Let x be the speed she rows upstream.

Upstream

speed = distance / time

x = 4 / t.................................(1)
downstream
x + 5 = 6 / t...........................(2)
from  (1)
t = 4/x
Substituting in (2):-
x + 5 = 6 / (4/x)
x + 5 = 3x / 2
2x + 10 = 3x
x = 10 

ANSWER IS  rowing rate upstream is 10 mph and downstream its 15 mph.

What’s the inverse of y= 100 - x^2
Marianna [84]

Answer:

The inverse is ±sqrt(100-x)

Step-by-step explanation:

y= 100 - x^2

Exchange x and y

x = 100 -y^2

Solve for y

Subtract 100 from each side

x-100 = 100-100-y^2

x-100 = - y^2

Multiply by -1

-x+100 = y^2

100 -x = y^2

Take the square root of each side

±sqrt(100-x) = sqrt(y^2)

±sqrt(100-x) = y

The inverse is ±sqrt(100-x)

A cube has a surface area of 24 ft squared .What is the length of on edge of the cube?
Vinil7 [7]

Surface area= 24 ft^2

A cube has 6 faces, so the surface area of 1 face would be 24/6, which is 4 ft^2.

The formula for the area of a square is l x w, but in a square both are equal so you're essentially squaring one side.

Therefore, the area of a square ( 4 ft^2 ) can be square-rooted in order to find the length of an edge.

\sqrt{4} = 2

Therefore, the length of 1 edge of the cube is 2 ft

Et f(x) = x2 + 6 and g(x) g(x) x+8/x . Find ( g o f)(­ -7)
earnstyle [38]

Answer:

A

Step-by-step explanation:

A function composition is where one function is substituted within another function and is written g(f(x)). Here we will substitute f(x) into g(x). For g(f(-7)), we substitute -7 for x.

\frac{x^2+6+8}{x^2+6}

Now substitute -7 for x.

\frac{x^2+6+8}{x^2+6} = \frac{(-7)^2+6+8}{(-7)^2+6}=\frac{49+6+8}{49+6}=\frac{63}{55}
