What is the reflection image of P(0, 0) after two reflections, first across x = 4 and then across y = -3?

jek_recluse [69]

Answer:

The reflection image of P(0, 0) after two reflections is (8,-6)

Step-by-step explanation:

step 1

Find the coordinates of point P after reflection across x=4

we know that

The distance from point P to the line x=4 is equal to 4 units

(0,0) -----> (4+4,0) ----> (8,0)

The reflection image of P is (8,0)

step 2

Find the coordinates of point (8,0) after reflection across y=-3

The distance from point (8,0) to the line y=-3 is equal to 3 units

(8,0) -----> (8,-3-3) ----> (8,-6)

The number of bacteria present in a culture after t minutes is given as b=1000e^kt where k is a constant. If there are 8520 bact

Kryger [21]

To solve this problem, plug 8250 in for b and 15 in for t and then solve for k:

$8250=1000e^{15k}$

*Divide both sides by 1000*

$8.25=e^{15k}$

*Take the natural log (ln) of both sides*

2.1102=15k

*Divide both sides by 15*

0.1406=k

0.1406 rounds to 0.141 which is close to a. 0.143.

Hope this helps!!

What is the inradius of a triangle with side lengths 9, 40, and 41?

Mars2501 [29]

Answer: 20.5

Step-by-step explanation:

From the measure of the length of the sides of the triangle, 9, 40 and 41 we can infer that the triangle is a right angled triangle. 9-40-41 is a Pythagorean triplet.

In a right angled triangle, the circumradius is half the hypotenuse.

In the given triangle, the hypotenuse = 41.

Therefore, the circumradius is 41÷2= 20.5 units.
