The function is an increasing linear function
<h3>How to determine the function type?</h3>
The function is given as:
f(x) = 4.2x
The above function is a linear function, because linear functions are represented as:
f(x) = mx + b
Where m represents the slope.
A positive slope represents an increasing linear function.
By comparison;
m = 4.2
4.2 is positive
Hence, the function is an increasing linear function

Answer:
steps
Step-by-step explanation:
1 - sin²θ / (1 - cosθ) = 1 - (1 - cos²θ) /(1 - cosθ)
= 1 - (1 + cosθ)(1 - cosθ) /(1 - cosθ)
= 1 - (1 + cosθ)
= - cosθ
The width is 3 feet. If you set up your equation like so...
lwh = A
(4) (2) (w) = 24
Then proceed to divide 24 by 4 and 2.
(4) (2) (w) = 24
/4 /4
2w = 6
/2 /2
w = 3 feet
PH can be calculated using the following equation
pH = -log [H₃O⁺]
for apple juice the hydronium /hydrogen ion concentration is 0.0003
pH = -log (0.0003)
pH = 3.5
correct answer is C
For ammonia
pH = -log (3.1 x 10⁻⁹)
pH = 8.5
answer should be 8.5
P(400<x<450)
P( (400-400)/50 < Z< (450-400)/50)
P (0 <z< 1) = 0.8413 -0.500=0.3413 = 34.13%
