we have that
(r, ∅)----------> (-7, 5 pi/3)
we know that
5 pi/3--------> 300°-----------> -60°
To convert polar cordinates in rectangular one with use the following formula:
x=r*cos ∅------> x=-7*cos -60°-------> x=-7*(1/2)------> x=-7/2
y=r*sin ∅-------> y=-7*sin -60-------> y=-7*(-√3)/2----> y=7√3/2
the answer is the option
D) ordered pair negative 7 divided by 2 comma 7 square root 3 divided by 2
The slope is (4,3). You look at the y intercept (where the y axis is crossed by the line) and simply count rise over run until you reach the next point. The next point from the y intercept (-2,0) is (2,3).
-2+4=2
0+3=3
And there you go. In fraction form it’s 4/3.
Hope this helped!
Answer:
yes you are right bro
you said your not good well you just solved a problem that i needed help with from one of my friend.
Step-by-step explanation:
Thank you for posting your question here at brainly. The probe's elevation relative to sea level after the first minute, the probe dropped 11 feet per minute, therefore, it dropped 11 feet in the first minute. I hope the answer helps you.
Answer:
19
Step-by-step explanation:
From the question we have been given this data
y=ax+b
a=−1.077
b=30.98
r2=0.744769
r=−0.863
Where
X = number of situps
Y = number of hours spent watching tv
We have x = 11
Inputting this into the formula we have
Y = (-1.077)(11) + 30.98
Y = −11.847 + 30.98
Y = 19.133
Which is approximately 19
Therefore we conclude that a person who watches TV for 11 hours can do 19 situps.
