Answer:
x = 1 + i, x = 1 - i
Step-by-step explanation:
Make the second equation y = 3x - 1
Substitute: 3x - 1 = 1/2x^2 + 2x
Simplify: 6x - 2 = x^2 + 4x
x^2 + 4x + 2 = 6x
x^2 - 2x + 2 = 0
Complete the square: x^2 - 2x + 1 = - 1
(x - 1)^2 = -1
x - 1 = ± √-1
Take out the negative: x - 1 = ± i
x = 1 + i, x = 1 - i
i is for imaginary number

A tree cast a 30 1/2 ft shadow at the time of day when a 2ft stake casts a 7 2/3 ft shadow.Estimate the height of the tree.
Answers
Answer:
The tree is about 8 feet.
Step-by-step explanation:
7 2/3 = 7.6 as a fraction.
30 1/5 = 30.5 as a fraction.
Know, we must divide 30.5 by 7.6.
30.5 ÷ 7.6 = 4 when rounded to the nearest whole number.
Since we know that the stake is 2 feet, we must multiply this by 4, since the other shadow is 4 times the amount of the stake.
2 x 4 = 8
This means the tree is about 8 feet.
A square tile measures 16 inches on each side. If 1 inch = 2.54 centimeters, determine the area of the tile in square centimeters. Round the answer to the nearest square centimeter.
650 cm2
41 cm2
1,652 cm2
256 cm2
Answers
The answer to the nearest square centimeters is 1,652 cm2.
The calculation can be calculated as follows :
The first step is to convert the tile measures in inches to centimeters.
1 inch = 2.54 centimeters
16 inches = 16 x 2.54 centimeters
16 inches = 40.64 centimeters
The second step is to calculate the area of the tile in square centimeters.
Tile's area in square centimeters
= 40.64 x 40.64
= 1,651.6096 cm2
The last step is to round the answer to the nearest square centimeters.
= 1,651.6096 cm2
= 1,652 cm2
Hence, the area of the tile in square centimeters is 1,652 cm2.

area of triangle=15*square root of 5
Step-by-step explanation:
Answer:
a. 7.4 cm
b. 22.2 cm²
Step-by-step explanation:
a. Apply Pythagorean theorem to find h.
c² = a² + b²
Where,
c = 8 cm
a = 3 cm
b = h cm = ?
Plug in the values
8² = 3² + h²
64 = 9 + h²
64 - 9 = h²
55 = h²
h = √55
h ≈ 7.4 cm
b. Area of the triangle = ½*bh
b = 6 cm
h = 7.4 cm
Area = ½*6*7.4
Area = 22.2 cm²

Question 13 of 15
A canoe travels 6 miles per hour downstream and 2 miles per hour upstream.
Let x represent the canoe's speed with no water current (still water) and y
represent the speed of the water current, in miles per hour. Then the situation
can be represented by this system of equations:
Choose the two correct options.
x + y = 6
x - y = 2
A. The speed of the canoe in still water is 4 miles per hour.
B. The speed of the canoe in still water is 2 miles per hour.
C. The speed of the water current is 4 miles per hour.
D. The speed of the water current is 2 miles per hour.
Answers
ANSWER : A AND D.
Step-by-step explanation:
the water current would be 2 mph and the canoe is 4 mph
See, 6miles downstream it would be 4mph of canoe + water boost ( 2 mph) = 6mph.
The canoe upstream would be 4mph - water resistance (2mph) = 2mph upstream.
The answers should be A and D.

Since events A and B occur independently, it means that if A occurs, B May or May Not occur, vice versa. (basically, event A and B can occur on its own or together which are not dependent on the other event)
For probability of A and B to occur, and that probability of A / Probability of B occurring are not dependent on each other at any circumstance, u need to multiply the P(A) and P(B) to find out the chances of A and B occurring.

the volume of the right circular cylinder in 144π cubic yards. if h, the height of the cylinder is 4 yards, what is r, the radius of the base?
Answers
If the volume of the cylinder is 144π cubic yards and the height of the cylinder is 4 yards, you can set up the equation:
144π = πr^2 * 4
You can then solve for r by dividing both sides of the equation by 4π:
r^2 = 36
r = 6
Thus, the radius of the base of the cylinder is 6 yards.
Answer:
r = 6
Step-by-step explanation:
The formula for the volume of a cylinder is V = πr^2h,
If the volume of the cylinder is 144π cubic yards and the height of the cylinder is 4 yards it can be written as 144π = πr^2 * 4
You can then solve for r by dividing both sides of the equation by 4π:
r^2 = 36
r = 6
