Answer:
5 ft
Step-by-step explanation:
The area of a trapezoid is given by the formula ...
A = 1/2(b1 +b2)h
The height is found by solving this equation for h:
2A/(b1 +b2) = h
h = 2(25.5)/(3.2 +7) = 51/10.2 = 5 . . . . fill in the given values
The height of the trapezoid is 5 feet.
Answer:
b. 4x^2 + 3x - 6
Step-by-step explanation:
The values of f(x) for the extremes of x are more positive than the value of f(x) for the middle x, so we know the parabola opens upward. That eliminates choice D.
It is probably easiest to evaluate the other expressions to see which one matches the given f(x) values. For the purpose, it is usually easier to use the Horner form of the equation.
a. f(-2) = (3(-2) +4)(-2) -6 = -2(-2) -6 = -2 ≠ 4
b. f(-2) = (4(-2) +3)(-2) -6 = -5(-2) -6 = 4 . . . . matches the given data point
c. Because (b) matches, we know this one will not.
The appropriate choice is B.
I wish i remembered that but it has been a while
Answer:
Step-by-step explanation:
you find the L.C.M
18 234 270 324
13 13 15 18
3 1 15 18
5 1 5 6
6 1 1
1 1 1 ans=18×13×3×5×6=21060
For this , you use the distance formula
. based on the graph, use points (0,6) and (7,-2), plug them into the formula to get

and you get B, 10.63
