Line CD passes through points (0, 2) and (4, 6). Which equation represents line CD?

Mathematics

Answer:

A line in form of y = ax + b passes (0, 2)

=> 2 = 0x + b => b = 2

This line also passes (4, 6)

=> 6 = 4x + 2 => x = 1

=> Equation of this line: y = x + 2

=> Option C is correct

Hope this helps!

HELP!!! 20 POINTS!!! URGENT!!!

We know that :

$\clubsuit$ $ln(A) - ln(B) = ln(\frac{A}{B})$

$\clubsuit$ $aln(x) = ln(x)^a$

$\clubsuit$ $ln(A) + ln(B) = ln(AB)$

Using above ideas we can solve the Problem :

⇒ $\frac{3}{8}ln(x + 3) = ln(x + 3)^\frac{3}{8}$

⇒ $ln(x - 3) - ln(x + 3)^\frac{3}{8} = ln[\frac{(x - 3)}{(x + 3)^\frac{3}{8}}]$

⇒ $4ln[\frac{(x - 3)}{(x + 3)^\frac{3}{8}}] = ln[\frac{(x - 3)}{(x + 3)^\frac{3}{8}}]^4 = ln[\frac{(x - 3)^4}{(x + 3)^\frac{3}{2}}]$

⇒ $\frac{1}{3}lnx + ln[\frac{(x - 3)^4}{(x + 3)^\frac{3}{2}}] = ln(x)^\frac{1}{3} + ln[\frac{(x - 3)^4}{(x + 3)^\frac{3}{2}}] = ln[\frac{\sqrt[3]{x}(x - 3)^4}{\sqrt{(x + 3)^{3}}}]$

Option 3 is the Answer

Which of the following terms appear in the expansion of (x+y)^10? The letter "a" in each term represents a real constant.

Vinvika [58]

ANSWER

$ax^4y^6$

$ax^3y^7$

$ax^6y^4$

EXPLANATION.

The given binomial is

$( {x + y)}^{10}$

One property about all the terms in this binomial expansion is that:

The degree of each term is 10.

$ax^4y^6$

degree=4+6=10

$ax^3y^7$

degree=3+7=10

$ax^6y^4$

degree=6+4=10

$ax^5$

degree=5+0=5

All the terms with degree 10 are the correct options

The graph shows a probability distribution. What is P(2.5≤X≤4)?

jeka57 [31]

Answer:

P(2.5≤X≤4) = 0,3125‬

Step-by-step explanation:

We know that the area under the curve of ANY probability distribution should not be greater than 1.

In this case, we now that 4P = 1, therefore, P=1/4. Where 'P' represents the height of the rectangle that represents the probability distribution.

The probability of P(2.5≤X≤4) will be given by the area of the following rectangle:

(4 - 2.5) × 1,5 = 0,3125‬

Therefore, P(2.5≤X≤4) = 0,3125‬
