Consider this linear function y=1/2x+1 plot all ordered pairs for the values in the domain D:{-8,-4,0,2,6}
devlian [24]

Answer:

Following are the calculated points to the given question:

Step-by-step explanation:

When\ x=-8\\\\y=\frac{1}{2}(-8)+1=-3\\\\

so,  

Point \ A(-8,-3)

When\ x=-4\\\\y=\frac{1}{2}(-4)+1=-1\\\\

so,  

Point \ B(-4,-1)

When\ x=0\\\\y=\frac{1}{2}(0)+1=1\\\\

so,  

Point \ C(0,1)

When\ x=2\\\\y=\frac{1}{2}(2)+1=2\\\\

so,  

Point \ D(2,2)

When\ x=6\\\\y=\frac{1}{2}(6)+1=4\\\\

so,

Point \ E(6,4)

Approximate the area between the xxx-axis and h(x) = \dfrac{1}{7-x}h(x)= 7−x 1 ​ h, (, x, ), equals, start fraction, 1, divided
tiny-mole [99]

Answer:

\dfrac{47}{60} sq. units.

Step-by-step explanation:

The given function is

h(x)=\dfrac{1}{7-x}

We need to find the area between x-axis and the given function from x=2 to x=5.

Left Riemann sum formula of area:

Area=\sum_{n=0}^{N-1}f(x_n)(\Delta x_n)

For given question,

Area=\sum_{n=2}^{5-1}f(x_n)(\Delta x_n)

Area=\sum_{n=2}^{4}f(x_n)(\Delta x_n)

Area=f(x_2)(3-2)+f(x_3)(4-3)+f(x_4)(5-4)

Now,

Area=\dfrac{1}{7-2}\times (1)+\dfrac{1}{7-3}\times (1)+\dfrac{1}{7-4}\times (1)

Area=\dfrac{1}{5}+\dfrac{1}{4}+\dfrac{1}{3}

Area=\dfrac{12+15+20}{60}

Area=\dfrac{47}{60}

Therefore, the required area is \dfrac{47}{60} sq. units.

The volume of this cone is 3,183.96 cubic meters. What is the height of this cone?
Rom4ik [11]

Answer:

height = 18m

Step-by-step explanation:

cone volume = 3183.96 m³

1/3 πr²h = 3183.96

1/3×3.14×13×13×h = 3183.96

h = 3183.96×3/13×13×3.14

h = 9551.88/530.66

h = 18
