Answer:
2* 8n* 8n* 8n*8n
Step-by-step explanation:
Break it down 2(8n)^4 because 4 is the exponent you will multiply 8n four times so it will be 8n*8n*8n*8n so add the 2 to it and it will be 2*8n*8n*8n*8n. Hope this help :)
The expression 2(8n)⁴ is equivalent to 2¹³n⁴ or 8192n⁴ after simplifying.
What is an expression?It is defined as the combination of constants and variables with mathematical operators.
We have:
[tex]\rm = 2(8n)^4[/tex]
[tex]\rm 2\times 8^4\times n^4\\\\\rm 2\times (2^3)^4\times n^4\\\\\rm 2\times 2^1^2\times n^4\\\\\rm 2^1^3\times n^4\\\\\\\rm 2^1^3 n^4\\\\or\\\\8192n^4[/tex]
Thus, the expression 2(8n)⁴ is equivalent to 2¹³n⁴ or 8192n⁴ after simplifying.

shopkeeper sells tins of the same dog food in packs of four or packs of six.
Packs of four tins cost £1. Packs of six tins cost £1.20
Which is the best value for money?
You must show your working.
Answer:
Pack of 6
Step-by-step explanation:
Pack of 4 = £1
Packs of 6 = £1.20
Price per unit of each pack:
Pack of 4 ;
Unit price : cost / units
Unit price = £1 / 4 = £0.25
Pack of 6 ;
Unit price : cost / units
Unit price = £1.20 / 6 = £0.20
Pack of 6 is the best value for money as it has a lower unit price

Step-by-step explanation:
The sinusoidal function f(x)=33sin(7x−π12)+33 models the height, in centimeters, that a valve stem of the a tire is above ground x seconds after the tire begins to rotate.
How long does it take the valve stem to complete one revolution?
Answer:
0.90 seconds
Step-by-step explanation:
We will see that one complete revolution takes (2π/7) seconds.
How long does it take the valve stem to complete one revolution?Here we have the function:
f(x) = 33sin(7x−π/12) + 33
The time needed to do a full revolution is given by the period of the function.
Remember that:
sin(x) = sin(x + 2π).
Then:
sin(7x−π/12) = sin(7*(x + T) −π/12)
Then we must have:
2π = 7*T
Where T is the period.
Solving for T, we have:
2π/7 = T
This means that one complete revolution takes (2π/7) seconds.

Miguel is ordering 6 bags of cat food from Canada. Each bag has a mass of 7.5 kg. To determine the shipping costs, Miguel needs to know the total weight in pounds. What is the weight of the cat food in pounds? Use 1 kg = 2.2 lbs and do not round any computations.
Answer:
99 pounds
Step-by-step explanation:
7.5×6=45kg
1kg=2.2lb and we have 45kg because this is direct proportion what you do to one side you havbe to do to the other
so 2.2lb×45 gives you 99 pounds

Step-by-step explanation:
A website received 2500 registered members in July. And the number of registered members in August decreased to 2245. What was the percentage decrease in the number of registered members?
Number of registrations a website received during July = 2500
Number of registrations a website received during August = 2245
Number by which the registrations decreased :
[tex] =\tt 2500 - 2245[/tex]
[tex] =\tt 255[/tex]
Thus, the registrations decreased by 255.
Let x be the perrcentage of decrease.
Which means :
[tex] =\tt 255 = \frac{x}{100} \: of \: 2500[/tex]
[tex] = \tt255 = \frac{x \times 2500}{100} [/tex]
[tex] =\tt 255 = \frac{2500x}{100} [/tex]
[tex] = \tt255 \times 100 = 2500x[/tex]
[tex] = \tt25500 = 2500x[/tex]
[tex] =\tt \frac{25000}{2500} = x[/tex]
[tex]\color{plum} =\tt \bold{10.2\%}[/tex]
▪︎Thus, the percentage of decrease in the number of registered members = 10.2%
A famous monument is 300 ft tall. When it casts 210-ft shadow, a nearby tree casts a shadow that is 27 ft long. About how tall is the tree?
Answer:
38.57 feets
Step-by-step explanation:
Given that:
Height of monument, h = 300ft
Shadow of monument, s = 210 ft
Shadow of tree, s = 27ft
Height of tree, = x
Using the relation :
Height / shadow = height / shadow
Monument = tree
300 / 210 = h / 27
Cross multiply
300 * 27 = 210 * h
8100 = 210h
h = 8100 / 210
h = 38.57 feets
