What is the simplified form of the quantity 4 z squared minus 16z plus 15 over the quantity 2 z squared minus 11 z plus 15?
sleet_krkn [62]

Answer:

\frac{(2z-3)}{(z-3)}

Step-by-step explanation:

\frac{4z^2-16z+15}{2z^2-11z+15}

To simplify this we factor the numerator and denominator separately

factor 4z^2 - 16z+15

We apply 'ac' method, 4* 15 = 60

-10 * -6 = 60

-10 - 6 = -16

Now we split -16z using factors -10z -6z

4z^2 - 10z-6z+15

Take out GCf from first two terms and last two terms

2z(2z-5)-3(2z+5)

(2z-3)(2z-5)

factor 2z^2 - 11z+15

We apply 'ac' method, 2* 15 = 30

-5 * -6 = 30

-5 - 6 = -11

Now we split -11z using factors -5z -6z

2z^2 - 5z-6z+15

Take out GCf from first two terms and last two terms

z(2z-5)-3(2z-5)

(z-3)(2z-5)

Now we replace the factors

\frac{(2z-3)(2z-5)}{(z-3)(2z-5)}

Cancel out 2z-5 at the top and bottom

\frac{(2z-3)}{(z-3)}

Help!!!!
joja [24]

Answer:

0.28 yr  

Step-by-step explanation:

To find the doubling time with continuous compounding, we should look at the formula:

FV = PVe^{rt}

FV = future value, and

PV = present value

If FV is twice the PV, we can calculate the doubling time, t

\begin{array}{rcl}2 & = & e^{rt}\\\ln 2 & = & rt\\t & = & \dfrac{\ln 2}{r} \\\end{array}

1. Samuel's doubling time

\begin{array}{rcl}t & = & \dfrac{\ln 2}{0.055}\\\\& = & \textbf{12.603 yr}\\\end{array}

2. Claire's doubling time

\begin{array}{rcl}t & = & \dfrac{\ln 2}{0.05625}\\\\& = & \textbf{12.323 yr}\\\end{array}

3. Samuel's doubling time vs Claire's

12.603 - 12.323 = 0.28 yr

It would take 0.28 yr longer for Samuel's money to double than Claire's.

Find the value of X in that isosceles triangle shown below
ipn [44]

Answer:

sqrt(13) =x

Step-by-step explanation:

We have 2 right triangles, one on the right and one on the left

The base is 1/2 of 4 or 2 and the height is 3

We can use the Pythagorean theorem to find the hypotenuse

a^2 + b^2 = c^2

2^2 + 3^2 = x^2

4+9 = x^2

13 = x^2

Take the square root of each side

sqrt(13) =x
