Answers

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:

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

Answers

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

Answers

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

Answers

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]

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

A triangle has an angle that measures 44.3 and another that measures 52.4" What is the measure of the third angle​

Answers

83.3, because all the angles have to add up to 180
180-44.3-52.4= 83.3

The measure of the third angle, if the other angles measure 44.3 and 52.4, is 83. 3 degrees.

How to determine the angle?

To determine the angle, we need to know the following;

The sum of the interior angles of a triangle is 180 degreesAlternating angles are equalCorresponding angles are equalSupplementary angles sum up to 180 degreesComplementary angles sum up to 90 degrees

Then, from the information given, we have that;

A triangle has an angle that measures 44.3 and another that measures 52.4"

Then, we get; x + 52.4 + 44.3 = 180
