A.Find the L.C.M of 18, 40, and 75.<br>​
Slav-nsk [51]

Answer:

1800

Step-by-step explanation:

→ First of all we need to find the prime factorisation of the numbers.

18 = 2 × 3 × 3 or 2 × 3²

40 = 2 × 2 × 2 × 5 or 2³ × 5

75 = 3 × 5 × 5 or 5² × 3

→ Now find the number that appear twice or more and write them down

3 and 3 from 18

2, 2 and 2 from 40

5 and 5 from 75

→ Now multiply all of these numbers together

3 × 3 × 2 × 2 × 2 × 5 × 5 = 3² × 2³ × 5² = 1800

Find the volume V of the cone. Round your answer to the nearest tenth.
uranmaximum [27]
The volume of cone formula is 1/3 times pi times radius^2 times height. So in this case the formula which numbers substituted in would be 1/3 times pi times 8^2 times 12. The final answer would be 804.2477 and if rounded it would be 804.2 m^2

What is the equation of the exponential function??
Alex787 [66]

Answer:

  • $19500

Step-by-step explanation:

<u>Let the depreciation rate is x per year, then we have:</u>

  • 28000*x² = 22000
  • x² = 22000/28000
  • x² = 0.7857
  • x = √0.7857
  • x = 0.8864

<u>Exponential function for this case is:</u>

  • V(t) = 28000*0.8864^t, where V(t) - future value, t- number of years

<u>Value of the car after 3 years:</u>

  • V(3) = 28000*0.8864^3
  • V(3) = 19500

How to Factor 3x^2-x-10
adoni [48]

Solution

( − 2)(3 + 5)

Step-by-step solution:

Use the sum-product pattern

3x^2−−10

3^2+5−6x−10

Common factor from the two pairs

3^2+5−6−10

(3+5)−2(3+5)

Rewrite in factored form

(3+5)−2(3+5)

(−2)(3+5

hope this was good! <3
