Answer:

188.5cm^2

Step-by-step explanation:

The surface area of a cylinder can be found using the equation: A=2\pi rh+2\pi r2.

When we plug in to this equation we get 2\pi (3)(7) + 2\pi(3^2) which equals 188.4955 which can be rounded up to 188.5cm^2

8 m minus 6 less or equal than 10
Studentka2010 [4]

Hi there! :)

Answer:

\huge\boxed{m\leq 2}

Equation:

8m - 6 ≤ 10

Add 6 to both sides:

8m ≤ 16

Divide both sides by 8:

8m/8 ≤ 16/8

m ≤ 2

Find the center, vertices, and foci of the ellipse with equation x squared divided by 400 plus y squared divided by 625 = 1
Inessa05 [86]

Answer:

x^2/400 + x^2/625

(x-0)^2/400) +(y-0^2/625)

x^2=400

X=sqrt. 400

x = 20

y^2=625

y = sqrt. 625

y= 25

a^2-c^2=b^2

sqrt 400-625 = c

20-25=c

The correct answer is c=-5

(-5,0)

What sine function represents an amplitude of 1, a period of 2pi, a horizontal shift of our, and a vertical shift of -4
alexandr1967 [171]

ANSWER

g(x) =  \sin(x  +4)  - 4

EXPLANATION

The basic sine function is

f(x) =  \sin(x)

The transformed sine function has equation

g(x) = a \sin(bx  +c )  + d

where a=1 is the amplitude

2π/b=2π is the period

c/b= 4 is the horizontal shift 4 units left.

d=-4 is a downward vertical shift of 4 units.

The required sine function is:

g(x) =  \sin(x  +4)  - 4
