Y-y1=m(x-X1) is the formula.
m is the slope and the y1 and x1 are your points.
leave x and y; the ones without the 1 and solve for y
Answer:
Acute
Step-by-step explanation:
The Converse of the Pythagorean Theorem states that:
- If then the triangle is acute.
- If then the triangle is obtuse.
- If then the triangle is right.
The side lengths 8, 14, and 15 are given. We can assume the hypotenuse (or c) is the longest side length, so it is 15.
It doesn't matter which order of the numbers are plugged in for a and b, so a and b will be 8 and 14.
Now we have to add and to see if the sum is greater than, less than, or equal to 15 (c).
Calculate the rest of the problem.
We have to find what is before we can make a decision using the Converse of the Pythagorean Theorem.
260 () is greater than 225 (). This means that the triangle is acute because .
You can compose functions c(x) and s(x) in two ways:
1. c(s(x))=0.9x-5
and
2. s(c(x))=0.9(x-5).
The main difference between these two function is the sequence of actions performed. In first case 10% off is applied before the coupon and in second case 10% off is applied after the coupon.
Answer: c(s(x))=0.9x-5
