Answer:

Well the answer would be 9.

Step-by-step explanation:

All you have to do is put 6 in the place of X. So the new equation would be 5x2+6-7, and all you do is solve that. So multiply 5 and 2 to get 10, than add 10 to 6 and get 16, 16 minus 7 to get your answer of 9.

What is Percentage Error?

The difference between an exact value and an approximation to it is the approximation error in a data value. Either an absolute error or a relative error might be used to describe this error.

Percentage error is the difference between the measured value and the true value , as a percentage of the true value

Percentage Error = [ ( | Measured Value - True Value | ) / True Value ]x 100

Given data ,

Weight of box of cookies = 24 ounces

Acceptable percentage error = 1.5 %

Maximum possible weight =
Weight of box of cookies + Acceptable percentage error  

Minimum possible weight =
Weight of box of cookies - Acceptable percentage error  

Maximum possible weight = 24 + ( 1.5/100 ) x 24

                                             = 24 + 0.36

                                             = 24.36 ounces

Minimum possible weight = 24 - ( 1.5/100 ) x 24

                                            = 24 - 0.36

                                            = 23.64 ounces

Therefore , difference of Maximum possible weight and Minimum possible weight will be

= 24.36 - 23.64

= 0.72 ounces

Hence , the difference of maximum possible weight and minimum possible weight will be 0.72 ounces

Answer:

richard is 22 and teo is 9

Step-by-step explanation:

Answer:

22 hours (B)

Step-by-step explanation:

John's velocity = 55mph

Sally's velocity = 65mph

John's time taken = x

Sally's time taken = x - 4

since they must cover the same distance.

and, distance = vel × time

Sally's vel × time = John's vel × time

55x = 65(x-4)

55x = 65x - 220

-10x = -220

x = 22 hours.

Therefore, Sally catches up after 22 hours

Answer: A

Step-by-step explanation: In all logic its only a 40 soemthing difference and its a bigger number so my guess is 6.1

The percentage decrease in the number of students will be 6.6%. The correct option is B.

The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Given that last year, Springfield Middle School had 620 students. This year, it has 582 students.

The percentage decrease will be calculated as:-

Percentage decrease = ( 620 - 582 ) / 582

Percentage decrease = ( 38 / 582) = 0.0652

Percentage decrease = 0.0652 x 100 = 6.52% ≅ 6.6%

Therefore, the percentage decrease in the number of students will be 6.6%. The correct option is B.

Answer:

the answer is 15. brainliest if correct..

Step-by-step explanation:

Answer: 15

Step-by-step explanation:

Answer:

1st one is "square root of 2x"

2nd one is "2 square root of x"

3rd one is "is not"

Step-by-step explanation:

1st one: you have 2x for g(x) then you plug that into the x for f(x) giving you square root of 2x

2nd one: you have  square root of x for f(x) then you plug that into the x for g(x) giving you 2 square root of x

3rd one: the inverse of the square root of x is x^2

The function [tex]\rm f(g(x)) = \sqrt{2x}[/tex] and the function [tex]\rm g(f(x)) =2\sqrt{x}[/tex] and the function f(x) is not the inverse of g(x) and this can be determined by using the given data.

Given :

The following steps can be used in order to determine the f(g(x)) and g(f(x)):

Step 1 - First write the given functions.

[tex]\rm f(x) = \sqrt{x}[/tex]

[tex]\rm g(x) = 2x[/tex]

Step 2 - Now, the function f(g(x)) is given by replacing x with g(x) in the function f(x).

[tex]\rm f(g(x)) = \sqrt{g(x)}[/tex]

Step 3 - Substitute the value of g(x) in the above expression.

[tex]\rm f(g(x)) = \sqrt{2x}[/tex]

Step 4 - Now, the function g(f(x)) is given by replacing x with f(x) in the function g(x).

[tex]\rm g(f(x)) =2f(x)[/tex]

Step 5 - Substitute the value of f(x) in the above expression.

[tex]\rm g(f(x)) =2\sqrt{x}[/tex]

Step 6 - The inverse of f(x) can be determined by replacing x by f(x) and f(x) by x.

[tex]\rm \sqrt{f(x)} = x[/tex]

[tex]\rm x^2 = f(x)[/tex]

Step 7 - Now, the inverse of g(x) is given by:

[tex]\rm 2g(x) = x[/tex]

[tex]\rm g(x) = \dfrac{x}{2}[/tex]

The function [tex]\rm f(g(x)) = \sqrt{2x}[/tex] and the function [tex]\rm g(f(x)) =2\sqrt{x}[/tex] and the function f(x) is not the inverse of g(x).

The question is missing parts. Here is the complete question.

The isosceles triangle below has height AQ of length 3 and base BC of length 2. A point P may be placed anywhere along the line segment AQ.

What is the minimum value of the sum of the lengths of AP, BP and CP?

Answer: The sum is 4.73.

Step-by-step explanation: Height of a triangle is a perpendicualr line linking a vertex and its opposite side.

