Anit [1.1K]

Answer:

Step-by-step explanation:

pi / 2 is equal to 180°/2 which is 90°.

Cos (90°) = 0

if cos90 = 0 then what kind of graph will we have at 90° to the x axis ?

a graph passing through the origin. (0,0)

Please find the value?

lesantik [10]

Answer:

Step-by-step explanation:

By the marks on the angles of this triangle, it is isosceles. By the Isosceles Triangle Theorem, if 2 angles of a triangle have the exact same measure, then the sides across from those angles have the exact same measure as well. That means that, algebraically,

5x - 2 = 33 and

5x = 35 so

x = 7

What is the x-intercept of the equation y = 2/3x + 12? Please explain each step for better understanding, thank you:)

VARVARA [1.3K]

Answer:

(-18, 0)

Step-by-step explanation:

The x intercept has a y value of 0. So, to find the x intercept, plug in 0 as y into the equation, and solve for x:

y = 2/3x + 12

0 = 2/3x + 12

-12 = 2/3x

-18 = x

So, the x intercept is (-18, 0)

Find the slope of the line that passes through (-6, -2) and (-7, -2)

Jobisdone [24]

Answer:

$0$

Step-by-step explanation:

We could use the Slope Formula to find the answer, but there's an easier way of doing it. Notice that the y-coordinates of both points are the same. This means that the line that passes through these points is horizontal, which makes our answer $0$ because all horizontal lines have a slope of $0$ .

All horizontal lines have a slope of $0$ because the value of y never changes as the value of x changes, so if we were to input any two points on a horizontal line into the Slope Formula, our numerator would be $0$ (because anything subtracted from itself is $0$ ), leaving us with a result of $0$ regardless of the denominator since $0$ divided by anything is $0$ . Hope this helps!
