Answer:
hi, hope you are good!, hope you have the greatst holidays ever!
Step-by-step explanation:
The rate(speed) is 1 3/5
We can use the distance formula to solve:
d= rt
D= 4/5
T=1/2 hr
Substitute
4/5= 1/2t
Multiply 2 on both sides
2* (4/5)=(1/2)t * 2
8/5=t
We can simplify this to 1 3/5
Answer:
(A) y = 24
Step-by-step explanation:
Given GDEF is a parallelogram and m∠E = 108°
To find: value of y
In ║grm GDEF,
m∠D + m∠E = 180° (Consecutive angles of parallelogram are supplementary)
3y° + 108° = 180°
3y° = 180° - 108°
3y° = 72°
y = 72°/3 = 24°
Therefore, option (A) is the correct answer.
Answer:
D
Step-by-step explanation:
To convert from polar to rectangular form
• x = rcosΘ , y = rsinΘ
• r = 
⇒ r² = x² + y²
Given
r = 8cosΘ
r = 8 × 
( multiply both sides by r )
r² = 8x, hence
x² + y² = 8x ⇒ D
