Answer:
38.5
Step-by-step explanation:
1.)use BEDMAS rule so multiply first
10 × 2.5 + 13.5
=25 + 13.5
2.) then add
= 25 + 13.5

Answer:
y₂ = 3
Step-by-step explanation:
Calculate the slope m using the slope formula and equate to - 
m = 
with (x₁, y₁ ) = (7, - 6) and (x₂, y₂ ) = (- 5, y₂ )
m =
, that is
= -
( cross- multiply )
4(y₂ + 6) = 36 ( divide both sides by 4 )
y₂ + 6 = 9 ( subtract 6 from both sides )
y₂ = 3
Answer:
A. Figure A
Step-by-step explanation:
The protractor on the top left has an arrow halfway inbetween 50° and 60, making the angle 55°.
Therefore, the answer is Figure A.
Frequency = 1/period
Frequency = 1 / 0.001136
Frequency = 880.2816 Hz
Rounded to the nearest frequency = 880 Hz
