John is a trail runner who decides to take a day off work to run up and down a local mountain. He runs uphill at an average spee

lesantik [10]

Answer:

Average speed

= 5 5/6 mph , or

= 5.83 mph (to 2 decimals)

Step-by-step explanation:

Average speed is total distance divided by the total time it takes to cover the given distance.

Since uphill = 5 mph, and downhill = 7 mph, we know the average speed is between 5 and 7 mph.

Let

x = distance uphill, and also distance downhill.

Total distance = 2x miles

Total time = x/5 + x/7 hours = 12x/35 hours

Average speed

= total distance/total time

= 2x / (12x/35) mph

= 70x / 12x

= 5 5/6 mph

= 5.83 mph (to 2 decimals)

VERY IMPORTANT!! PLEASE HELPPP :(

Answer:

Step-by-step explanation:

Sigma notation means that you will add and continue adding using the function given. Furthermore, bottom number i = 1 is your starting point and the top number 3 is where you will stop the summation. So,

Let i = 1:

$4(\frac{1}{2}^{1-1})=4(1)=4$

Let i = 2

$4(\frac{1}{2}^{2-1})=4(\frac{1}{2})=\frac{4}{2}=2$

Let i = 3

$4(\frac{1}{2}^{3-1})= 4((\frac{1}{2})^2 )=4\frac{1}{4}=\frac{4}{4}=1$

And so let's add up our results:

4+2+1=7

All equations are identities, but not all identities are equations. <br> True or false

Elenna [48]

Answer:

Step-by-step explanation:

It is false that All equations are identities, but not all identities are equations, as all identities are equations, but only some equations are identities.

Identities are equations that are true no matter what the values are substituted for the variables present in the equation.

For example:

$8x=8x$ ,

$sinx=cos(x+\frac{\pi}{2})$ are all identities.

And $z=cosx+x^2$ is an equation, but is not an identity.

Hence, The given statement is false.
