to find this answer you will have to divide 0.2 into 3.4.
0.2 goes into 3.4 17 times
therefore, you answer is 17 glasses of water can be poured.
D. (f•g)(x) = fgx
f(x) = 3x^2
f=3x
(3x)(x+2)=3x^2 + 6x
Answer:
4.08 + 2 = 6.08 years
Step-by-step explanation:
we know that
Simple Interest(S.I.) = (P × R × T) ÷ 100
where, P = Principal = 750
R = Rate = 6%
T = unknown
⇒ S.I. = (750 × 6 × t)÷ 100
⇒ S.I. = 45t
Also, Amount = S.I + Principal
⇒ Amount = 750 + 45t
Now Formula for Compound Interest is:
where A = Amount
=1000
P = Principle
r = rate
t = total number of year
Here, P = 750 + 45t, r = 3.5% , and t = 2.
Putting all these values in above formula:
⇒
⇒ t = 4.08
Hence, total time required will be 2 + 4.08 = 6.08 years.
We assume the deformed rails follow a circular curver wherer=radius in metres
Step 1: Express H in terms of rUsing the intersection chord relation, we defineH=maximum height of rail above horizontalthenH(2r-H)=3500^2 => H^2 - 2rH + 3500^2 = 0solve for H H=r-sqrt(r^2-3500^2) =>H= r - sqrt(r^2-12250000) ............(1)
Let x=half of the angle subtended by the chord at the centre.then by the difference of arc and chord:2r(x-sin(x))=0.017 =>2rx-2r(sin(x))=0.017 =>2rx-7000=0.017 =>2rx=7000.017......................(2)together with the simple relation of chord and radius,r*sin(x)=3500 ....................(3)Solve (2) and (3) for r and x to getr=910451.67, x=0.003844256Substitute r in (1) to getH= r - sqrt(r^2-12250000)=910451.67-sqrt(910451.67^2-12250000)=6.7275m
