ok!

to find mean, add all of the numbers, and divide that by how many numbers you have.

for example:

number 7 on your paper (8,9,10,15,28)

add those numbers together to get: 70

then divide 70 by 5 (since that's how many numbers there are in the problem) to get: 14

to get median write out all the numbers from least to greatest like you've done and find the middle number by marking off a number from the side each time then you will get: 10

to find mode you just write the number that appears the most. since there are no repeating numbers in your problem, theres no mode.

to find range you subtract the smallest number from the largest number in the problem.

so in your case, it would be 28-8

your range would be: 20

For a general quadratic equation, we want to find the equations for the vertex (h, k).

The values of the vertex are:

We start with the general quadratic equation:

f(x) = a*x^2 + b*x + c

To find the x-value of the vertex (h in this case) we need to find the zero of the first derivate of f(x) (because the vertex is a minimum/maximum of the function).

We have:

f'(x) = 2*a*x + b

We solve:

f'(h) = 0 = 2*a*h + b

        -b/(2*a) = h

So we just found the value of h.

To find the value of k, the y-value of the vertex, we need to evaluate the function in the x-value of the vertex, we will get:

k = f(h) = a*( -b/(2*a))^2 + b*( -b/(2*a)) + c

k = b^2/(4a) - b^2/(2a) + c

Then, concluding, we have:

Answer:

Slope = 2 and y-intercept = 8

Step-by-step explanation:

Use slope formula

m=y2-y1/x2-x1

m=16-12/4-2

m=4/2

Simplify

m=2

To find the y-intercept use point slope formula

y-y1=m(x-x1)

y-12=2(x-2)

y-12=2x-4

Add 12 to both sides

y=2x+8

So, 8 is the y-intercept or (0,8)

(3.) 2x^3-4x^2-x + (14/(x+6))

Step-by-step explanation:

The expression for the division of polynomials is obtained as  (2x³- 4x²- x) + 14/(x + 6).

The remainder theorem states that that when a polynomial p(x) is divided by another polynomial x + a, then the remainder obtained is given as the value of the polynomial at x = -a which is written as p(-a).

The given problem can be solved by remainder theorem as follows,

Suppose p(x) = 2x⁴ + 8x³- 25x²- 6x + 14.

Now, when p(x) is divided by x + 6, the remainder is given as,

p(-6) = 2 × -6⁴ + 8 × -6³ - 25 × -6² - 6 × -6 + 14

⇒ p(-6) = 14

Thus, by division lemma the following equation can be written as,

2x⁴ + 8x³- 25x²- 6x + 14 = (x + 6)(2x³- 4x²- x) + 14

⇒ (2x⁴ + 8x³- 25x²- 6x + 14) ÷ (x + 6) = (2x³- 4x²- x) + 14/(x + 6)

Hence, the equivalent expression is given as (2x³- 4x²- x) + 14/(x + 6).

Answer:

-4/5, -3/7, 1/4, 2/3

Step-by-step explanation:

The last one is the greatest as a positive but because it's both the greatest positive but a negative it is the smallest. Since 2/3 is closest to 1 and is positive it would be the greatest. -3/7 is a smaller value than 1/4 as it's closer to 0 than 1/4 is.

Answer: 150 + 3 = 150

Step-by-step explanation: The statue of liberty is approximately 150 feet tall from the base to the tip of the torch. A scale model is built that is 3 feet tall.

Step-by-step explanation:

1/3 mile in 12 minutes (=1/5 of an hour).

so, the speed (ratio of distance/time) is

1/3 mile / 12 minutes

the speed in mph is the converted ratio, where the denominator (bottom) is turned into 1 (hour).

what do I need to multiply 12 minutes with to get 1 hour ?

the same to multiply 1/5 with to get 1 : 5

to keep the overall value of the ratio the same I need to multiply both parts (top and bottom) of the fraction with the same value.

therefore,

1/3 / 12 × 5/5 = (1/3 × 5) / (12×5) = 5/3 / 60

so, the speed in mph is

5/3 miles / 60 minutes = 5/3 miles / 1 hour = 5/3 mph = 1 2/3 mph

D is the right answer.
