Answer:

Choice c is correct.

Step-by-step explanation:

We have  given two functions:

f(x)  = (2x²+ 2)

g(x) = (x²-1)

We have to find (f-g)(x).

(f-g)(x) = ( 2x²+ 2) - ( x²-1)

(f-g)(x) = 2x² + 2 - x²+1

(f-g)(x) = x²+3 is the correct answer.

Answer: OPTION C

Step-by-step explanation:

To solve the exercise shown in the image attached, you need to subtract the functions f(x) and g(x).

Keeping the above on mind, you have:

(f-g)(x)=2x^{2}+2-(x^{2}-1)

You must distribute the negative sign and then you must add the like terms, therefore, you obtain:

(f-g)(x)=2x^{2}+2-x^{2}+1\\(f-g)(x)=x^{2} +3

Daniel has $30 in a savings account that earns 5%
kaheart [24]

If Daniel has $30 in a savings account that earns 5% annually and the interest is not compounded,then he will get $33 after 2 years.

Given that Daniel has $30 in a savings account that earns 5% annually and the interest is not compounded.

We are required to find the amount of money that Daniel will get after 2 years.

Since the amount is not compounded so interest will be same in all years as if in the first year.

The interest will be 2*30*0.05=3

The total amount including interest=30+3

=$33

Hence if Daniel has $30 in a savings account that earns 5% annually and the interest is not compounded,then he will get $33 after 2 years.

What additional information is needed to prove triangle LMN is congruent to triangle KMN using the HL theorem?
IgorC [24]
<h2>Answer:</h2>

∠LMN is a right angle

<h2>Step-by-step explanation:</h2>

If we want to prove that two right triangles are congruent by knowing that the corresponding hypotenuses and one leg are congruent, we begin as follows:

  • Since two legs are congruent and we know this by the hash marks, then the triangle ΔLKN is isosceles.
  • By definition LN ≅ NK
  • If ∠LMN is a right angle, then MN is the altitude of triangle ΔLKN
  • Also MN is the bisector of LK, so KM ≅ ML
  • So we have two right triangles ΔLMN and ΔKM having the same lengths of corresponding sides
  • In conclusion, ΔLMN ≅ ΔKMN

Let f(x) =[[x]], what is f(-5.2)​
ANEK [815]

flooring a value, simply means, dropping it to the closest integer, so for the floor function or ⌊x⌋, that means

⌊ 2.5 ⌋ = 2

⌊ 2.00000001 ⌋ = 2

⌊ 2.999999999999⌋ = 2

⌊ -2.0000000001⌋ = -3

⌊ -2.999999999999⌋ = -3

let's recall that on the negative side of the number line, the farther from 0, the smaller, so -1,000,000 is a tiny number compared to the much larger -1.

⌊ -5.2 ⌋ = -6.
