The function shown is in the form y = x2 + k. Determine the value of k.
A) -1
B) 0
C) 1
D) - 1 /2

Answers

y = 1
x = 0
1 = 0(2)+k
K = 1
Answer is C) 1
k=1
Looking at the graph:
(x,y) = (-2,5)
y=x^2 + k
5=(-2)^2 + k
5=4+k
k=5-4
k=1
Again, looking at the graph:
(x,y)=(-3,10)

10=(-3)^2+k
10=9+k
k=10-9
k=1

probability that it is green or yellow.

Answers

Answer:

65/139 fraction form

0.47 decimal form

Answer:

Step-by-step explanation:

Total sample space , n (s) = 139

no of green candies , n (g) = 45

no. of yellow candies , n (y) = 20

Probability that is green or yellow is

P( g or y) = P(g) + P(y)

               = n(g) / n(s) + n (y) / n(s)

               = 45 / 139 + 20 / 139

Answer:

AD = 7

Step-by-step explanation:

Given that the two triangles are similar by the SSS (side side side) postulate, the triangles share the same ratios when it comes to their sides.

We know the values for lines DB, EB and CB, therefore we can solve for AB, and subtract DB to find AD

We can solve the problem by solving for x:
