Formula for area of parallelogram:
A= bh
Where b is the length of base and h is the height.
Here b=2.3+4.5 = 6.8 cm
and h= 4.5 cm
Put values in formula.
A= 6.8 x 4.5
A=30.6 cm²
Answer: 30.6 cm²
Step-by-step explanation:
Given that,
The function that shows the height of a baseball after t seconds is given by :
....(1)
Part (A).
When the baseball hits the ground,
H(t) = 0
So,
![-16t^2+75t+25=0\\\\t=5\ s\ and\ t=-0.31\ s](https://tex.z-dn.net/?f=-16t%5E2%2B75t%2B25%3D0%5C%5C%5C%5Ct%3D5%5C%20s%5C%20and%5C%20t%3D-0.31%5C%20s)
After 5 seconds the baseball will hit the ground.
Pat (B)
For maximum height, put dH/dt = 0
So,
![\dfrac{d}{dt}(-16t^2+75t+25)=0\\\\-32t+75=0\\\\t=2.34\ s](https://tex.z-dn.net/?f=%5Cdfrac%7Bd%7D%7Bdt%7D%28-16t%5E2%2B75t%2B25%29%3D0%5C%5C%5C%5C-32t%2B75%3D0%5C%5C%5C%5Ct%3D2.34%5C%20s)
Put t = 2.34 s in equation (1).
![H(t)=-16(2.34)^2+75(2.34)+25\\\\H(t)=112.89\ m](https://tex.z-dn.net/?f=H%28t%29%3D-16%282.34%29%5E2%2B75%282.34%29%2B25%5C%5C%5C%5CH%28t%29%3D112.89%5C%20m)
Hence, this is the required solution.
Answer:
-5/7
Step-by-step explanation:
When you divide fractions, you flip the second fraction, then multiply.
So it becomes -25/28 x 4/5.
This equals -100/140 which reduces to -5/7.
Answer:
y
Step-by-step explanation:
y needs to provide a number
I believe the term is a "radical"
Hope this helps!
