Answer:
sin22°
Step-by-step explanation:
Using the cofunction identity
cos x = sin (90 - x), then
cos68° = sin(90 - 68)° = sin22°
Answer:
Step-by-step explanation:
Part A
2x-3y =21 in slope-intercept form is y=2/3x-7 one you graph the equation it would be a parallel to the equation shown above so there are no intersections
PART B
y=1/3x^2 and y= 2/3x - 5
1/3x^2 = 2/3x-5
1/3x^2=2/3x-5
then u multiply everything by 3
1/3x^2*3 =2/3x *3-5*3
the three for 1/3*3 cancels out so you are left with
1x^2= 2x -15
1x^2-2x+15=0
You can not factor it and well i guess there is no intersection
im sorry if i got this wrong bc i had a similar question just different numbers and i tried to solve this one the way i sloved mine so im not sure of my answer for part b
Answer:
give the other peeson brainliest cuz y not
Step-by-step explanation:
Answer:
4/15 cocoa would be left if we made cookies
Step-by-step explanation:
4/6- 2/5
= 4(5)- 2(6)/30
= 20-12/30
=8/30
=4/15
