Answer: 1214\text{ in.}^2

Step-by-step explanation:

Given: Height of cylinder = 12.8 in.

The radius of the cylinder = 15.1 in.

We know that the lateral surface area of a cylinder is given by :-

LA=2\pi r h

Now, the lateral surface area of the given cylinder is given by :-

LA=2(3.14)(15.1)(12.8)\\\\\Rightarrow\ LA=1213.7984\approx1214\text{ in.}^2

Hence, she need 1214\text{ in.}^2 of fabric for this project.

What is the domain of the function H(w)=70/w
Ket [755]
The domain of the function given above is the value of w that would make it reasonable. Among the numbers, w cannot be zero because that would make the fraction 70/0 undefined. So the domain of the function is from negative infinity to positive infinity but not zero.

Write the slope-intercept form of the equation of the line through the given points.
9966 [12]

Answer:

y = 7x +2

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (0, 2 ) and (x₂, y₂ ) = (- 1, - 5 )

m = \frac{-5-2}{-1-0} = \frac{-7}{-1} = 7

the line crosses the y- axis at (0, 2 ) ⇒ c = 2

y = 7x + 2 ← equation of line
