Answer:

8x·x·x·x·x·x

Step-by-step explanation:

Using the rules of exponents, this simplifies to ...

[tex](2x^2)^3 = 2^3x^{2\cdot3}=8x^6=\boxed{8\cdot x\cdot x\cdot x\cdot x\cdot x\cdot x}[/tex]

The applicable rules of exponents are ...

(a^b)^c = a^(bc)

(ab)^c = (a^c)(b^c)

Of course, an exponent signifies repeated multiplication.

Determine the intercepts of the line.

Answers

x intercept is (5/2,0)
y intercept is (0,5)

Answer:

x: (5/2,0)

y: (0,5)

Step-by-step explanation:

To solve for x-intercept, substitute 0 for y.

-4x+7=2(0)-3

-4x+7=-3

-4x=-10

x=10/4 or 5/2

To solve for y-intercept, substitute 0 for x.

-4(0)+7=2y-3

7=2y-3

10=2y

The vertex of the parabola described by the equation 3y=2x^2-16x+18 is (m,n). What is m+n?

Answers

Answer:

the aswer is 32

Step-by-step explanation:

The vertex of the parabola described by the equation 3y=2x^2-16x+18 is (m,n). the sum of m + n is 178/27.

To find the vertex of the parabola described by the equation 3y = 2x^2 - 16x + 18, we first need to put the equation in the standard form of a parabola, which is y = a(x - h)^2 + k, where (h, k) represents the vertex.

Let's begin by dividing the entire equation by 3 to simplify it:

y = (2/3)x^2 - (16/3)x + 6

Now, we need to complete the square to rewrite the equation in the form y = a(x - h)^2 + k:

y = (2/3)(x^2 - (8/3)x) + 6

Next, we need to find the value that completes the square for the expression inside the parentheses. To do that, we take half of the coefficient of x and square it:

(8/3) / 2 = 4/3

(4/3)^2 = 16/9

Now, we add and subtract 16/9 inside the parentheses:

y = (2/3)(x^2 - (8/3)x + 16/9 - 16/9) + 6

Now, we group the first three terms and factor the perfect square trinomial:

y = (2/3)((x - 4/3)^2 - 16/9) + 6

Next, distribute the (2/3):

y = (2/3)(x - 4/3)^2 - (2/3)(16/9) + 6

Now, simplify:

y = (2/3)(x - 4/3)^2 - (32/27) + 6

Finally, bring everything together:

y = (2/3)(x - 4/3)^2 + (142/27)

Now we can see that the vertex of the parabola is at the point (h, k) = (4/3, 142/27).

To find m + n, we simply add the x-coordinate (h) and the y-coordinate (k):

m + n = 4/3 + 142/27

To add these fractions, we need to find a common denominator, which is 27. Convert 4/3 to have a denominator of 27:

4/3 = (4/3) * (9/9) = 36/27

Now we can add the fractions:

m + n = 36/27 + 142/27

m + n = (36 + 142)/27

m + n = 178/27

The length of the Titanic was 882 feet. Porter's history class is building a model of the Titanic. The model is 1/100 of the actual length of the ship. How long is the model?

Answers

Answer:

8.82 feet

Step-by-step explanation:

Explanation:

Let's set up the ratio. We know that the actual length of the ship was 882 feet and we want to know how long the model will be. We also have a ratio of 1 model length to every 100 actual length. So we can write this as:

Model length

Ship length

1 Model length

100 actual length

And we can drop in some numbers (I'll also put in the variable

to represent the length of the ship model):

882

100

Let's cross multiply to solve for x:

100

Distances in space are measured in light-years. The distance from Earth to a star is 4.1 × 1013 kilometers. What is the distance, in light-years, from Earth to the star (1 light-year = 9.46 × 1012 kilometers)? (5 points)

0.23 light-year

2.36 light-years

4.33 light-years

5.36 light-years

Answers

Answer:

5.36 light years

Step-by-step explanation:

if a light-year = 9.46 x 1012

9.46 x 1012 = 9512.8

4.1 x 1013 = 4153.3

After that you would subtract

9512.8 - 4152.3 = 5.360.5

the real answer is 5.36 light years

So the distance in light years from earth is 5.36 light years
