Answer

3.027 × 10^7

I'm not the best at explaining but here is my attempt

You start with 30270000 you write the first number which is 3 then put a decimal and then put the rest of the numbers until the rest of the numbers are zeros..

3.027

Then put a × 10^

3.027 × 10^

And then the original number's digit count minus 1 is the number so 0270000 is 7 digits so the answer is

3.027 × 10^7

Sorry i'm horrible at explaining

Answer:

3.027 × 10^7

Step-by-step explanation:

30270000

We need to move the decimal until there is only one digit to the left of the decimal. So we move it 7 places to the left.The 7 becomes out exponent. When we move it to the left, the exponent is positive. If we had moved it to the right, our exponent would have been negative

3.0270000 * 10 ^7

We can drop the trailing zero's

3.027 * 10 ^7

Anna71 [15]

60.8 is 190% of 32

Divide 60.8 over 32:
$\frac{60.8}{32} = 1.9$

Convert the decimal into a percentage by dividing it over 100:
$1.9 \times 100 = 190$

Calculate the length of AB if A is the point (2,3) and B is the point (-2,0)

d1i1m1o1n [39]

Answer:

Formular for coordinate length:

$length = \sqrt{ {(x_{1} - x _{2} )}^{2} + {(y_{1} - y_{2})}^{2} }$

In considerance of coordinates given of A and B

$x _{1} \: \: is \: \: 2 \\ x_{2} \: \: is \: \: - 2 \\ y_{1} \: \: is \: \: 3 \\ y_{2} \: \: is \: \: 0$

therefore substitute:

$length = \sqrt{ { \{2 - ( - 2) \}}^{2} + {(3 - 0)}^{2} } \\ \\ = \sqrt{ {(2 + 2)}^{2} + {3}^{2} } \\ = \sqrt{ {4}^{2} + {3}^{2} } \\ = \sqrt{16 + 9} \\ = \sqrt{25} \\ \\ { \boxed{ \boxed{length \: \: is \: \: 5 \: units}}}$

F(x)=-2x+1; {-2,0,2,4,6} Find the range of the function for the given domain.

3241004551 [841]

Answer:

For the domain indicated, the range is {-11, -7, -3, 1, 5}

Step-by-step explanation:

Given the indicated domain of f(x) you have to replace the values in the function to find the range (the "y" values of the function).

f(-2) = 5

f(0) = 1

f(2) = -3

f(4) = -7

f(6) = -11.

So the range for this domain is {-11, -7, -3, 1, 5}
