Javier had $305 in his bank account. His bank charges a fee of $7.50 each month that a balance is below $500. If he makes no other deposits or withdrawals, how much money is in Javier’s account at the end of three months?

Answers

Answer 1

7.50*3 = 22.50
305 - 22.50 = 282.50

Answer 2

Answer: [tex]\$282.5[/tex]

Step-by-step explanation:

Given : Javier had $305 in his bank account.

His bank charges a fee of $7.50 each month that a balance is below $500.

If he makes no other deposits or withdrawals, then the amount of deductions in Javier’s account at the end of three months will be :-

[tex]\$7.50\times3=\$22.5[/tex]

Now, the amount of money in Javier’s account at the end of three months :-

[tex]\$305-\$22.5=\$282.5[/tex]

2+1.25f=10−2.75f solve for f

Answers

Hey there!

2 + 1.25f = 10 - 2.75f
Add 2.75f to both sides.

1.25f + 2.75f = 4f

4f + 2 = 10
Subtract 2 from both sides.

4f = 8
Divide both sides by 4 to solve for f.

f = 2

I hope this helps!

The value of f is 0.02.

What is an expression ?

Expression is a formation of numbers and variables with mathematical operations.

According to the given question we have to solve for f or we can say we have to find the value of f for the given expression which is

2+1.25f=10−2.75f (lets multiply each term by 100 to remove

decimals )

∴ 200 + 125f = 1000 - 275f

125f + 275f = 1000 - 200

400f = 800

f = 800/400

f = 2.

As we have multiplied by 100 we have to divide by 100 we obtain the exact result.

So, 2/100 is = 0.02

f = 0.02.

Prove or disprove that the product of two irrational numbers is irrational

Answers

Hi. The statement you gave is somewhat true, but not always. I disprove this and there are tons of websites that can help you with more in depth explanation. Have a good day.

The product of two irrational numbers can be either rational or irrational.

The product of two irrational numbers is not always irrational. To understand this, let's consider an example and a counterexample.

Example of an Irrational Product

Take the square root of 2 (\/(2)) and the square root of 3 (\/(3)). Both of these numbers are irrational. Their product is:

\/2 × \/3 = \/6

Since \/6 cannot be expressed as a fraction of two integers (making it irrational), this is an example where the product of two irrational numbers is irrational.

Counterexample of a Rational Product

Now, consider another example with \/(2) and \/(2). Since both are irrational, their product is:

\/2 × \/2 = 2

Here, 2 is a rational number because it can be written as a fraction (2/1). Therefore, this is a counterexample where the product of two irrational numbers is rational.

In summary, the product of two irrational numbers can be either rational or irrational depending on the specific numbers involved.

b.= 0.14. find p(a | b).

Answers

B the answer to the problem

Final answer:

The conditional probability that event a will occur given that event b has occurred, denoted as p(a | b), is approximately 0.3 or 30%.

Explanation:

The question is asking for the conditional probability of the event a given that event b has occurred, written as p(a | b). In probability theory, the formula for conditional probability is p(a | b) = p(a ∩ b) / p(b). Here, we already know that p(a ∩ b) = 0.14 and p(b) = 0.46. Substituting these values into the formula gives us:

p(a | b) = 0.14 / 0.46 = 0.304347826.

So, the probability of event a occurring given that event b has occurred is approximately 0.3 or 30%.

if f'(2) = 3.1 and g'(2)=7.3 then the graph of f(x)+g(x) has slope 10.4 at x=2.True or false

Answers

For functions, its derivative on a certain variable is its slope. This means that the slope of f(2) is 3.1 and that of g(2) is equal to 7.3.

To determine the slope of the f(x) + g(x) in terms of x is equal to,
f'(x) + g'(x)
Then, substitute x with 2,
f'(2) + g'(2)
Substituting the known values,
3.1 + 7.3 = 10.4

Hence, the answer is TRUE.

Final answer:

The statement is true, as the slope of the graph of f(x)+g(x) at x=2 is the sum of the slopes of f and g at that point, which equals 10.4.

Explanation:

The statement is true.

In calculus, the derivative of a function at a particular point measures the rate at which the function is changing at that point. It is analogous to the slope of the tangent line to the graph of the function at that point.

When we are given that f'(2) = 3.1 and g'(2) = 7.3, these values represent the slopes of the functions f and g at x = 2, respectively.

To find the slope of f(x) + g(x) at x = 2, we simply add the slopes of f and g at that point. This is based on the rule that the derivative of the sum of two functions is the sum of their derivatives, or symbolically, (f+g)' = f' + g'.

Therefore, the slope of the graph of f(x)+g(x) at x=2 is indeed 10.4 (3.1 + 7.3).

Not clear if you're supposed to find a series solution to the ODE, or solve exactly then give the requested terms of the series expansion of the that solution...

The exact solution is easy enough to find. We can separate the variables:

[tex]y=1+2\displaystyle\sum_{n\ge1}\frac{\left(\frac{x^2}2\right)^n}{n!}[/tex]

How can you check to see if this equation is correct? 12+39=49

Answers

Use the equation 49 - 39 = ___ and see if you get 12. You can also flip it and use 49 - 12 = ___ and see if you get 39.

Answer:

By solving it.

Step-by-step explanation:

In order to see if the equation is correct, you just have to perform the operations in both sides of the inequality and then check if those are equal, that means that the equation is correct, for example if both sides of the equation give as a result 10 then the equation is correct, now let´s do it with the problem:

12+39=49

51=39

Since 51 is not equal to 39 that means that the equation is not correct.

I REALLY NEED HELP WITH MY CALC CORRECTIONS. THIS IS THE THIRD TIME IVE POSTED THIS. I NEED HELP ASAP PLS!! I HATE CALC 1

Answers

1. As x approaches 1, f(x) approaches 3-1, that is 2.

If a = 2 and b = 3, f(1) = 2(1)^2 + 3(1) = 5

So there is a 'jump' in values of x at x = 1. So its not continuous at x=1.

2. For continuity at x = 1, ax^2 + bx must = 2 that is when a + b = 2.

3. for continuity at x = 2 , ax^2 + bx must be = 0 that is when a*2^2 + 2b = 0

- that is 4a + 2b = 0.

4. we have system of equations:-

a + b = 2
4a + 2b = 0

this gives a = -2 and b = 4 So f(x) is continuous when a = -2 and b = 4.

By decreasing each dimension by 1 unit, the area of a rectangle decreased from 40 square feet (on the left) to 28 square feet (on the right). Find the percent decrease in area.

Answers

Attached a pic of the solution (s).

Final answer:

The percent decrease in the area of a rectangle from 40 square feet to 28 square feet is calculated by dividing the difference in areas (12 sq ft) by the original area (40 sq ft) and multiplying by 100%. The result is a 30% decrease in area.

Explanation:

The percent decrease in the area of a rectangle can be found by first calculating the difference in the areas and then dividing that difference by the original area. In this case, the original area of the rectangle was 40 square feet and it decreased to 28 square feet, a difference of 12 square feet.

We use the formula for percentage change which is:

(change in value) / (original value) × 100%

Here, the change in value is the difference in areas (12 square feet) and the original value is the original area of the rectangle (40 square feet). Thus we calculate:

(12 sq ft/ 40 sq ft) * 100% = 30%

So, the percent decrease in the area of the rectangle is 30%.
