-1. Plug in -3 for x which makes 9-10 so -1
<span>y = –16x2 + 24x + 1
</span>(downward parabola)
it is a height
when the ball is 6ft above the ground
This is a working backwards question.
Since the golf ball was 45g, and the bag was 1.8kg,we need to make them the same units.
45g= 0.45kg
1.8kg= 1.8kg
Now that the units are the same, we put it in a calculator.
1.8÷0.45= 4
Therefore, there are 4 golf balls in the bags.
We can check this by doing 4×0.45= 1.8
Hope this helped!
Answer:
36
Step-by-step explanation:
x^2 + 12 x = 40
To complete the square, take the coefficient of the x term
12
Divide by 2
12/2 = 6
Square it
6^2 = 36
Add 36 to each side
Since you have 8 marbles of a color other than white, and only two white marbles your chance of getting a white marble at random is 2/10.
