Which of these is a correct step in constructing congruent angles?

Which expression represents the correct form for the quotient and remainder, written as partial fractions, of

Oduvanchick [21]

Answer:

$C)~A+ \frac{B}{x-3} +\frac{c}{(x-3)^2}$

Step-by-step explanation:

→ $\frac{(7x^2-40x+52)}{(x^2-6x+9)}$

→ $\frac{7x^2-40x+52}{x^2-2.3x+(3)^2}$

→ $\frac{7x^2-40x+52}{(x-3)^2}$

So, your answer is C

If a cannonball is shot directly upward with a velocity of 160 ft per second, its height above the ground after t seconds is gi

Contact [7]

Step-by-step explanation:

If a cannonball is shot directly upward with a velocity of 160 ft per second. Its height as a function of time is given by :

$h(t)=160t-16t^2$ .......(1)

t is in seconds

(a) Velocity is given by :

$v=\dfrac{dh}{dt}\\\\v=\dfrac{d(160t-16t^2)}{dt}\\\\v=(160-32t)\ ft/s$

Acceleration is given by :

$a=\dfrac{dv}{dt}\\\\a=\dfrac{d(160-32t)}{dt}\\\\a=-32\ ft/s^2$

(b) For maximum height put $\dfrac{dh}{dt}=0$

i.e.

$160-32t=0\\\\t=5\ s$

Put t = 5 s in equation (1). So,

$h(5)=160t-16t^2\\\\h(5)=160(5)-16(5)^2\\\\h(5)=400\ ft$

(c) When the ball reaches ground, its height is equal to 0. So,

h(t) = 0

$160t-16t^2=0\\\\t(160-16t)=0\\\\t=0,t=10\ s$

Hence, this is the required solution.

Can SOMEONE PLEASE HELP ME WILL GIVE 30 POINTS AND BRAINLIEST!!!!!

earnstyle [38]

Answer:

Hope i helped :)

Step-by-step explanation:

8) T-V =24

24 -6 =18

2x-18 =18

2x=0

x= 0/2

x=0

9)

*LMK

*L-K=x+3

*L-M=6x-10

*M-K= 3x-3

L-M + M-K = 6x -10 + 3x -3 = 9x -13

10 and 11)

Both lines are horizontal

both lines consist of intervals due to having 2 points on one line making it a distance between 2 points.

they are also concurrent lines because more then 3 lines pass through one point

they are also intersecting lines because they cross over each other
