Determine whether abc ----> jgh is a reflection, translation, rotation, or glide reflection.

Usimov [2.4K]

From this picture you can calculate coordinates of triangles' vertices:
$A(-9,0),\ B(-6,-4),\ C(-3,0),\ J(8,0),\ G(5,4),\ H(2,0)$ .

Since

$\frac{-9+8}{2} = \frac{-6+5}{2}= \frac{-3+2}{2}=- \frac{1}{2}$ $\frac{0+0}{2}= \frac{-4+4}{2} = \frac{0+0}{2} =0$

you can conclude that points A, B, C are rotated by $180^0$ about the point (-0.5,0) to form points J, G, H, respectively.

Answer: A is correct choice.

The florida manatee population is 3,000 and is decreasing by 11% each year. Write a function for this situation.

True [87]

Answer:

$P=3000(0.89)^t$

Step-by-step explanation:

It was given that, florida manatee population is 3,000 and is decreasing by 11% each year.

We want to write a function for this situation.

Since the population is decreasing annually, it is modelled by:

$P=P_0(1-r\%)^t$

We substitute the give initial population and rate of decrease to get:

$P=3000(1-0.11)^t$

This simplifies to:

$P=3000(0.89)^t$

Solve the systems by elimination: <br><br> 8x-2y= -10<br> -4x+y= 5

Pachacha [2.7K]

Let's eliminate x. To achieve this, mult. the 2nd equation by 2, obtaining

-8x + 2y = 10. Now add this result to the first equation:

8x-2y= -10

-8x + 2y = 10

---------------------

The two equations actually represent the same line. Without an x- or a y-value, we cannot solve for the value of the other variable. There are infinitely many solutions.

The equation gives the speed at impact, V metres per second, of an object dropped from a height of h metres. SHOW WORK From what

devlian [24]

Answer:

h = 17.65 m

Step-by-step explanation:

The given equation gives the speed at impact :

$v=\sqrt{2gh}$

h is height form where the object is dropped

Put v = 18.6 m/s in the above equation.

$h=\dfrac{v^2}{2g}\\\\h=\dfrac{(18.6)^2}{2\times 9.8}\\\\h=17.65\ m$

So, the object must be dropped from a height of 17.65 m.
