Answer:
When we know all 3 sides we use the law of cosines
a = 47
b = 11
c = 38
cos (A) = (b^2+c^2-a^2) / (2bc)
cos (A) = -0.7703349282
Angle A = 140.38
cos (B) = (a^2 + c^2 -b^2) / (2ac)
cos (B) = 0.9888017917
Angle B = 8.5826 degrees
cos (C) = (a^2 + b^2 -c^2) / 2ab
cos (C) = 0.8568665377
cos (C) = 31.033 degrees
Angle W would be the smallest angle so it equals
31.033 degrees or rounded to nearest tenth
31.03

Answer:
0.6772
Step-by-step explanation:
Use a z-score table.
P(-0.85 < z < 1.15) = P(z < 1.15) − P(z < -0.85)
P(-0.85 < z < 1.15) = 0.8749 − 0.1977
P(-0.85 < z < 1.15) = 0.6772
Answer:
A
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k) = (1, 0) , thus
y = a(x - 1)² + 0
To find a substitute the coordinates of the y- intercept (0, 1) into the equation
1 = a(- 1)² = a , thus
a = 1
y = (x - 1)² → A
Answer:
C
Step-by-step explanation:
Miami rainfall: 1.61 +2.24 +2.99 +3.15 +5.35 + 9.68 = 25.02
Tampa rainfall: 2.24 +2.8 +3.03 + 2.05 + 2.09 + 6.69 = 18.9
25.02 - 18.9 = 6.12
Miami gets more rainfall by 6.12 more inches
Have a great day! :)
