Answer:

$3\sqrt{5}$ units

Step-by-step explanation:

Use the Pythagorean Theorem to find the diagonal:

You have that the sides are 3 and 6, so a = 3 and b = 6, which means:

$3^2 + 6^2 = c^2\\9 + 36 = c^2\\45 = c^2\\c = 3\sqrt{5}$

fgiga [73]

Answer:

f(2) = 6

Step-by-step explanation:

Given that the function

$f(x) = \frac{x}{2} + 5$

Put x=2

What is the complete factorization of the polynomial below?<br> x3 + x2 + 9x+9

PIT_PIT [208]

Answer:

(x+1)(x-3i) (x+3i)

Step-by-step explanation:

x^3 + x^2 + 9x+9

We will use factor by grouping

Factor out x^2 from the first group and 9 from the second group

x^3 + x^2 + 9x+9

x^2( x+1) + 9(x+1)

Factor out (x+1)

(x+1) ((x^2+9)

Now factor x^2+9

x^2 -(3i)^2 = (x-3i) (x+3i)

Replacing this

(x+1)(x-3i) (x+3i)
