Answer:

C) 2094.40

nearest answer.

Step-by-step explanation:

Since the given region is bounded by y = x, y = 10 and x = 0

⇒ 0 ≤ y ≤ 10

Radius and Height are 'y'

∴ The required volume

= ∫₀¹⁰2π(radius)(height)dy

= ∫₀¹⁰2π (y) (y) dy

= ∫₀¹⁰2π y² dy

= 2π ∫₀¹⁰ y² dy

Integrate y

= 2\pi [\frac{y^3}{3}]_0^{10}

= 2\pi [\frac{10^3}{3} - 0]

= \frac{2000}{3} \pi

where π is 3.142

= 2,094.66

Find an equation of variation where y varies directly as x and y = 7 when x = 0.5 .
Alisiya [41]

Answer:

y = 14x

Step-by-step explanation:

Use the direct variation equation, y = kx

Plug in 7 as y and 0.5 as x, and solve for k:

y = kx

7 = k(0.5)

14 = k

Plug this into the equation:

y = kx

y = 14x

So, the equation of variation is y = 14x

Graphing Exponential Functions In Exercise, sketch the graph of the function.
denis23 [38]

Answer:

The graph of the function f(x) = (1/2)^2x + 4 is attached as image below.

Analysis:

We have two intersection points in the graph

The function f(x) = (1/2)^2x + 4  intersects the y-axis at points (0,4)

The function f(x) = (1/2)^2x + 4  intersects the x-axis at points (-16,0)

f(x) is positive for x>-`16

f(x) is negative for x<-`16

Please I need help
Dimas [21]

Answer:

Step-by-step explanation:

The directrix is a vertical line, so the parabola is horizontal. The focus lies to the left of the directrix, so the parabola opens to the left.

For a left-opening parabola:

x = a(y-k)²+h,

a < 0,

vertex (h,k)

focal length p = 1/|4a|

focus (h-p, k)

directrix: x=h+p

Apply your data

focus (1,-4)

directrix x=2

vertex (1.5,-4).

focal length p = 0.5

a = -1/|4p| = -½

x = -½(y-2)²+ ½
