-2(2)-6(-2)-5
-4+12-5
Answer is 3
Answer:
9
Step-by-step explanation:
x² − 36 = 5x
x² − 5x − 36 = 0
(x − 9) (x + 4) = 0
x = 9 or -4
If

is the variable of the horizontal axis, then you can solve for

to get the equation of the line in slope-intercept form in the

plane:

i.e. a line with slope

through the origin, which means it is contained in the first and third quadrants. Since the terminal side of

has a negative sine, the angle must lie in the third quadrant.
Because the slope of the line is

, you can choose any length along the line to make up the hypotenuse of a right triangle with reference angle

. Any such right triangle will have

, regardless of whether the angle is the first or third quadrant. But since

is known to lie in the third quadrant, and so

and

are both negative, you have
Answer:
Larissa takes 59.141 seconds to complete both laps.
Step-by-step explanation:
The complete time is the sum of time taken on each lap. We translate the two statements into mathematical expressions to determine the required output:
(i) <em>She completes her first lap in 31.135 seconds</em>:

(ii) <em>She completes her second lap 3.129 seconds faster than the first lap</em>:



Then, the time taken by Larissa to complete both laps is:


Larissa takes 59.141 seconds to complete both laps.
Answer:

Step-by-step explanation:
We first need to know the square root of I then add 10 on that square root since r is 10 more than the square root of I
Therefore,
