Below, I added what the graph of (x^2)-2 looks like...
The answer is A. (0, -2); Minimum
B. For each hour he works, his earnings go up by $8
Answer:
<h2>Frank speed = 37mi/h</h2><h2>Gregory speed = 59mi/hr</h2>
Step-by-step explanation:
Let the speed of Frank be x and speed of Gregory be y. If Gregory drives 22 miles per hour faster than Frank, then y = 22+x. SInce they they are 216miles apart after 2.25 hours,
Speed = Distance/Time
Total time travelled by them = 2.25hours
Total distance = 216 hours
Total speed = x+y = x+22+x
Substituting this parameters into the formula given to get x we will have;
x+22+x = 216/2.25
2x+22 = 96
2x = 96-22
2x = 74
x = 74/2
x = 37
<em>Hence the speed of Frank is 37miles per hour while that of gregory is 37+22 = 59miles/hour</em>
Answer:
The correct solution is "$1618.79".
Step-by-step explanation:
The given values are:
Home price,
= $300,000
Down payment,
= 10%
Mortgage,
= $270,000
Rate,
r = 6%
Time,
t = 30 years
As we know,
⇒ ![PV=P[\frac{1-(1+r)^{-n}}{r} ]](https://tex.z-dn.net/?f=PV%3DP%5B%5Cfrac%7B1-%281%2Br%29%5E%7B-n%7D%7D%7Br%7D%20%5D)
On substituting the values, we get
⇒ ![270 000= P[\frac{1-(1+\frac{6}{1200} )^{-12\times 30}}{\frac{6}{1200} } ]](https://tex.z-dn.net/?f=270%20000%3D%20P%5B%5Cfrac%7B1-%281%2B%5Cfrac%7B6%7D%7B1200%7D%20%29%5E%7B-12%5Ctimes%2030%7D%7D%7B%5Cfrac%7B6%7D%7B1200%7D%20%7D%20%5D)
⇒
