The answer is 7/10:
1/5 and 9/10 HAVE to have the same denominator for us to do this problem.
So: 5 and 10 have a multiplier in common: 2
So: 1/5 x 2/2 = 2/10
Then you subtract: 9/10 - 2/10 which equals to:
7/10!!!
Your welcome!!!

7. f(x) = Square root of quantity x plus nine. ; g(x) = 8x - 13 Find f(g(x)). (1 point) f(g(x)) = 2 Square root of quantity two
AlladinOne [14]

Answer:

f(g(x)) =

\sqrt{8x \:  -  \: 13}  \:  +  \: 9

Step-by-step explanation:

f(x) =

\sqrt{x}  \:  +  \: 9

g(x) = 8x - 13

f(g(x) =

\sqrt{8x \:  - 13}  \:  +  \: 9

Find the coordinates of each point ( I, J, K) after the given transformation.
Andrews [41]

Answer:

Your answer would be I= (2,-1) J= (2,-3) and K= (5,-2)

Step-by-step explanation:

By reversing the coordinates across the x-axis, you will reverse the y coordinate (ex. 4,1 will become 4,-1). If you reverse the coordinates across the y-axis, you will reverse the x coordinate.

What is the only unknown (variable) needed to find the volume of a sphere?
yuradex [85]

Sphere

The radius of the sphere is the only unknown variable need to find the volume of a sphere.

Step-by-step explanation:

Sphere is a geometrical three dimensional round figure with every point on its surface equidistant from its center. It is a three dimensional representation of a circle. A line which connects from the center to the surface is called radius of the sphere.The diameter of the sphere is the longest straight line which passes through the center of the sphere.

The volume of sphere is given by:

Volume of sphere(V) = \frac{4}{3}\pi r^{3} \\

where V is the volume of the sphere

r is the radius of the sphere

\pi = \frac{22}{7}  = 3.14

Hence the only unknown variable to find the volume of a sphere is the radius.

estimate 0.037854921 to the nearest hundredth express your answer as a single digit times a power of 10
Vilka [71]

To solve this problem you must apply the proccedure shown below:

1. Let's round the value to the nearest hundredth. As you can see, the digit 8 is in the thousandths place and is greater than 5, therefore, you must round up to 0.038.

2. Now express the value as a single digit times a power of 10, as following:

38x10^{-3}

Therefore, the answer is: 38x10^{-3}

What 2 numbers add to get 2 and multiply to 4
rusak2 [61]
Factor 4
4=1 times 4
2 times 2
they don't add to 2
set up equation
x+y=2
xy=4

first equation, subtract x from both sides
y=2-x
subsitute for y
x(2-x)=4
distribute
2x-x^2=4
add x^2
2x=x^2+4
subtract 2x
0=x^2-2x+4
use quadratic formula which is
if you have ax^2+bx+c=0 then
x=\frac{ -b+/-\sqrt{b^{2}-4ac} }{2a} so

1x^2-2x+4=0
a=1
b=-2
c=4
x=\frac{ -(-2)+/-\sqrt{(-2)^{2}-4(1)(4)} }{2(1)}
x=\frac{ 2+/-\sqrt{4-16} }{2}
x=\frac{ 2+/-\sqrt{-12} }{2}
we have \sqrt{-12} and that doesn't give a real solution
therefor there are no real solutions
but if you want to solve fully
x=\frac{ 2+/-2\sqrt{-3} }{2}
i=\sqrt{-1}
x=\frac{ 2+/-2i\sqrt{3} }{2}
x=1+/-i\sqrt{3}
x=1-i\sqrt{3} or x=1+i\sqrt{3} (those are the 2 numbers)
