Answer:
The reasonable domain for the scenario is option 'a';
a) [0, 7]
Step-by-step explanation:
For the projectile motion of the object, we are given;
The speed at which the object is launched, v = 29.4 meters per second
The height of the platform from which the object is launched, h = 34.3 meter
The equation for the height of the object as a function of time 'x' is given as follows;
f(x) = -4.9·x² + 29.4·x + 34.3
The domain for the scenario, is given by the possible values of 'x' for the function, which is found as follows;
At the height from which the object is launched, x = 0, and f(x) = 34.3
At the ground level to which the object can drop, f(x) = 0
∴ f(x) = -4.9·x² + 29.4·x + 34.3 = 0
-4.9·x² + 29.4·x + 34.3 = 0
By the quadratic formula, we have;
x = (-29.4 ± √(29.4² - 4 × (-4.9) × 34.3))/(2 × (-4.9)
∴ x = -1, or 7
Given that time is a natural number, we have the reasonable domain for the scenario as the start time when the object is launched, t = 0 to the time the object reaches the ground, t = 7
Therefore, the reasonable domain for the scenario is; 0 ≤ x ≤ 7 or [0, 7].

How to calculate the area of a square
Answer:
a × a × a ×a
Step-by-step explanation:
Area is measured in "square" units. The area of a figure is the number of squares required to cover it completely, like tiles on a floor.
Area of a square = side times side. Since each side of a square is the same, it can simply be the length of one side squared.
square has one side of 4 inches, the area would be 4 inches times 4 inches, or 16 square inches.
One of the legs of a right triangle measures 6 cm and the other leg measures 9 cm.
Find the measure of the hypotenuse. If necessary, round to the nearest tenth.

3x + 5
=
11
Solve for x:
3x + 5 = 11
DDDDD
Answer:
x = 2
Step-by-step explanation:
To solve this we first subtract 5 from both sides and get 3x = 6, now we divide both sides by 3 and we get x = 2.

Answer:
A function 2
Step-by-step explanation:
"Rate of change" in this context refers to the slope of the line.
Function 1
The slope of the line is the "rise" divided by the "run". That is, the vertical change between two points divided by the horizontal change between two points. Usually, we like to choose points where the line crosses gridline intersections. One of these is the y-intercept (0, -2). Another is 2 units right and 1 unit up at (2, -1).
The slope of function 1 is then ...
m = rise/run = 1/2
__
Function 2
The equation for function 2 is written in the "slope-intercept form." That is, the form is ...
y = mx + b . . . . . . . . where m is the slope and b is the y-intercept
Comparing this form to the given equation, we find ...
m = 5/2, b = -2
The slope is m = 5/2.
__
The slope of function 2 is 5/2. That is greater than the slope of function 1, which is 1/2.
Function 2 has the greater rate of change.
Line segment ON is perpendicular to line segment ML. Line segment OM = 13 units in length, line segment PN = 8 units in length. Circle O is shown. Line segments M O, N O, and L O are radii. Lines are drawn to connects points M and N and points N and L to form chords. A line is drawn from point M to point L and intersects line O N at point P. The length of O M is 13 and the length of P N is 8. Angle O P L is a right angle. What is the length of chord ML? 20 units 24 units 26 units 30 units
Answer:
24
Step-by-step explanation:
Line segment ON is perpendicular to line segment ML. Line segment OM = 13 units in length, line segment PN = 8 units in length.
Circle O is shown. Line segments M O, N O, and L O are radii. Lines are drawn to connects points M and N and points N and L to form chords. A line is drawn from point M to point L and intersects line O N at point P. The length of O M is 13 and the length of P N is 8. Angle O P L is a right angle.
The Length of the Chord ML is; 24 Units
What is the Length of the Chord?From the question, we are told that;
MO, NO and LO are radii.
Now, If MO = 13,then LO = NO = 13
However, if NO = 13 and NP = 8, It means that;
PO = NO - NP
PO = 13 - 8 = 5
With the aid of Pythagoras Theorem, we can find MP:
MP = √(MO² - PO²)
MP = √(13² - 5²)
MP = √(169 - 25)
MP = √(144)
MP = 12 units
Now, P is the midpoint of Segment ML, Thus;
MP = PL
ML = MP + PL
ML = 12 + 12
ML = 24 units

Sarah needs 3 feet of fabric for a project she is working on, but the store only sells the fabric in meters. One meter of fabric costs $1.20. How much will the fabric cost? [1 ft = 0.305 m]
Answer:
The 3 feet fabric will cost $ 1.09728 almost $ 1.10
Step-by-step explanation:
First we will find out how many meters 3 feet will be.
1 feet = 0.3048 meters
She needs 3 feet of fabric
3 *1 feet = 3* 0.3048 ( multiplying both sides by 3)
3 feet = 0.9144 meters
Using the unitary method we will find the cost of 3 feet of fabric
1 meter costs $ 1.20
0.9144 *1 meter costs $ 1.20 * 0.9144 ( multiplying both sides by 0.9144)
0.9144 meter = $ 1.09728
The 3 feet fabric will cost $ 1.09728 almost $ 1.10

we are given a 30-60-90 triangle and the longer side of the triangle
remember the properties of 30-60-90 triangle
the hypotenuse is twice as much as the shorter legthe longer leg is the square root of 3 times shorter legas we are given the longer leg we'll use the second property
let the shorter leg be x
so our equation is
[tex]\displaystyle x\sqrt{3}=16\sqrt{3}[/tex]
divide both sides by √3:
[tex]\displaystyle \frac{x\sqrt{3}}{\sqrt{3}}=\frac{16\sqrt{3}}{\sqrt{3}}[/tex]
[tex]\displaystyle x=16[/tex]
hence,
the length of the shorter leg is 16
