Make x the subject of formular y=5√x+3-4
pochemuha

Answer:

x={(y+1) / 5}²

Step-by-step explanation:

y = 5√x +3 -4

⇒y = 5√x -1

add 1 on both sides

⇒ y + 1 = 5√x

divide both sides by 5

⇒(y+1) / 5   = (5√x) /5

⇒(y+1) / 5   = √x

now, square both sides

⇒{(y+1) / 5}²  = (√x)²

∴{(y+1) / 5}² = x

If you apply ghe change below to the quadratic parent function f(x)=x2 what is the equation of the new function? Shift 1 unit ri
saveliy_v [14]

1 to left gives (x -1)^2

vertical stretch makes it 5(x - 1)^2

reflection in axis changes the sign to - :-

equation of new function is f(x) = -5(x - 1)^2

An opaque cylindrical tank with an open top has a diameter of 3.25 m and is completely filled with water. When the afternoon Sun
kicyunya [14]

Answer:

10.69

Step-by-step explanation:

We must first know that the angle of refraction is given by the following equation:

n_water * sin (A_water) = n_air * sin (A_air)

where n is the refractive index, for water it is 1.33 and for air it is 1.

The angle (A) in the air is 22.8 °, and that of the water is unknown.

Replacing these values we have to:

1.33 * sin (A_water) = 1 * 0.387

sin (A_water) = 1 * 0.387 / 1.33

A_water = arc sin (0.2907) = 16.9 °

now for the tank depth:

h = D / tan (A_water)

D = 3.25

Replacing

h = 3.25 / tan 16.9 °

h = 10.69

Therefore the depth is 10.69 meters.
