The International Space Station orbits 350 km above Earth’s surface. Earth’s radius is about 6314 km. Use the Pythagorean Theorem to find the distance from the space station to Earth’s horizon. Round your answer to the nearest kilometer. (Diagram is not to scale.)
Answers
Answer:
2131 km
Step-by-step explanation:
The Pythagorean theroeom states that a^2+b^2=c^2. We know that Earth's radius is 6314, so we know one of the shorter sides, (a). side c, the hypotenuse, is 6314 km plus 350 km. Plug it into the equation and then solve for b.
6314^2+b^2=6664^2
b^2=4542327

t=bd+M solving M what's the answer
Answers
Answer:
m=−bd+t
Step-by-step explanation:
t=bd+m
flip equation
bd+m=t
Step 2: Add -bd to both sides.
bd+m+−bd=t+−bd
m=−bd+t
On solving for M, we get -
M = t - bd
We have the following expression -
t = bd + M.
We have to solve for ' M '.
Solve for x : nx + a = [tex]$\pi[/tex].On solving, we get -

According to the question, we have -
t = bd + M
t - bd = M
M = t - bd

Step 1: 12x – 15 – 12x = 7x + 20
Step 2: 12x – 12x – 15 = 7x + 20
Step 3: -15 = 7x + 20
Step 4: -35 = 7x
Step 5: -5 = 3
Drag and drop the correct justification for each step.
Answers
Step-by-step explanation:
step 1. 12x - 15 - 12x = 7x + 20
step 2. 12x - 12x - 15 = 7x + 20 (grouping of terms)
step 3. -15 = 7x + 20 (adding like terms)
step 4. -35 = 7x (subtract 20 from both sides)
step 5. this step is incorrect.
step 6. -5 = x ( divide both sides by 7)
step 7. x = -5 (put the variable first).

A Cepheid variable star is a star whose brightness alternately increases and decreases. Suppose that Cephei Joe is a star for which the interval between times of maximum brightness is 6 days. Its average brightness is 3.5 and the brightness changes by /-0.25. Using this data, we can construct a mathematical model for the brightness of Cephei Joe at time t, where t is measured in days: B(t)=4.2 +0.45sin(2pit/4.4)
A) Find the rate of change of the brightness after t days.
B) Find the rate of increase after one day.
Answers
Answer:
a) The rate of change of the brightness after t days is [tex]B^{\prime}(t) = 0.204525\pi\cos{(0.4545\pi t)}[/tex]
b) The rate of increase after one day is of 0.0915.
Step-by-step explanation:
The brightness after t days is given by:
[tex]B(t) = 4.2 + 0.45\sin{(\frac{2\pi t}{4.4})} = 4.2 + 0.45\sin{(0.4545\pi t)}[/tex]
A) Find the rate of change of the brightness after t days.
This is [tex]B^{\prime}(t)[/tex]
The derivative of a constant is 0, the derivative of [tex]\sin{at}[/tex] is [tex]a\cos{at}[/tex]
So, in this case, we have that:
[tex]B^{\prime}(t) = 0.45*0.4545\pi\cos{(0.4545\pi t)} = 0.204525\pi\cos{(0.4545\pi t)}[/tex]
The rate of change of the brightness after t days is [tex]B^{\prime}(t) = 0.204525\pi\cos{(0.4545\pi t)}[/tex]
B) Find the rate of increase after one day.
This is [tex]B^{\prime}(1)[/tex]. So
[tex]B^{\prime}(1) = 0.204525\pi\cos{(0.4545\pi)} = 0.0915[/tex]
The rate of increase after one day is of 0.0915.

Angle B and Angle D are both 101 degrees
Step-by-step explanation:
Consecutive Angles in a parallelogram are supplementary (add up to 180 degrees).
Given that fact, we can deduce the measure of angle B.
180-79=101.
Angle D has the same setup since Angle D and C are consecutive along with Angle C and B.
180-79=101.
Therefore, both Angle B and D are 101 degrees.

Answer:

Step-by-step explanation:
The triangle provided is an equilateral one, which means that the length of all sides is equal.
Let's start by taking two and finding x.
8x+1 = 3x+6 (Subtract 3x from both sides)
5x+1 = 6 (Subtract 1 from both sides)
5x = 5 (Divide 5 from both sides)
x = 1
Now we substitute x in all the equations to find the length.
8(1) + 1 = 9
3(1) + 6 = 9
4(1) + 5 = 9
Length = 9

Sorry all i could do was reflect the coordinates across the x-axis.
The figure reflected along x-axis will have vertices A(1, -2), B (3, -6), C(-1, -2), and D(-2, 2).
What is reflection along the x-axis?When we reflect a figure along the x-axis the coordinate point of y changes its sign, (x, y) becomes (x, - y).
Think of holding the x-axis with two fingers and rotating it.
Given, we reflect a figure with vertices A(1,2) B (3,6), C(-1,2), and D(-2,-2)
across the x-axis.
∴ The rotated coordinate will be A(1, -2), B (3, -6), C(-1, -2), and D(-2, 2).
