Vikentia [17]

Answer:

x= 1/4 +(-1/4) √65 or x= 1/4 + 1/4 √65

Step-by-step explanation:

x= −b±√b2−4ac /2a

x= −(1)±√(1)2−4(−2)(8) /2(−2)

x= −1±√65 /−4

x= 1/4 +(-1/4) √65 or x= 1/4 + 1/4 √65

URGENT!!!!!!!! PLEASE HELP ASAP TIMED!!!!!!!!!!!!!!!

barxatty [35]

Step-by-step explanation:

Given that,

Perpendicular = 17 units

Hypotenuse = 25 units

We need to find the value of x.

Using Pythagoras theorem to find x.

Hypotenuse² = base²+perpendicular²

25² = x² + 17²

x = 18.3 units

So, the value of x is equal to 18.3 units. No, the sides do not form a Pythagorean triplet.

Find the future value of an annuity due of $400 each quarter for 4 1 2 years at 13%, compounded quarterly. (Round your answer to

Flura [38]

Answer:

$9891.23

Step-by-step explanation:

The formula for future value of annuity due is:

$FV=P[\frac{(1+r)^{n}-1}{r}]*(1+r)$

Where,

FV is the future value of the annuity (what we need to find)
P is the periodic payment (here it is $400)
r is the interest rate per period (here 13% yearly interest is actually $\frac{13}{4}=3.25$ percent per period(quarter))
n is the number of periods (here the annuity is for $4\frac{1}{2}$ years, which is $4\frac{1}{2}*4=18$ periods, since quarterly and there are 4 quarters in 1 year)

Substituting all those values in the equation we get:

$FV=400[\frac{(1+0.0325)^{18}-1}{0.0325}]*(1+0.0325)\\=400[23.9497]*(1.0325)\\=9891.23$

Hence, the future value of the annuity due is $9891.23
