write the equation 12^-2 in simplest form

Answer:

The inverse of the function f(x) = 64x³ - 1 is [tex]\frac{\sqrt[3]{x+1}}{4}[/tex]

Step-by-step explanation:

First replace x with y.

[tex]x=64y^3-1[/tex]

Then solve for y.

[tex]y^3=\frac{x+1}{64}[/tex]

Cube root both sides.

[tex]y=\frac{\sqrt[3]{x+1}}{4}[/tex]

Hence, the inverse is [tex]\frac{\sqrt[3]{x+1}}{4}[/tex]

Answer:

Answer:

[tex]y=\frac{96}{x}[/tex]

Step-by-step explanation:

So when x and y, vary inversely, it means that the product of x and y will remain constant such that: [tex]xy=c[/tex]. This means that the function can be defined as [tex]y=\frac{c}{x}[/tex] by dividing both sides by x. In this case x=12, and y=8, this means the constant is equal to 12 * 8 which is 96. So we have the equation:  [tex]xy = 96[/tex], which can be defined as [tex]y=\frac{96}{x}[/tex]

If we make appropriate equation then we can find that there are 21 people and animals belong to the circus.

Given The number of acrobats and ballerinas, minus the number of clowns, is one fewer than the number of dogs. Double the combined number of acrobats and ballerinas is five more than three times the number of clowns.

We have to find total people and animals belong to the circus.

An equation is relationship between variables that are expressed in equal to form. It is solved to find the variables in equal to form Equations of two variables look like ax+ by=c.

let the number of acrobats be x, ballerinas be y, clowns be z, clowns be u.

According to given information in question the equations are:

x+ y-z=u-1-----------------------1

2(x+ y)=3z+5-------------------2

u=z+1----------------------------3

Put the value of u from 3 in 1

x+y- z=z+1-1

x+y-2z=0

from 2

z=2x+2y-5/3

put the value of z in x+y-2z=0

x+y-2(2x+2y-5/3)=0

-x-y+10=0

x+ y=10-------------------------4

put put the value of x+y=10 in 1

10-z=u-1

u+z=11-----------------------------5

solving 3

u-z=1------------------------6

Now add 5&6

u+z+u-z=11+12

2u=12

u=6

Put the value of u in 6

6-z=1

z=5

From above we get x+y=10, u=6, z=5

Add all three we get the total number of people and animals belong to circus.

x+y+u+z=10+6+5

=21

Hence there are total 21 people and animals belong to the circus.

[tex].95x = 85.50[/tex]

[tex]x = 90[/tex]

So the original price is $90. Divide this by 12, obtaining $7.50.

Answer:

a)$7.5

Step-by-step explanation:

Solution:

Let X represents socks

Given,

Selling price (SP) of 12x=$85.50

Discount precent (d%)=5%

So,

SP=(100-d)% of MP. [this formula really exist believe it or not]

85.50= (100-5)/100 ×MP

or, 85.50×100 =95×MP

or, 8550/95=MP

So,MP=$90

Now At last ,

cost of 1 shocks before discount is 90/12

which is $7.50 ans√

The two triangles in group A are similar because two angles of one are congruent to two angles of the other.

The two triangles in group A are similar because two angles of one are congruent to two angles of the other.

The two triangles in group B are not similar. The ratio of the short sides of the two triangles is 10:4 or 2.5:1, and that is the same ratio as the two sides 24 and 9.6.

However, using the fact that an angle bisector in a triangle divides the opposite side into two segments in the same ratio as the lengths of the two sides that include the angle, the length of the third side of the left triangle can be found to be about 25.12; and 9.25 times 2.5 is not close to 25.12.

b. In group A, the third side of the first triangle, by the Pythagorean Theorem, is sqrt(306).

The scale factor between the two triangles is 3:5, so the length of the third side of the second triangle is 15*(5/3) = 25.

In both triangles, the third angle measure is 31 degrees, since the sum of the three angles is 180.

c. The scale factor, again, is 3:5 which means the ratio of the areas of the two triangles is 3²:5² or 9:25.

d. The first triangle can be carried onto the second with the following transformations:

(1) dilate by a factor of 5/3 to make it the same size;

(2) rotate 90 degrees counterclockwise;

(3) translate so the hypotenuses of the two triangles are the same line segment; and

(4) reflect on the hypotenuse.

