Write the formula of the function, where x is entered in radians.
f(x)= ?
Answer:
f(x)=-5sin (1/3x)-2
Step-by-step explanation:
The formula of the function, where x is entered in radians is f(x) = [tex]5sin(\frac{\pi x}{2})-2[/tex]
What is Sinusoidal function?A sine wave, sinusoidal wave, or just sinusoid is a mathematical curve defined in terms of the sine trigonometric function
Given,
Midline is at (0,-2)
minimum point at [tex](\frac{3\pi }{2},-7)[/tex]
Therefore, the function is line with amplitude = -2-(-7)=5
No phase shift as intersection at 0.
Vertical shift is -2
Then,
f(x) = [tex]5sin(\frac{\pi x}{2})-2[/tex]
Hence, The formula of the function, where x is entered in radians is f(x) = [tex]5sin(\frac{\pi x}{2})-2[/tex]

Joe has $173 in the bank. He earns the same amount of money each week for 7 weeks and puts this money in the bank. Now joe has $208 in the bank. How much money does joe earn each week
Given:
Joe has $173 in the bank.
He puts 7 weeks earning in the banks.
Now joe has $208 in the bank.
To find:
How much money does joe earn each week?
Solution:
Let x be the same amount of money each week for 7 weeks and puts this money in the bank.
Total earning in 7 weeks = 7x
Total amount of money in bank = Initial amount + 7 Weeks earning
[tex]208=173+7x[/tex]
[tex]208-173=7x[/tex]
[tex]35=7x[/tex]
Divide both sides by 7.
[tex]\dfrac{35}{7}=x[/tex]
[tex]5=x[/tex]
Therefore, joe earns $4 each week.
What are the points on y-axis which are at a distance of 4 units from 4x+3y=12
Given:
The equation of line is
[tex]4x+3y=12[/tex]
To find:
The points on y-axis which are at a distance of 4 units from the given line.
Solution:
The point lie on the y-axis. So, their x-coordinate must be zero.
Let the points are in the form of (0,k).
The distance between a point [tex](x_0,y_0)[/tex] and a line [tex]ax+by+c=0[/tex] is
[tex]d=\dfrac{|ax_0+by_0+c|}{\sqrt{a^2+b^2}}[/tex]
The given equation can be written as
[tex]4x+3y-12=0[/tex]
The distance between (0,k) and [tex]4x+3y-12=0[/tex] is 4 units.
[tex]4=\dfrac{|4(0)+3(k)-12|}{\sqrt{4^2+3^2}}[/tex]
[tex]4=\dfrac{|0+3k-12|}{\sqrt{16+9}}[/tex]
[tex]4=\dfrac{|3k-12|}{\sqrt{25}}[/tex]
[tex]4=\dfrac{|3k-12|}{5}[/tex]
Multiply both sides by 5.
[tex]20=|3k-12|[/tex]
[tex]\pm 20=3k-12[/tex]
[tex]12\pm 20=3k[/tex]
[tex]\dfrac{12\pm 20}{3}=k[/tex]
Now,
[tex]k=\dfrac{12-20}{3}\text{ and }k=\dfrac{12+20}{3}[/tex]
[tex]k=\dfrac{-8}{3}\text{ and }k=\dfrac{32}{3}[/tex]
Therefore, the two points are [tex]\left(0,\dfrac{-8}{3}\right)\text{ and }\left(0,\dfrac{32}{3}\right)[/tex].

The ratio of two sides of a parallelogram is 3:4 and the perimeter is 28 in. Find the lengths of the sides of the parallelogram.
Answer:
the lengths of sides are 8 and 6.
Step-by-step explanation:
Let us denote side lengths of the parallelogram as x and y.
Then first condition can be written as x/y=3/4.
Second condition can be written as 2x+2y=28.
We can multiply both sides of the first equation by y and get x=(3y)/4.
Now we have x expressed in terms of y. It is convenient because we can substitute x in the second equation:
2(3y/4)+2y=28
And we can solve it for y.
1.5y+2y=28
3.5y=28
y=8
What is left is to find x. We may use the expression for x again: x=(3*8)/4=6
Ans: the lengths of sides are 8 and 6.

WRITE AN EQUATION which describes the line that contains (9,4) and has an undefined slope.
Answer:
x = 9
Step-by-step explanation:
A line with an undefined slope will be a vertical line.
This means the equation of the line will be in x = form, because the line will only go through one x value.
Since the given point has the x value of 9, this means the line will only go through that value.
So, the equation of the line will be x = 9

