Answer:
its 20
Step-by-step explanation:
you add 8 + 12 which is 20 then you divide it by 4 which is 5 then you multiply 4 which is 20
Ax² + bx + c = 0
2x² + x - 3 = 0
2x² + x + (-3) = 0
x = <u>-b +/- √b² - 4ac</u>
2a
x = <u>1 + /- √1² - 4(2)(-3)</u>
2(2)
x = <u>1 + /- √1 +24</u>
4
x = <u>1 +/- √25
</u> 4<u>
</u>x = <u>1 + /- 5
</u> 4<u>
</u>x = <u>1 + 5</u> x = <u>1 - 5
</u> 4 <u> </u> 4<u>
</u>x = <u>6</u> x = <u>-4</u>
4 4
x = <u>3</u> x = -1
2
x = 1 1/2
x = 1 1/2 x = -1

<h3>See solution below</h3>
Step-by-step explanation:
Find the complete question below;
Given the height modeled by the function;
h(t) = 5 + 98t-4.9t²
when t = 0
h(0) = 5 + 98(0)-4.9(0)²
h(0) = 5
when t = 5
h(5) = 5 + 98(5)-4.9(5)²
h(5) = 5 + 490 - 122.5
h(5) = 372.5
when t = 10
h(10) = 5 + 98(10)-4.9(10)²
h(10) = 5 + 980 - 490
h(10) = 495
when t = 15
h(15) = 5 + 98(15)-4.9(15)²
h(15) = 5 + 1470 - 1,102.5
h(15) = 372.5
when t = 20
h(10) = 5 + 98(20)-4.9(20)²
h(10) = 5 + 1960 - 4.9(400)
h(10) = 1965- 1960
h(10) = 5

Answer:
I think i don't really know its been awhile for me.
Step-by-step explanation:
But i think you do 2 x 10 and what ever you get from that you multiply by 5 and what get from that you divide by 24.
I may not be right.
So please don't hate i tried.
