Answer:
g(x) = 7√x
Step-by-step explanation:
Parent function: f(x) = √x
Parent function vertically stretched by a factor of 7: g(x) = 7√x
Answer:
110.1°
Step-by-step explanation:
Use the inverse cosine function (arccos or cos⁻¹).
... cos(θ) = -0.344
... θ = arccos(-0.344) = 110.1°
_____
The range of the arcos( ) function is 0 – 180°, so no adjustment of the angle is necessary. (Make sure your calculator is in <em>degrees</em> mode.)
Answer:
G. 14:5 is the correct answer.
Step-by-step explanation:
a:b = 4:5
a:c = 2:7
so,
here in first ratio a = 4
in second ratio a = 2
making them equal:
Taking LCM of 2 and 4 = 4
so
a:c = 2/7 = (2×2)/(7×2) = 4/14
so,
a = 4
c = 14
b = 5
so ratio c : b = 14:5
Answer:
68.54
Step-by-step explanation:
x=12
