How do you do this type of exponent? Problem: x • x • x • x • ... • x ; I really don't get this and need help! Thanks.

To do this problem all you need to do is multiply the x's together and you would just add the x together by exponents Ex: x•x•x•x•x=? The answer would be x^5 Since I don't know how many x you have I can't give you the exact answer

You travel 3 miles downstream in a kayak at a speed of r miles per hour. You turn around and travel 4 miles upstream at a speed

shtirl [24]

<h3>Write a model in simplified form for the total time t (in hours) of the trip:</h3>

$Total\ time\ taken = \frac{3}{r} + \frac{4}{0.5r} + \frac{1}{r+1}\\$

<h3>It takes 2.95 hours when r is 4 miles per hour</h3>

<em><u>Solution</u></em>:

Given that,

<h3>You travel 3 miles downstream in a kayak at a speed of r miles per hour</h3>

Downstream:

Speed = r miles per hour

Distance = 3 miles

Time taken is given as:

$Downstream\ time = \frac{distance}{speed}\\\\Downstream\ time = \frac{3}{r} ------- eqn\ 1$

<h3>You turn around and travel 4 miles upstream at a speed of 0.5r miles per hour</h3>

Upstream:

Speed = 0.5r miles per hour

Distance = 4 miles

Therefore,

$Upstream\ time = \frac{4}{0.5r} -------- eqn 2$

<h3>Finally, you turn around and return to your original starting point at a speed of r + 1 miles per hour</h3>

Therefore,

$time = \frac{1}{r+1} ----------- eqn\ 3$

<em><u>a)Write a model in simplified form for the total time t (in hours) of the trip</u></em>

The total time taken is:

eqn 1 + eqn 2 + eqn 3

$Total\ time\ taken = \frac{3}{r} + \frac{4}{0.5r} + \frac{1}{r+1}\\$

<em><u>b)How long does your trip take when r is 4 miles per hour?</u></em>

Substitute r = 4

$Total\ time\ taken = \frac{3}{4} + \frac{4}{0.5 \times 4} + \frac{1}{4+1}\\\\Total\ time\ taken = 0.75 + 2 + 0.2\\\\Total\ time\ taken = 2.95$

Thus it takes 2.95 hours when r is 4 miles per hour

Len is baking a square cake for his friend wedding. When served to the guests, the cake will be cut into square pieces 1 inch on

jonny [76]

You would just need to take the square root of 121 since it is square. So:

√121= 11 inches per side

NOT THE SAME 1 FROM BEFORE

masha68 [24]

Answer:

B. 40 ≤ e ≤ 100

Step-by-step explanation:

In a function, the domain values are the independent variables, and are always plotted on the x-axis, while the range values the dependent variables, which are always plotted on the y-axis on a graph.

From the graph given, it shows that f is a function of e. Which is, $e(f)$ .

Therefore, the range of the function would be: B. 40 ≤ e ≤ 100
