Answer:
393
Step-by-step explanation:
my best sum is 393 but this equation is impossible.
1. I understood that "2" in writing "f(x)=log2x" it's a the base of a logarithm.2. I understand that this equation must be written like this "2^(2y)=4", because else the problem lose the meaning.So, for the first, we must to remember what is a logarithm?Logarithm - a number that shows how many times a base number (such as ten) is multiplied by itself to produce a third number (such as 100).In simple terms: Logarithm it's the DEGREE that we must use for a base, to recieve argument.Now let's look at our equation.2^(2y)=4, let's make some changes.By property of degrees:2^(2y)=(2^2)^y.(2^2)^y=44^y=4y=log_{4}4
For find the results in the graph, we need to calculate the value of argument, wich we will search in graph.y=los_{2}x For use this graph we need to change our equation, to bring the equation to the form with such base. For that, we will use the properties of logarithms.log_{4}4=Log_{(2^2)}4=Log_{2}4^(1/2)=log_{2}2.Now for recieve the value of Y, we must to find "2" in axis OX, to build the line at right angle (from axis) into the graph. After that, we turn to axis OY at right angle, and we make the line to axis OY. In result we have the value on the axis OY, it's will be the desired value. And it must be 1.
Answer:
90 notebooks and folders
Step-by-step explanation:
Find the least common multiple (LCM) or 18 and 15!
18 x 5 = 90
15 x 6 = 90
Therefore, your answer is 90
Hope this helps!
Answer: 0.64sec
Step-by-step explanation:
h= -16t2 + t + 6
a= -16 b=1 c= 6
Using the quadratic equation formular
X = -b ± √b2 - 4ac / 2a
X= -1 ± √1^2 - 4(-16)6 / 2(-16)
=-1 ±√1+384 / -32
= -1 ±√385 / -32
Either X = -1 + 19.62 / -32
= 18.62 /-32
=-0.58 sec
Or X = -1-19.62 / -32
= -20.62 / -32
= 0.64sec
Since there is no negative time, therefore our answer is 0.64sec
Answer:
Step-by-step explanation:
If you wanna decrease the number 10 by 90%, It's just 9. You simply need to multiply a/100 at the number you try to decrease by a%.
