The sweaters sale price would be 20. Since the sweater normally cost $50, and it’s 30% , it’s taking 30 away from the 50 which is : 50-30= 20
Answer:
The answer is (-5,-2)
Step-by-step explanation:
Yes.
A bisector of a line segment is a line which divides the line segment into two equal parts.
A bisector of a line can divide the line in many different ways forming different angles.
A bisector is said to be a perpendicular bisector if the angle at the intersection of the two lines is 90 degrees.
But, there are several other bisectors that are not perpendicular bisectors.
Therefore, <span>it is possible for a segment to have more than one bisector.</span>
Answer:
children = 172 adults = 190
Step-by-step explanation:
x= 172 y=190
1.5x+4y = 1018
x+y=362
4x+4y=1448
-1.5x-4y=-1018
2.5x=430
x=172
1.5(172) + 4y =1018
258 + 4y = 1018
4y = 760
y = 190
The maximum height is 9.0 feet and the time to hit the ground is 4.5 seconds
<h3>How to determine the maximum height?</h3>
The function is given as:
f(x) = -0.6x^2 + 2.7x + 6
Differentiate
f'(x) = -1.2x + 2.7
Set to 0
-1.2x + 2.7 = 0
Subtract 2.7 from both sides
-1.2x = -2.7
Divide both sides by -1.2
x = 2.25
Substitute x = 2.25 in f(x) = -0.6x^2 + 2.7x + 6
f(2.25) = -0.6(2.25)^2 + 2.7(2.25) + 6
Evaluate
f(2.25) = 9.0
Hence, the maximum height is 9.0 feet
<h3>How to determine the time to hit the ground?</h3>
The time to hit the ground is twice the time to reach the maximum height.
In (a), we have:
x = 2.25
So, we have:
Time = 2 * 2.25
Evaluate
Time = 4.5
Hence, the time to hit the ground is 4.5 seconds
