Answer:
58.3°
Step-by-step explanation:
Missing Information:
In this question the diagram is missing Following are the attachment of diagram of the given question.
As we seen that the vertex c is making the right angle i,e 90° also there is an acute angle the Hypotenuse: 20 cm and the perpendicular is 10.5 cm
Now we have find the best approximation of the angle ABC used the cosx trigonometric function.
Putting the value of perpendicular and hypotenuse in the previous formula we get
Answer:
b = m(Px) -(Py)
Step-by-step explanation:
Solving the equation ...
y = mx + b
for b gives ...
b = mx - y
If the given point is (Px, Py), Sergio can find the y-intercepts using this equation.
For each slope (m), the corresponding y-intercept is ...
b = m(Px) -(Py)
Answer:
3031081 / 40678884
Step-by-step explanation:
To solve this, we can find the surface area of the moon and Earth, and then see how much the moon covers the Earth. The surface area of a sphere is equal to 4πr², so the radius of the Earth is
4πr² = 4 * π * 6378²
and the radius of the moon is
4πr² = 4 * π * 1741²
To figure out how much of the Earth's surface that the moon covers, we can implement a ratio of moons:Earth. This will give us an understanding of how many moons go inside one Earth. We thus have
(4 * π * 1741²) : ( 4 * π * 6378²) = (4 * π * 1741²) / ( 4 * π * 6378²)
cross out the 4 * π in the numerator and denominator
1741²/6378²
Next, we want to make the denominator 1, as that gives us 1 Earth. To do this, we can divide both the numerator and denominator by 6378². Because we are applying the same expression to both the numerator and denominator, this is essentially multiplying the fraction by 1, keeping it the same. We thus have
(1741²/6378²)/(6378²/6378²)
≈0.0745/1
≈ 0.0745
To put this in a fraction, we would have
(1741²/6378²)/1
= (1741²/6378²)
= 3031081 / 40678884
Answer:
C. -31
Step-by-step explanation:
To solve this problem, first you have to order of operations stands for PARENTHESIS, EXPONENTS, MULTIPLY, DIVIDE, ADD, and SUBTRACT the numbers from left to right. Please Excuse My Dear Aunt Sally!
First, parenthesis.
(4+2)=6
5-6²
Then, exponent.
6²=6*6=36
5-36
Subtract numbers from left to right.
5-36=-31
As a result, the correct answer is -31.
