Step-by-step explanation:

Answer:
8x(2x+3)-2(x+3)
step by-step explanation:
16x^2+22x+3
16*3=48
2 numbers which have a product of 48 and a sum of 22
=24 and -2
Rewrite the centre term as these two numbers, so
16x^2+24x-2x+3
Factorise each pair of terms.
8x(2x+3)-2(x+3)
Answer:
A. the times at which the golf ball is on the ground
Step-by-step explanation:
The expression of the function is
h(x)= -4x^2+36x
The roots can be seen in the image below
You have a formula which represents the height over time.
The roots of the equation indicate that the height is equal to zero
The correct option is
A. the times at which the golf ball is on the ground
The ball is in the ground at x= 0 and x = 9 seconds
Answer:
2
Step-by-step explanation:
Estimate 1 2/11 to 1.
Estimate 2.97 to 3.
3 - 1 = 2
Answer:
Value of a is 2
Step-by-step explanation:
Given the equation of the quadratic function represented by the graph is
. we have to find the value of a.
As seen in the figure, parabola cuts the graph at point (2,1) implies point (2,1) is one of the solution of the given quadratic equation i.e of given parabola.
∴ Point (2,1) satisfies the given equation.
Hence, we can find the value of a by putting the value of x and y, we get

⇒ 
Hence, the value of a is 2
