How do I express the letters in bracket as the subject of the formula ?
especially the 1/2 power is new and unfamiliar to me.
Answer:
[tex]n = 144m^2 - 1[/tex]
Step-by-step explanation:
__________________________________________________________
FACTS TO KNOW BEFORE SOLVING :-
Let x be a number. ⇒ [tex]x^{\frac{1}{2}}[/tex] can also be written as [tex]\sqrt{x}[/tex].To make any variable the subject of any formula , we need to isolate it.__________________________________________________________
According to the question ,
[tex]3m = \frac{(n + 1)^{\frac{1}{2} }}{4}[/tex]
Lets multiply both the sides by 4.
[tex]=> \frac{(n + 1)^{\frac{1}{2} }}{4} \times 4 = 3m \times 4[/tex]
[tex]=> (n + 1)^{\frac{1}{2} } = 12m[/tex]
It can be also written as :-
[tex]=> \sqrt{(n + 1)} = 12m[/tex]
Lets square both the sides.
[tex]=> [\sqrt{(n + 1)} ]^{2} = (12m)^{2}[/tex]
[tex]=> n + 1 =144m^2[/tex]
[tex]=> n = 144m^2 - 1[/tex]

Delaney is saving money in an account that offers 9% simple interest. She deposits 2000 from her grandmother into the account and makes no additional deposits or withdraws. How many years will it take to grow to 4,700
Answer:
15years
Step-by-step explanation:
Given data
Rate= 9%
Principal= $2000
Final amount= $4700
The simple interest formula is given as
A= P(1+rt)
Substitute
4700=2000(1+0.09*t)
4700= 2000+ 180t
4700-2000= 180t
2700=180t
t= 2700/180
t= 15 years
Hence the time is 15years
0/1 Autumn's dog eats the same amount of dog food every day. On day 3, the bag of dog food has 12 pounds of dog food. On day 7, the bag has 10 pounds of dog food. Write an equation that represents the amount of dog food in the bag, y, for any day after opening the bag of dog food, x. Show your work.
Answer:
y - 0.5x
Step-by-step explanation:
Given that the dog eats the same amount of food each day and on day 3, the available quantity of food
= 12 pounds
On day 7 (4 days after), the available quantity of food is 10 pounds. The difference in the amount of food in 4 days
= 12 - 10
= 2 pounds
This means that each day, the amount of food eaten by the dog in one day
= 2/4
= 0.5 pound
Hence the amount of dog food in the bag y for any day after opening the dog food x will be given as
= y - 0.5x

Answer:
x = 2
Step-by-step explanation:
Let's solve your equation step-by-step.
4 ( x − 1 ) = 2 ( 6 − 2 x )
Step 1: Simplify both sides of the equation.
4 ( x − 1 ) = 2 ( 6 − 2 x )
( 4 ) ( x ) + ( 4 ) ( − 1 ) = ( 2 ) ( 6 ) + ( 2 ) ( − 2 x ) (Distribute)
4 x + − 4 = 1 2 + − 4 x
4 x − 4 = − 4 x + 12
Step 2: Add 4 x to both sides.
4 x − 4 + 4 x = − 4 x + 12 + 4 x
8 x − 4 = 12
Step 3: Add 4 to both sides.
8 x − 4 + 4 = 12 + 4
8 x = 16
Step 4: Divide both sides by 8.
8 x / 8 = 16 / 8
x = 2

The cost c in dollars of manufacturing x bicycles at a production plant is given by th function shown below C(x)=5x^2-1000x+63,500. How many bicycles must be manufactured to minimize the cost
Answer:
100 bicycle
Step-by-step explanation:
Given the cost c in dollars of manufacturing x bicycles at a production plant expressed as C(x)=5x^2-1000x+63,500.
x is the number of bikes
To minimize the cost, dC/dx = 0
dC/dx = 10x - 1000
Since dC/dx = 0
0 = 10x - 1000
-10x = -1000
x = 1000/10
x = 100
Hence the number of bicycles that must be manufactured to minimize the cost is 100 bicycle

