Answer:

314 mi^2 (3 s.f.)

Step-by-step explanation:

$surface \: area \: of \: sphere = 4\pi {r}^{2}$

diameter of sphere= 10mi

radius of sphere= 10÷2= 5mi

Surface area of sphere= 4(pi)(5^2)= 100pi= 314mi^2 (3 s.f.)

What is an equation of the line that is perpendicular to y= −3/4x +6 and passes through the point (3, 9) ?

olga2289 [7]

Perpendicular lines have opposite reciprocals from the original line.

Original line: y=-3/4x+6

Perpendicular line: y=4/3x+b

Solve for b by plugging in the given coordinates (3,9) for x and y respectively.

9=4/3(3)+b

Multiply 4/3*3.

9=4+b

Subtract 4 from both sides.

5=b

Now, with b and the slope, you can write the equation:

y=4/3x+5

I hope this helps :)

Step-by-step explanation:

Let alpha be the unknown angle. We can set up our sine law as follows:

$\frac{ \sin( \alpha ) }{5 \: m} = \frac{ \sin(42) }{3.6 \: m }$

$\sin( \alpha ) = \frac{5 \: m}{3.6 \: m} \times \sin(42) = 0.929$

Solving for alpha,

$\alpha = arcsin(0.929) = 68 \: degrees$
