
So ratio between boys and girls
175/150 = 1.67
So when boy is 6
6 ×1.667 = 7
A 12-V battery powers three lightbulbs in a series circuit. The voltage reading is 6 V across the first lightbulb and 3 V across the second lightbulb. What portion of the battery's energy transforms in the third lightbulb?
Please show how you got the answer!
Answers
Answer:
[tex]\displaystyle \frac{1}{4}[/tex].
Step-by-step explanation:
The voltage across the three bulbs would add up to [tex]12\; {\rm V}[/tex] since the three bulbs are connected in serial.
The voltage across the third bulb would thus be: [tex]12\; {\rm V} - 6\; {\rm V} - 3\; {\rm V} = 3\; {\rm V}[/tex].
Also because the three bulbs are connected in serial, the current going through each of them be the same as the size of the current of the whole circuit. Let [tex]I\; {\rm A}[/tex] be the size of that current.
The power supplied by the battery would be [tex]P = V \, I = 12\; {\rm V} \, (I\; {\rm A}) = (12\, I)\; {\rm W}[/tex].The power of the third bulb would be [tex]P = V\, I = 3\; {\rm V} \, (I\; {\rm A}) = (3\, I)\; {\rm W}[/tex].Thus, the portion of the power consumed by the third bulb would be [tex](3\, I) / (12\, I) = 1/4[/tex].
Rashad evaluated the power. (−2 10 )4 His value is 8 40. Is he correct? If not, what was his mistake? Yes, he is correct. No, his value should be negative. No, he multiplied the exponent by the base. No, he used the base as the exponent.
Answers
The evaluated result of the given number is 1/625 and not the 840 Thus the evaluated value of the Rashad is not correct, because he multiplied the exponent by the base.
What is the power rule of exponents?Power rule of exponents states that, when the two numbers with same base are multiplied then the exponents of both the numbers added.
Positive power of the negative number gives the positive result.
Given information-
The number which is evaluated by the Rashad is,
[tex](\dfrac{-2}{10})^4[/tex]
Let the evaluated result of the number is n. Thus,
[tex]n=(\dfrac{-2}{10})^4[/tex]
As the power is out of the bracket. This indicates that the power is for both numerator and denominator. Thus,
[tex]n=\dfrac{(-2)^4}{10^4}[/tex]
Positive power of the negative number gives the positive result. Thus the above equation can be written as,
[tex]n=\dfrac{2\times2\times2\times2}{10\times10\times10\times10}[/tex]
[tex]n=\dfrac{1}{625}[/tex]
As the evaluated result of the given number is 1/625 and not the 840 Thus the evaluated value of the Rashad is not correct, because he multiplied the exponent by the base.

nathan ordered one cheeseburger and one bag of chips for $3.75. jack ordered two cheeseburgers and three bags of chips for $8.25
Answers
Answer:
Cost of a bag of chips is $0.75
Cost of a cheeseburger is $3.
Step-by-step explanation:
[Step 1] Let the cost of a cheeseburger be x.
[Step 2] Let the cost of a bag of chips be y
[Step 3] As it is given that x + y = 3.75
[Step 4] It is also given that 2x + 3y = 8.25
[Step 5] Multiplying the equation in [Step 3] by 2 and we get 2x + 2y = 7.50
[Step 6] Subtracting the equation in [Step 5] from the equation in [Step 4] we get y = $0.75
[Step 7] Therefore the cost of a bag of chips is $0.75
[Step 8] Substituting the value of y found in [Step 7] into [Step 8] we get x = 3.
[Step 9] Therefore the cost of a cheeseburger is $3.
Check Answer:
Chip = 0.75
Cheeseburger = 3.00
Nathan Ordered one cheeseburger and one bag of chips for $3.75.
3.00 + 0.75 = $3.75
Hence, Chip = 0.75 and Cheeseburger = 3.00 is correct.
------------------------------------------------------------------------------------------------------
Chip = 0.75
Cheeseburger = 3.00
Jack Ordered two cheeseburger and three bags of chips for $8.25.
2 Cheeseburger = 3.00x2 = 6.00
3 bags of chips = 0.75x3= 2.25
6.00+2.25=$8.25
Hence, Chip = 0.75 and Cheeseburger = 3.00 is correct.

what is the probability of of selecting a lemon piece out of 6
Answers
Answer:
I'm assuming it's 1 lemon piece among 5 other pieces, if so then 1 out of 6.
Step-by-step explanation:
But In your case I “assume” there is 1 lemon out of 6 oranges for example.
So Out of 100% divided equally by 6. You’d have a 16.666666667 chance of picking any of the six. So because of this You’d have a 16% chance of getting a lemon out of a bin with 5 other things inside.
So your probability of getting a Lemon is Obviously a 1/6 with a 16% chance of getting a Lemon
Megan buys 2 new shirts for $16 each, crocs for $34, and a hat for $13. She bought the new clothes with a discount code of 15% off. How much did everything cost Lilah if there was also a 5% sales tax? (Round to the nearest hundredth)
Answers
Answer:
2 shirts - 16$ each
i.e. 32$
1 crocs pair - 34$
A hat - 13$
so the total she spent was,
16+16+34+13 = 79$
Now, if she is using 15% off in the total amount that will cost her => $11.85 !
since she is paying 5% sales tax so the final she paid is:

1) You want to put up a basketball hoop in your backyard, Regulation height for the basketball hoop is 10 feet
or 120 inches. After a couple of attempts at guessing the correct height and checking, you decide to use
shadows to estimate the height. You are 68 inches tall, and your shadow is 62 inches long. You are
standing 41 inches from the pole and the tip of your shadow coincides with the tip of the basketball hoop's
shadow as shown in the diagram below. To the nearest foot, what is the height of the basketball hoop?
SRT.1.2 (6 points)
Answers
By using the known relations for similar triangles, we will see that the height of the basketball hoop is H = 113 ft.
How to find the height of the basketball hoop?
In this situation, you and your shadow make a similar triangle to the one that makes the basketball hoop and its shadow.
This would mean that the quotients between the sides must be the same, so:
The quotient between your height and your shadow's length must be the same as the quotient between the hoop's height and its shadow's length.
Your height is 68 inYour shadow is 62 in long.You are at 41 in from the pole, and your shadow coincides with the shadow of the pole, so the length of the pole's shadow is:
41in + 62in = 103 in
And we define H as the height of the basketball hoop.
So we have that:
H/103in = 68in/62in
H = (68in/62in)*103in = 112.97 in
Rounding to the nearest foot, the height is 113ft.
