Answer:
A. The "9" in the second number represents 10 times as much as the "9" in the first number.
Step-by-step explanation:
If you look at the "9" in the first number as 90 and multiply that by 10, you will get 900. In the second number, the "9" is in the 100's place.
59 is a tough bird to deal with; its only factors are 1 and 59.
Thus, forget about factoring. Instead, use the quadratic formula, or solve the equation by completing the square.
Please note: x2 is ambiguous. Please write x^2 to indicate "the square of 2."
Here you have 1x^2 - 12x + 59 = 0, for which a=1, b=-12 and c=59.
Use the quadratic formula: x=[-b plus or minus sqrt(b^2-4ac)] / (2a)
to find the two roots. Notice that the "discriminant" b^2 - 4ac will be negative, meaning that your two roots will be "complex."
Answer:
Remember that logarithms are inverse of exponentials. That means the result of the logarithm is equal to the exponent of a power with the same base.
<h3>1. (a)</h3>
Notice that the result is one beacuse 
<h3>(b)</h3>
Because 
<h3>(c)</h3>
So, 
<h3>2. </h3>
I would say to thim that 
and 
are variables of the logarithm, which be solved by imagine the logarithm as an exponential like
In other words, the is the exponent and the is the result of the exponential.
The total number of people that all the cars can hold is greater than 480 and less than 500 people.
A: According to the given situation, where both the number of trolley cars and the number of people in each car must have two digits and be less than 30.
Hence, the possible number of trolley cars in the park = 22 and a possible number of people in each car= 22
B: explain how you found your answer.
Lets suppose the number of cars be =c and the number of persons be= p
As the number of cars and number of person are same, so c=p
so, 
should lie the given range of 480 to 500.
Now, the nearest perfect square that lies between 480 and 500 is 484.
The square root of 484 is 22. So, the number of cars and people are 22.
C: This is the only hit and trial method for solving this question.
Answer:
the opposite of the opposite of -9, the opposite of 6, the opposite of 4, the opposite of 0, the opposite of the opposite of 7
Explanation:
the opposite of 4 = -4
the opposite of the opposite of -9 = -9
the opposite of 6 = -6
the opposite of the opposite of 7 = 7
the opposite of 0 = 0
Then you just put them in order.
Hope this helps!
