Q(x)=4x2-3x3+8x is it a cubic trinomial

Norma-Jean [14]

Answer:

Yes

Answer: x = 0

Step-by-step explanation:

Yes it is.

Down is the answer how to solve this equation and the steps.

Step 1 :

Equation at the end of step 1 :

qx - (((4 • (x2)) - 3x3) + 8x) = 0

Step 2 :

Equation at the end of step 2 :

qx - ((22x2 - 3x3) + 8x) = 0

Step 3 :

Step 4 :

Pulling out like terms :

4.1 Pull out like factors :

qx + 3x3 - 4x2 - 8x =

x • (q + 3x2 - 4x - 8)

Equation at the end of step 4 :

x • (q + 3x2 - 4x - 8) = 0

Step 5 :

Theory - Roots of a product :

5.1 A product of several terms equals zero.

When a product of two or more terms equals zero, then at least one of the terms must be zero.

We shall now solve each term = 0 separately

In other words, we are going to solve as many equations as there are terms in the product

Any solution of term = 0 solves product = 0 as well.

Solving a Single Variable Equation :

5.2 Solve : x = 0

Solution is x = 0

Solving a Single Variable Equation :

5.3 Solve q+3x2-4x-8 = 0

In this type of equations, having more than one variable (unknown), you have to specify for which variable you want the equation solved.

Answer: x = 0

Hope this helps.

In 1 h the minute hand on a clock moves through a complete circle, and the hour hand moves through 1 12 of a circle. Through how

Schach [20]

Answer:

3/2π and π/480

Step-by-step explanation:

The question given says that the minute hand on a clock moves through complete circle in 1 hour, that is 360° or 2π. It also says that the hour hand moves through 1/12 of a circle, that means 30° or π/6.

To know how many radians do the minute hand and the hour hand move between 1:00 p.m. and 1:45 p.m, it's necessary to calculate how many radians move them per minute.

Between 1:00 p.m. and 1:45 p.m 45 minutes have passed. With that information, the radians can be calculated using multiplication and division.

Minute hand: To know how many radians move the minute hand per minute division wil be used.

Movement in an hour/ minutes in an hour

2π rad/60 min= π/30 rad-min

That means the minute hand move π/30 radians in a minute.

Now, multiplication can be used to calculate how many radians move the minute hand in 1h.

(π/30 rad-min)(45 minutes)= 3/2π rad

The minute hand moves 3/2π radians between 1:00 p.m. and 1:45 p.m.

Hour hand: To know how many radians move the hour hand per minute division wil be used.

Movement in an hour/ minutes in an hour

2π rad/(60 min x 12 hours)= π/360 rad-min

That means the minute hand move π/360 radians in a minute.

Now, multiplication can be used to calculate how many radians move the hour hand in 1h.

(π/360 rad-min)(45 minutes)= π/8 rad

The minute hand moves π/8 radians between 1:00 p.m. and 1:45 p.m.

Calculate the HCF and LCM using prime factorisation 208 and 234

Doss [256]

The HCF and LCM OF 208 and 234 is 2 and 13 respectively.

Highest common factor is the highest factor that is common to two or more numbers. Lowest common factor is the smallest factor that is common to two or more numbers.

Prime factors of 208 = 2x 2 x 2 x 2 x 13
Prime factors of 234 = 2 x 3 x 3 x 13
LCM = 2
HCF = 13
