Area = π r^2
π = 3.14
r = 2.2
Area = 3.14 * 2.2^2
Area = 3.14 * 4.84
Area = 15.1976 You should round this somewhere. Perhaps 15.2 is the better answer rounded.
15.2 <<<< answer.
Answer:
The logarithmic function modeled by the given table:
f(x) = log₃x
Step-by-step explanation:
Given Table:
x f(x)
9 2
27 3
81 4
We can see that x increases as powers of 3. And f(x) is the power.
We assume that f(x) = log₃x
Checking using the table:
for x = 9
f(x) = log₃9 = 2
for x = 27
f(x) = log₃27 = 3
for x = 81
f(x) = log₃81 = 4
Hence proved.
Answer:
Step-by-step explanation:
A: x = 12-4 = 8
B: x = 12/4 = 3
No wonder you asked for help. Some of the questions don't make sense!
x+3 = 9 ⇒ x=6, which doesn't match either A or B.
3·x = 9 ⇒ x=3, which matches B
9 = 3·x is the same as the previous equation, i.e., B.
3+x = 9, doesn't match either A or B.
x = 9-3, doesn't match either A or B
x = 9÷3 ⇒ x=3, which matches B
x+x+x = 9 ⇒ x=3, which matches B
I'm guessing that there is an error in tape A, and x should be 6, not 8.
Answer:
If we add up all the angles of any triangle, we should get 180 degrees. Therefore, Angle C = 90 (angle A) - 45 (angle B) = 45 degrees. Since there was a ray drawn from A through C the exterior angle of angle C is angle 1.
Step-by-step explanation:
a "one angle" A degree (in full, a degree of arc, arc degree, or arcdegree), usually denoted by ° (the degree symbol), is a measurement of a plane angle in which one full rotation is 360 degrees. ... Because a full rotation equals 2π radians, one degree is equivalent to π180 radians.
