In the rectangle below, SU= 4x-2, RT = 5x-10, and m ZSVT= 84º.

stepladder [879]

Answer:

RV = 15, ∠ VUR = 48°

Step-by-step explanation:

The diagonals of a rectangle are congruent , so

RT = SU , that is

5x - 10 = 4x - 2 ( subtract 4x from both sides )

x - 10 = - 2 ( add 10 to both sides )

x = 8

Then

RT = 5x - 10 = 5(8) - 10 = 40 - 10 = 30

The diagonals bisect each other , then

RV = 0.5 × 30 = 15

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

∠ RVU = ∠ svt = 84° ( vertical angles )

RV = UV ( diagonals are congruent and bisect each other )

Then Δ RVU is isosceles with base angles congruent , then

∠ VUR = $\frac{180-84}{2}$ = $\frac{96}{2}$ = 48°

What is the acceleration of the object in the graph?

aleksandr82 [10.1K]

Answer:

-0.8 m/s^2

Step-by-step explanation:

Acceleration is the slope of the velocity curve. Here the velocity decreases from 12 m/s to zero in 15 seconds. So, the slope is ...

(-12 m/s)/(15 s) = -0.8 m/s^2

For the angle 0 = 150° moving counter-clockwise in standard position, determine which

Kitty [74]

Answer: Start at the positive

-axis, then rotate left by the desired angle.

Explanation-

Standard position means the first arm of the angle is the positive

-axis, and the other arm is placed by rotating counter-clockwise from there, by the amount of the angle.

As a basic example, the symbol

∠

is about a 45° angle in standard position.

To get a feel for where the second arm (called the "terminal arm") will go, remind yourself that the axes themselves meet each other at 90°.

If our angle was 90°, the terminal arm would be on the positive

-axis.

If our angle was 180°, it would be on the negative

-axis.

Wait! 180° is more than 150°, so our angle is somewhere in quadrant 2. In fact, 150° is 2/3 of the way between 90° and 180°, so our terminal arm will be 2/3 of the way into quadrant 2.

(ignore the part of the line in quadrant 4)
