AP Calc BC help!
Can someone explain how to do these problems? I care more about the explanation than the actual answer! My course never taught me how to do these kinds of problems.
Thank you!!
Answer:
Question 1) 72
Question 2) 40
Question 3) Both C and D.
Question 4) Both A and C.
Step-by-step explanation:
Question 1)
We are given that:
[tex]\displaystyle \int_1^5f(x)\, dx=8\text{ and we want to find} \int_1^5xf'(x)\, dx[/tex]
We will use integration by parts, given by:
[tex]\displaystyle \int_a^b u\, dv=uv-\int_a^b v\, du[/tex]
We will let:
[tex]u=x\Rightarrow du=dx\text{ and } dv=f'(x)\, dx \Rightarrow v=f(x)[/tex]
Therefore:
[tex]\displaystyle \int_1^5xf'(x)\, dx=xf(x)\Big|_1^5-\int_1^5f(x)\, dx[/tex]
Substitute:
[tex]\displaystyle \int_1^5xf'(x)\, dx=(5(f(5))-(1(f(1))-(8)[/tex]
Evaluate:
[tex]\displaystyle \int_1^5xf'(x)\, dx=75-(-5)-8=72[/tex]
Question 2)
Similarly, we will let:
[tex]\displaystyle u=x\Rightarrow du=dx\text{ and } dv=f'(x)\, dx \text{ so } v=f(x)[/tex]
Hence:
[tex]\displaystyle \int_0^3 xf'(x)\, dx=xf(x)\Big|_0^3-\int_0^3f(x)\, dx[/tex]
Evaluate:
[tex]\displaystyle \int_0^3 xf'(x)\, dx=(3f(3))-(0(f(0))-(2)[/tex]
Thus:
[tex]\displaystyle \int_0^3 xf'(x)\, dx=3(14)-2=40[/tex]
Question 3)
We are given:
[tex]\displaystyle g(x)=\int_4^xf(x)\, dx[/tex]
By the Fundamental Theorem of Calculus:
[tex]g'(x)=f(x)>0[/tex]
The derivative of g is always positive. So, the values of g are always increasing.
The tables that reflect this are C and D.
And there are, as I understand it, no way to determine their exact values. Both C and D are correct.
Question 4)
Similarly, we are given:
[tex]\displaystyle g(x)=\int_{-2}^xf(x)\, dx[/tex]
By the FTC:
[tex]g'(x)=f(x)<0[/tex]
So, g should be decreasing for all x.
The tables that reflect this are A and C.
So, both A and C are correct.

Step-by-step explanation:
just try matgs is a tough de partoeIn comparing the two written forms of a sequence, which is easier to find a50, the explicit form or the recursive form?
Answer:
Explicit
Step-by-step explanation:
Given
[tex]Term: a_{50[/tex]
Required
Explicit or Recursive; which is easier
The explicit form is easier.
Take for instance, the explicit form of the sequence is:
[tex]a_n = 2n + 1[/tex]
And the recursive form is:
[tex]a_n = a_{n-1} + 2[/tex]
To find [tex]a_{50}[/tex] in [tex]a_n = 2n + 1[/tex]
You simply substitute 50 for n and then solve for [tex]a_n[/tex]
Which gives:
[tex]a_{50} = 2*50 + 1 = 101[/tex]
The case is different in: [tex]a_n = a_{n-1} + 2[/tex]
First, you substitute 50 for n
[tex]a_{50} = a_{50-1} + 2[/tex]
[tex]a_{50} = a_{49} + 2[/tex]
Next, you need to calculate a49.
This action continues until you get to a1
Then you evaluate the corresponding expressions from a1 to a49 before you get a50.
Hence, the explicit form is easier.
the square of a number is 16 do you know the number
Answer:
4
Step-by-step explanation:
4 squared, which is the same thing as 4 times 4, is 16.
[tex]4^2=16[/tex] or [tex]4 * 4 = 16[/tex]
you can check your answer by finding the square root of 16.
[tex]\sqrt{16}=4[/tex]

