Answer: $43.28
Step-by-step explanation: To find the sales tax, first convert 8.25% to a decimal. 8.25% as a decimal is 0.0825.
Now simply multiply 0.0825 x 39.98 which equals about 3.30
So, the total sales tax is $3.30
Now add $3.30 to $39.98 which equals a total cost of $43.28
5 < t < 15
t > 15
The particle always moves to the right.
Answer:
Option D is correct.
as the particle always moves to the right
Step-by-step explanation:
Given the function: , 0<t<15;
where
s(t) represent the distance in feet.
t represents the time in second.
Since, when the particle is moving to the right,
⇒ s(t) is increasing.
so,
Find the derivative of s(t) with respect to t;
Use derivative formula:
Simplify:
As
⇒
[ ]
⇒ this is always true because square of any number is always positive
Therefore, it means that the particle always moves to the right.
y = x – 5
Which description best describes the solution to the system of equations? (4 points)
Lines y = –2x + 3 and y = 3x - 5 intersect the x-axis.
Line y = –2x + 3 intersects line y = x – 5.
Lines y = –2x + 3 and y = 3x – 5 intersect the y-axis.
Line y = –2x + 3 intersects the origin.
The answer above/below is incorrect!!!!!!!!!!!!!! I just took the test and it was wrong!!!!
