Answer:
The length of the chord is 30cm
Step-by-step explanation:
Given
[tex]r = 17cm[/tex]
[tex]d = 8cm[/tex]
Required
Calculate the chord length (L)
This is calculated as:
[tex]L = 2 * \sqrt{(r^2 -d^2)[/tex]
So:
[tex]L = 2 * \sqrt{(17^2 - 8^2)[/tex]
[tex]L = 2 * \sqrt{225[/tex]
[tex]L = 2 * 15[/tex]
[tex]L = 30cm[/tex]

A rectangle has an area of 2x2 - 19x +45 ft? What are the dimensions of the rectangle? (hint: factor)
The dimensions of the rectangle will be (2x - 9)(x - 5).
What is a quadratic equation?A quadratic equation is a polynomial with a degree of 2 or the maximum power of the variable is 2 in quadratic equations. It has two solutions as its maximum power is 2.
Given that the area of the rectangle is represented by a quadratic equation 2x² - 19x +45.
The dimensions of the rectangle will be the factors of the quadratic equation.
2x² - 19x + 45
2x² - 10x -9x + 45= 0
2x( x - 5 )-9(x - 5)= 0
( 2x - 9 ) ( x - 5 ) = 0
Therefore, the dimensions of the rectangle will be (2x - 9)(x - 5).

✨✨Answer number 7please ✨✨
Answer: A
Step-by-step explanation: This is a rotation. An easy way to tell the difference between a rotation and a reflection is that the order of the points will not change in a rotation. For this problem, pre-image ABCD is still in the order of ABCD when mapped to the image. (You can still follow along the points in that order). When something is reflected, the points swap orders and you would not be able to follow the points in order.
Now that we know this is a rotation, Notice A’ B’ C’ and D’ are all left of the pre-image. This means the mapped image moves counter clockwise.

Step-by-step explanation:
ABCD and JKLM are similar. To find the x, first find the ratio for all of the sides.
AD and JM are similar --> 2.4 / 3 = 0.8
BC and KL are similar --> 4 / 5 = 0.8
DC and ML are similar --> 2.4 / 3 = 0.8

[need to right more because my question is too short stuff in brackets is irrelevant]
On Tuesday, Marissa was $45 short of her fundraising goal. The next day, she was $5 over her goal write an equation to show how much she raised in one day.
Answer: Hello daema, let's let x be the goal and c be the collection per day.
x - 45 + c = x + 5 is the answer so now let's talk about how we did that.
So she wants to get to x which is the goal. But right now she has 45 less than what her goal is. So that would look like this x - 45 now she has to get c or the collection per day to get to her goal. So now it looks like this x - 45 + c. Now that c has to be at least x which is her goal, it now will look like this x - 45 + c = x. But we're not done, the question said that now she 5$ over her goal, or x. So we have to add the + 5 onto the end so now it looks like this x - 45 + c = x + 5. To solve the equation "if you have to" it would be x = 50$ per day.
