Mitch throws a ball over A 20 foot fence to a baseball field. The height, H, of the ball at the time T seconds after it was the round can be modeled by the equation H(t)=16^2 + 30t+6
which statement is true?
Answer:
(a) At 1.5 seconds, the ball is 15ft high
Step-by-step explanation:
Given
[tex]Fence:= 20ft[/tex]
[tex]h(t) := -16t^2 + 30t + 6[/tex]
Required
Select the true statement
See attachment for options
Option (a): At 1.5 seconds, the ball is 15ft high
This implies that:
[tex]t = 1.5[/tex]
Substitute [tex]t = 1.5[/tex] in [tex]h(t) := -16t^2 + 30t + 6[/tex]
[tex]h(1.5) = -16 * 1.5^2 + 30 * 1.5 + 6[/tex]
[tex]h(1.5) = -16 * 2.25 + 45 + 6[/tex]
[tex]h(1.5) = -36 + 45 + 6[/tex]
[tex]h(1.5) = 15[/tex]
This statement is true.
Because: [tex]h(1.5) = 15[/tex] means that:
At 1.5 seconds, the ball is 15ft high
Other options will not be checked because only one option can be correct

Answer: 49
Step-by-step explanation:
The missing constant term in the perfect square is 49.
x^2 + 14x + 49
We need a squart root of something to make the factor add up equal to 14x. If it's a perfect square, we could divide 14 by 2, 14/2 = 7, and we multiply 7^2, we get 49, which is a perfect square.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that John and his dad decide to order a pizza to eat while they are watching a World Cup Soccer game. John eats 2/5 of the pizza, and his dad eats 3/7 of the pizza.
The amount of pizza left will be calculated as below:-
Pizza left = 1 - ( 2/5) - (3/7)
Pizza left = ( 35 - 14 - 15 ) / 35
Pizza left = 6 / 35
Therefore, the amount of pizza left will be 6 / 35.

Maria decides to increase her homework time of 8 hours per week by 15% Calculate her new homework time. Give your answer in hours and minutes
Answer:
Maria's homework time is now 9 hours 12 minutes.
Step-by-step explanation:
Since Maria decides to increase her homework time by 15%.
Then,
15% of 8 hours = [tex]\frac{15}{100}[/tex] x 8 hours
= 0.15 x 8 hours
= 1.2 hours
(Note that: 1.2 hours = 1 hour 12 minutes)
15% of 8 hours = 1 hour 12 minutes
her new homework time = 8 hours + 1 hour 12 minutes
= 9 hours 12 minutes
Maria's homework time is now 9 hours 12 minutes.

Step-by-step explanation:
you are given the law of sines, in the question, so i'm guessing you don't get "law of sines" ???
some times I think people might just be lazy and they don't try, but I can understand if you really don't get "law of sines' b/c it is kinda abstract.
Any way here is how you solve this problem and please ask if you don't understand about something I do to solve this. Ask about it if you don't get it. :)

A shopkeeper paid $90 for 90 apples. He sold half of them for $3 each and the rest at $1 each.
Answer:
either $180 or $90?
Step-by-step explanation:
first i think you divide 90 by 2, which gives you 45. multiply 45 by 3, which is 135, then multiply 45 by 1, which is just 45. add those together and you get 180. i'm not too sure what you're looking for in the question, but if you're looking for the difference between what he bought them for, it'd be $90. if youre looking for how much he got from those apples, it's $180. hope that helps :)

Given the following data:
Adjacent side = 4 inches
Opposite side = 4 inches.
How to calculate the hypotenuse of a triangle?In order to calculate the hypotenuse of this triangle, we would apply Pythagorean theorem.
Mathematically, Pythagorean's theorem is given by this formula:
c² = a² + b²
Where:
c is the hypotenuse.a is the adjacent side.b is the opposite side.Substituting the given parameters into the formula, we have;
c² = 4² + 4²
c² = 16 + 16
c² = 32
c = √32 inches.

the number of days, d, that it will take to run a marketing campaign is given by d = 192/n where n is the number of people needed each day. alex’s company will take 32 days to run the campaign. shay’s company will take 24 days to run the campaign. shays company will have to use more people each day than alex’s company. how many more?
Answer:
2 more people each day.
Step-by-step explanation:
We are given the following relation:
[tex]d = \frac{192}{n}[/tex]
In which d is the number of days that will take to run a marketing campaign with n people.
Alex’s company will take 32 days to run the campaign.
So the number of people in his campaign is given by:
[tex]32 = \frac{192}{n}[/tex]
[tex]32n = 192[/tex]
[tex]n = \frac{192}{32}[/tex]
[tex]n = 6[/tex]
Shay’s company will take 24 days to run the campaign.
So the number of people in her campaign is given by:
[tex]24 = \frac{192}{n}[/tex]
[tex]24n = 192[/tex]
[tex]n = \frac{192}{24}[/tex]
[tex]n = 8[/tex]
Shays company will have to use more people each day than alex’s company. how many more?
8 - 6 = 2

Answer:
3(8+17)
Step-by-step explanation:
Since the gas prices are the same, we need to find a number that divides into both 24 and 51.
The factors of 24 are 1,2,3,4,6,8,12,24.
The factors of 51 are 1,3,17,51.
So, their common factor is 3. Price of gallon of gas = $3
Now we know the price, we can divide each total by 3 to find out how many each person bought.
One person bought $24 of gas: 24/3 = 8: They bought 8 gallons of gas
Another person bought $51 of gas: 51/3=17: They bought 17 gallons of gas
Represented as an expression, this is:
3(8+17)
Answer:
the correct answer to this is 3(8+17)
