Answer:
a. 32
b. 48
Step-by-step explanation:
Forty percent of the 80 birds were robins.
a. How many of the birds were robins?
b. How many of the birds were not robins?
___________________
Forty percent of the 80 birds that were robins = 40%/100%
To find how many of the birds were robins, use part/whole = part/whole
40%/100% = ?/80
This will tell us how many exact robins were there
To solve, multiply 80 by 40 and then divide all by 100
80 x 40 ÷ 100 = 32
so 32 of the birds were robins
now for b since 32 of the birds were robins out of 80 birds, subtract 32 from 80.
80 - 32 = 48
Answer:
sure where is the attachment?
Step-by-step explanation:
A generic point on the graph of the curve has coordinates

The derivative gives us the slope of the tangent line at a given point:

Let k be a generic x-coordinate. The tangent line to the curve at this point will pass through
and have slope 
So, we can write its equation using the point-slope formula: a line with slope m passing through
has equation

In this case,
and
, so the equation becomes

We can rewrite the equation as follows:

We know that this function must give 0 when evaluated at x=0:

This equation has no real solution, so the problem looks impossible.
