Answer:

b

Step-by-step explanation:

complex solutions occur in conjugate pairs, hence

\sqrt{7} + 5i , then \sqrt{7} - 5i is also a solution

Answer:

Option b). the other solution to the function is \sqrt{7}-5i

Step-by-step explanation:

In a given quadratic function f(x) = ax² + bx + c, if b² - 4ac < 0 then bothe the solutions of the function will have two complex roots.

Roots of this function will be the complex conjugates.

Since one root of the equation is given as \sqrt{7}+5i

Then other solution will be its complex conjugate as \sqrt{7}-5i

Therefore, Option B) will be the answer.

Which is the equation for the line perpendicular to y = –5/3 x + 11 1/3 and containing P(–2, 3)?
kati45 [8]
Okay, to answer this question, 
<span>Perpendicular lines have slopes that are inverse of one another and with opposite signs so, 
If a line has a slope of m= -2 than a perpendicular line will have slope m=1/2
If a line has a slope of m= -3/4 than a perpendicular line will have slope m=4/3 If a line has a slope of m= 6 than a perpendicular line will have slope m=-1/6

So, just find the slope of your line, using it, get the slope of the line that will be perpendicular and then just get the equation for a line that has that slope and passes through point (-2,3) using: y - y1 = m(x - x1)
I hope I helped you with my answer</span>

The growth of 100 young trees near a river is given below. At most 50 yards from the river (Event Y) More than 50 yards from the
Alona [7]

Answer:

It is 91% more likely that the tree was atmost 500 yards from the river.

<h3>Step-by-step explanation:</h3>

We are given with distance and height of 100 young trees near a river.

From that table, in total there are 55 trees which grow more than 3 ft during the year.

And among those 55 trees, 50 trees are atmost 50 yards from river.

Hence it is ≈91% more likely that the tree was atmost 50 yards from the river.

Otrada [13]

Answer:

10

Step-by-step explanation:

i think its 10 maybe cuz if u see

the perimeter of a rectangular room is 52 feet. right?

then then height is 2 more than the width. what is the width of the room? so am I right copying the question? yes the question is right copied ok!

now see when u subtract 2 from 12 it gives u 10 and length i as 2 more than the width so maybe 10
