Step-by-step explanation:
Answer: ORP and ORN are a linear pair.
Answer: 6.28 feet
Step-by-step explanation:
Area of the lens= πr^2
Since area has been given as 3.14
3.14 = πr^2
Note that π = 3.14
3.14 = 3.14r^2
r^2 = 3.14/3.14
r^2 = 1
r = ✓1
r = 1
The radius of the lens is 1
Circumference of the lens= 2πr
= 2 × 3.14 × 1
= 6.28 feet
A)
y=2^x
4^x=2^(2x)=y²
solution:
y=2^x hence y²=4^x
chek:
x=5 ⇒ y=2⁵=32
4⁵=1024
y₂=32²=1024
b)
8(4^x)-9(2^x)+1=0
8(2^(2x)-9(2^x)+1=0
2^x=t
8t²-9t+1=0
We solve the quadratic.
t₁=1/8 ⇒2^x=1/8
2^x=1/2³
2^x=2⁻³
x=-3
t₂=1 ⇒ 2^x=1 ⇒x=0
Solutions:
x=-3
x=0
The interquartile range for Group A employees is 1 more than the interquartile range for Group B students.
