Find a cofunction with the same value as the given expression. csc 52°A. sec 52°
B. sec 38°
C. sin 52°
D. sec 142°

Answers

Answer 1
Answer: To find a cofunction with the same value as the expression csc 52*, you would use the formula like this.  csc (x) = sec (90-x). So if you use csc(52) that equals sec(90-52). This in turn, equals sec(38). So the answer is B.

Answers

this can be solved with an equation.

4x+2y< 12 

now, as far as I can tell this question was made multiple choice for a reason; just start to plug in numbers. So using the answers x is either equal to 1 or 2. lets try and solve the equation plugging 2 in. When you solve for this you end up with y<2 none of your answers have one where y<2 so x must be 1. so lets solve for x=1.
you end up getting  y<4

The only answer where x=1 and y<4 is C sos c is your answer. Hope this helped! :)

Justify each step in solving the equation  by writing a reason for each statement.

Answers

Step-by-step explanation:

We are provided with an equation and are required to give reasons on how we got the final answer.

(1.) The equation is -3(2x-3) = 25-8x is given.

(2.) In this step, we have simplified the left hand side of the equation by opening the bracket i.e. -6x+9 = 25-8x

(3.) Here, the terms containing 'x' are brought to the left hand side of the equation and simplified i.e. 2x+9 = 25

(4.) Now, the constant terms of the equation are brought to the right side of the equation and simplified i.e. 2x = 16.

(5.) Lastly, the whole equation is divided by 2 in order to get the value of 'x' i.e. x = 8.

One question is all I need help on.

The lateral area of a cube is 36 square inches. How long is each edge?

Answers

The length of the edge of the given cube that has a lateral area of 36 square inches is: 3 inches.

What is the Lateral Area of a Cube?

Lateral area of a cube = 4a², wherea is the length of each edge of the cube.

Given the parameters:

  • Lateral area = 36 square inches
  • Length of each edge = a = ?

4a² = 36

a² = 36/4

a² = 9

a = 3 inches.

Length of each edge of the cube = 3 inches.

#SPJ2
Cubes have three square sides. The area of one side is the edge length squared:
36 = L^2
L = sqrt(36) = 6
The volume of a cube is edge length cubed:
V = L^3 = 216 cubic inches
