Twenty seven is b, not sure about the rest. we learn it different
(2y + 5)° = 4y °
- 4y + 2y° = -5°
-2y° = -5°
y =5/2
These look like displacement/distance questions
A. (DISTANCE) If Teddy went 8 feet underwater and 8 back to the surface he swam a total of 16 feet.
B. (DISPLACEMENT) They are looking at the final position compared to the initial position for this one. If you go 1.5 miles west and then 1.5 miles east, you're right back to where you started. So 0 miles away from the house. They do not want total distance travelled they want displacement.
C. (DISTANCE) You start at -50 feet (vertically, compared to sea level I'm guessing) and end up at 50 feet above vertically so you travelled a distance of 100 feet.
D. (DISTANCE) The change from -3 degrees to 3 degrees is 6 degrees.
Step-by-step explanation:
<u>Step 1: List out all of the formulas for the trigonometric functions
</u>
<em>sin(x) </em>= opposite/hypotenuse
<em>cos(x) </em>= adjacent/hypotenuse
<em>tan(x)</em> = opposite/adjacent
<u>Step 2: Find the value of h
</u>
cos(68) = 13/unknown is FALSE
cot(68) = 13/h is FALSE
sin(68) = h/unknown is FALSE
tan(68) = h/13 is TRUE
Answer: The correct option would be D
There is a lot of unnecessary information here made to trip you up.
1% of $150 is $1,50. If we add that to her purchase, we get $151.50
Provided she pays during the grace period, she should only have to pay $151.50
