Answer:

Step-by-step explanation:

<em><u>As</u></em>,

Integers includes whole numbers, and negative of the whole numbers.

And Rationals includes every fraction, Integers and negative fraction.

<em><u>So,</u></em>

170, -25, and 74 are both Integers and Rationals.

But,

Only 3/10 is a fraction included only in rationals and not in Integers

The function f(x) is represented by the table below. What are the corresponding values of g(x) for the transformation g(x)=2f(x)

malfutka [58]

Answer:

see the explanation

Step-by-step explanation:

we know that

g(x)=2f(x)

Find the value of g(x) for the corresponding value of f(x)

1) For x=-6, f(x)=2

Substitute

g(x)=2f(x)

g(x)=2(2)=4

2) For x=-2, f(x)=2

Substitute

g(x)=2f(x)

g(x)=2(2)=4

3) For x=0, f(x)=6

Substitute

g(x)=2f(x)

g(x)=2(6)=12

4) For x=1, f(x)=3

Substitute

g(x)=2f(x)

g(x)=2(3)=6

4) For x=6, f(x)=-1

Substitute

g(x)=2f(x)

g(x)=2(-1)=-2

An internet start-up predicts its revenue by a straight-line method with a slope of $7000 per month. In its 6 th month it had re

Margarita [4]

Given that the method of revenue calculation is straight line method, the equation modeling this will be given by:
y=mx+c
where:
m=slope
x=time
c=initial value.
from our question:
slope,m=$7000
time=T
y(x)=R(t)
hence the formula after the sixth month will be:
R(t)=7000T+45000

Write the equation of the circle that has a center of (-7, 17) with<br> a radius of V19.

kipiarov [429]

I think your question seems to be :-

Write the equation of the circle that has a center of (-7, 17) with a radius of √19

So , as we know that the equation of circle with centre at <em>(h,k)</em> and <em>radius r</em> is given by ${\bf{(x-h)^{2}+(y-k)^{2}=r^{2}}}$ . Now , using same concept in this question ;

${:\implies \quad \sf \{x-(-7)\}^{2}+(y-17)^{2}=(\sqrt{19})^{2}}$

${:\implies \quad \bf \therefore \quad \underline{\underline{(x+7)^{2}+(y-17)^{2}=19}}}$

<em>This is the required equation of Circle </em>

a A hole in the shape of a hemisphere is carved into each face of a cube. The holes are identical and centered at the centre of

morpeh [17]

Diameter of each hemispheral holes = the diameter of a full sphere = side length of cube = 2 units.

<h3>What is a Hemisphere?</h3>

A hemishpere is half of a sphere. Thus, two hemispheres makes one full sphere.

Given the image as shown below, since the identical hemispheral holes are centered at the center of each fce and they touch each other at only one point, it means that two hemisphere meet to make one full sphere.

Therefore, the diameter of a full sphere = side length of cube.

Thus, diameter of each hemispheral holes = the diameter of a full sphere = side length of cube = 2 units.
