Given the vertex of (3, 6) of a quadratic and a point at (4,8) what would be the a value for the quadratic?

svetoff [14.1K]

Answer:

a = 2

Step-by-step explanation:

The vertex form y = a(x - h)^2 + k

Where (h, k) is the vertex.

Given: (h, k) = (3, 6) and point (4, 8)

Now plug in the given values and find the value of "a"

x =4 and y = 8

8 = a(4 - 3)^2 + 6

8 = a(1)^2 + 6

8 = a + 6

a = 8 - 6

a = 2

So the value of a = 2.

Hope you will understand the concept.

Thank you.

What are the relative frequencies, to the nearest hundredth, of the rows of the two-way table?

sveta [45]

Answer: A B

Group 1 0.25 0.75

Group 2 0.44 0.56

Step-by-step explanation:

Since we have given that

Number of people of A in group 1 = 15

Number of people of B in group 1 = 45

Total number of people in group 1 is given by

$15+45=60$

Relative frequency of people of A in Group 1 is given by

$\frac{15}{60}=0.25$

Relative frequency of people of B in Group 1 is given by

$\frac{45}{60}=0.75$

Similarly, Number of people of A in group 2 = 20

Number of people of B in group 2 = 25

Total number of people in group 2 is given by

$20+25=45$

Relative frequency of people of A in Group 2 is given by

$\frac{20}{45}=0.44$

Relative frequency of people of B in Group 2 is given by

$\frac{25}{45}=0.56$

Hence, A B

Group 1 0.25 0.75

Group 2 0.44 0.56
