Which is a factor of the polynomial f(x) = 6x4 – 21x3 – 4x2 + 24x – 35?
2x – 7
2x + 7
3x – 7
3x + 7
Answer:
first option
Step-by-step explanation:
i just took the test on edge.
The factor of the polynomial [tex]f(x) = 6x^4 - 21x^3 - 4x^2 + 24x - 35[/tex] is (a) 2x - 7
The polynomial function is given as:
[tex]f(x) = 6x^4 - 21x^3 - 4x^2 + 24x - 35[/tex]
To determine if 2x - 7 is a factor, we start by setting it to 0
[tex]2x - 7 = 0[/tex]
Add 7 to both sides
[tex]2x = 7[/tex]
Divide both sides by 2
[tex]x =3.5[/tex]
Substitute 3.5 for x in f(x)
[tex]f(3.5) = 6(3.5)^4 - 21(3.5)^3 - 4(3.5)^2 + 24(3.5) - 35[/tex]
[tex]f(3.5) =0[/tex]
Because f(3.5) equals 0, then 2x - 7 is a factor of the polynomial

How to calculate the surface area of a figureThe composite figure is made up of a pyramid and prism
Surface area of pyramid = 2(13*9) + (10*9) + (10*12)
Surface area of pyramid = 234 + 90 +120
Surface area of pyramid = 444ft²
For the rectangular prism
Surface area = 2(11*9) + 2(10 * 11)
Surface area = 198 + 220
Surface area = 418ft²

Winston has just gone grocery shopping. The mean cost for each item in his bag was $3.24. He bought a total of 5 items, and the prices of 4 of those items are listed below:
$4.55,$2.53,$2.82,$4.66
Determine the price of the 5th item in his bag.
Answer:
$1.26
Step-by-step explanation:
total: 16.2 (3.24 * 5)
4.55 + 2.53 + 2.82 + 4.66 = 14.56
16.2 - 14.56 = 1.26
The price of the fifth item in W's bag is $1.55 if the mean price of all five items is $3.24.
A mean is one of the measures of central tendencies and is the average value of a group of observations. It is the ratio of the sum of all observations to the total number of observations.
The prices of the 4 items out of the 5 items W has bought are given as follows:
$4.55, $2.53, $2.82, $4.66
It is also given that the mean cost for each item is $3.24.
Let the price of the fifth item be x, then according to the question;
[tex]\dfrac{ 4.55+ 2.53+2.82+4.66+x}{5} = 3.24\\14.65 + x = 3.24 \times 5\\14.65 + x = 16.2\\x = 1.55[/tex]
Therefore, the price of the fifth item in the bag is $1.55.

What is the missing base of 9=____ to the power of 2?
Answer: 3
Step-by-step explanation:
Let x be the missing base. In this case, base to the power of 2 means this number x times itself will equal 9.
9 = [tex]x^{2}[/tex]
[tex]\sqrt{9}[/tex] = [tex]\sqrt{x^{2} }[/tex] [use square root to cancel the power of 2].
[tex]\sqrt{9}[/tex] = x
x = 3
Check: [tex]3^{2}[/tex] = 3 x 3 = 9
Find the rule to solve for N. X,5,6,n,10 Y,20,24,32,40
Answer:
Step-by-step explanation:
Consider what y values you are getting by letting x = 5 and then letting x = 6.
when x = 5 , y = 20
y = m*5
20 = m*5 Divide by 5
20/5 = m/5
4 = m
when x = 6 y = 24
y = mx
24 = m*6 Divide by 6
24/6 = m
m = 4
So now we can be sure of our solution for x when y = 32
y = m*n
32 = 4*n Divide both sides by 4
32/4 = 4*n/4
n = 8
Answer: n = 8

Answer:
C. y = 1/8x
D. y = x - 133
Step-by-step explanation:
In order to find the answer, you have to think about the answer choices
A. is saying that if you multiply 152 by 8, you will get 19 which is definitely not true
B. is saying that y is equal to 152/133 which is not true since 152/133= 8/7 which is some wacky decimal
C. would make sense because if you divide 152 and 8, you will get 19
Which makes the equation true because if you multiply 1/8 by 152/1, you get 152/8 which simplifies to 19 which satisfies the equation
D. This would also make sense since 152-133=19
So at the end, we can come to a conclusion that:
C. and D. are the equations that satisfy the relation
