Median: The only median is the segment JG

Altitude: There are two altitudes. They are segment JG and KF

Angle Bisector: There is only one angle bisector and it is segment JG

--------------------------------------------------------------

Explanations:

The median is a segment that goes from a vertex to the midpoint of the opposite side. Only one segment fits this description and it is segment JG

An altitude is a segment that goes from a vertex to the opposite side, and it is perpendicular to the opposite side (perpendicular is shown with square angle markers). Two segments fit this description which are JG and KF. It is possible for a median to also be an altitude. In this case, triangle KJL is an isosceles triangle (KJ = JL)

Angle bisectors cut a given angle into two equal or congruent halves. The segment JG fits this description. It is possible for a segment to be a median, altitude, and angle bisector.

Side Note: the segment EL is neither a median, nor an altitude, nor an angle bisector.

The volume of a cylinder, V, in terms of radius, r,

Igoryamba

Answer:

See explanation

Step-by-step explanation:

Volume of a cylinder = πr²h

Solve for r

V = π * r² * h

r² = V/πh

Find the square root of both sides

r = √V/πh

If height = 6 meters and volume = 300 cubic meters. Find r

r = √V/πh

= √(300/3.14*6)

= √(300/18.84)

= √15.923566878980

r = 3.9904344223381

Approximately,

r = 4 meters

the gross earnings • group health insurance (assuming 15% of gross earnings) pension deduction (assuming 6.5% of gross earnings)

sveta [45]

Step-by-step explanation:

Calculate the gross earnings:

40*7.75 = 310.00

Health insurance deduction:

310.00*15/100 = 46.50

Pension deduction:

310.00*6.5/100 = 20.15

Total deductions:

55.00 + 15.50 + 21.25 + 46.50 + 20.15 = 158.40

Net pay:

310.00 - 158.40 = 151.60

A package of pencils cost $6.25 per set at an office supply store. Which equation can be used to determine the price, P, of n se

ladessa [460]

To solve, it would be 6.25n. That eliminates both 6n25 over P, P equals 6.25 over n, and n=6.25P, leaving P=6.25n as the answer.

Find the 57th derivative of y = cos(7x).

mel-nik [20]

y = cos(7x)

First derivative = -7sin(7x)

Second derivative = - (7^2)cos(7x)

3rd derivative = (7^3)sin(7x)

4th derivative = (7^4) cos(7x)

5th derivative = -(7^5) sin (7x)

6th derivative = -(7^6) cos(7x)

nth derivative ?

Analysis and conclusion

If n is multiple of 4 or a number before a multiple of 8 the sign is positive

If n is one or two numbers after a multiple of 4 the sign is negative.

7 is raised to exponent n

if n is odd the function is sin(7x), if n is even the function is cos(7x)

n = 57 => odd, and it is a number after 56 which is a multiple of 4 => negative sign

Therefore, the 57th derivative = - (7^57)sin(7x)
