Angle 1 is an angle of depression because you start off looking directly horizontal and you look down to aim at the ground
Angle 3 is an angle of elevation. You start looking horizontally and then you look up
<span>When you have an equation of the form y = mx + b (which you do in this case), the slope is always equal to the coefficient of x, which is m or 12 in this case. Since there is no "b" in your equation, you could say that b=0, and the line is known to cross the y axis at zero.
In case you are interested, if the equation said y = 12 x + 3 the slope of the line would still be 12 but the line would cross the y axis at 3. If the equation said y = 12x -4, the line would have a slope of 12 and would cross the y axis at -4.</span>
Answer:
C
Step-by-step explanation:
39*34= 1326 (the area of the full square
8*10=80 (the area of the small square that is cut off)
1326-80= 1246
Answer:
The rate of change is 0.08 and the initial value is 24.
Step-by-step explanation:
1. You have the following formula:
2. It has the form of a equation of the line, which is:
Where 
is the slope, which gives the rate of change and 
is the y-intercept (The initial value, when 
)
3. Therefore, the rate of change of the given formula is:
4. And the initial value is:
We can proceed in solving the problem since all information are given such as 2*4*5costheta.
we have a=4, b=5, and C=theta
let us solve for "c" using Pythagorean
c²=a²+b²
c²=4²+5²
c=6.4
Solving for theta or C
c²=a²+b²-2abcosC
6.4²=4²+5²-2*4*5*cosC
C=90
