Answer:

Distance between Archimedes and the rock = 7.51 m ≅

Step-by-step explanation:

The sunlight makes an angle of depression of 43 degrees

Hence angle between the rock and the sunlight rays is = 90-43=47 degrees

Distance between Archimedes and the rock = Tan 47 = X/7

X = 7 tan 47 = 7.506580970172 = 7.51m ≅

If f(x) = 2x+6 find the value of h if f(h) =4
Volgvan

Answer:

18

Step-by-step explanation:

f(x) is the ultimate base of all function notation forms

f(h) is the addition of 4(Vertical Shift of 4)

f(h)=2x+10

If f(4), then 2(4)+10

f(4)=18

PLEASE HELP IF MORE THAN ONE PERSON ANSWERS ILL GIVE BRAINLIEST!!!
lina2011 [118]

Answer:

see explanation

Step-by-step explanation:

The area of the shaded portion is the area of the outer circle subtract the area of the inner circle

area of larger circle = πr² ← r is the radius = 11

area = π × 11² = 121π

area of smaller circle = πr² ← r = 9

area = π × 9² = 81π

-----------------------------------------

shaded area = 121π - 81π = 40π m² ≈ 126 m²

The height of a cable that runs between two supports on a suspension bridge can be modeled by a quadratic function () where is t
Murrr4er [49]

What is the vertex

Its vertex is at (36, -10)

Let us assume that the left edge of the cable is at the origin.

Since the cable is at its lowest height 10 feet halfway between the two supports, the y-coordinate of its lowest point is -10 ft and the x coordinate is 72 ft/2 = 36 ft.

So, its vertex is at (36, -10)

Axis of symmetry

The y-axis.

Since the cable is symmetric about its lowest point, the axis of symmetry is the y-axis.

Domain

The domain is (0, 72).

Since the minimum value of its x-coordinate is at the origin which is x = 0 and the maximum value is at the other support which is at x = 72 ft,

the domain is (0, 72).

Range

The range is (0, -10)

Since the minimum value of the y-coordinate is -10ft and the maximum value is at the origin y = 0,

the range is (0, -10)

x and y-intercepts

The x-intercept is (0, 72) and the y-intercept is (0, 0)

Since the cable is attached at the origin and at 72 feet away  from the origin at the other support, the x-intercept is 0 and 72 ft and the y-intercepts are 0 and 0.

So, the x-intercept is (0, 72) and the y-intercept is (0, 0)
