Set the function equal to 0 and solve for
x= 3,2 + i, 2 −i
Answer:
r = 22 ft the sprinkler sends water until 22 feet away
Step-by-step explanation:
A circular pattern has an area of 1,519,76 ft²
And the areaof a circle is:
A(c) = π*r²
A(c) = 3,14 * r² ⇒ 1,519,76 = 3,14 * r²
r² = 1,519,76/3,14 ⇒ r² = 484
r = √484
r = 22 ft
Answer:
X=18
Step-by-step explanation:
Answer:
x = 15
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
BC/DC = EC/AC , substitute values
3x×5/32 - 5x-5/56 ( cross- multiply )
56(3x - 5) = 32(5x - 5) ← distribute and simplify both sides
168x - 280 = 160x - 160 ( subtract 160x from both sides )
8x - 280 = - 160 ( add 280 to both sides )
8x = 120 ( divide both sides by 8 )
x = 15
Answer:
x = - 1
Step-by-step explanation:
Given
9 = - x + 8 ( subtract 8 from both sides )
1 = - x ( multiply both sides by - 1 )
- 1 = x ⇒ x = - 1
