The slope would be letter b
Secd(38)
= 1/cosd(38)
= 1/sqrt[1-sind^2(38)] because cos^2(x) + sin^2(x) = 1
cos(30) = sqrt(3)/2 = 0.8660
cos(45) = 0.707
so cos(38) can be assumed to some where around 0.8
= 1/0.8
= 1.25
Therefore D is correct answer
Answer:
200.131234
Step-by-step explanation:
For this case we have that the variable "k" represents the floor area of Melanie's kitchen.
We have that the floor area of the room is 1.5 times the floor area of the kitchen, then, we propose the following function to find the floor area of the room:
Answer:
Option A and D
Answer:
x = -3.5
Step-by-step explanation:
Simplifying
0.4x + 2.9 = 1.5
Reorder the terms:
2.9 + 0.4x = 1.5
Solving
2.9 + 0.4x = 1.5
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2.9' to each side of the equation.
2.9 + -2.9 + 0.4x = 1.5 + -2.9
Combine like terms: 2.9 + -2.9 = 0.0
0.0 + 0.4x = 1.5 + -2.9
0.4x = 1.5 + -2.9
Combine like terms: 1.5 + -2.9 = -1.4
0.4x = -1.4
Divide each side by '0.4'.
x = -3.5
Simplifying
x = -3.5
