Write an equation in which the quadratic expression 2x^(2)-2x-12equals 0. Show the expression in factored form and explain what

Mnenie [13.5K]

Answer:

Begin by factoring 2 out of 2x^2 - 2x - 12 equals 0:

2(x^2 - x - 6) = 0

2(x - 3)(x + 2) = 0. 2 is never zero, but x-3 and x+2 can each be set = to 0:

This results in x = 3 and x = -2. The equation is true for these two x-values.

Hope this helped :3

Q1: Payments of $ 670 are being made at the end of each month for 5 years at an interest of 8% compounded monthly. Calculate the

zhuklara [117]

Answer:

$50,281.04

Step-by-step explanation:

5 years is equivalent to (5 × 12) = 60 months

Now, the first payment $670 is compounded for 60 months at the rate of $\frac{8}{12} = 0.667$ % monthly interest.

So, it will become $670(1 + \frac{0.667}{100})^{60} = 670(1.0067)^{60}$ .

Similarly the second payment of $670 will become $670(1.0067)^{59}$

Therefore, in this way after 60 months i.e. 5 years the total sum will be

= $670 + 670(1.0067)^{1} + 670(1.0067)^{2} + 670(1.0067)^{3} + ........ + 670(1.0067)^{59} + 670(1.0067)^{60}$

= $670[1 + (1.0067) + (1.0067)^{2} + (1.0067)^{3} + ....... + (1.0067)^{59} + (1.0067)^{60} ]$

= $670[1 \times \frac{(1.0067)^{61} - 1 }{1.0067 - 1} ]$

= $50,281.04 (Answer)

{Since, the sum of the G.P. series $1 + r + r^{2} + r^{3} + .......... + r^{n} = 1 \times \frac{r^{n + 1} -1}{r - 1}$ }

Megan and her brother Seth are saving up to buy a DSLR camera. Seth has

bazaltina [42]

Answer:

Meghan's weekly allowance is $60

Step-by-step explanation:

The first thing you need to do is know how much the camera is and how much Seth has already. If Seth already has $299.99 and the camera costs $699.99, you need to work out how much more you need.

699.99-299.99=400

$400

You need $299.99 more so you divide that by 5

59.998

Money is in 2 decimal point so you round to two.

Which gives you 60

That way, Meghan has $60 a week

What is the domain of the following points? Group of answer choices {-4, 1, 4} {-4, -1, 1, 4} {-1, 4, 1} {1, 4}

TiliK225 [7]

The domain of the relation shown in the graph is -4 <= x <= 4

<h3>How to determine the domain of the relation shown in the graph?</h3>

The complete question is added as an attachment

The relation on the graph is an ellipse function.

The domain is the set of x values the function can take

From the graph, we have the following x values

Minimum x value = -4
Maximum x value = 4

This means that the domain of x in the graph is -4 <= x <= 4

Hence, the domain of the relation shown in the graph is -4 <= x <= 4
