Answer:
b =21
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
20^2 + b^2 = 29^1
400 + b^2 =841
Subtract 400 from each side
b^2 = 441
Take the square root of each side
sqrt(b^2) = sqrt(441)
b =21
Answer:
No, some of the ordered pair in this graph have the same first element.
Step-by-step explanation:
The relation of a function is that it expresses a dependence of one element on another. There is a one to one relation, which means that one point can not be used more then once.
Some ordered pairs in this graph have the same first element and are used more then once. So this graph can not represent a function.
The answer to this question will be A
18x^2 - 32 =
2(9x^2 - 16) =
