Please answer with formula and how to find it

It will take approximately 7.78 years for your salary at job A to exceed your salary at job B.

To solve this problem, we need to set up an equation. Let x represent the number of years that it will take for your salary at job A to exceed your salary at job B. We can use this equation to solve for x:

$46,000(1.05)^x > $55,000(1.02)^x

Now, let's simplify this equation to solve for x:

(1.05)^x > (1.02)^x * (55000/46000)

Taking the natural log of both sides of the equation:

xlog(1.05) > log(1.02) + log(55000/46000)

Solving for x:

x > [log(1.02) + log(55000/46000)]/log(1.05) ~ 7.78

It will take approximately 7.78 years for your salary at job A to exceed your salary at job B.

The number of medals did the United States win is 97 using the equation x + (x + 9) = 185.

Let x be the number of medals Russia won in the 2000 Summer Olympics. Then, since the United States won 9 more medals than Russia, the number of medals the United States won is x + 9.

Together, they won 185 medals, so we can write the equation:

x + (x + 9) = 185

Simplifying the left side, we get:

2x + 9 = 185

Subtracting 9 from both sides:

2x = 176

Dividing both sides by 2:

x = 88

So Russia won 88 medals, and the United States won 88 + 9 = 97 medals.

Therefore, the United States won 97 medals in the 2000 Summer Olympics.

The original price of the shoes was $26.

A coupon is a voucher or a code that can be used to get a discount or a special offer when making a purchase.

Let the original price of the shoes be x.

According to the problem, Martin gets a discount of $3 on the original price, so he pays (x - 3) dollars.

Then, the store takes 20% off the reduced price, which means Martin pays 80% of (x - 3) dollars.

We can write this information as an equation:

0.8(x - 3) = 18.4

Simplifying:

0.8x - 2.4 = 18.4

0.8x = 20.8

x = 26

the value of a is -7/4.

Simply change x in the original equation to -1/4 to determine the value of a:

y = 4x² - 7x - 2

y = 4(-1/4)² - 7(-1/4) - 2

y = 1 - (-7/4) - 2

y = 1/4 - 2

y = -7/4

Mathematically, an equation can be defined as a statement that supports the equality of two expressions, which are connected by the equals sign “=”

Two expressions are combined in an equation using an equal symbol ("="). The "left-hand side" and "right-hand side" of the equation are the two expressions on either side of the equals sign. Typically, we consider an equation's right side to be zero. As we can balance this by deducting the right-side expression from both sides' expressions, this won't reduce the generality.

from the question:

We must discover a solution for x before we can find the solutions to the equation y = 4x2 - 7x - 2. By calculating the quadratic equation while putting y equal to zero, we can achieve this:

4x² - 7x - 2 = 0

(4x + 1)(x - 2) = 0

This quadratic equation has two solutions:

4x + 1 = 0 or x - 2 = 0

4x = -1 or x = 2

x = -1/4 or x = 2

As a result, the equation has solutions a = -1/4 and b = 2, where a b.

Simply change x in the original equation to -1/4 to determine the value of a:

y = 4x² - 7x - 2

y = 4(-1/4)² - 7(-1/4) - 2

y = 1 - (-7/4) - 2

y = 1/4 - 2

y = -7/4

Answer:

(1.2075)

Step-by-step explanation:

Lets assume we are increasing a price on a $100 item to help visualize the steps.

The two steps of 5% and then 15% can each be expressed as:

5%:  (1+0.05)  [The 1 represents the fact that the final cost is full price (1) plus 5%(0.05)]

15%  (1+0.15)   [Same explanation, but now with 0.15 for 15%]

We can apply these factors individually:

Assume a base of $100:

5% increase would make it $105  [$100*(1.05)=$105]

15% increase:  On top of the 5%, we would go to:  $105*(1.15) = $120.75

Or we can use a single multiplier.

