PLEASE HELP ME IDK WHAT TO DO (SAD YEEHAW)!!!!! describe the graph: f(x)= (3/4)^x +4
1 answer:
Answer:
See attached picture.
y-intercept at (0,5) and asymptote at y = 4.
Step-by-step explanation:
This graph has a base 3/4 that is less than 1. This means it will start high and end low.
It has also been shifted up 4 units by adding 4. This means the asymptote moves to from y = 0 to y =4. The y-intercept of the parent function will also move from (0,1) to (0,5).

Answer:
m∠A = 30°
m∠B = 80°
m∠C = 70°
Step-by-step explanation:
By applying cosine rule in the given triangle,
b² = a² + c² - 2ac[cos(∠B)]
From the given triangle,
a = 14 m
b = 28 m
c = 24 m
(28)² = (14)² + (24)² - 2(14)(24)cos(B)
784 = 196 + 576 - 672cos(∠B)
cos(∠B) = 0.1786
∠B =
∠B = 79.71°
∠B = 80°
By applying sine rule in the given triangle,
sinA = 0.491958
A = 29.47°
A ≈ 30°
By applying triangle sum theorem,
m∠A + m∠B + m∠C = 180°
30° + 80° + m∠C = 180°
m∠C = 70°
