Answer:
77 ft
Step-by-step explanation:
The horizontal distance is the range and it is a projectile motion.
So, range R = u²sin2θ/g where u = velocity = 50 ft/s, g = acceleration due to gravity = 32 ft/s² and θ = projection angle = 40°.
Substituting the values of the variables into the equation, we have
R = u²sin2θ/g
= (50 ft/s)²sin2(40°)/32 ft/s²
= (2500 ft²/s²)sin80°/32 ft/s²
= (2500 ft²/s²) × 0.9848/32 ft/s²
= 2462.02 ft²/s² ÷ 32 ft/s²
= 76.94 ft
≅ 77 ft to the nearest foot

Four friends are on a basketball team. During a game, each friend kept track of how many shots they attempted and how many of those attempts they made. Henry made 0.45 of his shots. Allison made 4/15 of her shots. Arthur made 8/20 of his shots. Trevor missed 58% of his shots. Which friend had the best record for the number of shots made?
Answer:
Henry has a best record for the number of shots made.
Step-by-step explanation:
It is provided that Henry made 0.45 or 45% of his shots.
And Trevor missed 58% of his shots, i.e. Trevor made 42% of his shots.
There is no information about Allison's and Arthur's probability of making the shot.
So, only based upon Henry and Trevor, it can be seen clearly that Henry has a best record for the number of shots made.

Is it linear or exponential
Linear is a straight line. You might have heard of Linear Function.
[tex]y = mx + b[/tex]
The equation above is slope-intercept form.
ExponentialExponential is both increasing graph and decreasing graph depending on the coefficient.
Exponential Equation
[tex]y = {a}^{x} \: \: \: (a > 0) \: \: (a \neq1)[/tex]
Exponential Graph increases when a-term is greater or equal to 1.
Exponential Graph decreases when a-term is greater than 0 but less than 1.
From the equation, it is exponential of x-term as an exponent. The equation matches with exponential form.

Answer:
[tex](c)\ \frac{6}{5}[/tex]
Step-by-step explanation:
The question is incomplete as it has missing options.
See attachment for complete question and options..
From the attachment, we have:
[tex](a)\ \frac{-7}{9}[/tex]
[tex](b)\ \frac{-8}{2}[/tex]
[tex](c)\ \frac{6}{5}[/tex]
[tex](d)\ \frac{3}{-2}[/tex]
All but 6/5 are negative numbers.
This is so because:
[tex](a)\ \frac{-7}{9}[/tex] has a negative sign at the numerator
[tex](b)\ \frac{-8}{2}[/tex] has a negative sign at the numerator
[tex](d)\ \frac{3}{-2}[/tex] has a negative sign at the denominator
Only [tex](c)\ \frac{6}{5}[/tex] has positive integers at the numerator and denominator.
Find the coordinates of the midpoint for line segment JK if J(-9, 5) and K(21.-7)
Answer:
(6, -1)
Step-by-step explanation:
The coordinates of the midpoint of a line is [(x₁ + x₂)/2, (y₁ + y₂)/2]. For the given line, JK where J = (-9, 5) = (x₁, y₁) and K = (21,-7) = (x₂, y₂).
So [(x₁ + x₂)/2, (y₁ + y₂)/2]
= [(-9 + 21)/2, (5 + (-7))/2]
= [12/2, (5 - 7)/2]
= [12/2, -2/2]
= (6, -1)

Rectangle ABCD has a length represented by the expression 2x - 3, and a width
represented by the expression 4x + 5. Rectangle PQRS has a length represented by
the expression x - 1, and a width represented by the expression 3x + 2. Which are used to represent the difference in the perimeters of
Rectangle ABCD and Rectangle PQRS
Answer:
Perimeter of ABCD - Perimeter of PQRS = 4x + 2
Step-by-step explanation:
i. For rectangle ABCD;
length, l = 2x -3
width, w = 4x + 5
Perimeter of a rectangle = 2(l + w)
Perimeter of ABCD = 2((2x -3) + (4x + 5))
= 2(2x -3 + 4x + 5)
= 2(6x + 2)
Perimeter of ABCD = 12x + 4
ii. For rectangle PQRS;
length, l = x - 1
width, w = 3x + 2
Perimeter of a rectangle = 2(l + w)
Perimeter of PQRS = 2((x - 1) + (3x + 2))
= 2(x - 1 + 3x + 2)
= 2(4x + 1)
Perimeter of PQRS = 8x + 2
So that,
Perimeter of ABCD - Perimeter of PQRS = (12x + 4) - (8x + 2)
= 12x + 4 - 8x - 2
= 4x + 2
Perimeter of ABCD - Perimeter of PQRS = 4x + 2
2(3x-4)=(x+37)

Answer:

Step-by-step explanation:
Knowing the first triangle is isosceles, and given the degree is 69.
We can find the top left angle as 180-69-69=42
42 combine with another angle to make a right angle
90-42=48.
The second triangle is also isosceles, so to find 2
we can use 180-42=138 (supplementary angles rule)
and given 10x-8=138
10x=140
x=14

The cost of hiring a taxi consists of a fixed cost of $3 plus $0.5 per kilometer distance travelled. Write an expression in terms of y for hiring a taxi for y kilometers.
Answer:
The required expression is:
y = 0.5x + 3Please check the attached graph too.
Step-by-step explanation:
The slope-intercept form of the linear or line function
[tex]y = mx+b[/tex]
where
m is the rate of change or slopeb is the y-interceptIn our case,
The cost of hiring a taxi consists of a fixed cost of $3. It means the fixed cost of $3 is the initial condition.
Thus, the y-intercept b = 3
It is stated that the cost of per kilometer distance = $0.5
Thus, the rate of change or slope m = 0.5
As y represents the cost and x represents the number of kilometers.
so substituting m = 0.5 and b = 3 in the slope-intercept form of the linear or line function
y = mx+b
y = 0.5x + 3
Thus, the required expression is:
y = 0.5x + 3Please check the attached graph too.

The tape diagram models the lengths of two snowboarding trails. The expert trail is 1200 meters long. How long is he beginner trail?
Answer:
300 ft long
Step-by-step explanation:
divide 1200 by 4 sense the beginners trail is one-fourth the length of the expert trail
The length of beginner trail is 300 meter long.
What is Division method?Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;
The tape diagram models the lengths of two snowboarding trails.
And, The expert trail is 1200 meters long.
Now, The length of beginner trail is,
⇒ 1200 / 4 meter
⇒ 300 meter
Thus, We get;
⇒ The beginner trail is 300 meter long.

A circular piece of wood with a diameter of 5 ft is shown below. A 2 ft square is
cut out of the middle of the piece of wood.
2 ft
What is the approximate remaining area of the wood?
O A. 21 ft2
O B. 16 ft2
O C. 18 ft2
OD 28 ft2
Answer:
16 ft²
Step-by-step explanation:
Since we're told that 2 ft diameter was cut of the board. We use the formula for hollow circle to find the area.
Area of remaining body = area of full body - area of removed body.
Area = πd²/4
Area of remaining body = (π * 5²)/4 - (π * 2²)/4
Area of remaining body = 19.64 - 3.142
Area of remaining body = 16.49 ft²
Therefore, the remaining area is then calculated into 16 ft²
