Answer:
sin = -√3/2cos = -1/2tan = √3sec = -2csc = (-2/3)√3cot = (√3)/3Step-by-step explanation:
See the attached picture for a drawing of the angle and its terminal point coordinates. Those are (cos(4π/3), sin(4π/3)), so we have the following trig function values:
sin(4π/3) = -√3/2
cos(4π/3) = -1/2
tan(4π/3) = sin/cos = √3
sec(4π/3) = 1/cos = -2
csc(4π/3) = 1/sin = -(2√3)/3
cot(4π/3) = 1/tan = (√3)/3

Additional comment
It helps to know that 1/√a = (√a)/a. This lets you write the ratios with a rational denominator in each case.

2. In the number shown, one digit is underlined and one digit is circled. Which statement about the circled digit is true?
Its value is 10 times greater than the value of the underlined digit.
Its value is 1/10 the value of the underlined digit.
Its value is 70 times the value of the underlined digit.
Its value is 1/70 the value of the underlined digit.
See attachment below for the number
Step-by-step explanation:
This problem is about the place value of whole numbers.
Step 1: Determining the place value of the numbers
The place value is the value of each digit in a number, be it a whole number or a decimal number.
The number shown is seventy seven thousand (77,000)
The place value of the underlined 7 is 7 ten thousands = 7 * 10000 = 70000
The place value of the circled 7 is 7 thousands = 7 * 1000 = 7000
Step 2: Comparing the numbers
Comparing the circled number and the underlined number:
7000/70000 = 1/10
Therefore, the correct option is: Its value is 1/10 the value of the underlined digit.
7. During a person's commute to school, she spends 10 minutes driving 30 miles per hour (mph) and 5 minutes stopped at red lights. (a) (1 pt.) Find the distance of her commute.
Answer:
Total distance = 5 miles
Step-by-step explanation:
Given:
Total time for drive = 10 min = 10 / 60 = 1/6 hour
Time for stop = 5 min
Speed = 30 miles pr hour
Find:
Total distance
Computation:
Total distance = Speed × time
Total distance = 30 × (1/6)
Total distance = 5 miles
Solve for x.
-3x = 15
X= -5
X= 5
X= 45
Caculate the unit rate using the following
information, mom drove 20 miles in 1/4 of an hour
What was her rate or spee in Miles per hour.
Answer:
80 miles per hour
Step-by-step explanation:
To find her speed in miles per hour, multiply 20 by 4.
Since she drove 20 miles in 1/4 of an hour, we can find the amount she can drive in 1 full hour by multiplying it by 4.
20(4)
= 80
So, her rate in miles per hour is 80 miles per hour
Answer:
80 mph
Step-by-step explanation:
20 miles multiplied by 4(quarters of the hour) is 80mph
a helicopter is 14 meters above a canyon it goes down 20 meters then up 5 write a subtraction sentence, how do you know your answer is correct?
Answer:
14 - 20 + 5
14 - 15 = -1
-1
If you take 14 meters and you go down 20 meters that is 14 - 20
Then, if you go up 5 meters, that is 14 - 20 + 5.
So simplify 14 - 20 + 5.
Simplified: 14 - 15
So the answer is -1 meter

Question 7 of 10
If h(x) = (fºg)(x) and h(x) = Vx+5, find g(x) if f(x) = (x+2.
Answer here
Answer:
g(x) = x + 3
Step-by-step explanation:
A composite function is a function that is written inside another function which means substituting one function into another function.
Ex: (fоg)(x) is a composite function, where x of f(x) is substituted by g(x)
∵ h(x) = (fоg)(x)
∵ [tex]h(x)=\sqrt{x+5}[/tex]
∵ [tex]f(x)=\sqrt{x+2}[/tex]
→ Substitute x of f(x) by g(x)
∴ (fоg)(x) = [tex]\sqrt{g(x)+2}[/tex]
→ Equate (fоg)(x) by h(x)
∴ [tex]\sqrt{g(x)+2}=\sqrt{x+5}[/tex]
→ Cancel the roots from the two sides
∴ g(x) + 2 = x + 5
→ Subtract 2 from both sides
∴ g(x) + 2 - 2 = x + 5 - 2
∴ g(x) = x + 3

v/8= 2
Step-by-step explanation:
v/8=2
v=8×2
v=16
16/8=2
Answer:
v = 16
Step-by-step explanation:
v/8 =2
Lets isolate v.
Multiply 8 on both sides.
v = 16
This is a one step equation, so there isn't realy that much to it.
Put this equation into slope- intercept form. -2x + 3y = 9
Answer:
y = 2/3x + 3
Step-by-step explanation:
In order to put it in slope intercept form (y = mx + b), y needs to be isolated.
Add 2x to both sides:
-2x + 3y = 9
3y = 2x + 9
Then, divide both sides of the equation by 3.
3y = 2x + 9
y = 2/3x + 3 is the equation in slope intercept form
Answer:
Slope-intercept form:
→ y = (2/3)x + 3
Step-by-step explanation:
Given equation,
→ -2x + 3y = 9
Now we have to,
→ Convert this given equation into the slope-intercept form.
The slope-intercept form is,
→ y = mx + b
Let's convert the equation,
→ -2x + 3y = 9
→ 3y = 9 + 2x
→ 3y = 2x + 9
→ y = (2x + 9)/3
→ y = (2x/3) + (9/3)
→ y = (2/3)x + 3
From this slope-intercept form:
→ Slope (m) = 2/3
→ y-intercept (b) = 3
Thus, the answer is y = (2/3)x + 3.

A line contains the points (6, 8) and (1,-2).
What is the slope of the line in simplified form?
Enter your answer in the box
Answer:
The slope of the line is two.
Step-by-step explanation:
Recall that to find the slope between any two points, we can use the slope formula:
[tex]\displaystyle m = \frac{y_2-y_1}{x_2-x_1}[/tex]
Let (6, 8) be our (x₁, y₁) and let (1, -2) be our (x₂, y₂). Substitution yields:
[tex]\displaystyle m=\frac{(-2)-(8)}{(1)-(6)}[/tex]
Subtract:
[tex]\displaystyle m=\frac{-10}{-5}[/tex]
Divide:
[tex]m=2[/tex]
Therefore, the slope of the line is two.
