If f(x)=3x^5+2x^4+5, then what is the remainder when f(x) is divided by x−1?
Answer:
The remainder is 10
Step-by-step explanation:
The find the remainder when f(x) divided by g(x), find the value of x when g(x) = 0, then substitute it in f to find the value of the remainder
∵ f(x) = 3[tex]x^{5}[/tex] + 2[tex]x^{4}[/tex] + 5
∵ f(x) is divided by x - 1
∴ g(x) = x - 1
→ Equate g(x) by 0 to find x
∵ g(x) = 0
∴ x - 1 = 0
→ Add 1 to both sides
∵ x - 1 + 1 = 0 + 1
∴ x = 1
→ Substitute x in f by 1
∵ f(1) = 3[tex](1)^{5}[/tex] + 2[tex](1)^{4}[/tex] + 5
∴ f(1) = 3(1) + 2(1) + 5
∴ f(1) = 3 + 2 + 5
∴ f(1) = 10
∵ The remainder is the value of f(1)
∴ The remainder is 10

P(x)=2x ³+ x ²-7x-6
Answer:
x = -1.5, -1, 2.
Step-by-step explanation:
I am assuming you want to solve this>
Solve 2x ³ + x ² -7x - 6 = 0
It looks like x = -1 is a solution so we try it:
2*(-1)^3 + (-1)^2 -7(-1) - 6
= -2 + 1 + 7 - 6
= -1 + 1 = 0
So x = -1 is one root.
So (x + 1) must be a factor of P(x)
Now we divide by x + 1:
x + 1)2x ³ + x ² -7x - 6( 2x^2 - x - 6 <--- quotient
2x^3 + 2x^2
-x^2 - 7x
-x^2 - x
-6x - 6
-6x - 6
----------
2x^2 - x - 6 = 0
(2x + 3)(x - 2) = 0
x = -1.5, 2.

B.
(t − p)2(t2 − pt + p2)
C.
(t2 − p)(t4 + pt2 + p2)
D.
(t − p)2(t2 + pt + p2)
Answer:
(C). (t² - p)( [tex]t^{4}[/tex] + pt² + p²)
Step-by-step explanation:
a³ - b³ = (a - b)(a² + ab + b²)
[tex]t^{6}[/tex] - p³ = (t²)³ - p³ = (t² - p)( [tex]t^{4}[/tex] + pt² + p²)
If a pound costs $4.25, how much dose 0.46 pounds cost?
Answer:
$1.96
Step-by-step explanation:
Let's set up a proportion:
1 lb : $4.25 = 0.46 lb : $x
Here, x is the cost of 0.46 pounds. The ratio above can also be written in fraction form as:
[tex]\frac{1}{4.25} =\frac{0.46}{x}[/tex]
Now, we cross-multiply:
1 * x = 4.25 * 0.46
x = 1.955 ≈ $1.96

Reagan needs to sew a 1346 centimeters fringe around the edge of the bed spring.
Given that, Reagan has a rectangular bedspread that measures 238 centimeters by 435 centimeters.
What is the perimeter of a rectangle?The perimeter of a rectangle is the total distance of its outer boundary. It is twice the sum of its length and width and it is calculated with the help of the formula: Perimeter = 2(length + width).
Now, the perimeter = 2(238+435)
= 2×673
= 1346 centimeters
Therefore, Reagan needs to sew a 1346 centimeters fringe around the edge of the bed spring.

Answer:
x=6
MKL=37
Step-by-step explanation:
Answer:
Step-by-step explanation:
1. because U is between T and B
TU +UB = TB
2x+3x+1 =21
5x = 20
x= 4
mTU = 2x = 2*4 = 8
mUB = 3x+1 = 3*4 +1 = 12 +1 = 13
2.
m∠JKL = 59°
m∠MKL + m∠JKM = m∠JKL
5x+7 +2x+10 = 59
7x +17 = 59
7x = 59-17
x = 42/7 = 6
m∠MKL=5x+7 = 5*6 +7 = 30+7 = 37°

we conclude that:
[tex]\frac{2p}{4p^2-1}\div \frac{6p^3}{6p+3}=\frac{1}{2p^3-p^2}[/tex]
Step-by-step explanation:
Given the expression
[tex]\frac{2p}{4p^2-1}\div \frac{6p^3}{6p+3}[/tex]
[tex]\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{a}{b}\div \frac{c}{d}=\frac{a}{b}\times \frac{d}{c}[/tex]
[tex]=\frac{2p}{4p^2-1}\times \frac{6p+3}{6p^3}[/tex]
[tex]=\frac{2p}{4p^2-1}\times \frac{2p+1}{2p^3}[/tex]
[tex]\mathrm{Multiply\:fractions}:\quad \frac{a}{b}\times \frac{c}{d}=\frac{a\:\times \:c}{b\:\times \:d}[/tex]
[tex]=\frac{2p\left(2p+1\right)}{\left(4p^2-1\right)\times \:2p^3}[/tex]
cancel the common factor: 2
[tex]=\frac{p\left(2p+1\right)}{\left(4p^2-1\right)p^3}[/tex]
cancel the common factor: p
[tex]=\frac{2p+1}{p^2\left(4p^2-1\right)}[/tex]
[tex]=\frac{2p+1}{p^2\left(2p+1\right)\left(2p-1\right)}[/tex]
cancel the common factor: 2p+1
[tex]=\frac{1}{p^2\left(2p-1\right)}[/tex]
Expanding
[tex]=\frac{1}{2p^3-p^2}[/tex]
Thus, we conclude that:
[tex]\frac{2p}{4p^2-1}\div \frac{6p^3}{6p+3}=\frac{1}{2p^3-p^2}[/tex]

y+6=1/3(x-3) into standard form
Answer:
[tex]x-3y=21[/tex]
Step-by-step explanation:
The standard form of a linear equation is [tex]Ax+By=C[/tex]
STEP 1: Multiply both sides by [tex]3[/tex].
STEP 2: Simplify [tex]3(y+6).[/tex]
STEP 3: Simplify again.
STEP 4: Rewrite the equation with the sides flipped.
STEP 5: Move all terms containing variables to the left side of the equation.
STEP 6: Move all terms not containing a variable to the right side of the equation.
Rearranging the equation given to conform with the standard form of an equation, the expression becomes -x + 3y = - 21
The standard form of expression a linear equation is given as :
Ax + By = CGiven the expression : y + 6 = 1/3(x - 3)
Multiply both sides by 3
3(y + 6) = x - 3
3y + 18 = x - 3
Move x and y to the same side and the constant to the other.
3y - x = - 3 - 18
-x + 3y = - 21
Hence, the standard form of the equation is - x + 3y = - 21

A math test has 12 multiplication problems and 24 division problems.
What is the ratio value of multiplication problems to division problems?
Type your answer as a fraction in simplest form.
Answer:
12:24 = 1:2
Step-by-step explanation:
Since there are 12 multiplication problems, and 24 division problems, the ratio of multiplication and division problems are 12:24, now we need to put it in simplest form.
We need to find the highest number of which both are divisible by, 12 and 24 are both divisible by 12.
So 12÷12 = 1, and 24÷12 = 2, so 12:24 in simplest form is 1/2 or 1:2.
Answer:
1/2
Step-by-step explanation:
12 is half of 24. Therefore, the answer as a fraction in simplest form is 1/2.
