How to solve the indefinite integral

Mathematics
1 answer:
Minchanka [31]3 years ago
3 0

Answer:

\frac{1}{4}x^4-x^2+3x+c

Step-by-step explanation:

Use the the integration rules for powers of x: \int x^n dx = \frac{1}{(n+1)} x^{n+1} and the additive property of integrals:

f(x) = \int (x^3-2x+3)dx= \int x^3 dx-2\int x dx+\int 3 dx = \\=\frac{1}{4}x^4-x^2+3x+c

with c being an arbitrary constant.

The measures of angle 1and angle 2 are 25% and 45% of the sum of the angle measures of the triangle. Find the value of x.
Svetradugi [14.3K]
25+ 45= 70
70% of 180 is 126
170-126=54

Hope that’s right! I don’t know if that’s the appropriate way to do it, but that’s how I would do it.

what is the slope of a line parallel to the line whose equation is y=2/3x+7 fully simplify your answer
Olin [163]

Answer:

2/3

Step-by-step explanation:

When a line is parallel to another, it means that there are never going to be any solutions(they won't ever intersect each other.) To do so, the slope of the lines have to be the same. It doesn't matter what the y-intercept is.

So the slope of the second line is going to be the same as the first line: 2/3

If q(x)=7x^2-1 find q(-9)
liq [111]

For this, we are just going to plug in -9 for every x and then solve the equation:


q(x)=7x^{2} -1


q(-9)=7(-9)^{2} -1


q(-9)=7(81)-1


q(-9)=566


Now we know that q(-9) is equal to 566.

What is the y-intercept of function f?
Andru [333]

Answer:

y intercept = 5

Step-by-step explanation:

f(x)=5•(1/6)^x

The y intercept is when x =0

Let x =0

f(0)=5•(1/6)^0      

= 5* 1     = 5

The y intercept is 5

If the question is

f(x)=5•(1/6)x

although I have never seen the question written this way

The y intercept is when x =0

Let x =0

f(0)=5•(1/6)0      

= 5* 0     = 0

The y intercept is 0
