(9.1 × 109)(7.5 × 102) What is the exponent of the power in scientific notation?

sergejj [24]

Answer:

= The exponent is 12

Step-by-step explanation:

(9.1 × 10^9)(7.5 × 10^2)

When multiplying terms in scientific notation, we multiply the numbers in front and add the exponents

(a* 10^b) (c* 10^d) = ac * 10^(b+d)

(9.1 × 10^9)(7.5 × 10^2) = (9.1*7.5) * 10^(9+2)

=68.25 * 10^11

But this is not proper scientific notation. We can only have 1 number in front of the decimal. We need to move the decimal 1 place to the right. That adds 1 to the exponent.

=68.25 * 10^11 = 6.825 * 10^(11+1)

= 6.825 * 10^12

What is the counterclockwise rotation shown below? 13 pts.

AveGali [126]

Answer:

<u>270° around the origin</u>

Step-by-step explanation:

As shown at the graph

ΔABC is translated to ΔA'B'C'

A(0,3) , B(-2,2) , C(-1,1)

A'(3,0) , B'(2,2) , C'(1,1)

So, if the coordinate of the pre-image is (x,y)

The coordinate of the image will be (y, -x)

Which mean the rule will be (x,y)→(y,-x)

The previous rule is the rule of rotation 270° counterclockwise

So, the answer is <u>270° around the origin</u>

The difference between two trinomials is 5x2 + 11x − 16. If one of the trinomials is 3x2 − 2x + 7, then which expression could b

vredina [299]

Answer:

$2x^2+13x-23$

Step-by-step explanation:

The first trinomial is

$3x^2-2x+7$

Let the other trinomial be P.

Then

$P+3x^2-2x+7=5x^2+11x-16$

We make P the subject to obtain,

$P=5x^2-3x^2+11x+2x-16-7$

We simplify to obtain,

$P=2x^2+13x-23$

Hence the other trinomial is $2x^2+13x-23$
