In circle K , diameter CD is drawn and point E is located on the circle such that CE=16 and DE=30 .What is the length of the radius of circle K?

Answers

Answer 1
Answer:

Answer:

The length of the radius of the circle K is 17\ units

Step-by-step explanation:

we know that

The triangle CDE is a right triangle with the 90 degree angle at point E

so

Applying the Pythagoras Theorem

Find the length of CD (diameter of the circle K)

CD^(2)=CE^(2)+DE^(2)

substitute the values

CD^(2)=16^(2)+30^(2)

CD^(2)=1,156

CD=34\ units

Find the radius

Remember that the radius is half the diameter

so

r=34/2=17\ units

Using the slope formula for the points (1, 5) and (2, -2), what would the denominator be?-2 - 5
-2 - 1
2 - 1
2 - 5

Answers

Answer:

2-1

Step-by-step explanation:

Answer:

1

Step-by-step explanation:

Moving from (1, 5) to (2, -2), x increases by 1 and y decreases by 7.  The slope of the line connecting these two points has the slope m = rise / run = -7 / 1, or just -7.

Alternatively, using the slope formula,

        5-[-2]           7

m = ------------ = -------- = (-7/1).  The denominator would be 1.

         1 - 2            -1

Which is bigger 4/5 or 9/10

Answers

Well 4/5 is 80% and 9/10 is 90%
9/10 is bigger. :)
To make it easier, we can change a fraction to have the same denominator so we can compare

Least Common Denominator
5 × 1 = 5                                            10 × 1 = 10
5 × 2 = 10

Least common denominator is 10

(4*2)/(5*2)  and (9)/(10)
(8)/(10)   and    (9)/(10)

(9)/(10)(8)/(10)

We see that more area is shaded in (9)/(10) than 

(9)/(10) is bigger

Name an event that would be measured in days

Answers

An event measured in days would be something long enough that to measure it in hours would be too big of a number.

Event measurement;

An event is measured in days if it occurs for a long course of a time such that counting it in a number of hours or minutes would be too long to calculate.

An event measured in days would be something long enough that to measure it in hours would be too big of a number.

For example, the Olympics could be measured in days because it takes place over the course of several weeks, so keeping track of Day 1, Day 2, etc. would make more sense than counting by hours.

The things like sporting events or freak storms are measured in days or weeks. Depends. For weather, it could be hurricanes, tornados, or even large fires(not quite weather, but could be).

Answer with explanation:

An event is measured in days if it occurs for a long course of a time such that counting it in number of hours or minutes would be too long to calculate in.

for example-

1) The happening of a Olympic games  or some other games that are held for a long course of a time could not be described in days.

2) Week:

a week has 7 days.
