Anxiety can cause you to overthink what you already know which interns makes you think you don’t know it. Math is just formulas and arthritic and if anxiety has you doubting that you know how to solve a problem then you won’t remember how to solve it
Y=-5x-7. I'm almost certain but you never know
Answer:
Real numbers
Step-by-step explanation:
The place where you placed your mouse was correct!
Real Numbers definition: All the numbers that can be found on a number line. Real numbers can be large or small, positive or negative, decimals, fractions, etc!
I hope this helps! Good luck with what you're doing! .ω.
The point from a given height to the horizon form a line that is tangent to the curvature of the earth.
The angle of the sector from observation height to horizon point is:
cosa=r/(r+h), where h is the height above the surface of the earth and r is the radius of the earth...
a=arccost(r/(r+h))
And the arc length is just 2pra/360=pra/180
So the distance to the horizon along the curvature of the earth is:
(pr/180)arcos(r/(r+h))
And we have two of these arcs one from the periscope height to the horizon and one from the top of the ship to the horizon.
If we simplify the radius of the earth 3959mi you get
For the periscope:
(3959p/180)arcos(3959/(3959+h)) remember that 5 ft is 5/5280 mi
2.74 mi (to nearest hundredth of a mile)
And for the top of the ship:
3959p/180)arcos(3959/(3959+h)) where h is 50/5280
8.68 mi (to nearest hundredth of a mile)
So the total distance along the curvature of the earth between when the periscope can just see the top of the ship is:
2.74+8.68=11.42 miles
Answer:
Here is a similar question attached with.
Option (b) that is 2005 is the right choice.
Step-by-step explanation:
Given:
An equation in slope intercept form.
Where = number of years
Comparing from the standard slope intercept form.
y-intercept value
According to the question the predicted winning speed mph
Plugging the value of in slope intercept form, we will calculate the (number of years) and then we will add this with .
⇒
⇒
⇒
⇒
⇒
⇒
Finally the year would be
So in year 2005 the winning speed is predicted to be 7.16 mph.
