Answer:
a) The maximum height that the ball reaches is 73.1 meter
b ) The time elapsed when the ball reaches its maximum height of flight = 2.2 seconds
Step-by-step explanation:
The complete question is
During a high school baseball tournament, Lando hits a pitch and the baseball stays in the air for 4.42 seconds. The function h(t) = -5t2 + 22t + 0.5 describes the height over time, where h is its height, in meters, and t is the time, in seconds, from the instant the ball is hit. a. What is the maximum height the ball reaches? b. What will be the time elapsed when the ball reaches its maximum height of flight?
Solution:
For maximum height
[tex]\frac{dh}{dt} =0[/tex]
[tex]\frac{d(5t^2 + 22t + 0.5)}{dt}\\ 10t + 22 = 0\\t = 2.2[/tex]seconds
a) Maximum height
[tex]5 * t^2 + 22t + 0.5[/tex]
[tex]= 5 * 2.2 *2.2 + 22 * 2.2 + 0.5 \\= 73.1[/tex]
b) Time elapsed when the ball reaches maximum height is 2.2 seconds

What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
If Hunter practices five days a week and a minimum of 450 minutes per week, then the total practice time for the week is at least 5 * 450 = 2250 minutes.
To find the average practice time per day, we can divide the total practice time for the week by the number of days:
The average practice time per day = total practice time for the week / number of days
The average practice time per day = 2250 / 5 = 450 minutes
Hence , on average, each basketball practice is 450 minutes/5 = 90 minutes

What is the distance between (2, 5) and (2,-5) on the coordinate plane
Answer:
10
Step-by-step explanation:
When you find the distance, you just add both of the numbers as if they were in absolute value 5+|-5|
so then since the x values are the same, you would go up/down 10 spaces on the Y-axis
Answer:
10 units
Step-by-step explanation:
Use the distance formula:
[tex]\sqrt{ (x_{2} - x_{1} )^2 -(y_{2} - y_{1} )^2[/tex]
Plug in values:
[tex]\sqrt{ (-5-5 )^2 -(2-2 )^2[/tex]
[tex]\sqrt 100[/tex]

Some number subtracted by -6 is 41. Multiply this number by-3. Then divide
this number by -4. What is the final number?
Answer:
The final number is 26.25.
Step-by-step explanation:
First, solve the beginning sentence.
"Some number" can be represented by x
x - (-6) = 41
x + 6 = 41
x = 35
Next, solve the second sentence
35*(-3) = -105
Finally, the last sentence
(-105)/(-4) = 26.25

A bag contains 21 coins consisting of nickles and dimes. The total value of the coins is $1.70.
Write a system of equations that models this situation. How many nickels are in the bag?
Answer:
8
Step-by-step explanation:
x = nickles
y = dimes
0.05x + 0.10y = 1.70
x + y = 21
y = 21 - x
0.05x + 0.10 (21 - x) = 1.70
0.05x - 0.10x + 2.10 = 1.70
-0.05x + 2.10 = 1.70
-0.05x = -0.40
x = 8

Answer:

Step-by-step explanation:
Slope formula is Δy/Δx or (change in y)/ (change in x).
Apply that formula:
You know that 1-(-1) = 2, therefore for a slope of 1/5, the only possibile denominator is 10: 2/10 simplifies to 1/5.
So. What subtracted by 6 is equal to 10? 16.
