Answer:

15-2x.

Step-by-step explanation:

Let the number be x that needs to be subtracted.

The twice of a number = 2x.

15 is decreased by twice a number

Hence, subtract 2x from 15 i.e, 15-2x

As given according to the question,

The equation will be written as

15-2x

Thus, the answer is 15-2x.

How to prove points belong to the same circle
kenny6666 [7]
Not sure what the mess above me says, but basically as long as you have an equation for the circle, you can plug the coordinates of your point into the x and y values of the equation and see if it equals out. If you don’t have an equation, you can just make one. Use (f-k)^2+(x-h)^2=r^2 where h and k are the coordinates of the center of the circle and r is the radius. Hope this helps!

Step-by-step explanation:

Complete Question

What is the average velocity of the rock in first 2 secs?

Solution

Distance travelled in first two seconds  

4.9 t^2 = 4.9*2*2 = 19.6 m

Average speed = S2-S1/2 = 19.6-0/2 = 9.8 meter per second

Helia invested 4000 AED for 3 years with a compound interest rate of 1.5%, Calculate the worth of her investment at the end of t
sineoko [7]

Answer:

4180 AED

Step-by-step explanation:

Given data

Principal= 4000

Time= 3 years

Rate= 1.5%

The compound interest expression is given as

A= P(1+r)^t

substitute

A=4000(1+0.015)^3

A= 4000(1.015)^3

A= 4000*1.045

A= 4180

Hence the worth will be  4180 AED

According to the fundamental theorem of algebra, how many zeros does the function f(x) = 4x3 − x2 − 2x + 1 have?
jarptica [38.1K]

Answer: 3 zeroes.


Explanation:-

  • The fundamental theorem of algebra states that any polynomial with degree m>0  and complex coefficients has atleast one complex root.
  • Corollary of fundamental theorem states that for any polynomial with degree m>0 has exactly m solutions.

The given function is f(x)=4x^3-x^2-2x+1

Because it is a polynomial function with degree 3>0 , Therefore by corollary of fundamental theorem of algebra , it has 3 zeroes.
