Find the radius of a circle if a 48-meter chord is 7 meters from the center. *
Airida [17]

Answer:

The radius of the circle is 25m

Step-by-step explanation:

Here, we are to calculate the radius of the circle.

The distance from the circle center, the half the length of the chord and the radius forms a right triangle with the radius being the hypotenuse.

We can then use Pythagoras’s theorem to approximate the value of the radius

Mathematically, the Pythagorean theorem establishes that the square of the hypotenuse = the sum of the squares of the other two sides

r^2 = 7^2 + 24^2

r^2 = 49 + 576

r^2 = 625

r = √(625)

r = 25m

F the base is 4, what is the value if the exponent is 2? What if the exponent is -2?
nasty-shy [4]

Answer:

Step-by-step explanation:

value of 4, and you want to square it or exponent 2

so 4^2 = 4x4

=16

What is ^-2

It does the same operation however because to is negative it really means putting 4 in the denominator so 2 becomes positive. Inverse of the exponent 2

1/4^2 is the same as 4^-2

which will both give 1/16

The area of a rectangle is 27 ft2 , and the length of the rectangle is 3 ft less than double the width. find the dimensions of t
user100 [1]
Let w be the width;and 2w-3 be the length. Then:
w(2w-3)=27
2w²-3w-27=0
(2w-9)(w+3)=0
w=9/2 or -3
The width is 9/2 ft, the length is 6

You purchase boxes of cereal until you obtain one with the collector's toy you want. If, on average, you get the toy you want in
Zina [86]

Answer:

The probability of getting the toy you want in any given cereal box is p=0.056.

Step-by-step explanation:

On average, you get the toy you want in every 18th cereal box.

This value corresponds to the mean of a geometric distribution, where it is expected that you get 17 "failures" before the first "success".

The mean of the geometic distribution, whose value is 18, can be written as:

E(X)=\dfrac{1}{p}=18

where p is the probability of "success": getting the collector's toy you want.

Then, p has a value of 1/18≈0.056.
