Answer:
The amount of Rita's pocket money left is Rs. 36.
Step-by-step explanation:
Pocket money that Rita had before = 144
Money spent for magazines = 52% of 144
=
= 0.52(144)
= 74.88
Money spent for movies = 23% of 144
=
= 0.23(144)
= 33.12
Money left with Rita = 144 - (74.88 + 33.12)
= 144 - 108
= 36
Hence, Rita left with Rs. 36.
Aliter:
Total money spent = (52 + 23)% = 75%
So, money left with Rita = 100 - 75 = 25%
25% of 144 = 0.25(144) = 36.
I maybe totally wrong but i want to say either A or C. A nonreal number is any number that when multiplied by itseld produces a negative number.
Answer:
Explanation:
<u>1. Assume she runs up to a point that is x miles to the east of the coral reef:</u>
- distance running =
- distance swimming =
<u>2. Times:</u>
time= distance / speed
- time running =
- time swimming =
<u>3. Total time</u>
- time running + time swimming:
<u>4. Minimize time</u>
The minimum time is when the derivative of the function of time is zero.
Find the derivative of T(x), using rule of the sum, the derivative of the sum is the sum of the derivatives, and the chain rule:
Solve for x:
<u>5. Distance the visitor should run to minimize the time</u>
Hence, the visitor should run miles.
Hello,
y=k(x+3/2)²-25/2
and -8=k*9/4-25/2==>9/4k=9/2==>k=9/2*4/9=2
y=2(x+3/2)²-25/2
x- intercepts:
y=0=2(x+3*2)²-25/2
==>(x+3/2)²=25/4
==>x=-3/2-5/2 or x=-3/2+5/2
==>x=-4 or x=1
(-4,0) and (1,0) are x intercepts
Answer no choice!
