The roots of x2 − ( ) + 34 are 5 ± 3i.

Answers

Answer 1

Answer: use quadratic formula
if you had ax^2+bx+c=0, then
x= $\frac{-b+/- \sqrt{b^(2)-4ac} }{2a}$
a=1
b=?
c=34
subsitute
$\frac{-b+/- \sqrt{b^(2)-4(1)(34)} }{2(1)}$ =5+/-3i
$\frac{-b+/- \sqrt{b^(2)-136} }{2}$ =5+/-3i
make 5+/-3 into fraction over 2,(10+/-6i)/2
$\frac{-b+/- \sqrt{b^(2)-136} }{2}$ =(10+/-6i)/2
multiply both sides by 2
$-b+/- \sqrt{b^(2)-136}$ =10+/-6i
we conclude that -b=10
b=-10

ok so equaton is
x^2-10x+34

Answer 2

Answer:

The roots of x² -bx+34=0 are 5 ± 3i. Then b = ?

-------------------

Vieta's formulas :

5 - 3i + 5 + 3i = b ⇒ b =10

Now, we have the equation:

x² -10x + 34 = 0

a sailfish can swim up to 1 mile per hour less than one fifth the top speed of a peregrine falcon. Find the top speed that a sailfish can swim?

Answers

top speed of a peregrine falcon is 240 miles per hour

240 x 1/5 = 48

48-1 = 47

sailfish can swim 47 miles per hour

Answer: The top speed that a sailfish can swim at $((x)/(5)-1)\ mph$

Step-by-step explanation:

Since we have given that

Top speed of a peregrine falcon be 'x'.

One fifth the top speed of a peregrine falcon would be

$(1)/(5)x$

1 mile per hour less than the above is expressed as

$(1)/(5)x-1$

According to question, the top speed that a sailfish can swim would be

$(1)/(5)x-1$

Hence, the top speed that a sailfish can swim at $((x)/(5)-1)\ mph$
