Answer:
8 laps in 70 seconds is faster.
Step-by-step explanation:
If we divide 70/8 and 98/12 we get the following:
70/8= 8.75
98/12=8.16
8.75>8.16
The unit rate is 1 lap in 8.75 seconds and 1 lap in 8.16 seconds
Answer:
C = 0.65x + 145
Step-by-step explanation:
Assume:
Number of miles = x
Annual maintenance = $145
Total reimbursement = C = $0.65*x + $145 = $0.65x + $145
Answer:
1
Step-by-step explanation:
Since tan(x) = sin(x)/cos(x), if sin(x) = cos(x) then tan(x) must be 1.
You can even reason that the acute angle is 45° and sin(x)=cos(x) =
.

Answer:

Step-by-step explanation:
A quadratic function is a function in which the highest power of the unknown variable is 2.
Formally, a quadratic function is defined as a function of the form:

From the given options, only B and D has the highest power as 2. Therefore, the equations that represent quadratic functions are:
