Compare the numbers √11 and 3.7. Use the symbols <,>,or=.

Answers

Answer: Hi! here we want to compare the numbers $√(11)$ and $3.7$

and we need to use <,> or =

So the first thing i would look is the square root.

we know that $3^(2) = 9, 4^(2) = 16$

so 3< $√(11)$ <4

now we can see $3.7^(2) = (3 + 0.7)*(3 + 0.7) = (3*3 + 2*0.7*3 + 0.7*0.7) =(9 + 6*0.7 + 0.7*0.7)$

is easy to see that $0.7*6 \geq 0.5*6=3$

then $3.7^(2) = (9 + 0.7*6 + 0.7*0.7) > (9 + 3 + 0.7*0.7) > 9 +3 = 12$

so 3.7^2 > 12, and 12>11

then: $3.7 > √(11)$

You also can use a calculator, but i think this is not the idea of the problem.

2/3, 9/16, 0.52

Answers

First of all, you have to change the numbers in to the same form so I am going to change it to percentage.
2/3 = 0.66
9/16 = 0.56 So= 0.52, 9/16, 2/3
0.52

0.52, 9/16, 2/3 because if you turn the numbers to decimals you will get 9/16 as 0.5625, and 2/3 as 0.666 so it's 0.52, 9/16, 2/3.

How do I find the y-intercept of an equation in the form y=mx+by = mx + b?

Answers

That's exactly the form you want it in, because you can look at it and see
just about everything there is to know about the line.

y = mx + b

In that form, 'm' is the slope of the line, and 'b' is the y-intercept.

How many factors in the expression 8(x +4) (y +4) (z 2 + 4z + 7) have exactly two terms?

Answers

From the expression 8(x +4) (y +4) (z 2 + 4z + 7),
the factors are 8, (x+4), (y+4), (z^2 + 4z + 7) since each of these factors, when you divide that to the whole expression won't give a remainder.

Answer:

Only 2 factors have exactly two terms i.e, (x+4)(y+4)
