By factor theorem (v+5) is not a factor of the given polynomial f(v).
What does factor theorem mean?
When thoroughly factoring the polynomials, mathematicians apply the factor theorem. The polynomial's zeros and factors are connected by this theorem.
The factor theorem states that if a is any real number and f(x) is a polynomial of degree n 1 then (x-a) is a factor of f(x) if f(a)=0.
The factor theorem states that
f(x) has a factor (x-k) if and only if f(k) = 0
We are given the following information.
F(v) = v 4 + 16v 3 + 8v 2 - 725
We have to check whether (v+5) is a factor of given polynomial.
( v + 5 ) = ( v - ( - 5 )
f( -5 ) = [tex]( -5 )^{4} + 16( -5)^{3} + 8( -5)^{2} - 725[/tex]
= - 1900

Answer:
B. False
Step-by-step explanation:
You want to know if (x -2) is a factor of 5x² -6x +4.
RemainderThere are a couple of ways you can determine whether (x -2) is a factor. One is to look at the polynomial value at x=2:
5x² -6x +4 = (5x -6)x +4 = (5(2) -6)(2) +4 = 4(2) +4 = 12
The value is not 0, so (x -2) is not a factor.
Other factorAnother way to tell is to determine what the other factor would be.
The product of roots is the ratio c/a = 4/5 in the polynomial. If 2 is a root, then (4/5)/2 = 2/5 is the other root. That would mean the factorization of the polynomial is ...
(5x -2)(x -2) = 5x² -12x +4 . . . . . . not the same polynomial
The polynomial 5x² -6x +4 does not have a factor (x -2).
GraphThe graph of the polynomial has no x-intercepts, so (x -2) cannot be a factor.
Can you explain step by step how "a cube has a side length of 10 cm. The cube is dilated by a scale factor of 5. How does the volume of the new cube compare to the volume of the original cube?" The answer is the volume is 125 times the volume of the original cube but how is this the answer.
After the dilation, the new volume of the cube is 125 times the original volume of the cube.
How does the new volume compare to the original volume?Remember that for a cube of sidelength S, the volume is written as:
V = S^3
If we apply a dilation of scale factor 5 to the cube, then the new sidelength of the cube is 5*S
Replacing that in the volume formula we will get the volume of the dilated cube, it is:
V' = (5*S)^3
V' = 5^3*S^3
V' = 125*S^3
Where S^3 is the original volume, so we can write:
V' = 125*V
So the new volume is 125 times the original volume.

The function f(x) = e2x+1 when graphed could be described as:
a decreasing exponential graph.
an increasing exponential graph. an increasing linear graph.
None of these choices are correct.
The function ƒ(x) = e^(2x + 1) when graphed could be described as; an increasing exponential graph.
How to Interpret Exponential Graphs?The graphs of exponential functions are nonlinear—because their slopes are always changing, they look like curves, not straight lines.
Now, we are given the exponential function as; ƒ(x) = e^(2x + 1)
Now, as the exponent increases, the curves get steeper and the rate of growth increases respectively. Thus, we can see that the exponent we are given increases as seen in the exponent attached to it.
Thus, we can conclude that The function ƒ(x) = e^(2x + 1) when graphed could be described as; an increasing exponential graph.

(LOTS OF POINTS) The Sugar Sweet Company will choose from two companies to transport its sugar to market. The first company charges $5500 to rent trucks plus an additional fee of $175.50 for each ton of sugar. The second company charges $4995 to rent trucks plus an additional fee of $200.75 for each ton of sugar.
a) For what amount of sugar do the two companies charge the same?
b) What is the cost when the two companies charge the same?
The amount of sugar that both companies would charge the same is 20 tons.
The cost when the two companies would charge the same is $9010.
What is the amount of sugar that both companies would charge the same?The linear equation that represents the total charge of the companies : cost to rent truck + (ton of sugar x cost per ton)
The linear equation that represents the total charge of the first company : $5500 + ($175 x s)
$5500 + $175s
The linear equation that represents the total charge of the second company : $4995 + ($200.75 x s)
$4995 + $200.75s
When the two companies charge the same, the two linear functions above would be equal.
$4995 + $200.75s = $5500 + $175s
In order to determine the value of s, take the following steps:
200.75s - 175.50s = $5500 - $4995
25.25s = 505
s = 505 / 27.25
s = 20
In order to determine when the cost of the two companies would be the same, substitute for s in either of the above linear functions.
$5500 + $175.50(20)
$5,500 + 3510 = $9010

23.4 is what percent of 288? Round to the nearest tenth.
23.4 is 8.125 percentage of 288.
What are percentages?Percentage is defined as "out of 100." Similar to fractions and decimals, percentages are used in mathematics to represent subsets of a whole. When expressing a sum as a percentage, 100 equal components are regarded to make up the whole. A percentage can be shown by the symbol % or, less frequently, by the abbreviation 'pct'.
Calculation:1. Since 288 is the output value of the task, we assume that it is 100%.
2. We make the assumption that the value we are looking for is x.
3. If 100% = 288 then we can express that as 100% = 288.
4. Since we already know that the output result of x% equals 23.4, we can write it down as x%=23.4.
5. We now have two straightforward equations:
1) 100%=288
2) x%=23.4 where both of their right sides and left sides have the same units, allowing us to write something like this: 100%/x%=288/23.4
6. All that is left for us to do is solve the straightforward equation, and we will have our answer.
7. Calculate 23.4 as a percentage of 288.
100%/x%=288/23.4
We multiply both sides of the equation by x 100=12.307692307692 to get *x=(288/23.4)*x.
*x - we get x 100/12.307692307692=x 8.125=x by dividing both sides of the equation by (12.307692307692) to get x=8.125.
23.4 is 8.125 percentage of 288.

Answer:
biology = 255 ; sociology = 192
Step-by-step explanation:
b + s = 447
s = b - 63
b + b - 63 = 447
2b = 447 + 63
2b = 510
2/2 b = 510/2
b = 255
s = 255 - 63
s = 192
Answer: 192 sociology textbooks, 255 biology textbooks
Step-by-step explanation:
Let the number of biology be x, and the number of sociology be x
The number of the sociology textbook is x+63
So the equation is
x + x + 63 = 447
2x = 384
x= 192 sociology textbooks
To find the number of biology textbooks, just take 447- 192 = 255 biology textbooks

3. 3 = xy
4. b = 1/2a
5. y= 2/x
6. m = 5n
The equations, y=5x, b = 1/2 a, m=5n are direct variations.
What is direct variation?A sort of proportionality known as "direct variation" occurs when one quantity directly changes in response to a change in another quantity. This suggests that if one quantity increases, the other quantity will also increase proportionately. Similar to the last example, if one quantity declines, the other amount also declines. The link between direct variation and the graph will be linear, resulting in a straight line.
We know that any equation, which can be expressed in the form of y=kx, can be called a direct variation.
y = 5x is in the form of y = kx, where k =5, hence this is a direct variation
y = 2x + 1 is not in the form of y = kx, hence this is not a direct variation
xy = 3 is not in the form of y = kx, hence this is not a direct variation
b = 1/2 a is in the form of y = kx, where k =1/2, hence this is a direct variation
y = 2/x is not in the form of y = kx, hence this is not a direct variation
m = 5n is in the form of y = kx, where k =5, hence this is a direct variation
Thus, y=5x, b = 1/2 a, m=5n are direct variation
