I don’t understand how to get x and y

Mathematics
1 answer:
DIA [1.3K]3 years ago
8 0

Answer:

x is approximately 7.97 or 8.0

y is approximately 6.9

Step-by-step explanation:

We have a triangle:

side a = y

side b = 4

side c = x

We can use the trigonometric function tangent which relates opposite and adjacent sides of the triangle in respect with a certain angle.

In this case we'll be using angle of 60º

y is opposite to 60º and 4 is adjacent

tan=\frac{opposite}{adjacent}

Solve for opposite;

opposite=adjacent*tan\\o=4*tan60\\o=6.9

This is the value of y.

To find x, we can use the pythagorean theorem.

c^2=a^2+b^2\\c=\sqrt{a^2+b^2} \\c=\sqrt{(4)^2+(6.9)^2} \\c=\sqrt{16+47.61}\\ c=\sqrt{63.61}\\ c=7.97

7.97 ≅ 8.0

A geometric sequence can be used to describe the population of rabbits on a
vlabodo [156]

Answer:

step 1

Find the average growth per year of the populations of rabbits farm A

Over the first 2 years

for t=0

numbers of rabbits=5 (is not exact)

for t=2

numbers of rabbits=40

average=[40-5]/2---------> 17.5

step 2

Find the average growth per year of the populations of rabbits farm B

Over the first 2 years

for t=0

numbers of rabbits=5 (is not exact)

for t=2

numbers of rabbits=30

average=[30-5]/2---------> 12.5

step 3

Compare the average growth per year of the populations of rabbits on both farms

farm A=17.5

farm B=12.5

the average rate of population growth of rabbits in farm A is greater than average rate of population growth of rabbits in farm B by about 5 rabbits per year.

therefore

the answer is the option C)

the average rate of population growth of rabbits in farm A is greater than average rate of population growth of rabbits in farm B by about 6 rabbits per year.

Why would someone want to factor a polynomial? Provide real-world examples of different questions we can answer or factors we ca
IgorC [24]

Factoring is a common mathematical process used to break down the factors, or numbers, that multiply together to form another number. Some numbers have multiple factors.

<u>Explanation:</u>

Factoring polynomials involves breaking up a polynomial into simpler terms (the factors) such that when the terms are multiplied together they equal the original polynomial. Factoring helps solve complex equations so they are easier to work with. Factoring polynomials includes: Finding the greatest common factor.

Factoring (called "Factorizing" in the UK) is the process of finding the factors: Factoring: Finding what to multiply together to get an expression. It is like "splitting" an expression into a multiplication of simpler expressions.

In circle P, if the radius is 3 cm, what is the length of arc AD?
umka21 [38]

Hello there.

We have for a circle that:

\ell=\alpha r

Where:

\ell is the measure of the arc

\alpha is the measure of the angle (radians)

r is the radius of the circle


In our case, we have \alpha = 120^\circ = \dfrac{120}{180}\pi = \frac23\pi ~rad

We have r = 3 cm, then:

\ell = (\frac23\pi )(3\ cm)\\ \\ \boxed{\ell = 2\pi~cm}
