Simplify the expression. - (m m + 3n - 13)

natulia [17]

Answer:

$= - {m}^{2} - 3n + 13$

Step-by-step explanation:

$- (m \times m + 3n - 13)$

$m \times m = {m}^{1} \times m$

${m}^{1} \times {m}^{1} = {m}^{1 + 1} = {m}^{2}$

$- ( {m}^{2} + 3n - 13)$

$= - {m}^{2} - 3n + 13$

Which function pass through the points (1, 4), (2, 9), and (3, 16)?

swat32

ANSWER

$y= {(x+ 1)}^{2}$

EXPLANATION

The given points are:

(1, 4), (2, 9), and (3, 16)

It is obvious that the function is not linear because there is no constant difference among the y-values.

We can however manipulate the y-values to quickly identify the function.

$4 = {2}^{2} = {(1 + 1)}^{2}$

$9= {3}^{2} = {(2 + 1)}^{2}$

$16= {4}^{2} = {(3 + 1)}^{2}$

We can infer from the pattern that, the function is;

$y= {(x+ 1)}^{2}$

Forty students are In Science club. Of those 45% are girls. This percent increase 56% after new girls join the club. How many ne

stepan [7]

45% of 40 is 0.45×40=18 girls
if x girls join then 56% of 40+x is 0.56(40+x)=18+x
22.4+0.56x=18+x
put together like terms
4.4=0.44x
x=10 girls joined

The speed of light in a vacuum is 29,980,000,000

sweet [91]

Answer:

$\huge\boxed{\sf 2.998 \times 10^{10}}$

Step-by-step explanation:

Given number:

29,980,000,000

Rules:

Move the decimal point after the first non-zero digit. (after 2)
Here, we will move the decimal point 10 places to the left to move it after the first non-zero digit.
Since we move the decimal point 10 places, we will write the number as a multiple of 10¹⁰ (10 being the exponent).

The number will become:

2.998 × 10¹⁰

$\rule[225]{225}{2}$
