Answer:

40/10  [4 meters/sec]

Step-by-step explanation:

Watch for what the units are telling us.  The number that is being requested  

is speed in units of meters/sec.  We are given 40 meters and 10 seconds.  If we divide 40 meters by 10 seconds (10 meters/10 seconds), we get 4 meters/sec, the correct dimension.

Find an equation of the circle that satisfies the given conditions. (Give your answer in terms of x and y.)
masya89 [10]

Answer:

(x-4)^2+(y+5)^2=90

Step-by-step explanation:

The equation of a circle of radius r, centered at the point (a,b) is

(x-a)^2+(y-b)^2=r^2

We already know the center is at (4,-5), we are just missing the radius. To find the radius, we can use the fact that the circle passes through the point (7,4), and so the radius is just the distance from the center to this point (see attached image). So we find the distance by using distance formula between the points (7,4) and (4,-5):

radius=\sqrt{(7-4)^2+(4-(-5))^2}=\sqrt{3^2+9^2}=\sqrt{90}

And now that we know the radius, we can write the equation of the circle:

(x-4)^2+(y-(-5))^2=\sqrt{90}^2

(x-4)^2+(y+5)^2=90

A function is created to represent the costs of living per person in the family. What restrictions would be made to the domain?
Nitella [24]

Let

x-------> the number of persons in the family

f(x)------> the function represent the cost of living

we know that

The domain of the function  would only include positive integers, because the number of persons can not be negative or a fraction

The range of the function would only include positive numbers, because the cost can not be negative

therefore

<u>the answer is the option B</u>

The domain would only include positive integers.
