1 answer:

3 0

[email protected] = 52,000,000
[email protected] = 55,000,000
[email protected] = ?
r = ?

Equation: P = Po * e^(rt)
-----
Solve r:
P/Po = e^(rt)

ln(P/Po) = rt
r = ln(P/Po)/t
r = ln([email protected]/[email protected])/(2000-1994)
r = ln(55M/52M)/6
r = 0.009348

----
Solve for [email protected]
t = 2003 - 1994 = 9

[email protected] = [email protected] * e^(rt)
[email protected] = 52M * e^(0.009348*9)
[email protected] = 56,564,292.9

approximately 57M.

an aircraft carrier leads port heading due west at 28 knots. A helicopter is 175 nautical miles from the carrier at an angle of

emmainna [20.7K]

Let’s say it takes time t hours for the interception.
In that time the carrier travels 28t nm west and the helicopter 130t nm.
Now we use the sine rule to find the angle x which lies between the distance 175 and 130t.
sin(x)/28t=sin35/130t. So sin(x)=28sin35/130=14sin35/65=0.1235 and x=7.0964 degrees.
Therefore the helicopter should use a bearing of 35+7.0964=42.0964 degrees north of east or 47.9 degrees east of north approx.

PLZZZ HELP XD WILL GIVE BRAINLIEST WHERE TO PUT THE POINT ON THE NUMBER LINE!!!!!

lana66690 [7]

Every number has its purpose in this case you start at -3 then the negative sign tells you which way you are going but since we have another negative sign in between the number we go to the right instead of left with that said you put the point in number 4

How do I find out if a function is in standard form

anzhelika [568]

Hey!

A function in slope-intercept form would look like y=mx+b; with the x and y values on the opposites of the equation.

A function in standard form would look like ax+by=c; with the x and y values on the same side of the equation.

Hope this helps!

This question is not correctly written

Correct question

Noah drank 4/5 liter of water Monday before going jogging. He drank 2/3 liter of water after his jog. How much water did Noah drink altogether? Write your answer as a mixed number.

Answer:

$1\frac{7}{15}$

Step-by-step explanation:

Noah drank 4/5 liter of water Monday before going jogging. He drank 2/3 liter of water after his jog.

To find the total liters of water he drank, we should add up the liter of water he drank on Monday before going jogging and liter of water after his jog.

4/5 + 2/3

Find the Lowest Common Multiple for 5 and 3 , which is 15.

= [(4×3) + (2×5)] /15

= 12 + 10/ 15

= 22/15

As a mixed Fraction, the answer

= $1\frac{7}{15}$
