It is a because each day you run 5 miles, meaning 100 miles is decreasing since you keep running the miles away, for example if you ran for 4 days 100-20, because we multiplied 4x 5( the amount of miles) and now we would have 80 miles to go

It would have to be the first option.

The second option is not correct because you are not adding more than what her goal is.

The third option is not correct because you are not dividing from her goal.

The fourth option is not correct because it would ultimately result in a negative number.

The first option is correct because it subtracts how many days she has ran times 5 from her goal. The resulting answer would show how many miles she has left to reach her goal of 100 miles during that month.

Hope this helps!

A. Solve the differential equation <img src="https://tex.z-dn.net/?f=y%27%3D2x%20%5Csqrt%7B1-y%5E2%7D%20" id="TexFormula1" title

$y' = \frac{dy}{dx}$

seperable differential equations will have the form
$\frac{dy}{dx} = F(x) G(y)$

what you do from here is isolate all the y terms on one side and all the X terms on the other
$\frac{dy}{G(y)} = F(x) dx$
just divided G(y) to both sides and multiply dx to both sides

then integrate both sides
$\int \frac{1}{G(y)} dy = \int F(x) dx

$

once you integrate, you will have a constant. use the initial value condition to solve for the constant, then try to isolate x or y if the question asks for it

In your problem,
$G(y) = \sqrt{1-y^2}

F(x) = 2x$

so all you need to integrate is
$\int \frac{1}{\sqrt{1-y^2}} dy = \int 2x dx$

The diameter of the Sun is 1.4 x 10⁶ km. The diameter of the planet Mars is 7000 km. What is the approximate ratio of the diamet

Lady bird [3.3K]

Answer:

C.) 2×10²

Step-by-step explanation:

(Sun dia) / (Mars dia) = (1.4 x 10⁶ km) / (0.7 × 10⁴ km) = (1.4/0.7) × 10²

The ratio of diameters is about 2 × 10².

_____

The applicable rule of exponents is ...

(a^b)/(a^c) = a^(b-c)

The diameter of Mars can be expressed several ways.

7000 = 7×1000 = 0.7×10,000 = 0.7×10⁴
