1. A hotel is in the shape of a cylinder, with a circular foundation. The circumference of the foundation is 2 times the radiu

AysviL [449]

2)The circumference or perimeter of a circle with radius $r$ is

$P=2\pi r$ . Given $P=28\pi$ . Therefore,

$2\pi r =28\pi \\ r=14\\ d=2r=28\\ A=\pi r^2 \\ A=\pi (14)^2\\ A=[tex] 196\pi$

Thus the radius is $14\;ft$ , diameter $28\;ft$ and area $196\pi \;ft^2$

Which equation describes the function? Will give brainliest

Natalija [7]

Answer:

$y = - \frac{7}{3} x + 4$

Step-by-step explanation:

I'm going to use the process of elimination to get rid of the equations. The equation for slope is y=mx+b with b being the y-intercept. As you can see the y-intercept in this graph is 4 which removes the third equation as a possible answer. The slope is moving from left to right in a downwards direction which means it is a negative slope. The only answer with a negative slope is b therfore it is your answer.
