By applying velocity concept, it can be concluded that the height of the object is 48 feet at 1 second and 3 seconds.
Velocity is the distance traveled, and the direction in which the distance is changing. It can also be described as the instantaneous rate of change of a moving object.
velocity = Δs / Δt , where:
Δs = distance change
Δt = time change
The height of the object is given by the equation h = -16t² + 64t.
We need to find the time t when the height is 48 feet.
To do this, we can plug in the value of h and solve for t:
h = -16t² + 64t
48 = -16t² + 64t
0 = -16t² + 64t - 48
Dividing by -16 gives us:
0 = t² - 4t + 3
= (t - 3)(t - 1)
Therefore, the possible values of t are 1 and 3 seconds.
So, the height of the object is 48 feet at 1 second and 3 seconds.

It will take 5.00 seconds for the object to reach a height of 48 feet.
To answer this question, we need to use the equation given: h = -16t2 + 64t. We know that the height is 48 feet and need to calculate the number of seconds it will take to reach this height.
We can rearrange the equation to solve for t, which will give us the number of seconds it takes to reach 48 feet:
48 = -16t2 + 64t
To solve for t, we can use the quadratic formula:
t = (-64 ± √(642 - 4(-16)(48))) / (2(-16))
After simplifying, we get:
t = (8 ± √384) / -32
Therefore, the two solutions are t = 5.00 seconds and t = -6.25 seconds.
Since the object is being propelled upwards, the only solution that makes sense is t = 5.00 seconds.
Therefore, it will take 5.00 seconds for the object to reach a height of 48 feet.

∠AFD = ∠DFC = 90° - perpendicular bisector theorem ....(7)
∠EAF = ∠EDF = 90° - Properties of the angles of a Quadrilateral
Since ∠EDC ≅ ∠FDB, as in (3) above, and
Both comprise of ∠EDF,
thus,
(∠EDC - ∠EDF) ≅ (∠FDB - ∠EDF)
Since
∠EDB = (∠FDB - ∠EDF); and
∠FDC = (∠EDC - ∠EDF)
Thus,
∠EDB ≅ ∠FDC
thus,
∠EDB = ∠FDC = 45° (Sum of Angles on a Straight line) that is
∠EDB = ∠FDC = (180° -∠EDF)/2
Since ∠EDF = 90°
∠EDB = ∠FDC = (180° -90°)/2
∠EDB = ∠FDC = 90/2
∠EDB = ∠FDC = 45°
Since
∠DEB = 90° (5); and
∠DFC = 90° (7)
ΔBED ≅ ΔDFC
Thus, by Sum of Angles in a Triangle,
∠B ≅ ∠C.
The perpendicular bisector theorem states that if a point lies on the perpendicular bisector of a line segment, then it is equidistant from the endpoints of the segment.The sum of angles theorem, also known as the triangle sum theorem, states that the sum of the interior angles of a triangle is always 180 degrees.The angles on a straight line theorem states that the sum of the angles formed by a straight line is always 180 degrees.The properties of the angles of a quadrilateral are: the sum of the angles is always 360 degrees, opposite angles are equal, and adjacent angles add up to 180 degrees.

Two parallel lines are cut by a transversal as shown below. Suppose m∠1=63°. Find m∠6 and m∠7.
Answer: Since lines l and m are parallel, we can use the fact that corresponding angles are congruent. Therefore:
m∠1 = m∠6 (corresponding angles)
m∠6 + m∠2 = 180° (supplementary angles, as angles 6 and 2 form a straight line)
m∠2 = m∠7 (corresponding angles)
m∠3 = m∠7 (alternate interior angles)
m∠1 + m∠4 = 180° (supplementary angles, as angles 1 and 4 form a straight line)
m∠3 + m∠4 = 180° (supplementary angles, as angles 3 and 4 form a straight line)
We know that m∠1 = 63°, so we can use the equations above to find m∠6 and m∠7:
m∠1 = m∠6, so m∠6 = 63°.
m∠6 + m∠2 = 180°, so m∠2 = 180° - m∠6 = 180° - 63° = 117°.
m∠2 = m∠7, so m∠7 = 117°.
m∠3 = m∠7, so m∠3 = 117°.
m∠1 + m∠4 = 180°, so m∠4 = 180° - m∠1 = 180° - 63° = 117°.
m∠3 + m∠4 = 180°, so m∠3 + 117° = 180°, which means m∠3 = 63°.
Therefore, the measures of the angles are:
m∠1 = 63°
m∠2 = 117°
m∠3 = 63°
m∠4 = 117°
m∠6 = 63°
m∠7 = 117°

Calculate the fluid intake in milliliters for the following meal
(assume a cup = 6oz and a glass = 8oz)
1/3 glass of orange juice
1/2 cup of tea
1/2 pt milk
1 tuna fish sandwich
1 popsicle (3oz)
TOTAL = _____ mL
*I need this answered quickly please and thank you.*
The total fluid intake for the meal is 493.04 mL.
How to find the total fluid intake for the meal?We first need to convert the volume of each beverage to ounces, and then to milliliters.
1/3 glass of orange juice = (1/3) x 8 oz = 2.67 oz = 79.01 mL (assuming 1 oz = 29.57 mL)
1/2 cup of tea = (1/2) x 6 oz = 3 oz = 88.72 mL
1/2 pt milk = (1/2) x 16 oz = 8 oz = 236.59 mL (assuming 1 pt = 16 oz and 1 oz = 29.57 mL)
1 popsicle (3oz) = 3 oz = 88.72 mL
The total fluid intake for the meal is
79.01 mL + 88.72 mL + 236.59 mL + 88.72 mL = 493.04 mL
Therefore, the fluid intake for the meal is approximately 493.04 mL.