Step-by-step explanation:

The speed (rate) of the plane in still air is 1100 kilometers per hour and the speed (rate) of the wind is 210 kilometers per hour.

We assume the speed (rate) of the plane in still air to be x kilometers per hour, and the speed (rate) of the wind to be y kilometers per hour.

Thus, flying against the wind, the acting speed (rate) for the plane will be x - y kilometers per hour.

Flying with the wind, the acting speed (rate) for the plane will be x + y kilometers per hour.

We are given that flying against the wind, the airplane travels 6230 kilometers in 7 hours.

Thus, speed (rate) = 6230/7 kilometers per hour = 890 kilometers per hour.

Equating this to the derived speed of the airplane flying against the wind, we get x - y = 890 ... (i).

We are given that flying with the wind, the airplane travels 10480 kilometers in 8 hours.

Thus, speed (rate) = 10480/8 kilometers per hour = 1310 kilometers per hour.

Equating this to the derived speed of the airplane flying with the wind, we get x + y = 1310  ... (i).

Now, on adding equations (i) and (ii), we get:

2x = 2200,

or, x = 1100.

Substituting x = 1100 in (ii), we get:

x + y = 1310,

or, 1100 + y = 1310,

or, y = 1310 - 1100 = 210.

Thus, the speed (rate) of the plane in still air is 1100 kilometers per hour and the speed (rate) of the wind is 210 kilometers per hour.

If the top is 8 feet above the ground and ladder is 5 feet away from bottom of wall then the angle between ladder and house is 58°.

Given top is 8 feet above the ground, ladder is 5 feet away from bottom of the wall.

Trigonometric ratios are the ratios of the sides of a right angled triangle. sin is the ratio of perpendicular and hypotenuse , cos is the ratio of base and hypotenuse, tan is the ratio of perpendicular and base, cosec is the ratio of hypotenuse and perpendicular, sec is the ratio of hypotenuse and base, cot is the ratio of base and perpendicular.

Here we use tan d where d is the angle between ladder and wall of the house.

The correct answer is option B which is we need ∠L ≅ ∠R to prove congruency.

The Side-Angle-Side Congruence Theorem (SAS) defines two triangles to be congruent to each other if the included angle and two sides of one is congruent to the included angle and corresponding two sides of the other triangle.

According to the SAS theorem which means Side Angle Side, The angle which is included between the two sides must be congruent.

Here we are given that

KL = NR

JL = MR

Now in the figure, we can clearly see that the angle included between JL & KL is L & the angle included between NR & MR is R.

So for the triangles to be congruent by SAS, angle L must be congruent to angle R.

∠L=∠R

It's not an accurate value for the data based on the scatter plot, r = 0.01 is not an accurate value for this data, because 0.01 means practically no correlation, while the points on the graph are moderately correlated

1. Part A:

Since the points in the scatter plot shows a moderated upward trend, you must expect a correlation coefficient close to ± 0.5. A correlation coefficient of 0.01 is too close to 0, which would mean that the points are almost not correlated at all.

The correlation coefficients, r, measure the strength of the correlation of two variables and they can have values from - 1 to  1.

Here, r = - 1 is a perfect negative correlation as the points will adjust perfectly to a line with a negative slope.

r =  + 1 is a perfect positive correlation: the points will adjust perfectly to a line with a positive slope.

r = 0 means that the variables are not correlated at all.

Hence, the closer to zero, the worse the correlation is, and that is what r = 0.01 means, but the graph shows another thing.

Therefore, the calculated value of r = 0.01 is not accurate for this scatter plot.

2. Part B.

A causal relationship means that the explanatory variable (the independent variable) is the cause of the dependent variable.

        6.25                                                 320

Applying the vertical angles theorem, the measure of VU is determined as: 64°.

If two angles lie directly opposite each other, they are vertical nagles and are therefore equal.

13x = 15x - 8 [vertical angles theorem]

13x - 15x = - 8

-2x = -8

x = 4

Let y represent m(VU). Since m(RV) = m(VU), therefore:

13x + 2y = 180 [angles on a straight line]

Plug in the value of x

13(4) + 2y = 180

52 + 2y = 180

2y = 180 - 52

2y = 128
