5) 74.925
6) 470
i think this is correct but i'm not completely sure
Answer:
The expressions which equivalent to
are:
⇒ B
⇒ C
Step-by-step explanation:
Let us revise some rules of exponent
Now let us find the equivalent expressions of ![(2)^{n+3}](https://tex.z-dn.net/?f=%282%29%5E%7Bn%2B3%7D)
A.
∵ 4 = 2 × 2
∴ 4 = ![2^{2}](https://tex.z-dn.net/?f=2%5E%7B2%7D)
∴
=
- By using the second rule above multiply 2 and (n + 2)
∵ 2(n + 2) = 2n + 4
∴
=
B.
∵ 4 = 2 × 2
∴ 4 = 2²
∴
= 2² ×
- By using the first rule rule add the exponents of 2
∵ 2 + n + 1 = n + 3
∴
=
C.
∵ 8 = 2 × 2 × 2
∴ 8 = 2³
∴
= 2³ ×
- By using the first rule rule add the exponents of 2
∵ 3 + n = n + 3
∴
=
D.
∵ 16 = 2 × 2 × 2 × 2
∴ 16 = ![2^{4}](https://tex.z-dn.net/?f=2%5E%7B4%7D)
∴
=
×
- By using the first rule rule add the exponents of 2
∵ 4 + n = n + 4
∴
=
E.
is in its simplest form
The expressions which equivalent to
are:
⇒ B
⇒ C
A
Step-by-step explanation:
First and foremost, we can rule out B and C because they are less than one and would make the hexagon smaller instead of bigger. Now, when we measure the units, we see that it goes up by 2 squares on the graph. So, by process of elimination and measurement, we get the answer of A.
Answer:
Answer → C) 121°
Step-by-step explanation:
» Let the wanted angle be x
![{ \tt{x = 121 \degree}} \\ { \tt{ \{alternate \: angles \}}}](https://tex.z-dn.net/?f=%7B%20%5Ctt%7Bx%20%3D%20121%20%5Cdegree%7D%7D%20%5C%5C%20%20%7B%20%5Ctt%7B%20%5C%7Balternate%20%5C%3A%20angles%20%5C%7D%7D%7D)
65% of 39 is 60 the answer is 60
