PETS Last month, Hao's dog ate 40 cans

HELP ASAP PLEASEEEEEE

Archy [21]

Answer:

2a-6=a

Step-by-step explanation:

The keyword "times" lets us know we need to multiply 2 and a and "less" shows us we need to subtract 6 from that.

What would be the equation of the cannonball’s path if it was launched with the same velocity, but from the ground instead?

natita [175]

The quadratic equation cannonball’s path if it was launched with the same velocity, but from the ground instead would be given by:

$h(t) = -4.9t^2 + 19.8t$

<h3>What is the quadratic equation for the height of a projectile?</h3>

Considering the gravity, it is modeled by:

$h(t) = -4.9t^2 + v_0t + h_0$

In which:

$v_0$ is the initial velocity.

$h_0$ is the initial height.

For this problem, we want:

The same initial velocity, hence $v_0 = 19.8$ .

Launched from the ground, hence $h_0 = 0$ .

Then, the equation is:

$h(t) = -4.9t^2 + 19.8t$

Brady creates the graph below to keep track of the approximate height of the grass on his

IgorC [24]

Answer:

<h2>Time is the independent variable and Height of the Grass is the dependent variable.</h2>

Step-by-step explanation:

The graph is about the height of the grass thourgh time, that means Brady is analysing how long it takes to the grass to grow.

It's important to know that time is a variable which doesn't depends on any other variabel, that is, it's an independent variable all the time.

Therefore, Time is the independent variable and Height of the Grass is the dependent variable.

This is just simple deduction, because the grass grows through time, it doesn't happen in the opposite way, time doesn't change accoring to the height of the grass.

What is the slope of the line through (-9,6)(âˆ’9,6)(, minus, 9, comma, 6, )and (-3,9)(âˆ’3,9)(, minus, 3, comma, 9, )?

Diano4ka-milaya [45]

Answer:

0.5

Step-by-step explanation:

The slope m of a linear equation y = mx + b that goes through point (-9,6) and point (-3, 9) would have the following formula

$m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{9 - 6}{-3 - (-9)} = \frac{3}{6}= \frac{1}{2}$ or 0.5

Where $(x_1,y_1), (x_2, y_2)$ are the coordinates of the 2 points that this line goes through

Determine the first four terms of the sequence in which the nth term is

Licemer1 [7]

<u>Answer:</u>

The correct answer option is: $\frac{1}{3} ,\frac{1}{4} ,\frac{1}{5} ,\frac{1}{6}$ .

<u>Step-by-step explanation:</u>

We know that the $nth$ term $a_n$ for an arithmetic sequence is given by:

$a_n=\frac{(n+1)!}{(n+2)!}$

where $n$ is the number of the position of the term.

We are supposed to find the first four terms of the sequence so we will substitute the values of $n$ from 1 to 4 in the given formula to get:

1st term:

$a_1=\frac{(1+1)!}{(1+2)!}=\frac{1}{3}$

2nd term:

$a_2=\frac{(2+1)!}{(2+2)!}=\frac{1}{4}$

3rd term:

$a_3=\frac{(3+1)!}{(3+2)!}=\frac{1}{5}$

4th term:

$a_4=\frac{(4+1)!}{(4+2)!}=\frac{1}{6}$
