Answer:

MP ⊥ LO ⇒ proved

Step-by-step explanation:

In the given figure

∵ m∠LPM = m∠MNO ⇒ given

∵ m∠MNO = m∠MPO ⇒ given

→ If the measure of an angle equals the measures of another two

   angles, then the two angles must be equal in measures

∴ m∠LPM = m∠MPO ⇒ proved

∵ P ∈ line LO

∵ ∠ LPM and ∠MPO are adjacent angles

∴ ∠LPM and ∠MPO formed a pair of linear angles

→ The measure of the linear pair angles is 180°

∴ m∠LPM + m∠MPO = 180°

∵ m∠LPM = m∠MPO

→ That means the measure of each one is 180° divided by 2

∴ m∠LPM = m∠MPO = 180° ÷ 2

∴ m∠LPM = m∠MPO = 90°

∵ MP intersect LO at P and formed right angles at P

→ That means MP is perpendicular to LO

∴ MP ⊥ LO ⇒ proved

Step-by-step explanation:

1) The reflected function [tex]g(x)=-2(3.5)^x[/tex] is defined everywhere.

2) Initial value of g(x) or g(0) is 1

3) Value of g(1) is -7

4) Value of g(-1) is -4/7

The given function is:

[tex]y=2(3.5)^x[/tex]

We know that when a function is reflected about the x-axis,

y becomes -y while x is unchanged.

So, the reflection of [tex]y=2(3.5)^x[/tex] about x-axis is:

[tex]-y=2(3.5)^x[/tex]

[tex]y=-2(3.5)^x[/tex]

[tex]g(x)=-2(3.5)^x[/tex]

g(x) is an exponential function defined everywhere.

[tex]g(0) =-2[/tex]

[tex]g(1) =-7[/tex]

[tex]g(-1) =-\frac{4}{7}[/tex]

Therefore, 1) The reflected function [tex]g(x)=-2(3.5)^x[/tex] is defined everywhere.

2) Initial value of g(x) or g(0) is 1

3) Value of g(1) is -7

4) Value of g(-1) is -4/7

Step-by-step explanation:

Answer:

x = 57

Step-by-step explanation:

1. Look at the expression (x + 22). It's measurement the upper side of the lines. We know that if we add up all sides, we will get a full circle, or a value of 360. We know that if I extend the blue line to the left on the upper parallel line, it would equal 180 degrees.

We can express this as x + 22 = 180. Now lets look at the bottom equation, notice that the 2x - 13 is the missing side of x + 22. So we know:

x + 22 + 2x - 13 = 180

3x + 22 - 13 = 180

3x + 9 = 180

3x = 171

x = 57

2. We can check this by plugging it into our formula. x + 22 and 2x - 13. so 57 + 22 = 79 and 2(57) - 13 = 101. Add them together: 79 + 101 = 180.

3. We know this is true because both angles combined will be to form 180 degrees. For a better understanding, view the image I sent you. 1 = 3, and 4 = 2. Opposite angles are equal. In your equation, we have 3 and 8. we KNOW that 8 = 2. And we also know that adding up 2 + 3 MUST equal 180 degrees.

Answer:

1.61 x km= y miles  

x km= y/ 1.61 miles

Step-by-step explanation:

Let x represent the distance in Kilometers  and y represent the distance in miles then

1.61 x km= y miles

Now if we have 5 miles then

1.61(5) km = 5miles

8.05 km = 5 miles

Similarly if we want to express 1 km in miles the equation would be

x km= y/ 1.61 miles

So for 5 km the miles would be

5 km = 5/1.61 miles

5 km = 3.1055 miles

because u add z with b divided by 37

After 22 days and 8 hours (0.349×24 hours) and 22 minutes (0.376×60 minutes) and 34 seconds (0.56×60 ≈ 34), the number of daily hits reaches 1,000,000.

It is given that the website hosting the song uses the function:

[tex]\rm f(t) = 2002t^2[/tex]    to represent the number of daily hits over time, where t is time in days.

It is required to predict the day on which the number of daily hits reaches 1,000,000.

It is defined as a special type of relationship and they have a predefined domain and range according to the function.

We have a function:

[tex]\rm f(t) = 2002t^2[/tex]

When f(t) = 1,000,000 then what will be the value of 't'

Simply:

[tex]\rm 1,000,000 = 2002t^2\\\rm 499.500 = t^2\\\rm \sqrt{499.500} = t\\\rm t = 22.349\ Days[/tex]

t = 22 days and 8 hours (0.349×24 hours) and 22 minutes (0.376×60 minutes) and 34 seconds (0.56×60 ≈ 34).

Thus, after 22 days and 8 hours (0.349×24 hours) and 22 minutes (0.376×60 minutes), and 34 seconds (0.56×60 ≈ 34), the number of daily hits reaches 1,000,000.

The day on which the number of daily hits of the considered song for the specified website reaches 1,000,000 is 23rd day.

You can simply replace those variables with the value you know of them and then operate on those values to get a final value. This is the result of that expression at those values of the considered variables.

So, suppose the day is t = d (dth day from the launch of the song) on which the daily hits reaches 1,000,000.

Then, evaluating the function [tex]f(t) = 2002(t^2)[/tex] at t = d should give us 1000000

Putting it, we get:

[tex]f(d) = 1000000\\2002(d^2) = 1000000\\\\\text{Dividing both the sides by 2002}\\\\d^2 = \dfrac{1000000}{2002}\\\\d = \sqrt{\dfrac{1000000}{2002}}\approx 22.35[/tex]

So after 22th day, ie on 23rd day (as 22.35 = 22 + 0.35 which shows 23rd day is still not completed) of the launch of the song, the number of daily hits reaches 1,000,000.

Thus, the day on which the number of daily hits of the considered song for the specified website reaches 1,000,000 is 23rd day.

Answer:

y = 10x - 6

Step-by-step explanation:

If we know the function is linear then we can use any two coordinate pairs to find the slope of the line.

Note that the first pair is (0, -6) and the last pair is (4, 34).  The 'run' is from x = 0 to x = 4, a 'run' of 4.  The 'rise' is from -6 to34, a 'rise' of 40.  Thus, the slope of this line is m = rise / run = 40/4 = 10.

Again using the coordinate pair (0, -6), along with the slope-intercept form of the equation of a straight line, we get:

-6 = 10(0) + b, so we know that b = - 6 and that the equation of this line must therefore be:

y = 10x - 6

The required slope-intercept form of the function is y = 10x - 6.

The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.

Here,
m = (y₂ - y₁) /  (x₂ - x₁)
Substitute 2 pairs from the table in the above equation,
m = (4 + 6)/(1-0)
m = 10
Now put the slope and one pair in the slope-intercept form of the equation

y - y₁ = m (x - x₁)
y + 6 = 10(x - 0)
y = 10x - 6

Thus, the required slope-intercept form of the function is y = 10x - 6

The bar that represents the bar that would be the largest in a histogram would be 2/15.

To identify the bar that would be the largest in a histogram we must take each of the options and perform the division to obtain a decimal number. Once we have all the decimal numbers, we must identify which is the largest of them and thus we will know which one would represent a larger bar in a histogram. Here is the procedure:
