When an object is thrown upwards with a speed of 64 ft/sec, its height above the ground is given by the function h(t)=−16t2+64t , where t is the time in seconds after it has been thrown. At what time will the object reach its highest point?
Answer:
The object will reach its highest point 0.5 seconds after it has been thrown.
Step-by-step explanation:
The object reaches its maximum height when velocity is equal to zero, the velocity is the derivative of function height. That is:
[tex]v(t) = \frac{d}{dt}h(t)[/tex] (1)
Where [tex]v(t)[/tex] is the velocity of the object at time [tex]t[/tex], in feet per seconds.
If we know that [tex]h(t) =-16\cdot t^{2}+64\cdot t[/tex] and [tex]v(t) = 0\,\frac{ft}{s}[/tex], then the time when object reaches its highest point is:
[tex]v(t) = -32\cdot t+64[/tex]
[tex]-32\cdot t + 64 = 0[/tex]
[tex]t = 0.5\,s[/tex]
The object will reach its highest point 0.5 seconds after it has been thrown.

Mr and Mrs Boyden take their 3 children to a leisure park.
they buy tickets for the whole family.
the cost of an adult ticket is £6 more than the cost of a child ticket.
the total cost of the five tickets is £82
Step-by-step explanation:
2 adults & 3 children
1 adult's ticket is €6 more than a child's ticket
1 child's ticket = 82 - 2 adults(€6 × 2 =€12)
= 82 - 12= €70
: 70÷5 = 5_/70
12 = €12
Therefore 1 Child's Ticket Is €12
And 1 Adult's Ticket Is = 12 + 6= €18
Total Cost = 18 + 18 + 12 + 12 + 12 = €82
Find the area of the sector.
44.66 in^2
11.16 in^2
2.8 in^2
50.24 in^2
Answer:
11.16in^2
Step-by-step explanation:
Area of a sector = theta/360 * πr²
Area of a sector = 80/360 * 3.14*4²
Area of a sector = 8/36 * 50.24
Area of a sector = 401.92/36
Area of a sector = 11.16in^2
Hence the Area of the sector is 11.16in^2

For each carbon-14 atom, there are approximately 10^12 carbon-12 atoms. This ratio is constant in each organism. The carbon-12 remains constant but the carbon-14 decays. Suppose a piece of wood is analysed, and it contains 10^14 carbon-12 atoms and 40 carbon-14 atoms.
1) Determine how many carbon-14 atoms were present in the wood when it died.
2) Use the half life of carbon-14 atoms to obtain a function to model the number N of carbon-14 atoms present in the wood (t) years after it died
Answer:
1) There are 100 carbon-14 atoms in the wood when it died
2) A function that models the number 'N' of carbon-14 atoms present in the wood (t) years after it died is presented as follows;
[tex]N = 100 \times \left (\dfrac{1}{2} \right )^{\dfrac{t}{5,730} }[/tex]
Step-by-step explanation:
The given parameters are;
The number of carbon-12 for each carbon-14 atom ≈ 10¹² carbon-12 atoms
The number of carbon-12 in the piece of wood = 10¹⁴ carbon-12 atoms
The number of carbon-14 in the piece of wood = 40 carbon-14 atoms
The number of carbon-12 in an organism = Constant
The number of carbon-14 in an organism = Decays
1) Given that the number of carbon-12 in an organism is constant, and there are 10¹² carbon-12 atoms per each carbon-14 atom, therefore, we have;
The number of carbon-12 atoms in the wood when it died = 10¹⁴ carbon-12 atoms
The number of carbon-14 atoms in the wood when it died = (10¹⁴ carbon-12 atoms)/(10¹² carbon-12 atoms/(carbon-14 atom)) = 100 carbon-14 atoms
The number of carbon-14 atoms in the wood when it died = 100 carbon-14 atoms
2) The half life of a radioactive isotope is given by the following formula;
[tex]N(t) = N_0 \cdot \left (\dfrac{1}{2} \right )^{\dfrac{t}{t_{\frac{1}{2} }} }[/tex]
The half life of carbon-14 atoms, [tex]t_{\frac{1}{2} }[/tex] ≈ 5,730 years
N₀ = The amount of carbon-14 present in the wood when it died = 100 carbon-14 atoms
Therefore, we have;
The number, N, of carbon-14 atoms present in the wood (t) years after it died is given as follows;
[tex]N = 100 \times \left (\dfrac{1}{2} \right )^{\dfrac{t}{5,730} }[/tex]
What is an equation of a the line through (-1, -4) and parallel to the line 3x+y=5
Answer: y + 4 = -3(x+1)
Step-by-step explanation:
We need to rewrite in form of y=mx+b.
3x+y=5
y = -3x + 5
The slope is -3.
In addition, the slope of two parallel line would be equal, the slope of the line would be -3.
y- y1 = m(x- x1)
y- (-4) = -3(x - -1)
y + 4 = -3(x+1)

Find the mistake and show the correct steps and solution
Answer:
The mistake happens in the 4th line.
Step-by-step explanation:
The first 3 lines are correct until the 4th line which is 2=6x. This is wrong. If we go back a line to the third line, it is 22=-20+6x. The part that was wrong was that they subtracted 20 from 22 to get 2. We are supposed to add 20 to each side because the -20 is negative. So the 4th line should be 42=6x. Then, we know that 6 times 7 is 42, so x is equal to 7.
22 + 53x + x = -20 + 60x
22 + 54x = -20 + 60x
22 = -20 + 6x
42 = 6x
x = 7

John took a taxi from his house to the airport. The taxi company charged a pick-up fee of $4.70 plus $2.50 per mile. The total fare was $24.70, not including the tip. How many miles was the taxi ride?
Answer:
8
Step-by-step explanation:
You can solve this by creating a linear equation.
Slope: 2.50
Y-intercept: 4.70
y=2.50x+4.70
Since we know that the total fare was 24.70 we can plug it into the y.
24.70=2.50x+4.70
Now solve for the equation.
20=2.50x
8=x
So he went 8 miles with the taxi.
Total number or mile taxi run is 8 miles.
Given that;
Pick up charge = $4.7
Charges per mile = $2.5 per mile
Total fare = $24.7
Find:
Number of mile taxi ride
Computation:
Total fare = Pick up charge + [Total number or mile taxi run][Charges per mile]
24.7 = 4.7 + [Total number or mile taxi run][2.5]
[Total number or mile taxi run][2.5] = 24.7 - 4.7
[Total number or mile taxi run][2.5] = 20
Total number or mile taxi run = 20 / 2.5
Total number or mile taxi run = 8 miles

Elise bought a dress that was discounted 35% off of
the original price of $140. What was
a: the amount of discount and
b : the sale price of the dress?
Answer:
a: $49
b: $91
Explaination:
a: 35% of 140 = 49
b: 140 - 49 = 91
You're welcome! <3
The amount of discount is $49 and the sale price of the dress is $91 and this can be determined by using the unitary method.
Given :
Elise bought a dress that was discounted 35% off of the original price of $140.
a) The unitary method can be used in order to determine the amount of discount. If the original price is $140 then the discounted price is given by:
[tex]=\dfrac{35}{100}\times 140[/tex]
Simplify the above expression.
= $49
b) The unitary method can be used in order to determine the sale price of the dress. If the original price is $140 then the selling price is given by:
[tex]=\dfrac{65}{100}\times 140[/tex]
Simplify the above expression.
= $91
