Step-by-step explanation:
The third option is correct
4(-2)⁻²(4)⁻³
![\frac{4}{(2)^{2}(4)^{3}}}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B%282%29%5E%7B2%7D%284%29%5E%7B3%7D%7D%7D)
Step-by-step explanation:
![\frac{1}{2} (10)(12) \\ \frac{1}{2} (120) \\ 60 {cm}^{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%20%2810%29%2812%29%20%5C%5C%20%20%5Cfrac%7B1%7D%7B2%7D%20%28120%29%20%5C%5C%2060%20%7Bcm%7D%5E%7B2%7D%20)
When the penny hits the ground, h will = 0.
So: Set h(t) = 0 = -4.9t^2 + 0t + 150 m
Then 4.9t^2 = 150, and so t^2 = sqrt(150 / 4.9) = plus or minus 5.53 sec.
We can use only the positive root, as we're measuring time.
t = 5.5 sec (answer)
Answer:
two quadratic functions combined by addition
a linear function and a quadratic function combined by addition
two linear functions combined by multiplication
Step-by-step explanation:
-3x² + 5
(-4x² + 4) + (x² + 1)
-3x² + 5
(-3x² - x) + (x + 5)
-3x² + 5
(sqrt(5) - sqrt(3)x)(sqrt(5) + sqrt(3)x)
