Answer:
5i, and - 5i ⇒ ± 5i
Step-by-step explanation:
We are given the equation 2x^2 + 16 + 34 = 0;
2x^2 + 16 + 34 = 0 ⇒ subtract ( 16 + 34 ) from either side of equation,
2x^2 = - 50 ⇒ divide either side by 2,
x^2 = - 25 ⇒ take square root on either side of equation,
| x | = √ - 25 ⇒ apply imaginary value i,
± 5i, provided absolute value sign | |;
Solution; ± 5i

The ordered pairs (12, 32), (x, 40), (18, 48), (21, y) represent a proportional relationship. Find the values of x and y. Select the two correct answers.
x = 14
x = 15
x = 17
y = 62
y = 56
y = 78
Answer:
This is the closest thing I could get
x=15
Y=56
Step-by-step explanation:
The difference between 32 and 12 is 20
So the difference between x and 40 is 25
Between 48 and 18 its 30
And last between 21 and y is 35

Answer:
<1 = 112
Step-by-step explanation:
<1 and <2 form a straight line so they add to 180 degrees
3x+22 + 2x+8 = 180
Combine like terms
5x + 30 = 180
Subtract 30 from each side
5x+30-30 = 180-30
5x = 150
Divide each side by 5
5x/5 = 150/5
x = 30
We want to find <1
3x+22
3*30 +22
90+22

An observer (0) spots a plane flying at a 55° angle to his horizontal line of sight. If the plane is flying at an altitude of 21,000 ft., what is the distance (x)
from the plane (P) to the observer (O)? (4 points)
A)20,793 ft
B)28,793 ft
C)36,585 ft
D)25,636 ft
Answer:
Option D. 25636 ft
Step-by-step explanation:
From the given right triangle,
Observer is at the point O and he observes the plane flying at point P.
Angel of elevation of the plane is 55° and altitude of the plane was 21000 ft.
To get the distance OP we will apply Sine rule in the given right triangle,
Sin 55 = [tex]\frac{h}{x}[/tex]
Sin 55 = [tex]\frac{21000}{x}[/tex]
x = [tex]\frac{21000}{\text{sin}55}[/tex]
x = 25636.27
x ≈ 25636 ft
Therefore, distance between the plane and observer is 25636 ft.
Option D. is the answer
Answer:
Option D. 25636 ft

Find the value of y. Use 3.14 for pie
Answer:11
Step-by-step explanation: Again, you have to write the expression. In this case, it would be 3.14x(9.3x9.3)xY=3000. If you simplify, it would be 3.14x86.49xY=3000. You would than multiply 3.14 and 86.49, and it would be about 271. Then, you divide 3000 with 271, and it would be about 11 if you round to the nearest whole number
Explain why 3/4 of 16 is the same as 3 x 16 divided by 4
Please Help
Answer:
I know that 3/4 is 75%, and I also know that 3 times 16 is 48. Since I divide 48 by 4, it is the same as multiplying 4 by 3, knowing that it is 25% of 16.
Step-by-step explanation:
Since 3/4 is a fraction, all fractions can be converted into decimals.
3/4 is also known as 75%, which can be simplified into 0.75 in decimal terms.
Now that you know that 3/4 can be simplified to 0.75, you now need to take that 0.75, and multiply it by 16. You can use a calculator to do this, or you could work it out on a sheet of paper.
An easy way to do this, is to know that 25%, (0.25) of 16 is 4. This is because 4 times 4 is 16. Knowing this, if you are looking for 75% of 16, (0.75) you can multiply 4 by 3, knowing that it is 75% of 16.
The answer to that is 12.
3 x 16 = 48 and if you take 48 and divide it by 4, you will get 12.
You can explain this by writing; I know that 3/4 is 75%, and I also know that 3 times 16 is 48. Since I divide 48 by 4, it is the same as multiplying 4 by 3, knowing that it is 25% of 16.

Find the perimeter of the square.
64 ft
16 ft
8 ft
32 ft
Answer:
32 ft
Step-by-step explanation:
The perimeter is basically the area of the outside of a shape. To calculate this, you would add up all the sides together and get the answer.
8 + 8 + 8 + 8=32 or you can just do 8*4 which is also 32
So, the answer is 32

You increase the lengths of the sides of a cube by the factor 2. What is the ratio of the new cube to the original.
a. 8:1
b. 4:1
c. 1:2
d. 2:1
Answer:
Answer a (8:1)
Step-by-step explanation:
Surface area or volume?
I will assume it's volume.
The volume formula is V = s^3, where s is the length of one side of the cube. If we double s, we get V2 = (2s)^3, or 8s^3, which is 8 times greater than thevolume of the cube with side length s.
The ratio is then 8s^3/s^3 or 8/1 or 8:1.

Answer:
y = 3[tex]\sqrt{2}[/tex] + 4
Step-by-step explanation:
Create 2 equations using values from the table to find a and b.
Using (0, 10), then
10 = acos0° + b ( cos0° = 1 ), thus
a + b = 10 → (1)
Using (90, 4), then
4 = acos90° + b ( cos90° = 0 ), thus
b = 4
Substitute b = 4 into (1)
a + 4 = 10 ( subtract 4 from both sides )
a = 6
Thus
y = 6cosx° + 4
When x = 45°, then
y = 6cos45° + 4 = 6 × [tex]\frac{\sqrt{2} }{2}[/tex] + 4 = 3[tex]\sqrt{2}[/tex] + 4
Answer:
y = 3\sqrt{2} + 4

Step-by-step explanation:
If you put the 24 in the place of the place of the x, the answer is 12.
I could be wrong, but I'm pretty sure that's how you do it.
Answer:
C. 12
Step-by-step explanation:
The input in an expression are the factors that are multiplied, added, divided, etc. together to get an answer (output).
In x/2, the input is 24, and it will replace x.
so 24/2 = 12.

Find the circumference of the object.
Answer:
43.96 in
Step-by-step explanation:
From the diagram we know that the radius of the circle is 7 in.
The formula for the circumference is C = 2(pi)(r).
Substituting 3.14 for pi and 7 in. for r, we get the final result, the circumference:
C = 2(3.14)(7 in) = 43.96 in
