Step-by-step explanation:
Determine for each X-value whether it is in the domain of f or not.
In domain
Not in domain
Answer:
Only -2 is in the domain because if you substitute -2 in for x, you would get a positive answer. The others would not work because you would get a negative number inside the square root, and you can't square root a negative number unless you are allowed to use imaginary numbers.

What is 73.613 rounded to the nearest whole number?
The given decimal rounded to the nearest whole number is 74.
The given decimal number is 73.613.
We need to round off the given decimal number to the nearest whole number.
How to round off the decimal number to the nearest whole number?There are two basic rules to round a decimal to the nearest whole number.
If the digit on the tenth place is less than 5, the rounding digit (the digit on one's place) remains the same and all the following digits including the decimal point are removed.If the digit on the tenth place is 5 or more than 5, we increase the rounding digit (the digit on one place) by 1, and all the following digits including the decimal point are removed.Now, rounding off 73.613 is checking the tenth digit which is 6.
Since 6 is more than 5, we will round up the number to 74.
Therefore, the given decimal rounded to the nearest whole number is 74.

Oni was timing her 100 meter sprints. Her first five sprints were 12.568 seconds, 11.426 seconds, 12.324 seconds, 11.981 seconds, and 12.601 seconds. Which two estimation techniques will give the same result for the total number of seconds for all five sprints?
Answer:
Rounding to the nearest tenth and rounding to the nearest one hundredth.
Step-by-step explanation:
round all up or down then line up and add
12.568= 13
11.426= 11
12.324= 12
11.981= 12
12.601= 13
add the totals then you see
60.83 sames as 61
Answer:
rounding to the nearest tenth and nearest hundredth
pleases help solve for x
Answer:
x = 31
Step-by-step explanation:
All of the angles in a triangle equal 180 degrees.
There is a 90 degree angle, and two unknown angles.
Your equation would be 90 + 2x - 2 + x + 5 = 180.
Combine like terms: 3x + 87 = 180.
Subtract 87: 3x = 93.
Divide 93 by 3 to cancel out x, and you get x = 31.

O A. (x-2)(x+3)(x-3)
O B. (x+3)(x + 6)(x - 1)
O c. 3(x - 1)(x+3)(x+2)
D. (x-3)(x + 3)(x - 2)
Answer:
C
Step-by-step explanation:
Given
3x³ + 12x² + 3x - 18
The sum of the coefficients = 3 + 12 + 3 - 18 = 0
Thus x = 1 is a root and (x - 1) is a factor
Divide 3x³ + 12x² + 3x - 18 by (x - 1) using Synthetic division
1 | 3 12 3 - 18
↓ 3 15 18
-----------------------------
3 15 18 0 ← remainder
Quotient = 3x² + 15x + 18 = 3(x² + 5x + 6)
Thus
3x³ + 12x² + 3x - 18 = 3(x - 1)(x² + 5x + 6) = 3(x - 1(x + 3)(x + 2) → C
4r+8+5=-15-3r ANSWER NUMBER FORM NO WORDS AT ALL
Answer:
r = -4
Step-by-step explanation:
Step 1: Write out equation
4r + 8 + 5 = -15 - 3r
Step 2: Combine like terms
4r + 13 = -15 - 3r
Step 3: Add 3r to both sides
7r + 13 = -15
Step 4: Subtract 13 on both sides
7r = -28
Step 5: Divide both sides by 7
r = -4
Answer: r=-4
Step-by-step explanation:
4r+13=-15-3r
7r+13=-15
7r= -28
r=-4

Choose the number line that correctly compares 24−−−√ and 4.256
Answer:
Option C
Step-by-step explanation:
See Attachment for number lines
Given
[tex]\sqrt{24}[/tex] and [tex]4.256[/tex]
Required
Compare both numbers
First, we need to determine [tex]\sqrt{24}[/tex]
[tex]Number = \sqrt{24}[/tex]
[tex]Number = 4.89897948557[/tex]
[tex]Number = 4.899[/tex] -- Approximated
Comparing 4.899 and 4.256; We have that
[tex]4.899 > 4.256[/tex]
Hence:
[tex]\sqrt{24} > 4.256[/tex]

Find the product of 6/9 and 3/8 . Express your answer in simplest form.A.6/24 B.1/6 C.18/72 D.1/4
Answer:
D.) 1/4
Step-by-step explanation:
6/9 x 3/8
6(3) /8(9)
= 18/72
18/18=1
72/18=4
= D.) 1/4
Answer:
D. 1/4
Step-by-step explanation:
First, we will multiply the numerator 6 × 3 = 18. Then, we'll multiply the denominators, 9 × 8 = 72. Then, divide 18 ÷ 18 = 1 and 72 ÷ 18 = 4. So there we go. the numerator is 1 and the denominator is 4. So the answer is 1/4 which is a proper fraction :) (mark this answer brainliest plz )
Joe is 14 years older than his cousin Tom.
Cousin Rob is 3 times as old as Tom. The sum of all
three of their ages is 64. Find each of their ages.
x = Tom's age
x + 14= Joe's age
3x = Rob's age
x + (x + 14) + 3x = 64
Let's combine like terms
5x + 14 = 64
Subtract 14 from both sides
5x = 50
Divide each side by 5
x = 10
Tom is 10 years old.
Joe's age = 10 + 14 = 24 years old
Rob's age = 3(10) = 30 years old

Formula for the area of a triangle:
A = 1/2(b · h) Where:
b = base, h = height
Substitute in the given values for the base and height:
A = 1/2(27 · 14)
A = 1/2(378)
A = 189 ft².
