Answer 1

Answer:

3

Step-by-step explanation:

Given expression:

[tex]\dfrac{(14^2-13^2)^{\frac{2}{3}}}{(15^2-12^2)^{\frac{1}{4}}}[/tex]

Following the order of operations, carry out the operations inside the parentheses first.

Apply the Difference of Two Square formula  [tex]x^2-y^2=\left(x+y\right)\left(x-y\right)[/tex]

to the operations inside the parentheses in both the numerator and denominator:

[tex]\implies \dfrac{((14+13)(14-13))^{\frac{2}{3}}}{((15+12)(15-12))^{\frac{1}{4}}}[/tex]

Carry out the operations inside the parentheses:

[tex]\implies \dfrac{((27)(1))^{\frac{2}{3}}}{((27)(3))^{\frac{1}{4}}}[/tex]

[tex]\implies \dfrac{(27)^{\frac{2}{3}}}{(81)^{\frac{1}{4}}}[/tex]

Carry out the prime factorization of 27 and 81.

Therefore, rewrite 27 as 3³ and 81 as 3⁴:

[tex]\implies \dfrac{(3^3)^{\frac{2}{3}}}{(3^4)^{\frac{1}{4}}}[/tex]

[tex]\textsf{Apply exponent rule} \quad (a^b)^c=a^{bc}:[/tex]

[tex]\implies \dfrac{3^{(3 \cdot \frac{2}{3})}}{3^{(4 \cdot \frac{1}{4})}}[/tex]

[tex]\implies \dfrac{3^2}{3^1}[/tex]

[tex]\textsf{Apply exponent rule} \quad \dfrac{a^b}{a^c}=a^{b-c}:[/tex]

[tex]\implies 3^{(2-1)}[/tex]

[tex]\implies 3^1[/tex]

[tex]\implies 3[/tex]

Answer 2

Given that,

→ ((14² - 13²)^⅔)/((15² - 12²)^¼)

Evaluating the problem,

→ ((14² - 13²)^⅔)/((15² - 12²)^¼)

→ ((196 - 169)^⅔)/((225 - 144)^¼)

→ (27^⅔)/(81^¼)

→ ((3³)^⅔)/((3⁴)^¼)

→ (3²)/3

→ 9/3 = 3

Therefore, the solution is 3.

Find the x - and y -intercepts of the graph of the linear equation -6x + 9y = -18

Someone else got x=(3,0) y=(0,-2) but it was wrong

Answers

Answer:

x-intercept = 3y-intercept = -2

Step-by-step explanation:

You want the intercepts of the equation -6x +9y = -18.

Intercepts

There are several ways to find the intercepts. In each case, the x-intercept is the value of x that satisfies the equation when y=0, and vice versa.

For y = 0, we find the x-intercept to be ...

  -6x + 0 = -18

  x = -18/-6 = 3

The x-intercept is 3; the point at that intercept is (3, 0).

For x = 0, we find the y-intercept to be ...

  0 +9y = -18

  y = -18/9 = -2

The y-intercept is -2; the point at that intercept is (0, -2).

Intercept form

The intercept form of the equation for a line is ...

  x/a +y/b = 1

where 'a' is the x-intercept, and 'b' is the y-intercept.

We can get this form by dividing the original equation by -18.

  -6x/-18 +9y/-18 = 1

  x/3 +y/(-2) = 1

The x-intercept is 3; the y-intercept is -2.

__

Additional comment

When asked for the intercepts, it is sometimes not clear whether you are being asked for the value where the curve crosses the axis, or whether you are being asked for the coordinates of the point there.

Your previous "wrong" answer was given as point coordinates. Apparently, just the value at the axis crossing is required.

You have to have some understanding of your answer-entry and answer-checking software to tell the required form of the answer (or you can ask your teacher).

The composition of functions

Answers

Answer: g(f(5)) = 352

Step-by-step explanation:

The question being asked is the same as finding g(f(5)).

What this means is to find f(5), and then plug that value into g(x) as x and solve.

f(5) = 4(5) + 1 = 20 + 1 = 21

g(f(5)) = g(21) = 21^2 - 4(21) - 5 = 441 - 84 - 5 = 357 - 5 = 352

Note: You could also find g(f(x)), and then plug 5 in as x and solve.

Start by plugging f(x) into g(x) such that you get g(x = f(x))

g(f(x)) = (4x + 1)^2 - 4(4x + 1) - 5

Now, replace x with 5 and solve to get g(f(5)).

g(f(5)) = (4(5) + 1)^2 - 4(4(5) + 1) - 5 = 352

Answers

To solve this problem, we can use the compound interest formula

[tex]A=P(1+\frac{r}{n})^{nt}[/tex]

Where A represents the accrued value, P represents the invested value, r represents the interest(in decimals), n represents the amount of times the interest is compounded per unit 't' and t represents the time.

Since the unit of the time 't' is years, and the interest is compounded yearly, n = 1.

To write a percentage as a decimal, we just have to divide the percentage value by 100.

[tex]3.6\%=0.036[/tex]

To find the amount of time t, we just have to subtract the year the money was invested from the year we want to know the money accrued.

