So we need to find the length of the hypotenuse of a right triangle with sides of 3 and 4, then add that distance to 3 and 4.

By the Pythagorean Theorme, the hypotenuse squared is equal to the sum of the sides squared...

d^2=3^2+4^2

d^2=9+16

d^2=25

d=√25

d=5

So the total distance of her run is 5+4+3=12 km

Modeling with Inverses

Rus_ich [418]

Step-by-step explanation:

I will do the first one as an example.

To find the inverse of y = f(x), simply switch x and y, then solve for y.

y = 3 + 2 ln x

x = 3 + 2 ln y

x − 3 = 2 ln y

(x − 3) / 2 = ln y

y = e^((x − 3) / 2)

So the inverse function is:

f⁻¹(x) = e^((x − 3) / 2)

The original function told us the amount of water as a function of time.

The inverse function tells us the time as a function of the amount of water.

A coach needs both small and large cones to set up an obstacle course. The coach knows that there are fewer than 30 cones in the

Pepsi [2]

Since they are FEWER than 30 total cones, the sum of x small cones and y large one must be LESS THAN 30: x+y <30
He needs AT LEAST a dozen (12), so that means that 12 will work or more than 12:
$y \geqslant 12$

What is the equation of the line that is parallel to the line y =1/3 x + 4 and passes through the point (6, 5)?

lianna [129]

Answer:

y = $\frac{1}{3}$ x + 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = $\frac{1}{3}$ x + 4 ← is in slope- intercept form

with slope m = $\frac{1}{3}$

Parallel lines have equal slopes , then

y = $\frac{1}{3}$ x + c ← is the partial equation

To find c substitute (6, 5) into the partial equation

5 = 2 + c ⇒ c = 5 - 2 = 3

y = $\frac{1}{3}$ x + 3 ← equation of parallel line
