Answer 2

The surface area of the right circular cylindrical container that has a radius of 7 cm and a height of 16 cm in terms of π is 322π.  This is obtained by using the formula for surface area of cylinder.

What is the surface area ?

Surface area of cylinder is, S = 2πrh+2πr², where S is the surface area, r is the radius and h is the height of the cylinder.

Given that r =7 cm, h =16 cm,

S = 2πrh+2πr²

  = 2π(7)(16)+2π(7)²

  = 224π+98π

  = 322π

Hence the surface area of the right circular cylindrical container that has a radius of 7 cm and a height of 16 cm in terms of π is 322π.

This happens twice in the first rotation on our unit circle.

It happens in the first quadrant and in the second quadrant. Third and fourth quadrants are negative for sine.

So we are looking for when the y-coordinate on the unit circle is sqrt(3)/2.

This is at pi/3 and 2pi/3.

So we can get all the solutions by adding +2pi*k to both of those.  This gives us a full rotation about the circle any number of k times. k is an integer.

So the solutions are

x=pi/3 + 2pi*k

To solve the problem we must know the concept of the Center angle theorem. The measure of the center angle ∠AOC  is 160°.

What is the central angle theorem?

According to the central angle theorem, if an arc of a circle makes an angle with any point on the circumference of that circle then the measure of that angle is half the angle made by that arc at the center of the circle.

Given to us

∠ABC = 80°

As we already know the angle made by Arc AC at point B, therefore, the center angle made by ARC AC at the center will be twice of it. Therefore,

∠AOC = 2∠ABC

∠AOC = 2(80°)

∠AOC = 160°

Angles 2 and 4 are vertical angles, which means they have the same angle measure because they are opposite of each other. So angles 2 and 4 are both 114 so that makes 228. All of the angles have to make 360, so 360 - 228 = 132. Then, 132/2 because there are two angles. That makes 66. And angles 1 and 3 are also vertical angles so they are also the same

Step-by-step explanation:

The given equation describes a parabolic curve with zeros at x=-1 and x=7. The line of symmetry of the curve is halfway between the zeros, at ...

  x = (-1 +7)/2 = 6/2 = 3

The maximum of the curve is on the line of symmetry. The ball will reach its maximum height 3 seconds after being thrown.

_____

Additional comment
The maximum height will be 16 meters.

Final answer:

The ball will reach its maximum height 3 seconds after being thrown.

Explanation:

To find the time when the ball reaches its maximum height, we need to determine the vertex of the quadratic equation representing the ball's height. The equation h(x)=-(x+1)(x-7) can be rewritten in vertex form as h(x)=-x^2+6x-7. The x-coordinate of the vertex can be found using the formula x = -b/2a, where a, b, and c are the coefficients of the quadratic equation.

In this case, a = -1 and b = 6. Plugging these values into the formula, we get x = -6/-2 = 3. Therefore, the ball reaches its maximum height 3 seconds after being thrown.

if m + 1 is an an even integer which one of the following must be an odd integer ?
A : m - 1
B : 2m - 2
C : 2m + 1
D : 2m + 2

Answers

To find which expression must be an odd integer when m + 1 is even, we analyze each option using substitution. The only option that results in an odd integer is 2m + 1.

If m + 1 is an even integer, then m must be an odd integer. Let's analyze each option to see which one of them must be an odd integer:

(A) m - 1: Since m is odd, subtracting 1 from an odd number will result in an even number. Therefore, (A) m - 1 is not an odd integer.(B) 2m - 2: If we substitute an odd integer for m, we get (2 * odd) - 2, which simplifies to an even number. Thus, (B) 2m - 2 is not an odd integer.(C) 2m + 1: Substituting an odd integer for m gives (2 * odd) + 1, which simplifies to an odd number. Therefore, (C) 2m + 1 is an odd integer.(D) 2m + 2: If we substitute an odd integer for m, we have (2 * odd) + 2, which simplifies to an even number. Hence, (D) 2m + 2 is not an odd integer.

Therefore, the answer is (C) 2m + 1 as it is the only option that must be an odd integer.

Final answer:

Option C, which is 2m + 1, must be an odd integer if m + 1 is an even integer because adding 1 to any even integer results in an odd integer.

Explanation:

Given that m + 1 is an even integer, we can determine which of the other expressions would therefore be an odd integer. We know that any even integer can be written in the form 2k, where k is an integer, because even integers are multiples of 2. Similarly, odd integers can be written as 2k + 1, where k is also an integer.

Given the options:

A: m - 1, if m + 1 is even, then m is odd, and subtracting 1 from an odd number results in an even number, so this option is not correct.B: 2m - 2, this is clearly even because it is a multiple of 2 regardless of the value of m, so this option is not correct.C: 2m + 1, if m is odd (since m + 1 is even), this will result in an odd number, so this option is correct.D: 2m + 2, like option B, this is also clearly even, so this option is not correct.

Therefore, the answer is C: 2m + 1.

Answer:

Step-by-step explanation:

Recall the following Pythagorean Identity:

Let's solve the x equation for cos(t) and the y equation for sin(t).

