There is only one value of c that satisfies the requirements.

=======================================================

Work Shown:

Let's compute the function value at the given endpoints of the interval.

[tex]f(x) = 4\sin(x)\\\\f(\pi) = 4\sin(\pi) = 0\\\\f(0) = 4\sin(0) = 0\\\\[/tex]

Which means,

[tex]f'(c) = \frac{f(b)-f(a)}{b-a}\\\\f'(c) = \frac{f(\pi)-f(0)}{\pi-0}\\\\f'(c) = \frac{0-0}{\pi}\\\\f'(c) = \frac{0}{\pi}\\\\f'(c) = 0\\\\[/tex]

We want to find all values of c such that the derivative is 0.

This can be rephrased into wanting to solve [tex]4\cos(x) = 0\\\\[/tex] since the derivative of sine is cosine

In other words, [tex]f(x) = 4\sin(x)\\\\[/tex] turns into [tex]f'(x) = 4\cos(x)\\\\[/tex]

Solving that equation leads to:

[tex]4\cos(x) = 0\\\\\cos(x) = 0\\\\x = \frac{\pi}{2}\\\\[/tex]

Use a reference table or the unit circle to determine this.

This is the value of c that satisfies f ' (c) = 0, such that [tex]0 < c < \pi[/tex]. No other value of c works.

If you graphed f(x) = 4sin(x), and only focused on the interval [0,pi], then you'll find that there's a horizontal tangent at the point (pi/2, 4). Note how the endpoints have the same y value so that's why the average rate of change over [0,pi] is 0.

Side note: this is an application of Rolle's Theorem

Answer:

The length of the third side of the triangle is 30.

Step-by-step explanation:

Here is the formula for the Pythagorean Theorem:

[tex]a^{2} + b^{2} = c^{2}[/tex]

The hypotenuse, based on the problem, is 50. Anyways, let's get back to calculating!

We need to multiply 40 times 40 and 50 times 50.

40 times 40, or 40 squared, equals to 1600.

50 times 50, or 50 squared, equals to 2500.

[tex]c^{2} - b^{2} = a^{2}[/tex]

Now, let's subtract. 2500 - 1600 = 900. We need to find the square root of 900--which is 30, because 30 times 30, or 30 squared, equals to 900.

Answer:

30

Step-by-step explanation:

c=√a^2+b^2

a=√c^2-b^2 = √50^2-40^2 = 30

Step-by-step explanation:

14 x 1.5 = 21

54 x 1.5 = 81

Answer:

m = 81

Step-by-step explanation:

divide by 54/14 from both sides.

you'll remain with 81/m

then divide with m/1 on both sides giving you m= 81

The cone and the sphere have the same volume.

___________________________________________

Volume of the cone

[tex] = \frac{1}{3}\pi {r}^{2} h[/tex]

[tex] = \frac{1}{3} \times \frac{22}{7} \times 2.4 \times 2.4 \times 8.3[/tex]

[tex] = 1 \times \frac{22}{7} \times 0.8 \times 2.4 \times 8.3[/tex]

[tex] = \frac{22}{7} \times 1.92 \times 8.3[/tex]

[tex] = \frac{22}{7} \times 15.93[/tex]

[tex] = 22 \times 2.27[/tex]

[tex] = 49.94[/tex]

[tex] = 50 {cm}^{3} (rounded)[/tex]

Also,

Volume of the sphere

= 50cm³

[tex] = \frac{4}{3} \pi {r}^{2} = 50[/tex]

[tex] \pi {r}^{2} = 50 \times \frac{3}{4} [/tex]

[tex]\pi {r}^{2} = 37.5[/tex]

The property of equality that justifies the statement where the statement is given as "If VR + TY = EN + TY, then VR = EN" is the subtraction property of equality

The statement is given as

If VR + TY = EN + TY, then VR=EN

In the above statement, we have the following equation

VR + TY = EN + TY

By applying the subtraction property of equality, we have the following equation

So, we have

VR + TY - TY = EN + TY - TY

Evaluate the  difference in the above equation

So, we have

VR = EN

Hence, the property of equality that justifies the statement where the statement is given as "If VR + TY = EN + TY, then VR = EN" is the subtraction property of equality

Answer:

He had 3 2/5 pies left when he got home.

Step-by-step explanation:

Hope this helped have an amazing day!

The fraction of candy cane pies that Dasher left is 8/5.

In such a fraction, the value that appears above the horizontal line is referred to as the numerator.

In another word, if we divide two numbers by each other then the upper word is called the numerator, and the lower word is called the denominator.

As per the given,

Number of candy cane pies that Dasher order = 4

Fraction he ate = 3/5

Left = 4 - ate

Left = 4 - (3/5)4

Left = 4(1 - 3/5)

Left = 4(2/5)

Left = 8/5

Hence "The fraction of candy cane pies that Dasher left is 8/5".

The sum of two or more vectors is called the Resultant.

The Resultant is the vector sum of two or more vectors. It is the result of adding two or more vectors together. If displacement vectors A, B, and C are added together, the result will be vector R.

Answer: It is $42.4

Step-by-step explanation: Multiply (0.20)(53), you get 10.6, now that's the price that is discounted, so subtract that from the total, to get $42.4. If you want to check your answer, do 42.4/53 and you would get 0.80, or 80%. That is what you should get since you have a 20% discount from 100% of a product.

Answer:

the sales price is $10.60

Step-by-step explanation:

to find 20% of 53, I multiplied 53 by 20 and 100 by a (i used the variable a to substitute for the answer we are going to get)

53 x 20 = 1060

100 x a = 100a

In order to get "a" we have to divide by 100 for each number.

1060 ÷ 100 = 10.6

100a ÷ 100 = a

in conclusion, a = 10.6, or $10.60 hope this helps :)

Step-by-step explanation:

Exterior angle theorem

50 + 70 = 120

Answer:

120

Step-by-step explanation:

the insides of a triangle add up to 180 degrees. You're given 70 and 50 degrees which add to 120 and that means the other angle is 60 degrees. Since you're trying to find an outside angle, you need to do subtract the 60 degrees we just found from 180 (because its a supplementary angle). 180-60 is 120 and thats the answer
