Answer:
1) Zero based on (-16·t - 2) is t = -1/8 second
2) Zero based on (t - 1) is t = 1 second
Step-by-step explanation:
The given functions representing the height of the beach ball the child throws as a function of time are;
y = (-16·t - 2)·(t - 1) and y = -16·t² + 14·t + 2
We note that (-16·t - 2)·(t - 1) = -16·t² + 14·t + 2
Therefore, the function representing the height of the beachball, 'y', is y = (-16·t - 2)·(t - 1) = -16·t² + 14·t + 2
The zeros of a function are the values of the variables, 'x', of the function that makes the value of the function, f(x), equal to zero
In the function of the question, we have;
y = (-16·t - 2)·(t - 1) = -16·t² + 14·t + 2
The above equation can be written as follows;
y = (-16·t - 2) × (t - 1)
Therefore, 'y' equals zero when either (-16·t - 2) = 0 or (t - 1) = 0
1) The zero based on (-16·t - 2) = 0, is given as follows;
(-16·t - 2) = 0
∴ t = 2/(-16) = -1/8
t = -1/8 second
The zero based on (-16·t - 2) is t = -1/8 second
2) The zero based on (t - 1) = 0, is given as follows;
(t - 1) = 0
∴ t = 1 second
The zero based on (t - 1) is t = 1 second

At Norman's Newsstand, 5 magazines cost $20.00. How many magazines could you buy with $44.00?
Answers
Answer: 11 magazines
Step-by-step explanation:
1) 20/5 = $4 per magazine
2) 44/4 = 11 magazines
Answer:
10 magazines
Step-by-step explanation:
5 magazines cost $20.00
You have $44.00
If 5 magazines cost $20.00
Then 10 magazines would cost $40.00
Since the maximum amount of money you can spend is $44.00, you can only buy 10 magazines for $40.00 and be left with $4.00.

Reena bought a mobile phone for 16,240 that included a GST of 12%. Find the price of the mobile phone before the GST was added.
Person who answers will be marked brainliest
Answers
Answer: 14500
Step-by-step explanation:
Let the price of the mobile phone before the GST was added be represented by x.
Therefore,
x + (12% × x) = 16240
x + 0.12x = 16240
1.12x = 16240
x = 16240/1.12
x = 14500
The price of the mobile phone before the GST was added was 14500
At the grocery store, 6 pints of ice cream cost $14.40. How much would 40 pints of ice cream cost?
Answers
Answer:
$96
Step-by-step explanation:
14.40 / 6 = $2.40
$2.40 x 40 =
$96
Hope that helps!
The solution is $ 96
The cost of 40 pints of ice cream is given by the equation A = $ 96
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 cost of 40 pints of ice cream be A
Now , the equation will be
The cost of 6 pints of ice cream = $ 14.40
So , the cost of 1 pint of ice cream = cost of 6 pints of ice cream / 6
Substituting the values in the equation , we get
The cost of 1 pint of ice cream = 14.40 / 6
The cost of 1 pint of ice cream = $ 2.40
Now ,
The cost of 40 pints of ice cream A = 40 x cost of 1 pint of ice cream
Substituting the values in the equation , we get
The cost of 40 pints of ice cream A = 40 x 2.40
The cost of 40 pints of ice cream A = $ 96
Therefore , the value of A is $ 96
Hence , the cost is $ 96
