An isosceles trapezoid ABCD with height 2 units has all its vertices on the parabola y=a(x+1)(x−5). What is the value of a, if p
True [87]

Answer:

the value of a, if points A and D belong to the x−axis and m∠BAD=60 degrees is 2/√3

Step-by-step explanation:

Trapezoid ABCD with height 2 unit contain Points A and D which may be A(-1,0) and D(5.0)

Vertex of parabola is the point where parabola crosses its axis

Let suppose A and D are two points then draw altitude on them CE where C is on AD

As height of altitude has been given that is 2 then

total angle = 180 degrees

m∠BAD=60 degrees

m∠CEA =180 - 60 -90

             = 30

then the value for  AE = 2/√3.

y=a(x+1)(x−5).

where  2/√3 is right of -1 and 2 unit above x-axis

The formula F=95(K−273.15)+32 converts a temperature from kelvin K to degrees Fahrenheit
DENIUS [597]

F=95(K−273.15)+32

Switch the equation so that F is on the right side:

95(K−273.15)+32 = F

Use the distributive property:

95K + 95(-273.15) + 32 = F

95K - 25949.25 + 32 = F

95K - 25917.25 = F

Add 25917.25 to both sides:

95K = 25917.25 + F

Divide each term by 95:

K = 25917.25 / 95 + F/95


K = (25917.25 + F) /95

A sludge pool is filled by two inlet pipes. One pipe can fill the pool in 10 days and the other pipe can fill it in 25 days. How
skad [1K]

9.28 days are taken to completely fill the pool

It is given that one pipe can fill the pool in 10 days

the other pipe can fill it in 25 days.

if no sewage is added, waste removal will empty the pool in 31 days.

The amount filled by pipe one in 1 day=1/10

The amount of pool filled by second pipe in 1 day=1/25

The waste removal pipe's work in 1 day= 1/31

Therefore, the work done together by all pipes in one day=1/10+1/25-1/31

= (775+310-250)/31*25*10=835/7750

Therefore, number of days taken to empty the pool= 7750/835=9.28 days

As half day cannot be counted, hence 9.28 days are taken to completely fill the pool

Disclaimer: The waste removal pipe has also been taken into consideration
