So you have a right angle triangle. You need to use trig for this, as you have two values you can figure out a third.
You know that you have
90 deg. angle
19 deg. angle
Therefor you have 71 deg. angle
sin19 = x/15
15sin19 = x
x = 2.2
Now do Pythagoras c^2-b^2=a^2
a = 14.8
So the sides are 2.2 and 14.8 units long. (If these numbers are wrong tell me and I'll edit answer)
I’m not sure what the gate has to do with the problem, but you should just divide 780 by 120 to get 6.5. In other words, each foot costs $6.50.
it was 50 mph hope this helps
Answer:
D. Graph D
Step-by-step explanation:D. Graph D
Step-by-step explanation:
We know that, 'Direct Variation or Directly Proportional' is relationship between two variables where one is a constant multiple of the other.
That is, if one variable changes, the other variable also changes in proportion to the first variable.
The general form of 'Direct Variation' is y = kx, where k is a constant i.e. it does not have a y-intercept.
Now, according to our options, we see that the figures of A,B,C are the graphs of the straight lines given by y =-2x+2 , y=2x+2, y=-2x+2 respectively.
Each of these three equations have y-intercept, therefore cannot be the equations of a direct proportion.
Now, in option D, the figure is the graph of straight line y = -x and has no y-intercept.
Hence, the linear function in Graph D shows a direct proportion.
Answer:
The answer is (30, 109)
Step-by-step explanation:
In this problem we need to find the intersection point between the lines
y = 4x-11
and
y = 3.2x+13
We can easily solve this problem by plotting both lines in a graphing calculator and finding the intersection point.
Please see attached picture.
The answer is (30, 109)
