What is the image of the point (-7,9) after a rotation of 270 counterclockwise about the origin

1 answer:

8 0

Answer is (9, 7)

Step by step

Rule: 270 degrees counterclockwise about the origin our point A(x,y) becomes A'(y,-x).

This means, we switch x and y and make x negative.

So

(-7, 9) ➡️ ( 9, 7)

Find the area of a triangle with a base length of 3 units and a height of 4 units. 3 square units 6 square units 7 square units

yan [13]

For this case we have that by definition, the area of a triangle is given by:

$A = \frac {b * h} {2}$

Where:

b: It is the base of the triangle

h: It is the height of the triangle

According to the data of the statement we have:

$b = 3 \ units\\h = 4 \ units$

Substituting in the formula we have:

$A = \frac {3 * 4} {2} = \frac {12} {2} = 6 \ units ^ 2$

So, the area of the triangle is $6 \ units ^ 2$

Answer:

$6 \ units ^ 2$

Jazel time to check your progress. So far you have completed 816 miles which is 47% of the trail. Can you find about how many mi

musickatia [10]

Answer:

1,736.17miles

Step-by-step explanation:

Let the total trip be x miles

If 47% of the total trip is 816, then;

47% of x = 816

0.47x = 816

Divide both sides by 0.47

x = 816/0.47

x = 1,736.17miles

Hence the total miles for the trip is 1,736.17miles
