The maximum height attained by the arrow will be 1,700 feet.
What is mean by Quadratic equation?
A polynomial which has a power two then its called a Quadratic equation.
Given that;
An arrow is launched upward with a velocity of 320 feet per second from the top of a 100-foot structure.
Let the equation for the height of the arrow at time t is;
h (t) = - 16t² + 320t + 100.
Here, The arrow is follow the path of a parabola that curves downwards.
The value of t for the vertex = - b / 2a
= - 320/2×-16
= 10
Substitute t = 10 in above equation, we get;
h (t) = - 16t² + 320t + 100.
h (t) = - 16 × 10² + 320 × 10 + 100
h (t) = -16 × 100 + 3200 + 100
h (t) = - 1600 + 3200 + 100
h (t) = 1,700
Therefore, The maximum height attained by the arrow will be 1,700 feet.

Please help! In a tidal river, the time between high and low tide is 5.8 hours. At high tide, the depth of water is 17.2 feet, while at low tide the depth is 4.6 feet. Assume the water depth as a function of time can be expressed by a trigonometric function (sine or cosine).
Write an equation for the depth () of the tide (in feet) hours after 12:00 noon.
Answer:
Step-by-step explanation:
mean tide is (17.2 + 4.6)/ 2 = 10.9 ft
Amplitude of tide is (17.2 - 4.6)/ 2 = 6.3 ft
The full tide cycle is 2(5.8) = 11.6 hrs
As we are not told the tide condition at 12:00 noon,
I will ASSUME that the tide is high and use the cosine function
D = 10.9 + 6.3cos(2π(t/11.6)) ft
where t is in hours after noon high tide.
make sure your calculator is set to radians.
If you want to use degrees, the equation becomes
D = 10.9 + 6.3cos(360(t/11.6)) ft

Jacob sells homemade skateboard decks profit $27 per deckHe is considering switching a new type of material as expressed by the function y = 32x, where x is the number sold and y is the amount of How many more dollats will Jacob on skateboard deck if he switches to the new material? Explain how you found your answer
Answer:
I believe it is 32
Step-by-step explanation:
I think this because in your equation it says (y=32x) which 32 will mean how much he is charging for each skateboard, x will be how many he sells, and y would be how much he makes from selling them. So if he sold 2 skateboards you would do.. 32 x 2 which equals 64 soo that would be (64=32x2) so it is 32

A chemist want to mix a 40% acid solution with a 70% acid solution to make 6 liters of a 50% acid solution. How much of each type of solution should the chemist use? Show your Work. I NEED HELP ASAP, PLZ HELP
Answer:
2 liters of 70%
4 liters of 40%
Step-by-step explanation:
Let
x = liters of 70%
Then the remaining amount is
6 - x = liters of 40%
---------------------------------
Mixing
(70% of x) + (40% of 6 -x) (to get) 50% of 6)
70(x) + 40(6-x) = 50(6)
Simplify
70x + (240 - 40x) = 300
Combine like terms
30x = 60
Divde both sides by 30
x = 2 liters of 70%
6 - x = 4 liters of 40%

This graph shows how fast the Shanghai Maglev train travels on its route in
China.
What is the meaning of the point with an x-coordinate of 2?
Answer:
D
Step-by-step explanation:
the x (horizontal) axis is for time passed in seconds.
the y (vertical) axis is for distance traveled in meters.
so, x = 2 means 2 seconds.
now, move straight up at this point until you meet the line. from there go straight to the left until you hit the y/distance axis. what number is there ? 140. meaning 140 meters.
so, the train travels 140 meters in 2 seconds.
An angle measures 4.6° less than the measure of its supplementary angle. What is the measure of each angle?
Answer:
The two angles are,87.7° and 92.3°Step-by-step explanation:
Question,To find an angle and it's supplementary angle.
Let,The supplementary angle be = x
So, the angle given is = x - 4.6
As we know,When two angles added gives 180°, then those angles are called supplementary angles.
Therefore solution,By the problem,
=> x + (x - 4.6) = 180
[On adding like terms x]=> 2x - 4.6 = 180
[Putting - 4.6 to other side of equal to which converts to 4.6]=> 2x = 180 + 4.6 = 184.6
[On dividing 2 on both sides][tex] = > \frac{2x}{2} = \frac{184.6}{2} [/tex]
[On Simplification]=> x = 92.3
Result:So, the supplementary angle is = 92.3° (Ans)(ii)
And, it's required angle is = 180° - 92.3° = 87.7° (Ans)(i)
Supplementary Angles :
If the sum of the measures of two angles is 180°, then the angles are called supplementary angles and each angle is called a supplement of the other.⠀
Given :
An angle measures 4.6° less than the measure of its supplementary angle.⠀
To Find :
The measure of each angle.⠀
Solution :
Let's assume the one of the supplementary angle as "x" and the other angle as (x + 4.6)° .Now,
According to the Question :
[tex]\begin{gathered}\\ \sf x + (x - 4.6) {}^{ \circ} = 180{}^{ \circ} \\ \\ \dashrightarrow \: \sf x + x - 4.6{}^{ \circ} = 180{}^{ \circ} \\ \\ \sf \: \dashrightarrow 2x - 4.6{}^{ \circ} = 180{}^{ \circ} \: \: \: \: \\ \\ \dashrightarrow \sf \: 2x = 180{}^{ \circ} + 4.6{}^{ \circ} \\ \\ \dashrightarrow \sf \: 2x = 184.6{}^{ \circ} \: \: \: \: \: \: \: \: \\ \\ \dashrightarrow \: \sf \: x = \frac{184.6 {}^{ \circ} }{2} \: \: \: \: \: \\ \\ \dashrightarrow \: \sf \: x = 92.3 {}^{ \circ} \: \: \: \: \: \\ \\\end{gathered}[/tex]
Therefore,
One angle = 92.3°Other angle = 180° – 92.3° = 87.7°⠀
Hence,
The measure of the two angles are 92.3° and 87.7° .In the xy-coordinate plane shown, line L passes through point C and has a slope of -2. A dilation of line {with center A and a scale factor of 3 will
produce a new line through point C'the image of point C,
with coordinates
and with a slope of
The solution is, New line slope will be -2 and, coordinates (-4. 2).
What is slope?In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).
here, we have,
Dilation of a line about a point not on the line shifts the line but leaves the slope intact .
New line slope will be -2
As both A and C lie on a horizontal line y = 2, C' will also lie on the same line
The distance between A and C is 0 - 2 = -2
a scale factor of 3 means C' is -2(3) = -6 units left of A
C' = (2 - 6, 2)
= (-4. 2)
Hence, The solution is, New line slope will be -2 and, coordinates (-4. 2).

$2/5lb find unit rate
Answer:
1$/2.5lb
Step-by-step explanation:
This is a fraction equal to 5 pounds / 2 dollars
We want a unit rate where 1 is in the denominator, so we have to divide the top and bottom by 2.
5 pounds / 2
2 dollars / 2
This should progress to
2.5 pounds/a dollar
This means that the unit rate is 2.5 pounds per dollar.
