Mathematics
1 answer:
RideAnS [48]2 years ago
3 0

Answer: The answer is $20

Multiply 400 by .05 or 5%.

If you wanna know 6 years it would be 536 usd

Explanation:

This would be an compound interest. Meaning that your gain every year would increase exponentially.

The equation to calculate this would be: Kn = K0⋅

(1+p100)n Kn is your savings after the period nK0 is your starting deposit p is the percentage n is the period of interest for your example we would have.

Kn=400⋅

(1+5100)6

Answer For A:  1:2 probability

Answer For B:  3:4 probability

Step-by-step explanation: Since there is 3 odds and 3 evens in a 6 sided dice, there is 1:2 probability for you to land on a even or a odd. But if you were to roll the dice twice, your probability rate increases by half. So your probability rate for winning if rolled twice is 3:4.

What is another name for the point located at (0 0)?
GenaCL600 [577]
The horizontal axis in the coordinate plane is called the x-axis. The vertical axis is called the y-axis. The point at which the two axes intersect is called the origin. The origin is at 0 on the x-axis and 0 on the y-axis.

Find the common difference, d, given that 8x-3, 4x+1, 2x-2 are consecutive terms of an
Pavel [41]

Answer:

B

Step-by-step explanation:

We are given that:

8x-3, \, 4x+1, \text{ and } 2x-2

Are consecutive terms of an arithmetic sequence.

And we want to determine the common difference <em>d</em>.

Recall that for an arithmetic sequence, each subsequent term is <em>d</em> more than the previous term.

In other words, the second term is one <em>d</em> more than the first term. So:

4x+1=(8x-3)+d

And the third term is two <em>d</em> more than the first term. So:

2x-2=(8x-3)+2d

We can isolate the <em>d</em> in the first equation:

-4x+4=d

As well as the second:

-6x+1=2d\Rightarrow \displaystyle -3x+\frac{1}{2}=d

Then by substitution:

\displaystyle -4x+4=-3x+\frac{1}{2}

Solve for <em>x:</em>

<em />\displaystyle -x=\frac{-7}{2}\Rightarrow x=\frac{7}{2}<em />

<em />

The isolated first equation tells us that:

d=-4x+4

Therefore:

\begin{aligned} \displaystyle d&=-4\left(\frac{7}{2}\right)+4\\&=-2(7)+4\\&=-14+4\\&=-10 \end{aligned}

Our final answer is B.

Factorise 6x²-14x-12​
maksim [4K]

Answer:

2(x - 3)(3x + 2)

Step-by-step explanation:

Given

6x² - 14x - 12 ← factor out 2 from each term

= 2(3x² - 7x - 6) ← factor the quadratic

Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 3 × - 6 = - 18 and sum = - 7

The factors are - 9 and + 2

Use these factors to split the x- term

3x² - 9x + 2x - 6 ( factor the first/second and third/fourth terms )

= 3x(x - 3) + 2(x - 3) ← factor out (x - 3) from each term

= (x - 3)(3x + 2)

Thus

3x² - 7x - 6 = (x - 3)(3x + 2) and

6x² - 14x - 12 = 2(x - 3)(3x + 2) ← in factored form
