V=hπr^2

(15π(3.5^2)ft^3)(55/100)(7.5gal/ft^3)≈2381.23 gal  (to nearest hundredth of a gallon)

Ronch [10]

Answer:

10.77

Step-by-step explanation:

by using Pythagoras theorem we can find the distance between the points,

so...

distance between the points, which is the hypotenuse will be xy

difference between the y coordinates will be dy

difference between the x coordinates will be dx

according to pythagoras theorem,

xy^{2} = dx^{2} +  dy^{2} \\xy^{2} = (-6-(-2))^{2} + (-5-5)^{2}\\xy^{2} =(-4)^{2} +(-10)^{2} \\xy^{2} =16+100\\xy^{2} =116\\xy =\sqrt{116} \\xy=10.77

Solve 2cos^2x + cosx − 1 = 0 for x over the interval [0, 2 π ).
alina1380 [7]
Let cos x = a, then
2a^2 + a - 1 = 0,
solving the quadratic equation, we have:
a = 0.5 or -1.

i.e. cos x = 0.5 or cos x = -1
for cos x = 0.5,
x = pi/3, 2pi - pi/3 = pi/3, 5pi/3

for cos x = -1,
x = pi

therefore, x = pi, pi/3, 5pi/3

One number is 13 more. if the sum of the two numbers is 15, find the two numbers
AlexFokin [52]
Let number be x and x+13
Then x+x+13=15 (A/q)
2x+13=15
2x=2
X=1
:. X+13= 14

What is the next three terms in sequence of 8, 20, 50
krek1111 [17]
This sequence is doubling the sequence and adding half.  When n is your number, you could find the next number in your sequence by plugging in the number:

2n+0.5n

To find the 4th term, we need to plug in 50.

2*50+0.5*50=125

Now, we need to find the 5th term, so we plug in 125.

2*125+0..5*125=312.5

To find the 6th term, we plug in 312.5.

2*312.5+0.5*312.5=781.25

So, the next 3 terms are 125, 312.5, and 781.25
