<span>b.9 x 10^4 is 18 times larger than 5 x 10^3
    This is a simple matter of floating point division. So let's do that. 9 x 10^4 / 5 x 10^3 First, divide the significands. Giving 9 / 5 = 1.8 And subtract the exponents 4 - 3 = 1 So the result of the division is 1.8 x 10^1 which is 18. So 9x10^4 is 18 times larger than 5x10^3. Now looking at the available options, it's obvious that only "b" is correct.</span>

Step-by-step explanation:

Can you explain how to do this math problem?
d1i1m1o1n [39]

Since the problem is 2x^2-5xy-y^3 we first have to plug in what the x and y stands for, once you do that your problem should look like this:

2(-3)^2- 5(-3)(-2)- (-2)^3

Now take the parentheses away and when you do that your signs change.

2x3^2-5x(-3)x(-2)-(-2)^3    

do it again with -5x(-3)x(-2)

2x3^2-30-(-2)^3

now do this with (-2)^3

2x3^2-30-(-8)

Now evaluate the power

3^2 becomes 9

2x9-30-(-8)

then change -(-8) to a positive since two negatives make a positive

2x9-30+8

Now multiply the numbers 2x9

18-30+8

Then do 18-30 which equals -12 then add 8

Now you are left with your answer:

<u>-4</u>


Hope this helps! :3

What is the area of a triangle whose vertices are D(3,3) , E(3,−1) , and F(−2,−5)?<br> ?= Unit ^2
Thepotemich [5.8K]
Length of DE = 3-(-1) = 4

SIDE DE is a vertical line 

horizontal distance between E and F is  3 - (-2) = 5

So the area of triangle DEF = 0.5 * 4 * 5 = 10 sq units

if you have installed 4000 linear feet of 8 inch water pipe how much will it hold when full? (answe is 10,543) i need help writi
GuDViN [60]

Answer:

768,000\pi\ in^{3}  

Step-by-step explanation:

we know that

The volume of a cylinder (water pipe) is equal to

V=\pi r^{2}L

In this problem we have

r=8/2=4\ in -----> the radius is half the diameter

L=4,000\ ft ----> convert to inches

L=4,000*12=48,000\ in

V=\pi (4^{2}48,000)=768,000\pi\ in^{3}

Write in standard form: 22.2 x 10^5
garri49 [273]
2220000
 
it just means that 22.2 needs to be multiplied by 10, 5 times, so just move the decimal five to the right.
