Answer:

Vertex B to vertex Y

Step-by-step explanation:

The diagram shows two triangles ABC and XYZ. These triangles are congruent by SAS postulate, because

AB = XY = 25 cm;
AC = XZ = 29 cm;
∠A = ∠X = 36°.

Congruent triangles have congruent corresponding sides and angles, so translation and rotation must be completed such that

vertex A coincides with vertex X;
vertex B coincides with vertex Y;
vertex C coincides with vertex Z.

So, first, translate vertex B to vertex Y. Next, rotate ΔABC about B to align the sides and angles.

People are entering a building at a rate modeled by f (t) people per hour and exiting the building at a rate modeled by g (t) pe

erastova [34]

Answer:

The correct option is D) $f'(t)-g'(t) > 0$

Step-by-step explanation:

Consider the provided information.

People are entering a building at a rate modeled by f (t) people per hour and exiting the building at a rate modeled by g (t) people per hour,

The change of number of people in building is:

$h(x)=f(t)-g(t)$

Where f(t) is people entering in building and g(t) is exiting from the building.

It is given that "The functions f and g are non negative and differentiable for all times t."

We need to find the the rate of change of the number of people in the building.

Differentiate the above function with respect to time:

$h'(x)=\frac{d}{dt}[f(t)-g(t)]$

$h'(x)=f'(t)-g'(t)$

It is given that the rate of change of the number of people in the building is increasing at time t.

That means $h'(x)>0$

Therefore, $f'(t)-g'(t)>0$

Hence, the correct option is D) $f'(t)-g'(t) > 0$

Which of the following is True

DochEvi [55]

The first statement is true because when -10 is added to 24, it equals 14. You could also look at this problem as 24-10, which makes it easier to see that it equals 14.

The other choices are incorrect because they equal -11.4, -6, and -14, respectively.
