Answer:
x²+8x-65=0
Step-by-step explanation:
The equation to be used is
A=side²
The increased side = X
(4+x)² =81
x² +4x+4x=16=81
x²+8x+16-81=0
x²+8x-65=0
Answer: I believe you mean x and y intercepts? They are (0, -1) and (-1/7, 0)
Step-by-step explanation:
Plug in 0 for x and y (one at a time) for each intercept. eg The x intercept is at y=0 and the y intercept is at x=0.
Answer:

And
and if we use the following function on the Ti84 plus we got:
invNorm(0.02,0,1)
invNorm(1-0.02,0,1)
And the values with the middle 96% of the values are:

Step-by-step explanation:
For this case we want to find the limits with the middle 96% of the area below the normal curve, then the significance level would be:

And

invNorm(0.02,0,1)
invNorm(1-0.02,0,1)
And the values with the middle 96% of the values are:

Powers of ten! is the answer
