3-1=2 and 5-7=-2, so the whole thing simplified is 2y-2x+3
Answer:
The value of sin X = 12 / 13
Step-by-step explanation:
Given
- The side opposite to angle ∠X = 12
To determine
sin X = ?
We know that the trigonometric ratio involving sin Ф such as
sin Ф = opposite / hypotenuse
Here:
- The side opposite of Angle X = 12
so substituting Ф = X, opposite = 12 and hypotenuse = 13 in the equation
sin Ф = opposite / hypotenuse
sin X = 12 / 13
Therefore, the value of sin X = 12 / 13
Answer:
Density = 52.8 pound per cubic feet.
Step-by-step explanation:
Given the following data;
Length = 2.5 feet
Width = 0.5 feet
Height = 0.25 feet
Mass = 16.5 pound
To find the density of the wood;
First of all, we would determine the volume of the wood.
Volume = length * width * height
Volume = 2.5 * 0.5 * 0.25
Volume = 0.3125 cubic feet
Next, we find the density;
Mathematically, density is given by the formula;
Density = mass/volume
Substituting into the formula, we have;
Density = 16.5/0.3125
Density = 52.8 pound per cubic feet.
Your answer would be 2fg. This is the exact value.
