Step-by-step explanation:

Firstly you should times the first decimal of the column by the number that is the numerator. So the second column the numerator is 2 so you times the first number by 2 which gives you 0.10. You do this for every column then you get you answer.

After rationalizing the denominator for the expression √3 x / 2y, we get that the result is [√6xy)] / 2y.

The removal of a radical or imaginary number from the denominator of an algebraic fraction is referred to as rationalization. That is, eliminate the radicals from a fraction to leave only a rational integer in the denominator.

Rationalizing the divisor suggests that you get eliminate the novel within the divisor. 

by the rules of radicals, We can rephrase this as √(5x) / √(2y)

The expression will then be multiplied by √(2y) / √(2y).  Keep in mind that this results in 1, and multiplying this by the first expression has no effect on the original issue.

On multiplying we get-

[√(3x) * √(2y)] / [√(2y) * √(2y)]

[√6xy)] / 2y 

Therefore, after rationalizing the denominator for the expression √3 x / 2y, we get that the result is [√6xy)] / 2y.

If the observation deck is 871 feet high, the horizontal distance from the base of the skyscraper out to the ship is: 784.25 feet.

Given:

Angle of depression (∅) = 48°

Opposite side = 871 feet

Let x represent the horizontal distance

Hence,

tan 48° =871/x

x = 871/tan 48°

x= 871/ tan(0.8377)

x= 871/ 1.1106125

Answer:

Step-by-step explanation:

Ok, so this is a conversion problem and it wants you to get 45 euros to whatever amount of dollars that equals. So first, you need to get the conversion rate.

1 euro/1.14 dollars

Now, plug in the 43 Euros to the front of the conversion rate

43 euros (1 euro/1.14 dollars)

You want what you start with on the bottom of the conversion factor, so switch the rate around

43 euros (1.14 dollars/1 euro)

Then, multiply what is on top, then divide by what is on the bottom.

49.02 dollars/1=49.02 dollars

The euros go away because they cancelled out.

For line segment CD, we have that:

10. The length is of 5 units.

12. The midpoint is of (0.5,0).

14. The slope is of -4/3.

The endpoints are given as follows:

c(-1,2) and d(2,-2).

The length is given by the distance between the two endpoints, hence:

[tex]CD = \sqrt{(2 - (-1))^2+(-2-2)^2}[/tex]

CD = sqrt(25) = 5.

The length is of 5 units.

The midpoint is the mean of the coordinates, hence:

The midpoint is (0.5,0).

The slope, taking two points, is given by change in y divided by change in x, hence:

m = (-2 - 2)/(2 - (-1)) = -4/3.

The composition of f(x) and g(x) gives:

(f ◦ g) (x) =  x²  + 9x + 20

Here we have the two functions:

f(x) = x² + 5x +6

g(x) = x +2

And we want to find the composition:

(f ◦ g) (x)

The composition means that we need to evaluate f(x) in g(x), so we get:

(f ◦ g) (x) = f( g(x))

Then we will get:

(f ◦ g) (x) = g(x)² + 5*g(x) +6

Now, replacing g(x) we get:

(f ◦ g) (x) = (x + 2)² + 5*(x + 2) + 6

Expanding that, we get:

(x + 2)² + 5*(x + 2) + 6 = x² + 4x + 4 + 5x + 10 + 6 = x²  + 9x + 20

It follows from the task content that the midpoint of the line segment joining the two points (-3, 8) and (-8, 2) is to be determined.

Since the midpoint of a line is given by coordinates;

x = (x1 + x2)/2 and y = (y1 + y2)/2.

It follows that we have;

x = (-3+(-8))/2

x = -11/2

Answer:

[tex](5,\, -2)[/tex].

Step-by-step explanation:

For a line segment in a plane, the [tex]x[/tex]-coordinates of the midpoint is the average of the [tex]x\![/tex]-coordinates of the endpoints. Likewise, the [tex]y[/tex]-coordinates of the midpoint is the average of the [tex]y\![/tex] coordinates of the endpoints.