After the solve we will plug into our above identity.

x=5cos(t)

Divide both sides by 5:

(x/5)=cos(t)

y=5sin(t)

Divide both sides by 5:

(y/5)=sin(t)

Now we are ready to plug into the identity:

[tex]\sin^2(t)+\cos^2(t)=1[/tex]

[tex](\frac{y}{5})^2+(\frac{x}{5})^2=1[/tex]

[tex]\frac{x^2}{5^2}+\frac{y^2}{5^2}=1[/tex]

Multiply both sides by 5^2:

[tex]x^2+y^2=5^2[/tex]

This is a circle with center (0,0) and radius 5.

All I did to get that was compare our rectangular equation we found to

Answers

Answer:

y = 1

Step-by-step explanation:

Given function is:

[tex]\frac{x^2+8x+3}{x^2+3x+1}[/tex]

In order to find the horizontal asymptote, the coefficients of highest degree variable of numerator and denominator are divided.

In our case,

both the numerator and denominator have 1 as he co-efficient of x^2

So the horizontal asymptote is y = 1/1

Hence, third option y=1 s correct ..

Final answer:

The correct horizontal asymptote for the given rational expression is y = 1, found by comparing the degrees and leading coefficients of the numerator and denominator.

Explanation:

For the expression y = (x² - 8x + 3) / (x² + 3x + 1), the correct horizontal asymptote is determined by looking at the degrees of the polynomials in the numerator and the denominator. When the degrees are the same, the horizontal asymptote is found by dividing the leading coefficients. In this case, both polynomials are of degree 2, and the leading coefficients are both 1. Thus, the horizontal asymptote is y = 1.

Write an equation: The sides of a rectangle are x and ( x - 4 ). The perimeter is 87

Answers

The perimeter of a rectangle, is all of the sides added up.

In a rectangle, there are two widths (right and left), and two lengths (up and down)

So:

Perimeter = 2 × width + 2 × length.

To get the equation we just substitute in the values that we are given:

length = (x)

width = (x - 4)

perimeter = 87

So just put these values into:  perimeter = 2 × width + 2 × length:

87  =  2(x) + 2(x - 4)

_____________________________

Answer:

The equation is:       87 = 2(x) + 2(x - 4)

(note: this can be simplified down like so:

87 = 2x + 2x - 8

87 = 4x - 8

Next you know that after every minute, the balloon goes down 150 ft. So that means -150 ft per minute. Now put it together, the equation is written as "y = 150m+2250" (since m is the required variable, that's what is written in the equation instead of x).

Next, to make a table, you need to determine what value goes in the left side, the x values (the independent variables) and what goes in the right side, the y values (the dependent variables). The two variables here are Height and Time. Time is not dependent on the height of the balloon-- the height depends on how much time has passed. So Time on the left and height on the right. Next just plug in the values 6, 8, and 10 into your equation. Your answer will be the output, aka the height of the hot air balloon after x minutes.

Your table should look something like this:

m       y

6       1350

8       1050

10       750

Hope this helps :)

Solve for variable: 5z/8 – 1/3 = 2/5

Answers

Answer: z= .6

Step-by-step explanation:

Numerator: When you do 5•.6, you get 3, and then 3-1 equals 2.

Denominator: 8 - 3 = 5.

Therefore you get 2/5 which makes z = .6

Find the average rate of change for the given function from x = 1 to x = 2.
1) -2
2) -1/2
3) 1/2
4) 2

Answers

Answer:

2

Step-by-step explanation:

The average rate of change from x=1 to x=2 is the same as finding the slope of a line at x=1 and x=2.

So we are going to need to corresponding y coordinates.

What y corresponds to x=1? y=3

What y corresponds to x=2? y=5

So we have the ordered pairs (1,3) and (2,5).

Line the points up vertically and subtract vertically then put 2nd difference over 1st difference.

(2 , 5)

-(1  , 3)

-----------

1      2

The average rate of change is 2/1 or just 2.

Now since we were asked to find the average rate of change given the function was a line, it really didn't matter what two points you used on that line.

Answer: Fourth option

[tex]m=2[/tex]

Step-by-step explanation:

If we call m the average change rate of a function between [tex]x_1[/tex] and [tex]x_2[/tex], then, by definition:

[tex]m=\frac{f(x_2)-f(x_1)}{x_2-x_1}[/tex]

In this case the function is the line shown in the graph. Then we look for the values of [tex]y = f (x)[/tex] for [tex]x = 1[/tex] and [tex]x = 2[/tex]

When [tex]x=1[/tex] then [tex]f(x)=3[/tex]

When [tex]x=2[/tex] then [tex]f(x)=5[/tex]

Therefore

[tex]m=\frac{5-3}{2-1}[/tex]

[tex]m=\frac{2}{1}[/tex]

[tex]m=2[/tex]

Which statement is true regarding the graphed functions?

Answers

Answer:

Option A) f(2)=0 and g(-2)=0

Step-by-step explanation:

we know that

The vertex of f(x) is equal to (2,0)

The vertex of g(x) is equal to (-2,0)

step 1

Find the value of f(x) and g(x) for x=2

Observing the graph

For x=2

f(2)=0 ----> the y-coordinate of the vertex

g(2) > 12

step 2

Find the value of f(x) and g(x) for x=-2

Observing the graph

For x=-2

f(-2)> 12

g(-2)=0 ----> the y-coordinate of the vertex

therefore

The statement that is true regarding the graphed functions is

f(2)=0 and g(-2)=0
