Answer:

Step-by-step explanation:

Cube Surface Area = 150 cm2

Cube Volume = ?

Ac = 6 a2

150 = 6a2

150/6 = a2

25 = a2

5 = a

-----------------------------------

Vc = a3

Vc = (5)3

Vc = 125 cm3

Answer:

Step-by-step explanation:

divide 150 by 6 and find the area of ​​one face of the cube, take the square root and find the side, side^3 and find the volume

150 : 6 = 25 cm² (area of ​​one face of the cube)

√25 = 5 (side of the cube)

5³ = 125 cm³ (volume of the cube)

The variable y represents the range or output values of the function.

The range of a function is the set of output values of the function.

The given equation is y = mx + b.

Note that x is an independent variable, therefore, we substitute the values for x and calculate the value of y to that value of x.

Therefore, y denotes the range or output values of the function.

The value of y' by implicit differentiation, the value of y is [tex]y = \sqrt{5x +c}[/tex]

We differentiate each side of an equation with two variables by taking one as a variable and the rest are constant.

Given

The function is [tex]y^2 + 5 = 5x[/tex]

where x and y are variables..

On differentiating the equation, we have;

[tex]2yy' + 0 = 5[/tex]

on simplifying, we have

2yy' = 5

Now solve the equation explicitly for y and differentiate to get y' in terms of x.

2yy' = 5

Separate the variables

[tex]y^2 = 5x + c[/tex]

Taking square root on both the side

[tex]y = \sqrt{5x +c}[/tex]

The equation that shows that angles angles formed by the diagonals and sides of the rhombus is x + y = z

The diagonals of rhombus intersect each other at 90 degrees

z =  angle formed at the diagonal = 90

x and y angle sides of the rhombus

applying the sum of angles of a triangle property

z + x + y = 180

where z = 90

90 + x + y = 180

x + y = 180 - 90

x+ y = 90

Tax compliance refers to policy actions and individual behavior aimed at ensuring that taxpayers are paying the right amount of tax at the right time and securing the correct tax allowances and tax reliefs.

Tax is defined as a mandatory financial charge or some other type of levy imposed on a taxpayer (an individual or legal entity) by a governmental organization in order to fund government spending and various public expenditures (regional, local, or national).

Step-by-step explanation:

The solutions to each of the given exponential functions are;

1) g = 1.356

2) u = 1.725

3) x = 3

4) k = -5.288

5)  a = 4/3

6) z = 1.295

7) x = 13/2

8) v = -1.5286

9) y = 4.17

10) b = 1.2648

Exponential equations are usually in the form a^(x) = b^(y) . To solve exponential equations with same base, we normally make use of the property of equality of exponential functions .

1) 7^(g) = 14

gIn 7 = In 14

g = In 14/In 7

g = 1.356

2) 6^(u) = 22

u In 6 = In 22

u = In 22/In 6

u = 1.725

3) 7^(x - 2) = 7

7^(x - 2) = 7¹

Equating the exponents gives;

x - 2 = 1

x = 3

4) (0.66)^k = 9

k In 0.66 = In 9

k = In 9/In 0.66

k = -5.288

5) Exponential equation 8^a = 16

2^(3a) = 2⁴

Equating the exponents gives;

3a = 4

a = 4/3

6) The exponential equation 12^z = 25;

z In 12 = In 25

z = In 25/In 12

z = 1.295

7) The exponential equation 4^(x-5) = 8

2^(2(x - 5)) = 2^(3)

2x - 10 = 3

2x = 13

x = 13/2

8) (0.28)^v = 7

vIn 0.28 = In 7

v = In 7/In 0.28

v = -1.5286

9) 2^y = 18

y In 2 = In 18

y = In 18/In 2

y = 4.17

If one plane can travel 10 miles per hour faster than another. The planes' speeds would be 435 miles per hour.

let s = speed of the slower plane

then

(s+10) = speed of the faster

495/s =510 /(s+10)

495s = 510s + 5100

Combine like terms

495 - 510s = 5100

The solution to the questions are:

From the question, we have the following parameters that can be used in our computation:

Length = 350 - 2x

Width = x

The area of a rectangle is the product of its dimensions

So, we have

Area = Length x Width

Substitute the known values in the above equation, so, we have the following representation

A = (350 - 2x) * x

Evaluate

A = 350x - 2x²

Differentiate and set to 0

350 - 4x = 0

So, we have

4x = 350

Divide by 4

x = 87.5

Recall that

Length = 350 - 2x

So, we have

Length = 350 - 2 x 87.5

Evaluate

Length = 175

The area is then calculated as

Area = Length x Width

So, we have

Area = 175 x 87.5

Evaluate

Area = 15312.5 square meters

Hence, the area is 15312.5 square meters

Given, two points (-5,0) and (-2,-3).

We are asked to find an equation of the line that passes through the given points.

As, we know

the equation of a line is

(y - y1)/(x - x1) = (y1 - y2)/(x1 - x2)

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

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

y/(x + 5) = -1

y = -(x + 5)

y = -x - 5

x + y + 5 = 0

[tex]\implies \sf \dfrac{2}{5}\;of\;1050=\dfrac{2}{5} \times 1050=420[/tex]

Therefore, Yadira's friend pays $420 for rent.

If the monthly utilities average is $365, Yadira's friend's portion of the utilities will be half of the total:
