If f(x)=3x^5+2x^4+5, then what is the remainder when f(x) is divided by x−1?

Answers

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  

because a few extreme scores can create a deceptively large variation, the offers only a crude estimate of the variation in a data set.

Answers

Because a few extreme scores can create a deceptively large estimate of variation, the (B) range offers only a crude estimate of the variation in a data set.

What is a range?The range of a set of numbers is the difference between the highest and lowest values. Subtract the smallest number from the largest number in the set to calculate the range. To calculate the range, find the maximum observed value of a variable and subtract the minimum observed value (the minimum). The range only considers these two values and ignores the data points between the distribution's two extremes.Because a few extreme scores can produce an erroneously large estimate of variation, the range provides only a rough estimate of the variation in a data set.

Therefore, because a few extreme scores can create a deceptively large estimate of variation, the (B) range offers only a crude estimate of the variation in a data set.

Given the following functions, find and simplify (f. g)(5.5).
Provide your answer below:
(f-g)(5.5)=
f(x) = -x + 6
g(x) = -12x - 6

Answers

Answer:

78

Step-by-step explanation:

To compute (f.g)(5.5) , first compute g(5.5) , then use that value in f(x) to compute the composite function value

g(5.5) = -12(5.5) - 6 = -66 - 6 = -72

Use this value for x in f(x) = -x + 6

f(g(5.5)) = f(-72) = -(-72) + 6 = 72 + 6 = 78

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.

Find T given that the line segment joining:

(2,5) and (T, T) has gradient 4/7

Answers

Key ConceptsSolving for the slope/gradientSystems of equations

The slope (or gradient) can be solved by using this equation:

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

m = slope[tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] are two points that fall on the line

Solving the Question

We're given:

Line passes through (2,5) and (T,T)Gradient = [tex]\dfrac{4}{7}[/tex]

Plug all the given information into the equation above:

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}\\\\\dfrac{4}{7}=\dfrac{T-5}{T-2}[/tex]

This means that T - 5 must equal 4 and T - 2 must equal 7.

a semigroup which has a left identity element and in which every element has a right inverse is a group

Answers

Element and in which every element has a right inverse is a group?

Now, If both the identity and the inverse are of the same side, this is simple. For, instead of the above, say every element has a left inverse. For a∈G denote this left inverse by a−1.

Then(aa−1)(aa−1)=a(a−1a)a−1=aa−1

and we can use the fact that

cc=c

⟹c=1

to get that inverses are in fact two-sided: aa−1=1

From which it follows that

a=1⋅

a=(aa−1)a=a(a−1a)=a⋅

2x = 4

x = 2

The required number is 2 and

a. The equation is 2x + 6 = 10

b. The variable is x = 2

What are linear equation?

A linear equation only has one or two variables. No variables in a linear equation is raised to power greater than 1 or used as denominator of a fraction.

Let x be the number.

Now according to the given statement,

Six more than twice a number is 2x + 6

and it is 10.

So we can write
2x + 6 = 10

Substracting by 6 to the both side we get,

2x = 4

Dividing the equation by 2 we get

x = 2

Hence,The required number is 2 and

The range of the function y = |x + 1| + 3 is [3,∞)

what is Absolute value function?

A function that wraps an algebraic expression in absolute value symbols is known as an absolute value function. Remember that a number's distance from 0 on the number line represents its absolute value.

According to the given information:

The vertex of the function y = |x + 1| + 3

The function is given as:

y = |x + 1| + 3

The above function is an absolute value function

An absolute value function is represented as:

f(x) = a |x – h| + k

Where, the vertex is (h ,k)

So, we have:

(h ,k) = (-1,3)

Hence, the vertex of the function y = |x + 1| + 3 is (-1,3).

The range of the function y = |x + 1| + 3 is [3,∞)

Jamie is training for race and runs a 9 minute mile. She has cut a total 39 seconds off her time over the past 6 months. The situation can represented by the expression- 39 divided by 6. On average, how much time she cut off of her mile each month? Find the solution and explain what it means in the context of the problem.

Answers

1) On average, the time Jamie cut off her mile each month is 6.5 seconds.

2) In this context, the 6.5 seconds that Jamie cut off her mile each month means that she can finish a 9-minute-mile race by less than 6.5 seconds.

How is the average cut-off time determined?

The average cut-off time per month is determined by the mathematical operation of division.

Average refers to the mean of a data set divided by the number in the data set.

Data and Calculations:

The race Jamie is training for = a 9-minute mile

Cut-off time achieved in 6 months = 39 seconds

Period of training = 6 months

Average cut-off time = 6.5 seconds (39/6)

Time Jamie can finish the race = 8 minutes and 53.5 seconds (9 minutes - 6.5 seconds)

Thus, Jamie can complete the race in 8 minutes and 53.5 seconds if she maintains the average.
