We are asked in the problem to solve for x in the expression tan(x+π)+2sin(x+π) = 0. tan theta is equal to sin theta over cos theta. Hence, the expression results to tan (x+π) = sin (x+π) / cos (x+π) = -2sin (x+π). Thus, 1/cos (x+π) = -2. cos (x+π) = -1/2, cosine becomes negative in the third and fourth quadrants. cosine is 1/2 when the terminal angle is pi/3. x is equal to pi/3 then and 5 pi/6.
The distance between points M(6,16) and Z(-1,14) to the nearest tenth is 5.4 units.
The formula for calculating the distance between two points is expressed as:
Given the coordinates M(6,16) and Z(-1,14)
Substitute the given coordinates into the formula
Hence the distance between points M(6,16) and Z(-1,14) to the nearest tenth is 5.4 units.

8x+9y equals 10 is a variation in fact
Answer: 1430
Step-by-step explanation: x + y + z = 2680
x = 2z - 100
y = 3z + 80
x + y = 5z - 20
6z - 20 = 2680
z = 450
y = 1430
Solution:
x = 800, y = 1430, z = 450
Hey user!!
here's ur answer..
atq, A 1200 sq ft house is advertised for sale at a price of 96000.
we have to find the cost per sq ft.
area of the house is given = 1200ft²
and price = 96000
therefore cost per ft² = 96000/1200
= 80
Cheers!!
