Answer:
x=36
Step-by-step explanation:
3x and 2x are both supplementary angles so adding them would get 180 since they are on opposite sides.
3x + 2x =180
5x = 180
(Divide by 5)
x=36

Step-by-step explanation:
x = 1 - i sqrt(2) ^ y = 10 + i sqrt(2)
x = 1 + i sqrt(2) ^ y = 10 - i sqrt(2)
Answer:
Step-by-step explanation:
y = 11 - x ----------(I)
y = 2x² - 4x + 6 -----------(II)
Substitute y = 11- x in (II)
11 - x = 2x² - 4x + 6
0 = 2x² - 4x + x + 6 - 11
0 = 2x² - 3x - 5
2x² - 3x - 5 = 0
Sum = -3
Product = -10
Factors = -5 , 2
2x² - 5x + 2x - 5 = 0
x(2x - 5) + (2x - 5) = 0
(2x -5 )(x +1)=0
2x - 5 = 0 ; x + 1 = 0
2x = 5 ; x = -1
x = 5/2
When x = -1 ; y = 11 - (-1) = 11 + 1 = 12
[tex]When x = \dfrac{5}{2} ; y = 11- \dfrac{5}{2}= \dfrac{22}{2}- \dfrac{5}{2}= \dfrac{17}{2}[/tex]
Solution: (-1 , 12) and (5/2 , 17/2)
Find dy/dx for (y^2/x) = 18 by implicit differentiation
Answers
9514 1404 393
Answer:
dy/dx = y/(2x)
Step-by-step explanation:
The product formula can be used, along with the power rule.
d(uv) = du·v +u·dv
__
d(y^2/x) = d(18)
2y·dy/x -y^2/x^2·dx = 0
2x·dy -y·dx = 0 . . . . . . . . multiply by x^2/y
dy/dx = y/(2x) . . . . . . . . add y·dx, divide by 2x·dx

A colony of E. coli bacteria initially has 2 million bacteria and is increasing at a constant rate of 3.5% every minute. Write a formula for the number of bacteria in the colony after tt minutes.
Answers
The formula for the number of bacteria in the colony after t minutes is [tex]y=2000000(1.035)^t[/tex]
An exponential growth is in the form:
y = abˣ
where y, x are variables, a is the initial value of y and b > 1
Let y represent the bacteria population after t minutes
Given that initially has 2 million bacteria, hence:
a = 2 million = 2000000
It increases at a rate of 3.5% every minute, hence:
b = 100% + 3.5% = 1.035
The equation is:
[tex]y=2000000(1.035)^t[/tex]
Therefore the formula for the number of bacteria in the colony after t minutes is [tex]y=2000000(1.035)^t[/tex]

Step-by-step explanation:
Plug the known values into the linear equation:
[tex]2x + ky = 8\\2(6) + k(4) = 8\\12 + 4k = 8\\[/tex]
Subtract 12 from both sides to isolate 4k:

An angle measures 4.6° less than the measure of its supplementary angle. What is the measure of each angle?
Answers
Answer:
The two angles are,87.7° and 92.3°Step-by-step explanation:
Question,To find an angle and it's supplementary angle.
Let,The supplementary angle be = x
So, the angle given is = x - 4.6
As we know,When two angles added gives 180°, then those angles are called supplementary angles.
Therefore solution,By the problem,
=> x + (x - 4.6) = 180
[On adding like terms x]=> 2x - 4.6 = 180
[Putting - 4.6 to other side of equal to which converts to 4.6]=> 2x = 180 + 4.6 = 184.6
[On dividing 2 on both sides][tex] = > \frac{2x}{2} = \frac{184.6}{2} [/tex]
[On Simplification]=> x = 92.3
Result:So, the supplementary angle is = 92.3° (Ans)(ii)
And, it's required angle is = 180° - 92.3° = 87.7° (Ans)(i)
Supplementary Angles :
If the sum of the measures of two angles is 180°, then the angles are called supplementary angles and each angle is called a supplement of the other.⠀
Given :
An angle measures 4.6° less than the measure of its supplementary angle.⠀
To Find :
The measure of each angle.⠀
Solution :
Let's assume the one of the supplementary angle as "x" and the other angle as (x + 4.6)° .Now,
According to the Question :
[tex]\begin{gathered}\\ \sf x + (x - 4.6) {}^{ \circ} = 180{}^{ \circ} \\ \\ \dashrightarrow \: \sf x + x - 4.6{}^{ \circ} = 180{}^{ \circ} \\ \\ \sf \: \dashrightarrow 2x - 4.6{}^{ \circ} = 180{}^{ \circ} \: \: \: \: \\ \\ \dashrightarrow \sf \: 2x = 180{}^{ \circ} + 4.6{}^{ \circ} \\ \\ \dashrightarrow \sf \: 2x = 184.6{}^{ \circ} \: \: \: \: \: \: \: \: \\ \\ \dashrightarrow \: \sf \: x = \frac{184.6 {}^{ \circ} }{2} \: \: \: \: \: \\ \\ \dashrightarrow \: \sf \: x = 92.3 {}^{ \circ} \: \: \: \: \: \\ \\\end{gathered}[/tex]
Therefore,
One angle = 92.3°Other angle = 180° – 92.3° = 87.7°⠀
Hence,
The measure of the two angles are 92.3° and 87.7° .If the graphs of the linear equations in a system are the same line, what does that mean about the possible solution or solutions of the system?

A chemist want to mix a 40% acid solution with a 70% acid solution to make 6 liters of a 50% acid solution. How much of each type of solution should the chemist use? Show your Work. I NEED HELP ASAP, PLZ HELP
Answers
Answer:
2 liters of 70%
4 liters of 40%
Step-by-step explanation:
Let
x = liters of 70%
Then the remaining amount is
6 - x = liters of 40%
---------------------------------
Mixing
(70% of x) + (40% of 6 -x) (to get) 50% of 6)
70(x) + 40(6-x) = 50(6)
Simplify
70x + (240 - 40x) = 300
Combine like terms
30x = 60
Divde both sides by 30
x = 2 liters of 70%
6 - x = 4 liters of 40%
