Hey there :)
We can solve 2 ways: With a calculator and Without
With:
√53 = 7.28
Therefore this lies between 7 and 8
Without:
6² and 7² = 36 and 49
Still, the values are less than 53, which means √53 does not lie between 6 and 7
7² and 8² = 49 and 64
53 is between both values, therefore √53 lies between 7 and 8
Your answer will be option B) 7 and 8
Answer:
22 - 34i
Step-by-step explanation:
note that i² = - 1
Given
(5 - 4i)(6 - 2i) ← expand factors using FOIL
= 30 - 10i - 24i + 8i²
= 30 - 10i - 24i - 8 ← collect like terms
22 - 34i
Answer:
5sqrt(5) meters
Step-by-step explanation:
Picture a right triangle with one horizontal leg and one vertical leg, as well as the hypotenuse. Walking 10 meters west is represented horizontally. Likewise, walking 5 meters south is represented vertically. This right triangle thus has two legs of lengths 10 m and 5 m respectively; according to the Pythagorean Theorem, the length of the diagonal (which represents the distance from home) is d = sqrt(10^2 + 5^2) = sqrt(125) = 5sqrt(5). Round this off to the nearest tenth m (meter or mile) after evaluating the square root on a calculator.
Answer:
Area of Trapezium=1/2h(L1+L2)
I think it will help you
To solve divide both sides by 4 to cancel out the 4 on the x side to get x alone. Then just do -10/4. That gives you 2.5 so (X=2.5). Hope I helped and have a great day and night
