A person invested $2,500 in an account growing at a rate allowing the money to

sveta [45]

Answer:

Step-by-step explanation:

A person invested $2,500 in an account growing at a rate allowing the money to double every 11 years. How long, to the nearest tenth of a year would it take for the

value of the account to reach $3,800?

The formula for exponential growth given as:

A(t) = Ao (1/2)^t/t½

A(t) = Amount after time t = $3,800

Ao = Initial amount invested = $2500

t = Time in years

t½ = Time it takes to double = 11 years

Hence,

3800 = 2500(1/2)^t/11

Divide both sides by 2500

3800/2500 = 2500(1/2)^t/11/2500

A direct variation function contains the points (–8, –6) and (12, 9). Which equation represents the function?

mamaluj [8]

Answer:

Option C. $y=(3/4)x$

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form $y/x=k$ or $y=kx$

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

Find the value of the constant k

For the point (-8,-6)

$k=y/x=(-6/-8)=3/4$

For the point (12,9)

$k=y/x=(9/12)=3/4$

Note A single point was required to find the constant k (because the line passes through the origin)

The equation is equal to

$y=(3/4)x$
