90 in terms of pi is \frac{\pi}{2} .

<u>Step-by-step explanation:</u>

We know that ,

  • Degrees are a unit of angle measure. A full circle is divided into 360 degrees. For example, a right angle is 90 degrees. A degree has the symbol ° and so ninety degrees would written 90°. Another unit of angle measure is the radian.
  • The radian is the SI unit for measuring angles, and is the standard unit of angular measure used in many areas of mathematics. The length of an arc of a unit circle is numerically equal to the measurement in radians of the angle that it subtends; one radian is just under 57.3 degrees.

We have to convert 90 in terms of pi i.e. degree to radians:

⇒ (90)\frac{\pi }{180}

⇒ \frac{90 }{180}(\pi)

⇒ \frac{1 }{2}(\pi)

⇒ \frac{\pi}{2}

Therefore, 90 in terms of pi is \frac{\pi}{2} .

Find the vertex of this function <br> f(x)= x^2+4x-12
sergij07 [2.7K]
F(x) = x² + 4x - 12

x = -b/2a
x = -(4)/2(1)
x = -4/2
x = 2

f(x) = x² + 4x - 12
f(2) = (2)² + 4(2) - 12
f(2) = 4 + 8 - 12
f(2) = 12 - 12
f(2) = 0

The vertex of the function is (2,0).

If two sides of a triangle measure 12 and 7, which cannot be the perimeter of the triangle?
ser-zykov [4K]
Hi,
Let assume x the 3th side.
x<12+7==> x<19
12<x+7==>x>5
So 5<x<19==> 5+7+12<x+7+12<19+7+12
==>24<x<38
