Answer:
Y' = -xsin(2x) + 2cos(2x)
Step-by-step explanation:
For this problem, we will need to use the product rule since you have two terms that contain the variable x.
The product rule is simply as follows:
The derivative of the function is the product of the first term times the derivative of the second term plus the derivative of the first term times the second term.
Note the derivative of 2x with respect to x, is 2.
Note the derivative of cos(2x) with respect to x is (-1/2) sin(2x).
With this in mind, let's find the derivative of our function with respect to x.
Y = 2xcos2x
Y = 2x * cos(2x)
Y' = 2x * (-1/2)sin(2x) + 2 * cos(2x)
Y' = (2x * -1 / 2) sin(2x) + 2 * cos(2x)
Y' = (-x)sin(2x) + 2cos(2x)
So the derivative of our function is Y' = -xsin(2x) + 2cos(2x) according to the application of the product rule.

The three incoming currents at a
node in an electrical circuit
measure 0.38 amps, 0.75 amps,
and 0.29 amps. Two of the three
outgoing currents measure 0.48
amps and 0.6 amps. Find the
measure of the third outgoing
Current
PLS HELP
Answer:
Measure of the third outgoing current will be 0.34 ampere.
Step-by-step explanation:
Kirchhoff's Current Law states that total current entering a circuit's junction is exactly equal to the total current leaving the same junction.
By this rule,
Sum of input three currents = Sum of three outgoing currents
0.38 + 0.75 + 0.29 = 0.48 + 0.6 + i
1.42 = 1.08 + i
i = 0.34
Therefore, measure of the third outgoing current will be 0.34 ampere.

Answer:
Option (C)
Step-by-step explanation:
x and y are two rational numbers.
Two inequalities which define these numbers are,
x + y < 5 ------(1)
3 < x < 5 -------(2)
In this question we will substitute the values of y given in the options in the inequality (1) to get the value of x. If the value of x satisfies the inequality (2), it will be the answer.
Option (A). y = [tex]\frac{8}{3}[/tex]
From inequality (1),
[tex]x+\frac{8}{3}<5[/tex]
[tex]x<5-\frac{8}{3}[/tex]
x < [tex]\frac{7}{3}[/tex]
x < 2.33
But 3 < x < 5, therefore, y = [tex]\frac{8}{3}[/tex] is not the answer.
Option (B). y = 2
x + 2 < 5
x < 3
But x is greater than 3. Therefore, Option (B) will not be the answer.
Option (C). y = 0
x + 0 < 5
x < 5
Inequality (2) states the same thing.
Therefore, Option (C) will be the answer.
Option (D). y = 3
x + 3 < 5
x < 5 - 3
x < 2
But x > 3, therefore, Option (D) will not be the answer.
Answer:
C is correct because if x is less than 5 and greater than 3 than is would most likely be 4 and 4 plus 0 equals 4 the problem says x plus y should be less than 5 and 4 plus 0 is less than 5
Step-by-step explanation:
Long answer short the answer is c

Combine like terms to create an equivalent expression. -(4)/(7)p+(-(2)/(7)p)+(1)/(7)
Answer:
-6/7p + 1/7
Step-by-step explanation:
Like Terms: terms that have the same variables and powers
In this equation the like terms are -4/7p and -2/7p
First solve that, which will be -6/7p + 1/7
You have to leave the 1/7 alone because there aren't any more numbers with no variables.
Answer:
Step-by-step explanation:
You can only combine terms that are the same, which means you can only combine the fractions with p attached. A + and - make a -. The second fraction changes to negative or subtraction which ever way you want to say it. -4 - 2 = -6 and the bottom number always stays the same and you keep the letter attached. You can not combine 1/7 because it does not have a p attached. You would leave it the same. [tex]\frac{-6}{7}p +\frac{1}{7}[/tex]

Jason with 120 and is going 10 pounds each month Gerardo weighs 150 pounds and is having 4 pounds each month . Write an equation that shows how many months , m , it will take for Jason weigh the same as Gerardo
Answer:
5 months
Step-by-step explanation:
Jason's original weight = 120 pounds
Let the no. of months be m
If he gains 10 pounds in each moth , then his weight in m months will be = 10m
His total weight will be= 120+10m -----(1)
Gerardo's original weight = 150 pounds
If he gains 4 pounds in each month , then his weight in m months will me =4m
His total weight will be = 150+4m-----(2)
Equating (1) ans(2)
120+10m=150+4m
=>10m-4m=150-120
=>6m=30
=>m=[tex]\frac{30}{6}[/tex]
=>m=5
It will take 5 months for Jason to weigh the same as Gerardo

A pizza restaurant offers 6 toppings to choose from for their pizzas, and no toppings is considered a plain cheese pizza. How many different pizza topping combinations are possible if the maximum number of allowed toppings is 3 and toppings can't repeat
Answer: 120
Step-by-step explanation:
Given : Total toppings = 6
Number of toppings needs to be selected = 3
Also if repetition of toppings is not allowed , then the number of combinations are possible = 6 x 5 x 4 [First we choose 1 out of 6 , then 1 out of remaining 5 and then 1 out of 4,then multiplying the choices for 3 toppings]
= 120
Hence, the number of different pizza topping combinations are possible if the maximum number of allowed toppings is 3 is 120 .

