Cos(x) = 10.5 / 20
cos(x) = 0.525
answer
C.
x = 58.3"
Answer:
Step-by-step explanation:
Start by writing these five numbers in just one format (improper fractions with denominator 10):
9/5 = 18/10, and
-2.5 = -25/10, and
-1.1 = -11/10, and
-4/5 = -8/10, and, finally
0.8 = 8/10
The smallest of these (the least) is -25/10, and
the largest is 18/10.
Arranged in ascending order, we have:
-25/10, -11/10, -8/10, 8/10, 18/10, or
-2.5, -1.1, -4/5, 0.8, 9/5
Answer 5 because cos(60) x 10 = gives 5
Answer:
(x,y)=(-2,-5)
Step-by-step explanation:
y=1/2x-4
y=-2x-9
(y=) 1/2x-4=-2x-9
1/2x +2x=-9+4
1/2x +4/2x=-5
5/2x=-5
5x=-5*2
5x=-10
x=-2
x=-2
y=-2x-9=-2*(-2)-9=4-9=-5
(x,y)=(-2,-5)
