The unit rate of the cost of different weight of pistachios as shown on the graph is $1.25 per pounds.

<h3>What is unit rate?</h3>

A unit rate is a rate where the second quantity is one unit . Therefore, the unit rate of the linear graph can be found as follows;

(2, 2.5)(4, 5)

unit rate = y₂ - y₁ / x₂ - x₁

x₁ = 2

x₂ = 4

y₁ = 2.5

y₂ = 5

unit rate = 5 - 2.5  / 4 - 2 = 2.5 / 2 = $1.25 per pounds

Pls help how do i solve for x in this equation??
evablogger [386]

Answer:

x = -2

Step-by-step explanation:

1. Square both sides
x^2 +3x + 6 = x^2
2. Subtract x^2 from both sides
3x + 6 = 0
3. Subtract 6 from both sides and divide by 3
x = -2

IM SORRY BUT I NEED THIS QUESTION TOO ASAP PLEASE
Paraphin [41]

Using proportions, it is found that the amount of the novel she would have read is:

D. 14/15.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.

She has finished 5/6 of the novel, and will have read more 1/10 in the next two days, hence the total amount read is given by:

\frac{5}{6} + \frac{1}{10} = \frac{25 + 3}{30} = \frac{28}{30} = \frac{14}{15}

Hence option D is correct.

What is the general equation of a cosine function with an amplitude of 3, a period of 4 pi, and a horizontal shift of negative p
liberstina [14]

The cosine function with the given characteristics is:

f(x) = 3*cos(x/2 - pi).

<h3>How to get the cosine function?</h3>

The general cosine function is:

f(x) = A*cos(kx + p)

Where A is the amplitude and p is the phase, then we know that:

A = 3

p = -pi

Then we have:

f(x) = 3*cos(kx - pi)

And the period is equal to 4pi, then we must have that:

k*(x + 4pi) - pi = k*x - pi + 2pi

k = 1/2

Then the function is:

f(x) = 3*cos(x/2 - pi).
