The answer is cos70
the angles add up to 180, so 180 - 90 - 20 = 70 degrees.
Answer:
32 ; 20
Step-by-step explanation:
Middle section: 26
Sum of parallel lengths: 2 × 26 = 52
Ratio of the sides:
100% : 62.5%
8 : 5
5/(8+5) × 52
20
8/(8+5) × 52
32
Answer:
B
Step-by-step explanation:
We can use the standard form of an exponential function:
The point (0, 18) tells us that <em>y</em> = 18 when <em>x</em> = 0. Hence:
Simplify:
Our equation is now:
Next, the point (-1, 15) tells us that <em>y</em> = 15 when <em>x</em> = -1. Hence:
Isolate the variable:
Hence:
By substitution:
Our answer is B.
You just need to trace it without moving your pencil off the paper
