$800 is invested at a rate of 7%. What will be the total amount of the investment after 3 1/2 years?
torisob [31]

Answer:

A = $996.00

Step-by-step explanation:

(I = A - P = $196.00)

Equation:

A = P(1 + rt)

Where:

A = Total Accrued Amount (principal + interest)

P = Principal Amount

I = Interest Amount

r = Rate of Interest per year in decimal; r = R/100

R = Rate of Interest per year as a percent; R = r * 100

t = Time Period involved in months or years

From the base formula, A = P(1 + rt) derived from A = P + I and I = Prt so A = P + I = P + Prt = P(1 + rt)

Calculation:

First, converting R percent to r a decimal

r = R/100 = 7%/100 = 0.07 per year.

Solving our equation:

A = 800(1 + (0.07 × 3.5)) = 996

A = $996.00

The total amount accrued, principal plus interest, from simple interest on a principal of $800.00 at a rate of 7% per year for 3.5 years is $996.00.

4. The graph of h(x) = x^2 was transformed to create the graph of k(x) = -4x^2? Which of these describes the transformation from
Viefleur [7K]

Answer:

A. A reflection over the x-axis and a vertical stretch.

Step-by-step explanation:

Let h(x) = x^{2}, to obtain k(x) = -4\cdot x^{2}, we need to use the following two operations:

(i) Vertical stretch

g(x) = k\cdot f(x), k\in \mathbb{R}^{+}

(ii) Reflection over the x-axis

g(x) = -f(x)

Let prove both transformations in h(x):

Step 1 - Vertical stretch (k = 4)

h'(x) = 4\cdot x^{2}

Step 2 - Reflection over the x-axis

k(x) = -4\cdot x^{2}

Hence, correct answer is A.
