The correct answer is z can take on the values of both -6 and 6, not -5 and 5.

The equation that has both -5 and 5 as possible values of z is:

[tex]z^2 = 36[/tex]

When we solve this equation, taking the square root of both sides, we get:

z = ±6

Therefore, z can take on the values of both -6 and 6, not -5 and 5.

Hence, none of the given equations have both -5 and 5 as possible values of z.For the equation z^2 = 36, we need to find the values of z that satisfy the equation. Taking the square root of both sides, we get:

z = ±√36

Simplifying the square root of 36, we have:

z = ±6

This means that z can take on the values of both -6 and 6. However, the values -5 and 5 are not solutions to this equation.

Similarly, for the equation z^3 = 125, there are no values of z that satisfy the equation for z equal to -5 or 5.

Therefore, none of the given equations, z^2 = 36 and z^3 = 125, have both -5 and 5 as possible values of z.

An exterior angle of a triangle is equal to the sum of the remote interior angles.

Solution :-

Lateral surface area of cylinder = 2πrh

24π cm = 2πrh

Cancelling π on both the sides ,

24/2h = r

putting the value of h i.e, 4 cm

24/2×4 cm = r

3 cm = radius

Now volume of Cylinder = πr²h

putting all the values ,

Volume = 3.14 × 3² × 4 cm³

Answer:

Cos of B = 36 / 38.884

Step-by-step explanation:

To find the cos of b you need the hypotenuse

(a)^2 + (b)^2 = (c)2

(36)^2 + (15)^2 = 1521

1521 squared is 38.884

Hypotenuse side goes on bottom and adjacent side on top

Cos of B = 36 / 38.884

Given, m<7 = 108°

To find, m<3

Since both the given angles are on the same side of transversal, thus there sum is 180°

Thus, m<7 + m<3 = 180°

108° + m<3 = 180°

m<3 = 180° - 108°

m<3 = 72°

Step-by-step explanation:

The given graph is  a one-to-one function

A relation is a function if it has only One y-value for each x-value.

A function is said to be one-one if corresponding to each x we get a distinct y-value.

i.e. No two x have the same y-value.

Also it can be seen from the graph when any horizontal line is drawn parallel to the x-axis then the line intersect the curve atmost once.

it passes the horizontal line test.

Many-to-one function is a function is many to one when many x-values are mapped to same y-value.

Clearly from the graph we see that the graph is a one-to-one function.

Hence, the given graph is  a one-to-one function

When it comes to exponents, I find it useful to remember that an exponent signifies repeated multiplication: x·x·x = x³. The exponent outside parentheses has the same meaning:

Seafloor spreading can be defined as a process that involves the formation of new oceanic crust as a result of volcanic activities and an upwelling of molten magma at mid-ocean ridges, as well as a slowly increasing distance (outward movement) from the ridge.

The theory of seafloor spreading was established by Harry Hammond Hess and it can be used to explain in details the slowly increasing distance between South America and Africa which grows from the center.

A hot spot refers to an area deep within Earth's mantle or under the rocky outermost layer of Earth, from which heat rises through convection and acquired as heat energy by a landform.

In the United States of America, you will see a layered sedimentary rock that is exposed by erosion when you view the Grand Canyon.

Furthermore, Australia is made up of relatively old and thick continental crust. Also, subduction causes the formation of extremely deep ocean Marianas Trench.

A regression can be modeled by linear regression, quadratic regression, quartic regression or exponential regression

The quadratic regression equation that models the data is

[tex]\^y = -0.875\^x^2 -3.596\^x +20.179[/tex]

The table entries are given as:

x: 0,1,2,3,4,5

y: 20,16,10,0,-7,-20

A quadratic regression is represented as:

[tex]\^y = a\^x^2 + b\^x + c[/tex]

Using a graphing calculator to determine the quadratic regression equation, we have the following calculation summary

a = -0.875

b = -3.596

c = 20.179

Hence, the quadratic regression equation is:

Answer:

y=3x-10

Step-by-step explanation:

A line parallel to another line has the same slope.

Therefore, we can create the equation y=3x+b.

Substituting (4,2) into y=3x+b,

2=3(4)+b

2=12+b

-10=b

y=3x-10

Therefore, the equation of the line parallel to y=3x-8 which passes through the point (4,2) is y=3x-10

Answer:

y = 3x - 10

Step-by-step explanation:

Equation: y = 3x + b

Point: (4, 2)

y = 3x + b

2 = 3 (4) + b

2 = 12 + b

b = -10

y = 3x - 10

7:5 mean that to every 7 men there is 5 woman.

There are 54 women working for the company.

The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.

The ratio of men to women working for the company is 7:5, which means that for every 7 men, there are 5 women.

We can express this as a fraction by writing 7/7 as 1 and 5/7 as 5/7, so the ratio becomes 1:5/7.

This fraction can be rewritten as 7/7:35/7, and since the two fractions have the same denominator, we can say that the ratio is equal to 7:35.

Since there are 192 total employees, and the ratio of men to women is 7:35, we can set up the following proportion:

7/35 = x/192

We can solve this proportion by cross-multiplying:

7/35 × 192 = x

This simplifies to:

x = 54

Therefore, the company hired 54 female employees.
