Because 6 is greater than 0, so 0F would be colder.
Answer:
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.
For 12 Pounds (= 12 * 16 = 192 Ounce), it costs = 18.75
So, for 1 Ounce, it would be: 18.75 / 192 = 0.097
In short, Your Answer would be: $0.097
Hope this helps!
Answer:
Either- 200778.9263 or 81
Step-by-step explanation:
Type this into the calculator:
First: (1/9)^6= 1.881676423x10^-6
Then: 81^4= 43046721
Then multiply the two: (1.881676423x10^-6)x 43046721= 200778.9263
Or
Try this- type ((1/9)^6)x(81^4) into the calculator which comes out to 81
((1/9)^6)x(81^4)=81
Depends on which level you are at in math.
<span>The expression b^2-4ac is called the discriminant. If it is zero, or positive and a perfect square (like 4, 9, 25, 36, etc), the solutions to the quadratic equation will be rational numbers and factoring will work.
On the other hand, if the discriminant is positive but not a perfect square, the solutions will be irrational, and if it is negative, there are no real solutions. In either of those cases, the quadratic expression cannot be factored.
In the equation 2x^2+7x+3=0, the discriminant is b^2-4ac = 7^2 - 4*2*3= 49-24 = 25 = 5^2
That means that the solutions can be found by factoring.
