Answer:
cos (12+10) = cos (22)
Step-by-step explanation:
Cos 12* cos 10* - sin 12* sin 10*
Appling the trig identity: cos (a + b) = cos a.cos b - sin a.sin b
inputing the values of a and b
cos (12 + 10) = cos 12cos 10 - sin 12sin 10 = cos (22)
Photo math helps it worked for me so might help you :)
Answer:
Step-by-step explanation:
In this problem we have a horizontal ellipse, because the major axis is the x-axis
The equation of a horizontal ellipse is equal to
where
(h,k) is the center of the ellipse
a and b are the respective vertices distances from center
we have
vertices at (7, 0) and (-7, 0)
co-vertices at (0, 1) and (0, -1)
so
The center is the origin (0.0) (The center is the midpoint of the vertices)
a=7
b=1
substitute
Answer:
d= 292 sunny days
Step-by-step explanation:
d= represent the sunny days in each year in Yucca Manor.
how many days(d) is equal to(=), 80% of 365 days.
d= 0.80*365 <--- equation for the problem.
80% = .80 because percent means number divided by 100.
d= 292 sunny days are in each year in Yucca Manor.
