Answer:

well i think you distribute the 3 to the two and the q so you multiply 3 * 2 = 6

3 * q = 3q then you add 6 + 3q = 9q

Nina [5.8K]

Answer:

In year 2039 both the events will happen again.

Step-by-step explanation:

We are given the following in the question:

Family reunion:

Every 7 year

Update the family tree:

Every 6 years

1997 was the year when they had a family reunion as well as they updated their family tree.

We have to find the year in which both the events will occur together.

We find the lowest common multiple of 7 and 6.

$L.C.M(7,6) = 7\times 6 = 42$

Thus, after 42 years both the event will happen again.

Year:

$1997 + 42 = 2039$

Thus, in year 2039 both the events will happen again.

1-Suppose the path of a baseball follows the path graphed by the quadratic function ƒ(d) = –0.6d2 + 5.4d + 0.8 where d is the ho

jasenka [17]

Answer:

1. The correct option B.

2.The correct option A.

Step-by-step explanation:

The given function is

$f(d)=-0.6d^2+5.4d+0.8$

Where f(d) is the height of the ball at horizontal distance d.

Put f(d)=0, to find the distance where the ball touch the ground.

$0=-0.6d^2+5.4d+0.8$

Quadratic formula:

$d=\frac{-b\pm \sqrt{b^2-4ac}}{2a}$

Using the quadratic formula we get

$d=\frac{-5.4\pm \sqrt{(5.4)^2-4(-0.6)(0.8)}}{2(-0.6)}$

$d=-0.146,9.146$

Therefore the ball is in air between d=-0.146 to d=9.146.

The distance can not be negative, therefore the ball remains in the air between d=0 to d=9.146.

$9.146\approx 9.15$

Therefore the correct option is B.

The given equation is

$y=(x-1)^2+1$ .... (1)

The standard form of parabola is

$y=a(x-h)^2+h$ .... (2)

Where, a is constant and (h,k) is vertex.

On comparing (1) and (2), we get

$a=1$

$h=1$

$k=1$

Since the value of a is positive, therefore it is an upward parabola. The vertex of the parabola is (1,1).

Put x=0 in the given equation.

$y=(0-1)^2+1$

$y=1+1=2$

Therefore the y-intercept is (0,2) and option A is correct.
