Answer:
The answer could be A) or D) because the zero acts as a place holder. Its a little easier to derive it if you have a bigger decimal
Step-by-step explanation:
Answer:
Exact form, p = 63/8
decimal form, p = 7.875
Mixed number form, p = 7 7/8
Step-by-step explanation:
Solve for p by cross multiplying
Answer:
Total time taken by walking, running and cycling = 22 minutes.
Step-by-step explanation:
Let the speed of walking = x
As given,
The distance of walking = 1
Now,
As 
⇒ Time traveled by walking = 
Now,
Given that - He runs twice as fast as he walks
⇒Speed of running = 2x
Also given distance traveled by running = 1
Time traveled by running = 
Now,
Given that - he cycles one and a half times as fast as he runs.
⇒Speed of cycling =
(2x) = 3x
Also given distance traveled by cycling = 1
Time traveled by cycling = 
Now,
Total time traveled = Time traveled by walking + running + cycling
=
+
+ 
= 
If he cycled the three mile , then total time taken =
+
+
= x
Given,
He takes ten minutes longer than he would do if he cycled the three miles
⇒x + 10 = 
⇒
⇒
⇒x =
= 12
⇒x = 12
∴ we get
Total time traveled by walking + running + cycling =
min
<u>Answer:</u>
The equation of a polynomial of degree 3, with zeros 1, 2 and -1 is 
<u>Solution:</u>
Given, the polynomial has degree 3 and roots as 1, 2, and -1. And f(0) = 2.
We have to find the equation of the above polynomial.
We know that, general equation of 3rd degree polynomial is

where a, b, c are roots of the polynomial.
Here in our problem, a = 1, b = 2, c = -1.
Substitute the above values in f(x)


So, the equation is 
Let us put x = 0 in f(x) to check whether our answer is correct or not.

Hence, the equation of the polynomial is 
Answer:
4 and 5
Step-by-step explanation:
If you mean what
falls into, you would get something in between 4 and 5.
We can solve this by first finding a square root that is higher than that, which is
and
.
If we go by that
falls in between 4² and 5².
