Answer:

- 7, - 3, 1, 5

Step-by-step explanation:

Using the recursive rule and a₁ = - 7, then

a₂ = a₁ + 4 = - 7 + 4 = - 3

a₃ = a₂ + 4 = - 3 + 4 = 1

a₄ = a₃ + 4 = 1 + 4 = 5

The first four terms are - 7, - 3, 1, 5

What is the probability of rolling a summer five when rolling to six sided number cubes

Vera_Pavlovna [14]

Not sure about the summer part, but the answer should be 1 / 6. Maybe your question is wrong.

A ball is launched straight up in the air from a height of 6 feet. Its velocity (feet/second) t seconds after launch is given by

german

Step-by-step explanation:

A ball is launched straight up in the air from a height of 6 feet. The velocity as a function of time t is given by :

f(t) = -32 t+285

Height of the ball is :

$h(t)=\int\limits{f(t){\cdot} dt}\\\\h(t)=\int\limits{(-32t+285){\cdot} dt}\\\\h(t)=-16t^2+285t+C$

C is constant. Here the ball is launched from a height of 6 feet. So,

$h(t)=-16t^2+285t+6$

At t = 2 s, $h(t)=-16(2)^2+285(2)+6=512\ m$

At t = 9 s, $h(t)=-16(9)^2+285(9)+6=1275\ m$

Between 2 s and 9 s, the ball's height changed is : 1275 - 512 = 763 m.

C2d3 has a solubility product constant of 9.14×10−9. what is the molar solubility of c2d3?

UkoKoshka [18]

The correct answer for the question that is being presented above is this one:

We need to express the ksp expression of C2D3
C2D3
= (2x)2(3x)3
= 108x5 

Then set that equation equal to your solubility constant 

9.14x10-9 = 108x5 
x = 9.67x10-3

So the molar solubility is 9.67x10-3
