Answer:

C

6 and 7

Step-by-step explanation:

6) x^5y^7 / x^2y^3

= x^(5-2) * y^(7-3)

= x^3y^4

7) [tex]\sqrt[3]{300}[/tex]

= 6.69432..

OR you can try 6^3 and 7^3 values

216 343

as 300 is between 216 and 343

so \sqrt[3]{300} is between 6 and 7

so it is between 6 and 7

Answer:

Question 6 answer is: C and Question 7 answer is: A

Step-by-step explanation:

It's simple to divide for Question 6 because you just have to show the difference between the exponents. 5 - 2 = 3 and 7 - 3 = 4 so choice C is the best answer.

For question seven, the radical index is 3 so rewrite the equation as 300^(1/3). The answer will be around 6.69 which is between 6 and 7 so the answer is A.

Answer:

47.5 Meters

Step-by-step explanation:

Find where the derivative changes from positive to negative (local maximum)

h(t)=[tex]-6t^2+30t+10[/tex]

h'(t)=[tex]-12t+30[/tex]

Find where the derivative equals zero

Theres no spot where the derivative wont exist because its a polynomial.

-12t=-30

t=[tex]\frac{5}{2}[/tex]

Ill stop here because this is a parabola opening down and this is the only spot where there will be a horizontal tangent line so this is the x-coordinate of the vertex. AKA you don't need to test positive and negative on both sides.

Now plug into original equation

h(2.5)=[tex]-6(2.5)^2+30(2.5)+10[/tex]

=-37.5+75+10

=47.5

Answer:

1200.5

Step-by-step explanation:

Interest Rate = (Simple Interest × 100)/(Principal × Time).

I= 7000(.0245)(7)

I=1200.5

Answer:

1,200.5

Step-by-step explanation:

Simple interest is

I = Prt,

where I is the interest earn after t years, P is the initial money , r is the rate

I = 7000*.0245*7 = 1,200.5

1,200.5 is the interest after 7 years

Step-by-step explanation:

7/8 divided by 1/4

7/8 x 4/1 =7/2 = 3/1/2

Three and a half bags

Step-by-step explanation:

Use the equation

[tex] \frac{x - x1}{y - y1} = m[/tex]

So plug in the numbers

[tex] \frac{ 2 + 2}{3 - 4} = \frac{4}{ - 1} = - 4[/tex]

So if y=mx+b and there is no intercept the equation would be

[tex]y = - 4x[/tex]

The remaining zero of polynomial is (5 + i).

And, the linear factorization of the polynomial are;

(x - 2) (x - (5-i)) (x - (5 + i)).

What is Zeros of polynomial?

Zeroes of a polynomial are the points where the polynomial becomes zero.

Given that;

Zeroes of the polynomial are 2, 5 - i

Now, If one zero of polynomial is complex then another zero of the polynomial is its conjugate.

So, One root of polynomial = 5 - i

Then, The third zero of the polynomial = 5 + i

Thus, The polynomial are find as;

(x - 2) (x - (5-i)) (x - (5 + i)) = 0

So, The remaining zero of polynomial is (5 + i).

And, the linear factorization of the polynomial are;

(x - 2) (x - (5-i)) (x - (5 + i)).

Answer:

m=2

Step-by-step explanation:

you subtract the y-values (4-2) and put it as the numerator of a fraction than subtract the x-values (3-2) and put them as the denominator of the fraction. For this equation it would be

[tex]\frac{4-2}{3-2} = \frac{2}{1} = 2[/tex]

Answer:

The answer is B) 432

Step-by-step explanation:

The 4 in 432 becomes a 3, because we can't subtract 6 from 3. The 3 becomes 13 and if we subtract 13 with 6... We get 7.

I got 0 with option B... With A I got 2 which is a remainder. With C I got 6.5 (repeating). And with D I got 7.77777777778.

Hence, B) 432 is the correct option.

Check screenshot of my work below.

(I forgot to include 48 on top of the division I just did. Don't mind that too much..)

A) 326

[tex] \frac{326}{9} [/tex]

[tex] = 36.2222222222 [/tex]

B) 432

[tex] \frac{432}{9} [/tex]

[tex] = 59[/tex]

D) 630

Answer:

k =1

Step-by-step explanation:

3x + y = -7

      y = -3x - 7

m = -3

Parallel lines have same slope

[tex]Slope = -3\\\\\dfrac{8-[-1]}{-2-k}=-3\\\\\\\dfrac{8+1}{-2-k}=-3\\\\\dfrac{9}{-2-k} = -3[/tex]

Cross multiply,

9 = -3(-2-k)

9 = 6 + 3k

9-6 = 3k

3 = 3k

3/3 = k

k = 1

(1/3)^4 = 1^4/ 3^4 = 1/81

Answer: 1/81

The expression 1/3 by the power of 4  when evaluated has a value of 1/81

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

1/3 by the power of 4

Express as an equation

So, we have

1/3 by the power of 4 = 1/3⁴

When expanded, we have

1/3 by the power of 4 = 1/3 * 1/3 * 1/3 * 1/3

Evaluate the products

This gives

1/3 by the power of 4 = 1/81

Hence, the solution is 1/81

Answer:

Infinitely Many Solutions

Step-by-step explanation:

They are the same line so they cross each other infinitely many times.

If you picked a point on the first equation it would be the same point on the second equation.

Answer:

D) Infinitely many solutions

Step-by-step explanation:

Given the follwowing systems of linear equations, y = x + 2, and -3x + 3y = 6:

Transforming -3x + 3y = 6 into its slope-intercept form, y = mx + b:

-3x + 3y = 6

Add 3x to both sides:

-3x + 3x + 3y = 3x + 6

3y = 3x + 6

Divide both sides by 3:

[tex]\frac{3y}{3} = \frac{3x + 6}{3}[/tex]

y =  x + 2     ⇒ This is the slope-intercept form of -3x + 3y = 6.  Since they are equivalent equations, then it means that their graphed lines coincide. Since any point on either lines coincide (or also exists) on the other line, then it means that the solutions to one of the equations will satisfy the other. Therefore, the given systems of linear equations have an infinitely many solutions.
