The coordinates (x,y) of a shape after dilation by a factor of k centered at the origin is given by :-

[tex](x,y)\rightarrow(kx,ky)[/tex]

Given : Rectangle HIJK has vertices H(-3, 2), I(4, 2), J(4, -3), and K(-3, -3).

The coordinates of the image of I after a dilation by a factor of 1.5 centered at the origin will be :_

[tex]I(4,2)\rightarrow I' (1.5\times4, 1.5\times2)=I'(6,3)[/tex]

Hence, the coordinates of the image of I after a dilation by a factor of 1.5 centered at the origin =I’(6, 3)

Mean = 110

Sample size = 45

Standard deviation = 6

Z score for 90% is 1.645 ( from Z-table).

Lower Limit = Mean - Z(SD/√Sample size))

Lower limit = 110 - 1.645(6/√45)

Lower limit = 108.5

Upper Limit = Mean + Z(SD/√Sample size))

Lower limit = 110 +1.645(6/√45)

Lower limit = 111.5

The interval is (108.5, 111.5)

Answer:

Step-by-step explanation:

v= 1/3 bh

multiply by : 3

3v = bh

dividid by b : h = 3v/b

To solve for h in the equation v = (1/3)bh, you need to isolate h on one side. Multiply both sides by 3 to eliminate the fraction, then divide both sides by b to solve for h.

To solve the equation v = (1/3)bh for h, we need to isolate h on one side of the equation.

First, we can multiply both sides of the equation by 3 to get rid of the fraction: 3v = bh.

Next, to solve for h, we divide both sides of the equation by b. This gives us the final answer: h = 3v / b.

Answer:

Step-by-step explanation:

Using a system of equations, it is found that:

If Ben is x years old, the expression 3x + 5 gives the sum of Ben’s and Teresa’s ages. If Ben is 7 years old, the sum of Ben’s and Teresa’s ages is 26 years.

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the variables are given by:

Teresa’s age is 5 years more than twice Ben’s age, hence:

y = 2x + 5

The sum of their ages is:

x + y = x + 2x + 5 = 3x + 5.

Ben is 7 years old, hence the sum is given by:

3(7) + 5 = 26.

Then:

If Ben is x years old, the expression 3x + 5 gives the sum of Ben’s and Teresa’s ages. If Ben is 7 years old, the sum of Ben’s and Teresa’s ages is 26 years.

More can be learned about a system of equations at https://brainly.com/question/24342899

The sum of Ben's and Teresa's ages is represented by the expression 3x + 5, and when Ben is 7 years old, their total age is 26 years.

The expression to represent the sum of Ben's age and Teresa's age, given that Ben is x years old and Teresa's age is 5 years more than twice Ben's age, is 2x + 5 + x. This can also be simplified to 3x + 5.

When Ben is 7 years old, we plug in the value 7 for x in the simplified expression to calculate the sum of their ages: 3(7) + 5, which equals 21 + 5.

Therefore, the sum of Ben's and Teresa's ages when Ben is 7 years old is 26 years.

Answer: [tex]6[/tex]

Step-by-step explanation:

Given the following expression:

[tex]8a-1+0.5b[/tex]

You need to substitute the given values of "a" and "b" into the expression. Notice that these values are:

[tex]a=\frac{1}{4}\\\\b=10[/tex]

Then;

 [tex]8a-1+0.5b=8(\frac{1}{4})-1+0.5(10)[/tex]

Now you must solve the multiplications:

[tex]=\frac{8}{4}-1+5=2-1+5[/tex]

The final step is to add the numbers. Therefore, you get the following answer:

[tex]=6[/tex]

The value of the expression 8a - 1 + 0.5b evaluates to 6 for a = 1/4 and b= 10.

To evaluate the expression 8a - 1 + 0.5b when a = 1/4 and b = 10, you can substitute these values into the expression and then perform the calculations:

1. Substitute the value of a:

  8 * (1/4) - 1 + 0.5 * 10

2. Simplify each term:

  - First term: 8 * (1/4) = 2

  - Second term: -1

  - Third term: 0.5 * 10 = 5

3. Add the simplified terms:

  2 - 1 + 5 = 1 + 5 = 6

So, when a = 1/4 and b = 10, the expression 8a - 1 + 0.5b evaluates to 6.

