Answer:
we can describe the parts of the expression that the arrows
point to 3x-2 such as:
↑(x variable)
← (2 constant)
↓
(3 coefficient)
Step-by-step explanation:
Given the expression
- As we have to describe the parts of the expression the arrows
point to .
we can describe the parts of the expression that the arrows
point to 3x-2 such as:
↑(x variable)
← (2 constant)
↓
(3 coefficient)
Therefore, it is clear that:
- The upper arrow '↑' points to the variable part 'x' of expression which is 'x'.
- The lower arrow '↓' points to the coefficient part of the expression which is '3'.
- The arrow '←' points to the constant part of the expression which is '2'.
Answer:
The explicit formula of the given AP is a(n) = 7 + 7 n
And the term a (13) = 98
Step-by-step explanation:
Here, the given sequence is : 14, 28 , 42, 56 ,....
First Term (a) = 14
Second term = 28
Now, the Common difference (d) = Second term - First Term
= 28 - 14 = 14
Now, the formula for nth term in an AP is : a(n) = a + (n-1)d
So, here, the nth term of the sequence is given as:
a(n) = 14 + (n-1) 7
= 14 + 7 n - 7 = 7 + 7 n
or, a(n) = 7 + 7 n ......... (1)
or, The explicit formula of the given AP is a(n) = 7 + 7 n
Now, for evaluating a (13) put n = 13 in (1)
⇒ a(13) = 7 + 7 (13) = 7 + 91 = 98
or, a (13) = 98
Answer:
<em>33 degrees</em>
Step-by-step explanation:
Complementary angles are 90 degrees when added.
So to find the measure of the other angle just subtract 57 from 90.
90 - 57 = 33
Answer:
D
Step-by-step explanation:
Neither Alex nor Jo are correct, because surface area is a 2-dimensional quantity, so it would be given in just square units, not linear nor cubic.
