Trinomial is the ancer to the first one
Answer:
This is the answer , P = 1 + (1/10)x
Step-by-step explanation:
We have,
At sea level pressure is 1 Atmosphere (i.e at x =0, P0=1 atmosphere)
At depth 23 meters , pressure = 3.3 Atmosphere
Since the pressure increases at constant rate as the depth increases, So we can write a relation as:
P =P0 + kx , where P is the pressure , P0 is the initial pressure, x is the depth and k is constant rate of increasing.
To find constant rate k, Plug P = 3.3 , P0 = 1 and x= 23 meters
We get,
3.3 = 1 + k * 23
k = 2.3 / 23 = 1/10
So we can write the function formula as: P = 1 + (1/10)x
Answer:
133.2
Step-by-step explanation:
First take off the 40%
740 - (40/100)*740
740 - 0.4 * 740
740 - 296
444
=========================
That answer of 444 is the new selling price.
Now you take 30% of 444
30% of 444
30/100 * 444
0.3 * 444
133.2
Joseph will have to pay 133.2 dollars for the TV he want.
===========================
One Step
===========================
You could do this problem all in one step
30% (740*60% )
0.3 ( 740*0.6)
0.3(444)
133.2
=================
Both methods give the same answer.
You don't need expedite and you don't need urgency.
All you need is the formula for the volume of a sphere.
==> Volume of a sphere = (4/3) (pi) (radius)³ .
The question gave you the radius, and told you what to use
for 'pi', so now you have all the information you need.
The easiest way to do it would to be move the decimal to the right two places. so then it would be 40%. another way you can do it is to times it by 100
