We notice that for x = 2 , or x = 4, the value of y=0 (x intercept),
replace x by any of the latter value in y=a(x-3)² -1
===> 0= a( 2-1)² - 1====>a=1
Answer:
0.714
Step-by-step explanation:
Argument
The total number of cards = 5 yellow. 3 blue and 7 red = 15 cards in all.
The probability of choosing a yellow card first is 5/15 = 1/3.
We are now down to 14 cards
There are 3 blue cards.
P(yellow then blue) = 1/3 * 3/14
P(yellow then blue) = 1/14 = 0.0714
One way in which to do this problem is to find the inverse function of G(x) first. Another, faster, method is to look at G(x) = 3x + 1. Find the x value for which y = 1:
1 = 3x + 1. Then x must equal 0. If (0, 1) satisfies G(x) = 3x + 1, then (1, 0) satisfies the inverse function of G(x) = 3x + 1.
Thus, the value of the inverse function with input 1 is 0.
Step 1: Replace "G(x)" with y.
Step 2: Solve the resulting equation for x.
Step 3: Replace x with y and y with x.
-1
Step 4: Replace this "y" with G (x).
Now replace "x" with "1".
Answer:
Area = (5 * 6.5)/2 =16.25 sq.yds
Step-by-step explanation:
The area of a triangle is given by half of the product of the base and the height.
Here
base = 5 yd
height = 6.5 yd
Area = (5 * 6.5)/2 =16.25 sq.yds