Because triangle ABC is isosceles, point Q divides the base in 2 equal parts:

BQ = CQ = 1

Suppose QP = x

To calculate minimum value of the sum:

AP = AQ - QP

AP = 3 - x

Since triangles BQP and CQP are congruent and right triangles, use Pythagorean Theorem to figure out the value of BP and CP:

BP = CP = [tex]\sqrt{BQ^{2}+PQ^{2}}[/tex]

BP = [tex]\sqrt{1+x^{2}}[/tex]

Then, sum of AP, BP and CP is

[tex]f(x)=3-x+2\sqrt{1+x^{2}}[/tex]

The minimum value is calculated using first derivative:

[tex]f'=-1+\frac{2x}{\sqrt{x^{2}+1} }[/tex]

The value of x is limited: it can assume value of 0, when P=A and x=3, when P=Q. So, interval is [0,3].

x has value:

[tex]-1+\frac{2x}{\sqrt{x^{2}+1} }=0[/tex]

[tex]2x=\sqrt{x^{2}+1}[/tex]

[tex]4x^{2}-x^{2}-1=0[/tex]

[tex]3x^{2}=1[/tex]

x = ± [tex]\frac{1}{\sqrt{3} }[/tex]

x can't assume negative value because is not in the interval:

x = [tex]\frac{1}{\sqrt{3} }[/tex]

To find the minimum value of the sum, substitute x in the function above:

f([tex]\frac{1}{\sqrt{3} }[/tex])=[tex]3-\frac{1}{\sqrt{3} } +2\sqrt{1+(\frac{1}{\sqrt{3} })^{2} }[/tex]

[tex]f(\frac{1}{\sqrt{3}} )=3-\frac{1}{\sqrt{3}}+2(\sqrt{\frac{4}{3} } )[/tex]

[tex]f(\frac{1}{\sqrt{3}} )=3-\frac{1}{\sqrt{3}} +\frac{4}{\sqrt{3}}[/tex]

[tex]f(\frac{1}{\sqrt{3}} )=3+\frac{3}{\sqrt{3} }[/tex]

[tex]f(\frac{1}{\sqrt{3}} )=4.73[/tex]

The minimum value of the sum of AP, BP and CP is 4.73.

The minimum value of the sum of the lengths of AP, BP and CP is [tex]3 + \frac{\sqrt{3}}{3}[/tex] units.

According to this statement we must determine the sum of the line segment lengths so that a minimum is found. By Pythagorean theorem and given data we have the following expression:

[tex]y = AP + BP + CP[/tex]

[tex]y = 3-x +2\sqrt{x^{2}+1}[/tex] (1)

Now we proceed to find the critical values by performing first and second derivative tests.

FDT

[tex]-1 +\frac{2\cdot x}{\sqrt{x^{2}+1}} = 0[/tex]

[tex]2\cdot x = \sqrt{x^{2}+1}[/tex]

[tex]4\cdot x^{2}-x^{2}-1=0[/tex]

[tex]3\cdot x^{2} = 1[/tex]

[tex]x^{2} = \frac{1}{3}[/tex]

[tex]x = \frac{\sqrt{3}}{3}[/tex]

SDT

[tex]y'' = \frac{2\cdot \sqrt{x^{2}+1}-2\cdot x \cdot \left(\frac{2\cdot x}{\sqrt{x^{2}+1}} \right)}{x^{2}+1}[/tex]

[tex]y'' = \frac{2\cdot x^{2}+2-4\cdot x^{2}}{(x^{2}+1)^{3/2}}[/tex]

[tex]y'' = 2\cdot \frac{1-x^{2}}{(x^{2}+1)^{3/2}}[/tex]

[tex]y'' \approx 0.866[/tex]

A minimum exists when [tex]y'' > 0[/tex], then we conclude that [tex]x = \frac{\sqrt{3}}{3}[/tex] lead to a relative minimum. And by (1) we have the minimum sum:

[tex]y = 3-\frac{\sqrt{3}}{3}+2\sqrt{\frac{4}{3} }[/tex]

[tex]y = 3 - \frac{\sqrt{3}}{3} +\frac{4\sqrt{3}}{3}[/tex]

[tex]y = 3+\frac{\sqrt{3}}{3}[/tex]

The minimum value of the sum of the lengths of AP, BP and CP is [tex]3 + \frac{\sqrt{3}}{3}[/tex] units.

Nota - The statement reports typographical issues, the correct form is presented below:

Answer:

sin ∠FDE is 12/13

Step-by-step explanation:

The trigonometric ratios will be used to find the value of sin∠FDE

In the given triangle, according to angle FDE

Base = DE = 5

Hypotenuse = DF = 13

Perpendicular = EF = ?

sin ∠FDE = [tex]\frac{perpendicular}{Hypotenuse} = \frac{EF}{DF}[/tex]

We have to find the length of DF first

Pythagoras theorem will be used as the given triangle is a right angled triangle

[tex](Hypotenuse)^2 = (Base)^2+(perpendicular)^2\\(DF)^2 = (DE)^2+(EF)^2\\(13)^2 = (5)^2 + EF^2\\169 = 25+EF^2\\EF^2 = 169-25\\EF^2 = 144\\\sqrt{EF^2} = \sqrt{144}\\EF = 12[/tex]

So,

sin ∠FDE = EF/DF

sin ∠FDE = 12/13

Hence,

sin ∠FDE is 12/13

Subtract the time values

131.25 - 119.5 = 11.75

This rounds to 12 when rounding to the nearest whole number.

This means she ran about 12 minutes faster. Since she ran 12 miles, this tells us she ran about 12/12 = 1 minute faster per mile.

The more accurate amount is 11.75/12 = 0.97916666666667 and we can see this is fairly close to 1. If we round to the nearest whole number, then we would get 1.
