Answer:
the answer to this question is 19
Answer: m=19
Step-by-step explanation:
First you cross multiply the two fractions. So you get 9*m = 57*3.
When you put 57*3 in a calculator you get 171. So the equation is 9m=171 and then to isolate the x you divide by 9. So when you put 171/9 in a calculator you get 19. So the correct answer is C. 19.

Rewrite the problem in terms of some using the double-angle formula.
Answer:
sin2x = √3/2.
Step-by-step explanation:
sin2x = 2 sinx cosx
So sinx cosx = 1/2 sin2x
So 1/2 sin2x = √3/4
sin2x = √3/4 * 2
sin2x = √3/2.

Answer:
Step-by-step explanation:
Answer:
(-2, -11)
(0, -1)
(2, 9)
(4, 19)
Step-by-step explanation:
when x = -2:
⇒ y = 5(-2) - 1
⇒ y = -10 - 1
⇒ y = -11
when x = 0:
⇒ y = 5(0) - 1
⇒ y = 0 - 1
⇒ y = -1
when x = 2:
⇒ y = 5(2) - 1
⇒ y = 10 - 1
⇒ y = 9
when x = 4:
⇒ y = 5(4) - 1
⇒ y = 20 - 1
⇒ y = 19

I just typed it in the calculator graph and scrolled down past the errors
The coordinates of point A on a grid are (−2, −4). Point A is reflected across the y-axis to obtain point B. The coordinates of point B are (, −4).
The coordinates of the point B are given as (2, - 4)
What is coordinate geometry?A coordinate plane is a 2D plane which is formed by the intersection of two perpendicular lines known as the x-axis and y-axis.
Under a reflection in the y- axis
A point (x, y) → (- x, y), hence
A(- 2, - 4) → B(2, - 4)
Therefore the coordinates of the point B are given as (2, - 4)

When Nabhitha goes bowling, her scores are normally distributed with a mean of 115
and a standard deviation of 11. What percentage of the games that Nabhitha bowls
does she score between 93 and 142, to the nearest tenth?
Statistics Calculator
Answer:
By the Empirical Rule, in 99.7% of the games that Aubree bowls she scores between 148 and 232Step-by-step explanation:The Empirical Rule states that, for a normally distributed random variable:68% of the measures are within 1 standard deviation of the mean.95% of the measures are within 2 standard deviation of the mean.99.7% of the measures are within 3 standard deviations of the mean.In this problem, we have that:Mean = 190Standard deviation = 14Using the empirical rule, what percentage of the games that Aubree bowls does she score between 148 and 232?148 = 190 - 3*14So 148 is 3 standard deviations below the mean.232 = 190 + 3*14So 232 is 3 standard deviations above the meanBy the Empirical Rule, in 99.7% of the games that Aubree bowls she scores between 148 and 232

Brooke is located 5 miles out from the nearest point A along a straight shoreline in her sea kayak. Hunger strikes and she wants to make it to Kono's for lunch; see picture. Brooke can paddle 7 mph and walk 14 mp
If she paddles along a straight line course to the shore, find an expression that computes the total time to reach lunch in terms of the location where Brooke beaches her kayak (so x = distance from A to where she lands). Be sure you remember the formula that relates Distance, Rate and Time. You're being asked for Time here
If she paddles directly to Kono's then the minimum time for the lunch will be 3.9 hours.
What is kinematics?It is the study of the motion of a body without considering mass. And the reason behind them is neglected.
Brooke is located 5 miles out from the nearest point A along a straight shoreline in her sea kayak.
Hunger strikes and she wants to make it to Kono's for lunch; see picture.
Brooke can paddle at 7 mph and walk at 14 mph.
Distance from Brooke to shore will be
→ √(5² + x²)
Then the time will be
[tex]t_1 = \dfrac{\sqrt{5^2 + x^2}}{2}[/tex]
Then the distance from shore to Kono's will be
→ 6 - x
Then the time will be
t₂ = (6 - x) / 4
Then the total time will be
t = t₁ + t₂
Then we have
[tex]t = \dfrac{\sqrt{5^2 +X^2}}{2} + \dfrac{6-x}{4}\\[/tex]
t = 1/4[2√(5² + x²) + 6 - x]
If she paddles directly to point A will be
t = 1/4[2√(5² + 0²) + 6 - 0]
t = 1/4 (10 + 6)
t = 16 /4
t = 4 hr
If she paddles directly to Kono's, then we have x = 6. Then the time will be
t = 1/4[2√(5² + 6²) + 6 - 6]
t = 1/4[2√61]
t = 3.9 hr

We can evaluate the mean, median, standard deviation and many other statistical measures from the stem-leaf table.
What is mean?It is defined as the single number that represents the mean value for the given set of data or the closed value for each entry given in the set of data.
From the stem leaf table, we can find different statistical measures.
From the picture attached, we can find different data
The minimum value = 12
The maximum value = 49
Total number of observation = 30
The sum of the all data = 986
Mean of the data = 986/30 = 32.87
Median of the data = 34.5

A furniture shop produces two types of custom made chairs. If the price of one type of chair is three times the price of the other, and the total price for both is $15365, what is the price of other chair?
Answer:
The price of other chair is $3841.25
Step-by-step explanation:
Step 1: Write equations.
First equation: The price of one type of chair is three times the price of the other.
Let x be the price of one type of chair and y the price of the other type of chair.
[tex]x = 3y[/tex]
Second equation: The total price for both is $15365
[tex]x + y = 15365[/tex]
Step 2: Solve the system of equations.
1) [tex]x = 3y[/tex]
2) [tex]x + y = 15365[/tex]
Substitute x in the second equation with x from first.
[tex]x + y = 15365\\(3y) + y = 15365[/tex]
Now solve for y (y is the price of the other chair).
[tex]4y = 15365\\y = \frac{15365}{4}\\y = \$3841.25[/tex]
If r=1 and 0=5pie/3, what is the approximate arc length?
Answer:
5.236 units
Step-by-step explanation:
The relation between r, θ and arc length ( l ) is,
l = rθ
l = 1 * 5π / 3
( The value of π = 3.14 approximately )
5π = 5 x 3.14 = 15.7
l = 1 * 5π / 3
= 5π / 3
= 15.7/3
l = 5.236 units

Points O, C, and P are collinear with O(−10, −8) and P(−2,8). Point C divides the line segment OP into the ratio 3: 5. What are the coordinates of point C?
Using proportions, it is found that the coordinates of point C are given as follows: C(-7, -2).
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
Point C divides the line segment OP into the ratio 3:5, hence the following equation is used to relate the points:
[tex]C - O = \frac{3}{8}(P - O)[/tex]
Then, for the x-coordinate:
[tex]x + 10 = \frac{3}{8}(-2 + 10)[/tex]
x + 10 = 3
x = -7
For the y-coordinate:
[tex]y + 8 = \frac{3}{8}(8 + 8)[/tex]
y + 8 = 6
y = -2

Find the equation of the line that passes points
A(1,7)B(-3,-1)
Answer:
y = 2x + 5
Step-by-step explanation:
Here we have the two points as (x1=1, y1=7) and (x2 = -3, y2 = -1)
Slope of this line = (y2-y1)/(x2-x1) = (-1 -7)/(-3 - 1) = 8/4 = 2
Using slope intercept form of y = mx + c
we get y = 2 x + c
Substituing the coordinates (1,7) in this equation gives us
7 = 2.1 + c or c =5
hence y = 2x + 5
Check
if x = -3 then y = (-2)(-3) + 5 = -6 + 5 = -1 which satisfies the coordinates for the second point
