Answer:
The height of the stone at the time it is thrown is 15.
Step-by-step explanation:
You have a quadratic function of the form h (x) = ax² + bx + c. In this case it is h (x) = -5x²+10x+15, where a =-5, b =10, c =15, x is the time and h (x) is the height of the stone after being thrown.
The moment the stone is thrown is instant zero. So if x = 0, h (0) is calculated:
h(0)= -5*0² +10*0 +15
h(0)= 0 + 0 + 15
h(0)= 15
The height of the stone at the time it is thrown is 15.
Answer:
2.25
Explanation:
1 1/2 * 1 1/2 * 1 = 2.25 or 2 1/4
U just add one more zero to the as many 1 hundred
The scale before you simplify would be 4 inches=380 miles
You then convert it into a fraction 4/380 and simplify
4/380=1/95
It would not be A, B, C, or D, the person who had created the test has made a mistake
First see what the slope of the line. If you see a line that is going up, x is positive. If you see a line that is going down, x is negative. Now, look at the “y” line, find where x is zero, positive 3 or negative 3, that would be your y-intercept.
