Answer:
[tex] \frac{1}{81} [/tex]
Step-by-step explanation:
express that with a positive exponent using this:
[tex] {a}^{ - n} \frac{1}{ {a}^{n} } [/tex]
so ..
[tex] {9}^{ - 2} = \frac{1}{ {9}^{2} } [/tex]
now you have to evaluate the exponent/ power
so..
[tex] \frac{1}{ {9}^{2} } = \frac{1}{81} [/tex]
why 81 ?
because the exponent of 9 is 2 so you have to multiple 9 by itself so
9x9=81
so the answer is
[tex] \frac{1}{ {81}^{} } [/tex]
sorry for the bad english hehe

Write a function in terms of t that represents the situation.
An item costs $4.50, and its price increases by 3.5%
each year.
Answer:
4.5(1.035)^t
Step-by-step explanation:
An inrease of 3.5% means that each year's total is 103.5% of the year before, right?
Year 1 = 4.5(1.035) = 4.66
Year 2 = 4.66(1.035) = 4.82
etc.
So, year 2 is 4.5(1.035)(1.035) = 4.82
Multiplying something by itself can be written with an exponent instead, so 2 years is...
4.5(1.035)2
Since the number of years is the variable (let's call it t)...

Lin's father is paying for a $20 meal. He has a 15%-off coupon for the meal. After the discount, a 7% sales tax is applied. What does Lin's father pay for the meal? Explain or show your reasoning.
Answer:
$18.19
Step-by-step explanation:
20 decrease 15% =
20 × (1 - 15%) = 20 × (1 - 0.15) = 17
17 increase 7% =
17 × (1 + 7%) = 17 × (1 + 0.07) = 18.19

What is an equivalent fractions
Answer:
fractions that are the same
make m the subject of the formula
G = √m-5 /2
g² = m-5 /2
2 × g² = m - 5
2g² = m - 5
2g² + 5 = m
So, m = 2g² + 5
Answer:
m = 2G²+5
Step-by-step explanation:
G²= m-5/2
2g² = m-5
2g² +5 = m
m = 2G²+5

A dog weighs 60 N on planet Earth. On the moon, he would weigh about
176 (one-sixth) of what he does on Earth. How much does the dog weigh on
the moon?
Answer:
16.09N
Step-by-step explanation:
Answer:
[tex]\boxed{\purple{\textsf{The weight of the dog on moon is \textbf{10 Newtons. }}}}[/tex]
Step-by-step explanation:
Given that the weight of the dog on the earth is 60N . We need to find the weight of dog on the moon. So we know that the weight of an object is one sixth the weight of an object on the moon. In other words the acceleration due to gravity is one sixth on the moon that of earth. We can use a formula as ,
[tex]\qquad\boxed{\boxed{\sf Weight_{(On \ moon )}= \dfrac{1}{6}\times Weight_{(On \ earth )}}}[/tex]
On substituting the respective values :-
[tex]\sf\implies Weight_{(On \ moon )} = \dfrac{1}{6}\times Weight_{(On \ earth )} \\\\\sf\implies Weight_{(On \ moon )} =\dfrac{1}{6}\times 60 N \\\\\sf\implies\boxed{\pink{\frak{ Weight_{(On \ moon )}= 10 \ Newtons }}}[/tex]
