Answer:
<em><u>478</u></em>
Step-by-step explanation:
1*10+32(2+4+6)+76+2^3
First parenthesis
1*10+32(12)+76+2^3
Next exponents
1*10+32(12)+76+8
Next multiplication
10+384+76+8
Then add
394+84
Add
478
Therefore, your answer would be <u><em>478</em></u>
Answer: The correct option is second, i.e. ,"2 times the integral from 0 to 1 of the quantity x cubed minus 3 times x squared plus 2 times x, dx".
Explanation:
The given equation is,
It can be written as,
Find the zeros of the equation. Equation the function equal to 0.
So, the three zeros are 0, 1 and 2.
The graph of the equation is shown below.
From the given graph it is noticed that the enclosed by the curve and x- axis is lies between 0 to 2, but the area from 0 to 1 lies above the x-axis and area from 1 to 2 lies below the x-axis. So the function will be negative from 1 to 2.
The area enclosed by curve and x-axis is,
![A=\int_{0}^{1}f(x)dx+\int_{1}^{2}[-f(x)]dx](https://tex.z-dn.net/?f=A%3D%5Cint_%7B0%7D%5E%7B1%7Df%28x%29dx%2B%5Cint_%7B1%7D%5E%7B2%7D%5B-f%28x%29%5Ddx)
From the graph it is noticed that the area from 0 to 1 is symmetric or same as area from 1 to 2. So the total area is the twice of area from 0 to 1.
![A=2\int_{0}^{1}[x^3-3x^2+2x]dx](https://tex.z-dn.net/?f=A%3D2%5Cint_%7B0%7D%5E%7B1%7D%5Bx%5E3-3x%5E2%2B2x%5Ddx)
Therefore, The correct option is "2 times the integral from 0 to 1 of the quantity x cubed minus 3 times x squared plus 2 times x, dx".
Answer:
Step-by-step explanation:
6cos^2(x) + 7cos(x) +2 = 0
Call cos(x) = y to change this to something a little bit more familiar.
6y^2 + 7y + 2 =0
This equation is a quadratic. Solve it first. Then we'll go back to solving for cos(x)
This equation factors into 2 possible answers
(3y + 2)(2y + 1) = 0
3y + 2 = 0
3y = - 2
y = - 2/3
2y + 1 = 0
2y = - 1
y = - 1/2
Now let's start with
cos(x) = - 1/2
That means that x is in quadrant two or three.
cos-1(1/2) = 60 degrees.
Quad 2: x = 180 - 60 = 120
Quad 3: x = 180 + 60 = 240
Now cos(x) = - 2/3
cos-1(2/3) = 48.19
Quad 2: x = 180 - 48.19 = 131.81
Quad 3: x = 180 + 48.19 = 228.19
Answer:
Y=-1/2x ?
Step-by-step explanation:
There might be an y intercept. First find the slope. (Change in y over change in x) -2-1 over -1-5 then you get -3/-6. You can simplify an get -1/2. That forms an equation of y=-1/2x. That might be part of the answer. You still might need to find the y intercept, and I dont know how really. Hope this helps.
