Answer:
x = 4[tex]\sqrt{3}[/tex]
Step-by-step explanation:
using the cosine ratio in the right triangle and the exact value
cos30° = [tex]\frac{\sqrt{3} }{2}[/tex] , then
cos30° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{x}{8}[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex] ( cross- multiply )
2x = 8[tex]\sqrt{3}[/tex] ( divide both sides by 2 )
x = 4[tex]\sqrt{3}[/tex] ( exact value )
Step-by-step explanation:
SOHCAHTOA

Cosine●= adj/hyp
cos30= y/8
0.8660=y/8
Cross multiply
0.8660×8=y

2/3-5/6 over 3/4. What’s the answer
The value of (2/3 - 5/6) / 3/4 is -2/9.
What is a fraction?A fraction is written in the form of a numerator and a denominator where the denominator is greater that the numerator.
Example: 1/2, 1/3 is a fraction.
We have,
(2/3 - 5/6) / 3/4
2/3 - 5/6
= (4 - 5)/6
= -1/6
Now,
(-1/6 )/(3/4)
= -1/6 x 4/3
= -4/18
= -2/9
Thus,
The value is -2/9.

The table shows input and output values for three functions.
Use the drop-down menus to complete each statement.
x-intercepts exist in the function(s)
.
y-intercepts exist in the function(s)
.
The function
has the lowest minimum.
The function
has the greatest maximum.
Answer:
x-intercepts exist in the 3 functions
y-intercepts exist in the 3 functions
The function h(x) has the lowest minimum.
The function f(x) has the greatest maximum.
Step-by-step explanation:
Given
The attached table
Solving (a): x-intercepts
A function has x intercept if its y value equals 0.
From the table, we have:
[tex]f(2)=0[/tex]
[tex]g(4) = 0[/tex]
[tex]h(2) = 0[/tex]
All functions have x intercept
Solving (b): y-intercepts
A function has y intercept if its x value equals 0.
From the table, we have:
[tex]x = 0[/tex]
This applies to all functions in the table;
Hence, all functions have y intercept
Solving (c): Lowest minimum
The minimum of each function is:
[tex]f(x) = -12[/tex]
[tex]g(x) = -4[/tex]
[tex]h(x) = -60[/tex]
The lowest minimum is: h(x) because:
[tex]h(x) <f(x) < g(x)[/tex]
i.e.
[tex]-60 < -12 < -4[/tex]
Solving (d): Greatest maximum
The maximum of each function is:
[tex]f(x) = 12[/tex]
[tex]g(x) = 2[/tex]
[tex]h(x) = 0[/tex]
The greatest maximum is: f(x) because:
[tex]f(x) > g(x) > h(x)[/tex]
i.e.
[tex]12 > 2 > 0[/tex]
Answer:
1. f(x) g(x) h(x)
2. f(x) g(x) h(x)
3. h(x)
4. f(x)

Below is a diagram of a candy bar that is being shared between two people. Cut the candy bar into two pieces, A and B, so that A gets 3/5 times as much as B. What fraction of the bar does B get?
Answer:
B gets 5/13 of the candy bar.
Step-by-step explanation:
Given that a candy bar is being shared between two people, A and B, and A gets 3/5 times as much as B, to determine what fraction of the bar does B get the following calculation must be performed:
3/5 = 0.6
1.6 + 1 = 100
1 = X
2.6 = 100
1 = X
100 / 2.6 = X
38.46 = X
38.46% = 0.3846 = 5/13
Therefore, B gets 5/13 of the candy bar.

Burritos Unlimited has 3 choices of tortilla, 4 choices of meat, 2 choices of rice, 3 choices of beans, 3 choices of cheese, 4 choices of salsa, and 3 choices of extra toppings. How many different burritos can they make with 1 choice of tortilla, 1 choice of meat, 1 choice of rice, 1 choice of beans, 1 choice of cheese, 1 choice of salsa, and 1 extra topping?
Answer:
They can make 2592 different burritos.
Step-by-step explanation:
In this question:
We multiply the number of options for each condiment.
1 choice of tortilla from a set of 3.
1 choice of meat from a set of 4.
1 choice of rice from a set of 2
1 choice of beans from a set of 3
1 choice of cheese from a set of 3
1 choice of salsa from a set of 4.
1 extra topping from a set of 3.
So
3*4*2*3*3*4*3 = 2592
They can make 2592 different burritos.
The functions each model the number of students S is that played an online video game d days after each video game was released. S^1(d)= 0.45d^3-3d^2 + 4.75d +16
S^2(d)=0.09d^3-1.31d^2 +7.25d +18
Use a graphing calculator to determine the number of days after the games release that were played by the same number of students.
0.36d³ - 4.31d² - 2.5d - 2 = 0 is the function and the graph of the function is given below -
What is function?function is a mathematical phrase, rule, or law that establishes the connection between an independent variable and a dependent variable (the dependent variable).
y = x² is an illustration of this. Any input for x yields a single output for y. Because x represents the input value, one can state that y is a function of x.
To determine the number of days after the game's release that was played by the same number of students for the two functions S^1(d) and S^2(d).
Here, the functions each model the number of students S.
played an online video game d days.
We need to set the two functions equal to each other and solve for d.
S^1(d) = S^2(d)
or, 0.45d³ - 3d² + 4.75d + 16 = 0.09d³ - 1.31d² + 7.25d + 18
Subtracting 0.09d³ - 1.31d² + 7.25d + 18 from both sides we get:
or, 0.36d³ - 4.31d² - 2.5d - 2 = 0

A boat will pass the Colby bridge and the wave bridge on the dell river. Rename each other the two bridge opening times. there are 60 minutes in an hour so use 60 as a common denominator. Then rename each opening time and find another common denominator. Explain how you found your answers.
The bridge opening times when there are 60 minutes in an hour will be 45/60 and 10/60.
How to illustrate the fraction?From the information, a boat will pass the Colby drawbridge and then the Wave drawbridge and then the Wave drawbridge.
From the table, Colby is on the 3/4 hour. This will be:
= 3/4 × 60
= 45
Also, Wave Bridge will be:
= 1/6 × 60
= 10
Therefore, it's 45/60 and 10/60 because we know that the common denominator is 60 then 3/4 of an hour is 45mins then 1/6 of an hour is 10.

The 4 sides of a square are usually the same ;
Hence, each side is called the side length ; from the diagram attached :
Side length of square 4 = a + b
Side length of square 5 = a + b
If the side lengths are equal ; that is (a + b) ; the the area which is the square of the side length will also be the same.
