Answer:

2 x 10^5

200,000 / 10 = 20,000

20,000 / 10 = 2,000

2,000 / 10 = 200

200 / 10 = 20

20 / 10 = 2

I divided 200,000 by 10 five times to get a number less than 10.

So, 5 is going to be the exponent.

Question Explanation:

In other words you can write 200,00 using a whole number and a power 10 using scientific notation!

In scientific notation you want a number less than 10 multiplied by 10 to the power of a number.

Solution:

200,000 / 10 = 20,000

20,000 / 10 = 2,000

2,000 / 10 = 200

200 / 10 = 20

20 / 10 = 2

I divided 200,000 by 10 five times to get a number less than 10.

So, 5 is going to be the exponent.

Answer:

both (x - 5) and (x - 3) are factors of x^2  - 2x + 15

Step-by-step explanation:

Please write this all on one line:  x^2  - 2x + 15.

Recognize that 3*5 = 15.  Possible factors of x^2  - 2x + 15 are thus (x - 5) and (x + 3).  Multiplying these together results in x^2  - 2x + 15, so we have verified that both (x - 5) and (x - 3) are factors of x^2  - 2x + 15.

f(x) = x² - 2x + 15

This function f(x) will have the negative "discriminant" in root ; thus forming complex roots

So this function has no rational roots

Answer:

c

Step-by-step explanation:

you score is 20, including bonus points. x=scor without bonus. that means that your normal score plus the bonus equals 20. so x +2=20

Answer:

what is the question

Step-by-step explanation:

i cant see any question marks

Answer:

hope this helps

Step-by-step explanation:

We are given the an area of

173.6 cm

and a height of 9 cm.

We also know that the formula for area is lw, meaning we can substitute the area for lw

in the volume formula.

Now let's plug in what we know into the formula and solve for the volume:

V=(173.6 cm2)(9 c)=1562.4 cm3 The volume of the rectangular prism is

1562.4 cm3

.

Answer:

-9x^2 + 12x + 5

Step-by-step explanation:

I'm assuming you meant (3x – 2)^2.  The " ^ " indicates exponentiation and is required.  We then have:

9 - (3x – 2)^2, which, when expanded, is

9 - (9x^2 -12x + 4), or:

-9x^2 + 12x + 5

Answer:

x = -3/7

Step-by-step explanation:

5(x + 3) = -2(x - 6)

Multiply the values on the outside of the parenthesis by what is on the inside.

5x + 15 = -2x + 12

Combine like terms by bringing them over to the other side using the necessary operation (addition or subtraction).

Bring -2x over to the left side by adding it to 5x.

5x + 2x = 7x

Bring 15 over to the right side by subtracting it from 12.

12 - 15 = -3

Now we have:

7x = -3

We need to get the x all by itself, so we divide both sides by 7.

7x/7 = x

-3/7 cannot be simplified further, so it is left as -3/7.

5 × 10²

Step-by-step explanation:

2 × 10^-3/4 ×10^-6

= 2/4 × 10^-3 - -6

= 1/2 (10^-3 + 6)

= 1/2 ×(10^3)

= 0.5 × 10^3

= 500

= 5 × 10²

Answer:

180

Step-by-step explanation:

40% are not 6th graders

10% of 450 if 45

there are four 10 percents in 40%, so 45 x 4 = 180

Answer:

2x - 2y

Step-by-step explanation:

P = 7x + 2y

P =a + b + c

7x + 2y = 2x + y +3x - 5y + c

7x + 2y - 5x - 4y

= 2x - 2y

Answer:

option (B) 33 is right answer

Answer:

Step-by-step explanation:

According to Supplementary Angle sum,

104° + x + x + 10° = 180°

=> 2x + 114 = 180

=> 2x = 180 - 114

=> 2x = 66

[tex] = > x = \frac{66}{2} [/tex]

=> x = 33 (Ans)

Answer:

3.27

Step-by-step explanation:

Let us assume that the values are the side of a right triangle where;

Hypotenuse = 6 (longest)

Angle of elevation = 33 degrees

Required

x = opposite side

Using the trig identity

Sin theta = opp/hyp

Sin 33 = x/6

x = 6sin33

x = 6(0.5446)

x = 3.27

Hence the value of x is 3.27

Note that the values of the sides are assumed.

Answer:

(13/2)^27

Step-by-step explanation:

First note that ( )^0 = 1, so we need not bother with the last term.

Next, note that

 (2/13)^(-6) divided by (2/13)^3 is (2/13)^(-9).

Finally, we must cube this last result.  We get:  (2/13)^(-9*3) = (2/13^(-27)

or

(13/2)^27

Note:  we're "evaluating" an algebraic expression here, not "solving it," since there is no equation here.
