find f ( x ) g ( x )
Select one:
a. 12i + 3i
b. 11
c. 4i - 3i
d. 4 + 12i
Answer:
[tex]f(x)g(x) = (3 - i)(4i) \\ = 12i - 4 {i}^{2} \\ = \boxed{12i + 4 }\\ remember \:the \: value \: of \: {i}\: is \: \sqrt{ - 1} \\ and \: {i}^{2} \: is - 1 \\ d. (4 + 12i)\: is \: the \: right \: answer.[/tex]
Write sin (4theta) in terms of sin (2theta) and cos (2theta).
Answer:
2 sin 2 theta cos 2 theta
Step-by-step explanation:
Mathematically;
sin (4theta) = sin (2theta + 2theta)
Using the sine addition rule
That would be;
sin 2 theta cos 2 theta + sin 2 theta cos 2 theta
= 2 sin 2 theta cos 2 theta

Answer:
Y = 10.25 or 10.247
Step-by-step explanation:
Alright So use the Formula A^2 + B^2 = C^2
You have one leg and the hypotenuse so first you are going to find 19 ^2 = 361.
Next, you need to find 16^2 = 256.
Last but not least, you subtract the leg from the hypotenuse, which equals 361-256=105
Finally, you take 105 and find its square root.
And depending on how far you round it down, your answer would be 10.25(that is in tenths), or 10.247(which is rounded to hundredths)

A large bag of chocolate chips contains 11 1 4 cups. A cookie recipe needs 1 1 2 cups of chocolate chips. How many times can the cookie recipe be made? .
Answer: 7 1/2
Step-by-step explanation:
From the question, we are informed that a large bag of chocolate chips contains 11 1/4 cups and that a cookie recipe needs 1 1/2 cups of chocolate chips.
The number of times that the cookie recipe can be made will be:
= 11 1/4 ÷ 1 1/2
= 45/4 ÷ 3/2
= 45/4 × 2/3
= 7 1/2
The recipe can be made 7 1/2 times

Answer:
The answer ia option 2
Step-by-step explanation:
When a line is parallel to the other line, they will have the same slope (gradient).
The new equation will be y = (1/4)x + b.
Next, you have to find the value of b, by substituting the coordinates into the equation :
[tex]y = \frac{1}{4} x + b[/tex]
[tex]let \: x = - 4,y = - 2[/tex]
[tex] - 2 = \frac{1}{4} ( - 4) + b[/tex]
[tex] - 2 = - 1 + b[/tex]
[tex]b = - 1[/tex]

Answer:
103 to 107 is (2). 108 to 112 is (4). 113 to 117 is (2)
Step-by-step explanation:
find the angle p (add a explanation too)
Step 1: Find the sum of the interior angles
Use this formula: 180 x (n - 2)
n is the number of sides of the polygon
Work:
180 x (4 - 2)
180 x 2
360
Step 2: Find the angle right above the 94 degree angle
The entire angle (a circle) is equal to 360 degrees. To find the part we're looking for (inside of the polygon), we need to subtract the angle we already know from 360.
Work:
360 - 94
266
Step 3: Set up an equation to find the missing angle p
We now know every angle except p! And we know the sum of the interior angles. Knowing this information makes it really easy to set up an equation.
360 = 12 + 75 + 266 + p
360 = 353 + p
p = 7 degrees
Does this answer make sense?
Yes! Although the drawing may not be to scale, it is very possible that angle p could be 7 degrees because of how 12 degrees looks on this graph.

Write an equation in slope-intercept form for the line that has a slope of 12 and passes through the point (3, 20).
Answer:
Step-by-step explanation:
It's a simple question as we know:
y-y1=m(x-x1)
y-20=12(x-3)
y=12x-36+20
y=12x-16
Now, your line is in slope intercept form you can compare it with
y=mx+c
m=12 and c=16. You can also put your point to verify your answer.
Solve for x: x - 2 > 2x + 12.
Ox> 14
0x< 14
Ox>-14
Ox<-14
Answer:
Solving the inequality: [tex]x - 2 > 2x + 12[/tex] we found the value of x: [tex]\mathbf{x<-14}[/tex]
Option D is correct option.
Step-by-step explanation:
We need to solve the inequality: [tex]x - 2 > 2x + 12[/tex] and find value of x
Solving the inequality
[tex]x - 2 > 2x + 12[/tex]
First of all, we will add 2 on both sides
[tex]x - 2+2 > 2x +12 +2\\x>2x+14[/tex]
Now, add -2x on both sides of inequality
[tex]x-2x>2x+14-2x\\-x>14[/tex]
Now, multiply both sides by -1, when multiplying by negative number, the inequality is reversed i.e. > will become <
[tex]-1*-x<14*-1\\x<-14[/tex]
So, solving the inequality: [tex]x - 2 > 2x + 12[/tex] we found the value of x: [tex]\mathbf{x<-14}[/tex]
Option D is correct option.

Answer:
-2/x
Step-by-step explanation:
simplified is y = -x/2 - 6
Perpendicular slopes are just reciprocals of the original slope, so just flipp the original slope around to be the complete opposite.
Example if slope= -2, the reciprocal= -1/2
Just flip the numerator with the denominator for perpendicular slope

An aircraft flies at a speed of 480 miles per hour. It takes the aircraft t hours to reach its destination.
Which of the following equations can be used to find the number of hours it takes the aircraft to reach a destination that is 1200
miles away?
A 1200t=480
B480+1200=t
C480t=1200
D 480+t=1200
Answer:
A
Step-by-step explanation:
The equation 480t = 1200 can be used to find the number of hours an aircraft takes to reach a destination that is 1200 miles away.
The correct answer is option (C) 480t = 1200.
What is equation?"An equation is a mathematical statement that is made up of two expressions connected by an equal sign."
Formula to calculate speed:speed = distance / time
For given question,
An aircraft flies at a speed of 480 miles per hour and takes t hours to reach its destination.
Let d represents the distance(in miles) traveled by an aircraft in t hours with a speed of 480 miles per hour.
By using the formula of speed,
⇒ 480 = d/t
When destination is 1200 miles away.
This means d = 1200 miles.
⇒ 480 = 1200/t
⇒ 480t = 1200 .....................(Multiplying both the sides by t)
This equation can be used to find the number of hours it takes the aircraft to reach a destination that is 1200 miles away.
Therefore, option (C) is the correct answer.
