9th grade math I don’t understand

Mathematics
1 answer:
Tema [17]3 years ago

Answer:

434

Step-by-step explanation:

Looking at this sequence, we can immediately tell that it is <em>arithmetic</em>, because the terms keep adding up by 9.

Now that we know it is arithmetic, we can use the formula:

t_{n} = t_{1} + (n-1)d

Where tn represents the nth number, t1 represents the first term, and d represents the increasing change.

Plugging in the given values, we have:

t_{48}= 11+(48-1)9\\t_{48}=11+47*9\\t_{48}= 11+423\\t_{48}=434

Please help !
Talja [164]

Answer:

1. rational number

2. a positive rational number

Step-by-step explanation:

A rational number is a number that can be expressed as a simple fraction. When two rational numbers are multiplied together, the only logical answer would be for the outcome/product to also be rational.

The reciprocal of a positive rational number is also a positive rational number because if the original number was negative, the reciprocal would also be negative since the signs wouldn't change (in this case, the original number is positive). Since the original number is already a rational number, just by flipping it (the reciprocal), it would not change to an irrational, but instead stay the same.

What is the center of the circle (x + 2)2 + (y - 5)2 = 2.25?
avanturin [10]
This equation of the circle is in a center-radius form which is more generally written as,
                            (x - h)² + (y - k)² = r²
From the equation, the center of the circle is (h,k) and r is the radius. From the given equation above, the center of the circle is (-2,5).
