Answer:
Kinetic energy = 2500 J
Step-by-step explanation:
To calculate the kinetic energy of an object, we can use the following formula:
[tex]\boxed{E_k = \frac{1}{2}mv^2}[/tex],
where:
[tex]E_k[/tex] = kinetic energy
m = mass of the object
v = speed of the object
In this question, we are told that Carlo's mass is 50 kg and his speed is 10 m/s. Using this information and the formula above, we can calculate Carlo's kinetic energy:
[tex]E_k = \frac{1}{2} \times 50 \times (10)^2[/tex]
[tex]= \frac{1}{2} \times 50 \times 100[/tex]
[tex]= \bf 2500 \: J[/tex]
Therefore, Carlo's kinetic energy is 2500 J.
Writing Explain how you can find the range of the inverse of f(x)=√x-1 without finding the inverse itself.
Domain of inverse of f(x)=√x -1 is [-1,∞),{x|x≥-1}
Range of inverse of f(x)=√x -1 is [0,∞),{y|y≥0}
Finding the Inverse Function but not the Inverse Function's Domain and Range
First, we must determine the domain and range of the original function f in order to determine the domain and range of an inverse function (x).
1.Find the function's domain and range.
Assume that the domain of the function f(x) is [0,∞),{x|x≥0}
Assume that the range of the function f(x) is [-1,∞),{y|y≥-1}
2. Substitute Domain for Range and Range for Domain
The domain of the calulated function f^-1(x) is [-1,∞),{x|x≥-1}
f^-1(x) calculated function (x) the interval for range is [0,∞),{y|y≥0}
∴Domain of inverse of f(x)=√x -1 is [-1,∞),{x|x≥-1}
Range of inverse of f(x)=√x -1 is [0,∞),{y|y≥0}

Slope intercept form (-6,19) and (3,-2)
Answer:
-7/3 or -2.3
Step-by-step explanation:
1. y2-y1 divided by x2-x1 which would be y2-y1/x2-x1
2. plug in : -2-19/3-(-6)
4. Solution ( -7.3 or -2.3 )
Answer:
[tex]y = -\dfrac{7}{3}x +5[/tex]
Step-by-step explanation:
The general equation of a line in slope-intercept form is
y = mx + b
where m = slope and b = y-intercept is rise over run
[tex]m = \dfrac {(y_{2} - y_{1})} {(x_{2} - x_{1})}[/tex]
where (x₁, y₁) and (x₂, y₂) are any two points on the line
For the line passing through (-6, 19) and (3, -2) , the slope
[tex]m = \dfrac{-2 - 19}{3 - (-6)}\\\\[/tex]
[tex]\\\\m= \dfrac{-21}{9}[/tex]
[tex]m = -\dfrac{7}{3}[/tex]
So slope-intercept form is
[tex]y = -\dfrac{7}{3}x +b\\\\[/tex]
To compute y-intercept, b, plug in any of the two points into the above equation and solve for b
Let's choose point (3, -2)
Plugging x = 3 and y = -2 gives
[tex]-2 = -\dfrac{7}{3}\cdot 3 +b\\\\\\\\-2 = -7 + b\\\\[/tex]
So equation of line is
[tex]y = -\dfrac{7}{3}x +5[/tex]

Putting together the solutions from each of the equations, the 4 letter code is GFBA
Solving Linear EquationsFrom the question, we are to solve each of the linear equations to determine the 4 LETTER CODE
1. -2x + 1 = 3x + 16
Add 2x to both sides
-2x + 2x + 1 = 3x + 2x + 16
1 = 5x + 16
Subtract 16 from both sides
1 - 16 = 5x + 16 - 16
-15 = 5x
x = -15/5
x = -3
The letter that corresponds to this is G
2. 7 - 8x = 4x - 17
Add 8x to both sides
7 - 8x + 8x = 4x + 8x -17
7 = 12x - 17
Add 17 to both sides
7 + 17 = 12x - 17 + 17
24 = 12x
x = 24/12
x = 2
The letter that corresponds to this is F
3. 20 -2(x - 2) = 2x
Clear the parentheses
20 -2x + 4 = 2x
Simplify
24 -2x = 2x
Add 2x to both sides
24 - 2x + 2x = 2x + 2x
24 = 4x

a group of friends are at a baseball game and are purchasing souvenirs. Lacey purchased 4 t-shirts and 2 baseball caps, spending a total of $162. Her Anna purchased 1 t-shirt and 2 baseball caps, which cost her a total of $93. Assuming that all of the t-shirts and all of the caps are the same price, what is the price of each?
The price of each souvenirs is 28.33 Dollars.
Let X be the same price of all the t-shirts and all the baseball caps.
Lacey purchased
4 T-shirts and 2 Baseball caps = $162
4X + 2X = $162
6X = $162
Anna purchased
1 T-shirt and 2 Baseball caps = $93
1X + 2X = $93
3X= $93
Now we will add the price of souvenirs purchased by Lacey and Anna to find the price each souvenir.
6X = $162 eq. 1
3X= $93 eq. 2
As we have two equations we will add both equations :
6X + 3X = $162 + $93
Then we will determine the value of X .
9X = $255
X = $255 ÷ 9
X = $28.33

What is Slope of a line?Slope of an straight line is denoted by m and is the measure of rate of change of 'y' with respect to 'x'. Mathematically -
m = tan(θ) = Δy/Δx
Given is a table representing a linear function. From the question, we can write -
X → 6 8 13 14
Y → -16 -24 -44 -48
We can find the slope of this line using the formula -
m = Δy/Δx
m = (y₂ - y₁) / (x₂ - x₁)
Take any two coordinates from the table -
(x₁, y₁) → (6, -16)
(x₂, y₂) → (8, -24)
Substitute the values in the formula -
m = (8 - 6)/(-24 + 16)
m = - 2/8
m = -1/4

How to Interpret Translation of line segments?In this question, the translations are defined by a line segment.
Such that in each translation, we can easily find the segment PQ (the measure and the direction).
And all the points in the Polygon P will be connected by that same segment PQ to the equivalent point in the Polygon Q. (where you only move the segment to the correct location, but the length and direction remains constant)
Thus, to find the line segment for each transformation, you need to correctly measure the length of the segment PQ, and also the direction (that can be defined by an angle).

P(t)=130t + P0
Find the Y-Intercept P0
The population function P(t) is measured since the year 1990, year zero. The first moose population was measured in 1992, one year later. This provides an initial condition P (1) = 4500.

The height of the tree is 15 feet if Scott is 6 feet tall and casts a shadow that is 8 feet long.
What is a scale factor?The ratio among comparable dimensions of an object and a model with that object is known as an exponent in algebra. The replica will be larger if the scale factor is a whole number. The duplicate will be lowered if the step size is a fraction.
It is given that:
Scott is 6 feet tall and casts a shadow that is 8 feet long. a nearby tree casts a show that is x+5 feet long
By using scale factor:
Let x be the height of the tree
x/6 = = (x + 5)/8
8x = 6(x + 5)
8x = 6x + 30
2x = 30
x = 15 feet