Answer:
The answer is below
Step-by-step explanation:
Select the correct answer from each drop-down menu. Simplify the given polynomial and use it to complete the statement.
(-5x² - 2x + 4) + (8x² - x - 1) + (x + 2)(x - 5)
.The polynomial simplifies to an expression that is a____
A.quadratic
B.liner
C.constany
A.trinomial
B.binomial
C.monomial
with a degree of____
A.1
B.2
C.0
Solution:
A polynomial is an expression involving operations of addition, subtraction, multiplication, exponents which consists of variables and their coefficient. A trinomial is a polynomial consisting of three terms, while a binomial consist of two terms and a monomial consist of one term.
The degree of a polynomial is the highest degree of any of the terms of the polynomial. If it has a degree of 0 it is a constant, a degree of 1 it is linear while for a degree of 2 it is quadratic.
(-5x² - 2x + 4) + (8x² - x - 1) + (x + 2)(x - 5)
= (-5x² - 2x + 4) + (8x² - x - 1) + (x² -5x + 2x - 10)
= (-5x² - 2x + 4) + (8x² - x - 1) + (x² - 3x - 10)
= (-5x² + 8x² + x² - 2x - x - 3x + 4 - 1 - 10)
= 4x² - 6x - 7
Therefore:
.The polynomial simplifies to an expression that is a quadratic trinomial of degree 2.
A movie theater is offering a special summer pass. Passholders pay $8 per movie for the first 5 movies and watch additional movies for free, up to a maximum of 15 movies. The function C gives the total cost, in dollars, for a passholder to watch n movies.
Is function C a piecewise function? Explain your reasoning.
probably it's 8 or 4. and as $8 is the initial fee, that sounds like the starting value. :-)
the line equation you need is the slope intercept form y = mx + b where m = gradient and b = y intercept.
in this case, y = 4x + 8 where x = number of movies seen, and y = total cost in $
for this line m = 4 and b = 8. hence, indeed, the y intercept is 8

circumference and area of radius 42
Answer:
Area = 5542.488 unit^2
Circumference= 263.9 units
Step-by-step explanation:=
Given data
Radius= 42 units
Circumference= 2πr
C= 2*3.142*42
C=263.9 units
Area= πr^2
A= 3.142* 42^2
A= 3.142* 1764
A= 5542.488 unit^2

Can someone solve these for me I have no idea what to do and it has to be turns in within an hour
Answer:
Step-by-step explanation:
Subtract second equation from first equation to eliminate x
2x+6y-2x+10y=17-9
16y=8
y=1/2, use either original equation to solve for x
2x+6y=17 becomes
2x+6(1/2)=17
2x+3=17
2x=14
x=7 so the solution is the point (7, 1/2)
We can multiply the first by -2 and add it to second equation to eliminate x.
-2(3x-4y)+6x+3y=-2(-10)-42
-6x+8y+6x+3y=20-42
11y=-22
y=-2 using 3x-4y=-10 becomes
3x-4(-2)=-10
3x+8=-10
3x=-18
x=-6 so the solution is the point (-6,-2)
So you should be able to see how to solve the other two.
Answer:
Question 1: x = 7, y = [tex]\frac{1}{2}[/tex]
Question 2: x = -6, y = -2
Question 3: x = -1, y = 9
Question 4: There is no solution.

to make this easier make sure all fractions have the same denominator 6/3x2/2=12/6 since they now have the same denominator add 12/6+-1/6=11/6
adding a negative(6/3+-1/6) is the same as subtracting a positive(6/3-1/6)

Answer:
3 + 2n
Step-by-step explanation:
2 + 1 = 3.
2n cannot be added into this because it has a letter in front of it. Therefore, it stays on its own.
2n + 3
1 and 3 are like terms, and because there are no more variables, the 2n will stay alone :)

In a recent survey of 655 working americans ages 25-34, the average weekly amount spent on lunch was $43.29 with standard deviation $2.75. The weekly amounts are approximately bell-shaped
Answer:
99.7%
Step-by-step explanation:
Given that:
sample size (n) = 655
sample mean ([tex]\overline x[/tex]) = 43.29
Standard deviation [tex]\sigma[/tex] = 2.75
Let's assume we are to estimate the percentage between $33.72 and $51.54
Then;
The test statistics at 33.72 is :
[tex]Z = \dfrac{X - \mu}{\sigma}[/tex]
[tex]Z = \dfrac{33.72 -43.29}{2.75}[/tex]
[tex]Z = -3.48[/tex]
Z at 51.54
[tex]Z = \dfrac{X - \mu}{\sigma}[/tex]
[tex]Z = \dfrac{51.54 -43.29}{2.75}[/tex]
[tex]Z = 3.00[/tex]
Using the empirical standard rule, the percentage will be 99.7%
