Answer:
(<em>x</em>, <em>y</em>) represent coordinates, <em>m</em> represents slope, and <em>b</em> represents the y-intercept
Your answer would be 64 in².
To find the surface area, you just need to find the area of each of the shapes shown and add them together.
We can find the area of one of the triangles by doing:
(base × height)/2
(6 × 4)/2 = 24/2 = 12
As there are 4 identical triangles, the area of all of them would be 12 × 4 = 48 in².
Now we need to find the area of the square in the middle, which would be 4 × 4 = 16 in².
Adding these together gives us 16 + 48 = 64 in²
I hope this helps!
It would be helpful if a figure is drawn as you can see clearly the situation of the problem. We would see that a right triangle is made where the angle between the elevation of the airplane with respect to the ground is 7 degrees and the horizontal distance is the base of the triangle. We use trigonemetric functions.
tan 7 = opposite side / adjacent = height / 3729
height = 458 meters
Answer:
3
Step-by-step explanation:
Plug in the values for a and b= -7(-1)-2(2)
Multiply= 7-4
Subtract= 3
Hope this helps ^-^
