Answer:
let the width be x
so 3x × x = 48
=> 3x^2 = 48
=> x^2 = 16
=> x = 4
So the length = 4×3 = 12 inches
breadth= 4 inches

What Is Sin of Sin Inverse of x?The inverse sine function (also called arcsine) is the inverse of sine function. Since sine of an angle (sine function) is equal to ratio of opposite side and hypotenuse, thus sine inverse of same ratio will give the measure of the angle.
sin ([tex]sin^{-1}x[/tex]) = x, whenever x ∈ [-1, 1] and
sin ([tex]sin^{-1}x[/tex]) is NOT defined whenever x ∉ [-1, 1].
Given
[tex]sin^{-1} (sin17^{0} )[/tex]
Cancel out [tex]sin^{-1}[/tex] and sin
[tex]sin^{-1} (sin17^{0} )[/tex] = [tex]17^{0}[/tex]

Select the correct answer from each drop-down menu. Javier purchased a digital camera for $384. The value of the camera depreciates by 25% every year. This situation represents . The rate of growth or decay, r, is equal to . So the value of the camera each year is times the value in the previous year. It will take years for the value of the camera to reach $162.
Answer:
it will take 3 yrs for the value of camera to reach $162.
Step-by-step explanation:
Pd = P(1-R/100)^T
162 = 384(1-25/100)^T
162/384 = (3/4)^T
27/64 = (3/4)^T
(3/4)^3 = (3/4)^T
T = 3
Answer:
this represents: exopnential decay, the rate of growth or decay is equal to: 0.25, value of the camera each year is: 0.75, it will take 3 years.

Answer:
121/4
Step-by-step explanation:
To complete the square, we have to work with the coefficient of x
We have to divide the coefficient of x by 2, square it and add it to both sides
So we divide 11 by 2; which is 11/2; then square it
we have this as 121/4
This number is what we are going to have added

You haft too use elimination to solve this thank you
Answer:
x=0, y=-2
Step-by-step explanation:
Because 9y appears twice in both equations, you can subtract the equations to eliminate the y variable so you can solve for x:
-7x + 9y = -18
-(4x + 9y = -18)
__________
-11x = 0
x = 0
Since we know x=0, then we plug it back into one of the equations to get the value of y:
-7x + 9y = -18
-7(0) + 9y = -18
0 + 9y = -18
9y = -18
y = -2
Therefore, x=0, and y=-2

A worker earns a 3% increase in her annual salary for each of 5 years. They plan to continue working in their position for an additional n years. If they continue to earn a 3% increase in their annual salary, what statement could describes the expression that can be used to calculate the total percent increase in their annual salary from the first year to the last year
Answer:
Given that a worker earns a 3% increase in her annual salary for each of 5 years, and they plan to continue working in their position for an additional N years, if they continue to earn a 3% increase in their annual salary, to determine what statement could describe the expression that can be used to calculate the total percent increase in their annual salary from the first year to the last year the following calculation should be performed:
1 + 0.03 (interest rate) ^ N (number of years) = final interest rate
1.03 ^ N = Final interest rate
Thus, for example, if it were invested for 5 years, the equation would operate as follows:
1.03 ^ 5 = X
1.16 = X
The total percent increase in their annual salary from the first year to the last year is [tex](1.03)^n[/tex].
What is Percentage?A percentage is a way to describe a part of a whole. such as the fraction 1/4 can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
As it is given that the annual salary of the worker increases at a rate of 3%. therefore, the salary of the worker increases compounded at a rate of 3% annually. Therefore, the salary of the worker after n number of years can be written as,
[tex]A = P(1+\dfrac{r}{100})^n[/tex]
where A is the final salary of the worker, P is the initial salary of the worker, r is the rate at which the salary is increasing, and n is the number of years.
Substituting the values in the formula,
[tex]A = P(1+\dfrac{3}{100})^n\\\\A = P(1.03)^n[/tex]
Hence, the total percent increase in their annual salary from the first year to the last year is [tex](1.03)^n[/tex].

-112/3 x (-4 1/5) =?
Answer:
sorry Wala po akong answer ehhh sorry
Can someone do this please
Answer:
124 degrees
Step-by-step explanation:
We know that a straight line is equal to 180 degrees. Therefore, all of these angles combined have to be equal to 180 degrees. This means the equation will be 3x+94+x+30+2x-4=180. Combine like terms to get 6x+120=180. 6x=60. x=10. Now that we know x, we plug it into the equation to find angle AOC. This will make the equation 3(10)+94. This is equal to 30+94 which is equal to 124. Therefore, angle AOC is equal to 124 degrees.

Can you make y=-(x+2)^2+17 standard form?
Answer:
y = - x² - 4x + 13
Step-by-step explanation:
The equation of a parabola in standard form is
y = ax² + bx + c ( a ≠ 0 )
Given
y = - (x + 2)² + 17 ← expand factor using FOIL
= - (x² + 4x + 4) + 17 ← distribute parenthesis by - 1
= - x² - 4x - 4 + 17 ← collect like terms
y = - x² - 4x + 13
Answer:
y = -x² -4x +13
Step-by-step explanation:
y = - ( x+2)² + 17
y = - x² -4x -4 +17
y = -x² -4x +13
