The correct value of the h function is; h= -9.8t² + 45t + 1
Answer:
Using the discriminant, no real solution exists and the baseball will not hit the roof.
Step-by-step explanation:
We are told the height is expressed as;h= -9.8t² + 45t + 1
Also that the Astrodome has a maximum height of 63.4 m
Thus, to find out if the baseball hit at a velocity of 45 m/s will hit the roof, we'll replace h with 63.4m.
Thus;
63.4 = -9.8t² + 45t + 1
Subtract 63.4 from both sides to give;
-9.8t² + 45t + 1 - 63.4 = 0
-9.8t² + 45t - 62.4 = 0
Using quadratic formula, we have;
t = -45 ± √{(45² - (4 * (-9.8) * (-62.4)}
t = -45 ± √(2025 - 2446.08)
t = -45 ± √(-421.08)
The discriminant is -421.08
This value is less than 0.
Thus, no real solution exists and the baseball will not hit the roof.
Start by drawing a line AB, then half way the line, label C, which is the midpoint. Continue to follow the instruction until all labels are in place.
We know that line DC = 16, that means line AD also 16
Line AE = ED = 8
Line EF = FD = 4
Line FG = GD = 2
Line DB = 16+32 = 48
Line DH = 48/2 = 24
Line GH = 2+24 = 26
Answer:
Step-by-step explanation:
A quantitative variable is the one which is represented numerically and not with words.
Hence option (C) is the quantitative variable as servings per box are represented by numbers. (eg. if in a box of 16 cookies, 1 serving = 1 cookie, then the servings per box will be 16)
Duplicating Polynomials. To duplicate two polynomials, you apply the distributive property . Think about a straightforward model: duplicating a monomial 3x by the binomial x−2 . When you increase one binomial by another binomial, you need to utilize the distributive property over and again.
Hi there!
Take the root (and minus root).
