Answer:

6.8yards/seconds

Step-by-step explanation:

Speed = Distance/Time

Given the following

Distance covered = 1232 yards

Time taken = 180 seconds

Substitute to get the speed

Speed  = 1232/180

Speed  = 6.84

Hence whirlwind's speed in yards per seconds to the nearest tenth is 6.8yards/seconds

Multiply binomails (x + 2) (3x+1)
Alika [10]

Answer:

The answer is 3x^2+7x+2

Step-by-step explanation:

Multiply each term of the second bracket with the first bracket.

We can write:

(x+2)(3x+1)= 3x(x+2)+1(x+2)

By multiplying the terms we get:

=3x^2+6x+x+2

Now simplify by combining like terms:

=3x^2+7x+2

Thus the answer is 3x^2+7x+2....

2BNP= GNP

BP+BNP=333

GP+GNP=225

GP= 225-2BNP

BNP=333-5(225-2BNP)

BNP=333-1125+10BNP

How do you find the rate of change
olga_2 [115]
If it's for a graph then I believe you just find the slope which you can do by taking two points and plugging them into this equation y-y
/
X-X

Example: (2, 4) and (6, 7) the first number is always x and the second is always y so if you plug those in the equation would look like this....

4-7
/
2-6

That would end up being
3
- ---- aka the rate of change
4


P.s. The slash and the four dotted lines together means division. Hope this helps

How do I write 76543 to the -4 power in simplest form?
Reika [66]

<u>Answer:</u>

<u />

So, I don't know how other teachers taught you, but I have a trick.

<u>Step-by-step explanation:</u>

<u />

Step 1:

Solve 76543^{4}

76543^{4} = 34325898917194100000

Step 2:

Now put 34325898917194100000 under 1, like this:

\frac{1}{34325898917194100000}

<em>Note: Whenever you have a negative power, the result of the exponent will always be a fraction under 1.</em>

<em />

Step 3:

Add the negative:

\frac{1}{34325898917194100000} becomes:

-\frac{1}{34325898917194100000}

Your answer is -\frac{1}{34325898917194100000}

I hope this helps!
