What is the degree of the following polynomial? 2x^7+4-3x^3+5x^8-4x

Mathematics

1 answer:

Stells [14]1 year ago

8 0

Answer:

Step-by-step explanation:

The degree of a polynomial is the same as its highest exponent. Even though this one is "out of order", per se, and starts with an exponent of 7, there is an exponent of 8, which is also the highest exponent in the polynomial. This is an 8th degree polynomial.

D is not right its a negative 8 so therefore it would be minus

Ilya [14]

I really dont understant your question. but you are right that negative 8 that it would be minus. In mathematics, a negative number is a real number that is less than zero. Negative numbers represent opposites. If positive represents movement to the right, negative represents movement to the left.

What multiplies to be 42 and adds to be 23?

Furkat [3]

A) x * y = 42 (or x = 42/y)
B) x + y = 23

B) 42/y + y = 23
42 + y^2 = 23y
y^2 -23y + 42 = 0

The numbers are 21 and 2

A cone has a radius of 5 ft and a height of 15 ft. It is empty and is being filled with water at a constant rate of 15 15 ft 3 f

kvasek [131]

Answer:

$\frac{dr}{dt}=0.11062ft/sec$

Step-by-step explanation:

From the question we are told that:

Radius $r=5ft$

Height $H=15ft$

Rate $R=15ft/3sec =5ft/s$

Surface Radius $R_{surf}=2.2ft$

Generally the equation for Volume is mathematically given by

$V=\frac{1}{3}\pi*r^2h$

Since radius to height ratio gives

$\frac{r}{h}=\frac{5}{15}$

$\frac{r}{h}=\frac{1}{3}$

$h=3r$

Therefore

$V=\frac{1}{3}\pi*r^2(3r)$

$V=\pi r^3$

Generally the equation for Change of Volume is mathematically given by

$\frac{dv}{dt}=\pi \frac{d}{dt}(r^3)$

$\frac{dv}{dt}=\pi 3*r^2 \frac{dr}{dt}$

$\frac{dv}{dt}=\pi 3*(2.2)^2 \frac{dr}{dt}$

$\frac{dr}{dt}=\frac{5}{45.62}$

$\frac{dr}{dt}=0.11062ft/sec$

What is median of 3 7 5 2 4 2 53 6 9 7 7 3 5 2 7 3 2 2 7

ludmilkaskok [199]

Answer:

Step-by-step explanation:

To find the median number of

3 7 5 2 4 2 53 6 9 7 7 3 5 2 7 3 2 2 7

Number them from least to greatest

2 2 2 2 3 3 3 4 5 5 6 7 7 7 7 7 9 53

Since this isn't an even numbered set, all we do is cancel each number out equally on both sides until only one number which should be in the middle is left. This gives you an answer of 5

Hope this helps!
