List the prime factors of each of these numbers
a) 30
b) 24
c) 72
d) 100
Answer:
30= 2×3×5
24= 2cubed×3
72= 2cubed×3squared
100=2squared×5squared
Answer:
Step-by-step explanation:
a) 30 = 5 * 6 = 5 * 2 * 3
30 = 5 * 2 * 3
b) 24 = 4 * 6 = 2*2 * 2 * 3
24 = 2³ * 3
c) 72 = 8 * 9 = 2 *2 * 2 * 3 * 3
72 = 2³ * 3²
d) 100 = 10 * 10 = 2 * 5 * 2 * 5
100 = 2² * 5²

Determine whether the relation is a function. Explain why or why not.
{(2, 5), (3, –5), (4, 5), (5, –5)}
A.
Yes; no value in the domain corresponds to more than one value of the range.
B.
No; the domain value 5 corresponds to two range values, 2 and 3.
C.
Yes; multiple domain values correspond to the same range value.
Answer:
Ok so it is a function
A. Yes; no value in the domain corresponds to more than one value of the range.
Step-by-step explanation:
Since there is one value of
y
for every value of
x

4x + 3(4x + 7) = 4(7x + 3)
Answer: 1
Step-by-step explanation:4x + 3(4x + 7) = 4(7x + 3) + -3
Reorder the terms:
4x + 3(7 + 4x) = 4(7x + 3) + -3
4x + (7 * 3 + 4x * 3) = 4(7x + 3) + -3
4x + (21 + 12x) = 4(7x + 3) + -3
Reorder the terms:
21 + 4x + 12x = 4(7x + 3) + -3
Combine like terms: 4x + 12x = 16x
21 + 16x = 4(7x + 3) + -3
Reorder the terms:
21 + 16x = 4(3 + 7x) + -3
21 + 16x = (3 * 4 + 7x * 4) + -3
21 + 16x = (12 + 28x) + -3
Reorder the terms:
21 + 16x = 12 + -3 + 28x
Combine like terms: 12 + -3 = 9
21 + 16x = 9 + 28x
Solving
21 + 16x = 9 + 28x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-28x' to each side of the equation.
21 + 16x + -28x = 9 + 28x + -28x
Combine like terms: 16x + -28x = -12x
21 + -12x = 9 + 28x + -28x
Combine like terms: 28x + -28x = 0
21 + -12x = 9 + 0
21 + -12x = 9
Add '-21' to each side of the equation.
21 + -21 + -12x = 9 + -21
Combine like terms: 21 + -21 = 0
0 + -12x = 9 + -21
-12x = 9 + -21
Combine like terms: 9 + -21 = -12
-12x = -12
Divide each side by -12.
x = 1
Simplifying
x = 1

An equilateral triangle with side length 1 cm is shown in the diagram, work out the height of the triangle.
Give your answer rounded to 1 DP.
Answer:
0.9 cm
Step-by-step explanation:
c is the length of the side. a is the altitude. b is the base. a is the vertical bisector if the base, so the base is 0.5 cm.
c² = a² + b²
1² = a² + 0.5²
1² - 0.5² = a²
1 - 0.25 = a²
√0.75 = a
0.8660254 = a

Answer:
The quadratic equations and their solutions are;
9 ± √33 /4 = 2x² - 9x + 6.
4 ± √6 /2 = 2x² - 8x + 5.
9 ± √89 /4 = 2x² - 9x - 1.
4 ± √22 /2 = 2x² - 8x - 3.
Explanation:
Any quadratic equation of the form, ax² + bx + c = 0 can be solved using the formula x = -b ± √b² - 4ac / 2a. Here a, b, and c are the coefficients of the x², x, and the numeric term respectively.
We have to solve all of the five equations to be able to match the equations with their solutions.
2x² - 8x + 5, here a = 2, b = -8, c = 5. x = -b ± √b² - 4ac / 2a = -(-8) ± √(-8)² - 4(2)(5) / 2(2) = 8 ± √64 - 40/4. 24 can also be written as 4 × 6 and √4 = 2. So x = 8 ± 2√6 / 2×2= 4±√6/2.
2x² - 10x + 3, here a = 2, b = -10, c = 3. x =-b ± √b² - 4ac / 2a =-(-10) ± √(-10)² - 4(2)(3) / 2(4) = 10 ± √100 + 24/4. 124 can also be written as 4 × 31 and √4 = 2. So x = 10 ± 2√31 / 2×2 = 5 ± √31 /2.
2x² - 8x - 3, here a = 2, b = -8, c = -3. x = -b ± √b² - 4ac / 2a = -(-8) ± √(-8)² - 4(2)(-3) / 2(2) = 8 ± √64 + 24/4. 88 can also be written as 4 × 22 and √4 = 2. So x = 8 ± 2√22 / 2×2 = 4± √22/2.
2x² - 9x - 1, here a = 2, b = -9, c = -1. x = -b ± √b² - 4ac / 2a = -(-9) ± √(-9)² - 4(2)(-1) / 2(2) = 9 ± √81 + 8/4. x = 9 ± √89 / 4.
2x² - 9x + 6, here a = 2, b = -9, c = 6. x = -b ± √b² - 4ac / 2a = -(-9) ± √(-9)² - 4(2)(6) / 2(2) = 9 ± √81 - 48/4. x = 9 ± √33 / 4 .

(Brainliest for correct) You have decided to buy a Honda Accord LX, but you are concerned about the value of the car depreciating over time. You search the Internet and obtain the following information. The suggested retail price is $20,025. The depreciation per year is $1,385. What is the value of the car in dollars for 1 year of ownership, and how did you get that answer?
To find the value of the car after 1 year, subtract the amount it depreciates from the value of the car:
20,025 - 1,385 = 18,640
After 1 year the car is valued at $18,640
Answer:
$18640
Step-by-step explanation:
For year 1: Depreciated value is $1385.
We will minus that amount from the actual worth of car i.e. $20,025
So,
= $20,025 - $1385
= $18640

Micah pays 54$ for an item originally priced 60$. What percentage of the original price was his discount?
Answer: The percentage of the original price was his discount = 10%
Step-by-step explanation:
Given: original price = $60
Price after discount = $54
Discount = Price after discount - original price
= $ (60-54) = $6
The percentage of the original price was his discount = [tex]\dfrac{Discount}{Original\ price}\times100[/tex]
[tex]=\dfrac{6}{60}\times100\%\\\\=\dfrac{1}{10}\times100\%\\\\=10\%[/tex]
Hence, the percentage of the original price was his discount = 10%

Answer:
72
Step-by-step explanation:
As 3 lions & 3 tigers are to be arranged in a way that lions are not together. It can be done as per following arrangements
LTLTLT , or TLTLTL
Lions can be positioned in six ways, Tigers can also be positioned in 6 ways. There are two alternative positions.
Hence the arrangement can be done in 2 x 6 x 6 = 72 ways
The different ways should be 72.
