Mathematics

Answer:

D. ASA

Step-by-step explanation:

In triangles ABC and ADC,

  • Angles BCA and DAC are congruent (from the diagram);
  • Angles BAC and DCA are congruent (from the diagram);
  • AC is congruent AC (by reflexive property).

So, the triangles ABC and CDA are congruent by ASA postulate.

ASA (Angle-Side-Angle) postulate states that if two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the triangles are congruent.

Answer to problem 1 is (-4, 4)

Answer to problem 3 is (2, 2)

=====================================

Explanation:

When the center of a dilation is the origin (0,0), we simply multiply the scale factor by each coordinate.

For problem 1, point U is located at (-2,2). Multiply each coordinate by the scale factor 2 (since it says "dilation of 2") to get (-4,4)

For problem 3, we multiply 0.5 by each coordinate of the point U(4, 4) getting to U ' (2,2)

--------------

The dilation rule used here is (x,y) \to (kx, ky) where k is the scale factor or dilation factor. This rule only applies if the center of dilation is (0,0). For other centers, you'll need to apply a translation first, dilate, then translate back again.

If k > 1, then the point moves further away from the origin.

If 0 < k < 1, then the point moves closer to the origin.

An oil storage tank ruptures at time t = 0 and oil leaks from the tank at a rate of r(t) = 85e−0.04t liters per minute. How much
Furkat [3]
Given the rate of water flow is given by:
r(t)=85e^(-0.04t)
thus the amount of water flow in the first hour when t=1, will be:
r(1)=85e^(-0.04*1)
=81.667
thus the amount of water that flowed out will be:
85-81.667
=3.333 liters
