If the radius of the planet is given by R, and the height above the surface is given by h, use the figure below, and the Pythagorean Theorem to derive the formula for the distance, d, to the horizon tangent point, assuming that the triangle is a right triangle.
Please answer the second one too
Applying the pythagroean theorem, the formula to find the horizontal distance, d, is: [tex]\mathbf{d = \sqrt{h^2 - R^2} }[/tex]
What is the Pythagorean Theorem?The pyhagroean theorem is given as, c² = a² + b², where h is the longest side of the right triangle.
Given the following:
c = ha = db = RThe formula derived would be:
h² = d² + R²
Make d the subject fo the formula

The square root of an imperfect square
Step-by-step explanation:
find a three-digit number, which is 5 times greater than the product of its digits
Answer:
175
Step-by-step explanation:
How would one find a three-digit number which is 5 times as large as the product of its digits?
100a + 10b +c = 5abc
This shows that c must be a multiple of 5. Since it is a digit, c=5 ( c=0 does not work ).
Then:
100a + 10b + 5 = 25ab
This again shows that 10b+5 is a multiple of 25.
By testing all the digits, b=2 or b=7.
If b=2, then
100a + 25 = 50a
which has the solution a= -1/2, not a digit.
if b=7
100a +75 = 175a
Now the solution is a=1, so finally the number is 175. Indeed, 175 = 5*1*7*5.
Does that answer your question..?

The figure shows 2 right triangles, triangle A B C with right angle B and triangle B D C with right angle D. The measure of angle B A C is 45 degrees. The measure of angle D B C is 60 degrees. The length of side C A is 6 square root 2. The length of side B D is x.
Answer:
x=3
Step-by-step explanation:
I took the test and I got it right but if you want an explanation see bellow.
so triangle ABC is a 45- 45 -90 and we are given the hypotenuse of [tex]6\sqrt{2}[/tex]
and on a 45-45-90 triangle we know that the hypotenuse is always [tex]s\sqrt{2}[/tex] s standing for the lengths of both of the legs since they are both equal, so this tells us that line segment AB and BC are equal to 6, SO triangle BCD hypotenuse is equal to 6.Triangle BCD is a 60-90-30 triangle as we can tell by the measures given, and in a 60-90-30 triangle the hypotenuse is equal to S and it's shorter length known as line segment BD on this triangle is equal to [tex]\frac{s}{2}[/tex] and since we know s=6 we can do [tex]\frac{6}{2}[/tex] giving us our answer 3.
Using the sine ratio and the cosine ratio, the value of x in the given triangle is calculated as: x = 6.
How to Find the Value of x?Using the sine ratio, find BC:
sin ∅ = opposite/hypotenuse
Given the following:
∅ = 45°
hypotenuse = 6√2
opposite = BC
Substitute:
sin 45 = BC/6√2
sin 45 = BC/6√2
√2 = BC/6√2 [sin 45 = √2]
BC = √2 * 6√2
BC = 12 units
Use the cosine ratio to find x:
cos ∅ = adjacent/hypotenuse
Thus, we have:
cos 60 = x/12
1/2 = x/12 [cos 60 = 1/2]
2x = 12
x = 6.

This is because we know 100% that whoever we selected takes the bus, and we've shrunk down the population just these employees.
We have 8 males who take the bus out of 12+8 = 20 people who take the bus. Therefore, 8/20 = 0.40 represents the relative frequency of males who take the bus out of all bus commuters. In other words, 40% of the bus riders are male.

Which is an equation of the line that passes through the points (5,2) and (10,-3)?
A. y = x - 3
B. y = x - 8
C. y = -x + 7
D. y = -x + 12
Answer:
C
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (5, 2 ) and (x₂, y₂ ) = (10, - 3 )
m = [tex]\frac{-3-2}{10-5}[/tex] = [tex]\frac{-5}{5}[/tex] = - 1 , then
y = - x + c ← is the partial equation
to find c substitute either of the 2 points into the partial equation
using (5, 2 ), then
2 = - 5 + c ⇒ c = 2 + 5 = 7
y = - x + 7 ← equation of line

Maria bought 3 books for a total of $26. 25. How much did each book cost ?
Explanation -:In this question it is given that Maria bought 3 books and the cost of 3 books is $26.25. We are asked to calculate the cost of 1 book.
We can find the cost of 1 book by dividing the total cost by number of books.
Cost of 1 book = $26.25 ÷ 3 = [tex]\dfrac{26.25}{3}[/tex] = 8.75
Verifying -:Cost of 1 book = $8.75

write the equation polynomial whose graph contains the points (1,0),(-5,0),(-2,0),(-4,30)
Answer:
y = 3(x - 1)(x + 5)(x + 2)
Step-by-step explanation:
Given points: (1, 0) (-5, 0) (-2, 0) (-4, 30)
x-intercepts are when y = 0
Therefore, the x-intercepts are x = 1, x = -5 and x = -2
So (x - 1), (x + 5) and (x + 2) are all factors of the polynomial.
Therefore, the equation of the polynomial is:
y = a(x - 1)(x + 5)(x + 2) where a is a constant to be found
To find the constant a, input the point (-4, 30) into the equation and solve:
⇒ a(-4 - 1)(-4 + 5)(-4 + 2) = 30
⇒ a(-5)(1)(-2) = 30
⇒ 10a = 30
⇒ a = 3
Therefore, the equation of the polynomial is:
y = 3(x - 1)(x + 5)(x + 2)
