Find the amplitude of the solution
y=-4sin1/3x
Answer:
c. 4
Step-by-step explanation:
The amplitude of a graph is basically the distance from the top of the wavelength to the bottom of the wave length. When dealing with the equation itself the amplitude is represented by the initial number being multiplied to the sin cos or tan. Since the amplitude is just the distance and direction does not matter, this value is always positive. Therefore, in this scenario, the amplitude would be 4.

Answer:
13 1/8 -9 6/7 = 3 15/56
Step-by-step explanation:
13 1/8 -9 6/7 = ?
convert to a common denominator:
56 works in this case
13 7/56 - 9 48/56 = ?
it's complicated to subtract 48/56 from 7/56 so let's convert 13 7/56 to 12 63/56
12 63/56 - 9 48/56 = 3 15/56
What are the solutions of the quadratic equation (x + 3)2 = 49? A. O x = 2 and x = - 10 B.O.x = 4 and x = -10 C.O x=-2 and x = -16 D.O x = 40 and x = -58
Answer:
B. x = 4 and x = -10
Step-by-step explanation:
First, expand the equation
(x + 3)² = 49
(x + 3)(x + 3) = 49
x² + 6x + 9 = 49
Subtract 49 from both sides
x² + 6x -40 = 0
Factor
(x + 10)(x - 4) = 0
Solve
x + 10 = 0
x = -10
x - 4 = 0
x = 4
So, the correct answer is B. x = 4 and x = -10

Given tan0 = 7/24 use the Pythagorean theorem to find the value of sin 0
Answer:
Step-by-step explanation:
Don't use 0 (or any other number) to replace θ. Use a letter variable such as x.
tan(x) = 7/24
sin(x)/cos(x) = 7/24
sin(x) = 7/√(7²+24²) = 7/√625 = 7/25

25% of Mr. Foster's class chose an amber background for their school picture. If 6 students chose an amber background, how many students are in Mr. Foster's class?
Answer:
24 studentsStep-by-step explanation:
25% of a hundred is one-fourth and because there are six students in a fourth of the whole we are multiplying four and six. 6x 4 is 24.
The percentage is calculated by dividing the required value by the total
value and multiplying by 100.
Required percentage value = a
total value = b
Percentage = a/b x 100
25% = 6 students
100% = 24 students
The total number of students in Mr. Foster's class is 24.
What is a percentage?The percentage is calculated by dividing the required value by the total
value and multiplying by 100.
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Number of students who chose an amber background = 6
25% of Mr. Foster's class chose an amber background for their school picture.
This means,
25% = 6
The total number of students = 100%
Now,
25% = 6 students
Multiply 4 on both sides.
4 x 25% = 4 x 6 students
100% = 24 students
Thus,
The total number of students in Mr. Foster's class is 24.

Step-by-step explanation:
a) Work out the size of angle x. b) Give reason for your answer.
A
x=75°
B
We know that ∠EFG=∠ABF because they are corresponding angles.
We also know that ∠x+∠ABF=180, because angles along a straight line always equal 180:
x+105=180
x=75°

Answer:
13.9 mm
Step-by-step explanation:
To find the diagonal of the box, x, apply the following formula, d = √(l² + w² + h²)
Where,
d = x
l = 12 mm
w = 5 mm
h = 5 mm
Plug in the values
x = √(12² + 5² + 5²)
x = √194
x = 13.9 mm (nearest tenth)

Find the slope of the line from the table below
Answer:
m = -10
Step-by-step explanation:
m = y2 - y1 / x2 - x1
m = 60-50 / -2 - -1
m = 10/ -1
m = -10
Answer:
-10
Step-by-step explanation:
We can use two points from the table to find our slope.
Remember, the slope formula is [tex]\frac{y2-y1}{x2-x1}[/tex]. We can use the points (-1,50) and (-2,60). Let's substitute the values into the formula.
[tex]\frac{60-50}{-2-(-1)}[/tex]. This gets us to [tex]\frac{10}{-1}[/tex], so our slope is -10.
