Answer:
q = 4.9
m∠R = 27.1°
m∠S = 136.9°
Step-by-step explanation:
To solve the triangle we will use the cosine rule and the sine rule
In the given triangle
∵ q is the opposite side of ∠Q
∵ s is the opposite side of ∠S
∵ r is the opposite side of ∠R
∵ m∠Q = 16°
∵ r = 8 and s = 12
→ By using the cosine rule to find q
∴ q² = r² + s² - 2 r s cos∠Q
→ Substitute the values of r, s, and ∠Q in the rule above
∵ q² = (8)² + (12)² - 2(8)(12)cos(16°)
∴ q² = 23.43775438
→ Take √ for both sides
∴ q = 4.841255455
→ Round it to the nearest tenth
∴ q = 4.9
→ To find angles R and S we will use the sine rule
∵ [tex]\frac{r}{sin(R)}[/tex] =[tex]\frac{q}{sin(Q)}[/tex] = [tex]\frac{s}{sin(S)}[/tex]
→ Use the first two ratios to find m∠R
∵ [tex]\frac{8}{sin(R)}[/tex] = [tex]\frac{4.841255455}{sin(16)}[/tex]
→ By using cross multiplication
∴ 4.841255455 × sin(R) = 8 × sin(16)
→ Divide both sides by 4.841255455
∴ sin(R) = 0.4554807874
→ Use [tex]sin^{-1}[/tex] to find m∠R
∵ m∠R = [tex]sin^{-1}[/tex] (0.4554807874)
∴ m∠R = 27.0958732
→ Round it to the nearest tenth
∴ m∠R = 27.1°
∵ The sum of the measures of the angle in a triangle is 180°
∴ m∠S + m∠Q + m∠R = 180°
→ Substitute the values of m∠Q and m∠R
∵ m∠S + 16° + 27.1° = 180°
∴ m∠S + 43.1 = 180
→ Subtract 43.1 from both sides
∴ m∠S = 136.9°

Find the range of the graphed function.
A. Y is all real numbers
B. Y>_0
C. 0<_y<_10
D. -9<_y<_5
Btw, <_ or >_ is the greater than or equal to or less than or equal to sign.
Answer:
The range of the function should be:
-9 ≤ y ≤ 5
Hence, option D is true.
Step-by-step explanation:
We know that the set of values of the dependent variable for which a function is defined.
From the given function, we can easily observe that the graph is kind of oscillating between the y-value y = 5 and y = -9.
i.e.
at y = 5, the graph gets its maximum value
at y = -9, the graph gets its minimum value
Thus, the range of the function should be:
-9 ≤ y ≤ 5
Hence, option D is true.

Total consumption of fruit juice in a particular country in 2006 was about 2.05 billion gallons. The population of that country in 2006 was 500 million. What was the average number of gallons of fruit juice consumed per person in the country in 2006?
Answer:
4.1 gallons per person
Step-by-step explanation:
The total consumption of fruit juice is 2.05 billion
The total population is 500 million
Therefore the average number of gallons fruit juice consumed per person can be calculated as follows
=total consumption/total population
= 2,050,000,000/500,000,000
= 4.1 gallons per person

Which of the following best describes the graph above?
OA. both a relation and a function
OB. function only
OC. neither a relation nor a function
OD. relation only
Answer:
The answer you are looking for is B) Function only.
Step-by-step explanation:
A function graph would mean that each x value corresponds to one y value, in a function multiple x values can have the same output but one x value cannot have more than one output.
A relative graph means each x value has their own unique output value and each x value (f(x)) has one output but cannot share that output with any other x value.
In this case x=5 which means it can only be a function.

Write an equation in slope-intercept form of the line shown.
(2,-1) (4,-4)
Answer:
add 44 and 21 and you will get the answer
Answer:
y = -3/2x+2
Step-by-step explanation:
The slope for a slope equation is y = mx+b
Since it's decreasing from left to right the first part of the equation (mx) is -#x. The second part of the equation (+b) will be +2 because the y-intercept is (0,2). If it were a negative # then it would be -7, or -4, or - whatever.
Now you have to find the slope. To find the slope simply do y1-y2/x1-x2 or y2-y1/x2-x1. Let's follow this equation. say that (2,-1) is 1 and (4,-4) is 2.
-1+4/2-4 = 3/-2 = -3/2. The equation would be y = -3/2x +2. Let's check our work by substituting our variables with numbers using the set (2,-1). Pleases tell me if I'm wrong or if this is confusing.
2. Find the value of x.
Answer:
x = 3
Step-by-step explanation:
You can see that 5x - 7 and 2x + 2 are equal to each other due to the arrows pointing to both angles. Therefore allowing you to set up the following equation..
5x - 7 = 2x = 2
Therefore you can then simplify for the value x where you should get teh value 3.

Answer:
5.5
Step-by-step explanation:
Miranda mixes 34.5 fluid ounces of blue paint
40.5 fluid ounces of red paint.
2 fluid ounces of black paint to produce a purple paint
She pours this purple paint into 14 jars
Therefore the amount of paint in each jar can be calculated as follows
= 34.5 + 40.5 + 2
= 77/14
= 5.5 fluid ounces
Hence there are 5.5 fluid ounces of purple paint in each jar

Answer:
x = 4
y = -7 or (-7, 4)
Step-by-step explanation:
y = -2x + 1
4x + y = 9 replace y in the second equation with (-2x + 1) since y is equal to it
4x + (-2x + 1) = 9 add like terms
2x + 1 = 9 subtract 1 from both sides
2x = 8 divide both sides by 2
x = 4 since y = -2x + 1 replace x with the value we found
y = (-2) × 4 + 1 = -7
