Answer:
See below description.
Step-by-step explanation:
The function 
has the following characteristics:
- Factors:
- Zeros/roots: x=0, x=-2, amd x=1
- Positive leading coefficient
- Graph starts up, curves down through -2 on the x-axis and back up to 0 where it touches and curves down and back up again again. It comes down back through 1 and crosses.
- Its graph s the shape of a W.
- It has minimum values at -2.83 and -0.397
Answer:
3. A=B=70°; C=D=110°
4. A=90°; C=48°
Step-by-step explanation:
Same-side angles of a trapezoid add to 180°.
___
3. (2x) +(x+15) = 180
3x + 15 = 180 . . . . simplify
x +5 = 60 . . . . . . . divide by 3
x = 55
A=B=(x+15)° = (55+15)° = 70°
C=D=2x° = 2·55° = 110°
__
4. You are given the values of one of the angles on each side, so the other can be found by subtraction:
A=180°-D = 90°
C = 180° -132° = 48°
Answer:
y = 6
Step-by-step explanation:
Given that y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 3 when x = 9, then
k = 
= 
= 
, thus
y = x ← equation of variation
When x = 18, then
y = × 18 = 
= 6
Answer:
The estimated weight is in the range:
75.6 pounds 
Weight 92.4 pounds
Step-by-step explanation:
Since, the maximum error is 10%.
Therefore, the maximum and minimum vales will be 10% more and 10% less than 84 pounds, respectively.
<u>For Maximum Limit</u>:
= (1.1)(84 pounds)
= <u>92.4 pounds</u>
<u>For Minimum Limit</u>:
= (0.9)(84 pounds)
= <u>75.6 pounds</u>
Hence, the estimated weight is in the range:
75.6 pounds Weight 92.4 pounds