If we look at the steps from above, we see that the algebra consisted of taking the origianl price ($100) and multiplying it twice:  once with (1+0.05) and once with (1+1.15).  Write this in the form of an equation:

  ($100)*(1+0.05)*(1+0.15) = $120.75

Let's multiply (1+0.05)*(1+0.15)

                       = (1.2075)

We can use this single factor (multiplier) to find the correct/same value as before:

              (1.2075)($100) = $120.75

The amount in the account after 5 years would be $137.

Continuous compound interest is a method of calculating the interest earned on a principal amount that is continuously reinvested

P = $110

r = 0.041 (4.1% expressed as a decimal)

The perimeter of the triangle present in above figure is 42 dm. Then the value of x is equals to the 9 dm and all three sides of triangle are 9 dm, 11 dm and 22 dm.

We have a triangle present in above figure. The perimeter is the length of the boundaries of a shape. A triangle is a type of polygon with three sides. In other words, it is a closed two dimensional shape having three straight sides. So, perimeter of a triangle = sum of all three sides. Here, perimeter of triangle = 42 dm

Now, first side length of triangle= (3x - 5 ) dm

Second side length = (x + 2) dm

Third side length = x dm

Now, using perimeter formula for triangle,

=> 3x - 5 + x + x + 2 = 42

=> 5x = 42 + 5 - 2 = 45

=> x = 45/5 = 9

3x - 5 = 22 dm

logbA = 2.817 and logbB = 0.106 need to be used to find logb A/BA. We know that logarithms are important in mathematics and help us to solve complex problems involving exponents or roots.

They are expressed in terms of the logarithm base, which is the number or expression that is being raised to a power. It can be solved using the quotient rule of logarithms which states that logb (x / y) = logb x - logb y.

Explanation:
The given values are: logbA = 2.817 and logbB = 0.106Let us first use the quotient rule of logarithms to simplify the expression logb A/BA = logb A - logb BA. Using this rule, we get:

logb A/BA = logb A - logb B
Now we can substitute the given values in the above expression:

logb A/BA = 2.817 - 0.106
= 2.711

Therefore, the value of logb A/BA is 2.711. Hence, option (D) 2.711D is the correct answer.

To calculate the number of meters of tiles needed to purchase, we must first calculate the area of the pool. This can be done by multiplying the length by the width:

9m x 4m = 36m²

We then multiply this area by the depth of the pool to get the total volume:

36m² x 2.5m = 90m³

Now, to calculate the number of meters of tiles needed, we must divide the total cost of the tiles, including installation, by the cost of the tiles per meter:

90 pesos + 50 pesos = 140 pesos

140 pesos ÷ 90 pesos = 1.55 meters

Let's assume that the point has coordinates (-x, y), where x > 1 and y > 2.

Then, using the distance formula, we have:

r = √(x² + y²)

Since r > -3, we have:

√(x² + y²) > -3

x² + y² > 9

Now, absolute values of the coordinates is 5, we have:

a) The expected value for the weight of a randomly chosen apple from the box is 11/24.

b) The variance of the weight of a randomly chosen apple from the box is 19/72.

a) The expected value of the weight of a randomly chosen apple from the box can be calculated as:

E[Y] = E[E[Y|Z]] = E[1/(2Z)] = 1/2 * (1/2 + 1/4 + 1/6) = 11/24

Therefore, the expected value for the weight of a randomly chosen apple from the box is 11/24.

b) The variance of the weight of a randomly chosen apple from the box can be calculated as:

Var(Y) = E[Var(Y|Z)] + Var(E[Y|Z])

Since E[Y|Z=j] = 1/(2j) and E[Y²|Z=j] = 1/j, we have:

Var(Y|Z=j) = E[Y²|Z=j] - [E[Y|Z=j]]² = 1/j - (1/(2j))² = (3/4) * (1/j²)

Therefore, we can calculate the variance of Y as:

Var(Y) = E[Var(Y|Z)] + Var(E[Y|Z])

= 1/3 * (3/4 * (1/1²) + 3/4 * (1/2²) + 3/4 * (1/3²)) + Var(11/24)

= 1/4 * (1 + 1/4 + 1/9) + 0
