Answer:

<h2>First graph.</h2>

Step-by-step explanation:

Notice that in the piecewise functions, both parts have opposite slopes 2 and -2, that means the lines are perpendicular.

Also, the negative slope line must intercept y-axis at (0,3).

The positive slope line must intercept y-axis at (0,-1).

Additionally, the function indicates that to every x-value less than 1, the function is a decreasing line. And, for every x-value greater or equal than 1, the function is an increasing line.

Therefore, the first graph, represents the given piecewise function, because it has all the characteristics indicated by the function.

One positive integer is 7 less than twice another. The sum of their squares is 346. Find the integers. should be 2 answers

vovikov84 [41]

Answer:

the two positive integers are x= 15, and y = 11

Step-by-step explanation:

Let the first integer be x

Let the second integer be y

from the problem we can decode the following equations

$x=2y-7$ ---------------------------- equation 1

$x^{2} + y^{2}= 346$ -------------------------equation 2

substituting the value of x into equation 2, we have

$(2y-7)^{2} + y^{2}= 346 --------------equation 3$

expanding, we have

$4y^{2}-28y+49+y^{2}=346$

$5y^{2}-28y-297 = 0$

from this, y = 11 or y = -5.4

since our answer is a positive integer, we will have to pick the first value of y which is y = 11

substituting the value of y into equation 1, we have

$x= 2(11)-7=15$

hence x = 15

Therefore, we have x= 15, and y = 11

these are the two positive integers

The position function of a particle in rectilinear motion is given by s(t) = 2t^3 - 21t^2 + 60t + 3 for t ≥ 0. Find the position

avanturin [10]

Your first and second derivatives which are the velocity and the acceleration respectively are correct.
The particle has reverses direction when v(t) ≤ 0 so at interval 2 < t < 5 sec.
You can substitute now t = 2 for s(2) and a(2) for first changing direction. Also t = 5 for s(5) and a(5) for second changing direction.

James is x years old now and the sum of his age is and his brothers age is 10.

Vesnalui [34]

Answer:

1) James brother is 10-x years old

2) James was 3 years ago x-3 years old

3) James brother was 3 years ago 7-x years old

4) 3(x-3)=7-x

5) James is 4 years old, his brother is 6 years old

Step-by-step explanation:

3) 10 - x - 3 = 7 - x

5) 3* James age 3 years ago = James brothers age 3 years ago

<=> 3*(x-3) = 7-x

<=> 3x - 9 = 7 - x

<=> 4x = 16

<=> x = 4
