Step-by-step explanation:
We are given a few functions in options and we have to choose from them that has the domain [a,∞) and range (-∞,b].
Now, for domain i.e. the value of x ≥ a.
Therefore, the value of y must be a function of
So, there is only one function ............ (1), that has the term in it.
Now, for x = a, the value of f(x) becomes b and for x = ∞ the function f(x) value becomes -∞.
Therefore, the range of the function will be (-∞,b] i.e. y ≤ b.
Hence, the required function is . (Answer)
Answer:
tan theta = 2 sqrt(5) /15
Step-by-step explanation:
sin theta = opp / hypotenuse
sin theta = 2/7
We can use the Pythagorean theorem to find the length of the adjacent side
a^2 + b^2 = c^2
2^2 +adj^2 = 7^2
4 + adj^2 = 49
adj ^2 = 49-4
adj^2 = 45
Taking the square root of each side
adj = sqrt(45) = sqrt(9*5) =sqrt(9) sqrt(5) = 3 sqrt(5)
The tan theta = opp/ adj
tan theta = 2 / 3 sqrt(5)
Multiply by sqrt(5) / sqrt(5)
= 2 sqrt(5) / 3 *5
= 2 sqrt(5) /15
Answer:
x=-4 , y=1
Step-by-step explanation:
-x+y=5
x-5y=-9
Add the two equations together to eliminate x
-x+y=5
x-5y=-9
-------------------
-4y = -4
Divide each side by -4
-4y/-4 = -4/-4
y = 1
Now we need to find x
x-5y=-9
x -5(1) = -9
x -5 =-9
Add 5 to each side
x-5+5 =-9+5
x = -4
Answer:
68
Step-by-step explanation:
Find the vanilla first by dividing 420 by 7 and multiplying the quotient by 2 to get 120.
Then find the banana using the equation 35/100 = x/420, cross multiply to get 147.
Add 120 and 147 to get 267.
Subtract 267 from 420 to get 153.
Divide 153 by 9 to get 17.
Get the number of lemon cakes by multiplying 17 by 4.
The number of lemon cakes is 68!
(and chocolate cakes is 85)
