The player hits the ball up in the air with an upward velocity of 18 ft/sec. The equation that gives the height of the ball at any time ’t’ is h(t) = -8t^2 + 18t + 5. How long did it take for the ball to hit the ground?
^2 being squared for those who dont know.
Solving the quadratic equation, it is found that it took 2.5 seconds for the ball to hit the ground.
What is the quadratic equation for the ball's height?It is given by:
h(t) = -8t² + 18t + 5.
It hits the ground when h(t) = 0, hence:
-8t² + 18t + 5 = 0.
Which has coefficients a = -8, b = 18, c = 5, then:
[tex]\Delta = 18^2 - 4(-8)(5) = 484[/tex]
[tex]x_1 = \frac{-18 + \sqrt{484}}{2(-8)} = -0.25[/tex]
[tex]x_2 = \frac{-18 - \sqrt{484}}{2(-8)} = 2.5[/tex]
It took 2.5 seconds for the ball to hit the ground.

Enrique makes $9.25 per hour and worked 30 hours last week. He also makes 10% commission on the $300 of sales he made last week. How much did he make in total for last week?
Answer:
Final answer=$307.50
Step-by-step explanation:
Given:
Money Enrique makes per hour = $9.25
Total time he worked last week = 30 hours
Commission he got for $300 of sales = 10%
So, total amount of money he made in the last week is,
(Wage he gets per hour)×(No. of hours he worked)
=$9.25×30
=$277.50
Now, we have to find the money he made from the sales with commission of 10%,
= (Money made from sales)×(Commission %)
=$300×10%
=300×10/100
=3×10/1
=$30
Now we calculate the total money he made,
(Money made by working)+(Money from commission)
=$277.50+$30
=$307.50
∴Enrique made $307.50 in total from the last week.
Enrique made $307.50 in total from the last week.
What is a percentage?A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.
Enrique makes per hour = $9.25
He worked 30 hours in a week.
Commission he got for $300 of sales = 10%
Total money
=(Wage he gets per hour)×(No. of hours he worked) + money made from the commission
=$9.25×30 + (Money made from sales)×(Commission in percentage)
=$277.50 + $300×10%
= 277.50 + 300×10/100
=$307.50
Therefore, Enrique made $307.50 in total from the last week.

Gretta played a game in which she could either lose or gain points each round. In the first round, she lost 10 points . In the second round she gained 14 points. Model the changes as a sum of integers
Answer:
Step-by-step explanation:
The points loosed in the first round l = 10 points
Points gained in the second round g = 14points
Let the points loosed be negative while that gained be positive, hence;
l = -10 points
g = +14 points
Change in the integers = l+g
Change in the integers = =-10 + 14
Change in the integers = 4points

The trail starts at P(−7, 6) and goes to Q(4, 6). It goes from Q to R(4, −6) and then to S(6, −6). What is the total length (in units) of the biking trail?
We know, distance between two points A( p,q) and B(r,s) is given by :
[tex]AB=\sqrt{(p-r)^2+(q-s)^2}[/tex]
So, distance between P an Q is :
[tex]PQ=\sqrt{(-7-4)^2+(6-6)^2}\\\\PQ=11\ units[/tex]
Distance between Q and R is :
[tex]QR=\sqrt{(4-4)^2+(6-(-6))^2}\\\\QR=12\ units[/tex]
Distance between R and S is :
[tex]RS=\sqrt{(4-6)^2+(-6-(-6))^2}\\\\RS=\sqrt{4}\\\\RS = 2\ units[/tex]
Therefore, total distance is 11 + 12 + 2 = 25 units.
Hence, this is the required solution.

patricia wants to have her living room carpet cleaned she found three different companies that would clean the carpet for $198 the companies are each offering discounts on their carpet cleaning services
Answer:
company 1 final price: $148.5
company 2 final price: $168
company 3 final price: $132
thus, the best choice is company 3 because it costs the least and all services are the same
Step-by-step explanation:
company 1 is offering 25% off the price of their service
company 2 is offering $30 off the price of their service
company 3 is offering a 1/3 discount off the price of their service
the price of the cleaning is $198
company 1: 25% discount = 75% of the original price $198, which would be $198 * 3/4, or $148.5
company 2: $30 dollars off, which means $198 - $30 or $168
company 3: 1/3rd discount, meaning the product after the discount is only 2/3rd of the original price. 2/3rd of $198 is $132, so the final price after the discount is $132

8x = 32
x=32/8 = 4
boys are 4 x 5 = 20
girls are 4 x 3 = 12
Step-by-step explanation:
Add the ratios together: 5 + 3 = 8
Divide total students by 8:
32 / 8 = 4
Multiply each ratio by 4 to find the number of each:
Boys = 4 x 5 = 20
Girls = 3 x 4 = 12

A company makes 130 bags.
49 of the bags have buttons but no zips.
32 of the bags have zips but no buttons.
39 of the bags have neither zips nor buttons.
A bag is selected at random.
What is the probability that the bag has buttons?
130-49 = 81
Answer 81/130
The probability that the bag has buttons is 0.38.
What is the probability?Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.
We know that, probability of an event = Number of favorable outcomes/Total number of outcomes.
Given that, a company makes 130 bags.
Here, the number of favorable outcomes = 49 and the total number of outcomes =130
Now, probability of an event = 49/130
= 0.38
Therefore, the probability that the bag has buttons is 0.38.
