Step-by-step explanation:

The equation of a circle is given below: (x - 0.5) + (y - 3.5)=16 what is it’s center and radius

Answers

Circle equation: (x - h) + (x - k) = r²

(h, k) = center

r = radius

The center (0.5, 3.5)

To find the radius, take the square root of 16.

√16 = 4

The radius is 4.

How To Find The nth Term Of A Geometric Sequence

Written by Hazmo  in Geometric Sequence

The nth term is one of the most important element of geometric sequence.

It’s usually used to find out specific values within the geometric sequences.

We calculate the nth term by first finding the common ratio ‘r’ by dividing any two consecutive terms of the sequence.

And then we substitute ‘a‘ with the first term of the sequence and ‘n’ with the term number to get the final answer of the nth term.

The general formula to find the nth term is:

an=a1r(n–1)

Understanding the nth term of a geometric sequence gets easier if we know the meaning of this term and variables used.

Therefore, let’s first find what the nth term is and then move on to the details of it’s evaluation with different examples.

The rule that is generated is 3, 9, 27, ........  an.

What is geometric progression ?

"Geometric Progression (GP) is a type of sequence where each succeeding term is produced by multiplying each preceding term by a fixed number, which is called a common ratio. This progression is also known as a geometric sequence of numbers that follow a pattern."

Given,

a3 = 27

and r = 3

Formula for nth term is given by

[tex]a_{n} = a_{1}r^{n-1}[/tex]

so, we have

[tex]27 = a1.3^2[/tex]

so a1 = 3

Hence, the series becomes 3, 9, 27, ........an

Answers

Answer: There are 22.2 pounds of water in the bag.

Step-by-step explanation:

Hi, to answer this question we simply have to multiply the total weight of the bag by the water percentage in decimal form (divided by 100).

Mathematically speaking:

30 x (74/100) = 30 x 0.74 =22.2 pounds

There are 22.2 pounds of water in the bag.

Select the grid that represents the ratio 3/5. Then find a percent equivalent to the given ratio. We

Answers

Answer:

60%

Step-by-step explanation:

I'm not sure about the grid (as you didn't attach any images), but I can help with the percentage part. To convert a fraction into a percentage, all you have to do is multiply the fraction by 100. When we do this, we get 3/5*100 = 60%.

Another way to think about it is to rewrite 3/5 so that it's denominaor is 100. We can mutiply the fraction by 20/20 which gives us 60/100. Note that this doesn't change the original fraction because 20/20 is equal to 1. Then, you simply take the numerator as the percentage. In this case, the numerator is 60, so the percentage will be 60%.

25. In the diagram, CT = 10.
What is the length of AB?

Answers

Answer:

The length of AB is 4.33012701892

Step-by-step explanation:

1. You find 10*sin(60 degrees), because sin(60 degrees) =  x/CT, and CT = 10. That means that sin(60 degrees) = x/10. You multiply by 10 on both sides, which would mean that x = 10sin(60 degrees) and that AT = 8.66025403784 because x is AT.

2. Then, because the relation between AT and AB and Angle T is sine, you use cosine to find x. If you do that, you find that the equation is sin(30 degrees) = x/8.66025403784. That means that 8.66025403784*sin(30 degrees) = x. If you calculate that, you find that x = 4.33012701892, and AB is x.

The measure of equal sides of an isosceles right triangle is 3√2.

Given that, the isosceles right triangle whose hypotenuse has a length of 6 inches. The lengths of the other 2 sides are a inches.

By using Pythagoras theorem, we get

6²=a²+a²

2a²=6²

2a²=36

a²=18

a=±√18

a=±3√2

Therefore, the measure of equal sides of an isosceles right triangle is 3√2.