For example, the midpoint of the line segment joining [tex](x_{a},\, y_{a})[/tex] and [tex](x_{b},\, y_{b})[/tex] is:

[tex]\begin{aligned} \left(\frac{x_{a} + x_{b}}{2},\, \frac{y_{a} + y_{b}}{2}\right)\end{aligned}[/tex].

In this question, [tex]x_{a} = 8[/tex], [tex]x_{b} = 2[/tex], [tex]y_{a} = (-5)[/tex], [tex]y_{b} = 1[/tex]. Thus, the midpoint of the line segment joining the two points would be:

[tex]\begin{aligned} \left(\frac{8 + 2}{2},\, \frac{(-5) + 1}{2}\right)\end{aligned}[/tex].

Simplify to obtain:

[tex]\begin{aligned} \left(5,\, -2\right)\end{aligned}[/tex].

Hence, the midpoint of the line segment joining [tex](8,\, -5)[/tex] and [tex](2,\, 1)[/tex] would be [tex](5,\, -2)[/tex].

What is a rational number?

Any real number that can be represented in the form of p/q, where q is not equal to 0 is called a rational number. The decimal expansion of rational numbers is terminating and repeating.

Simplifying the rational expression: 6c² + 9c / 3c

Given a rational expression,

6c² + 9c / 3c

On simplifying, we get,

For numerator, 6c² + 9c: 3c (2c + 3)

For denominator, 3c

Now, 6c² + 9c / 3c = 3c (2c + 3) / 3c

= 2c + 3

Step-by-step explanation:

a ratio of 5:5:6 tells us first that there are 5+5+6 = 16 units in all the sides lengths of the triangle.

we don't know how large a single unit is yet, but we know, we have 16 of them.

we also know that all 3 sides together is 32 cm.

and that is another form to bring all side lengths together.

so, we know now that

32 cm = 16 ratio units.

therefore, one ratio unit is 32/16 = 2cm.

therefore, the sides are actually :

2×5 = 10 cm

2×5 = 10 cm

2×6 = 12 cm

so, we have an isoceles triangle (the 2 legs are equally long : 10 cm) with a baseline of 12 cm.

that means the height to the baseline splits the triangle in half (into 2 equal right-angled triangles).

and the height of the main triangle we get via Pythagoras from these smaller triangles :

c² = a² + b²

with c being the Hypotenuse (the baseline opposite of the 90° angle), a and b are the legs.

10² = (baseline/2)² + height² = 6² + height²

100 = 36 + height²

64 = height²

height = 8

the area of a triangle is

baseline × height / 2

so, in our case the area of the triangle is

12 × 8 / 2 = 12 × 4 = 48 cm²

We get the composite function for the relationship between area and time as A = π (16t + r )².

We are given that, the wave travels at a rate of 16 feet / sec when George jumps off a tire swing in the circular pond.

So, this means that the radius of the wave increases by 16 feet in every second.

Now, we know that, the area of circle is given by:

A = π r²

Now, r increases by 16 feet every second.

So, the composite function will become:

A = π (16t + r )²

where 16 t represents the increase in area in t seconds.

Therefore, we get the composite function for the relationship between area and time as A = π (16t + r )².

Step-by-step explanation:

The slope can be found as the quotient or rise/run.

Rise - difference of y-coordinates of two points, run - difference of x-coordinates of same two points.

Find the slope using the first two pairs of coordinates in the table:

The y-intercept is the point of intersection of the line with the y-axis.

This point has x = 0 coordinate. On the table we can see the corresponding y- coordinate is  - 2:

The equation of the line is obtained by substituting the values of m and b into slope-intercept form:

The slope is 1/3 and the y-intercept is -2, so the equation is:

y = (1/3)*x - 2

if we use the first two pairs on the table we get:

(-3, -3) and (0, -2)

Then the slope of the linear relation will be:

a = (-2 - (-3))/(0  - (-3)) = (-2 + 3)/3 = 1/3

The slope is 1/3.

We can see that the point (0, -2) is on the table, so the y-intercept is y = -2

How to write the equation?

The linear equation in the slope-intercept form is:

y = a*x + b

Where a is the slope and b is the y-intercept.

Then we will get:

y = (1/3)*x - 2
