This is an arithmetic sequence (graph is a line), so function:
a(n) = First term + (n-1) * Common Difference
Here First term = 42 and Common difference = 34 - 36 = -2 so
Answer B.
Answer:
$25 and 8 cents more
Step-by-step explanation:
55.50 - 30.50 = 25
18 - 10 = 8
Sin Ф=opposite/ hypotenuse
In this case:
sin 25º=9 in /c
c=9 in/ sin 25º
c≈21.3 in.
Answer: sin (25º), in this case can be used to find the lenght of the hypotenuse, and the length of this hypotenuse would be 21.3 in.
Answer:
Step-by-step explanation:
Triangle A
Use Pythagorean theorem.
x² + 12² = 13²
x² + 144 = 169
x² = 169 - 144
x² = 25
x = √25
x = 5 cm
Triangle B:
y² = 12² + 5²
= 144+ 25
= 169
y = √169
y = 13
