Answer:

A

Step-by-step explanation:

We can convert a repeating decimal into a fraction by multiplying by elimination using a value that is 1000 times the value we are solving for.

$1000x=5646.646464... \\x=5.646464... \\ 999x=5641 \\ x=\frac{5641}{999} \\ x=5\frac{645}{999}$

<em>Answer: C</em>

<em />

<em />

<em>It is C because when there is a line at the top of the number, it is infinite and repeats many times. That number in a shorter was can be written as a fraction over 990. Two of the answer choices has 990 in it which is letters B and C. This eliminates answer choices A and D. The number that is within the dot is your numerator (645) and 990 is your denominator. Overall the answer is 645/990</em>

The point P( 0.5 , 10 ) lies on the curve y = 5 / x . Let Q be the point (x, 5 / x ) . a.) Find the slope of the secant line PQ

zalisa [80]

Answer:

Based on the results it is expected that the slope of the tangent line at the point (0.5,10) is -20.

Step-by-step explanation:

To see that compute, the slopes for the given points as follows:

1. For $x=0.6$ we have:

$m=\dfrac{(5/0.6)-10}{0.6-0.5}=-16.66$

2. For $x=0.51$ we have:

$m=\dfrac{(5/0.51)-10}{0.51-0.5}=-19.60$

3. For $x=0.4$ we have:

$m=\dfrac{(5/0.4)-10}{0.4-0.5}=-25.00$

4. For $x=0.49$ we have:

$m=\dfrac{(5/0.49)-10}{0.49-0.5}=-20.40$

So, we observe that the slope of the tangent line at $(0.5, 10)$ is close to the value -20.

The graph shown below is useful to see the secant lines that approximates the tangent line.

A fish store can place 5 fish in each fish bowl. If there are 263 fish to place, how many fish bowls are needed for all 263 fish

skad [1K]

Answer:

Step-by-step explanation:

1 bowl holds 5 fish

x bowls hold 263 fish

1/x = 5/263 Cross multiply

5x = 263 Divide by 5

5x/5 = 263/5

x = 52.6

So you actually need 53 fishbowls. One of them holds only 3 fish