Answer:

The mid-point (p + q , q + p) of AB is the same distance from the x-axis and the y-axis

Step-by-step explanation:

* Lets explain how to solve the problem

- Any point will be equidistant from the x-axis and the y-axis must have

 equal coordinates

- Ex: point (4 , 4) is the same distance from the x-axis and the y-axis

 because the distance from the x-axis to the point is 4 (y-coordinate)

 and the distance from the y-axis and the point is 4 (x-coordinate)

- If (x , y) is the mid-point of a segment its endpoints are

 [tex](x_{1},y_{1})[/tex]  and [tex](x_{2},y_{2})[/tex], then

 [tex]x=\frac{x_{1}+x_{2}}{2}[/tex] and [tex]y=\frac{y_{1}+y_{2}}{2}[/tex]

* Lets solve the problem

∵ Point A has coordinates (p , q)

∵ Point B has coordinates (p + 2q , q + 2p)

- The mid-point of AB is (x , y)

∵ [tex]x=\frac{p+p+2q}{2}[/tex]

∴ [tex]x=\frac{2p+2q}{2}[/tex]

- Take 2 as a common factor from the terms of the numerator

∴ [tex]x=\frac{2(p+q)}{2}[/tex]

- Divide up and down by 2

∴ x = p + q

∵ [tex]y=\frac{q+q+2p}{2}[/tex]

∴ [tex]y=\frac{2q+2p}{2}[/tex]

- Take 2 as a common factor from the terms of the numerator

∴ [tex]y=\frac{2(q+p)}{2}[/tex]

- Divide up and down by 2

∴ y = q + p

∴ The mid point of AB is (p + q , q + p)

- p + q is the same with q + p

∵ The x-coordinate of the mid point of AB is p + q

∵ The y-coordinate of the mid point of AB is q + p

∵ p + q = q + p

∴ The coordinates of the mid-point of AB are equal

- According the explanation above

∴ The mid-point (p + q , q + p) of AB is the same distance from the

   x-axis and the y-axis

Step-by-step explanation:

According to the question Kendra have 120 stickers

10 stickers fill a page

So, number of pages that can be filled be 120 stickers = [tex] \frac{120}{10} = 12[/tex]

Therefore, she can fill 12 pages by 120 stickers.

The total number of pages Kendra can fill with a total number of 120 stickers is 12 pages.

Kendra has 120 stickers, and 10 stickers fill a page.

To calculate how many pages she can fill, divide the total number of stickers by the stickers per page:

120 stickers ÷ 10 stickers/page = 12 pages.

The inequality c + 1/c ≥ 2 for c > 0 is proven by using the AM-GM inequality method. By applying this method, we find that the arithmetic mean of the variables is indeed greater or equal to 2, hence confirming the inequality.

To solve the inequality c + 1/c ≥ 2 for c > 0, we can use the AM-GM (Arithmetic Mean - Geometric Mean) inequality method.

According to AM-GM inequality, for any positive numbers a, b, the arithmetic mean is always greater or equal to the geometric mean. In notation: (a + b)/2 ≥ sqrt(a * b). Applying this to our problem where a = c and b = 1/c, we get (c + 1/c) / 2 ≥ sqrt(c * 1/c). This simplifies to c + 1/c ≥ 2*1 = 2, therefore our inequality is confirmed.

The inequality c + 1/c ≥ 2 for c > 0 is proven using the AM-GM inequality by setting a = c and b = 1/c, showing that their arithmetic mean is always greater or equal to their geometric mean.

To prove the inequality c + 1/c ≥ 2 for c > 0, we can apply the AM-GM inequality which stands for Arithmetic Mean - Geometric Mean inequality. The AM-GM inequality states that for any non-negative real numbers a and b, the arithmetic mean is always greater than or equal to the geometric mean. That is, (a + b)/2 ≥ √(ab).

In our case, we can let a = c and b = 1/c. Then, according to the AM-GM inequality, we get:

When we multiply both sides of the inequality by 2, we get:

This completes the proof for the inequality c + 1/c ≥ 2 when c > 0.
