You find this value by factoring. Factoring finds the zeros of the function. When the ball hits the ground, it has 0 height. Therefore, when the function goes through the x axis, it has a y value of 0. That means that when y = 0, the ball has hit the ground. Use the quadratic formula to factor
. Notice I rearranged the terms. When you factor that you get zeros of -3.19 and 2.19. The two things in math that will never EVER be negative are time and distance/length. Therefore, that tells us that the ball hits the ground 2.19 seconds after it was thrown.
Significant figures are the digits that carry meaning to its measurement. Significant figures includes all the numbers excluding all the leading zeros, trailing zeros. All non zero digits are significant. Zeros between the non zero digits are significant. In a decimal number, trailing zeros are significant.
Now, consider the given number 0.23350
Since, in a decimal number all the trailing zeros are significant.
So, in the number 0.23350 there are five significant figures 2,3,4,5 and 0.
Therefore, there are 5 significant figures in the given number.
Answer:
D) 65 I believe
Step-by-step explanation:
What I did what 20 divided by 4, which gave me 5 doses per ounce. Then I multiplied 5 times 13 and that gave me 65
Answer:
x^3 -10x + 57
Step-by-step explanation:
$16,000 at 9% interest
9% of 16,000 is 1440
If she paid the loan off in 5 years she would have to pay $23,200
If she paid the loan off in 3 years she would have to pay $20,320
She would save $2880 in interest.
