Answer:

**The percentage increase is 1.1% to the nearest tenth**

The calculation can be done as follows

Original price= **$9.82**

increase=** $9.71**

Change in price= 9.82-9.71

= 0.11

**percent increase**= 0.11/9.82 × 100

= **1.12**

=** 1.1 (to the nearest tenth)**

**Hence the percent increase is 1.1%**

Answer:

**Answer:**

9.71 ÷ 9.82 = .9987 or 1% .

To reach a savings goal of $300,000 at the end of 25 years, you need to invest approximately $4,206.42 semiannually with a 5% interest rate compounded semiannually.

To calculate the amount of money you need to invest semiannually to reach a savings goal of $300,000 at the end of 25 years, you can use the formula for the future value of an annuity:

FV = P * ((1 + r/n)^(n*t) - 1) / (r/n)

Where FV is the future value, P is the amount you need to invest each period, r is the** interest rate** per period (5% in this case), n is the number of** compounding periods **per year (2 for semiannual compounding), and t is the number of years.

Inserting the given values into the formula:

FV = P * ((1 + 0.05/2)^(2*25) - 1) / (0.05/2)

Solving for P:

P = FV * (r/n) / ((1 + r/n)^(n*t) - 1)

Substituting the values:

P = 300,000 * (0.05/2) / ((1 + 0.05/2)^(2*25) - 1)

Calculating the value of P, we find:

P ≈ 4206.42

Therefore, you need to invest approximately $4,206.42 semiannually to reach your savings goal of $300,000 in 25 years.

**Answer:**

4 years

**Step-by-step explanation:**

**Answer:**

a. 20.5

**Step-by-step explanation:**

because this will form a right triangle we can use tan (opposite over adjacent) so an equation we could set up would be tan(70)=25/x

therefore we can just solve the equation which would give us 20.45. so if we round it the answer would be a

**Answer:**

The correct answer option is **a. 20.5 feet**.

**Step-by-step explanation:**

We are given that the angle of elevation of the ladder is 70° and the height of the ladder is 25 feet from the ground.

We are to find the distance of the building from the base of the ladder.

For this, we will use tan:

**x = 20.5 feet**

**Answer: Option 'd' is correct.**

**Step-by-step explanation:**

Since we have given that

Profit function of the store is given by

We need to find the maximum profit.

For this, we first derivate the above function:

Now, put P(x) = 0, we get that

Now, we will check that its maximality by finding the second derivative:

it gives maximum profit at x = 35 yards.

And the maximum profit would be

**Hence, Option 'd' is correct.**

x = E/W dimension

y = N/S dimension

4x + 4x + 2y + 2y = 64

8x + 4y = 64

4y = 64 - 8x

y = 16 - 2x

Area = xy = x(16 - 2x) = 16x - 2x^2

Maximum of y = ax^2 + bx + c is when x = -b / 2a

so x = -16 / -4 = 4

y = N/S dimension

4x + 4x + 2y + 2y = 64

8x + 4y = 64

4y = 64 - 8x

y = 16 - 2x

Area = xy = x(16 - 2x) = 16x - 2x^2

Maximum of y = ax^2 + bx + c is when x = -b / 2a

so x = -16 / -4 = 4

**Answer:**

40 goalas

**Step-by-step explanation:**

30% x ? = 12

12/30% =

12/(30/100) =

(100 x 12)/30 =

1,200/30 =
