Answer: 10
Step-by-step explanation:(-x)(5y)(-2x)
=(-5xy)(-2x)
=10x^2y
therefore,the coefficient of the equation is 10.
Scale shows weight = 193
Weight of assistant = 135
Weight of dog = x
x = 193 - 135
x = 58
The dog weighs 58 pounds.
Answer:V(x) = 6x³ + 4x² - 12x - 8
Step-by-step explanation:
The shoe box can either be cube shaped or cubiod shaped. The volume of the box is length × breadth × height
Since Area = Length × Breadth
Volume = Area × Height
V(x) = A(x) × H(x)
A(x) = 2x² - 4
H(x) = 3x + 2
V(x) = (2x² - 4)(3x + 2)
V(x) = 6x³ + 4x² - 12x - 8
Answer:
A. Rectangle
Step-by-step explanation:
It is often useful to plot the given points on a graph. Doing that lets you see the figure is a rectangle. You can count grid squares to see that the distances are the same between the endpoints of opposite sides.
For this case we have the following equation:
h = -16t ^ (2) + 30t + 6
We substitute the value of h = 10 in the equation:
10 = -16t ^ (2) + 30t + 6
Rewriting we have:
0 = -16t ^ (2) + 30t + 6-10
0 = - 16t ^ (2) + 30t - 4
We look for the roots of the polynomial:
t1 = 0.144463904
t2 = 1.730536096
"the ball passes its maximum height, it comes down and then goes into the hoop". Therefore, the correct root is:
t = 1.730536096
Answer:
It goes into the hoop after:
t = 1.73 seconds
