Write the equation that is the translation of y=|x| right 7 units and down 9 units.
DedPeter [7]

Answer:

y=|x-7|-9.

Step-by-step explanation:

The given function is  y=|x|.

When this function is translated to the right 7 units and down 9 units, then the equation becomes

y=|x-7|-9.

Always remember that; y=|x-c|-k is a transformation that translates the graph of y=|x| c units to the right and k units down.

The correct choice is the first option.

Can someone please help ​
3241004551 [841]

Answer:

x=3, y= - 2

Step-by-step explanation:

4x + 3y = 6

x-3y= 9

x=9+3y

4.(9+3y)+3y=6

36+12y+3y=6

15y = - 30

y = - 2

=> x= 9+3y

x= 9+ 3.(- 2)

x= 3

A punter on Westview High School's football team kicks a ball straight up from 5 feet above the ground with an initial upward ve
Naily [24]
This can solved graphically, using algebraic manipulation or differential calculus.

Plotting the equation will generate a parabola. The vertex represents the point where the ball will reach the maximum height.

The vertex can be determined by completing the square
h = -16t2 + 45t + 5
h - 5 = -16(t2 - 45/16t)
h - 5 - 2025/64 = -16(t2 - 45/16t + 2025/1024)
(-1/16)(h - 2345/64) = (t - 45/32)^2

The vertex is
(45/32,2345/64) or (1.41,36.64)

The maximum height is 36.64 ft

Using calculus, taking the first derivative of the equation and equating to 0
dh/dt = 0 = -32t + 45
t = 45/32
Substituting this value to the equation
h = -16(45/32)^2 + 45(45/32) + 5
h = 36.64 ft

Round to the nearest gram
earnstyle [38]

Alright, so after a half-life, half of the previous number would be left. So basically,

180 g ← 0 half lives

90 g ← 1 half life

45 g ← 2 half lives

22.5 g ← 3 half lives

11.25 g ← 4 half lives


Therefore, the answer is 11.25 grams
