Answer:

It will take 23 years for the account to grow to $7000.

Step-by-step explanation:

Simple Interest

The simple interest formula is given by:

\(E = P*I*t\)

In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.

After t years, the total amount of money is:

\(T = E + P\)

Carly has a bank account with a balance of $3,575.

This means that \(P = 3575\)

The account pays simple interest at a rate of 4.15%.

This means that \(I = 0.0415\)

How long will it take for the account to grow to $7000?

\(T = 7000\)

The interest is:

\(T = E + P\)

\(E = T - P = 7000 - 3575 = 3425\)

Now we have to find t.

\(E = P*I*t\)

\(3425 = 3575*0.0415*t\)

\(t = \frac{3425}{3575*0.0415}\)

\(t = 23.1\)

Rounding to the nearest year, it will take 23 years for the account to grow to $7000.

Answer:

Brand A

Step-by-step explanation:

Brand A has a box of 25 forks for 1.99

Take the price per fork

1.99 /25 = .0796

              .08 per fork

Brand B has a box of 42 totals for 3.89

3.89 / 42

.092319048

.09 per fork

I guess it's option A or C ...

Rounding to the nearest cent, the estimated value of the vehicle after 4 years is approximately $23,726.20..

To estimate the value of the vehicle after 4 years, we can use the given equation A = 39500(0.86)^t, where A represents the value of the vehicle and t represents the number of years.

Substituting t = 4 into the equation:

A = 39500(0.86)^4

A ≈ 39500(0.5996)

A ≈ 23726.20

Rounding to the nearest cent, the estimated value of the vehicle after 4 years is approximately $23,726.20.

This estimation is based on the assumption that the vehicle's value decreases by 14% each year. The equation A = 39500(0.86)^t models the exponential decay of the vehicle's value over time. By raising the decay factor of 0.86 to the power of 4, we account for the 4-year period. The final result suggests that the value of the vehicle would be around $23,726.20 after 4 years of ownership.

Answer:

2 or 200%

Step-by-step explanation:If the growth rate doubled every week, it would grow by 100% per week. Since the growth rate triples every week, it grows by 200% per week. This is easy to see..... If 1 person is sick at the start.......by the end of the first week, 2 more would be sick. And 2 is 200% of 1. So, 3 people are sick at the end of the first week- triple that of the start. At the end of the second week,  6 more would be sick , and 6 is 200% of 3. So, 9 people total are sick at the end of the second week - triple that of the beginning of the second week

Answer:

The solution to the equation is \(x = 8\)

Step-by-step explanation:

To solve the equation, first we apply the distributive property on the parenthesis, then we isolate x.

Solution:

\(3(10 - x) = 6\)

Applying the distributive:

\(3*10 - 3*x = 6\)

\(30 - 3x = 6\)

Solving for x

\(3x = 30 - 6\)

\(3x = 24\)

\(x = \frac{24}{3}\)

\(x = 8\)

The solution to the equation is \(x = 8\)

the cost of labour per hour is $7.20

the cost of raw materials per pound is $11.60

For product one:

time = 5 hours of labour

let the cost labour per hour = x

Amount = 3 pounds of raw amterials

let the cost of one pound raw material = y

Cost to produce each product = $70.8

The equation:

time (cost per hour) + amount (cost of one pound of raw material) = Cost to produce each product

5(x) + 3(y) = 70.80

For product 2:

time = 3.5 hours of labour

let the cost of labour per hour = x

Amount = 13 pounds of raw amterials

let the cost of one pound raw material = y

Cost to produce each product = $176.00

The equation:

time (cost per hour) + amount (cost of one pound of raw material) = Cost to produce each product

3.5(x) + 13(y) = 176

combining both equations:

5x + 3y = 70.8 ...(1)

3.5x + 13y = 176 ....(2)

Using elimination method:

To eliminate y, we will multiply equation (1) by 13 and equation (2) by 3 so that both coefficient of y become the same

65x + 39y = 920.4 ...(*1)

10.5x + 39y = 528 ...(2*)

subtract equation (2*) from (1*):

65x - 10.5x + 39y - 39y = 920.4 - 528

54.5x + 0 = 392.4

54.5x = 392.4

divide both sides by 54.5:

x = 392.4/54.5

x = 7.2

substitute for x in any of the equations

Using equation 1: 5x + 3y = 70.8

Hence, the cost of labour per hour is $7.20 and the cost of raw materials per pound is $11.60

The factorization of p(x) is p(x) = (x + 5)^2 (x - 3).

There are different methods to find the zeros of a polynomial, but one common approach is to use the Rational Root Theorem to test possible rational roots and then use polynomial division to factor out the roots found.

The Rational Root Theorem states that if a polynomial with integer coefficients has a rational root p/q (where p and q are integers with no common factors other than 1), then p must divide the constant term and q must divide the leading coefficient.

In the case of p(x) = x³ + x² + 8x - 60, the constant term is -60 and the leading coefficient is 1, so the possible rational roots are of the form p/q, where p is a factor of -60 and q is a factor of 1. Therefore, the possible rational roots are ±1, ±2, ±3, ±4, ±5, ±6, ±10, ±12, ±15, ±20, ±30, ±60.

Since the remainder is not zero, x = 1 is not a root of p(x). We can repeat this process with each possible root until we find all the actual roots.

Using this method, we find that the zeros of p(x) are:

x = -5 (with multiplicity 2) and x = 3.

Therefore, the factorization of p(x) is:

p(x) = (x + 5)² (x - 3)

Answer:

Step-by-step explanation:

a + 1/10 = 5/10

Subtract 1/10 from both sides of the equation.

a + 1/10 = 5/10

-1/10 -1/10

a = 4/10

This answer is not incorrect but we usually need to simplify it if possible.

4/10 can be reduced to 2/5.

a = 2/5

Answer:

a=2/5

Step-by-step explanation:

To solve this, we first need to isolate the a so we can solve from there

First, we subtract 1/10. But whatever we do to one side we have to do to the other side. So when we subtract 1/10 from the left side we cancel it out and we subtract 1/10 from the right side so 5/10-1/10

So our equation becomes…

a=5/10-1/10

We can simplify this to…

a=4/10

4/10 is equal to 2/5

So that is our final answer

Now since we have nothing else to do that is our final answer

To evaluate the limit of the expression as x approaches 0, we can simplify the expression first.

The expression is given as lim(x approaches 0) (cosec(2x) - x cosec³(x)).

Using trigonometric identities, we can rewrite cosec(2x) as 1/sin(2x) and cosec³(x) as 1/(sin(x))³.

Distance = time * speed.

When Jose walks, his speed is 4 mph.

Then if he walks for X hours, the distance that he will travel is:
