Express the following in the form a + bi, where a and b are real numbers:
[tex] \sqrt{60i - 11} [/tex]
The equivalent of the complex number expression is [tex]\sqrt{60i - 11}[/tex] is 2 + 15i
How to rewrite the expression?The complex number expression is given as:
[tex]\sqrt{60i - 11}[/tex]
Rewrite as:
[tex]a + bi = \sqrt{60i - 11}[/tex]
Take the square of both sides
[tex]a^2 + 2abi - b = 60i - 11[/tex]
By comparison, we have:
a^2 - b = -11
2ab = 60
Divide both sides by 2
ab = 30
Using a graphical tool, we have:
a = 2,b = 15
So, we have:
a + bi = 2 + 15i

What is the value of x?
Answer:
x = 80 degrees
Step-by-step explanation:
First look at the upper triangle. There are two 65 degree angles there, along with two equal sides. The angles must sum up to 180 degrees. Therefore:
2(65) + x = 180; thus, the value of x is 50 degrees.
Next, recognize that the vertical angles in the middle of the diagram are equal and are 50 degrees each. Thus, the smaller triangle has two 50-degree angles. Again we sum up the angles, obtaining 50 + 50 + x = 180, or x = 80 degrees
An apple-juice container has a tiny hole in it, so it is slowly leaking. If the container leaks three
ounces every 19 minutes, how long will it take for the 16 ounces of juice in the container to leak
out? Write a proportional equation and solve with J.R.'s strategy of using a Giant One. 3 id
14
Answer:
101.33333 minutes
Step-by-step explanation:
Given :
Leakage rate = 3 ounces per 19 minutes
Time it'll take for 16 ounces of juice in the container to leak out
The leakage rate on ounce per minute :
3 ounces / 19 minutes = 0.1578947 ounce per min
1f 0.1578947 ounces leak out in 1 minutes
16 ounces will leak out in x minutes
Hence ;
0.1578947x = 16 ounces
x = 16 / 0.1578947
x = 101.33335 minutes
OR :
3 ounces = 19 minutes
1 ounce = (19 / 3) = 6.333333 minutes
16 ounces = (15 + 1) ounce
15 ounces = 3 * 5
Hence, 15 ounces will leak in (19 minutes * 5) = 95 minutes
1 ounce = 6.33333 minutes
Hence,
16 ounces will leak in (95 minutes + 6.33333 ounces) = 101.33333 minutes
HENCE, All 16 ounces will leak out in 101.33333 minutes

Answer:
x = 14
Step-by-step explanation:
arc JL = 180° ( JL is a diameter ), then
arc KL = 180° - 31° = 149° , so
9x + 23 = 149 ( subtract 23 from both sides )
9x = 126 ( divide both sides by 9 )
x = 14
Answer:
X=14
Step-by-step explanation:
360-31-31=298
298/2=149
149-23=126
126/9=14
Bernice uses the equation C = 2h + 8 to find the total cost, C, in dollars, of renting a boat for h hours. If Bernice does not spend more than $32, what is the maximum number of hours she can rent the boat?
a 8
b 12
c 20
d 22
Answer:
A
Step-by-step explanation:
Since she's not spending more than $32, the equation is 2h + 8 ≤ 32.
Isolate h to find the maximum number of hours she can rent the boat:
2h + 8 ≤ 32
First, subtract 8 from both sides.
2h ≤ 16
Then divide both sides by 2.
h ≤ 8
h, the number of hours, must be less than or equal to 8, so 8 is the maximum number of hours Bernice can rent the boat for.
