Factorise the following.
Answer:
iii. (l + m - n)(l - m + n)
vi. (5a -b) ( 5b - a)
Step-by-step explanation:
iii. l² - (m - n)²
= (l + m - n)(l - m + n)
vi. 4(a+b)² - 9(a-b)²
= (2(a+b))² - (3(a-b))²
= (2(a+b) + 3(a-b)) (2(a+b) - 3(a-b))
= (2a+2b + 3a - 3b) (2a+2b - 3a + 3b)
= (5a -b) ( 5b - a)
Q. 1) l²- (m - n)²
=(l - m + n)(l + m - n)
Q.2) 4(a+b)²- 9(a-b)²
= [(2(a+b))²- (3(a-b))²]
=[2(a+b)+3(a-b)][ 2(a+b)-3(a-b)]
=[2a+2b+3a-3b][2a+2b-3a+3b]
=[5a-b][5b-a] ]
find the equation of the exponential function represented by the table below : X Y
0. 0.02
1. 0.04
2. 0.08
3 0.16
Answer:
f(x) = 0.01 × 2^(x+1)
Step-by-step explanation:
0.02 = 0.01 × 2¹
0.04 = 0.01 × 2²
0.08 = 0.01 × 2³
0.16 = 0.01 × 2⁴
The equation of the exponential function is [tex]f(x) = 0.01 \times 2^{x+1}[/tex].
What are exponential functions?When the expression of function is such that it involves the input to be present as exponent (power) of some constant, then such function is called exponential function. There usual form is specified below. They are written in several such equivalent forms.
The equation in exponential form
y = A(Bˣ)
Since we are given as;[tex]f(x) = 0.01 \times 2^{x+1}[/tex]
Case 1 :
x =0, y = 0.02
0.02 = A (B⁰)
A = 0.02
Case 2:
x = 1, y =0.04
0.04 = 0.02(B)
0.04 /0.02 = B
B = 2
Case 3 :
x = 2, y =0.08
0.08 = 0.02(2²)
0.08 = 0.08
Case 4 :
x = 3, y = 0.16
0.16 = 0.02(2³)
0.16 = 0.16

double the sum of a number and 3
Hey there!
Your answer is 2(n + 3)
"Double" represents multiplying by two. Also, "sum of a number and 3" represents the addition of 3 and a number, so we could put "n + 3". Since we are doubling the sum, it would be "2(n + 3)"

What are the zeros of equations?Zeros of an equation is defined as the value of the independent variable where the equation or function gives zero.
Here,
To calculate the zeros of a function from a graph, you need to identify the points where the graph intersects the x-axis. The x-values of these points of intersection are the zeros of the function.
Based on the graph provided, it can be concluded that the zeros of the function occur at x = 0 and x = 5, and therefore, option C is the correct answer.

f(x)=18,000(1-0.012)^x ; x represents the number of years since the car started to depreciate and 18,000 = the initial value of the car. What year will you recieve the car when the car value drops below $2,000? Please do a step by step
Answer:
Given
f(x)=18,000(.88)^x
We need to find the value of x when f(x) <2000
2000 = 18000(0.88)^x
0.88^x 2000/18000
0.88^x 1/9
• x = log (1/9) / log (0.88)
• x= 17 (rounded down)
After 17 years or during year 18 the car value will drop below $2000
