The height, h, in feet of a ball above the ground is given by h= -16t^2+64t+80, where t is the time in seconds. How long does it take the ball to hit the ground?
A) 3 seconds
B) 4 seconds
C) 5 seconds
D) 6 seconds
Answer:
It is 5 seconds option C
Step-by-step explanation:
When the ball would hit the ground, h would reduce 0.
We can equate the R.H.S to 0.
∴ 0= -16t²+64t+80
0 = t² - 4t - 5 (dividing both sides by -16)
0 = t²+t - 5t -5 (by splitting the middle term)
0 = t ( t+1) -5 (t+1)
0= (t-5) * (t + 1)
when t-5=0 ; when t+1=0
t =5 ; t= -1 time cannot be -ve
∴ t= 5 seconds
Hope this helps you.
Answer:
C) 5 seconds
Step-by-step explanation:
Given equation:
[tex]h=-16t^2+64t+80[/tex]
where:
h = height of a ball above the ground (in feet).t = time (in seconds).The ball hits the ground when the height is zero.
Therefore, substitute h = 0 into the given equation and solve for t.
[tex]\begin{aligned}\implies -16t^2+64t+80 & = 0\\-16(t^2-4t-5) & = 0\\t^2-4t-5 & = 0\\t^2-5t+t-5&=0\\t(t-5)+1(t-5)&=0\\(t+1)(t-5)&=0\\\end{aligned}[/tex]
Apply the zero-product property:
[tex]\implies t+1=0 \implies t=-1[/tex]
[tex]\implies t-5=0 \implies t=5[/tex]
As time cannot be negative, t = 5 only.
Therefore, it takes 5 seconds for the ball to hit the ground.

How to solve linear equation
You can use elimination and substitution method
EXAMPLE :
Given :
2x + y = 5
3x - 5y = 1
2x + y = 5 (× -5)
3x - 5y = 1
__________
-10x - 5y = - 25
3x - 5y = 1
____________ _ (elimination)
-13x = - 26
x = - 26/-13
x = 2
Substitution x = 2 to 2x + y = 5 :
2x + y = 5
2(2) + y = 5
4 + y = 5
y = 5 - 4
y = 1

Answer:
like what do you want to remember.
Sadie is doing weekly payroll for her employees at her car dealership. Her employees make a base salary plus commission. The function LaTeX: E(x)=\mid 5- \frac{6x}{2}\mid models the way Sadie calculates the commission where x represents the number of cars the employee sells. If one of her employees sells 7 cars, how much commission will they make?
The commission function is an illustration of the absolute functions
The commission for the sales of 7 cars is 16
The function is given as:
[tex]\mathbf{E(x)=\mid 5- \frac{6x}{2}\mid}[/tex]
When an employee sells 7 cars, we have:
x = 7
So, the equation becomes
[tex]\mathbf{E(x)=\mid 5- \frac{6\times 7}{2}\mid}[/tex]
Simplify
[tex]\mathbf{E(x)=\mid 5- 3\times 7\mid}[/tex]
[tex]\mathbf{E(x)=\mid 5- 21\mid}[/tex]
Simplify
[tex]\mathbf{E(x)=\mid- 16\mid}[/tex]
Remove absolute brackets
[tex]\mathbf{E(x) = 16}[/tex]
Hence, the commission for the sales of 7 cars is 16

2. A baseball game has a total of 9 innings. In each inning, there are 2 teams that each have
to make 3 outs in order for the inning to be complete. Which statement is true?
9
A. Each out is of all the outs in a 9-inning baseball game.
B. Each out is of all the outs in a 9-inning baseball game.
C. Each out is of all the outs in a 9-inning baseball game.
27
D. Each out is
of all the outs in a 9-inning baseball game.
18
Using proportions, it is found that each out is [tex]\frac{1}{54}[/tex] of all the outs in a 9-inning baseball game.
Supposing a 9-inning baseball game, each team has the right to 27 outs.
Two teams, thus, there are [tex]2 \times 27 = 54[/tex] outs.
This means that each out in a game [tex]\frac{1}{54}[/tex] of all the outs in a 9-inning baseball game.

Is 53.7. 104 written in scientific
notation? Why or why not?
Assuming the expression is [tex]53.7 * 10^{4}[/tex].
Answer:
No
Step-by-step explanation:
Scientific notation is where a number is written in the form [tex]a*10^{b}[/tex] where [tex]a[/tex] and [tex]b[/tex] are integers AND [tex]1<=a<10[/tex].
In our expression, [tex]53.7>=10[/tex], so it doesn't satisfy the requirements of scientific notation.
So, the answer is [tex]\boxed{no}[/tex], it's not written in scientific notation.
