Answer:
4(−3)2
Step-by-step explanation:
The common factor ) 42−24+36, 4(2−6+9)
Sum-product pattern ) 4(2−6+9) 4(2−3−3+9)
Common factor from the two pairs we did) 4(2−3−3+9) 4((−3)−3(−3))
Rewrite into factors ) 4((−3)−3(−3)) 4(−3)(−3)
Lastly, combine to a square.) 4(−3)(−3) 4(−3)2
I hope this helps you; g'day!
Given equation is 4x²-24x-36 = 0
⇛ 4(x²-6x-9) = 0
⇛ x²-6x-9 = 0
⇛ x²-2(x)(3) = 9
On adding 3² both sides then
⇛ x²-2(3)x)+3² = 9+9
⇛ (x-3)² = 18
⇛ (x-3) = ±√18
⇛ x-3 = ±√(2×9)
⇛ x-3 = ±3√2
⇛ x = 3±3√2
⇛ x = 3+3√2 or 3-3√2 Ans.

Find the equation of the graph given below. Notice that the sine function is used in the answer template, representing a sine function that is shifted and/or reflected.
Use the variable x in your equation, but be careful not use the multiplication x symbol.
y= __sin(___)+__
Answer:
y = 2sin(x/2 - pi/4) + 1
Step-by-step explanation:
The normal sine has a range of [-1, 1]. This one has a range of [-1, 3], so the amplitude is 2 times higher (4 vs 2).
After that, 2sin(x) has a range of [-2, 2], but this one has a range of [-1, 3], so we need to shift it upwards by 1.
We now know that the answer is 2sin(____)+1.
A normal sine has it's middle point while rising at x = 0, but this one has it at x = pi/2 - so we need to shift a sine to the right by pi/2.
Lastly, a sine has a cycle of length 2pi, but this one has a cycle of length 4pi. We can achieve that by dividing the argument 2.
We now know that the answer is 2sin(x/2 - pi/4) + 1. We can plot it to verify.
1) The initial volume of a balloon is 0.50 L. The initial temperature of the balloon is 150K. The volume in the balloon increased to 1.00 L.
What is the final temperature?
Use the below equation. Round to the nearest whole number and do not use units in your final answer.
T2=V2 x T1V1
2) A 2.5L container of an unknown gas has a pressure of 300kPa. The container is squeezed and has a final volume of 2.0L.
What is the final pressure of the container?
Use the below equation. Round to the nearest whole number and do not use units.
P2 =P1V1/V2
3) Charles’ law is
V1T1=V2T2
A closed container has an initial temperature of 300K. The container volume is changed until the final volume is 2L and the final temperature is 425K.
Calculate the initial volume using the equation from Charles' Law.
Use 2 decimal points in your answer and do not use units.

Answer:
[tex]log \left( \frac{a^2\,\,b^4}{c\,\,d^3} \right)[/tex]
Step-by-step explanation:
We use the properties of logarithms to write this as a single logarithmic expression. First the exponent property:
2 log(a) + 4 log(b) - log(c) - 3 log(d) =
= log(a^2) + log(b^4) - log(c) - log(d^3) =
and now the multiplication and division properties
= [tex]log \left( \frac{a^2\,\,b^4}{c\,\,d^3} \right)[/tex]

Help me please!!!!!!
Answer:
40
Step-by-step explanation:
1. multiply all terms by the same value to eliminate fraction denominators (n times 5/8 = n times 25/n)
2. cancel multiplied terms that are in the denominator (n times 5/8 = 25
3.re order terms so constants are on the left (5/8n =25)
4. combine multiplied terms into a single fraction (5n/8 = 25)
5. multiply all terms by the same value to eliminate fraction denominators (8 times 5n/8 = 8 times 25)
6. cancel multiplied terms that are in the denominator (5n=8 times 25)
7. multiply the numbers (5n = 8 times 25 5n= 200)

Lane wants a new video game priced at $55 and sales tax is 7%. What is the total cost of the video game after tax?
First, change the percentage to a decimal and find the sales tax amount.
55⋅0.07=$3.85
Now, add the sales tax amount to the original price.
55+3.85=$58.85
The final cost after tax is $58.85.
Answer:
The sales tax is determined by computing a percent of the purchase price. To find the sales tax multiply the purchase price by the sales tax rate. Remember to convert the sales tax rate from a percent to a decimal number. Once the sales tax is calculated, it is added to the purchase price.
