In this problem, you are asked to write a number in scientific notation. In figures, 78 million would look like this:

78,000,000

To write this to scientific notation, you have to move the decimal point to the left until you will get a number between 1 and 10.

Here, you will have to move the decimal point 7 times to get 7.8

The exponent of the scientific notation is the number of times you moved your decimal point. Since the movement of decimal point is going to the left, you will have a positive exponent.

The scientific notation would look like this:

7.8 x 10^7

That would be 7.8 * 10^7

DENIUS [597]
To find the resultant vector you need to add the horizontal and vertical components of each individual vector.
Cosine for horizontal, Sine for vertical.
v = \ \textless \ |v|cos \theta, |v| sin \theta\ \textgreater \
Where |v| is magnitude or length of vector.
Lets look at first ranger station. First vector has magnitude 4.5 with angle of 90.
Next has magnitude of 8.1 with angle of 125.
F_1 = \ \textless \  4.5 cos(90)+8.1 cos(125) , 4.5 sin(90) + 8.1  sin(125) \  \textgreater \
F_1 = \ \textless \ -4.646, 11.135\ \textgreater \
Find magnitude:
|F_1| =  \sqrt{((-4.646)^2+(11.135)^2} = 12.065
Do the same with 2nd ranger station:
F_2 = \ \textless \  7.5 cos(20) + 5.3 cos(100), 7.5 sin(20) + 5.3 sin(100)\ \textgreater \
F_2 = \ \textless \ 6.127, 7.784\ \textgreater \
|F_2| = \sqrt{(6.127)^2 + (7.784)^2}  = 9.9

Therefore the 2nd ranger station is closest to starting point.

Find the simplified product:<img src="https://tex.z-dn.net/?f=%5Csqrt%7B2x%5E%7B3%7D%20%7D-%5Csqrt%7B18x%5E%7B5%7D%20%7D" id="Te

Correct Question: Find the simplified product: \sqrt{2x^3}*\sqrt{18x^5}

Answer:

6x^4

Step-by-step explanation:

Based on the rules of radicals, since \sqrt{2x^3} and \sqrt{18x^5} has the same index (square root), therefore:

\sqrt{2x^3}*\sqrt{18x^5} = \sqrt{2x^3 * 18x^5}

To simplify this, multiply their bases together, and add their exponents.

= \sqrt{2*18x^{3+5}

= \sqrt{36x^{8}

Simplify further

= \sqrt{36}*\sqrt{x^8}

= \sqrt{6*6}*\sqrt{x^4*x^4}

= 6x^4

What is the answer to the problem i need help with?
AveGali [126]

Answer:

C

Step-by-step explanation:

Recall the equation for a circle:

(x-h)^2+(y-k)^2=r^2, where the center is (h,k) and the radius is r.

The given equation is:

(x+5)^2+(y+7)^2=21^2

Another way to write this is:

(x-(-5))^2+(y-(-7))^2=21^2

Thus, we can see that h=-5 and k=-7.

The center is at (-5, -7).
