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

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.

√3+ √11 is greater than 5 .

We first assume that √3+ √11 is greater than 5. Then we check if our assumption is correct.

So suppose that √3+ √11 > 5

Squaring on both sides and using the identity [tex](a+b)^2=a^2+b^2+2ab[/tex],

⇒ 14 + 2√33 > 25

Subtracting 14 from both sides,

⇒ 2√33 > 11

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

If Mr. Jackson has a circular garden with a diameter of 10 feet surrounded by edging and using the same length of edging, he is going to create a square garden, then the maximum side length of the square is equal to 7.85 feet.

First, we have to find the amount of edging Mr. Jackson has. This can be calculated by finding the circumference.

Circumference can be found by using diameter by the formula;

c = π (diameter)

c = π (10)

c = 3.416 feet

This is the amount of edging on the circular garden. As he has to use the same amount of edging on the square garden, the edging on the square garden is the parameter of the square garden. As the parameter of the square is four times the side length, therefore;

3.416 ÷ 4 = 7.85

Hence, the maximum side length of the square is equal to 7.85 feet.

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

14. The slope is of -4/3.

The endpoints are given as follows:

CD = sqrt(25) = 5.

The length is of 5 units.

The midpoint is the mean of the coordinates, hence:

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

Hans will run additional 9 miles to the 18 miles he has run to complete 27 miles in wants to run for the week.

If Hans is to run 27 miles this week and he has run 18 miles, the additional miles he has to run in the week is t. Meaning that t plus eighteen is equal to 27, which is expressed mathematically below

t + 18 = 27

To solve the equation above, use balancing method. To use balancing method, subtract 18 from both side of the equation.

t +18 -18 = 27-18

t + 0 = 27-8

t = 27 -18

t = 9

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
