In the question it gives you the equation n = \frac{10}{3}t

I assume that "t" represents time

Since it asks you for 7 hrs you plug 7 in the place of "t" :

n = \frac{10}{3}(7)

This can also be written as:

n = \frac{10}{3}(\frac{7}{1})

so...

n = \frac{70}{3}

Which can be converted into decimal form of:

23.33333

This means that Olivia will sell about 23 boxes in 7 hr

Hope this helped!

H: (2, 14)

O: (4,15)

U: (6,14)

S: (2,10)

E: (6,10)

Step-by-step explanation:

the image on the grid is after doin x- 1 and y-7

to get the preimage do the inverse , x + 1 , y + 7

note- a coordinate is written as (x,y)

so, add 1 to all the x's and 7 to all the y's on the coordinates on the grid!

and sorry for asking but, if this is right could i please get a thanks & brainliest recently a moderator deleted ALL my answers (over 400 answers) causing me to lose over 3k points so id appreciate it alot thanks xoxo

The value of tangent x is given. Find sine x and cos x if x lies in the specified interval.
katrin2010 [14]

Answer:

sin x = 0.998

cosx = 0.046

Step-by-step explanation:

<u>Given that:</u>

tan x = 21

where interval of x is [0,\dfrac{\pi}{2}].

We know that the trigonometric identity for tan x is:

tan\theta = \dfrac{Perpendicular}{Base}

Comparing with:

tan x = \dfrac{21}{1}

Perpendicular = 21 units

Base = 1 unit

As per pythagorean theorem:

\text{Hypotenuse}^{2} = \text{Base}^{2} + \text{Perpendicular}^{2}\\

\Rightarrow \text{Hypotenuse}^2 = 21^2 +1^2\\\Rightarrow \text{Hypotenuse} = \sqrt{442} = 21.023\ units

interval of x is [0,\dfrac{\pi}{2}] so values of sinx and cosx will be positive because it is first quadrant where values of sine and cosine are positive.

We know that

sin\theta = \dfrac{Perpendicular}{Hypotenuse}\\cos\theta = \dfrac{Base}{Hypotenuse}

So, sine x :

\Rightarrow sinx =\dfrac{21}{21.023}\\\Rightarrow sinx = 0.998

Similarly, value of cos x :

\Rightarrow cosx =\dfrac{1}{21.023}\\\Rightarrow cosx = 0.046

The native bird population in a city is decreasing at a rate of 10% per year due to industrialization of the area by humans. The
Assoli18 [71]

Answer:

a_0 = 14000

a_{n} = 0.9a_{n - 1},~~ for ~n \ge 1

Step-by-step explanation:

Let "a" represent the population.

a_0 is the initial population.

a_n is the population at year n.

Since the population decreases 10% each year, that means that each year, the population is 90% of the previous year.

The initial population is 14,000.

Each year fater than, the population is 90% of the population of the previous year, or 0.9 time the population of the previous year.

a_0 = 14000

a_{n} = 0.9a_{n - 1}, ~~for ~n \ge 1
