Answer:
21.99 units
164.93 units²
Step-by-step explanation:
given radius r = 15 units
angle of sector = 84°
Length of sector = x 2 x π x r
= x 2 x 3.14 x 15
= 21.99 units
Area of sector = x π x r²
= x 3.14 x 15²
= 164.93 units²
Answer:
y = -13x+26
Step-by-step explanation:
13x+y=26
y= -13x+26
Answer:
D.) 9√2
Step-by-step explanation:
a^2 + b^2 = c^2
x^2 + 8^2 = √226^2
x^2 + 64 = 226
x^2 = 226 - 64
x^2 = 162
√x^2 = √162
√162 = √81 • √2
√81 = 9
√2 = √2
9√2

Go back to your power laws.
When dividing exponents with like bases, you keep the base and subtract the exponents:
a^4 / a^11 = a^(4-11) = a^(-7)
