Choose the option that best answers the question.The points A(0, 0), B(0, 4a – 5) and C(2a + 1, 2a + 6) form a triangle. If Angl

Sunny_sXe [5.5K]

Answer:

The correct option is 1.

Step-by-step explanation:

Given information: The coordinates of a right angled triangle ABC are A(0, 0), B(0, 4a – 5) and C(2a + 1, 2a + 6). Angle ABC = 90°.

It means AB and BC are legs of the right angled triangle ABC.

Side AB lies on the y-axis because the x-coordinate of both A and B is 0.

Two legs are perpendicular to each other. So, BC must be parallel to x-axis and the y-coordinate of both B and C is must be same.

$4a-5=2a+6$

$4a-2a=5+6$

$2a=11$

Divide both sides by 2.

$a=\frac{11}{2}$

The value of a is 2. So the coordinates of triangle ABC are

$B(0,4a-5)=B(0,4(\frac{11}{2})-5)\Rightarrow B(0,17)$

$C(2a+1,2a+6)=C(2(\frac{11}{2})+1,2(\frac{11}{2})+6)\Rightarrow C(12,17)$

The area of a triangle is

$Area=\frac{1}{2}|x_1(y_2-y_3)+x_2(y_3-y_1)+x_3(y_1-y_2)|$

The area of triangle ABC is

$Area=\frac{1}{2}|0(17-17)+0(17-0)+12(0-17)|$

$Area=\frac{1}{2}|12(-17)|$

$Area=\frac{1}{2}|-204|$

$Area=\frac{1}{2}(204)$

$Area=102$

The area of triangle ABC is 102. Therefore the correct option is 1.

Matt needs to swim 8 meters in 25 seconds yo qualify as a state swimer. Which unit rate describes the speed Matt needs to swim

fiasKO [112]

Answer:

Option D, 0.32 meters per second

Step-by-step explanation:

Step 1: Find the unit rate at which Matt needs to swim

Make an equation to represent the scenario.

25m = 8

Step 2: Solve for m by dividing both sides by 25

25m / 25 = 8 / 25

m = 0.32

Step 3: Check

To check, you can multiply the number of second, 25, by the meters per second to see if you get the total meters, 8.

0.32 * 25

8

So, the answer is correct :)

0.32 means that Matt needs to swim 0.32 meters per second to qualify as a state swimmer.

Answer: Option D, 0.32 meters per second
