If f(x) = -4x + 3 and g(x) = 3x^2 + 2x - 4 find (f+g) (x)

Answer:

3x^2-2x-1

Step-by-step explanation:

Here, we want to find (f + g)(x)

Mathematically, that will be f(x) + g(x)

= -4x + 3 + 3x^2 + 2x -4

= -2x-1 + 3x^2

= 3x^2-2x-1

What is the area of rectangle ABCD with vertices A -3,0 B 3,2 C 4,-1 D -2,-3
Naddik [55]

For this, simply find the width and length by finding the distance between the two points. This can be done using the equation \sqrt{(y2 - y1)^2 + (x2 - x1)^2}

AB(length): \sqrt{(0 - 2)^2 + (3 - (-3))^2}

--> \sqrt{-2^2 + 6^2}

---> \sqrt{40} = 6.32

BC(width): \sqrt{(2 - (-1))^2 + (4 - 3)^2

--> \sqrt{(2 + 1)^2 + 1^2}

---> \sqrt{27 + 1}

----> \sqrt{28} = 5.29 ≈ 5.3

Area = 33.496 ≈ 33.5

After t seconds, a ball tossed in the air from the ground level reaches a height of h feet given by the equation h = 144t-16t^2
lesantik [10]
144t-16t^2= 16t(9-t)
after 3 seconds (just substitute t=3):
16(3)(9-3)=
16(3)(6)=
16*18=
288
maximum height: find the average of the roots:
the roots of 16t(9-t) are t=0 or t=9
since it's a parabola, the maximum is at t=4.5, at 324 ft
if its height is 224 feet, the equation is 224=144t-16t^2
16t^2-144t+224=0
divide by 16: t^2-9t+14=0
this can be factored as (t-2)(t-7)=0
the roots are t=2 and t=7, so the ball has been in the air for either 2 seconds or 7 seconds
the roots to 144t-16t^2 are 0 and 9, so the ball will hit the ground 9 seconds after being thrown
