Step-by-step explanation:

This line is the best fit for the scatter plot because it touches a lot more points than the second

Answer:

The first line

Step-by-step explanation:

Hey there!

Well the first lie is a positive slope just like the dots whereas,

the second line is a negative slope.

Therefore, the first line is the line of best fit.

Answer:

Step-by-step explanation:

The second answer choice correctly shows the result of multiplying functions m and n together.

Answer:

3 quarts.

Step-by-step explanation:

The wall is 20 feet by 15 feet. That means the area of the wall is 20 * 15 = 300 feet squared. Since one quart of paint covers 100 square feet, they will need to purchase 300 / 100 = 3 quarts of paint.

Answer:

Third grade secondary = 87 students

Step-by-step explanation:

First grade = 30/100 x 250 = 75 students

Second grade = 35/100 x 250 = 87.5 rounded off to 88 students. Because students can't be half thus can't be in decimal. So round off to the nearest whole number.

Third grade = 250 - 88 - 75 = 87 students

Answer:

third grade secondary = 87 students

Answer:

a) ◇G = ◇H - T◇S wiĺl be negative.

b) It will be a spontaneous reaction.  

Explanation:

As ◇H is less than 0 and T◇S is greater than 0 so if we put it in the equation we would get the negative maximum result. And when the energies are with negative sign they are said to be spontaneous.

Answer:

20

Step-by-step explanation:

We know that ΔBAC and ΔBED are similar becuase of the AA Postulate (they both have a right angle and they both share ∠B). Since AC is 15/3 = 5 times longer than ED, the scale factor is 5 which means AB is 5 times longer than EB. This makes EB = 25 / 5 = 5. Since AB = AE + EB and we know that AB = 25, AE = x and EB = 5, 25 = x + 5 which means x = 20.

Answer:

48-20

Step-by-step explanation:

The distance of the surveyor from the bottom of the building is  125.1 feet.

You look straight parallel to the ground. But when you have to watch something high, then you take your sight up by moving your head up. The angle from horizontal to the point where you stopped your head is called the angle of elevation.

Assume the distance of the surveyor from the bottom of the building is represented by x.

First, we have to know that the Tan of 48° is equal to 1.11.

The equation to get the distance will then be;

tan(48) = 50/h

h = 45.05  feet

Now, tan(20) = 45.05  /x

x = 45.05  / 0.36

x = 125.1 feet

The distance of the surveyor from the bottom of the building is  125.1 feet.

Circumference of the circle = 2 x pi x r

= 2 x 3.14 x 26.85

= 168.618 Inches

after rounding to nearest tenth, 168.6 inches

Answer:

168.6 inches

Step-by-step explanation:

The formula for finding the circumference of a circle is:

[tex]\pi r2[/tex] (Basically multiplying [tex]\pi[/tex] by the diameter since the radius is half the diameter)

Let's substitute and solve!

3.14(26.85 × 2) =

f=10/3

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

Explanation:

Since the x coordinates are the same, we can subtract the y coordinates to get

1.5 - (-3.5) = 1.5 + 3.5 = 5

Note how subtracting a negative is the same as adding.

-------

We can subtract in the other order

-3.5 - 1.5 = -5

but we need to make this result positive. A negative distance is not allowed. Absolute value is applied to make the result positive

|-5| = 5

Answer:

[tex]f(x)=5x+12\\\\ f^{-1}(x):\\ y=5x+12\ \ \ |Subtract\ 12\\ y-12=5x\ \ \ |Divide\ by\ 5\\ \frac{y-12}{5}=x\\\\ f{-1}(x)=\frac{x-12}{5}[/tex]

Step-by-step explanation:

Answer:

f^-1(x) = x/5 - 12/5

Step-by-step explanation:

f(x) = 5x + 12

y = 5x + 12

x = 5y + 12

5y = x - 12

y = x/5 - 12/5

f^-1(x) = x/5 - 12/5

Hope that helped!!! k

Woah woah, no need to panic! I’ve got this taken care of for you!

1. 0.01 divided by 1,000= 100,000.000

Change the divisor 0.01 to a whole number by moving the decimal point 2 places to the right. Then move the decimal point in the dividend the same, 2 places to the right.

We then have the equations:

100000 ÷ 1 = 100,000.000

and therefore:

1,000 ÷ 0.01 = 100,000.000

Both calculated to 3 decimal places.

2. 0.012 divided by 100= 8,333.333

Change the divisor 0.012 to a whole number by moving the decimal point 3 places to the right. Then move the decimal point in the dividend the same, 3 places to the right.

We then have the equations:

100000 ÷ 12 = 8,333.333

and therefore:

100 ÷ 0.012 = 8,333.333

Both calculated to 3 decimal places.

3. 0.000851 divided by 10= 11,750.881

Change the divisor 0.000851 to a whole number by moving the decimal point 6 places to the right. Then move the decimal point in the dividend the same, 6 places to the right.

We then have the equations:

10000000 ÷ 851 = 11,750.881

and therefore:

10 ÷ 0.000851 = 11,750.881

Both calculated to 3 decimal places.

Answer:

Step-by-step explanation:

Answer:

y > 9

Step-by-step explanation:

The range of a function is the interval of all possible y-values that make the function true.

Here, one way to figure this out is to look at a graph of the function (see attachment).

From the graph, we can see that y-values approach very closely the value 9 and then the line rises beyond 9 forever. Thus, we can conclude that the range for f(x) is y > 9.

Answer:

option (c)

Step-by-step explanation:

g.f= g(f(x))

= (x2 -3)+1

=x2 -2

The composite function g.f is option c) x² - 2.

Functions which are formed by composing two or more functions in a way that one's output is another's input are called composite functions. They are also called function of functions.

Given: f(x) = x² - 3 and g(x)= x+1

The composite of the function;

g.f= g(f(x))

= g(x²-3)
