I got it right see

Answer:

The first one will be equal 2

Because

[tex] \frac{ - 64}{8} = - 8[/tex]

[tex]x ^{3} = 8 \\ [/tex]

[tex] \sqrt[3]{ - 8} = - 2[/tex]

Oh sorry i read the question wrongly i thought you wanted the value of x

main formula used

a³-b³=(a-b)(a²+ab+b²)

Answer:

[tex]y = \frac{3}{5}x - 2[/tex]

Step-by-step explanation:

First, find two points that are located on the given line. In this case, we will use the following points:

(-5 , -5) , (0 , -2)

First, find the slope. The slope can be found using the slope formula:

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

Let:

[tex](x_1 , y_1) = (0 , -2)\\(x_2 , y_2) = (-5 , -5)[/tex]

Plug in the corresponding numbers to the corresponding angles:

m = [tex]\frac{-5 - (-2)}{-5 - 0}[/tex]

Simplify. Combine like terms, and then divide:

m = [tex]\frac{-5 + 2}{-5 - 0} = \frac{-3}{-5} = \frac{3}{5}[/tex]

Plug in [tex]\frac{3}{5}[/tex] into the slope (m), and a point into (x , y) to find the y-intercept:

[tex]y = \frac{3}{5}x + b\\-2 = \frac{3}{5}(0) + b\\-2 = 0 + b\\-2 = b\\b = -2\\[/tex]

Your answer:

[tex]y = \frac{3}{5}x - 2[/tex]

Answer:

Step-by-step explanation:

It depends on what level you are. Logs are most easily developed by using a series for the natural logarithms (instead of base 10, you use base e). Even that is a difficult process using a series that you won't be introduced to until your second calculus course..

For now, I'd be content to use a calculator. The series does not converge terribly quickly.

Answer:

60, 120, 180, 240, 300, 360

Step-by-step explanation:

a(n)=60n

At n =1

a(1) = 60(1) = 60

At n = 2

a(2) = 60(2) = 120

At n = 3

a(3) = 60(3) = 180

At n = 4

a(4) = 60(4) = 240

At n = 5

a(5) = 60(5) = 300

At n = 6

a(6) = 60(6) = 360

60, 120, 180, 240, 300, 360

Answer:

For a function y = f(x), the domain is the set of the possible values of x that we can input, while the range is the set of the possible outputs of the function.

In this case we gave y = f(x) = (1/3)^x

A) Domain

To see the domain we always start assuming that the domain is the set of all real numbers, and then see if there is a real number that causes any problem.

(for example if we had a denominator like "x - 2", the point x = 2 would cause problems because it would make the denominator equal to zero, and we can not divide by zero)

Particularly because x is the exponent, we do not have any problem here, so the domain is the set of all real numbers:

D: = R

B) Range.

To find the range we usually need to find the smallest value of the function.

Here we have:

y = (1/3)^x

Is really easy to see that as x increases, the denominator increases but the numerator remains the same, then as x increases, the value of y decreases.

For example for x = 100 we will have:

y = 1/3^100 ≈ 0

(you also can see that y will never be a negative value, and as x increases the value of y tends to zero)

then:

0 < y

And if we have x negative, like x = -3 for example.

y = (1/3)^-3 = (3/1)^3 = 3^3 = 27

So if x decreases (or increases in the negative value) then the value of y increases, so we do not have any upper limit.

Then the range is only defined by

0 < y.

We can write the rane as:

R: (0, ∞)

C) The y-intercept is the value of y when x= 0

y = (1/3)^0 = 1

(for any number different than zero N, we have that N^0 = 1)

the y-intercept is 1

D) The asymptote is a tendency to a given value, such that the function never does reach that value.

Here we have two asymptotes.

y tends to infinity as x tends to negative infinity.

y tends to zero as x tends to infinity.

To find the coordinates of points A and B, go to Desmos and graph the given equation.

The word gradient means slope.

The slope is the coefficient of x in the equation. See it?

The gradient is 2.

Answer:

1095.2 cm² is correct (don't forget to say it's cm squared)

624.26 m² is correct                 (ditto)

I'm not 100% sure what the identity of the sets means, you're probably correct though

Step-by-step explanation:

area = 74 x 14.8 = 1095.2 cm²

radius = 28.2/2 = 14.1

area = 3.14(14.1²) = 624.26 m²

Answer:

5:04 pm

Step-by-step explanation:

The computation of the time does Jeremiah arrive at the grocery store is shown below:

She ate dinner at 6:17 pm

She took 25 minutes for cooking

She took 12 minutes to drive home from grocery store

And, the 36 minutes to the grocery store

So, the time at which she arrive is

= 6.17pm - 25 minutes - 12 minutes - 36 minutes

= 6.17pm - 73 minutes

= 5:04 pm

Answer:

Step-by-step explanation:

The central angle and the angle between the tangents are supplementary, so

x + 26° = 180° ( subtract 26° from both sides )

26 - 26 = 0

180 - 26 = 154

x = 154°

Answer: 154

Step-by-step explanation: 26 + x = 180, subtract 26 from both sides, x = 154

Answer:

A = 28.274ft^2

Step-by-step explanation:

Since we have the radius, we can find the area of the circle if it was a full circle.

[tex]A = \pi r^{2}[/tex]

Plug in the radius of 6 feet:

[tex]A = \pi 6^{2}[/tex] = [tex]113.09734[/tex]

With the area of the full circle, we can divide the area by 4 to get the area of a quarter of that circle.

[tex]113.09734 / 4 = 28.274335[/tex] or about [tex]28.274ft^{2}[/tex]

Answer:

I’m pretty sure it’s D

Step-by-step explanation:

A. Lets convert millimeters into kilometers.

[tex]1cm = 10mm \\ 10mm = 1cm \\ 10 \times 30 = 1 \times 30 \\ 300mm = 30cm \\ 30cm > 3cm[/tex]

since 4000000mm = 4km, A is true. (Not the answer)

B. Lets convert millimeters into centimeters.

[tex]1cm = 10mm \\ 10mm = 1cm \\ 10 \times 30 = 1 \times 30 \\ 300mm = 30cm \\ 30cm > 3cm[/tex]

Since 300mm > 3cm, B is true. (Not the answer)

C. Lets convert millimeters to meters.

[tex]1000mm = 1m \\ 1m = 1000mm \\ 1 \times 5 = 1000 \times 5 \\ 5m = 5000mm[/tex]

Since 5m = 5000mm, C is NOT true. (Answer)

D.Lets convert metres to kilometres.

[tex]1km = 1000m \\ 1 \times 2 = 1000 \times 2 \\ 2km = 2000m \\ 2km < 20km[/tex]

Since 2000m < 20km, D is true. (Not the Answer.)

Answer: 44g

Step-by-step explanation:

Half life refers to the length of time it takes for half of the atoms of the element in question to decay.

The half life here is 1 minute which means that in a minute, the amount of protactinium left would be:

= 352 / 2

= 176g

After the second minute:

= 176 / 2

= 88g

After the third minute:

= 88 / 2

= 44g

Answer:

x = -1/3 or x = -4

Step-by-step explanation:

Answer:

x= [tex]\frac{-1}{3}[/tex]

x= -4

Step-by-step explanation:

[tex]6x^2+28x-2=2x-10[/tex]

Subtract 2x - 10 from both sides.

[tex]6x^2+26x+8=0[/tex]

[tex]x= \frac{ -(26) +/ \sqrt{(26)^2-4(6)(8)} }{2(6)}[/tex]

x= [tex]\frac{-26 +/\sqrt{676-4(6)(8)} }{2(6)}[/tex]

x= [tex]\frac{-26 +/ \sqrt{676-192} }{2(6)}[/tex]

x= [tex]\frac{-26+/\sqrt{484} }{2(6)}[/tex]

x= [tex]\frac{-26+/22}{12}[/tex]

x= [tex]\frac{-26+22}{12}[/tex]  = -0.33333333333333 = -1/3

x= [tex]\frac{-26-22}{12}[/tex]= -4

The perimeter of the triangle is 34.2 units

To determine the value of the perimeter, we need to know the following;

The formula that is used for calculating the perimeter of a triangle is expressed as;

P = a + b+ c

Such that a , b and c are the lengths of the sides of the triangle

Then, we have that;

Using the Pythagorean theorem

a² =  81 + 121

a² = 202

a = √202 = 14.2 units

Perimeter = 9  + 11 + 14.2

Add the values

Perimeter = 34.2 units
