Answer:

6 is the total number of roots

Alisiya [41]3 years ago
3 0

Answer:

6 roots

Step-by-step explanation:

f(x)=3x^6+2x^5+x4-2x^3

The number of roots is determined by the degree of the polynomial.  They may be real or complex.

Since this is a 6th degree polynomial, it will have 6 roots

f(x)=3x^6+2x^5+x4-2x^3

A colony of bacteria triples in link every 10 minutes. It's length is now 1 mm. How long will be in 40 minutes
Nuetrik [128]
If the bacteria is tripling every 10 minutes, that means the "rate of increase" on that period is 200%, so if say the current amount is "c", 200% of "c" is just 2c, so c + 2c is 3c, a tripled amount.

\bf \textit{Periodic Exponential Growth}\\\\
A=I(1 + r)^{\frac{t}{p}}\qquad 
\begin{cases}
A=\textit{accumulated amount}\\
I=\textit{initial amount}\to &1\\
r=rate\to 2\%\to \frac{200}{100}\to &2.00\\
t=\textit{elapsed time}\to &40\\
p=period\to &10
\end{cases}
\\\\\\
A=1(1 + 2)^{\frac{40}{10}}

2x2 - 12x + 10<br>what are the roots​
Tcecarenko [31]

Answer:

5 & 1

Step-by-step explanation:

We can use the quadratic formula to solve this:

Quadratic Formula = \frac{-b+-\sqrt{b^2-4ac} }{2a}

So we will have 2 answers (roots).

a is the coefficient of x^2 (2)

b is the coefficient of x (-12)

c is the constant (10)

Now, substituting, we get:

x = \frac{-b+-\sqrt{b^2-4ac} }{2a}=\frac{12+-\sqrt{(-12)^2-4(2)(10)} }{2(2)}=\frac{12+-\sqrt{64} }{4}=\frac{12+-8}{4}=\frac{12+-8}{4}=5,1

Hence the roots are 5 & 1

I need help with this ASAP.
Tomtit [17]

Answer:

Step 1 write the equation for perimeter (2L+2W =24)

Step 2 write the equation for area L x W = 32

Step 3 rewrite the equation of area so that one variable is on the right side L=32/W

Step 4 substitute L from step 3 into Equation 1 and simplify 2(32/W)+2W=24

Step 5 having found the width in step 4, use equation 3 to find the length

Step-by-step explanation:

<em>This is just added to show you how to solve but limit your answer to the answer above: rate brainliest please</em>

Area = L*W

Perimeter = 2(L+W)

So say L*W=32

and 2(L+W) = 24 which is 2L+2W =24

From area L=32/W

Then substitute it into perimeter

2(32/W)+2W=24 if you simplify this you get Width is 4 and 8

then length =32/W but W is 4 and 8 So L= 8 and 4

Meaning you have two options first rectangle is W=4 and L is 8, second triangle W=8 and Length=4
