sin(t) = √15/4,
cos(t) = - 1/4,
tan(t) = - √15
Step-by-step explanation:
The coordinates of the terminal point P(x, y) determined by t are x = - 1/4, and y = √15/4;
sin(t) = y = √15/4
cos(t) = x = - 1/4
tan(t) = y/x = √15/4 / - 1/4 = - √15

I WILL MAKE YOU BRAINLEST AND I MADE IT WORTH 50 POINTS
Answers
explanation:
60 miles * 8 hours = 480 miles
75 miles * x hours = 480 miles
x hours = 480 miles / 75 miles
6.4 hours = 75 miles
Time taken with average speed of 75 mph is 6.4 hour.
Given that;
Time taken with average speed of 60 mph = 8 hour
Find:
Time taken with average speed of 75 mph
Computation:
Distance = Speed × Time
Total Distance = 60 × 8
Total Distance = 480 miles
Time taken with average speed of 75 mph = Total distance / Speed
Time taken with average speed of 75 mph = 480 / 75
Time taken with average speed of 75 mph = 6.4 hour

The total volume of the crayon is 4,650.2 mm³.
The total surface area of the crayon is 2,300.33 mm².
What is the volume and surface area of one crayon?The volume and surface area of one crayon is calculated by applying the following formula as follows;
The volume of the cylinder is calculated as;
V = πr²h
where;
r is the radius of the cylinder = 8.5 mm / 2 = 4.25 mmh is the height of the cylinderV = π x (4.25)² x (80)
V = 4539.6 mm³
The volume of the cone is calculated as;
V = ¹/₃ πr²h
V = ¹/₃ π(6.5/2)² x (10)
V = 110.6 mm³
Total volume of the crayon = 4539.6 mm³ + 110.6 mm³ = 4,650.2 mm³
The surface area of the cylindrical part of the crayon is calculated as;
S.A = 2πrh + πr²
S.A = 2π(4.25)(80) + π(4.25)²
S.A = 2,193.03 mm²
The surface area of the cone part of the crayon is calculated as;
S.A = πrs
where;
s is the slant heightr is the radius = 6.5 mm/2 = 3.25 mms = √ (10² + 3.25²)
s = 10.51 mm
S.A = π x 3.25 mm x 10.51 mm
S.A = 107.3 mm²
The total surface area of the crayon = 107.3 mm² + 2,193.03 mm² = 2,300.33 mm²
