give the exact form and decimal form of the equation
8=9sin(6x)
simplify the equation into the form sin(ax)=b and use the inverse sin to solve for x
Answer:
Exact form: [tex]\sin{(6x)} = \frac{8}{9}[/tex]
Decimal form: [tex]\sin{(6x)} = 0.8889[/tex]
The solution for x is: The solution for x is of 10.455º
Step-by-step explanation:
We are given the following equation:
[tex]8 = 9\sin{(6x)}[/tex]
Placing into the desired format, the exact format is:
[tex]\sin{(6x)} = \frac{8}{9}[/tex]
In the decimal part, we divide 8 by 9. So
[tex]\sin{(6x)} = 0.8889[/tex]
Solving for x:
We apply the inverse sine. So
[tex]\sin^{-1}{\sin{(6x)}} = \sin^{-1}{0.8889}[/tex]
[tex]6x = 62.73[/tex]
[tex]x = \frac{62.73}{6}[/tex]
[tex]x = 10.455[/tex]
The solution for x is of 10.455º

1. A piece of steel has a volume of 12 cm3
and a mass of 96g. What is its density?
Answer:
it's density is 8 g /cm³
Step-by-step explanation:
Mass (m) = 96 g
Volume (v) = 12 cm³
Density (d) =?
We know density is defined as mass per unit volume so
d = m/v
= 96 / 12
= 8 g/cm³
Hope it will help :)
Note : if in the question it is said to write in sI system u have to write in kg/m³.
32 students make up 100% of the class, what would the percentage be for 3 students
Answer:
Step-by-step explanation:
32=100%
3=3/32 x 100%
=300/32%
=9 3/8%
The percentage to be for 3 students if 32 students make up 100% of the class is 9.375%.
What is percentage?A percentage, often known as percent, is a division by 100. Percentage, which means "per 100," designates a portion of a total sum.
Given:
32 students make up 100% of the class
Calculate the percentage of one student,
1 student = 100 / 32 = 3.125 %
Calculate the percentage of 3 students
3 students = 3.125 × 3 = 9.375%
Therefore, the percentage to be for 3 students if 32 students make up 100% of the class is 9.375%.

The Montgomery Company tells Squeaky Clean that most of their buildings are 40 feet tall. Squeaky Clean decides to use ladders to reach the upper windows. The base of the ladder works best on the sidewalk so it needs to be 9 feet away from the building. How tall should the ladder be in order to reach the top of the building?
Answer: 41 feet
Step-by-step explanation: The ladder, the building and the sidewalk creates a right triangle, with the 90° formed at the junction of sidewalk and building, so the length of the ladder is the triangle's hypotenuse.
To determine hypotenuse, use Pythagorean's theorem:
[tex]h^{2}=s^{2}_{1}+s^{2}_{2}[/tex]
[tex]h=\sqrt{40^{2}+9^{2}}[/tex]
[tex]h=\sqrt{1681}[/tex]
h = 41
For the ladder to reach the top of the building, it has to be 41 feet tall.
A deli sells 2 hot dogs for $2.50. What is the constant of proportionality of dollars per hot dog?
Answer:
$1.25 per hot dog
Step-by-step explanation:
Since we have given that
A deli sells 2 hot dogs for $2.50
i.e.
Cost of 2 hot dogs = $2.50
And we need to find the constant of proportionality of dollars per hot dog, for which we'll use unitary method.
So,
Cost of 1 hot dog is given by
2.50/2=$1.25
So, Cost of per hot dog is $1.25.

Complete the following sentence
If x is to 6 as 10 is to 15, then x is equal to .
Answer:
x=4
Step-by-step explanation:
x/6 = 10/15
x/6 = 2/3
3x=12
Answer:
x=4
Step-by-step explanation:
To find this, you must first figure out the relationship between 10 and 15. Since 10 is 2/3 of 15, "x" must be 2/3 of 6.
To find "x", divide 6 by 3 to get 2, then 2 by 2 to get 2/3 of 6 (4). Thus meaning X = 4.

Which of these function has a greater rate of change than the function graphed bean why
1
3
12
.
12
Oya 2x + 12, because the rate of change of the graphed function is 9
y = 10x + 1, because the rate of change of the graphed function is 3
Oy10x 1, because the rate of change of the graphed function is 9
y = 212, because the rate of change of the graphed function in 3
Answer:
The 2nd option is correct.
i.e.
y = 10+1, because the rate of change of the graphed function is 3.
Step-by-step explanation:
From the graph,
Taking two points
(0, 0)(3, 9)Finding the rate of change or slope between (0, 0) and (3, 9)
Using the formula
Rate of change = Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [9 - 0] / [3 - 0]
= 9 / 1
= 3
Thus, the rate of change or slope of the line = m = 3
The slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where
m is the rate of change or slopeb is the y-interceptConsidering the function in 2nd option
y = 10x+1
Comparing with the slope-intercept form of the line equation y = mx+b
The rate of change or slope = m = 10
Conclusion:
The rate of change or slope of the graphed line: m = 3
The rate of change or slope of y = 10x+1 is: m = 10
Thus, the rate of change of y = 10x+1 i.e. m = 10 is greater than the rate of change of the graphed line i.e. m = 3.
Hence, the 2nd option is correct.
i.e.
y = 10+1, because the rate of change of the graphed function is 3.

Roxanne likes to fish. She estimates that 30% of the fish she catches are trout, 20% are bass, and 10% are perch. She designs a simulation.
Let 0, 1, and 2 represent trout.
Let 3 and 4 represent bass,
Let 5 represent perch.
Let 6, 7, 8, and 9 represent other fish.
The table shows the results:
The probability helps us to know the chances of an event occurring. The probability of Roxanne catching bass is 60%.
What is Probability?The probability helps us to know the chances of an event occurring.
[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]
For the next four of the fishes to be bass, the numbers in the table must contain the digit 3 or 4 in it. Therefore, the cases where Roxanne catches bass are:
263520534526699443483087832335793840683933637683Also, it is mentioned that the total number of cases is 20 (Given in the table). Therefore, the probability of catching a bass can be written as,
[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}\\\\\\Probability=\dfrac{\text{Number of cases where Roxanne catches fish}}{\text{Total number of catches}}\\\\\\Probability = \dfrac{12}{20} = 0.60\\\\Probability = 60\%[/tex]
Hence, the probability of Roxanne catching bass is 60%.

<AOP + < BOP = 180°< being linear pair >
x + 30° + x - 30° = 180°
2x = 180°
x = 90°
Now
<AOP = x + 30° = 90° + 30° = 120°
<BOP = x - 30° = 90° - 30° = 60°
<AOP is obtuse angle because it is less than 180° but more than 90°.<BOP is acute angle because it is less than 90°.Hope it will help :)❤

Evaluate the expression 53 ÷ (13 − 8) × 2.
Answer:
im confused too so lets work together!
Step-by-step explanation:
(13 - 8 = 5.) so, rewrite the problem as 5 cubed divided by (5) x 2! Now, we figure out 5 cubed. 5 x 5 equals 25, x 5 equals 125. So, 125 divided by 5 would be 25. Now, 25 x 2 is 50.
