How can I factorise expressions

Answers

Answer 1

Answer:

The first step of factorising an expression is to 'take out' any common factors which the terms have. So if you were asked to factorise x² + x, since x goes into both terms, you would write x(x + 1) . This video shows you how to solve a quadratic equation by factoring.

Find the simple interest and amount when principal = Rs. 6000, rate = 6% per annum and time = 4 years

Answers

Given:

Principal = Rs. 6000

Rate of simple interest = 6% per annum.

Time = 4 years

To find:

The simple interest and amount.

Solution:

Formula for simple interest:

[tex]I=\dfrac{P\times r\times t}{100}[/tex]

Where, P is principal, r is the rate of interest and t is the number of years.

Putting P=6000, r=6 and t=4, we get

[tex]I=\dfrac{6000\times 6\times 4}{100}[/tex]

[tex]I=60\times 6\times 4[/tex]

[tex]I=1440[/tex]

Now,

[tex]Amount=Principal+Interest[/tex]

[tex]Amount=6000+1440[/tex]

[tex]Amount=7440[/tex]

Therefore, the simple interest is Rs. 7440 and the amount is Rs 7440.

Let f(x)=18/1+3^e-0.1x What is the point of maximum growth rate for the logistic function f(x)? Show all work. Round your answer to the nearest hundredth

Answers

Answer:

(0, 4.5)

Step-by-step explanation:

*The equation can be put into Desmos, to find the point, but the work to prove it is here*

f(x)=c/1+Ae^-Bx

Y=C

C=18      A=3      -B=-0.1

*Replace x with 0 in the equation, so you know 0 is the x value, and it leads you to the y value*

f(0)=18/1+3e^-o.1(0)

= 18/1+3e^0

=18/1+3(1)

=18/1+3

=18/4

=4.5

x=0    y=4.5

Maximum growth rate = (x,y) --> (0, 4.5)

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.

let x be the other leg, then

x² + 13² = 21²

x² + 169 = 441 ( subtract 169 from both sides )

x² = 272 ( take the square root of both sides )

x = [tex]\sqrt{272}[/tex] ≈ 16.5 cm ( to the nearest tenth )

There are 20 students in the drama club. Next year, 5 students will leave the drama club and some students will join. If d is the number of students who will join the drama clibz write an expression to represent the total number of students in the drama club next year.

The expression showing the number of students in the drama club the next year is 15+d.

What is an expression?

Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.

Given that, there are 20 students in a drama club,

5 of them will leave in next year, and d students will join,

We are asked to construct an expression to represent the total number of students in the drama club next year.

So, the present number of students in the club = 20

After next year = 20-5 = 15

After the joining = 15+d

Hence the expression showing the number of students in the drama club the next year is 15+d.

B. 1
C. 9/4
D. 5/2

Answers

Answer:

9/4

Step-by-step explanation:

2(x - 10) + 4 = -6x + 2

2x - 20 + 4 = -6x + 2

2x - 16 = -6x + 2

8x - 16 = 2

8x = 18

x = 18/8 or 9/4

Answer:

the answer is C

Step-by-step explanation:
