Step-by-step explanation:

3 + 3 = 6

6 + 4 = 10

10 + 5 = 15

so...

15 + 6 = 21

Answer:

[tex]Y = 441[/tex]

Step-by-step explanation:

Given

M = 27 when Y = 16 and X = 9

Required

Find Y when M = 7 and X = 2

We start by getting the algebraic representation of the given statement

[tex]X^2 \alpha \frac{1}{\sqrt Y} \alpha M[/tex]

Convert the variation to an equation; we have

[tex]X^2 = \frac{KM}{\sqrt Y}[/tex]

Where K is the constant of variation;

When M = 27; Y = 16; X = 9, the expression becomes

[tex]9^2 = \frac{K * 27}{\sqrt{16}}[/tex]

This gives

[tex]81 = \frac{k * 27}{4}[/tex]

Make K the subject of formula

[tex]K = \frac{81* 4}{27}[/tex]

[tex]K = \frac{324}{27}[/tex]

[tex]K = 12[/tex]

Solving for Y when M = 7 and X = 2

Recall that [tex]X^2 = \frac{KM}{\sqrt Y}[/tex]

Substitute values for K, M and X

[tex]2^2 = \frac{12 * 7}{\sqrt{Y}}[/tex]

[tex]4 = \frac{84}{\sqrt{Y}}[/tex]

Take square of both sides

[tex]4^2 = (\frac{84}{\sqrt{Y}})^2[/tex]

[tex]16 = \frac{7056}{Y}[/tex]

Make  Y the subject of formula

[tex]Y = \frac{7056}{16}[/tex]

[tex]Y = 441[/tex]

Answer:

[tex]f^{-1}(x)=\sqrt[5]{\frac{x+11}{6}}[/tex]

Step-by-step explanation:

So we have the function:

[tex]f(x)=6x^5-11[/tex]

To find the inverse of a function, switch f(x) and x, change f(x) to f⁻¹(x), and solve for f⁻¹(x). So:

[tex]f(x)=6x^5-11\\x=6(f^{-1}(x))^5-11[/tex]

Add 11 to both sides:

[tex]x+11=6(f^{-1}(x))^5[/tex]

Divide both sides by 6:

[tex]\frac{x+11}{6}=f^{-1}(x)^5[/tex]

Take the fifth root of each side:

[tex]f^{-1}(x)=\sqrt[5]{\frac{x+11}{6}}[/tex]

And we're done :)

Answer:

Step-by-step explanation:

[tex]f(x)=6x^5-11\\[/tex]

Let y equal the equation

[tex]y =6x^5-11\\y+11=6x^5\\\\Divide\:both\:sides\:of\:the\:equation\:by \: 6\\\frac{y+11}{6} = \frac{6x^5}{6} \\\\\frac{y+11}{6} = x^5\\ \\Quatric\:root\:both\:sides\\\sqrt[5]{\frac{y+11}{6} } = \sqrt[5]{x^5} \\\\\sqrt[5]{\frac{y+11}{6} } = x\\\\f^-^1(x) = \sqrt[5]{\frac{x+11}{6} }[/tex]

Answer:

Step-by-step explanation:

Answer:

22

Step-by-step explanation:

Marissa has $4.40 quarter and dimes

she has 5 more quarters than dimes

that means she times

$4.40×5=22

Answer:

Dimes = 9 dimes.

Quarters = 14 quarters.

Step-by-step explanation:

Q = D + 5 (1)

25×Q + 10×D = 440. (2)

From eq(1) substitute the expression for Q into equation (2)

25×(D+5) + 10D = 440

25D + 125 + 10D = 440

35D = 440 - 125

35D = 315

D = 315/35

D = 9

so,

Dimes = 9 dimes.

and,

Quarters = 9+5

= 14 quarters.

25×Q + 10×D = 440

25×14 + 10×9 = 440

350 + 90 = 440

440 = 440

Answer:

[tex]S(r)=4\pi r^2[/tex].

Step-by-step explanation:

It is given that, the surface area S of a single-celled organism may be found by multiplying 4π times the square of the radius r of the cell.  

We need to express S as a function of r.

Let r be the radius of the cell and S(r) be the surface area of single-celled organism when radius is r.

According to the question,

[tex]S(r)=4\pi \times r^2[/tex]

[tex]S(r)=4\pi r^2[/tex]

Therefore, the required function is [tex]S(r)=4\pi r^2[/tex].

