<span>Distance is equal to rate times time, and time is the unknown in this instance. To find time, divide distance by rate. In this case, Joe wants to use a rate five miles per hour less than his planned speed of 75 miles per hour, which is 70. Dividing 310 miles by 70 miles per hour yields an expected travel time of 4.4 hours.</span>
In general, you just need to follow the formula for amplitude:v
y = A*sin(Bx - C) + D
The amplitude is |A|
For our problem <span>y = 5 sin 1/2x the amplitude and the answer to your question is 5.</span>
Answer:
44
Step-by-step explanation:
Hello There!
To solve this one all we have to do is plug in 5 for a
so
9(5)-7+6
9x4=45
45-7=38
38+6=44
so when a=5 the value of the expression is 44
The answer is D, no solution
