therefore that is your answer

Step-by-step explanation:

x²+y²−8x−2y=48

the radius => √[(8/2)² + (2/2)² +48] =

√(16+1+48) =√65

the center => (8/2, 2/2)

=> (4, 1)

Simplifying Rs = st + -1Rt Solving sR = st + -1tR Solving for variable 's'. Move all terms containing s to the left, all other terms to the right. Add '-1st' to each side of the equation. sR + -1st = st + -1st + -1tR Combine like terms: st + -1st = 0 sR + -1st = 0 + -1tR sR + -1st = -1tR Combine like terms: -1tR + tR = 0 sR + -1st + tR = 0

s = − Rt / R − t

Answer:

136 Degrees

Step-by-step explanation

Set up as (3x+11) + (5x-9) = 90

then solve for x using algebra.

you can do this because angle NSO and RSQ are eqaul once you know x you will be able to solve all the other angles and subtract from 360 (the total angle) to find NSR.

Steps:

3x+11+5x-9 = 90

8x+2=90

x= 11

Solve 3(11)+11 = 44

add known angles:

44+90+90 = 224

360-224 = 136 degrees

We use concepts like complimentary angles and vertical angle theroem.

3[tex]\sqrt{11}[/tex]

Step-by-step explanation:

[tex]\sqrt{99}[/tex] = 3[tex]\sqrt{11}[/tex]

The area of a rectangle is 99 square units. Its width measures 9 units. Find the length of its diagonal. Round to the nearest tenth of a unit.

A.)

From the table ;

We could deduce, that the value of y increases as x increases : this could mean a direct variation :

y α x

y = kx

k = constant of proportionality

k = y/x

Missing value of x in the table could be inferred to be 4

Find k., when x = 4 and y = 32

k = 32/4

k = 8

Hence :

Values of y :

For x = 1

y = 8 × 1 = 8

For x = 2

y = 8 × 2 = 16

For x = 3

y = 8 × 3 = 24

For x = 5

y = 8 × 5 = 40

The table :

x __ 0 __ 1 __ 2 __ 3 __ 4 ___ 5

y __ 0 __ 8 _ 16 __24 _ 32 __ 40

B.)

The relationship between amount earned and number of hours is proportional as values obey the proportionality relationship shown in A.

C.)

The point which represents the constant of proportionality should have a y value of 8 :

Hence, the point is 1.

D.)

The y/x ratio :

Point 0 :

y/x = 0/0 = 0

Point 1 :

y/x = 8/1 = 8

Point 2 :

y/x = 16 /2 = 8

Point 3 :

y/x = 24/3 = 8

Point 4 :

y/x = 32 / 4 = 8

Point 5 :

y/x = 40 / 5 = 8

Answer:

RS = 20

ST = 40

Step-by-step explanation:

R____S____T

RS + ST = RT

3x - 16 + 4x - 8 = 60

3x + 4x - 16 - 8 = 60

7x - 24 = 60

    +24    +24

--------------------------------

7x = 84

/7     /7

---------------------------------

x = 12

Let's use what we got for x to find the length of ST and RS

ST = 4x - 8

= 4(12) - 8

= 48 - 8

ST = 40

RS = 3x - 16

= 3(12) - 16

= 36 - 16

RS = 20

so, RS = 20, ST = 40, and RT = 60

Answer:

RS = 20 and ST = 40

Step-by-step explanation:

x = 12

use this to find RS and ST by plugging in to their equations.

Answer:

were it goes straight thro the 0

Step-by-step explanation:

A composite function is the combination of two or more functions to create another function. The value of (f o g)(1) is 126

Given that:

[tex]f(x) = 2x^2 + 4x + 15[/tex]

[tex]g(x) = 2x^2 + 4x[/tex]

[tex](f\ o\ g)(x)[/tex] is calculated as:

[tex](f\ o\ g)(x) = f(x) \times g(x)[/tex]

So, we have:

[tex](f\ o\ g)(x) = (2x^2 + 4x + 15) \times (2x^2 + 4x)[/tex]

Substitute 1 for x

[tex](f\ o\ g)(1) = (2 \times 1^2 + 4 \times 1 + 15) \times (2 \times 1^2 + 4 \times 1)[/tex]

[tex](f\ o\ g)(1) = (21) \times (6)[/tex]

[tex](f\ o\ g)(1) = 126[/tex]

Hence, the value of (f o g)(1) is 126

Answer:

Ans; 58.80528

Step-by-step explanation:

Ans; ( 8.73) ( 42.1)(0.16) = (873) ( 421) (16) × 10^-⁵ = ( 367533) (16) × 10^-⁵ = 5880528 × 10^-⁵ = 58.80528

I hope I helped you^_^

The value of 0.16 x 42.1 x 8.73 after multiplying is 58.80528.

Given,

(0.16)(42.1)(8.73)

We need to multiply the decimal numbers.

When we multiply decimal numbers the decimal point should be placed after the number of counts from the right side.

The number of counts is the sum of the counts of numbers before the decimal point of each decimal number from the right side.

Example:

1.23 x 134.5

Here,

In 1.23 there are two numbers before the decimal point.

In 134.5 there is one number before the decimal point.

So the count = 2 + 1 = 3

So,

There should be three numbers after the decimal point in 1.23. x 134.5.

1.23. x 134.5 = 165.435

Find 0.16 x 42.1 x 8.73 by multiplying.

We see that,

There are two numbers after the decimal point in 0.16

There are one numbers after the decimal point in 42.1

There are two numbers after the decimal point in 8.73

So,

2 + 1 + 2 = 5 numbers

There should be 5 numbers after the decimal point in 0.16 x 42.1 x 8.73

Now,

0.16 x 42.1 x 8.73 = 58.80528.

Thus the value of 0.16 x 42.1 x 8.73 is 58.80528.
