Answer:
In 2021 you would be 56 or 55 years old
Step-by-step explanation:
2021-1965=56 or the other way you could do it 52+4 because the other person said you would be 52 in 2017 so 4 years after you would be 55 or 56

Let r=1+2i and s=3+3i find r⋅s
The product of r.s is -3+9i.
r = 1+2i ; s = 3+3i
Product of r and s to be determine.
Any number with representation as a+bi is complex number.
Here,
r.s = (1+2i)(3+3i)
= 3+6i+3i+6i²
= 3+ 9i + 6(-1) (∵ i²=-1)
= 3 - 6 +9i
= -3 + 9i
Thus, the product of r.s is -3+9i.

Sally has 5 red flags, 3 green flags, and 4 white flags. how many 12-flag signals can she run up a flag pole
To solve for the total number of 12 – flag signals Sally can make, we need to make use of the formula:
total flags = d! / (a! b! c!)
Where,
d = is the number of flags to create a signal = 12
a = number of red flags = 5
b = number of green flags = 3
c = number of white flags = 4
We can observe from the equation that the individual number of flags is factored out (or divided from) that is because all the 5 red flags are similar, all the 3 flags are similar and all 4 flags are similar.
Going back into the equation, by substituting and calculating:
total flags = 12! / (5! 3! 4!)
total flags = 27,720
Therefore there are about 27,720 different 12-flags signals.

The graph shows the number of sprays an automatic air freshener dispenses, y, in x minutes
Which expression can be used to calculate the rate per minute at which the air freshener dispenses sprays?
fraction 30 over 2
fraction 2 over 30
fraction 30 over 8
fraction 8 over 30
the first dot is on 2 for number of sprays and 30 for time
so the expression would be number of sprays over time so 2 over 30
2/30 that would reduce to 1/15 meaning each spray happens every 15 minutes

What is the differnce between union and intersection in math
Final answer:
Union and intersection are two operations used in set theory to combine sets or find common elements.
Explanation:
Union and intersection are two operations used in set theory. In mathematics, a set is a collection of distinct objects. The union of two sets A and B, denoted by A ∪ B, is the set that contains all the elements that are in either A or B or in both. The intersection of two sets A and B, denoted by A ∩ B, is the set that contains all the elements that are common to both A and B.
For example, let's consider two sets: A = {1, 2, 3} and B = {2, 3, 4}. The union of A and B is {1, 2, 3, 4}, as it contains all the elements from both sets. The intersection of A and B is {2, 3}, as those are the elements that are common to both sets.

The perimeter of a rectangular slab of concrete is 24 meters. If the length of the
rectangular slab is 2 meters longer than its width, what is the width of the slab?
Answers:
A) 5 meters
B) 6 meters
C) 7 meters
D) 8 meters
The answer is 5 meters but i don't know how to get that. HELP
The width of the slab is 5 meters which is correct option(A).
What is perimeter of rectangle?Perimeter of rectangle is defined as addition the lengths of the rectangle's four sides.
Let length of slab is L, width is W,
The perimeter of a rectangular slab = 24
2(length) + 2(width) = 2L + 2W = 24
If the length of the rectangular slab is 2 meters longer than its width
= width + 2
So, the equation L = W+2
Now substitute, L= W+2 in equatioin of perimeter,
2(W+2) + 2W = 24
2W + 4 + 2W = 24
4W = 24-4 = 20
W = 20/4 = 5
W = 5
Hence, the width of the slab is 5 meters.

Which of the following show the factored equivalent of f(x) = (2x2 +7x + 3)(x - 3) and its zeros?
f(x) = (x + 5)(x + 7)(x - 3); -5, -7, 3
f(x) = (x + 3)(2x + 1)(x - 3); -3, -0.5, 3
f(x) = (x + 5)(x + 7)(x - 3); 5, 7, -3
f(x) = (x + 3)(2x + 1)(x - 3); 3, 0.5, -3
Final answer:
The factored equivalent of [tex]f(x) = (2x^2 +7x + 3)(x - 3)[/tex] is f(x) = (x + 3)(2x + 1)(x - 3), and its zeros are -3, -0.5, and 3.
Explanation:
The factored equivalent of the polynomial f(x) = (2x2 +7x + 3)(x - 3) and its zeros can be determined by factoring [tex]2x^2 + 7x + 3[/tex]. We notice that this quadratic can be factored into (2x + 1)(x + 3). Therefore, when we include the (x - 3) term, we get the fully factored form,
f(x) = (2x + 1)(x + 3)(x - 3). To find the zeros, we set each factor equal to zero:
2x + 1 = 0 gives a zero of -0.5;
x + 3 = 0 gives a zero of -3; and,
x - 3 = 0 gives a zero of 3. Thus, the correct answer is
f(x) = (x + 3)(2x + 1)(x - 3); -3, -0.5, 3.

Use the remainder theorem to determine the remainder when d4 + 2d2 + 5d − 10 is divided by d + 4. A. 42 B. 258 C. 126 D. 106
Answer: The correct option is (B) 258.
Step-by-step explanation: We are give to use the remainder theorem to determine the remainder when
[tex]d^4+2d^2+5d-10[/tex] is divided by [tex]d+4.[/tex]
Remainder Theorem : If p(x) is a polynomial in x and a is any real number, then the remainder when p(x) is divided by (x - a) is p(a).
For the given division, we have
[tex]p(d)=d^4+2d^2+5d-10\\\\d-a=d+4~~~~~\Rightarrow a=-4.[/tex]
Therefore, the remainder when p(d) is divided by (d + 4) is given by
[tex]p(-4)\\\\=(-4)^4+2\times (-4)^2+5\times(-4)-10\\\\=256+32-20-10\\\\=288-30\\\\=258.[/tex]
Thus, the required remainder is 258.

In what direction and by how many units is the graph of f(x) = 6 sin(2x + π) − 5 vertically and horizontally shifted?
Down 5, left pi over 2
Up 5, left pi over 2
Down 5, right pi over 2
Up 5, right pi over 2
Answer:
Option 1 is correct.
Step-by-step explanation:
Given graph of f(x)=6 sin(2x + π) - 5
we have to tell in what direction the graph vertically and horizontally shifted.
As, f(x+1) is a change on the inside of function, giving a horizontal shift left by 1, and the subtraction by 3 in f(x+1)-3 is a change to the outside of function, giving a vertical shift down by 3.
Hence, the graph of f(x)=6sin(2x + π) - 5
Here, change on the inside of function, giving a horizontal shift left by [tex]\frac{\pi}{2}[/tex], and subtraction by 5 in function is a change to the outside of function, giving a vertical shift down by 5.
Option 1 is correct.
