Whats the answer

Answer:

− 0.85 y + 10.26

Step-by-step explanation:

The multiplication of the expression (5.23y + 3.8) and (2.7 - 1.6y) will be 8.041y + 10.26 - 8.368y²

When the relevant components and basic processes of a numerical method are given values, the expression's result is the result of the computation it depicts.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

The expression is given below.

⇒ (5.23y + 3.8) · (2.7 - 1.6y)

Simplify the expression, then we have

⇒ (5.23y + 3.8) · (2.7 - 1.6y)

⇒ 14.121y + 10.26 - 8.368y² - 6.08y

⇒ 8.041y + 10.26 - 8.368y²

The required equation that represent or approximate the population is:

[tex]\mathrm P(t) = 1,500 \times 3^{(1/7)}^t[/tex]

To represent the population, P, as a function of time in days, t, we need to find an exponential growth equation.

Since the population grows exponentially by a factor of 3 every week, we need to convert the weekly growth to daily growth.

Let's break down the problem step by step:

Now, we can represent the population, P, as a function of time, t, using the exponential growth equation:

[tex]\mathrm P(t) = \mathrm{Initial \ Population} \times \mathrm {Growth \ Factor}^t[/tex]

where:

Initial Population (Po) = 1,500 (given)

Growth Factor per day = [tex]3^{(1/7)[/tex]

So, the equation representing the population as a function of time in days is:

[tex]\mathrm P(t) = 1,500 \times 3^{(1/7)}^t[/tex]

Hence the required equation that represent or approximate the population is:

[tex]\mathrm P(t) = 1,500 \times 3^{(1/7)}^t[/tex]

Answer: A

Step-by-step explanation:

Answer:

52=8n +4

4=52-8n

are equivalent

Answer:

a, b, c, e

Step-by-step explanation:

4(2n + 1) = 52 is the same as 52 = 8n + 4 if you use distributive property.

4 = 52 - 8n is the same as 52 = 8n + 4. The 8n is just subtracted from both sides.

4n = 48 is not the same as 4(2n + 1) = 52 or 52 = 8n + 4 or 4 = 52 - 8n.

n = 6 is the solution to the equation so it is equivalent.

Answer:

A) P(chooses a blue pencil and then a red pencil) = 5/27

B) P(chooses yellow then blue) = 5/81

Step-by-step explanation:

She has 3 red pencils, 5 blue pencils, and 1 yellow pencil in her backpack

Thus;

total number of pencils = 3 + 5 + 1 = 9 pencils

A) probability that she chooses a blue pencil and then a red pencil;

P(blue) = 5/9

Now she puts it bag after choosing which means the sum is back to 8 pencils.

Thus, if she now chooses a red pencil, then P(red) = 3/9 = 1/3

Thus;

P(chooses a blue pencil and then a red pencil) = 5/9 × 1/3

P(chooses a blue pencil and then a red pencil) = 5/27

B) probability that Chloe chooses the yellow pencil and then a blue pencil;

Similar to A above;

P(yellow) = 1/9

P(blue) = 5/9

P(chooses yellow then blue) = 1/9 × 5/9

P(chooses yellow then blue) = 5/81

Answer:

Answer:

these are negative numbers

Step-by-step explanation:

sin(2x) - sin(x) = 0

Expand the first term using the double angle identity:

2 sin(x) cos(x) - sin(x) = 0

Factor out sin(x) :

sin(x) (2 cos(x) - 1) = 0

This leaves you with 2 cases that can be solved separately:

sin(x) = 0   or   2 cos(x) - 1 = 0

sin(x) = 0   or   cos(x) = 1/2

[x = 2nπ   or   x = π + 2nπ]   or   [x = π/6 + 2nπ   or   x = 5π/6 + 2nπ]

Answer: -0.833 (repeating decimal)

Step-by-step explanation: fg(x) means plug the g(x) equation into f(x), and for gf(x) it’s vice versa:

Fg(x) = 3x^2 - 1 + 2

Gf(x) = 3(x + 2)^2 - 1

First, we should simplify gf(x) to eliminate the (x + 2)^2:

3(x^2 + 4x + 4) - 1

3x^2 + 12x + 12 - 1

3x^2 + 12x + 11

Second, simplify fg(x) by solving -1 + 2: 1

Now, we can set the two equations equal to each other and solve:

3x^2 + 1 = 3x^2 + 12x + 11 (subtract 3x^2 from each other and 1 from 11)

-10 = 12x (Divide)

-0.8333... = x

To make sure this answer is correct, plug -0.833 into the original equations and set them equal to each other:

3(-0.833)^2 + 1 = 3(-0.833)^2 + 12(-0.833] + 11

3.083 = 3.083
