Answer:
therefore y= - (x-2)^2 + 5
Step-by-step explanation:
u do this by using this format here ..,
y=a(x-h)^2+k
sub in the vertex points as h=2 and k = 5 , since the 2 is positive its sign will be -2 in the brackets because when solving for x-2=0 it is x=2
y=a(x-2)^2+5
then with your (0,1) points plug that in as y and x
1=a(0-2)^2+5
1=a(-2)^2+5
1=4a+5
1-5=4a
-4=4a
a=-1
therefore y= - (x-2)^2 + 5
Answer:
3
Step-by-step explanation:
Cube root of 27 is 3.
3³ = 27.
Given:
Length = 20 cm
Width = 4.5 cm
Height = 23 cm
To find:
Surface area of rectangular prism
Solution:
Surface area formula:
SA = length × width × height
= 20 × 4.5 × 23
= 2070
Surface area of cylinder is 2070 square centimeters.
First time he picks a marker there is a 3/8 chance because 3 markers out of all the markers.
second time there is a 2/7 chance because there are only 7 markers left and 2 markers of those are red
so it would be 3/8 times 2/7 or about .107
