f(x) = −5x2 − x + 20, find f(3).

Substitute x = 3 into the function

f(3) = −5(3)^2 − 3 + 20

f(3) = -45 - 3 + 20

f(3) = -28

Answer

−28

Fill in the other coordinate for the line y=7/2x +6 (-3
erik [133]
We have the following equation:
 y = 7 / 2x +6
 For this case, what we must do is replace the value of x = -3 in the given equation.
 We have then:
 y = (7/2) * (- 3) +6
 y = -4.5
 Therefore, the other coordinate is:
 (-3, -4.5)
 Answer:
 
(-3, -4.5)

6) BRAINLIEST &amp; 10 + POINTS!
MA_775_DIABLO [31]

Answer:

the height of the building is approximately 134 yards

Step-by-step explanation:

Recall that i order to use the arc-length formula:

arc\,\,length=R\,\theta

we know the radius R, but the angle \theta must be given in radians. Then we convert 4.5^o to radians, and then use 1700 yards as the radius in the formula.

4.5^o*\frac{\pi}{180} =0.07854

Therefore, the arc length formula would render:

arc\,\,length=R\,\theta\\arc\,\,length=1700\,(0.07854)=133.518\, yards

which rounded to the nearest yard becomes: 134 yards
