Find The Volume Of The Right Cone Shown As A Decimal Rounded To The Nearest Tenth.980.2 M^22205.4 M^23308.1

Answers

Answer 1

Answer:

B

Step-by-step explanation:

Radius = diameter / 2 = 18/2 = 9 m

Volume = (radius^2 x pi x height)/3  = (9^2 x pi x 26)/3  = 2205.4 m^3

Answer 2

Answer:

[tex]\huge\boxed{V=2204.3m^3}[/tex]

Step-by-step explanation:

The formula of a volume of a cone:

[tex]V=\dfrac{1}{3}\pi r^2H\\\\r-\text{radius}\\H-\text{height}[/tex]

We have:

[tex]2r=18m\to r=\dfrac{18m}{2}=9m\\\\H=26m[/tex]

substitute:

[tex]V=\dfrac{1}{3}\pi(9^2)(26)=\dfrac{1}{3}(81)(26)\pi=(27)(26)\pi=702\pi(m^3)[/tex]

use π ≈ 3.14

[tex]V\approx(702)(3.14)=2204.28(m^3)\approx2204.3[/tex]

The ramp on the back of a moving van is 7 ft high and rises at an angle of 28°. How long is the ramp? Round to the nearest foot.

Answers

Answer:

6 feets

Step-by-step explanation:

Height of ramp = 7feets

θ = 28°

Length of ramp = x

Using trigonometric relation :

Sin θ = opposite / hypotenus

Sin 28 = 3 / x

0.4694715 = 3 / x

0.4694715x = 3

x = 3 / 0.4694715

x = 6.39 feets

The length of the ramp = 6 feets

find the inverse of f(x)= 2x/(5x+6)​

Answers

Answer:

[tex]f(x) = \frac{2x}{5y+6}[/tex]

Step-by-step explanation:

Answer:

Below!

Step-by-step explanation:

f(x) = 2x/5x+6

Sub y for f(x) : y = 2x/5x+6

Swap x and y : x = 2y/5y+6

Multiply both sides by 5y+6 : 2y = (5y + 6) x

Distribute x : 2y = 5xy + 6x

Change sign : 2y - 5xy = 6x

Factor out y : (2-5x)y = 6x

Divide both sides by 2-5x : y = 6x/2-5x

Substitute for y : f^-1(x) = 6x/2-5x

Answer: f^-1(x) = 6x/2-5x

The sum of the arithmetic series is:

893

What are arithmetic progressions?

An arithmetic sequence with a specific number of terms is the sum of all the terms in an arithmetic series.

An arithmetic sequence's first n terms are added together to form (n/2).(a1+an). The arithmetic series formula is what it is known as.

Solution:

Given:

a1 = 11, a2 = 15 and an=83

Step-1:

d= a2 ₋ a1

d= 4

Now, an = a ₊ (n ₋ 1)d

          83 = a ₊ (n ₋ 1)4

          83 = 11 ₊ 4n ₋4

          83 = 7 ₊ 4n

         4n = 83 ₋ 7

          n = 19

Step-2:

Now, Sn = n/2 (a1 ₊ an)

         Sn = 19/2 (11 ₊ 83)

         Sn = 19/2 ₓ 94

         Sn = 893

Hence we get the answer as 893

Answers

Answer:

her salary after 8 years is $26,602

Step-by-step explanation:

Given that

Fiona salary is $21,000

She received 3% raise each year

We need to find her salary after 8 years

So, here we apply the future value formula

i.e.

= Present value × (1 + rate of interest)^number of years

= $21,000 × (1 + 0.03)^8

= $21,000 × 1.03^8

= $26,602

hence,  her salary after 8 years is $26,602
