Answer:
Step-by-step explanation:
BD is opposite the 30° angle. The sine of 30° is 0.5. The sin of an angle in a right triangle is opposite/hypotenuse so BD = sin 30°x8.
Now you have two known lengths The third can be found by applying the Pythagorean theorem: BC²+BD²=CD², from which you can establish a numerical value for BC.
To return back to -18°C from -10°C, you would have to lower the temperature by -8°C to compensate for the difference.
Hope that helps!
So you would find out what number in the 9 times tables goes into 25 and there's your answer x
The rational numbers will best define- The height of an airplane as it descends to an airport runway.
This is because it includes fractions as well.
Irrational, integers, whole numbers cannot be used in this situation.
For slope m and point (x₁, y₁), the point-slope equation of the line can be written as
y -y₁ = m(x -x₁)
You have m = -4 and (x₁, y₁) = (4, -9), so the equation of your line is
D. y+9 = -4(x-4)
