3. Answer:
x=3/2+1/2√21 or x=3/2+-1/2√21
Step-by-step explanation:
For this equation: a=1, b=-3, c=-3
1x2+−3x+−3=0
Step 1: Use quadratic formula with a=1, b=-3, c=-3.
x=−b±√b^2−4ac/2a
x=−(−3)±√(−3)^2−4(1)(−3)/2(1)
x=3±√21/2
x=3/2+1/2√21 or x=3/2+−1/2√21
Answer:
3: x= 3.7912874, x= 0.79128784
4: x= 0.62181997, x= -4.28848664
Step-by-step explanation:
It’s all solve for x what number actually makes the equation true.

Answer:
[tex]\sqrt{3}[/tex]
Step-by-step explanation:
See attachment 1. This is the formula to use.
There are two numbers, so n=2. Plugging them into the formula, you get
[tex]\sqrt[2]{6*\frac{1}{2}} \\[/tex]
Now, putting a 2 in front just means we're finding the square root, so I'll get rid of it. Then, just do the calculation.
[tex]\sqrt{6*\frac{1}{2}}=\sqrt{\frac{6}{2}}=\sqrt{3}[/tex]
Answer:
√3
Step-by-step explanation:
To find the Geometric mean, multiply the values given, then take the square root.
x² = ab
x= √ab
It's a "central tendency" we are calculating.
This is different from the arithmetical mean which uses addition and division to find that average.

Step-by-step explanation:
y = 2x
y = 7x-20
Step 1: plug in 2x for y
Step 2: subtract 7x on both sides
Step 3: divide by -5 on both sides
Step 4: plug in 4 into y = 2x
2x = 7x -20
-7x -7x
-5x = -20
-5 -5
x = 4
y = 2(4)
y = 8

A new car is purchased for $40,000 and over time its value depreciates by one half every 3 years. What is the value of the car 17 years after it was purchased, to the nearest hundred dollars?
Answers
Answer:
Value of the car after depreciation = $800.
Step-by-step explanation:
Formula to get the final value of the car after depreciation of the car price,
Final value = [tex]\text{Initial value}(1-\frac{r}{100})^{\frac{t}{n} }[/tex]
Here, t = Number of years after the purchase
n = Number of years for the depreciation of price by half
By substituting values in the formula,
Final value = [tex]40000(1-\frac{50}{100})^{\frac{17}{3}}[/tex]
= [tex]40000(0.5)^{\frac{17}{3}}[/tex]
= $787.451
≈ $800 [Nearest hundred dollars]
Therefore, after 17 years value of the new car will be $800.

What is mean by Fraction?A fraction is a part of whole number, and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called fraction.
It can be written as the form of p : q, which is equivalent to p / q.
We are Given that 0.41 repeating.
Consider x = 0.41, then multiply both sides of this equation by 100 to remove the decimal point:
100x = 41.41
Simplifying;
99x = 41
Dividing both sides by 99;
x = 41/99
