Answer:

9 ft

Step-by-step explanation:

the original proportion is 3 : 7

we can let the new width be 'x'

the new proportion would be x : 21

21 / 7 = 3 so then you multiply 3 by 3 as well to get your answer of 9 ft as the width

hope this helps and lmk if you have questions!!! <3

The equation cos(35o) =a/25 can be used to find the length of . What is the length of bc? Round to the nearest tenth
poizon [28]
The equation cos (35°) = can be used to find the length of one side of a triangle It could be the length of the altitude or the length of the base depending of which the angle 35° was assigned. But in order for us to proceed with the calculation, we also need the length of the hypotenuse since cos (x) are<span> equal to the length of the adjacent side divided by the hypotenuse. The answer is 20.5 </span>

1. Example of Fourth-degree trinomial<br> 2. Example of Cubic polynomial with four terms
borishaifa [10]
So, i think all you really need here is some definitions:
degree is the highest exponent that a polynomial has; a "fourth-degree" polynomial would have a highest exponent of 4.
a trinomial is a polynomial with 3 terms (tri means 3).
a cubic polynomial is a polynomial with an exponent of three.
terms are the values separated by signs in a polynomial; for example, in the binomial x - 1, both "x" and "-1" are terms.

with that info, an example of a fourth-degree trinomial is simply one with an exponent of 4 and 3 total terms: x⁴ + x² + 16 is one example, but there are maaaaaaaany examples you could create from it. x⁴ + x + 1 has a degree of 4 and three terms, so you can do whatever you want with it.

an example of a cubic polynomial with 4 terms could be x³ + x² + x + 1; x³ + 2x² + 27x + 119 is another. the most important thing for this one is that you list out x³, x², and x as well as a constant, because that's the only way to secure their placement in the polynomial without becoming like terms that combine and turn into fewer terms. you couldn't put two x² terms or multiple constants because they simplify into a single term.

What formula can be used to describe the sequence below?<br> -8,-5,-2,1,4...
ikadub [295]
This is just an arithmetic sequence because each term is a constant difference from the preceding term, called the common difference.

Any arithmetic sequence can be expressed as:

a(n)=a+d(n-1)  where a=initial term, d=common difference, n=term number

In this case a=-8 and d=3 so

a(n)=-8+3(n-1)  which you can simplify if you'd like

a(n)=-8+3n-3

a(n)=3n-11
