Answer 1

Answer:

[tex]y=0.2*4^{x}[/tex]

Step-by-step explanation:

Notice when x increases 1, y is 4 times the previous one, so

the function is like [tex]y=C*4^{x}[/tex]

To determine the constant C, put any pair of (x, y)

Use x = 0, y = 0.2, so

0.2 = [tex]C*4^{0}[/tex] = C * 1 = C

then [tex]y=0.2*4^{x}[/tex]

Answer 2

Answer:

[tex]y=(0.2)4^x[/tex]

Step-by-step explanation:

General form of the exponential function: [tex]y=ab^x[/tex]

Substituting the first point (0, 0.2) into the function:

[tex]\implies 0.2=ab^0[/tex]

As any number to the zero power always gives one, [tex]b^0=1[/tex]

[tex]\implies0.2=a \times 1[/tex]

[tex]\implies a=0.2[/tex]

Therefore, [tex]y=(0.2)b^x[/tex]

Substituting the second point (1, 1.8) into the function:

[tex]\implies0.8=(0.2)b^1[/tex]

[tex]\implies0.8=(0.2)b[/tex]

[tex]\implies b=\frac{0.8}{0.2}[/tex]

[tex]\implies b=4[/tex]

So the final exponential equation is:

[tex]y=(0.2)4^x[/tex]

Checking the equation with the remaining two points:

[tex]x=2 \implies (0.2)4^2=3.2 \ \ \ \checkmark[/tex]

[tex]x=3 \implies (0.2)4^3=12.8 \ \ \ \checkmark[/tex]

Which of the following equations has both -5 and 5 as possible values of z?

z^2 =36

z^3 = 125

none of the above

Answers

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.

If the lateral surface area of a cylinder with height 4cm is 24pi cm squared then what is its volume?​

Answers

We are given –

Height of cylinder is = 4cmLateral surface area of cylinder is = 24πcm²

We are asked to find volume of the given cylinder.

Let the radius be "r".Then according to the question,it’s given –

[tex]\qquad[/tex] [tex]\pink{\twoheadrightarrow\bf Curved\: surface\: area _{(Cylinder)}= 2\pi r h }[/tex]

[tex]\qquad[/tex] [tex]\twoheadrightarrow\sf 2\pi r h = 24 \pi[/tex]

[tex]\qquad[/tex] [tex]\twoheadrightarrow\sf 2\cancel{\pi} rh = 24 \cancel{\pi}[/tex]

[tex]\qquad[/tex] [tex]\twoheadrightarrow\sf r =\dfrac{24}{2h}[/tex]

[tex]\qquad[/tex] [tex]\twoheadrightarrow\sf r = \dfrac{24}{2\times 4}[/tex]

[tex]\qquad[/tex] [tex]\twoheadrightarrow\sf r = \dfrac{24}{8}[/tex]

[tex]\qquad[/tex] [tex]\twoheadrightarrow\sf r = \cancel{\dfrac{24}{8}}[/tex]

[tex]\qquad[/tex] [tex]\pink{\twoheadrightarrow\bf r = 3 \: cm}[/tex]

Now, Let's find volume of cylinder

[tex]\qquad[/tex] [tex]\purple{\twoheadrightarrow\bf V_{(Cylinder)} = \pi {r}^{2}h}[/tex]

[tex]\qquad[/tex] [tex]\twoheadrightarrow\sf V_{(Cylinder)} = \pi \times 3^2\times 4 [/tex]

[tex]\qquad[/tex] [tex]\twoheadrightarrow\sf V_{(Cylinder)} = \pi \times 9 \times 4[/tex]

[tex]\qquad[/tex] [tex]\twoheadrightarrow\sf V_{(Cylinder)} = \pi \times 36[/tex]

[tex]\qquad[/tex] [tex]\purple{\twoheadrightarrow\bf V_{(Cylinder)} = 36 \pi \: cm^3}[/tex]

Henceforth, volume of cylinder is 36π cm³.

Step-by-step explanation:

Given :-

Height is = 4cmLateral surface area of cylinder is = 24πcm²

to find :-

volume of the given cylinder.

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

Volume = 113.04 cm³

What is the solution of the equation

Answers

Answer: x=-56/3 (the second answer)

We have the equation 3/4x + 5 = -9. Our goal is to isolate x. Firstly, we need to subtract both sides by 5. This gives us 3/4x = -14. Then, we need to multiply both sides by 4/3. This then gives us x = -56/3. Once that is simplified, this is -18 2/3.

The ratio of men to women working for a company is 7:5. If there are 192 employees total, how many women work for the company?

Answers

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

There are 54 women working for the company.

What is Ratio?

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.

The given graph is  a one-to-one function

What is a 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

What is the equation of the line parallel to

Answers

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
