Answer:
Tan30° = 4/y
Tan30° = 1/root3
Therefore 4/y = 1/root3
Which gives the value of y 4root3
Which is 6.92 (approx)
As for x
Sin30 =4/x
1/2=4/x
X=8
The domain<span> of a function is the complete set of possible values of the independent variable. In plain English, this definition means: The </span>domain<span> is the set of all possible x-values which will make the function "work", and will output real y-values.
so the given is already the domain
</span><span>x is less than or equal to 1</span>
Answer:
56
Step-by-step explanation:
a + 89 + b
Let a= 12 and b = -45
12 + 89 - 45
101-45
56
Answer:
Step-by-step explanation:
area = length x breadth
length = 5 inches greater than width = 5+x
width = x
area = (5+x) x
104 = (5+x) x
104 = 5x + x²
x²+5x-104 =0
looking for two numbers that when you multiply gives 104, and adding it gives +5
the numbers is 13 and 8 (-13, +5)
x²+5x-13x-104 =0
x(x+5)-13(x+5) = 0
(x+5)(x-13)=0
x+5 =0 x-13 =0
x = -5, x=13
x= -5, 13
the width is either -5 or 13 inches
the length = (5+x) = (5+(-5)) = 5-5 =0
(5+x) = (5+13) = 5+13 = 18
lenth is 0 or 18 inches
