Please help me with my math I’m so bad at this

Mathematics
1 answer:
mojhsa [17]3 years ago

Answer:

9

Step-by-step explanation:

(-9)^1/3 * (-81)^1/3

We can rewrite -81 as 9 * -9

So it can be rewritten as:

(-9)^1/3 * (9*-9)^1/3

Since they are all raised to the 1/3, we can combine the bases:

(-9*9*-9)^1/3 =

(9*9*9)^1/3, because the two negatives turn into a positive:

So this is basically:

(9^3)^1/3 = 9^1 = 9

What is the distance between (8, -3), (4,-7)?
Papessa [141]

Answer:

4\sqrt{2} which is none of your choices....

Did you mean (8,-3) and (4,-7)?

Step-by-step explanation:

We need to first find the distance between the x's.

Then the distance between the y's.

The distance between the x's is 8-4=4.

The distance between the y's is -3-(-7)=4.

So the distance between two points (x_1,y1)\text{ and }(x_2,y_2) is \sqrt{(x_1-x_2)^2+(y_1-y_2)^2}.

So we already found x1-x2 and y1-y2 so now we have:

\sqrt{(4)^2+(4)^2}

\sqrt{16+16}

\sqrt{2(16)

\sqrt{16}\sqrt{2}

4\sqrt{2}

How are natural numbers, whole numbers and integers used in everyday life?
Nezavi [6.7K]
Natural numbers: Counting things! You look around your room and see an electronic device, then another, then another! You just counted to 3 using the natural numbers.

Whole numbers! You try to look for electronic devices and realise that they’re all gone. You have zero electronic devices, and you just used whole numbers.

You go online to find where your electronic devices went, and realise they were taken because you’re in debt to the bank so they took some of your stuff. You’re in negative numbers, and now you’ve used integers.

Two architects bid for a small government project, both
blondinia [14]

Answer:

10 hours

Step-by-step explanation:

let x be the total number of hours

Amazing design total charge = 45x+250

super structures total charge = 60x+100

both companies charge the same amount when both equation equals

45x+250=60x+100

60x-45x=250-100

15x=150

x=10

therefore at 10 hours both companies will charge the same amount
