Answer:
2a^(5/2) - 4/a^(1/2)
Step-by-step explanation:
√a (2a^2 - 4/a)
= a^(1/2) (2a^2 - 4/a)
= 2a^(1/2 + 2) - 4a^(1/2 - 1)
= 2a^(5/2) - 4a^(-1/2)
= 2a^(5/2) - 4/a^(1/2)
Given data:
The given distance is d=26 km.
We know 1 kilometer is equal to approx 0.621 miles.
1km= 0.621 miles
Multiply the above expression with 26 on both sides.
26(1 km)= 26(0.621 miles)
26 km= 16.146 miles.
Thus, 26 kilometer is equal to 16.146 miles
Answer:
∠DEK = 88°
Step-by-step explanation:
Well, I supposed that ∠DEF is equal to ∠KEF and that the sum of these angles equals 88°
44° + 44° = 88°
Answer:
25% or 1:4
Step-by-step explanation:
When it says 1 in 4, that can be expressed as a 25% chance or as a ratio of 1:4. Since you are taking 4 people at random, and the chance is one in four, you have a 1/4th chance, therefore a 25% chance or a 1:4.
