Answer:

6 roots

Step-by-step explanation:

we know that

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

In this problem we have

$f(x)=3x^{6}+2x^5+x^4-2x^3$

The degree refers to the highest exponent of the polynomial

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

What percentage of 340 is 425?

beks73 [17]

Answer:

125%

Step-by-step explanation:

1. Set up the equation

425/340 = x/100

(percentages are out of 100 so this equation means 425 out of 340 is equal to a number out of 100)

2. Cross multiply

340x = 42500

3. Solve for x

x = 125

The volume of this regular pentagonal pyramid is 82.5 cubic meters. What is the height of the pyramid?

a_sh-v [17]

the height of the pentagonal pyramid is 5. 70 meters

<h3>Volume of a regular pentagonal pyramid</h3>

The formula for determining the volume of a regular pentagonal pyramid is given as;

V=5/12tan(54°)ha^2

Where

a is the base edge
h is the height

We have the volume to be;

volume = 82. 5 cubic centers

height = h

a = 5m

Substitute the values

$82. 5 = \frac{5}{12}$ × $tan 54$ × $h$ × $5^2$

$82. 5 = 0. 42$ × $1. 3764$ × $25$ × $h$

Make 'h' subject of formula

$h = \frac{82. 5}{14. 45}$

h = 5. 70 meters

The height of the pentagonal pyramid is 5. 70 meters

Thus, the height of the pentagonal pyramid is 5. 70 meters

Please help! <br><br> 6.2 divided by (2x + 1)= 2 1/3 divided by 4

guajiro [1.7K]

Answer:

x=2/3

Step-by-step explanation:

(2x+1)/2 = 2 1/3/4

Multiply 4 on both sides:

2x+1=2 1/3

Rewrite:

2x+1=7/3

Subtract 1 on both sides:

2x=4/3

Divide 2 on both sides:

x=2/3

Thus x=2/3

Hope this helps!
