Answer:15/22
Step-by-step explanation:
Determine the equation for a circle in standard form with a radius of 18, and center (18,-18).
Answer:
(x-18)²+(y+18)²=18².
Step-by-step explanation:
1) the formula is: (x-x₀)²+(y-y₀)²=r², where (x₀;y₀) - coordinates of the centre, r - the length of the radius;
2) according to the formula above:
(x-18)²+(y+18)²=18².
The radius of the sphere is 10 units. What is the approximate volume of the sphere? Use 3.14 round to nearest whole cubic unit
Answer:
2,355 cubic units
Step-by-step explanation:
We will see that the volume of the sphere is 2,355 cubic units.
How to get the volume of a sphere?
We know that for a sphere of radius R, the volume is given by:
Here we know that:
R = 10 units
pi = 3.14
Replacing that in the volume equation we get:
So the volume of the sphere is 2,355 cubic units.

Using the recurrence relation s(1) = 2 and s(2)=3, s(k) =s(k-1)+2s(k-2)+6, find the fourth term
Recurrence functions are used to preedict the subsequent value in a sequence. The fourth term of the sequence based on the recurrence relation is 25
How to find the recurrence relation of a function?Given the recurrence relations according to the question
s(1) = 2 and
s(2)=3
s(k) =s(k-1)+2s(k-2)+6
If s(1) = 2, hence;
s(3) =s(3-1)+2s(3-2)+6
s(3) = s2 + 2s1 + 6
s(3) = 3 + 2(2) + 6
s(3) = 13
Determine the fourth term:
s(4) =s(4-1)+2s(4-2)+6
s(4) = s3 + 2s2 + 6
s(4) = 13 + 2(3) + 6
s(4) = 25
Hence the fourth term of the sequence based on the recurrence relation is 25

A number line has end points marked at 5 tenths and 6 tenths with 9 tick marks between. Point A is labeled on the third mark after 5 tenths.
Select all of the following that give the value of point A.

53
100
B.

C.

D.

E.

Answer:
[tex]\sf 0.53\quad and \quad \dfrac{53}{100}[/tex]
Step-by-step explanation:
Convert the end points to decimals:
[tex]\textsf{5 tenths}=\dfrac{5}{10}=5 \div 10=0.5[/tex]
[tex]\textsf{6 tenths}=\dfrac{6}{10}=6\div 10=0.6[/tex]
If the number line has 9 tick marks between the endpoints, there will be 10 equal spaces (see attachment), so the tick marks denote hundredths.
The difference between 0.6 and 0.5 = 0.1
Divide this by 10: 0.1 ÷ 10 = 0.01
Therefore, each tick mark on the number line denotes hundredths and is 0.01 greater than the previous tick mark.
If Point A is labeled on the third mark after 5 tenths then:
A = 0.5 + 0.01 + 0.01 + 0.01 = 0.53
0.53 as a fraction:
[tex]\implies 0.53 = \dfrac{0.53}{1}=\dfrac{0.53 \times 100}{1 \times 100}=\dfrac{53}{100}[/tex]
Therefore, point A is:
[tex]\sf 0.53\quad and \quad \dfrac{53}{100}[/tex]

ALEKS Knowlege Check:
Evaluate the expressions.
Answer:
1, -1
Step-by-step explanation:
(-2/3)⁰
Anything that is raised to the power of 0 automatically becomes the value 1. Knowing this, apply the exponent.
(-2/3)⁰ = 1
-(7)⁰
Now using what we know, apply the exponent to the 7.
-(7)⁰ = -1
Notice that the negative is NOT inside the parenthesis and therefore does NOT get affected by the power.

Answer:
In scientific notation:
The first number in the mathematical equation is called the "coefficient." The coefficient must be greater than or equal to one and less than 10. For example to create the scientific notation for the number 256, the coefficient would be 2.56.
The second number in the equation is a power of 10, written as 10 with an exponent, like 102 which stands for 10 x 10.
Combining these two numbers would create this scientific notation equation for 256 - 2.56 x 102.
A negative exponent shows the decimal is moved that many places to the left and a positive exponent shows the decimal is moved that many places to the right.
Scientific Notation Examples
Here are examples of scientific notation:
1 = 100
10 = 1 x 10¹
100 = 1 x 10²
1000 = 1 x 10³
10000 = 1 x 104
100000 = 1 x 105
42,000,000 = 4.2 x 107
676,000,000,000 = 6.76 x 1011
0.1 = 1 x 10-1
0.01 = 1 x 10-2
0.001 = 1 x 10-3
0.0001 = 1 x 10-4
0.00001 = 1 x 10-5
0.00000078 = 7.8 x 10-7
0.000000000000000 = 3.56 x 10-13
