Answer:
Step-by-step explanation:
After t years,
the first tree will be 13+4t feet tall
the second tree will be 27+½t feet tall.
When they are the same height,
13+4t = 27+½t
subtract ½t from both sides
13+3½t = 27
subtract 13 from both sides
3½t = 14
divide both sides by 3½
t = 14÷(3½) = 14÷(7/2) = 14× (2/7) = 4
The trees will be the same height in 4 years.

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)...

Answer:
packages: 1 grams: 11.6
packages:8 grams:92.8
grams: 116 packages: 10
Step-by-step explanation:
for the first, just divide 23.2/2=11.6
the grams of a package is 11.6
1x11.6=11.6
8x11.6=92.8
116/11.6=10

Consider a graph (not pictured) of a quadratic function g(x).
Which statement would be true of the graph of the function g(x+2)?
a.) The graph of g(x+2) is the result of a shift in the positive y-direction by 2 from the graph of g(x).
b.) The graph of g(x+2) is the result of a shift in the negative y-direction by 2 from the graph of g
c.) The graph of g(x+2) is the result of a shift in the positive x-direction by 2 from the graph of g
d.) The graph of g(x+2) is the result of a shift in the negative x-direction by 2 from the graph of g
Answer:
The answer is (B)
Step-by-step explanation:
Answer:
(D)
Step-by-step explanation:
The graph of g(x + 2) is the graph of g(x) shifted 2 units to the left
2 units to the left => "negative two units in the x-direction"
Solution: Option D

select the equivalent expression. (a^-2 • 8^7)^2
a. 8^9
b. (8a)^10
c. a^-4 • 8^14
Answer:
c.
Step-by-step explanation:
The equivalent expression of [tex](a^{-2}.8^{7} )^{2}[/tex] is [tex]a^{-4} .8^{14}[/tex].
What is an expression?An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division. The terms involved in an expression in math are:
Constant: A constant is a fixed numerical value.
Variable: A variable is a symbol that doesn't have a fixed value.
Term: A term can be a single constant, a single variable, or a combination of a variable and a constant combined with multiplication or division.
Coefficient: A coefficient is a number that is multiplied by a variable in an expression.
Given expression
[tex](a^{-2}.8^{7} )^{2}[/tex]
Using formula [tex]a^{-m} =\frac{1}{a^{m} }[/tex]
= [tex](\frac{8^{7} }{a^{2} } )^{2}[/tex]
= [tex]\frac{(8^{7}) ^{2} }{(a^{2}) ^{2}}[/tex]
Using [tex](a^{m} )^{n} =a^{m \times n}[/tex]
= [tex]\frac{8^{14} }{a^{4} }[/tex]
= [tex]a^{-4} .8^{14}[/tex]
Option C is correct.
The equivalent expression of [tex](a^{-2}.8^{7} )^{2}[/tex] is [tex]a^{-4} .8^{14}[/tex].

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]
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
PLS help me pls pls pls
Write an expression to show the final cost, in dollars, of x games when using the coupon.
Answer:
5x + 2.50 - 0.2
Step-by-step explanation:
The 5x is because each game (x) costs 5 dollars. You add 2.50 because that is how much extra you have to pay for the bowling shoes. To compensate for the -20% off of the total price, I added the -0.2 (20% as a decimal).
Note:
I am 100% sure about the "5x + 2.50 -" part. The 0.2 part not so much.
I hope this is correct and helps though!
pls help me with my homework
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]
