Answer:

B.) Binomial with a degree of 3.

Step-by-step explanation:

The degree is the highest exponent in the polynomial (3 in this case), it's a binomial because there are two terms.

B - binomial with a degree of 3

there’s two terms making it a binomial and it’s degree is 3 because 3 is the highest exponent. i just finished this unit :)

Let AB // ED , AB = 10 units, AC = 12 units, and DE = 5 units. What is the length of AD?

zheka24 [161]

Answer:

length of CD = 18 units.

Step-by-step explanation:

In ΔABC and ΔCED,

AB║DE and AD is a transversal line,

m∠ABC = m∠CED [Alternate interior angles]

m∠ACB = m∠DCE [Vertically opposite angles]

ΔABC ~ ΔCED [By AA property of similarity]

Therefore, by the property of similar triangles, corresponding sides will be proportional.

$\frac{AB}{DE}= \frac{AC}{DC}$

$\frac{10}{5}=\frac{12}{CD}$

CD = 6

Since, AD = AC + CD

AD = 12 + 6

= 18 units

Therefore, length of CD = 18 units.

Can someone please give me the answer I will mark u brilliant

otez555 [7]

Answer:

4. option A ---> m = 65h

Step-by-step explanation:

According to the question it states that,

m --> number of miles traveled.
h --> over hours

Now if we look at the table we need to find the starting point, or in other words, how much distance traveled in 0 hours. So we would divide miles / hours.

*Four hours, the variable in the question and in the table says n, but the answer choices says h, so I am saying h for hours just if you were wondering on it.*

distance (m) / hours (h)

130 / 2 = 65

195 / 3 = 65

325 / 5 = 65

455 / 7 = 65

So, our starting point, or numbers of miles traveled in 0 hours was 65. Now let us form an equation.

m = 65h

I would appreciate if you give me the brainlist or not. Hope this helps and stay safe, happy, an healthy, thank you :) !!

For the exponential equation <img src="https://tex.z-dn.net/?f=y%20%3D%203.4%280.66%29%5Ex" id="TexFormula1" title="y = 3.4(0.66

lisabon 2012 [21]

Answer:

Option: B is the correct answer.

B) Decay, y- intercept = 3.4, rate is 34%

Step-by-step explanation:

We are given an exponential equation as follows:

$y=3.4(0.66)^x$

We know that any exponential function of the type:

$y=ab^x$

is growth function if: b>1

and is a decay function if 0< b< 1

Hence, here we have: b=0.66<1

Hence, the function is a decay function.

Also, we know that the y-intercept of a function is the point where x=0

Hence, we take x=0

we have: $y=3.4\times (0.66)^0\\\\\\y=3.4$

Hence, the y-intercept is: 3.4

Also, the rate of a function is denoted by 'r'

where b=1-r

⇒ 0.66=1-r

⇒ r=1-0.66

⇒ r=0.34

Hence, the rate is: 34%

option: B is the correct answer.

HELP PLEASE ASAP!!! Khan Academy unit test!

Answer:

As=0.13

Step-by-step explanation:

If we have central angle we use this rule to find area of sector :

$As=\pi r^{2}(\frac{C}{360})$

C is central angle. r is radius.

$As=\pi *9*\frac{\frac{9\pi }{17} }{360} =\\\\As=\pi *9*\frac{9\pi }{17*360} =\\\\$

Evaluate :

$\frac{798.63}{6120}=0.13$
