The percentage increased by 42.86%.

To calculate the percentage increase:

First: work out the difference (increase) between the two numbers you are comparing.

Increase = New Number - Original Number

Then: divide the increase by the original number and multiply the answer by 100.

% increase = Increase ÷ Original Number × 100.

If your answer is a negative number then this is a percentage decrease.

Let T:R²->R² be a linear transformation ,and assume that T (1,2)=(-1,1) and T(1,-1)=(2,3)

zavuch27 [327]

Answer:

(-4,-1)

Step-by-step explanation:

We are given T(1,2)=(-1,1) and T(1,-1)=(2,3) and T is a linear transformation.

This implies for scalars a and b that

T(a(1,2)+b(-1,1))=aT(1,2)+bT(-1,1)

T((a,2a)+(-b,b))=a(-1,1)+b(2,3)

T((a-b,2a+b))=(-a,a)+(2b,3b)

T((a-b,2a+b))=(-a+2b,a+3b)

This means we should be able to solve the system below to find a and b for T(3,3):

a-b=3 and 2a+b=3

Add equations to eliminate b and solve for a:

3a=6

Divide 3 on both sides:

a=2

If a-b=3 and a=2, then b=-1.

Plug in a=2, b=-1:

T((a-b,2a+b))=(-a+2b,a+3b)

T((2--1,2×2+-1)=(-2+2×-1,2+3×-1)

T(3,3)=(-4,-1).

Which logarithmic equation is equivalent to 3^2 = 9?

noname [10]

Answer: $log_39=2$ is the logarithmic equation which is equivalent to $3^2=9$ .

Step-by-step explanation:

According to the laws of logarithms

$log_b\ x=n$ ,where b=base ,n,x all are positive

It can be written in exponential form such as

$x=b^n$

Now in the given question x=9 ,b=3 and n=2 such that it will equals to

$log_39=2$

Hence the logarithmic equation for $3^2=9$ is $log_39=2$ .
