Answer:
Position of the particle is 20.
Step-by-step explanation:
Position function is integration of velocity function.
Velocity function is integration of acceleration function.
So, let's integrate the given a(t) to get v(t)
If we integrate v(t) then we get s(t)
It is given the values of s(0) =0 and s(1)=20
So, position of the particle is difference of 20, 0. That's 20-0 =20.

If x increases by 7 in each row of a table of values, and the first differences are all equal to 45.5, then the rate of change is:
a) 6.5
b) 455/7
c) 7/455
d) 318.5
Answer:
b i think
Step-by-step explanation: dont yell just tell me if i got it wrong if i did srry
The rate of change when x increases and the first difference equal to 45.5 is 6.5. Then the correct option is A.
What is the slope?The slope is the ratio of rising or falling and running. The difference between the ordinate is called rise or fall and the difference between the abscissa is called run.
The slope is given as
[tex]\rm Slope = \dfrac{Rise \ or \ fall}{Run}[/tex]
If x increases by 7 in each row of a table of values and the first differences are all equal to 45.5. Then the rate of change will be given by the slope.
[tex]\rm \\Slope = \dfrac{45.5}{7} = 6.5[/tex]
The rate of change is 6.5.

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]

Suppose payments were made at the end of each month into an ordinary annuity earning interest at the rate of 2.5%/year compounded monthly. If the future value of the annuity after 10 years is $60,000, what was the size of each payment? (Round your answer to the nearest cent.) $
Answer:
Monthly payment= $440.71
Step-by-step explanation:
Giving the following information:
Mothly interest rate (i)= 0.025/12= 0.00208
Number of periods (n)= 12*10= 120 months
Future Value (FV)= $60,000
To calculate the monthly payment, we need to use the following formula:
Monthly payment= (FV*i) / [(1+i)^(n) - 1]
Monthly payment= (60,000*0.00208) / [(1.00208^120) - 1]
Monthly payment= $440.71

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

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
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]

44x = 220
x = 220/44
x = 5

Dakota earned $11.25 in interest in Account A and $25.00 in interest in Account B after 15 months. If the simple interest rate is 3% for Account A and 5% for Account B, which account has the greater principal? Explain.
Which account has the greater principal? Select the correct answer below and fill in the answer boxes to complete your choice.
Answer:
Step-by-step explanation:
I=Prt
11.25=A(0.03)(15/12)
11.25=A(0.0375)
A=11.25/(0.0375)
A=$300
25=B(0.05)(15/12)
25=B(0.0625)
B=25/(0.0625)
B=$400
So account B has the greater principal.

Sue has 4lbs 6oz of apples. Her younger brothers ate some and now she has 2lbs and 10oz how many lbs and oz of apples did they eat
Answer: 1 lbs 12 oz
Step-by-step explanation:
First and foremost, we should note that 16 ounces = 1 pound
Sue has 4lbs 6oz of apples. This in ounces will be:
= (4 × 16) + 6
= 64 + 6
= 70 ounces
Her younger brothers ate some and now she has 2lbs and 10oz. The ounces of apples left will be:
= (2 × 16) + 10
= 32 + 10
= 42 ounces
Therefore, the amount they ate will be:
= 70 ounces - 42 ounces
= 28 ounces
Since 16 ounces = 1 pounds
= 1 pounds 12 ounces
= 1 lbs 12 oz