Maria Contrerras earned $53,000 in taxable income. She figured her tax from the single taxpayer table above.
1. Find her earned income level.
2. Entered the base amount. = $
3. Found the amount over $ = $
4. Multiplied line 3 by 25% = $
5. Added Lines 2 and 4 = $
Tax= $ 7,173.5
Step-by-step explanation:
Her taxable income is $ 43,000 which lies in the tax category $ 31,850 to
$ 77,100.
Tax for $ 31,850 is $ 4,386
Plus 25% of the amount = ( $ 43,000- $ 31,850 )= $ 11,150 over
25 % of $ 11,150= $ 2,787.5
Total Tax= $ 4386 + $ 2787.5= $ 7,173.5
It costs Johnny $15 a month plus $1.50 per song to download music. This situation is represented by the expression 1.5x + 15, where x is the number of songs downloaded. How much will it cost Johnny to download 10 songs?
please hurry I need to pass math
Answer:
$30
Step-by-step explanation:
To find the cost, plug in 10 for x, then simplify
1.5x + 15
1.5(10) + 15
= 30
So, it will cost Johnny $30 to download 10 songs
The total amount of money that Johnny will have to pay is f(10) = 30.
What are expressions?A mathematical expression is made up of terms (constants and variables) separated by mathematical operators
Given is that it costs Johnny $15 a month plus $1.50 per song to download music. This situation is represented by the expression →
1.5(x) + 15.
The expression is given by -
f(x) = 1.5(x) + 15
where [x] is the number of songs downloaded.
For [x] = 10 songs, the total amount of money that Johnny will have to pay is -
f(10) = 1.5 x 10 + 15
f(10) = 15 + 15
f(10) = 30
Therefore, the total amount of money that Johnny will have to pay is f(10) = 30.

A new phone costs $230 and the sales tax rate is 7%. What is the total cost of the camera after tax?
That's a question about percentage.
One way to represent percentage is using decimal number. In this way, 1 is equivalent to 100% and the other less percentages using numbers between 0 and 1.
Examples:
90% is equivalent to 0,90.5% is equivalent to 0.05. It's not 0.5 because 0.5 is equivalent to 50%.13.17% is equivalent to 0.1317.245% is equivalent to 2.45.If we want to know the percentage of a number, we should multiplacate the number by the porcentage in the decimal number form.
Examples:
55.90% of 200 is equal to: [tex]200 \times 0.5590 = 111.8[/tex]360% of 88 is equal to: [tex]88\times 3.6 = 316.8[/tex]In our problem, we have a phone with a increase of 7%. To solve that, it's important to perceive that $230 is equal to 100% and with a increase of 7%, we will pay 107%.
107% in the decimal number form is 1.07. With that information, we should multiplicate 1.07 by the original value and we will find the answer.
We know that [tex]230\times 1.07 = 246.1[/tex], therefore, the total cost of the phone after tax is $246.1.

Question 3
For the triangle shown, calculate the perimeter
2.5 km
51.8°
62.1
Answer: The perimeter is 9.31km
Step-by-step explanation:
We have two triangle rectangles, and the perimeter of the complete triangle will be equal to the sum between the hypotenuses (of both triangles) and the bottom cathetus (of both triangles)
For a triangle rectangle and a given angle A (that is not the right angle)
Remember the relationships:
Sin(A) = (opposite cathetus)/(hypotenuse)
Cos(A) = (adjacent cathetus)/(hypotenuse)
Tan(A) = (opposite cathetus)/(adjacent cathetus)
With this, we can find the measures of each triangle in the imae.
The left triangle rectangle.
We have a cathetus (opposite) with length of 2.5km and A = 51.8°
Then the hypotenuse can be found by:
Sin(51.8°) = (2.5km)/(hypotenuse)
then:
hypotenuse = (2.5km)/sin(51.8°) = 3.18 km
And the bottom cathetus can be found with:
Tan(51.8°) = (2.5km)/(adjacent cathetus)
adjacent cathetus = (2.5km)/(Tan(51.8°)) = 1.98 km
For the other triangle, we have A = 62.1°, and the opposite cathetus is 2.5 km
We can use the same relationships than before:
Sin(62.1°) = (2.5km)/(hypotenuse)
then:
hypotenuse = (2.5km)/sin(62.1°) = 2.83 km
And the bottom cathetus can be found with:
Tan(62.1°) = (2.5km)/(adjacent cathetus)
adjacent cathetus = (2.5km)/(Tan(62.1°)) = 1.32 km
Then the perimeter of the complete triangle is:
Perimeter = 3.18 km + 1.98 km + 2.83km + 1.32 km = 9.31 km

Four individuals put their money together to start a new venture. They agree to split the profits equally. N invests $1,000, X invests $2,000, Y invests $3,000 and Z invests $4,000. If the profits for the first month were $2,000, Z receives __?__ less than if the profits were divided in proportion to how much they invested.
Answer: $800
Step-by-step explanation:
N invests $1,000, X invests $2,000, Y invests $3,000 and Z invests $4,000. This in the ratio of 1:2:3:4.
If the profits for the first month were $2,000, the amount received by Z will be:
= 4/(1+2+3+4) × $2000
= 4/10 × $2000
= 4 × $200
= $800

Rewrite the equation so that it does not have fractions 2- 5/6x = 7/8
the common denominator of 5/6 and 7/8 is 24, so multiply both sides of the equation (every term) by 24:
24(5/6)x + 24(2) = 24(7/8)
the denominators will cancel out so you have:
4(5x) + 48 = 3(7)
do the multiplication:
20x + 48 = 21
fractions have been eliminated, and if you want to continue to solve:
20x = -27
x = -27/20
