Increased price = $10 + $10×15% = $11.50
decreased price = $11.50 - $11.5×25% = 8.625
The vertex is at (0, 3) so y=a(x-0)²+3, which is y=ax²+3
next, use a given point to find a: 10=a(3)²+3, so 9a=7, a=7/9
the equation is then y=
as for the first question, the shape is an ellipse, the domain is -5≤x≤5, the range is -3≤y≤3
the equation can be written as :
Answer:
D
x-intercepts = (-,0), (,0)
y-intercept = (0,3)
Answer:
B
Step-by-step explanation:
i took the same question hope this helps :D
Step 1
find the total volume of the fish tank
volume of a rectangular prism=51*39*28----> 55692 cm³
step 2
find the 95% of the volume of the tank fish
95%=55692 cm³*.95-----> 52907.40 cm³
step 3
find the 5% of the volume of the tank fish
5%=55692*0.05----> 2784.6 cm³
or
55692-52907.4=2784.6 cm³
step 4
find the volume of the log
volume of a cylinder=pi*r²*h
r=5 cm
h=44 cm
volume of a cylinder=pi*5²*44-----> 3454 cm³
step 5
<span>water spills out of the tank=volume of the log-volume of the 5% of the tank
</span>water spills out of the tank=3454 cm³-2784.6 cm³-----> 669.40 cm³
the answer is
669.40 cm³
