The length if the garden is 68m, here's my work.
hope this helps, please mark brainliest, I need one more to level up. :)
Answer:
y = (x+5)(x+2)(4x-3)
Step-by-step explanation:
This is almost correct but the problem is that the signs should be flipped...
Why? If we solve for x-5=0 the answer we would get is 5, but the graph shows -5 as its zero so that doesn't match
The revised version would be the opposite signs
y = (x+5)(x+2)(4x-3)
F ( x ) = x² ( x² - 4 x + 3 ) =
= x² ( x² - 3 x - x + 3 ) =
= x² ( x ( x - 3 ) - ( x - 3 ) ) =
= x² ( x - 3 ) ( x - 1 ) = 0
x² = 0 ⇒ x = 0
x - 3 = 0 ⇒ x = 3
x - 1 = 0 ⇒ x = 1
The zeroes of the function are: x = 0, x = 1 and x = 3.
Answer:
B ) The number 0 is a zero of multiplicity 2; the numbers 1 and 3 are zeroes of the multiplicity 1.
Answer:
Step-by-step explanation:
<u>Use the law of cosines:</u>
- cos C = (25² + 27² - 28²)/(2*25*27)
- cos C = 0.4222
- m∠C = arccos 0.4222
- m∠C = 65°
