Answer:
g(x) = x² -3
Step-by-step explanation:
There is no vertical scaling (a=1) or horizontal shift (h=0). The only shift is a down shift by 3 units (k=-3), so the transformed equation is ...
g(x) = x² -3
Answer:
t = 5 seconds
Step-by-step explanation:
We have,
Speed of the truck, v = 4 m/s
It is required to find the time taken by a truck to travel 20 meters. It can be assumed that the time is t. Using the formula of speed.
After rearranging, we get :
So, the time taken by a truck to travel 20 meters is 5 seconds.
Discriminant = sq root of b^2 - 4*a*c =
sq root of 36 - 4*1*13 =
sq root 36 -52 =
sq root 36 -52 =
sq root -16
There are no real solutions for this equation. Both roots are complex numbers.

Answer:
Step-by-step explanation:
The formula for determining the length of a rectangle is expressed as
Area = length × width
The large rectangle has a length of 10 units and width 5 units. The area of the large rectangle would be
10 × 5 = 50 units²
Inside this rectangle is a smaller rectangle of length 4 units and width 2 units. The area of the smaller rectangle would be
4 × 2 = 8 units²
Probability is expressed as favorable outcome/total number of possible outcomes
The region that is not shaded grey is
50 - 8 = 42 units²
The probability that a point chosen inside the large rectangle is not in the shaded region is
42/50 = 0.84
Converting to percentage, it becomes
0.84 × 100 = 84%
