Answer:
0.2 seconds
Step-by-step explanation:
The graph of b(t) = -16t^2 + 5t + 15 is a parabola opening downward. The maximum value of b(t) occurs at the vertex. The t-coordinate of the vertex is t = -5 / (2(-16)) = 5/32 = 0.15625 sec ≈ 0.2 sec.
Answer:
<em>Surface Area for cube: 263 inches^3</em>
Step-by-step explanation:
<em>Formula: 2lw + 2lh + 2wh</em>
<em>2(6 1/2)(3) + 2(6 1/2)(7) + 2(3)(7) =</em>
<em>39 + 182 + 42 =</em>
<em>263 inches</em>

Incomplete question. However, here is a similar question attached.
Solve 3x^2 + 17x - 6 = 0.
Based on the work shown to the left, which of these values are possible solutions of the equation? Check all of the boxes that apply
A X=-6
B X=6
C X=-1/3
D X=1/3
E X=0
Answer:
A and D
Step-by-step explanation:
Note that such question requires using completing the square method of solving equations. By using the values X= -6 and X= 1/3 we arrive at a solution.
Answer:
The answer is below
Step-by-step explanation:
A linear function graph can be represented by:
y = mx + b; where m is the slope and b is the y intercept, x is the independent variable and y is the dependent variable.
a) From the graph we can see the graph passes through the point (0, 100) and (20, 400). Hence we can use the following formula to find the equation:

b) An example of real life linear function is the energy consumed per day in kWh. Let us assume 5 kWh is consumed each day by the person. Since the independent variable is the days, it would be on the x axis, while the dependent variable (energy consumed) would be on the y axis.
