The gradient of the function is 5.
y = 5x - 2
vertex form of the equation for a parabola
y = a(x-h)^2 +k
y = a(x--3)^2 +2
y=a(x+3)^2 +2
Choice B
Answer:
The truck is hauling 3/4 of a full load
Step-by-step explanation:
we know that
2/3 ton of gravel represent the 100% of a full load
Find out how much of a full load the truck is hauling with 1/2 ton of gravel, using proportion
Let
x ----> the percentage of a full load

Convert to fraction number

therefore
The truck is hauling 3/4 of a full load

Answer:
A. d = ∑[k=1,n] (4.5+0.5k)
B. 9
Step-by-step explanation:
A) The series has first term 5 and common difference 0.5. The general term is given by ...
an = a1 +d(n -1)
an = 5 + 0.5(n -1) . . . . substitute numbers for this series
an = 4.5 +0.5n . . . . . . simplify
The sum is the sum of these terms:

__
B) The sum of terms of an arithmetic series is the average of the first and last, multiplied by the number of terms. We want to solve for n to make the sum greater than 60.
