Answer:

Option C

(4x + 5)(4x +5)

Step-by-step explanation:

Step 1: Write the expression

$16x^{2} + 40x + 25$

Step 2: Choose to integers that when you add you get 40 and when multiplied you get 400

The integers are +20 and +20

Step 2: Split 40x into + 20x nd + 20 x

Therefore

$16x^{2} + 40x + 25 = 16x^{2} + 20x + 20x + 25$

$16x^{2} + 20x + 20x + 25 = 4x(4x + 5) + 5(4x + 5)\\(4x + 5)(4x + 5)$

If f(x) = 4x-x², find<br> square root f(3/2)

katrin [286]

Answer:

$\frac{\sqrt{15} }{2}$

Step-by-step explanation:

$\sqrt{f(\frac{3}{2} )$ , substitute $\frac{3}{2}$ to x

$f(\frac{3}{2} )=4(\frac{3}{2} )-(\frac{3}{2} )^2$ = $\frac{15}{4}$ or 3.75

$\sqrt{f(\frac{3}{2} )$ = $\sqrt{3.75}$ = $\frac{\sqrt{15} }{2}$

The graph of Y = COS X+ż is the graph of the y = cos(x) shifted in which direction?

rjkz [21]

Answer:

2 units up

Step-by-step explanation:

You're just taking the entire graph of cos(x) and then adding 2 so it moves everything up. If you added 2 to x BEFORE taking the cosine

(like y = cos (x+2) ), then you would shift it left 2. Adding and subtracting from the x moves everything left or right. Adding or subtracting at the end just moves it up and down.
