Answer:

=8/3m⁷n⁶

Step-by-step explanation:

Given the expression (2mn)⁴/6m⁻³n⁻², we first solve the numerator

(2mn)⁴ = 16m⁴n⁴

The new expression becomes 16m⁴n⁴/6m⁻³n⁻²

We now divide the coefficients and the exponents as follows:

=16/6ₓ(m⁴/m⁻³)×(n⁴/n⁻²)

Division between indices to the same base we subtract the powers.

4-⁻3=7

4-⁻2=6

=8/3m⁷n⁶

Answer:160

Step-by-step explanation:

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

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°

Hence, the measure of the center angle ∠AOC  is 160°.

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.

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

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.

Answer:

x=pi/3 + 2pi*k

x=2pi/3+2pi*k

Step-by-step explanation:

sin(x)=sqrt(3)/2

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

x=2pi/3+2pi*k

An equation is formed of two equal expressions. The solution to the equation sin(x)=√3/2 is (π/3 ± 2πn), (2π/3 ± 2πn), where n is any natural number.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

The solution of sinx=√3/2 are,

sin(x) = √3/2

x = sin⁻¹ √3/2

x = (π/3 ± 2πn), (2π/3 ± 2πn)

Hence, the solution to the equation sin(x)=√3/2 is (π/3 ± 2πn), (2π/3 ± 2πn), where n is any natural number.

Answer:

c. $280

Step-by-step explanation:

first you times the total profits by the percent that the girls get then the percent the boys get to find out how much of the profit the girls and boys basketball teams each get, then you subtract the profits the boys get by the profits the girls get to find out how much more the boys get than the girls.

7,115.03 x .07 = 498.0521

7,115.03 x .11 = 782.6533

782.6533 - 498.0521 = 284.6012

the boys receive 284.6012 more in profits than the girls

so c. $280 would be the best estimate of how much more the boys team will receive

equation: y=-150m+2250

Height after:

6 Minutes: 1350 ft

8 Minutes: 1050 ft

10 Minutes: 750 ft

Step-by-step explanation:

We know that the hot air balloon has an initial height of 2250 ft, so that is our y-intercept (in the equation, y =mx+b, the y-intercept is b). 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

Answer:

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]

There is a multiplication error

Step-by-step explanation:

Long division method is used to divide greater  number by a smaller number.

Here, greater number is known as the dividend and smaller number is known as divisor.

As per division algorithm,

Dividend = Divisor [tex]\times[/tex] quotient + remainder

Here, dividend = [tex]8x^3-36x^2+54x-27[/tex]

Divisor = [tex]2x-3[/tex]

Here, we need to find the error in the long division .

In step:

[tex]18x+27[/tex] , it should be 18x-27 as [tex]-3\times 9=-27[/tex] not +27

So, there is a multiplication error .

The correct option is c) she makes a multiplication error.

Step-by-step explanation:

Given :

Dividend = [tex]8x^3-36x^2+54x-27[/tex]

Divisor = [tex]2x-3[/tex]

Solution :

In step [tex]18x +27[/tex] there is mistake. It should be [tex]18x - 27[/tex] because [tex]-3 \times 9= -27[/tex] not +27.

Therefore the correct option is c) she makes a multiplication error.

Step-by-step explanation:

Answer:

9 geese

11 cows

Step-by-step explanation:

Say x is cows, and y is geese.

x + y = 20 animals

x * 4 + y * 2 = 62

x = 20 - y

(20 - y) * 4 + y * 2 = 62

80 - 4y + 2y = 62

- 2y = -18

y = 9 geese

x = 20 - 9 = 11 cows

Lisa has 11 cows and 9 geese.

To solve the problem involving Lisa's barn with 20 animals having 62 legs in total, and knowing she only has cows and geese, we can use a system of linear equations. We can denote the number of cows as c and the number of geese as g. Cows have 4 legs and geese have 2 legs.

We can then set up the following equations based on the information given:

Cows and geese equation: c + g = 20 (since there are 20 animals in total)

Legs equation: 4c + 2g = 62 (because cows have 4 legs and geese have 2 legs)

Now, let's solve the system of equations:

Multiply the first equation by 2 to match the number of geese legs in the second equation: 2c + 2g = 40

Subtract the modified first equation from the legs equation: (4c + 2g) - (2c + 2g) = 62 - 40, which simplifies to 2c = 22, and then c = 11. Lisa has 11 cows.

Substitute the number of cows back into the first equation to find the number of geese: 11 + g = 20, which leads to g = 9. Lisa has 9 geese.

Therefore, Lisa has 11 cows and 9 geese.

Step-by-step explanation:

I don't know where [tex]\theta[/tex] is so there is going to be two possibilities for cosine value, one being positive while the other is negative.

A Pythagorean Identity is [tex]\cos^2(\theta)+\sin^2(\theta)=1[/tex].

We are given [tex]\sin(\theta)=\frac{7}{25}[/tex].

So we are going to input [tex]\frac{7}{25}[/tex] for the [tex]sin(\theta)[/tex]:

[tex]\cos^2(\theta)+(\frac{7}{25})^2=1[/tex]

[tex]\cos^2(\theta)+\frac{49}{625}=1[/tex]

Subtract 49/625 on both sides:

[tex]\cos^2(\theta)=1-\frac{49}{625}[/tex]

Find a common denominator:

[tex]\cos^2(\theta)=\frac{625-49}{625}[/tex]

[tex]\cos^2(\theta)=\frac{576}{625}[/tex]

Square root both sides:
