Explanation Needed Find The Image Of (1 2) After A Reflection About Y=-1 Followed By A Reflection About

Answers

Answer 1

Answer:

A‘‘ (1,6)

Step-by-step explanation:

after a reflection about a horizontal line the x coordinates remain the same

the middle point of the segment AA’ lies on the line so it has y = -1

so we have

(y+y’)/2 = -1

y’ = -2 -y

y‘ = -2 -2 = -4

so A‘ (1,-4)

we can use the same reasoning to find the reflection about y = 1

x‘ = x

(y + y’)/2 = 1

y‘ = 2+4

y’ = 6

A‘‘(1,6)

I GIVE BRAIN LEST Which of the following is true about an

estuary?

It is all fresh water.

It is all salty water.

It has very few organisms.

It is affected by tides.

Answers

Answer:   D) It is affected by tides.

==========================================================

Explanation:

An estuary is where a river pours into the ocean. So that means fresh water mixes with salt water here. This allows us to rule out choices A and B.

According to NOAA, their site says "Estuaries are one of the most productive ecosystems in the world, so there is a great diversity of animals and plants that live there". In other words, a lot of plants and animals live here, so we can rule out choice C.

Choice D is the answer because tides do affect estuaries. This is simply because the ocean is pretty much right next to it, or attached to it. So it's expected that a high tide would cause the water level in an estuary to increase.

Answer:

it is affected by tides that's the conclusion I have come to

Step-by-step explanation:

The probability that it will rain this week and then rain next week will be the multiplication of the both the probability that it'll rain this week and probability that it'll rain next week.

Therefore, the answer will be:

= P(rain this week) × P(rain next week)

During a bean flipping experiment Fiona modeled her data using the function

f(t) = 4.127 (1.468) and Karl modeled his data with the function

k(t) = 0.897 (1.992) where t represents the number of trials and f(t) represents

the number of beans.

At what number of trials would Fiona and Karl have the same number of beans?

A.3

B4

C.5

0.6

Answers

Answer:

C.5

Step-by-step explanation:

Fiona:

After t trials, she would have:

[tex]f(t) = 4.127(1.468)^t[/tex]

Karl:

After t trials, he would have:

[tex]k(t) = 0.897(1.992)^t[/tex]

At what number of trials would Fiona and Karl have the same number of beans?

This is t for which:

[tex]f(t) = k(t)[/tex]

So

[tex]4.127(1.468)^t = 0.897(1.992)^t[/tex]

[tex]0.897(1.992)^t = 4.127(1.468)^t[/tex]

[tex]\frac{(1.992)^t}{(1.468)^t} = \frac{4.127}{0.897}[/tex]

[tex](\frac{1.992}{1.468})^t = 4.6[/tex]

[tex](1.35695)^t = 4.6[/tex]

[tex]\log{(1.35695)^t} = \log{4.6}[/tex]

[tex]t\log{1.35695} = \log{4.6}[/tex]

[tex]t = \frac{\log{4.6}}{\log{1.35695}}[/tex]

[tex]t = 5[/tex]

So the correct answer is 5 trials, option C.

Profit, P(x), is the difference between revenue, R(x), and cost, C(x), so P(x) = R(x) – C(x). Which
expression represents P(x), if R(x) = 2x4 – 3.2° + 2x – 1 and C(x) = x4 – x2 + 2x + 3?

Answers

Answer:

x^4 - 2.2x^2 - 4

Step-by-step explanation:

Given the following

R(x) = 2x4 – 3.2x^2 + 2x – 1 and C(x) = x4 – x2 + 2x + 3

Required

P(x)

Since P(x) = R(x) – C(x).

P(x) =   2x4 – 3.2x^2 + 2x – 1 – (x^4 – x^2 + 2x + 3).

Expand

P(x) = 2x4 – 3.2x^2 + 2x – 1 – x^4 + x^2 - 2x - 3

P(x) =   2x4 - x^4 - 3.2x^2 + x^2 + 2x - 2x -1 - 3

P(x) = x^4 - 2.2x^2 - 4

Hence the profit function is  x^4 - 2.2x^2 - 4
