If a scale uses 2 centimeters to represent 5 feet, how many centimeters will be used to represent 17.5
feet?
A 7
B5
C 3.5
D7.5
Answer: The correct answer is D
Step-by-step explanation:
2 cen = 5ft
Multiply by 3 on both sides
6 cen = 15ft
multiply by .25
7.5 cen = 17.5ft

Find the Error A student graphs the relationship y = x on a coordinate plane. She says the slope is O because there is no coefficient. Find her
mistake and correct it.
Answer:
y=x times factor of 12 abstracted by -93
Step-by-step explanation:
The slope is the ratio of y's coordinate to x's coordinate thus the slope of y = x will be y/x = 1.
What is the slope?A slope is a tangent or angle at a point or a slope is the intensity of inclination of any geometrical lines.
Slope = Tanx where x will be the angle from the positive x-axis at that point.
A linear equation or function is given as ;
y = mx + b
Now,
At x = 0 ⇒ y = b so it will be a y-intercept.
As per the given, y = x
The x's coefficient is 1 thus slope will be 1.
Or, y/x = 1
Hence "The slope is the ratio of y's coordinate to x's coordinate thus the slope of y = x will be y/x = 1".

A square root function, that is stretched by a factor of 3, and shifted 4 units left and 6 units up.
Answer:
The square root function will turn to;
y = 3 √(x + 4) + 6
Step-by-step explanation:
Let the square root function be ;
y = √x
Now, let’s stretch this by a factor of 3
This means we are dilating by a factor of 3
Mathematically, this will be
y = 3 * √x = 3 √x
Shifting this 4 units up means that we are extending the x-axis value by 4 units
That will be ;
y = 3 √x + 4)
Now shifting this 6 units up, we finally will have;
y = 3 √(x + 4) + 6

The population of Luis’s city in 2005 was 7400 and the population in 2010 was 9000. Let x represent the number of years since 2005. Which linear equation, in slope-intercept form, represents the population, y, at a year since 2005, x, where y is in thousands.
Answer:
The linear equation is;
y = 320x + 7400
Step-by-step explanation:
Here, we want to write a linear equation that represents the population y at a year since 2005
To write this, we need points
Initially, we have (0,7400)
Since the difference between 2005 and 2010 is 5, the second point will be (5,9000)
Mathematically, we can get the slope as follows;
m = (y2-y1)/(x2-x1) = (9000-7400)/(5-0) = 1,600/5 = 320
The equation of the line can be represented using the general form as;
y = mx + b
where m is 320 and b is unknown
So we have the equation as;
y = 320x + b
we need to get b
To get b, we can use any point
let us use the point (0,7400)
substituting this;
7400 = 320(0) + c
c = 7400
so the equation is;
y = 320x + 7400

Select the correct answer from each drop-down menu. The velocity, v, in meters/second, of an object with a mass of m, in kilograms, and kinetic energy of K, in joules, is given by this equation. Use the equation to complete this statement. The kinetic energy of a ball with a mass of 2 kilograms that is rolling at a velocity of 5 meters/second is joules.
Answer:
25
Step-by-step explanation:
The kinetic energy of a ball with a mass of 2 kg that is rolling at a velocity of 5 m/s is 5 Joules
Calculating Kinetic energyFrom the question, we are to determine the kinetic energy of the ball
From the given equation for the velocity,
[tex]v = \sqrt{\frac{2K}{m} }[/tex]
We will make K the subject of the equation
[tex]v = \sqrt{\frac{2K}{m} }[/tex]
Take the squares of both sides
[tex]v^{2} ={\frac{2K}{m} }[/tex]
Multiply both sides by m
[tex]mv^{2} ={\frac{2K}{m} } \times m[/tex]
[tex]mv^{2} =2K[/tex]
∴ [tex]K = \frac{1}{2} mv^{2}[/tex]
Now, for the kinetic energy of a ball with a mass of 2 kilograms that is rolling at a velocity of 5 meters/second
That is,
m = 2 kg
and v = 5 m/s
Putting the parameters into the equation, we get
[tex]K = \frac{1}{2} \times 2 \times 5^{2}[/tex]
K = 25 J
Hence, the kinetic energy of a ball with a mass of 2 kg that is rolling at a velocity of 5 m/s is 5 Joules

Answer and Step-by-step explanation:
A. 4 inches: An object that's 4 inches is about 2.54 centimeters or 25.4 millimeters. An business envelope is typically about 4 inches by 9 inches for example.
B. 6 feet: A 6 feet object is quite big when compared to just 4 inches. A feet is 12 inches hence 6 feet is 72 inches. A very tall human being is typically 6 feet.
C. 1 meter: A meter is about 39.37 inches hence it is quite big when compared to a feet. A baseball bat is one meter long.
D. 5 yards: A yard is 36 inches hence a bit smaller than a meter. A trampoline could be 5 yards for example
E. 6 centimeters: one centimeter is 0.394 inches hence smaller than an inch. A 6 centimeters object for example is pencil for writing.
F. 2 millimeters: a millimeter is 0.0394 inches hence smaller than a centimeter and an inch. An orange seed could be 2 millimeters long
G. 3 kilometers: one kilometer is 39370.079 inches hence a kilometer is bigger than inches, meter, feet, yards, centimeters, millimeters. A very big tree could be 3 kilometers long
