If anyone can help with either one that’d be great

Volgvan

4. Solve

$1430 = 0.55t^2 + 550$

$1430 - 550 =880 = 0.55t^2$

$880/0.55 = 1600 = t^2$

$t= \pm \sqrt{1600} = \pm 40$

On the positive answer makes sense.

Answer: Month 40

5. The throw ends when the height is zero (I guess we're ignoring rolling).

$0 = -0.02x^2 + x + 6$

$x = \dfrac{-1 \pm \sqrt{1^2 - 4(6)(-0.02)}}{2(-0.02)}$

Only the negative sign for the plus/minus will give a sensible, positive answer:

$x = \dfrac{-1 - \sqrt{1^2 - 4(6)(-0.02)}}{2(-0.02)} = 55.4138$

Answer: 55.4 feet

The product of two consecutive even integers is 840 find these numbers

musickatia [10]

Integers are 2n and 2n +2
2n * (2n + 2) = 840
4n^2 + 4n -840 = 0
Solving by quadratic formula:
n = 14 and n+2 = 16
Therefore the integers (2*n and 2*n+2) are
28 and 30

check:
28 * 30 = 840
