Answer:
The area increases by 6 square units.
Step-by-step explanation:
The original area of triangle
A = 1/2 bh
a = 1/2 (4)*3
6 square units
Now we double the height
A = 1/2 (4) *6
A = 12 square units
The difference is 12-6 = 6 square units
81+9=90 that is the answer. Hope it helped
Answer:
[-4,5]
Step-by-step explanation:
you look on the starting point and the ending point of the y-axis ( you always start with the smallest value)
Answer:
2
Step-by-step explanation:
Given the average rate of change formula, we must first find the x and y values of the function.
We are provided with the two x values, 1 and 2. We now need to find the output, or y.
ƒ(x)=3^x-4x
ƒ(1)=3-4=-1
ƒ(2)=9-8=1
Then, we use the formula (ƒ(2)-ƒ(1))/x2-x1(subscripts here, in case you multiplied) which gets us 2/1, or 2. Therefore, the average rate of change(ARC) is 2. I believe you just need to find the output and subtract if they are exactly one whole number apart, but don't quote me on that.
