Answer:

The correct option is: 11.5

Step-by-step explanation:

Suppose, the length of the unknown side is $x$

So, here the length of hypotenuse is 14 and the lengths of other two sides are 8 and $x$ .

As the given triangle is right angle triangle, so using Pythagorean theorem, we will get.........

$8^2+x^2= 14^2\\ \\ 64+x^2=196\\ \\ x^2=196-64=132\\ \\ x=\sqrt{132}=11.489...\approx 11.5$

(Rounded to the nearest tenth)

So, the length of the unknown side is 11.5

Simply the imaginary number square root -45

Paraphin [41]

Answer:

3i $\sqrt{5}$

Step-by-step explanation:

Using the rule of radicals

$\sqrt{a}$ × $\sqrt{b}$ ⇔ $\sqrt{ab}$

and $\sqrt{-1}$ = i

Given

$\sqrt{-45}$

= $\sqrt{9(5)(-1)}$

= $\sqrt{9}$ × $\sqrt{5}$ × $\sqrt{-1}$

= 3 × $\sqrt{5}$ × i

= 3i $\sqrt{5}$

When a new charter school opened in 1992, there were 440 students enrolled. Write a formula for the function N(t), representing

dsp73

Answer:

N(t) = m(X)+c

Step-by-step explanation:

Here, M is slope, also known as gradient, while X is the number which is variable and can keep on changing according to the number of increase, decrease or any other modification to the number of children in the school.

An finally, C is the constant which remains the same whatever the variable is. Therefore C would be equal to 440.

I hope this helps you.
