Answer: Y = 6

Step-by-step explanation: The equation is this because when you put this equation on a graph, it makes a horizontal line passing through (3,6). When an equation is like Y = 6 it will make a horizontal line on that coordinate of Y, but if it is X = 6 it will make a vertical line on the coordinate of X.

A family wants to save for college tuition for their daughter. What continuous yearly interest rate r% is needed in their saving

sergey [27]

Answer:

The continuous yearly interest is 22.5% per year.

Step-by-step explanation:

Continuous yearly interest:

Continuous yearly interest is defined as the sum of the interest comes from principle and the interest comes from interest.

The formula for continuous interest yearly is

$A=Pe^{rt}$

where A = The final amount =$110,000

P= principle =$4,700

r= rate of interest

t= time (in year)= 14 years

$\therefore 110,000= 4,700e^{r\times 14}$

$\Rightarrow e^{14r}= \frac{110,000}{4,700}$

Taking ln both sides

$\Rightarrow ln e^{14r}= ln(\frac{110,000}{4,700})$

$\Rightarrow {14r}= ln(\frac{1100}{47})$

$\Rightarrow r=\frac{ln( \frac{1100}{47})}{14}$

$\Rightarrow r = 0.225$ (approx)

The continuous yearly interest is 0.225 = 22.5% per year.

Evaluate find the degree of a polynomial (y³-2)(y²+11)

jasenka [17]

Answer:

Step-by-step explanation:

$(y^3 - 2)(y^2 +11)$

$= y^3 (y^2 +11)-2(y^2 +11)$

$= y^5 +11y^3-2y^2 - 22$

Here, highest power of the variable is 5.

Therefore, degree of the given polynomial is 5.