[tex]t=2029-2011=18[/tex]

Then, using those values on the formula, we have

[tex]\begin{gathered} A=13,000(1+0.036)^6 \\ A=16073.1828298\ldots\approx16073.18 \end{gathered}[/tex]

The accrued value in the year 2029 will be $16,073.18.

The functions f(m) = 18 + 0.4m and g(m) = 11.2 + 0.54m give the lengths of two differentsprings in centimeters, as mass is added in grams, m, to each separately.

Answers

STEP - BY - STEP EXPLANATION

What to do?

Graph each equation on the same set of axis.

Determine the mass that makes the spring the same length.

Determine the length of that mass.

Write a sentence comparing the two springs.

Given:

f(m) = 18 + 0.4m and g(m) = 11.2 + 0.54m

Step 1

Find the x and y-intercept of both function.

f(m) = 18 + 0.4m

f(0) = 18+0.4(0) = 18

0 = 18 + 0.4m

0.4m = -18

m=-45

The x and y -intercept of the function f(m) are (0, 18) and (-45, 0) respectively.

g(m) = 11.2 + 0.54m

g(0) = 11.2 + 0.54(0)

g(0) = 11.2

0 = 11.2+ 0.54m

0.54m = -11.2

m=20.7

The x and y - intercepts are (0, 11.2) and (20.7, 0).

Step 2

Graph the function.

Below is the graph of the function.

Observe from the graph that that the mass that makes the spring the same length is approximately 48.5 grams.

The length at that point is 37.4 centimeters.

A large western state consists of 3593 million acres of land. Approximately 14% of this land is federally owned. Find the number of acres that are not federally owned.

Answers

The number of acres that are not federally owned = 3089.98 million

What do you mean by western state?

Land or other assets that are legally owned by the government or a government agency are referred to as government-owned property.

Federal, state, or local governments may be the owners of government-owned land, which may or may not be open to the general public without restriction.

If 14% of the land is federally owned, then 100 -14  = 86% of the land is not federally owned.

(14 *3593 ) / 100

50302 / 100 = 503.02

Federal owned land is 503.02 million acres of land.

3593 - 503.02 = 3089.98 =  (86× 3593) ÷ 100

Land not owned by Federal Government = 3089.98 million acres of land.

Answers

The probability that the sample mean will differ from the population mean by more than 1.8 mm = 0.9949

Given,

In the question:

According to the given problem the mean diameter μ= 149 mm (population mean) and the standard deviation is σ = 8mm

random sample size, n= 50 steel bolts is selected

Let the random variable that represents the diameter of steel bolts be denoted by x and from the problem we have x = 3.3mm

Let z = (x-μ) / (σ/√n ) ....(1)

using formula (1) and when the sample mean differs from the population mean by more than 1.8mm

z = (3.3 - 149) /(8/√50 )

⇒z = -2.575

The probability that the sample mean will differ from the population mean by more than 1.8 mm

P( z > -2575) = 1 - P(z< -2.575) = 1 - 0.0051 = 0.9949

[tex]\begin{gathered} \text{Ate 4}\frac{5}{12}\text{Plates of chocolate cupcakes} \\ \text{And} \\ \text{Ate 2}\frac{1}{3}\text{plates of cherry} \end{gathered}[/tex]

We are to add them together to know the total

[tex]4\frac{5}{12}+2\frac{1}{3}=6\frac{5+4}{12}=6\frac{9}{12}=6\frac{3}{4}[/tex]

The final answer

[tex]6\frac{3}{4}[/tex]

Find the equation of the linear function represented by the table below inslope-intercept form.xy1-3 -723-114-15

Answers

To find the linear equation, we use two points from the table (1, -3) and (3, -11). First, we have to find the slope with the following formula.

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

Where,

[tex]\begin{gathered} x_1=1 \\ x_2=3 \\ y_1=-3 \\ y_2=-11 \end{gathered}[/tex]

Let's those coordinates to find the slope.

[tex]\begin{gathered} m=\frac{-11-(-3)_{}}{3-1}=\frac{-11+3}{2}=\frac{-8}{2}=-4\to m=-4 \\ \end{gathered}[/tex]

The slope is -4.

Now, we use the point-slope formula to find the equation.

[tex]\begin{gathered} y-y_1=m(x-x_1) \\ y-(-3)=-4(x-1) \\ y+3=-4x+4 \end{gathered}[/tex]

Now, we solve for y to express it in slope-intercept form.

[tex]\begin{gathered} y+3=-4x+4 \\ y=-4x+4-3 \\ y=-4x+1 \end{gathered}[/tex]Therefore, the equation in slope-intercept form is y = -4x+1.

Steps Jeanne has a coupon for $1.95 off a jug of name-brand laundry detergent that normally costs $14.99. The store-brand laundry detergent costs $11.53. How much will Jeanne save if she buys the store-brand detergent instead of using her coupon and buying the name-brand?

Answers

we can do a subtraction to calculate the savings

[tex]14.99-11.53=3.46[/tex]

will save 3.46 buying store-brand laundry detergent

and your savings from using the coupon are 1.95

We make a subtraction between the savings to know how much you save more with one method than with the other

[tex]3.46-1.95=1.51[/tex]

she save $1.51 more buying store-brand
