Answer:
C(-2) = -9
Step-by-step explanation:
Step 1: Define
C(x) = -3x² - 3x - 3
C(-2) = x = -2
Step 2: Substitute and Evaluate
C(-2) = -3(-2)² - 3(-2) - 3
C(-2) = -3(4) + 6 - 3
C(-2) = -12 + 6 - 3
C(-2) = -6 - 3
C(-2) = -9
Answer:
The kinetic energy of the roller coaster is 1600000 J.
Step-by-step explanation:
Given:
Mass of the roller coaster is 8000 Newton's and speed 20.0 meters/seconds.
Now, we need to find the kinetic energy 
of the roller coaster.
So, Mass of roller coaster (m) = 8000 N.
Velocity of roller coaster (v) = 20.0 m/s.
Now, putting the formula of kinetic energy:
Therefore, the kinetic energy of the roller coaster is 1600000 J.
Answer:
x = 3
Step-by-step explanation:
The two triangles at the left have the same angles and share a side, so they are congruent. Therefore, the vertical side is also 6x−2.
Using the same logic, the two triangles on the right have the same angles and share a side, so they are congruent. Therefore, the vertical side is also 9x−11.
So:
6x − 2 = 9x − 11
9 = 3x
x = 3
2 consecutive integers : x and x + 1
x + x + 1 = 183
2x + 1 = 183
2x = 183 - 1
2x = 182
x = 182/2
x = 91
x + 1 = 91 + 1 = 92
ur 2 numbers are 91 and 92 with 91 being the smallest integer
The reduced 5/2 I simped it by using a fraction simplifer.
