Step-by-step explanation:
<h3>(a)</h3>
The nearest squares to 220 are 14² = 196 and 15² = 225. Since 220 is closer to 225 than to 196, the nearest whole number to the square root of 220 is 15.
The square root of -220 is imaginary, so the nearest whole number value will be 15i.
__
<h3>(b)</h3>
The decimal fraction part of the root can be estimated from the nearest squares to be ...
(220 -196)/(225 -196) ≈ 0.828
Then the root of 220 to the nearest tenth is 14.8. The root of -220 to the nearest tenth will be the imaginary number 14.8i.
The price of each comb is $0.5, and the total income from selling x plastic combs is y = x/2
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more number and variables.
The linear equation y = x/2 models the income, in dollars, from selling x plastic combs. Hence:
Price of each comb = (x/2) / x = 0.5
The price of each comb is $0.5, and the total income from selling x plastic combs is y = x/2
