Answer from: Quest

this question relies purely on our observation of the graph and a knowledge of the behaviour of a graph of a hyperbola.

now, what we should realise is that there are two asymptotes - one at x = 0 and one at y = 0. what this means is that the graph will gradually approach, but never touch, these two lines. so, as x becomes more positive (ie. 'a very large positive number'), it will get closer to the line y = 0 (ie. the x-axis) - which means that the value of f(x) will gradually become smaller and closer to 0 - but will never reach it.

we can also observe this from the right half of the graph, where the graph gradually lowers closer and closer to the x-axis as x increases. what is important to note however is that it will never actually touch the x-axis (ie. f(x) will not equal 0) since there is an asymptote there. given this, we can see that option d, f(x) is a very small positive number, would be correct.

answer

$25\pi {ft}^{2}$

explanation

the area of a circle is calculated using the formula

$area =\pi {r}^{2}$

$area = \frac{\pi \: {d}^{2} }{4}$

we can use any of the above formulae to calculate the required. preferably, let us use the latter since the diameter is

$d = 10ft$

we substitute the diameter into the formula to get:

$area = \frac{\pi \: \times {10}^{2} }{4}$

$area = \frac{100\pi}{4}$

$area = 25\pi {ft}^{2}$

this is the exact value for the area of the circle.

the correct answer is a

1. 25pi ft^2 2. 5pi ft^2 3. 10pi ft^2 3. 20pi ft^2

Answer from: Quest

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )

Which inequality is represented by the graph? (0,1) (6,0)

Answer from: Quest

answer: solve 5\cdot 2^x=2405⋅2

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}

5⋅2

=240

=48
