34-12=22
the answer is:
If the outside is 34c and the inside is 12c then the answer is 22c, as you are taking off 12 from 34.
Answer:
If the value of a is negative the line is decreasing.
Step-by-step explanation:
The value of a, the coefficient of x, is the slope.
If the slope is positive, the line is increasing from left to right.
If the slope is negative, the line is decreasing from left to right.
Answer:
the submarine is 92.994 feet ≈ 93 feet deep from the surface of the water
Step-by-step explanation:
We can think in a triangle where the hypotenuse is the detection distance and the angle with the horizontal surface of water is the depression angle, then the underwater distance is the vertical side of the triangle.
If we denote Ф as the angle of depression ,d as the detection distance and x as the unknown depth of the submarine, using trigonometry:
x = d* sin Ф
thus
x= d * sin Ф = 238 feet * sin 23° = 92.994 feet ≈ 93 feet
Answer:
a) 
The graph is on the figure with the red line
b) 
And the equation would be:
The graph is on the figure with the blue line
Step-by-step explanation:
Part a
We know that a=2 and b =1
The general expression is given by:
The graph is on the figure with the red line
Part b
For this case we know that a=3 and we know a point given (2,2). Then we can find the value of b like this:
And the equation would be:
The graph is on the figure with the blue line
