How would you divide 1.2 divided by 9?

Without a calculator, you would do this:

You would want to multiply 1.2 by
1, 2, 3, 4, 5, 6, 7, 8, etc. to try to get the best possible average.
So, 1, 2, 3, 4, 5 won't work.

6 * 1.2 = 7.2
7 * 1.2 = 8.4
8 * 1.2 = 9.6

So right now you have 7, 9 - 8.4 = .6 leftover.

Now you'd take .6/1.2, which is .5 .

Combine 7 and .5 and you get...

Your Answer:
7.5

For A = {a,b}, determine A x P(A).
alex41 [277]

Answer:

Since A={a,b}, then P(A)=\{\emptyset, \{a,b\}, \{a\}, \{b\}\}. Remember that the Cartesian Product of two sets A, B is defined by

A\times B=\{(x,y): x\in A \text{ and } y\in B\}. Then

A\times P(A)=\{(a,\emptyset),(a,\{a,b\}),(a,\{a\}), (a,\{b\}), (b,\emptyset),(b,\{a,b\}),(b,\{a\}), (b,\{b\})\}

HELLLPPPP FASTTTTT !!!!!!! When working with scientific Notation What does a negative exponent let you know about the size of th
Nimfa-mama [501]

Answer:

A negative exponent means that the number will be a decimal.

so 4 X 10^-9   (-9 being the exponent of 10)

the answer to this equation would be 0.000000004 because the decimal moves 9 times to the left

The function P(x) = 3x2 + 4x + 5,is dilated by the function I(x) = P(2x). Write the new function I(x).
kow [346]

Answer:

I(x) = 12x² + 8x + 5

Step-by-step explanation:

* Lets talk about the solution

- P(x) is a quadratic function represented graphically by a parabola

- The general form of the quadratic function is f(x) = ax² + bx + c,

  where a is the coefficient of x² and b is the coefficient of x and c is

  the y-intercept

- To find I(x) from P(x) change each x in P by 2x

∵ P(x) is dilated to I(x) by change x by 2x

∵ I(x) = P(2x)

∵ P(x) = 3x² + 4x + 5

∴ I(x) = 3(2x)² + 4(2x) + 5 ⇒ simplify

∵ (2x)² = (2)² × (x)² = 4 × x² = 4x²

∵ 4(2x) = 8x

∴ I(x) = 3(4x²) + 8x + 5

∵ 3(4x²) = 12x²

∴ I(x) = 12x² + 8x + 5

The equation of the line with slope -3 that goes through the point (-9,-7) can be written in the form y=mx+b
katrin2010 [14]

Answer:y= -9x-25

Step-by-step explanation: Write the slope-intercept form of an equation of the line with slope -9 and passes through the point (-2, -7).

--------

Form:: y = mx + b

Solve for "b"::

-7 = -9*-2 + b

-7 = 18 + b

b = -25

-----

Equation:

y = -9x - 25

---------------

Cheers,

Stan H.

-----------

point slope formula

y-y1=m(x-x1)

y+7= -9(x+2). Notice that we are subtracting a negative, so we have to add.

 

y+7=-9x-18

y= -9x-25
