i dont know how to solve this questions without a graphing on a calculator but i can't use calculator for this question pls help
Answers
Answer:
D
Step-by-step explanation:
When the denominator is equal to 0, the function doesn't exist. So factor the bottom, luckily its already partially factored.
(x^2 + 8x + 12) = (x+2)(x+6)
So now the denominator is (x+2)(x+6)(x-3)
The function doesn't exist when x = -2, -6, 3
Now we know there are 3 total discontinuities.
A and B can be eliminated
Since there is an (x+2) on the top and the bottom, they don't affect the shape of the function, but only causes a removable discontinuity when x = -2.
However, (x+6) and (x-3) are only on the bottom, so they DO change the shape, so they are non-removable
The answer therefore is 1 removable and 2 non-removable; D
Answer:
We have 1 removable discontinuity and 2 non-removable discontinuities
Step-by-step explanation:
Note that
[tex]x^2+8x+12 = (x+2)(x+6)[/tex]
Initially, we have discontinuities at
[tex]x = -2; x = -6; x = 3[/tex]
Considering
[tex]f(x)=\dfrac{(x+2)(x-6)}{(x^2+8x+12)(x-3)}[/tex]
But
[tex]\dfrac{(x+2)(x-6)}{(x^2+8x+12)(x-3)}= \dfrac{(x+2)(x-6)}{ (x+2)(x+6)(x-3)}= \dfrac{(x-6)}{ (x+6)(x-3)}[/tex]
We have now two discontinuities at
[tex]x = -6; x = 3[/tex]

On a map, 9 cm represents 15 miles. If the distance between two cities on the map is 15 cm, how many miles separate the cities?
Answers
Answer:
15 cm on the map is equal to 25 miles.
Step-by-step explanation:
Given that,
On a map, 9 cm represents 15 miles.
The distance between two cities is 15 cm. We need to find the distance in miles.
9 cm = 15 miles
[tex]1\ cm=\dfrac{15}{9}\ \miles[/tex]
So, 15 cm is equal to,
[tex]15\ cm=\dfrac{15}{9}\times 15\ miles\\\\=25\ miles[/tex]
So, 15 cm on the map is equal to 25 miles.

21. Tom buys a DVD player on 12 monthly payments. The cash price is $600. He pays
* 10% deposit and the store charges 9% interest.
(a) How much is each payment?
(b) Total amount Tom pays for the DVD player?
Answers
Answer:
Each monthly payment is $ 49.05, and in total Tom paid $ 648.60.
Step-by-step explanation:
Given that Tom buys a DVD player on 12 monthly payments, whose cash price is $ 600, and he pays a 10% deposit and the store charges 9% interest, to determine how much is each payment and the total amount Tom pays for the DVD player the following calculations must be performed:
600 - 600 x 0.1 = 540
540 x 1.09 = 588.6
588.6 / 12 = 49.05
Thus, each monthly payment is $ 49.05, and in total Tom paid $ 648.60.

How many triangles can be constructed with side lengths of 9.6 cm, 11.6 cm, and 21.2 cm?
0

NEED DIS ANSWER NOW PLZZZ
Answers
Answer: A) 0 triangles
============================================================
Explanation:
Adding up the two smaller sides gets us 9.6+11.6 = 21.2, but this result is not larger than the third side of 21.2
For a triangle to be possible, we need to be able to add any two sides and have the sum be larger than the third remaining side. This is the triangle inequality theorem.
I recommend you cutting out slips of paper with these side lengths and trying it out yourself. You'll find that a triangle cannot be formed. The 9.6 cm and the 11.6 cm sides will combine to form a straight line that is 21.2 cm, but a triangle won't form.
As another example of a triangle that can't be formed is a triangle with sides of 3 cm, 5 cm, and 8 cm. The 3 and 5 cm sides add to 3+5 = 8 cm, but this does not exceed the third side. The best we can do is form a straight line but that's not a triangle.
In short, zero triangles can be formed with the given side lengths of 9.6 cm, 11.6 cm, and 21.2 cm

bought the shares for a total of $480.75
so you’re going to multiply $3.75 by 120 shares since that’s how much they cost each and that gives you $450 cost so then you subtract the $480.75 from $450.00 which is the cost of the shares and that gives you $30.75 in total
