Answer:
-3
Step-by-step explanation
If s(t) is equal to -9 - 3t, its derivative is equal to -3 for all values of t. The instantaneous velocity is simply the derivative at that point, so it is -3.
Answer:
a) a + c = 90
d) a + b + c + 30 = 180
e) The angles marked a and b are vertical
f) The angles marked a and c are complementary.
Step-by-step explanation:
A complementary angle is and angle that has a sum of 90 degrees. A vertical angle is 2 angles facing each other, that are completely identical. 180 degrees is the sum of a strait line. 90 degrees is a right angle.
Hope this helps! Have a wonderful rest of your day!

Answer:
14 cm.
Step-by-step explanation:
The formula for the perimeter of a rectangle is P = 2l + 2w, where P is the perimeter, l is the length, and w is the width.
In this case, the width is 4 cm and the length is 3 cm.
P = 2(3) + 2(4)
P = 6 + 8
P = 14
So, the perimeter of the rectangle is 14 centimeters.
