If we look at our SOHCAHTOA rule:
cos(x) = adj/hyp
The adjacent side of N is 36, and the hypotenuse is 39.
Therefore:
cos(N) = 36 / 39
Answer: 1/8 of a mile
Step-by-step explanation: because 3/8 minus 1/4 is 1/8
Answer:
Starting with ΔABC, draw the dilation image of the triangle with a center at the origin and a scale factor of two. Notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). Dilations involve multiplication! Dilation with scale factor 2, multiply by 2.
We know that
the quadratic function in vertex form is--------------> y=a*(x-h)²+k
we have
f(x)=x²<span>+14x+40
y=</span>x²+14x+40
We can convert to vertex form by completing the
square on the right hand side
y-40=x²+14x
y-40-49=x²+14x-49------> subtract 49 on BOTH sides to
preserve the equality
y-40=(x²+14x+49)-49
y=(x²+14x+49)-49+40---------> y=(x+7)²-9
the answer is
the quadratic function in vertex form-----------> y=(x+7)²-9
<span>the vertex is the point (-7,-9)
