the length of a chord of a circle is 24 cm long and is 5 cm away from the center of the circle what is the radius of the circle​
iogann1982 [59]

Answer:A chord with length 24 cm at 5 cm from the center gives a radius of 13 cm, using a half-length of 12 cm and the distance of 5 cm in Pythagoras’s theorem to find the radius.

Using the same radius and Pythagoras's theorem again, a chord 10 cm from the circle with radius 13 cm has a half-length of sqrt(69), or a full length of double that, so 2*sqrt(69).

Make a scatter plot of the data. Then find an equation of the quadratic function that models the data.
nika2105 [10]

The equation of the quadratic function that models the data is y = x^2 + 3x + 4

<h3>How to determine the scatter plot?</h3>

A quadratic function is represented as:

y = ax^2  +bx + c

Next, we enter the data values on the table to a graphing calculator.

From the graphing calculator, we have:

a = 1, b = 3 and c = 4

Substitute these values in y = ax^2  +bx + c

So, we have

y  = x^2 + 3x + 4

Hence, the equation of the quadratic function that models the data is y = x^2 + 3x + 4 and the scatter plot is (a)

The Salami and More Deli sells a 5-foot submarine sandwich for parties. It weighs 8 pounds. Assuming that the weight per foot is
laiz [17]

Answer:

7.5 feet long

Step-by-step explanation:

if I had one, 5 foot sandwich, I would have 8 pounds. if I had 2.5 more foot of sandwich I would have 4 more pounds ( because 2.5 feet is half of 5 feet which means we would have to divide 8 pounds by 2). which means I have 8 pounds and 4 pounds, which equals 12 pounds. I also have 5 feet and 2.5 feet of sandwich which is equal to 7.5 feet. since it's asking the length of a 12 pound sandwich, your answer is 7.5 feet long.

A person can do a job in 6 days. Another can do the same job in 4 days. If they work together, how long do they need to finish t
stepan [7]

Answer:

5 days

Step-by-step explanation:

This would have to do with average. So if one does it in 6 days and the other does it in 4 days, you would do the number between them. So 5 is between 4 and 6.

The more complicated way of thinking of it is like this...

add 6 and 4           6+4     that  would  =   10

Because we added two numbers, we have to divide by two.

10/2      which equals 5.

If it was numbers closer together like. 6 and 7 the middle numbeR would be 6.5 for example.

I hope this helped!!
