Simplify the expression.
(5-5i)-(-6-3i)
Answer:
11-2i
Step-by-step explanation:
Distribute the negative
5-5i+6-3i
Combine like terms
11-2i
Hope this helped!!
Have a nice day!
Answer:
[tex]\boxed{\sf 11-2i}[/tex]
Step-by-step explanation:
[tex]\sf (5-5i)-(-6-3i)[/tex]
Opposite of -6 - 3i is 6+3i:
[tex]\sf 5-5i+(6+3i)[/tex]
Combine real and imaginary numbers 5-5i and 6+3i:
[tex]\sf 5+6+(-5+3)i[/tex]
Add 5 to 6, and -5 to 3:
[tex]\sf 11-2i[/tex]

How many roots ( real and complex) describe the given polynomial function?
f(x)=x^3 +9x
A. three real roots
B . one real root and two complex roots
C. three complex roots
D. two real roots and one complex roots
Answer: d
Step-by-step explanation:
because after you multiply x 3 times you can use the 3 would be the square root of the number you got and a complex root you can't do that
For example: 9 x 3 = 27 the square root of 27 is 5.2 and that's is rounded
If an = 3n - 4, what is a5?
Answer:
[tex]11[/tex]
Step-by-step explanation:
[tex]an = 3n - 4[/tex]
To solve this put 5 Instead of n
[tex]a5 = 3 \times 5 - 4 \\ = 15 - 4 \\ = 11[/tex]
Hope this helps you.

The first four numbers of the pattern are 4., 3.6, 3.2, and 2.8 . Find the next three numbers in the pattern
Answer:
Step-by-step explanation:
4 - 0.4 = 3.6
3.6 - 0.4 = 3.2
2.8 - 0.4 = 2.4
2.4 - 0.4 = 2
2 - 0.4 = 1.6
so the next numbers in the pattern are: 2.4, 2 and 1.6
in group of 60 students, 15 liked math only , 20 liked science only and 5 did not like any two subject how many student like math
Answer:
i) no. of students like none of subject = 5
total no. of students= 69
=> no. of students like at least one subject= 60-5
= 55
ii) no. of students like math only = 15
no. of students like science only = 20
total no. of students like only one subject= 35
no. of students like none subject = 5
=> no of students like both the subjects = 60-(35+5) =20
(iii) no. of students like math= 15+ 20
= 35 ( because 15 like math only and 20 like both)
(iv) no. of students like science= 20+20
= 40 ( because 20 like science only and 20 like both )
Step-by-step explanation:
Answer:
35 kids.
Step-by-step explanation:
55 kids who like math or science
15 math only and 20 science only
s0 20 who like both math and science
so 35 kids who like math

Evaluate the function
f(x) = - 2x^2 + 2x + 4
Find f(1)
Answer:
5
Step-by-step explanation:
To evaluate [tex]f(x)=-2x^2+2x+4[/tex] at [tex]x=1[/tex], we must replace the x with 1
[tex]f(1)=-1(1)^2+2(1)+4\\f(1)=-1(1)+2+4\\f(1)=-1+6\\f(1)=5[/tex]

Answer:
- 3, - 2, - 1 and 6
Step-by-step explanation:
To find the first 3 terms, substitute n = 1, 2, 3 into the nth term rule
a₁ = 1 - 4 = - 3
a₂ = 2 - 4 = - 2
a₃ = 3 - 4 = - 1
The first 3 terms are - 3, - 2, - 1
similarly substitute n = 10 into the rule for 10th term
a₁₀ = 10 - 4 = 6

Find the measure of the angle indicated
Answer:
137 degrees
Step-by-step explanation:
in the triangle with 60 degrees : the top angle must be also 45 degrees (the same as the angle above it).
then its third angle must be 180 - 60 - 45 = 75 degrees (because the sum of all angles is always 180 degrees in any triangle).
then the sum of this 75 degrees angle, then the neighboring 68 degree angle and the next one (the left angle in the triangle with 100 degrees) together must be again 180 degrees, because all angles around a point on one side of a line are 180 degrees (a half circle).
that means this left angle of the 100 degrees triangle is
180 - 75 - 68 = 37 degrees.
that means that the right angle of the 100 degrees triangle is
180 - 37 - 100 = 43 degrees (again, because of the sum in a triangle).
and now that gives us the ? angle as
180 - 43 = 137 degrees
because this is again the sum around s point on a line (the line is the arrow line starting at the 100 degrees angle pointing leading and pointing to the bottom right).
