Answer:
35%
Step-by-step explanation:
the percent is given by the ratio 735 / 2100 = 7/20 = 0.35
which in percent form is 35%
Answer:
24 years
Step-by-step explanation:
We are told that the model of number of deers is;
y = 0.75x² + 10.5x + 1300
Where;
y represents number of deers
x represents number of years
Now, we want to find how many years it will take to get to 2000 deers.
Thus;
2000 = 0.75x² + 10.5x + 1300
0.75x² + 10.5x + 1300 - 2000 = 0
0.75x² + 10.5x - 700 = 0
Using quadratic formula, we have;
x = [-b ± √(b² - 4ac)]/2a
x = [-10.5 ± √(10.5²- (4*0.75*-700)]/(2*0.75)
x = [-10.5 ± √(110.25 + 2100)]/(1.5)
x = [-10.5 ± √2210.25]/(1.5)
x ≈ -38 or 24
Number of years can't be negative, so we will take the positive value.
So, x = 24 years

Step-by-step explanation:
Answer:
14). 2nd quadrant
15). 1st quadrant
Step-by-step explanation:
14).Coordinates of a point → J(-8, -12)
Coordinates of the new point J' after reflection of x-axis will follow the rule,
(x, y) → (x, -y)
Coordinates of J' → (-8, 12)
Therefore, point J' will lie in 2nd quadrant.
15). Coordinates of a point → W(-6, 7)
Rule for the rotation by 90°clockwise about the origin,
(x, y) → (y, -x)
Coordinates of point W → (-6, 7)
Following this rule,
W(-6, 7) → W'(7, 6)
Therefore, point W' will lie in the first quadrant.
