If it’s blank and just a negative sign the answer should be -1
Answer:
The dilation is an enlargement by 3
Step-by-step explanation:
I took geometry lasy yr
The surface area of a sphere is A = 4 π R² .
Sadly, the question doesn't give you 'R', so you have to
back it out of the circumference.
Circumference = π (diameter)
Divide each side by π : Diameter = circumference / π
Radius = 1/2 diameter: Radius = circumference / (2 π)
Area = 4 π R² =
4 π (circumference/2π)² =
4 π (circumference)² / 4 π²
Divide top and bottom by 4π : Area = (Circumference)² / π
Circumference = 37.68 units
Area = (37.68)² square units /π =
<em>451.93 square units</em>
Answer:
f(4) = -18
Step-by-step explanation:
f(x) = -5x + 2
f(4) = -5(4) + 2 = -20 + 2 = -18
Answer:
steps below
Step-by-step explanation:
cos 23° = 6/x
0.92 = 6/x
x = 6/0.92 = 6.52
