CAN SOMEBODY PLEASE HELP ME I AM SO CONFUSEDD

Answers

Answer 1

Answer: The formula for the surface area of a cylinder is 2πrh+2πr². R is the radius and h is the height.

2πrh+2πr²
2(3.14)(1.3)(4.8)+2(3.14)(1.3)²
39.19+10.61
=49.8

I hope this helped.

Howdy! Id love to have these questions answered asap! Thank you for the help! 1) Which angle is not coterminal to 120 degrees?
A. 840
B. -180
C. 480

2) Use the unit circle and the reference angle to determine which of the following trigonometric values is correct when theta = -90
A. Cos theta = undefined
B. Sin theta = -1
C. Tan = 0

Answers

Answer:

1. B.

2. B.

Step-by-step explanation:

Trigonometry

1) Coterminal angles can be found by adding or subtracting 360° (or 2\pi radians) to a given angle. If we have 120°, adding 360° gives 480°, adding again 360° gives 840°. There is no way to get -180°, so this option is not a coterminal angle to 120°

A. $Cos (-90^o)=0$ , and not undefined

B. $Sin (-90^o)=-1$ . This is correct

C. $Tan (-90^o)$ is undefined, not zero

Thus the only correct option is B.

What are the vertex and x-intercepts of the graph of the function below? y =(x + 4)(x - 2)

Answers

y = (x + 4)(x - 2)

The x-intercepts:

0 = x + 4
0 = x - 2

x = -4
x = 2

The vertex:

y = (x + 4)(x - 2)
y = x^2 + 2x - 8
x = -b/2a
If ax^2 + bx + c, then:
a = 1
b = 2
c - 8
x -2/2(1)
x = -1
y = (-1)^2 + 2(-1) - 8
y = -9

The vertex is (-1, -9)
The x-intercepts are -4 and 2

Answer: vertex: (1,-9); intercepts: x=4,-2

Solve for X:
-2(x+2) < 14

Answers

Answer:

x >-9

Step-by-step explanation:

-2 ( x + 2 ) < 14

Step 1 :- Distribute -2 .

-2x -4 < 14.

Step 2 :- Move constant to the right-hand side and change their sign . And flip the inequality sign.

-2x > 14 + 4

Step 3 :- Add 14 and 4.

-2x > 18

Step 4 :- Divide both side by -2.

-2x / - 2 > 18 / -2

x = -9

Answer:

I think the correct answer is

X<-9
