Do you mean the hypotenuse of the triangle?

If so, you can use pythagorean theorem:

a^2 + b^2 = c^2

11^2 + 8^2 = c^2

121 + 64 = 185 = c^2

c = sqrt(185) = 13.6

17. MODELING WITH MATHEMATICS The data
Ksenya-84 [330]

Answer:

Average annual tuition is $16991 for the year 2020.

Step-by-step explanation:

By using excel for the equation of the line of best fit,

Slope of the line from given data = 380.0286

y - intercept of the line = 11290.1

Therefore, equation of the regression line will be,

y = 380.0286x + 11290.1

Where x = number of years after 2005

Now we have to calculate the average annual tuition in the  year 2020,

By substituting the value of x = 2020 - 2005

                                                 = 15 years

y = 380.0286×(15) + 11290.1

y = 16990.529

  ≈ 16991

Therefore, average annual tuition is $16991 for the year 2020.

Which of the following equations is the formula of f(x) = x^1/3 but shifted 4 units to the left and 4 units up?
nlexa [21]

Answer:

Hence correct chcie is C.

f\left(x\right)=(x+4)^{\frac{1}{3}}+4

Step-by-step explanation:

Given function is f\left(x\right)=x^{\frac{1}{3}}

Now it says that function is shifted 4 units to the left and 4 units up.

We need to find about which of the given choice is correct for the given transformation.

When f(x) is shifted "h" units left then we write f(x+h)

So f\left(x\right)=x^{\frac{1}{3}} will change to

f\left(x\right)=(x+4)^{\frac{1}{3}}

When f(x) is shifted "h" units up then we write f(x)+h

So f\left(x\right)=(x+4)^{\frac{1}{3}} will change to

f\left(x\right)=(x+4)^{\frac{1}{3}}+4
