P^2=mx/t-t^2x make x the subject

belka [17]

Answer:

$x=\frac{P^2t}{(m-t^3)}$

Step-by-step explanation:

$P^2=\frac{mx}{t} -t^2x\\\\P^2+t^2x=\frac{mx}{t}\\\\t(P^2+t^2x)=mx\\\\P^2t+t^3x=mx\\\\P^2t=mx -t^3x\\\\P^2t=x(m-t^3)\\\\\frac{P^2t}{(m-t^3)} =\frac{x(m-t^3)}{(m-t^3)} \\\\\frac{P^2t}{(m-t^3)}=x$

Please Help??

SOVA2 [1]

Well, if you notice, is just an arithmetic sequence, is adding 2 to get the next term.

so the last term is 21, so the one before that has to be 21-2 or 19, and the one before that 17 and the one before that 15.

15+17+19+21.

How do i solve this pls

miskamm [114]

First we would solve both x’s
3x^2 - 5x
But 3 has the thingy thing (forgot the name haha)
Which means you have to multiply it by itself that many times which would be
3x3=9
So now it would be
9x- 5x = 4x
Which leaves 7 and 4x

Now you may subtract those two

7-4x= 3x

The total surface area of a hemisphere is 45 <img src="https://tex.z-dn.net/?f=%5Cpi%5Cp" id="TexFormula1" title="\pi\p" alt=

rjkz [21]

Answer:

The volume of the hemisphere

V = 121.33086 cubic centimeter

Step-by-step explanation:

Step(i):-

Given that the total surface area of a hemisphere = 45π cm²

The total surface area of a hemisphere = 3π r²

Equating

3π r² = 45π

$r^{2} = \frac{45}{3} =15$

r = $\sqrt{15} = 3.87$

The radius of the sphere 'r' = 3.87

Step(ii):-

The volume of the hemisphere

$V = \frac{2}{3} \pi r^{3}$

$V = \frac{2}{3} \pi (3.87)^{3}$

we know that π = 3.14

$V = \frac{2}{3} (3.14) (3.87)^{3}$

V = 121.33086 cubic centimeter

14 3/5 write each fraction or mixed numbers as a decimal

garri49 [273]

Answer: 14.60

Step-by-step explanation:

we have

14 3/5

This is a mixed number

we know that

A mixed number is a combination of a whole number and a fraction.

14 3/5 is equal to

14+3/5

where

14 is the whole number

3/5 is the fraction

3/5 = 0.60

14 + 3/5 = 14 + 0.60

therefore

= 14.60

the answer is

14.60
