Wittaler [7]

Answer:

6*10^-3 > 5*10^-3

Step-by-step explanation:

$6*10^{-3}\\6*\frac{1}{10^{3} }\\6*\frac{1}{1000}\\\frac{6}{1000}=\frac{3}{500}=0.006$

$5*10^{-3}\\5*\frac{1}{10^{3} }\\5*\frac{1}{1000}\\\frac{5}{1000}=\frac{1}{200}=0.005$

0.006>0.005, therefore, 6*10^-3>5*10^-3

The math club is fast becoming one of the most popular clubs on campus because of the fabulous activities it sponsors annually f

Sergeu [11.5K]

Answer:

The many members should the club expect to have 5 years from now is 167.

Step-by-step explanation:

The number of members in the club at present is, 45.

It is provided that each year the club's enrollment increases by 30%.

Compute the increasing rate as follows:

$Rate=1+0.3=1.3$

Then the number of members in the club after <em>n</em> years is given by the equation:

$Number\ of\ members\ after\ n\ years=45\times (1.3)^{n}$

Compute the number of members in the club after 5 years as follows: $Number\ of\ members\ after\ 5\ years=45\times (1.3)^{5}\\=45\times (1.3)^{5}\\=45\times 3.71293\\=167.08185\\\approx167$

Thus, the many members should the club expect to have 5 years from now is 167.

Write an equation for a circle with a diameter that has endpoints at (7, –4) and (1, –10). Round to the nearest tenth if necessa

Black_prince [1.1K]

The standard form for the equation of a circle is :

(x−h)^2+(y−k)^2=r2 ----------- EQ(1)
where handk are the x and y coordinates of the center of the circle and r is the radius.
The center of the circle is the midpoint of the diameter.

So the midpoint of the diameter with endpoints at (7,-4)and(1,-10) is :

((7+(1))/2,(-4+(-10))/2)=(4,-7)

So the point (4,-7) is the center of the circle.

Now, use the distance formula to find the radius of the circle:

r^2=(7−(4))^2+(-4−(-7))^2=9+9=18

⇒r=√18

Subtituting h=4, k=-7 and r=√18 into EQ(1) gives :

(x-4)^2+(y+7)^2=18

I have no idea!!! Help??

Savatey [412]

Answer:

x<5

Open circle at 5 going to the left

x >1

Open circle at 1 going to the right

Step-by-step explanation:

7x -19 < 16

Add 19 to each side

7x -19 +19< 16+19

7x< 35

Divide by 7

7x/7 < 35/7

x<5

Open circle at 5 going to the left

9+3x>12

Subtract 9 from each side

9-9 +3x >12-9

3x >3

3x/3 >3/3

x >1

Open circle at 1 going to the right
