units like radius, height, width, length or segments are single units, like meter or feet.
areas are double units, so they'd be in say meter² or feet².
volumes are triple units, namely like meter³ or feet³.
Answer:
The unit of measuring volume of the sphere is cubic meter.
Step-by-step explanation:
Given : Sphere with a radius of 2 meters.
To find : Which unit of measure would be appropriate for the volume of sphere.
Solution : We have given Radius = 2 meter .
Volume = [tex]\frac{4}{3}\pi (radius)^{3}[/tex].
Volume = [tex]\frac{4}{3}\pi (2 meter)^{3}[/tex].
Volume of sphere = [tex]\frac{32}{3}\pi[/tex] meter³ .
Therefore, The unit of measuring volume of the sphere is cubic meter.
Find the average rate of change from x = 3 to x = 15 for the function f(x) = 0.01(2)x and select the correct answer below
Plug values in function.
f(3) = 0.01(2)(3)
f(3) = 0.06
f(5) = 0.01(2)(5)
f(5) = 0.10
Average rate of change formula: f(b) - f(a) / b - a
Plug in.
0.10 - 0.06 / 5 - 3 = 0.04 / 2 = 0.02
Average rate of change: 0.02
Answer:
The Average rate of change: 0.02
Step-by-step explanation:
Great Question, First to be able to figure out the average rate of change for the function we need to plug each value for x given into the function and get an output value
[tex]f(3) = 0.01(2)(3)[/tex]
[tex]f(3) = 0.06[/tex]
[tex]f(15) = 0.01(2)(15)[/tex]
[tex]f(15) = 0.3[/tex]
Now that we have both outputs for the values of x given to us in the question, we can use the rate of change formula from the picture below to find the Rate of Change of these two values of x.
[tex]\frac{0.3-0.06}{15-3} = r[/tex]
[tex]\frac{0.24}{12} = r[/tex]
[tex]0.02 = r[/tex]
So Now we see that The Average rate of change: 0.02

Answer:
[tex]\frac{83}{186}[/tex]
Step-by-step explanation:
In probability, "OR" means "+" and "AND" means "*".
The total amount of people is:
32 + 54 + 78 + 112 + 96 = 372
Number of diabetic patients are 54
Number of eye patients are 112
Since we want "OR", we will add the two probabilities:
P(diabetic or eye problem) = 54/372 + 112/372 = 83/186

6. Chris can buy an online magazine
subscription for $5.99 per month or
$65 per year. How much will he save
by paying for the whole year at once
rather than one month at a time?
Answer:
$6.88
Step-by-step explanation:
We are trying to compare two options: Buying a magazine for 12 months or for just 1 year.
To solve this, we can multiply the monthly rate by 12 because there are 12 months in a year.
5.99 x 12 = 71.88
The other option is to just pay $65 dollars for a whole year (12 months).
Comparing the two options, we see paying for the whole year is cheaper than paying for each month individually. Because of this, we can subtract $65, the cheaper option, from $71.88 to get $6.88
Chris will save $6.88 by paying for the whole year instead of purchasing for each month.

8=8 is true
8 is the correct answer.
Infinitely many is the correct answer.
The given equation has no solution.
As the given equation is:
[tex]4s+8=3+5+4s\\[/tex]
So, if we simplify we get;
[tex]8=3+5+4s-4s[/tex] (subtracting 4s from both sides of the equation)
Now, on adding we get;
[tex]8=8[/tex]
So, LHS=RHS.
Therefore, there is no variable for which we can find the solution.
Hence option(b) none is the correct answer

, then what is the value of y
y
?
Answer:
y=-2
Step-by-step explanation:
y+3y+5y=−18
Combine like terms
9y = -18
Divide each side by 9
9y/9 = -18/9
y = -2
The equation y + 3y + 5y = -18 simplifies to 9y = -18; solving for y, we find y = -2.
Explanation:The equation presented is y + 3y + 5y = −18. To find the value of y, we first need to simplify the left-hand side of the equation by adding the similar terms together. In this equation, all terms on the left-hand side are multiples of y. Thus, y + 3y + 5y simplifies to 9y.
Our equation then becomes 9y = -18. To solve for y, we divide both sides of the equation by 9, yielding y = -2.
So, the value of y in this equation is -2.

For example, you need memoreize this group of side lengths of right triangle: 3 , 4 , 5
and in your options, there is a group is same as 3, 4 , 5 but it's 8 times bigger.
The answer is:
D. 24, 32, 40
Answer:

True or false? Many triangular shapes can be circumscribed about a given circle
Answer:
False.
Because Only one circle can be circumscribed about a given triangle.
Final answer:
The statement that many triangular shapes can be circumscribed about a given circle is true, as an infinite number of triangles can be formed by connecting any three distinct points on the circumference of the circle.
Explanation:
The statement "Many triangular shapes can be circumscribed about a given circle" is true. By definition, a circumscribed triangle is one that surrounds a circle, touching the circle exactly at its perimeter at three points.
Given a circle, you can indeed construct infinite triangles that circumscribe the circle, as for any set of three points on the circumference of the circle, a unique triangle can be formed.
In mathematical terms, three points determine one of these curves; that is, through any three points not in a straight line on a circle's circumference, we can draw a unique triangle which will circumscribe the circle.
Since there are an infinite number of points on a circle's circumference, we can choose an infinite number of triplets of points, each producing a different circumscribed triangle.

How do I find the inverse function of this equation
Answer:
y=ln(x/(1-x))
Step-by-step explanation:
y=e^x/(1+e^x)
Cross multiply
y(1+e^x)=e^x
Distribute
y+ye^x=e^x
Put anything with x on with side and everything without x on opposing side:
y=e^x-ye^x
Factor right hand side
y=(1-y)e^x
Divide both sides by (1-y)
y/(1-y)=e^x
Use natural log.
ln(y/(1-y))=x
The inverse is
y=ln(x/(1-x))

What is a parallelogram ?A parallelogram is a simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure.
How to find the value of x for which the figure is a parallelogram ?As we know that for a parallelogram, the opposite adjacent sides are always parallel and equal in length.
Therefore, for DEFG to be a parallelogram, the sides DH and FH must be equal in length.
We have, DH = FH
⇒ 4x - 2 = x + 28
⇒ 3x = 30
∴ x = 10
