Function A is a quadratic function with a vertex at (3, 4) and a leading coefficient of -1 Function B has the equation y = |x +
skad [1K]

With the information given, we deduce that the parabola is

y=-(x-3)^2+4 = -(x^2-6x+9)+4 = -x^2+6x-5

Reflecting a function over the x axis means to change its sign. After the reflection, the parabola becomes

y=x^2-6x+5

And to shift down a function, you subtract the shift from the equation: the equation becomes

y=x^2-6x+5-2=x^2-6x+3

Similarly, the other function is reflected over the x axis (sign change) and shifted up 3 (add 3 to the equation):

|x+2|\mapsto -|x+2|\mapsto -|x+2|+3

In order to compute the y intercept, we simply have to evaluate the functions at x=0: for the parabola we have

y(0)=3

For the other function, we have

y(0)=-|2|+3=-2+3=1

△DEF is shown below.<br><br>Triangle DEF<br><br>What is m∠DEF?​
S_A_V [24]

Answer:

m∠DEF = 50

Step-by-step explanation:

∠DEG = ∠GEF

3y + 4 = 5y - 10

subtract 4 from both sides

3y = 5y - 14

subtract 5y from both sides

-2y = -14

divide by -2

y = 7

Add 7 into the equations:

3y + 4 + 5y - 10

3(7) + 4 + 5(7) - 10

21 + 4 + 35 - 10

25 + 25

50

Exercise
svp [43]

By addition of all the exercise and substracting it from 1 hourJavier runs on treadmill on Monday is 0.40 hour.

Now According to the question javier completed 3 repetitions of each exercise so by multiplication time taken by javier to complete each exercise is as follow;

Squats = 0.8*3= 0.24 hour

Crunches = 0.03*3 = 0.09 hour

Lunges = 0.04*3 = 0.12 hour

curls = 0.05*3 = 0.15 hour

we can calculate total time taken to complete all exercise by Addition is,

0.24 + 0.09 + 0.12 + 0.15

0.60 hour

time taken on treadmill by javier;

1 hour - 0.60 hour

0.40 hour
