The angle measure of a straight line is 180°, and so if the you know that one angle off of it is (5x)°, then you know that the other section is (180 - 5x)°.
Because it's an isosceles triangle, there are two identical angles, which happen to be the angles with the measure of (5x - 30)° and (180 - 5x)°.
Since they have the same measure, 5x - 30 = 180 - 5x. Solve:
Thus,
x = 21°.
Answer:
1020
Step-by-step explanation:
well, the first three significant figures stops at the 102, so round the 1023.4567 to a whole number which just becomes 1023
then, round the answer so you only have the 102, so you would round down since 4 or less, which 3 is less than 4, you round down, and you would get 1020
that last 0 is not a significant figure because it does not have a decimal point or any other number following after it--any 0s at the end of a number are not significant if there is no decimal point or other number after them.
Answer: (x+3) (x-20)
Step-by-step explanation:
Answer:
There are 3 critical values of f on the open interval (0,10).
Step-by-step explanation:
It is given that the first derivative of the function f is
We need to find the number of critical values of f on the open interval (0,10).
To find the critical values we have to find the value of x for which f'(x)=0.
Using graphing calculator we get
All the values 1.086, 2.320, 3.681 lie on the interval (0,10).
Therefore, there are 3 critical values of f on the open interval (0,10).
Answer:
the first option
Step-by-step explanation:
i know there's a rule to all of this but it's been a while since i've done this kind of math.
if you plug in the zeros to the equation, they solve
(-2, 0) --> (-2-2)(-2+1)(-2+2) = 0
(-1, 0) --> (-1-2)(-1+1)(-1+2) = 0
(2, 0) --> (2-2)(2+1)(2+2) = 0
