H(x) = (x2 − 49)(x + 4)

Maru [420]

Answer:

h(x) = x³ + 4x² - 49x - 196

Step-by-step explanation:

h(x) = (x² - 49)(x + 4) <== distribute

h(x) = x²(x) - 49(x) + x²(4) - 49(4)

h(x) = x³ - 49x + 4x² - 196 <== rewrite in standard form (descending degrees)

h(x) = x³ + 4x² - 49x - 196

Hope this helps!

Explain and show how to find the square root of 50 to the nearest tenth

tigry1 [53]

Answer:

7.1

Step-by-step explanation:

Squared root of 50 is 7.071067812

To the nearest tenth means just 2 numbers like you have in 10.

Approximate the values from right to left till you have just two values . Remember when approximating , values from 5 to 9 are taken as 1 while values from 0 to 4 are taken as 0 and then added to the next value.

If you do this , you’ll end up

getting to 7.1

What are the coordinates of the vertex for f(x) = x2 + 4x + 10?

boyakko [2]

9514 1404 393

Answer:

(d) (-2, 6)

Step-by-step explanation:

We can rewrite the function using vertex form.

f(x) = (x^2 +4x) +10

f(x) = (x^2 +4x +4) +10 -4 . . . . . . . add and subtract (4/2)^2

f(x) = (x +2)^2 +6

Compare to vertex form:

f(x) = (x -h)^2 +k

we see that (h, k) = (-2, 6) . . . . the vertex

<em>Additional comment</em>

The value added and subtracted is the square of half the x-coefficient. Inside parentheses, that value "completes the square". Outside parentheses, that value ensures the overall function remains unchanged.
