Answer:
The correct answer is 5.
Step-by-step explanation:
When c = 7, then we put that value in for c in the equation c - 2
c - 2
(7) - 2
5
Answer:
±1, ±2, and ±4
Step-by-step explanation:
4x² + bx + c = (Ax + B) (Cx + D)
Distribute:
4x² + bx + c = ACx² + (AD + BC) x + BD
Matching the coefficients, AC = 4. So A must be a factor of 4. Possible values of A are therefore ±1, ±2, and ±4.
Answer:
The rate of descent is 4 ft/min.
He will descent 24 ft in 6 min.
Step-by-step explanation:
Consider the provided information.
He starts at sea level and then descends 10 feet in 2 1/2 minutes.
First convert the mixed fraction as shown:
![2\frac{1}{2}=\frac{5}{2} =2.5](https://tex.z-dn.net/?f=2%5Cfrac%7B1%7D%7B2%7D%3D%5Cfrac%7B5%7D%7B2%7D%20%3D2.5)
Therefore the rate of descent is:
The rate of descent = ![\frac{10}{2.5}=4](https://tex.z-dn.net/?f=%5Cfrac%7B10%7D%7B2.5%7D%3D4)
Hence, the rate of descent is 4 ft/min
Now find In 6 minutes, how much he will descent:
![4\times 6=24](https://tex.z-dn.net/?f=4%5Ctimes%206%3D24)
Hence, he will descent 24 ft in 6 min.
