Answer:
a. 4th degree binomial
b. 2nd degree trinomial
c. 3rd degree monomial.
Step-by-step explanation:
In order to find each of these, start by writing the degree based on the highest exponent. The work for a is done for you below.
5x^4 - 8
This means it is a 4th degree.
Now we can decide what the final word is based on how many terms there are. In this one there is 2, so we call it a binomial.
4th degree binomial.
Answer:
5
Step-by-step explanation:
First multiply 7 and 4
7 * 4 = 28
Then divide 140 by 28
140/28 = 5
Height is 5
Step-by-step explanation:
The statement
y varies directly as x is written as
<h3>

</h3>
So we have
<h3>y = kx</h3>
First of all we must find the relationship between them
when
x = 5 and y = 9
We have
9 = 5k
Divide both sides by 5

So the equation for the variation is

<h2>b).</h2>
when x = 15

We have the answer as
<h3>y = 27</h3>
<h2>c).</h2>
when y = 6

We have the answer as

Hope this helps you
Answer:
The required number of ropes is 9.
Step-by-step explanation:
The length of rope is 65 ft.
The distance to the base of cliff was 585 ft.
Let the number of ropes or same lengths did it take climber to reach descent be x.

Divide both sides of 65.


Therefore the required number of ropes is 9.
Answer:
f^-1(-47) = -5
Step-by-step explanation:
You want to find the value of x that gives f(x) = -47.
-47 = 8 + 11x
-55 = 11x
-5 = x
Then f^-1(-47) = -5.
