The graph of r = -10 cos θ has which of the following characteristics?

Ronch [10]

Step-by-step explanation:

If we convert

$r = - 10 \cos(x)$

to a Cartesian equation,

${r}^{2} = - 10 r \: \cos(x)$

${x}^{2} + {y}^{2} = - 10x$

${x}^{2} + 10x + {y}^{2} = 0$

${x}^{2} + 10x + 25 + {y}^{2} = 25$

$(x + 5) {}^{2} + {y}^{2} = 25$

So we have a circle with center (-5,0), with a diameter of 10.

Emanuel surveyed a random sample of 505050 subscribers to Auto Wheel magazine about the number of cars that they own. Of the sub

Anna [14]

Answer:

The most reasonable estimate for the number of Auto Wheel magazine subscribers who own fewer than 2 is 102

Step-by-step explanation:

We can build an estimate from a sample, and this estimate will be the best estimate for the proportion of the population.

Sample:

50 subscribers

15 own fewer than 2 vehicles

Proportion:

15/50 = 0.3 = 30% own fewer than 2 vehicles.

Based on the data, what is the most reasonable estimate for the number of Auto Wheel magazine subscribers who own fewer than 2 vehicles?

340 subscribers

The most reasonable estimate for this number is 0.3*340.

0.3*340 = 102

The most reasonable estimate for the number of Auto Wheel magazine subscribers who own fewer than 2 is 102

For all real values of m,<br> 8 + 3(m - 5) =?

sineoko [7]

Answer:

We have the value as 3m-7

Step-by-step explanation:

It is given that we have the real number m. Now we are required to find the simplified form or the value of the expression: $8 + 3(m - 5)$

Thus we can write it as:

$8 + 3(m - 5)\\=8 + 3m-3\cdot \:5$

Here we have to use the property:

$a\left(b-c\right)=ab-ac$

So now we have:

$8 + 3m-3\cdot \:5\\=8+3m-15\\=3m-7$

So this is the required final value of the expression.
