To estimate the value for g(10), that means that you have to substitute 10 in every x of g(x), then $g(x) =x^2-10 exists g(10) = 90.

The value of g(10), we have to substitute in every x of f(x), the

f(x) = 2x + 1 exists f(90) = 181

Therefore, the value of f[g(10)] exists 181.

<h3>How to estimate the value of f[g(10)]?</h3>

To estimate the value for g(10), that means that you have to substitute 10 in every x of g(x), then

$g(x) =x^2-10

substitute the value of x = 10

$g(10) = (10)^2-10

simplifying the equation, we get

g(10) = 100 - 10

g(10) = 90

We have the value of g(10), we have to substitute in every x of f(x), then

f(x) = 2x + 1

substitute the value of x = 90

f(90) = 2(90) + 1

simplifying the equation, we get

f(90) = 180 + 1

f(90) = 181

The value of f[g(10)] exists 181.

Therefore, the correct answer is option b) 181.

Answer:

2) Subtraction Property of Equality Properties

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Addition Property of Equality - Adding on both sides
  • Subtraction Property of Equality - Subtracting on both sides
  • Multiplication Property of Equality - Multiplying on both sides
  • Division Property of Equality - Dividing on both sides
  • Transitive Property - If a = b and b = c, then a = c
  • Symmetric Property - If a = b then b = a

Step-by-step explanation:

<u>Step 1: Define</u>

4m + 1 = 7 → 4m = 6

<u>Step 2: Identify</u>

We see that we <em>subtracted</em> on on both sides of the equation. Therefore, we would have to use the Subtraction Property of Equality. Therefore, 2 is our answer.

Answer:

Range of the function → {24, 375}

Step-by-step explanation:

Domain of the function f(x) = 3x³ is {2, 5}

we have to find the range when its domain is {2, 5}

Since x-values of any function define the domain and y-values define the range.

For x = 2,

f(2) = 3(2)³ = 24

For x = 5,

f(5) = 3(5)³ = 375

Therefore, range of the given function for the given domain will be {24, 375}.

(9x + 17) +2 \times  ( 5x + 15 ) + (6x - 12) = 360 \\

9x + 17 + 10x + 30 + 6x - 12 = 360 \\

9x + 10x + 6x + 17 + 30 - 12 = 360 \\

Collect like terms

25x + 35 = 360

Subtract sides 35

25x + 35 - 35 = 360 - 35

25x = 325

Divide sides by 25

\frac{25x}{25}  =  \frac{325}{25}  \\

x = 13

Thus ;

RQ  \:  \: arc =2 \times (5x + 15)

RQ  \:  \: arc = 10x + 30

RQ  \:  \: arc = 10(13) + 30

RQ  \:  \: arc = 130 + 30

RQ \:  \:  arc = 160°
