Answer:
2+1 is 3
Step-by-step explanation:
just add one more
Since we don't have a figure we'll assume one of them is right and we're just being asked to check if they're the same number. I like writing polar coordinates with a P in front to remind me.
It's surely false if that's really a 3π/7; I'll guess that's a typo that's really 3π/4.
P(6√2, 7π/4) = ( 6√2 cos 7π/4, 6√2 sin 7π/4 )
P(-6√2, 3π/4) = ( -6√2 cos 3π/4, -6√2 sin 3π/4 )
That's true since when we add pi to an angle it negates both the sine and the cosine,
cos(7π/4) = cos(π + 3π/4) = -cos(3π/4)
sin(7π/4) = sin(π + 3π/4) = -sin(3π/4)
Answer: TRUE
Answer:
$420t
Step-by-step explanation:
Given data
Principal= $7000
Rate= 6%
Time= t years
The expression for the amount is
Simple interest= PRT/100
Sustitute
Simple interest= 7000*6*t/100
Simple interest= 42000t/100
Simple interest= 420t
Hence the amount after t years is $420t
So, values of x are: 
Step-by-step explanation:
We need to find the square root of 5x^2 = 300
Writing in mathematical form:
Divide both sides by 5
Taking square root on both sides
So, values of x are:

32000 and 500 , so the number 32000 has three 0 and 500 2 , so you can take off two 0 from 32000, which equals to 320 .You have to find a number that times 5 equals 320 or almost , the most approaching number is 6 , because 5 times 6 equals 30 , then you have to subtract, the result of the subtraction is 2 , 2 is less than 5 so we have to put a zero , so we got 20 , which number times 5 can give you 20 ? , 4 , so your answer is 64 .
