Answer: a) 6700 b) 2233
Step-by-step explanation:
a)
b)
(-4,8)(6,13)
slope(m) = (13 - 8) / (6 - (-4) = 5 / (6 + 4) = 5/10 = 1/2
y = mx + b
slope(m) = 1/2
use either of ur points (6,13)...x = 6 and y = 13
now sub and find b, the y int
13 = 1/2(6) + b
13 = 3 + b
13 - 3 = b
10 = b
so ur equation is : y = 1/2x + 10 (slope intercept form)
or..
y = 1/2x + 10
-1/2x + y = 10...multiply by -2
x - 2y = -20 (standard form)
answer :
<em>Front & back</em>
explanation :
<em>Area = lw </em>
<em> ( length x width ) </em>
<em></em>
<em>CORRECT </em>
<em>Front: 4 x 7 = 28 </em>
<em>Back: 4 x 7 = 28</em>
<em></em>
<em>INCORRECT </em>
<em>Bottom: 7 x 9 = 63 </em>
<em>Top: 7 x 9 = 63</em>
<em>Right: 4 x 9 = 36</em>
<em>Left: 4 x 9 = 36 </em>
That would be 75t
If t = 1
75(1) = 75 miles traveled in 1 hour which is correct if it is moving at 75 miles per hour
Answer:
x = 2.74cm

As we know from the last post that we'll be using cosine.
This will be the rearranged formula :
(Side) Cos ( Angle) = Side
8 × Cos (70) = 2.73616....cm