Please let me know if you have any question
The graph below represents the amount of change Jaxon would receive, y, if he bought a item with a cost of x. Which equation represents the graph?
1. y = 10 – x
2. y = x – 10
3. y = –x – 10
4. y = 10 + x
PLS help!!!
Answer:
1. y = 10 - x
Step-by-step explanation:
Because he starts off with 10 dollars, and x is the amount he spends on an item, y is showing the change that he would get from paying with a 10 dollar bill, so it's what's left over from that 10 dollars.

Given that cos x° =Sin (3x +10)
find tan X°
Answer:
the answer is tan 20 =0.364
Step-by-step explanation:
we can write sin(3x+10)= cos{90-(3x+10)}
now
cosx= cos{90-(3x+10)}
eliminating cos from both sides we get
x=90-3x-10
4x=80
x=20
tan 20=0.364
it can be 40 also

If m and n are off then is mn even?
Answer:
No, mn is not even if m and n are odd.
If m and n are odd, then mn is odd as well.
==================================================
Proof:
If m is odd, then it is in the form m = 2p+1, where p is some integer.
So if p = 0, then m = 1. If p = 1, then m = 3, and so on.
Similarly, if n is odd then n = 2q+1 for some integer q.
Multiply out m and n using the distribution rule
m*n = (2p+1)*(2q+1)
m*n = 2p(2q+1) + 1(2q+1)
m*n = 4pq+2p+2q+1
m*n = 2( 2pq+p+q) + 1
m*n = 2r + 1
note how I replaced the "2pq+p+q" portion with r. So I let r = 2pq+p+q, which is an integer.
The result 2r+1 is some other odd number as it fits the form 2*(integer)+1
Therefore, multiplying any two odd numbers will result in some other odd number.
------------------------
Examples:
3*5 = 157*9 = 6311*15 = 1659*3 = 27So there is no way to have m*n be even if both m and n are odd.
The general rules are as follows
odd * odd = oddeven * odd = eveneven * even = evenThe proof of the other two cases would follow a similar line of reasoning as shown above.

Three consecutive numbers are such that when they are taken in increasing order and multiplied by 2,3and 4 respectively, they add up to 74. Find these numbers.
Answer:
7 , 8 , 9
Step-by-step explanation:
Assume three consecutive number are,
x , (x+1) , (x+2)
Multiplied by 2 ,3 and 4 respectively
2x , 3(x + 1) , 4(x + 2)
Sum of all = 74
So,
2x + 3(x + 1) + 4(x + 2) = 74
2x + 3x + 3 + 4x + 8 = 74
9x + 11 = 74
9x = 63
x = 7
So,
x , (x+1) , (x+2)
7 , (7+1) , (7+2)
7 , 8 , 9

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

(1 + 4i) (1 + 4i)
FOIL - first -- outer -- inner -- last
F -- 1 x 1 = 1
O -- 1 x 4i = 4i
I -- 4i x 1 = 4i
L -- 4i x 4i = 16i²
combine terms
1 + 4i + 4i + 16i²
simplify
1 + 8i + 16i²
(i² = -1)

1 + 8i + (16)(-1)
1 + 8i - 16
-15 + 8i
given the indicated terms of an arithmetic sequence a3=1, a33=22 find the first term
Answer:
The first term is a = 0.4.
Step-by-step explanation:
We are given the indicated terms of an arithmetic sequence; [tex]a_3[/tex] = 1, [tex]a_3_3[/tex] = 22.
As we know that the nth term of the A.P. is given by;
[tex]a_n=a+(n-1)d[/tex]
where, a = first term and d = common difference
Now, the third term of AP is given as 1, this means;
[tex]a_3=a+(3-1)d[/tex]
[tex]a+2d=1[/tex]
a = 1 - 2d --------------- [equation 1}
Also, the 33rd term of AP is given as 22, this means;
[tex]a_3_3=a+(33-1)d[/tex]
[tex]a+32d=22[/tex]
[tex]1-2d+32d=22[/tex] {using equation 1}
[tex]30d=21[/tex]
[tex]d=\frac{21}{30}[/tex]
d = 0.7
Putting the value of d in equation 1 we get;
[tex]a=1-(2 \times 0.7)[/tex]
a = 1 - 1.4 = -0.4
Hence, the first term of an AP is -0.4.
