Answer:
Here we have the domain:
D = 0 < x < 1
And we want to find the range in that domain for:
1) y = f(x) = x
First, if the function is only increasing in the domain (like in this case) the minimum value in the range will match with the minimum in the domain (and the same for the maximums)
f(0) = 0 is the minimum in the range.
f(1) = 1 is the maximum in the range.
The range is:
0 < y < 1.
2) y = f(x) = 1/x.
In this case the function is strictly decreasing in the domain, then the minimum in the domain coincides with the maximum in the range, and the maximum in the domain coincides with the minimum in the range.
f(0) = 1/0 ---> ∞
f(1) = 1/1
Then the range is:
1 < x.
Notice that we do not have an upper bound.
3) y = f(x) = x^2
This function is strictly increasing, then:
f(0) = 0^2 = 0
f(1) = 1^2 = 1
the range is:
0 < y < 1
4) y = f(x) = x^3
This function is strictly increasing in the interval, then:
f(0) = 0^3 = 0
f(1) = 1^3 = 1
the range is:
0 < y < 1.
5) y = f(x) = √x
This function is well defined in the positive reals, and is strictly increasing in our domain, then:
f(0) = √0 = 0
f(1) = √1 =1
The range is:
0 < y < 1

Which factor is greater 2/5 or 2/3 how can you tell which fraction is larger (looking for the explanation )
Answer:2/3
Step-by-step explanation The fractions 2/3 and 2/5 have the same numerator. The denominator 3 in the fraction 2/3 means that the unit has less parts, making the parts larger. Therefore, 2/3 is larger than 2/5 . The larger the denominator the smaller the fraction.

the product of 9 and t increased by the sum of t and 2
Answer:
9t + (t + 2)Step-by-step explanation:
the product of 9 and t is: 9•t
the sum of t and 2 is: t+2
increasing means adding, so:
the product of 9 and t increased by the sum of t and 2 would be:
9t + (t + 2) = 9t + t + 2 = 10t +2

Answer:
3⅞ is the answer to the question.
Step-by-step explanation:
The ten lightest tomatoes are in ¼, ⅜, ½, ⅝ and ⅞.
In ¼, there are 3 tomatoes, so that would be “¼×3=¾”.
In ⅜, there are 2 tomatoes, so that would be “⅜×2=¾”.
In ½, there are 3 tomatoes, so it would be “½×3=3/2”.
In ⅝, there is 1 tomato, so it would be “⅝×1=⅝”.
In ⅞, there is 1 tomato, so that would be “⅞×1=⅞”.
Now add all together:
¾ + ¾ + 3/2 + ⅝ + ⅞
= 5+5+7+6+8/8
= 31/8
= 3⅞

The division 4+2i/8-3i is performed by multiplying the numerator and denominator by (8+3i).
GivenThe division 4+2i/8-3i is performed by multiplying the numerator and denominator by
Expression; [tex]\rm \dfrac{4+2i}{8-3i}[/tex]
A complex conjugate is formed by changing the sign between two terms in a complex number i.e. a+ ib has conjugate a-ib and a- ib has conjugate like a+ ib.
The division 4+2i/8-3i is performed by multiplying the numerator and denominator by (8+3i).
[tex]=\rm \dfrac{4+2i}{8-3i}\\\\= \rm \dfrac{4+2i}{8-3i}\times \dfrac{8+3i}{8+3i}\\\\= \dfrac{(4+2i) \times (8+3i)}{(8)^2-(-3i)^2}\\\\= \dfrac{32+12i+16i+6i^2}{64+9}\\\\=\dfrac{32+28i+6i^2}{73}[/tex]

2. Given that the radius of the Earth is 6340 Km. calculate the Surface Acer of earth
Answer:
Step-by-step explanation:
The surface area of a sphere (which the earth is considered to be) = 4 pi r^2
pi = 3.14
r = 6340
Area = 4 * 3.14 * 6340 * 6340 = 504856736 square km.
You should either round this to 505,000,000 or express a value in scientific notation.

If a = 3 what is the value of b in the equation 2a+b=13? And can you explain?
Answer:
b=7
Step-by-step explanation:
Plug 3 into a since a=3.
2(3)+b=13
Then solve for 2(3)
6+b=13
Now isolate the b, so move the 6 to the other side. (Basically subtract 6 from both sides)
b=13-6
b=7

How do you find the point slope form for the points (2,7) and (-1,9)?
Answer:
y = -2/3 x + 25/3
Step-by-step explanation:
The slope = (y_2 - y_1) / (x_2 - x_1) = (9 - 7) / (-1 - 2) = -2/3.
Our equation needs to be in y = mx + b form.
We can plug in (2, 7) as our (x, y) and find b:
7 = -2/3 (2) + b
b = 7 + 4/3 = 25 / 3.
Therefore, our equation is y = -2/3 x + 25/3
Use the Equation(in the picture) and plug in your variables to find m(slope)
[tex]\frac{9-7}{-1-2} = \frac{-2}{3} = -0.67[/tex]