Step-by-step explanation:

Helix shape of the metal fitting parameterized :

C(t) = (cos(t), sin(t), t )

This shows that:  x = cos(t), y = sin(t), z = t

density of the metal can be represented as

f (x(t), y(t), z(t) = 2z = 2t

Use the distance formula to determine the distance between two points.

Answer:

2,844 ft, 713 ft, 481 ft, 55ft.

Step-by-step explanation:

New Mexico has the highest of the lowest land elevations of the given states, at 2,844 feet. It is followed by Idaho, at 713 feet, which is followed by Nevada, at 481 feet. Arkansas has the lowest land elevation at 55 feet. The elevations in order from highest to lowest are thus 2,844 feet, 713 feet, 481 feet, and 55 feet.

Answer:

2/7 or 2 over 7

Step-by-step explanation:

4/14 can be simplified. We know this because both 4 and 14 can be divided by 2. 4 divided by 2 = 2 and 1 divided by 2 = 7, thus the answer is 2 over 7.

Answer:

The confidence Interval = (0.329, 0.391)

Step-by-step explanation:

Formula for the Confidence Interval for proportion =

p ± z × √p(1 - p)/n

where

p = x/n

From the question

n = 900 people

x = 36% of 900 people

= 36/100 × 900

= 324

z = z score of 95% confidence Interval

z = 1.98

p = x/n

= 324/900

= 0.36

Confidence Interval = p ± z × √p(1 - p)/n

= 0.36 ± 1.96 × √0.36 (1 - 0.36)/900

= 0.36 ± 1.96 ×√0.36 (0.64)/900

= 0.36 ± 1.96 × √0.000256

= 0.36 ± 1.96 × 0.016

= 0.36 ± 0.03136

Confidence Interval = 0.36 ± 0.03136

= 0.36 - 0.03136

= 0.32864

Approximately to 3 decimal places = 0.329

= 0.36 + 0.03136

= 0.39136

Approximately to 3 decimal places = 0.391

Therefore, the 95% confidence interval for the population proportion of people who believe the governor broke campaign financing laws = (0.329, 0.391)

Answer:

A sinusoidal model would be used

The kind of function that have consistency in the periodic rate of change is the Average rate of changes

Step-by-step explanation:

The type of model that would be used is sinusoidal model and this is because there is periodic change in the values given ( i.e the rate of changes given )

For percentage rate of changes :

starting from 0.9% there is an increase to 1.3% then a decrease to 1.1% and a further decrease to 1% before an increase to 1.3% and another decrease to 1%

For Average rate of changes:

starting from 2.9 there is a decrease to 2.4, then an increase to 3.7 and another decrease to 3.1 followed by an increase to 3.6 and a decrease back to 3.2

This relation ( sinusoidal model ) is best suited for a linear model because there is a periodic rate of change in the functions

The kind of function that have consistency in the period rate of change is the Average rate of changes

Answer:

B. about 5 days.

Step-by-step explanation:

If you average;

400 miles per day

1990 miles trip would take?

Cross multiplying gives;

[tex]\frac{1990 * 1}{400}[/tex] = 4.975 days

Rounding off the answer to nearest day gives 5 days.

Hence the 1990 miles journey should take about 5 days.

A trip of 1990 miles would take around 5 days if you averaged 400 miles each day. Option B is correct.

It is described as the single number that embodies the mean value for the specified collection of data or the closed value for each item in the specified set of data.

It is given that, you averaged 400 miles per day,

We have to find the days would a trip of 1990 miles takes.

The number of days is obtained by taking the ratio of the total distance we have to travel to the distance traveled by the person in one day.

Suppose the number of days needed to complete the trip will be x,

x=Total distance/distance in one day

x=1990 / 400

x= 4.975 days

x≈5 days

If you averaged 400 miles each day, a trip of 1990 miles would take around 5 days.

Thus, option B is correct.

Answer:

Step-by-step explanation:

(x²+4)²-11(x²+4)+24=0

put x²+4=y

y²-11y+24=0

y²-3y-8y+24=0

y(y-3)-8(y-3)=0

(y-3)(y-8)=0

y=3,8

so x²+4=3

x²=-1=i²

x=±i

or x²+4=8

x²=4

x=±2
