The reason the "+ C" is not needed in the antiderivative when evaluating a definite integral is; The C's cancel each other out as desired.
How to represent Integrals?
Let us say we want to estimate the definite integral;
I = [tex]\int\limits^a_b {f'(x)} \, dx[/tex]
Now, for any C, f(x) + C is an antiderivative of f′(x).
From fundamental theorem of Calculus, we can say that;
[tex]I = \int\limits^a_b {f'(x)} \, dx = \phi(a) - \phi(b)[/tex]
where Ф(x) is any antiderivative of f'(x). Thus, Ф(x) = f(x) + C would not work because the C's will cancel each other.

Mollie wants to measure the capacity of the kitchen sink.
She has a 1 L container and a 10 mL container. Which should she use and why?
A.
10 mL container; the capacity of the sink is close to 10 mL.
B.
10 mL container; the capacity of the sink is less than 1 L so the 1 L container would not give an accurate measurement.
C.
1 L container; the capacity of the sink is at least 1 L.
D.
Either container; or the 10 mL container can measure the capacity as quickly as the 1 L container.
Answer:
1L container as the capacity of the sink is obviously at least 1L and most probably much more than 1L

What is the derivative of the function f(x)= 4cos2x + logx + x?
Answer:
[tex]f'(x)=-8\sin2x+\frac{1}{x} +1[/tex]
Step-by-step explanation:
I assume by [tex]\log(x)[/tex], the base is [tex]e[/tex], so let [tex]\log_e(x)=\ln(x)[/tex]:
[tex]\displaystyle f(x)=4\cos2x+\ln x+x\\\\f'(x)=\frac{d}{dx}(4\cos2x+\ln x + x)\\\\f'(x)=\frac{d}{dx}(4\cos2x)+\frac{d}{dx}(\ln x)+\frac{d}{dx}(x)\\\\f'(x)=-8\sin2x+\frac{1}{x}+1[/tex]
Remember that by the chain rule, to find the derivative of [tex]4\cos2x[/tex], you must find the derivative of the inside, which is [tex]\displaystyle \frac{d}{dx}(2x)=2[/tex], and multiply it by the outside derivative. Recall that [tex]\displaystyle \frac{d}{dx}\cos(x)=-\sin(x)[/tex], so replace [tex]-\sin(x)[/tex] with [tex]-4\sin(2x)[/tex], and multiply by 2 to get [tex]-8\sin(2x)[/tex] as your derivative.
Also remember that [tex]\displaystyle \frac{d}{dx}\ln(x)=\frac{1}{x}[/tex], one of the more basic derivatives.
The derivative of the function f(x)= 4cos2x + logx + x is f'(x)=-8sin2x+1/x+1.
What is Differential equation?A differential equation is an equation that contains one or more functions with its derivatives.
The given function is four times of cos2x plus logx plus x.
f(x)= 4cos2x + logx + x
We need to find the derivative of it f'(x)
d/dxf(x)=d/dx(4cos2x)+d/dx(logx)+d/dx(x)
f'(x)=4d/dx(cos2x)+d/dx(logx)+d/dx(x)
We know that
d/dx(cosx)=-sinx
d/dx(logx)=1/x
d/dx(x)=1
Apply in above equation
f'(x)=4d/dx(cos2x)+d/dx(logx)+d/dx(x)
f'(x)=4.2(-sin2x)+1/x+1
f'(x)=-8sin2x+1/x+1
Hence the derivative of function f(x)= 4cos2x + logx + x is f'(x)=-8sin2x+1/x+1.

