Answer:
Step-by-step explanation:
A.
(7^2)^x = 1
(49)^x = 1
thus x = 0
B.
(7^0)^x=1
(1)^x = 1
x can be any real number.
Answer:
1) Option (b) 32km
2) Option (c) 17
Step-by-step explanation:
According to Pythagoras Theorem,
Hypotenuse²=Perpendicular²+Base²
H²=P²+B²
1) Perpendicular=?
Base=24km
Hypotenuse=40km
40²=P²+24²
1600=P²+576
1600-576=P²
1024=P²
√1024=P
32=P
2) Perpendicular=15
Base=8
Hypotenuse=?
H²=15²+8²
H²=225+64
H²=289
H=√289
H=17
Answer:
15 and 20
Step-by-step explanation:
When dividing 88 by 5 we wil have;
88/5
= 17 3/5
= 17 + 0.6
= 17.6
So we are to find the two numbers that 17.6 falls in between
From the given option 17.6 falls between 15 and 20. Hence the required numbers are 15 and 20
