Answer:

The unit rate for her riding in miles per hour is given by 2 miles per hour.

Step-by-step explanation:

Amber rides m miles in h hours according to the equation m=2h .......... (1)

Putting h = 1 hour, we get m = 2 miles.

Therefore, Amber rides 2 miles height within a period of time 1 hour.

Therefore, the unit rate for her riding in miles per hour is given by 2 miles per hour. (Answer)

Again, differentiating equation (1) with respect to h we get,

[tex]\frac{dm}{dh} = 2[/tex] miles per hour.

So, here also we get the unit rate of her riding is 2 miles/hr.

Step-by-step explanation:

Point B(2, 8) reflect to x-axis

It means the x value won't change, the only thing that will change is the y value.

According to it, we can know that B' is (2, -8)

(2, -8) → (-8, 2+4) = (-8, 6) = B''

Final answer:

To obtain the coordinates of B'' after a reflection across the x-axis and a translation of (x,y)
ightarrow(y,x+4), point B(2,8) becomes B'(2,-8) after reflection and then B''(-8, 6) after translation.

Explanation:

The student is asking about the results of performing a geometric transformation on a point in the coordinate plane. Specifically, point B(2,8) is first reflected across the x-axis, and then is translated according to the rule (x,y)
ightarrow(y,x+4). To find the coordinates of B'', we follow these steps:

Reflect B across the x-axis: The x-coordinate remains the same, but the y-coordinate changes sign, resulting in B'(2,-8).

Apply the translation rule: We then take the coordinates of B' and apply the rule. The x-value of B' becomes the y-value of B'' and the y-value of B', decreased by 4, becomes the new x-value. Therefore, B'' = (-8, 2+4) = (-8, 6).

The final coordinates of B'' after the reflection and translation are (-8,6).

The true statements are:

A. Tree A's heights are less spread out than tree B's heights and

B. Tree A has lower average height than tree B

Explanation:

Standard deviation in this case represents the spreading out of heights of the trees, Since tree A has lesser standard deviation given equal to 5 , it is less spread out than B given equal to 12, hence option A. is true.

The average of a quantity is given by mean so, the average height can be compared by the given mean values of the trees. Since, A has lesser mean value (= 25) than B(=60), tree A is said to have lower average height than tree B hence option B. is true.

Answer:

1/256

Step-by-step explanation:

1/256

4^-4 as a fraction is 1/256. It cannot be further simplified because 1 and 256 have no common factors other than 1, making it the simplest form.

To express 4^-4 as a fraction and simplify it, we can apply the rule that states any non-zero number raised to a negative exponent is equivalent to 1 divided by that number raised to the positive exponent.

So, for 4^-4, we can write it as:

4^-4 = 1 / 4^4

Now, let's calculate 4^4:

4^4 = 4 * 4 * 4 * 4 = 256

So, we have:

4^-4 = 1 / 256

This is the fraction representation of 4^-4. To determine if it can be further simplified, we can check if the numerator and denominator have any common factors other than 1. In this case, 1 and 256 have no common factors other than 1.

Therefore, 1/256 is already in its simplest form. It represents the fraction equivalent of 4^-4, which is a small value. It means that 4 raised to the power of -4 is a very small positive number, specifically 1/256, indicating that the original number 4^-4 is less than 1 and quite close to zero in value.

Step-by-step explanation:

Hence, the actual distance between Paige's house and the mall is [tex]21[/tex] miles.

What is the simplification?

Simplification is reducing the expression/fraction/problem in a simpler form. It makes the problem easy with calculations and solving.

Here given that,

Step-by-step explanation:

A function assigns the values. The right-hand limit of this function at x=2 is -1.

A function assigns the value of each element of one set to the other specific element of another set.

The right-hand limit of the function when the value of x=2, can be found by substituting the value of x as 2 in the given function, therefore, the right-hand limit of this function at x=2 is,

g(x) = (x²-3)/(x-3)

g(2) = (4-3)/(2-3)

g(2) = -1

Let Y=set of all even numbers

that is [tex]Y={\{2,4,6,8...}\}[/tex]

Verify that 2(n+1) represents an even number where n is an odd number:

Put n=1 in 2(n+1) we get

2(1+1)=2(2)=4

Put n=3 in 2(n+1) we get

2(3+1)=2(4)=8

Put n=5 in 2(n+1) we get

From above results we get 2(n+1) represents an even number and is belongs to the set Y when n is an odd number.

Therefore Option E) is correct

If n is an odd number then 2(n+1) represents an even number.

Final answer:

To find the amount of cloth left over, subtract the amount used from the total amount. Jaquan had 9.5 yards of cloth left over, which can be expressed as the fraction 19/50.

Explanation:

To find the amount of cloth left over, we need to subtract the amount used from the total amount. Jaquan bought 25 yards of cloth, used 4.9 yards for a decoration, and used 10.6 yards to make costumes. To find the amount left over, we subtract the sum of 4.9 yards and 10.6 yards from 25 yards: 25 - 4.9 - 10.6 = 9.5 yards.

The amount of cloth left over can be expressed as a fraction by dividing the amount left over by the total amount. So, 9.5 yards can be written as the fraction 9.5/25, which can be simplified by dividing both the numerator and denominator by 0.5 to get 19/50. Therefore, the amount of cloth left over is 19/50.

Answer:

circumference is 59.6075

area is 282.743

Step-by-step explanation:

   To find the circumference and area of the circle, we need to first find the radius. This can be achieved using the distance formula.

   The distance formula goes as follows: for any two points on an coordinate plane, the distance can be calculated using a certain method. This method is the derived from the Pythagorean Theorem. Basically, you find the distance from right to left and square it, and then find the distance from up to down and square it. You add these two values together and then square root the whole thing. I know, its complicated.

   To apply this to your problem, we do 2-(-1) to find the distance from right to left (x-distance) and then we do 5-(-4) to find the distance from up to down (y-distance). 2-(-1)=3 and squaring that we get 9. 5-(-4)=9 and squaring that we get 81. Adding these two values together, we get 90 and square rooting it we get [tex]\sqrt{90}[/tex].

   The formula for circumference of a circle is 2Pi * radius and plugging in our values we get 2Pi * [tex]\sqrt{90}[/tex] which gives us approximately 59.6075.

   The formula for area of a circle is Pi * radius^2 and plugging in our values we get Pi * [tex]\sqrt{90}[/tex] ^2 which gives us approximately 282.743.

Given: Each boxes contain 8 jars of tomato sauce.

           Cook uses 2 jars from 1 of the boxes.

As we know total number of boxes is "x".

Number of jars in the pantry is [tex]8\ jars \times x\ boxes= 8x \ jars[/tex]

Answer: $9 per ticket

Step-by-step explanation: Unit price means the cost per unit. In this case, the cost per ticket.

Since we know that it costs $36 for 4 movie tickets, to find the cost for 1 movie ticket, we need to divide 4 into $36 or 4 into 36.

4 divides into 36 9 times. 9 x 4 is 36 and 36 - 36 is 0. So 4 divides into 36 9 times which means that each movie ticket costs $9.

So the unit price is $9 per ticket.
