H(w)=-5x^2+80 to factored form
1 answer:
Answer:
- 5(x - 4)(x + 4)
Step-by-step explanation:
Given
- 5x² + 80 ← factor out - 5 from each term
= - 5(x² - 16) ← x² - 16 is a difference of squares and factors in general as
a² - b² = (a - b)(a + b), thus
x² - 16 = x² - 4² = (x - 4)(x + 4)
Thus
- 5x² + 80 = - 5(x - 4)(x + 4) ← in factored form

If she runs 7 miles every hour and runs a total of 11.2 miles, we can set this up as:
Where x represents the # of hours she ran for. Let's solve for x:
So, she ran for a total of 1.6 hours.
100 * ( 12 - 0.02) ^10 =
= 100 * 0.98^10 =
= 100 * 0.8170728 =
= 81.70728 ≈ 81.7 ( to the nearest tenth )
