An exponential function has a starting value of 13 and a growth rate of 0.78%. Write an equation to model the situation.

Elina [12.6K]

Answer:

The equation that models the situation is $A(t) = 13(1.0078)^t$

Step-by-step explanation:

Exponential equation:

An exponential equation has the following format:

$A(t) = A(0)(1+r)^t$

In which A(0) is the starting value and r is the growth rate, as a decimal.

Starting value of 13 and a growth rate of 0.78%.

This means that $A(0) = 13, r = 0.0078$

Write an equation to model the situation.

$A(t) = A(0)(1+r)^t$

$A(t) = 13(1+0.0078)^t$

$A(t) = 13(1.0078)^t$

The equation that models the situation is $A(t) = 13(1.0078)^t$

Expand the expression (5x + 3)2, and write the result in standard form.

grin007 [14]

$(5x+3)^2\\\\\text{use}\ (a+b)^2=a^2+2ab+b^2\\\\=(5x)^2+2(5x)(3)+3^2\\\\=5^2x^2+30x+9\\\\=25x^2+30x+9\to D.$

Perform the indicated operation. Simplify the result in factored form. ((x - y)/ (x^2 - 1)) * ((x - 1)/(x^2 - y^2))

Scilla [17]

Answer:

The answer to your question is $\frac{1}{(x + 1)(x + y)}$

Step-by-step explanation:

Real operation

$\frac{x - y}{x^{2} - 1} \frac{x - 1}{x^{2} - y^{2}}$

Process

1.- Factor the denominators

$\frac{x - y}{(x + 1)(x - 1)} \frac{x - 1}{(x + y)(x - y)}$

2.- Simplify like terms

Cancel (x - y) and (x - 1) because they are in numerator and the denominator

$\frac{1}{(x + 1)(x + y)}$ This is the answer or you can expand

3.- Expand

$\frac{1}{x^{2} + xy + x + y^{2}}$