What is the answer to this
Ryder used front-end estimation to estimate the product of (–24.98)(–1.29). What was his estimate?
–32
–20
20
32
Answer:
(d) 32
Step-by-step explanation:
An estimate is a value that is intended to approximate the result of a detailed calculation. Often, the target is an estimate that is within about 10% of the actual value. A "rough order of magnitude" (ROM) estimate is intended to be within about a factor of 3 of the actual value.
__
An estimate is generally made by using a reduced number of significant figures in the calculations. Often, the numbers used will be rounded to 1 or 2 significant figures. The math is often accomplished mentally, so methods of mental arithmetic are often used to simplify the calculations.
rounded valuesWe are asked for an estimate of the product (-24.98)(-1.29). We notice there are an even number of minus signs, so the result will be positive. The values are (25)(1.3) when rounded to 2 significant figures.
Along with the rounded values, it is often useful to make note of the direction and magnitude of the errors due to rounding. Here, we have rounded both numbers up. The number 25 is high by 0.02, and the number 1.3 is also high by 0.01. These can be used to estimate the error in the estimated value.
the productThe desired product can be computed several different ways. Either or both of the numbers 25 and 1.3 can be represented in a fashion that facilitates the (mental) arithmetic. Here are three (3) methods that could be used.
(25)(1.3) = 25(1 +0.3) = 25 +7.5 = 32.5 (a little high, so we can choose to round down to 32)(25)(1.3) = (100/4)(1.3) = 130/4 = 65/2 ≈ 64/2 = 32 (again, rounding down because we know 32.5 is too high)(25)(1.3) = 2.5(13) = 2(13) +13/2 = 26 +6.5 = 32.5 ≈ 32Ryder's estimate was 32.
_____
Additional comment
The actual product is ...
(25 -0.02)(1.3 -0.01) = (25)(1.3) -0.02(1.3) -0.01(25) +(0.02)(0.01).
As a first approximation of the error in the product 32.5, we can sum the middle two terms:
-0.02(1.3) and -0.01(25) = -0.026-0.25 = -0.276.
Then the first refinement of the estimate will give us ...
32.500 -0.276 = 32.224
The actual value is obtained by adding the final error term:
32.224 +0.0002 = 32.2242 . . . . the actual product with estimate errors resolved.

Find the volume of the prism.
9km 8km 6km
The correct answer is option B which is the volume of the prism is 216 km³.
What is the volume of the prism?A prism is a three-dimensional solid with a triangular base called a triangular prism. The volume of the triangular prism is equal to the product of the area of the base and the height of the prism.
The volume of the prism will be calculated by using the formula below:-
V = Area of the base x Height
Since the base is a right-angle triangle so we will calculate the area of the right-angle triangle.
V = Area of the triangle x Height
V = ( 1/2 ) x 8 x 6 x ( 9 )
V = 216 km²
Therefore the correct answer is option B which is the volume of the prism is 216 km³.

Which of the following rules is the composition of a dilation of scale factor 2, then a translation of three units to the right? a) (2x+3,y) b) (2x+6, 2y) c) (2x +3, 2y) d) (2x+6, y)
Answer:
The answer is C: (2x +3, 2y)
Step-by-step explanation:
When applying the dilation of a scale factor of 2, you have to apply it to both the x and y coordinate, which means you are multiplying the coordinates by 2.
Let's assume the coordinates you start with are (x, y). Apply the dilation of 2.
(x, y) -----> (2x, 2y)
Now you are moving the figure right. When moving right, this only effects the x coordinate since the x axis moves left and right. Moving right indicates you will add the number of units translated to the x coordinate.
Translation 2 units right:
(2x, 2y) -----> (2x +3, 2y)

Answer: A
Step-by-step explanation:
[tex]$$Given $m \angle A=9 x-7, \quad m \angle B=7 x-9, m \angle C=28-2 x$ \\For the triangle $m \angle A+m \angle B+m \angle c=180$$$\begin{aligned}&\Rightarrow(9 x-7)+(7 x-9)+(28-2 x)=180 \\&\Rightarrow 9 x+7 x-2 x-7-9+28=180 \\&\Rightarrow 14 x=180-28+16 \\&\Rightarrow 14 x=168 \\&\Rightarrow \quad x=12\end{aligned}[/tex]
[tex]$$Therefore,\\&m \angle A=9 x-7=9 \times 12-7=101^{\circ}\\&m \angle B=7 x-9=7 \times 12-9=75^{\circ} \\&m \angle C=28-2 x=28-2 \times 12=28-24=4^{\circ}\\[/tex]

Speed = Distance / Time
Speed = 481 / 13 = 37 miles per hour.
Now the time to cover a distance of 814 miles will be calculated as:-
Time = Distance / Speed

Answer:

Step-by-step explanation:
The equation of a circle is; (x+7)²+(y-6)² = 50
What is circle?A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.
The points on the circle are L(-2, 11) and centre is N(-7, 6)
Find the radius,
D = √(-7+2)²+(6-11))²
D = √25+25
D = √50
We know that, the equation of a circle is given by,
( x − a )² + ( y − b )² = r² , where ( a , b ) represents the centre of the circle,
Here, centre is N(-7, 6)
Therefore, the equation of a circle is;
(x+7)²+(y-6)² = 50
Hence, the required equation is (x+7)²+(y-6)² = 50
