You rotate triangle ABC, with vertices A(-3, 1), B(-2, 2), and C(-3, 4), 90° counterclockwise about the origin to form triangle

zhenek [66]

Answer:

A'(-1,-3)

B'(-2,-2)

C'(-4,-3)

Step-by-step explanation:

The rotation by 90° counterclockwise about the origin has the rule

$(x,y)\rightarrow (-y,x)$

So, the vertices of the triangle ABC have the images:

$A(-3,1)\rightarrow A'(-1,-3)\\ \\B(-2,2)\rightarrow B'(-2,-2)\\ \\C(-3,4)\rightarrow C'(-4,-3)$

see attached diagram for details.

What is the perimeter of the triangle shown on the coordinate plane, to the nearest tenth of a unit?

RSB [31]

The perimeter of the traingle shown on the coordinate plane of points (-3, 3), (3, 4),and (3,-3) is 21.6 units. The length of one sides of the triangle is 6.1, 8.5 and 7 units. To calculate the perimeter of a triangle just add all the sides.

Use the given probability value to determine whether the sample results could easily occur by chance, then form a conclusion. A

Wittaler [7]

Answer:

It appears that there ▼ is is not sufficient evidence to conclude that pregnant women can correctly predict the gender of their baby.

Step-by-step explanation:

The results occur by chance.

There's not enough evidence to show that the pregnant women can predict the gender of the babies. 0.327 probability of getting such sample results by chance means 1-0.325 = 0.675 women are unable to predict the gender.

This 0.675 tells us that more than 67 % of the women are unable to predict the gender.

The other option is incorrect .

The probability shows that the sample results ▼ could not have easily occurred by chance.

The probability does not show how the sample results are affected by chance. There' s no increase in the number of trials , there's no evidence of how they guessed.

A tennis player hits a ball 3 feet above the ground with a velocity of 60 ft/sec. After how many seconds will the ball be at a h

9966 [12]

Answer:

The ball will be at a height of 3 feet above the ground after 3.729 seconds.

Step-by-step explanation:

Let suppose that the tennis player has hit the ball vertically, meaning that ball will experiment a free fall, that is, an uniform accelerated motion due to gravity. The time taken by the ball in terms of its initial velocity ( $v_{o}$ ), in feet per second, initial position ( $x_{o}$ ), in feet, final position ( $x$ ), in feet, and gravitational acceleration ( $g$ ), in feet per square second is described by this second order polynomial:

$x = x_{o} + v_{o}\cdot t + \frac{1}{2}\cdot g\cdot t^{2}$ (1)

If we know that $x_{o} = x = 3\,ft$ , $v_{o} = 60\,\frac{ft}{s}$ and $g = -32.174\,\frac{ft}{s^{2}}$ , then the time needed by the ball to be at a height of 3 feet again is:

$3\,ft = 3\,ft + \left(60\,\frac{ft}{s} \right)\cdot t + \frac{1}{2}\cdot \left(-32.174\,\frac{ft}{s^{2}} \right)\cdot t^{2}$

$-16.087\cdot t^{2}+60\cdot t = 0$ (2)

$t^{2} - 3.729\cdot t = 0$

$t \cdot (t -3.729) = 0$

The binomial contains the time when the ball will be at a height of 3 feet again. In other words, the ball will be at a height of 3 feet above the ground after 3.729 seconds.