Answer:
2.828
Step-by-step explanation:
Pythagoras theorem (a^2)+(b^2)=(c^2)
also written as (base^2)+(altitude^2)=(hypotenuse^2)
Base=2
altitude=2
=Base = 2*2=4
=Altitude = 2*2=4
4+4
=8
√8
=2.828
Answer:
the answer is [tex]\sqrt 8[/tex], or 2.83 cm.
Step-by-step explanation:
You need to use the pythagorean theorem to solve this. It states that [tex]a^{2} + b^{2} = c^{2}[/tex]. a is one leg of the triangle, b is the other leg, and c is the hypotenuse (the slanted line that connects them). We need to do [tex]2^{2}[/tex] to find this. Since [tex]2^{2}[/tex] is 4, we know both legs are 4 [tex]cm^{2}[/tex]. 4 + 4 = 8. Since c is squared, we need to find the square root of 8, or just leave it as is. the final answer is [tex]\sqrt{8}[/tex], or 2.83. Hope this helped! :]

For volunteers picked up letter from the park Dominic you collect and 15 for your pieces a litter than Sarah Sarah collect the 12 more pieces in piper piper collected 1/4 as many pieces of litter as Vaughn Vaughn has collected nine more pieces of wood or than everyone else combine the X represent the number of pieces of litter Vaughn Collection
So many confusing details. So, I rephrase the question as:
Four volunteers picked up litters from the park.
Dominic collect 15 pieces less than Sarah. Sarah collects 12 more pieces than Piper. Piper collected 1/4 as many pieces of letter as Vaughn. Vaughn has collected nine more pieces of letter than everyone else combined. Let x represent the number of pieces of litter in Vaughn's Collection. Find x
Answer:
[tex]x = 72[/tex]
Step-by-step explanation:
Let:
[tex]D = Dominic;\ \ S = Sarah;\ \ P = Piper;\ \ V = Vaughn[/tex]
From the [rephrased] question, we have:
[tex]D = S - 15[/tex]
[tex]S = 12 + P[/tex]
[tex]P = \frac{1}{4}V[/tex]
[tex]V = 9 + D + S + P[/tex]
Substitute [tex]S = 12 + P[/tex] in [tex]D = S - 15[/tex]
[tex]D = 12 + P - 15[/tex]
[tex]D = P+12 - 15[/tex]
[tex]D = P-3[/tex]
Make V the subject in [tex]P = \frac{1}{4}V[/tex]
[tex]V = 4P[/tex]
Substitute: [tex]V = 4P[/tex], [tex]D = P-3[/tex] and [tex]S = 12 + P[/tex] in [tex]V = 9 + D + S + P[/tex]
[tex]4P= 9 + P - 3 + 12 + P +P[/tex]
Collect like terms
[tex]4P - P -P-P= 9 - 3 + 12[/tex]
[tex]P= 18[/tex]
Substitute [tex]P= 18[/tex] in [tex]S = 12 + P[/tex]
[tex]S = 12 +18[/tex]
[tex]S = 30[/tex]
Substitute [tex]S = 30[/tex] in [tex]D = S - 15[/tex]
[tex]D = 30 - 15[/tex]
[tex]D =15[/tex]
Substitute [tex]D =15[/tex], [tex]S = 30[/tex] and [tex]P= 18[/tex] in [tex]V = 9 + D + S + P[/tex]
[tex]V = 9 + 15 + 30 + 18[/tex]
[tex]V = 72[/tex]
x represents the number collected by Vaughan.
So:
[tex]x = 72[/tex]

Answer:
8x - 4y = 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 2 and c = - [tex]\frac{3}{4}[/tex] , then
y = 2x - [tex]\frac{3}{4}[/tex] ← in slope- intercept form
Multiply through by 4 to clear the fraction
4y = 8x - 3 ( subtract 4y from both sides )
0 = 8x - 4y - 3 ( add 3 to both sides )
3 = 8x - 4y , or
8x - 4y = 3 ← in standard form
