Answer:

-1ab^2 + 5b + 8

Step-by-step explanation:

3a^2+9ab+5-4a^2-4ab+3

3a^2-4ab^2=-1ab^2

9ab-4ab=5ab

5+3=8

-1ab^2+5ab+8

3. Write an equation of a line that is perpendicular to the line x – 2y = 8.
xenn [34]

Answer:

y=0.5x+40

Step-by-step explanation:

Copy the  equation.

x-2y=8

Subtract x from both sides.

-2y=-x-8

Divide both sides by -2.

y=0.5x+4

Now we know the slope is 0.5.

Any line with a slope of 0.5 will be perpendiculr to the original line.

One that you can use is y=0.5x+40.

The graph of the parent function y = x cubed is horizontally stretched by a factor of One-fifth and reflected over the y-axis. W
sasho [114]

Answer: OPTION D.

Step-by-step explanation:

Below are some transformations for a function f(x):

If -f(x), then the function is reflected over the x-axis.

If f(-x), then the function is reflected over the y-axis.

If f(bx)  and b>1, then the function is horizontally compressed.

If  f(bx)  and 0 < b, then the function is horizontally stretched.

In this case you know that the parent function is:

y=x^3

According to the information given in the exercise, the parent function IS horizontally stretched by a factor of \frac{1}{5} and it is also reflected over the y-axis.

Therefore, based on the transformations explained before, you can notice that the transformation is:

f(-bx)

Where 0 < b

Therefore, the equation of the transformed function is:

y=(-\frac{1}{5}x)^ 3

A blimp provides aerial tv views of a soccer game. The camera sights the stadium at a 7 degree angle of depression. The altitude
maria [59]

Given that,

The camera sights the stadium at a 7 degree angle of depression.

The altitude of the blimp i slide 300 m.

To find,

The line of sight distance from the camera to the stadium.

Solution,

If we consider a right angled triangle. Let x is its hypotenuse i.e. the line of sight distance from the camera to the stadium. Using trigonometry :

\sin\theta=\dfrac{P}{x}\\\\x=\dfrac{P}{\sin\theta}\\\\=\dfrac{300}{\sin7}\\\\=2461.65\ m

So, the line of sight is at a distance of 2461.65 m from the camera to the stadium.
