Answer/Step-by-step explanation:
✔️Find BC:
Reference angle = 50°
Opposite = BC
Adjacent = 5 cm
Based on trigonometric ratio, thus:
Tan 50 = BC/5
Multiply both sides by 5
BC = 5 × tan 50
BC = 5.96 cm (to 3 s.f)
✔️Find x:
Reference angle = 38°
Opp = x
Adj = BC = 5.96 cm
Based in trigonometric ratio, thus:
Tan 38 = x/5.96
Multiply both sides by 5.96
x = 5.96 × tan 38
X = 4.66 (3 s.f)
Answer: 10(2)=20 and 4(3)=12
Step-by-step explanation:
1) Divide 20 by 2 which would be 10 that gives you the sum of F
2) Divide 12 by 3 which is equals 4 so thats the sum of F for f(3)=12
Answer:

Step-by-step explanation:
we know that
The volume of a cylinder (sculpture) is equal to

In this problem we have
----> the radius is half the diameter

substitute the values

Y=mx+b where m=slope which is change in y divided by change in x m=(-8-7)/(4-9)=-15/-5=3 so we have y=3x+b now we can use either point, I'll use (9,7), to solve for b or the y-intercept... 7=3(9)+b 7=27+b b=-20so our line is: y=3x-20
