Which answer describes the transformation of f (x) = x^2 −1 to g(x)=(x+2)^2−1 ?

1 answer:

7 0

Answer: A horizontal translation 2 units to the left

In this case, we are changing the variable x before it is being squared. This will have the effect of changing the input of the function. Imagine input 2 into the equation. Your first step would be to add 2. Therefore, you would need to start with a negative 2 to get us back to 0, or the beginning.

Since -2 is to the left of 0, the graph is moving 2 units to the left.

How many times bigger is 3.45×10⁹ than 0.5×10⁴

son4ous [18]

3449995000 is what I got, I did 3.45x10^9 and then used that number and subtracted the answer from 0.5x10^4 to get the final answer, if that makes any sense.

HELP ME PLEASE

yuradex [85]

Answer:

368 milliliters.

Step-by-step explanation:

Compound A + Compound B = 1 drug

4 + 7 = 1 drug

11 milliliters = 1 drug, so 1012 milliliters = 92 drugs

Multiply the compounds by the amount of drugs, e.g.

4 x 92 = 368 ( Compound A )

7 x 92 = 644 ( Compound B )

368 + 644 = 1012

368 milliliters of Compound A are needed to make 1012 milliliters of the drug.

Hope this helps :)

The altitude (i.e., height) of a triangle is increasing at a rate of 2 cm/minute while the area of the triangle is increasing at

aksik [14]

The formula for the area of a triangle is
$A=\frac{1}{2}bh$
$\rightarrow\frac{dA}{dt}=\frac{1}{2}(b\frac{dh}{dt}+h\frac{db}{dt})$

We are given:
$\frac{dh}{dt}=2$
$\frac{dA}{dt}=4.5$
$h=9.5$
$A=92$

Plug in:
$4.5=\frac{1}{2}(b*2+9.5\frac{db}{dt})$
We can find $b$ with:
$A=\frac{1}{2}bh\rightarrowb=\frac{2A}{h}=\frac{2*92}{9.5}=\frac{184}{9.5}$
So $4.5=\frac{1}{2}(2*\frac{184}{9.5}+9.5\frac{db}{dt})$
$\rightarrow9=\frac{368}{9.5}+9.5\frac{db}{dt}$
$\rightarrow9-\frac{368}{9.5}=9.5\frac{db}{dt}$
$\rightarrow\frac{db}{dt}=\frac{9-\frac{368}{9.5}}{9.5}\approx-3.130$

So the base is decreasing at a rate of 3.130 cm/minute.
