x=8
Solution:First, multiply 12 times x, like so:12xNow, subtract 5:12x-5This expression is equivalent to 91:12x-5=91Now, add 5 to both sides:12x=91+512x+96x=8Hope it helps.
Do comment if you have any query.
[tex]12x-5 = 91\\\\\implies 12x = 91+5\\\\\implies 12x = 96 \\\\\implies x= \dfrac{96}{12}\\\\\implies x = 8[/tex]

20 workers can produce 1000 products in 10 hours.
Assuming the efficiency per worker remains the same, how many products can 15 workers produce in 5 hours?
Using proportions, it is found that 375 products are produced with 15 workers in 5 hours.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, we have that the rule of three are given as follows:
1000 products - 20 workers - 10 hours.
x products - 15 workers - 5 hours.
The measures are direct proportional, hence:
[tex]\frac{1000}{x} = \frac{20}{15} \times \frac{10}{5}[/tex]
[tex]\frac{1000}{x} = \frac{40}{15}[/tex]
Applying cross multiplication:
40x = 15(1000)
x = 15(1000)/40
x = 375.
375 products are produced with 15 workers in 5 hours.

Choose the inequality represented in the graph.
A. y ≤ x + 9
B. y ≥ -x + 9
C. y < -x + 9
D. y ≤ -x + 9
Answer:
D
Step-by-step explanation:
The solid line is y = -x + 9, and everything below it is shaded, so the correct sign is less than or equal to.
Putting the two pieces of information together, the equation you get is:
D. y ≤ -x + 9
Write the equation for each translation of the graph of y=|1/2x-2| +3.

The population sizes of many animal species rise and fall over time. Suppose that the population size of a certain species can be modeled by the following.
[tex]p(t) = 4096 - 1269cos(\frac{2\pi }{11} t)[/tex]
In this equation, p(t) represents the total population size and t is the time (in years). Suppose we start at t = 0 years.
During the first 11 years, when will the population size be 4700?
Do not round any intermediate computations, and round your answer(s) to the nearest hundredth of a year. (If there is more than one answer, enter additional answers with the "or" button.)
There are two answers
Solving the trigonometric equation, it is found that during the first 11 years, the population size will be of 4700 in 3.62 and 7.24 years.
What is the trigonometric equation for the population?It is given by:
[tex]p(t) = 4096 - 1269\cos{\left(\frac{2\pi}{11}t\right)}[/tex]
It will be of 4700 when p(t) = 4700, hence:
[tex]p(t) = 4096 - 1269\cos{\left(\frac{2\pi}{11}t\right)}[/tex]
[tex]4700 = 4096 - 1269\cos{\left(\frac{2\pi}{11}t\right)}[/tex]
[tex]604 = - 1269\cos{\left(\frac{2\pi}{11}t\right)}[/tex]
[tex]\cos{\left(\frac{2\pi}{11}t\right)} = -\frac{604}{1269}[/tex]
[tex]\cos{\left(\frac{2\pi}{11}t\right)} = -0.47596532702[/tex]
[tex]\cos^{-1}{\cos{\left(\frac{2\pi}{11}t\right)}} = cos^{-1}{-0.47596532702}[/tex]
Then:
[tex]\frac{2\pi}{11}t = 2.06685766[/tex]
[tex]t = \frac{11 \times 2.06685766}{2\pi}[/tex]
[tex]t = 3.62k, k = 1, 2, ...[/tex]
Thus:
t = 3.62 x 1 = 3.62
t = 3.62 x 2 = 7.24.
The population size will be of 4700 in 3.62 and 7.24 years.

Establish the identity.
sin theta * sec theta = tan theta
Answer:
In the picture is how to solve it
Step-by-step explanation:
Answer:
We are multiplying sin theta by sec theta, so we first start with valuing sec theta. Re-evaluate sec theta as sec(theta), and get the reciprocal.
[tex]sin(theta) * \frac{1}{cos(theta)}[/tex] <-- reciprocal
Combine sin() with the reciprocal of sec theta.
[tex]\frac{sin(theta)}{cos(theta)}[/tex]
Rewrite this combination as tan(theta)
[tex]tan(theta)[/tex]
Since the sides are equal, they count as an identity.
[tex]sin(theta) * sec(theta) = tan(theta)[/tex]
That said, sin(theta) × sec(theta) = tan(theta) is an identity.
