Answer:
180 degrees in radians is π
Step-by-step explanation:
0° = 0 radians
90°= π/2
180 °= π
270°= 3π/2
360° = 2π
and so on
All real numbers / all x
if you're asking for range as well then its -1<x<1
Answer:
The cost of one rose is $11., and the cost of one geranium is $5.
Step-by-step explanation:
The cost of one rose bush and one geranium can be determined by the use of simultaneous equation. Let the cost of a rose bush be represented by x, and the cost of one geranium by y.
So that,
13x + y = 148 .............. 1
9x + 14 y = 169 ............... 2
From eqaution 1,
y = 148 - 13x ............... 3
substitute the value of y in equation 2
9x + 14(148 - 13x) = 169
9x + 2072 - 182x = 169
2072 - 169 = 182x - 9x
1903 = 173x
x = 
= 11
x = 11
substitute the value of x in equation 3
y = 148 - 13x
= 148 - 13(11)
= 148 - 143
y = 5
x = 11, y = 5
Thus, the cost of one rose is $11., and the cost of one geranium is $5.
Answer:
-8
Step-by-step explanation:
1. x + 23 = 15
2. x + 23 = 15
-23 -23
3. x = -8
