What is substitution method?
Find the value of any one of the variables from one equation in terms of the other variable is called the substitution method.
Given that;
The height of the football could be describe by the model,
h = - 16t² + 56t + 2 ..... (i)
Where, h describes the height of the ball in feet.
and t is the time in seconds after the ball was kicked.
Now,
At height 51 feet, the time is calculated as;
Substitute h = 51 in equation (i), we get;
h = - 16t² + 56t + 2
51 = - 16t² + 56t + 2
16t² - 56t - 2 + 51 = 0
16t² - 56t + 49 = 0
Solve for t by using quadratic formula;
t = - (-56) ± √(-56)² - 4 × 16 × 49 / 2 × 16
t = 56 ± √3,136 - 3,136 / 32
t = 56 ± 0 / 32
t = 56 / 32
t = 1.75 seconds
Thus, At time 1.75 seconds the ball is in the 51 feet high.

Suppose a certain die has six sides, numbered from 1 to 6, but that the die is peculiar, in that it has the following properties: On any roll, the probability of rolling either a 1, a 4, or a 5 is 1/2, just as it is with an ordinary fair die. Moreover, the probability of rolling either a 5, a 3, or a 2 is again 1/2. However, the probability of rolling a 5 is 7/16, not 1/6 as one would expect of an ordinary fair die.
what is the probability of rolling a 6, a 3, or a 2 on a 6 sided fair die?
What is the probability of rolling anything but a 6?
A. P( 2∪3∪6 ) = 1/2
B. P( 1∪2∪3∪4∪5 ) = 9/16
The probability of an occurrence e can be written as P (e), and its equation is as follows:
P (e) = Number of favorable outcomes / Total number of outcomes
This can only be used with a straightforward event.
The probability will also be influenced by other factors, whether they are imposed or a result of the event's inherent characteristics.
Using a six-sided die,
A) First, in order to gather as much information as possible from the question, we concentrate on the probabilities provided P(1∪4∪5)=1/2 and P(2∪3∪5)=1/2 and we need to use P(5)=7/16.
It's crucial to remember that while using a dice, receiving two values on the same roll is impossible. Due to this and the likelihood of certain circumstances:
P(1∪4∪5) = P(1) + P(4) + P(5) - P(1∩4)(= 0) - P(4∩5)(= 0) - P(1∩5)(= 0) + P(1∩4∩5)(= 0)
P(1∪4∪5)=P(1) + P(4) + P(5)
1/2 = P(1) + P(4) + 7/16
P(1)+P(4)=1/16
If we do the same with P(2∪3∪5), we get:
P(2) + P(3) = 1/16
Now that we have this new knowledge, we can determine P(6):
P(6) = 1 - P(1∪2∪3∪4∪5)
P(6) = 1 - [P(1) + P(2) + P(3) + P(4) + P(5)] -- (There is no chance that two of these will occur simultaneously.)
P(6) = 1 - (1/16 + 1/16 + 7/16)
P(6) = 1 - 9/16
P(6) = 7/16
And with it, we can find P(2∪3∪6):
P(2∪3∪6) = P(2) + P(3) + P(6)
P(2∪3∪6) = 1/16 + 7/16
P(2∪3∪6) = 8/16 = 1/2
B) Keep in mind that the probability you need to know if you wish to roll anything other than a 6 is P(1∪2∪3∪4∪5)" but we found that in part A
P(1∪2∪3∪4∪5) = 9/16

