Answer:
(7 -24√3)/50 = 0.14 -0.48√3
Step-by-step explanation:
Sine is negative and cosine is positive in the 4th quadrant, so ...
sin(α) = -√(1 -cos(α)²) = -√(1 -576/625) = -7/25
Then the cosine of the angle sum is ...
cos(α +5π/6) = cos(α)cos(5π/6) -sin(α)sin(5π/6)
= (24/25)(-√3/2) -(-7/25)(1/2)
= (7 -24√3)/50 = 0.14 -0.48√3

Answer:
decimal format = 29.25mixed number = 29 1/4Improper fraction = 117/4Step-by-step explanation:
Make the denominators equal after simplifying the denominators*. The denominators are currently 2 and 4. So you can just make your life easier by making the denominator of the first number a 4. Multiply both sides by 2.
1. Simplify
12*2+1 = 25/2
25/2*2/2 = 50/4
2. Simplify second number
16*4+3 = 67/4
3. Add the improper fractions
50/4 + 67/4 = 117/4
Total answer:29.25 = decimal formatmixed number = 29 1/4Improper fraction = 117/4Terms:

Sound travels approximately 12.3 miles per minute. How many minutes will
it take someone to hear thunder if it strikes 85 miles away? Round your
answer to the nearest tenths.
Answer:
6.9 minutes
Step-by-step explanation:
Setup equality:
[tex]\frac{12.3}{1} = \frac{85}{m}[/tex]
Cross multiply:
12.3m = 85
Divide both sides of equality by 12.3:
m = 6.9 minutes
It takes 6.9 minutes to take someone to hear thunder if it strikes 85 miles away.
What is Unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given:
Sound travels approximately 12.3 miles per minute.
So, if the thunder strikes 85 miles away it will take
=85/12.3
=6.91 minutes.
Hence, 6.91 minutes to take someone to hear thunder if it strikes 85 miles away.

Calculate the slope of a line that passes through the points (3, -20) and (5,8).
O 6
O4
O 14
O 26
Answer:
Option 3: 14 is the correct answer.
Step-by-step explanation:
Slope is denoted by m and is calculated using the formula:
[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
Here
(x1,y1) are the coordinates of first point and
(x2,y2) are the coordinates of second point
Given
(x1,y1) = (3, -20) and
(x2,y2) = (5,8)
Putting the values in the formula, we get
[tex]m = \frac{8-(-20)}{5-3}\\m = \frac{8+20}{2}\\m = \frac{28}{2}\\m = 14[/tex]
The slope of line passing through points (3, -20) and (5,8) is 14.
Hence,
Option 3: 14 is the correct answer.

What is a mathematical function, equation and expression?function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.equation modelling : Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis and results of the given problemGiven is that a baby is 18in long at birth and 27in long in ten months
At birth, the length of baby = 18 inches.
After 10 months, the length of the baby = 27 inches.
Increase in length per month will be -
r = (27 - 18)/(10 - 0)
r = 9/10
r = 0.9 inch
Therefore, the length of the baby will increase 0.9 inch per month.

If u= 1 + i and v= 1 - i, what is u + V?
Answer:
u + v = 2
Step-by-step explanation:
If v = 1 - i
and u = 1 + i
Then we have to calculate and value of u + v
Now u + v = ( 1 - i ) + ( 1 + i )
= (-i + i) + ( 1 + 1 ) [by adding like terms]
= 0 + 2
= 2

with work shown
Answer:
n=8
Step-by-step explanation:
3n=−8+4n
Simplify both sides of the equation.
3n=4n−8 (there isn't so It stays the same.
Subtract 4n from both sides.
3n−4n=4n−8−4n
−n=−8
Divide both sides by -1.
−n/-1 =−8/-1

The direct distance from Trevino to Lowell is 100 miles, and the direct distance from Lowell to Sun City is 30 miles. To the nearest mile, what is the direct distance from Las Palmas to Lowell?
Answer:
A. 55
Step-by-step explanation:
The direct distance from Las Palmas to Lowell = the altitude or height of the right triangle.
According to the right triangle altitude theorem, thus:
[tex] h = \sqrt{xy} [/tex]
Where,
h = direct distance from Las Palmas to Lowell = ?
x = direct distance from Trevino to Lowell = 100 miles
y = direct distance from Lowell to Sun City = 30 miles
Plug in the values into the equation
[tex] h = \sqrt{100*30} [/tex]
[tex] h = \sqrt{3,000} [/tex]
[tex] h = 55 miles [/tex] (nearest mile)