Why do you use the word "binomial"?
A Binomial is a name for an algebraic equation with only two elements. It is a polynomial with two terms. It is also referred to as the total or difference of two or more binomials. It is a polynomial's most basic shape.
To expand and simplify the expression (√12 - √3)², we can use the formula for the square of a binomial:
(a - b)² = a² + b² - 2ab
In this case, a = √12 and b = √3, so we have:

Answer:
m<BFC= 64°; m<AFB= 116°
Step-by-step explanation:
Using the Vertical Angle Theorem, in which "the opposing angles of two intersecting lines must be congruent, or identical in value"
m<AFE is congruent to m<BFC, therefore m<BFC is 64°
You can also use the straight angle theorem where BE is a straight line, and is therefore 180°. so subtracting 180° from 64° will result in m<AFB being 116°, you second answer. You can take it a step further without using the vertical angle theorem to get our first answer by using the same rules for the straight angle theorem again, knowing that AC is a straight line and that m<AFB is 116°, subtract 180° by 116° to get m<BFC, 64°.

Kenneth is making a shelf that requires 2 & 7/10 feet of lumber. He has 5/8 feet of lumber. How much more lumber does he need?
If Kenneth has 5/8 feet of lumber, then he need 83/40 feet of lumber to make the shelf.
First we convert the length of lumber in improper fraction form,
So, we convert 2(7/10) feet to an improper fraction,
⇒ 2(7/10) = (2×10 + 7)/10 = 27/10,
To find the length of lumber required we need to subtract the amount of lumber Kenneth has from the total length required,
Kenneth has a total of 5/8 feet of lumber,
Length of lumber required is = 27/10 - 5/8,
Taking LCM of 10 and 8 as 40 , and simplifying further,
We get,
⇒ 108/40 - 25/40
⇒ 83/40

The difference between the starting amοunt and the amοunt at the end οf the day is:
100 - 87.06 = 12.94
Tο express this as a percentage οf the starting amοunt, we divide this difference by the starting amοunt and multiply by 100:

The ratio of horizontal distance to height of the ramp is 27:2. A builder has a roll of non-slip rubber
mat that is 27 feet long. Does he have enough rubber to cover the ramp completely? Explain.
Answer:
Yes
What is horizontal distance ?
The distance between two points is understood to mean the horizontal distance, regardless of the relative elevation of the two points.
How to calculate horizontal distance?
Horizontal distance can be expressed as x = Vtx = Vtx=Vt. Vertical distance from the ground is described by the formula y = – 1 2 g t 2 y = – \frac{1}{2}g t^2 y=–21gt2, where g is the gravity acceleration, and h is an elevation.
Step by step explanation:
As long as the ramp is no more than .9965 feet high, then yes
If the ramp is .9965 feet high then its horizontal distance is 12 X .9965 feet or 11.958 feet
Using Pythagoras’ Theorem, the actual length of the ramp would be the square root of (11.958 X 11.958 + .9965 X .9965)
Or the square root of (142.9934 + .9930)
Or SQRT (143.987)

Which statement supports the correct answer from Part A?
A. As x increases by 1, the value of f (x) is squared.
B. As x increases by 1, the value of f (x) increases by a factor of 6.
C. As x increases by 1, the value of f (x) increases by a constant value.
Part A: The function f(x) is an exponential function.
Part B: As x increases by 1, the value of f(x) increases by a factor of 6.
How to explain the functionIt is an exponential function because the function is of the form f(x) = a^(x-1), where a is a constant. We can see that when x increases by 1, the exponent in the function increases by 1 as well. So we have:
f(x+1) = a^x * a
f(x) = a^(x-1)
Therefore, the ratio of f(x+1) to f(x) is:
f(x+1)/f(x) = (a^x * a) / (a^(x-1)) = a
This means that as x increases by 1, the value of f(x) increases by a factor of a, which in this case is 6. Therefore, statement B supports the correct answer from Part A.

The country of Sylvania has decided to reduce the number
3
of its illiterate citizens by
5 each year. This year there are
9000 illiterate people in the country.
Write a function that gives the number of illiterate people in Sylvania, P(t), t years from today.
The functiοn that gives the number οf illiterate peοple in Sylvania is
[tex]\mathrm{P(t) = 9000(2/5)^t}[/tex]
What are functiοns in mathematics?A functiοn is defined as a relatiοn between a set οf inputs, each with an οutput. Simply put, a functiοn is a relatiοnship between inputs, each assοciated with exactly οne οutput. Each functiοn has a dοmain and cοdοmain οr scοpe.
Hοw tο identify relatiοn and functiοn?Tο identify a functiοn frοm a relatiοn, check if any οf the x values are repeated. If it's nοt repeated, it's a functiοn. If the x values are repeated and the cοrrespοnding y values are different, it's nοt a functiοn but a relatiοn.
Sοlutiοn accοrding tο the questiοn:
Given, Tοtal number οf illiterate peοple = 9000
Amοunt = 3/5
Fοr the first year = 9000 × (1 - 3/5) = 9000(2/5)
Nοw, fοr "t years":
P(t) = 9000(2/5)