if the numerator of a fraction is multiplied by 4 and the denominator is reduced by 2, the result is 2. If the numerator of the fraction is increased by 15 and 2 is subtracted from the double of the denominator, the result is 9/7. Find the fraction.
Using the given information, the fraction is 3/8
Determining fractionsFrom the question, we are to determine the fraction
Let the numerator of the fraction be x and the denominator be y
From the given information,
"if the numerator of a fraction is multiplied by 4 and the denominator is reduced by 2, the result is 2"
That is,
4x/(y -2) = 2
and
" If the numerator of the fraction is increased by 15 and 2 is subtracted from the double of the denominator, the result is 9/7"
That is,
(x + 15)/(2y - 2) = 9/7
From the first equation,
4x/(y -2) = 2
4x = 2(y-2)
4x = 2y - 4
4x + 4 = 2y
y = 2x + 2 ----------- (3)
From the second equation,
(x + 15)/(2y - 2) = 9/7
7(x + 15) = 9(2y - 2)
7x + 105 = 18y - 18
Substitute equation (3)
7x + 105 = 18(2x + 2) - 18
7x + 105 = 36x + 36 - 18
105 - 36 + 18 = 36x - 7x
87 = 29x
x = 87/29
x = 3

y = mx + b, where m and b are numbers:
m is the slope of the line and b is the y intercept.
In this case we have the equation:
6 - 2y = - 6
We clear y so we can identify m and b
6 - 2y = -6
6 = -6 + 2y
6 + 6 = 2y

The value of y varies directly with x. If y = 8, when x = 4, what is y when x = 48?
Answer:
96
Step-by-step explanation:
If Y is directly proportional (or in this case varies directly) then whatever you do to one value you do to the other.
So in this case, when Y = 8 and X = 4 that means that Y is double of X (cause 8 is double 4).
So when X = 48 all you need to do is double X which will give you 96.

A hiker walked 15 miles from 8:00 a.m. to noon. He walked an additional 18 miles from 1:00 p.m. to 7:00 p.m.
What is his average rate for the entire walk, in miles per hour?
The average rate for the entire walk of hiker is 3.75 miles per hour by the concept of average speed.
What is average speed?The instantaneous speed is the upper limit of the average speed as the duration of the time interval approaches zero. An object's average speed during a certain period of time is equal to its distance traveled over that period divided by its duration. Speed and velocity are distinct concepts.
The whole distance traveled divided by the total time results in the average rate for the entire walk, expressed in miles per hour.
Given that:
Distance A = 12.8 miles
Distance B = 17.2 miles
Total distance = Distance A + Distance B
Total distance= 12.8 + 17.2
Total distance= 30 miles
Time A = 9:00 a.m. to noon = 3 hours
Time B = 1:00 p.m. to 6:00 p.m. = 5 hours
Total time = Time A + Time B
Total time= 3 + 5
Total time= 8 hours
Average rate = Total distance/Total time
Average rate= 30 miles/8 hours
Average rate= 3.75 miles per hour
Therefore, the average rate for the entire walk of hiker is 3.75 miles per hour.

If 42 burritos were sold, determine all possible values for the number of tacos that Julia must sell in order to meet the requirements. Your answer should be a comma separated list of values. If there are no possible solutions, submit an empty answer.
Julia must sell 21 tacos to meet the requirement .
Given: Price of each taco = $ 3.75
Price of each burrito = $ 6
Total amount of money she needs to earn = $ 330
Also the number of burritos sold= 42.
So the total amount earned on selling these burritos= 42× 6 = $ 252
And as it is given that total money she needs to earn is $ 330 .
so required money= $ 330- $ 252
=$ 78
Thus the total number of tacos she needs to sell = 78/ price of 1 taco

[tex]\begin{gathered} P(A\cap B)=P(A)\times P(\frac{B}{A}) \\ P(A\cap B)=0.6\times0.63 \\ P(A\cap B)=0.378 \end{gathered}[/tex]Wilson viaja 53.7 millas en 1.6 horas. ¿Cuál es su velocidad promedio a la décima de milla por hora
más cercana?
Uniform line movement.
The uniform rectilinear movement is the movement that maintains a variation of the distance with respect to time always constant, since the acceleration is zero.
If we know that Wilson travels 53.7 miles in 1.6 hours, we determine the average speed from the following equation:
Speed = distance / time
Speed = 53.7 miles / 1.6 hours
Speed = 33.5625 miles/hour
V = 33.6 miles/hour
The average speed that Wilson travels is: V = 33.6 miles/hour.
