Answer:
Step-by-step explanation:
We need to find the error first.
We can do this by subtracting, to find the difference
2.4-1.9 = 0.5
the difference, or error, is 0.5
Now we find a percentage that describes how much more 2.4 is than 1.9
We can create an equation to solve this
2.4 = 1.9 Times x
Now we need to find the value of x
x= 1.2632
now we double check
1.9 Times 1.2632 = 2.4
Now we round to a whole number
1.2632 = 1
To convert a number to a percentage, you need to bring the number over a decimal point.
so 1 becomes .1, or 10 percent

<span>6(m-1)=3(3m+5)
6m-6=9m+15
6m - 9m = 15+6

Answer:
The equivalent expression is cosec2x
option B
Step-by-step explanation:
The correct question is ;
which expression is equivalent to sec2xcot2x?
Solution
Mathematically;
sec2x = 1/cos2x
cot2x = 1/tan2x
so we have
1/cos2x * 1/tan2x
recall that the product of tan and cos is sin
from the formula;
tan = sin/cos
so we have our final answer as;
1/sin2x
Kindly recall that ;
sin = 1/cosec
so therefore;
1/sin2x = csc2x
