Answer:
(b) {yly = -9, -3, 0, 5, 7}
Step-by-step explanation:
The range is the set of y-values in the ordered pairs. It is usually convenient to list a set in alphanumeric order.
The second values of the ordered pairs are 0, -3, -9, 5, 7. So, the range is ...
y ∈ {-9, -3, 0, 5, 7} . . . . . matches the second choice
Answer:
The correct answer is area of the coffee shop sign and that is equal to 254.57 square inches.
Step-by-step explanation:
A coffee shop sign is in the shape of a circle.
The sign measures 18 inches across in diameter.
Thus the radius of the coffee sign is 9 inches.
We need to find the measurement that is closer to the measurement in square inches.
Thus invariably means we need to find the surface area of the coffee shop sign.
Area in square inches of the coffee sign is given by π ×
where r is the radius of the circle. Therefore area is π ×
= 81 π = 254.57 square inches.
Answer:
<u>Given function:</u>
<u>Current price is:</u>
- p(0) = 2500(1.041)^0 = $2500
<u>Price after 8 years:</u>
- p(8) = 2500(1.041)^8 = $3448 (rounded)
Answer:
The function's graphic is the one that is below the first one in th right.
Step-by-step explanation:
If we want to know how much Chelsea earns for dogsitting her neighbours' dogs, we have to form a linear equation, that must have the following formula:
![y= ax + b](https://tex.z-dn.net/?f=y%3D%20ax%20%2B%20b)
In this case, B is the constant value. We know Chelsea charges 12$ for dogsitting, and that doesn't depend on anything (B). But, if you want to Chelsea to walk your dog, then you'd to pay 2.50$ for each walk (X).
![y= 2.50x + 12](https://tex.z-dn.net/?f=y%3D%202.50x%20%2B%2012)
So, if Chelsea doesn't walk the neighbour's dog (x=0), she would be earning 12 dolars.
![y= 2.50 x 0 + 12 = 12](https://tex.z-dn.net/?f=y%3D%202.50%20x%200%20%2B%2012%20%3D%2012)
If she walks four times the dog, she would be earning:
![y= 2.50 x 4 + 12 = 10 + 12 = 22](https://tex.z-dn.net/?f=y%3D%202.50%20x%204%20%2B%2012%20%3D%2010%20%2B%2012%20%3D%2022%20)
Knowing these two values, we can graph the equation. When x=0, y=12, and when x=4, y=22
The function's graphic is the one that is remarked in the attachment.
