Answer:
C.
Step-by-step explanation:
To find the area of a triangle, one must multiply the base by the height then divide by 2.
So, the area of this triangle would be 7.5
<u><em>≡ Solution:</em></u>
<em>⇔ To make it easier:</em>
⇒ ²¹/₂₅ × ⁴/₄
⇒ ⁸⁴/₁₀₀
<u>⇒ 0,84</u>
Answer: third choice (4 - 9).
Explanation:
1) The first reflection, Ry = - 5, means a reflection is across the line y = - 5
2) Since the point P has y-coordinate - 1, its discance to the line y = - 5 is 4 units (P is located 4 units upper the line y = - 5).
Then, the reflection of the y-coordinate will be 4 units below the line y = - 5, which is -5 - 4 = - 9,
Therefore, the y-coordinate of the image is - 9.
3) The second reflection, Rx = 1, means a reflection across the line x = 1.
4) Since the point P has x-coordinate - 2, its distance to the line x = 1 is 3 units (P is located 3 units to the left of the line x = 1).
Then, the reflection of P will be 3 units to the right of the line x = 1.
That is 1 + 3 = 4.
Therefore, the x-coordinate of the image is 4.
5) You have obtained the x and y - coordinates of the image, x = 4 and y = -9, that is (4, - 9) which is the third choice.
A 3x with an exponet of 3
Answer:
5 units
Step-by-step explanation:
From the coordinates, we have;
x1 = -5
x2 = -1
y1 = 5
y2 = 2
Now,from the distance formula, distance is;
d=√((x2 - x1)²+(y2 - y1)²)
Plugging in the relevant values, we have;
d = √((-1 + 5)²+(2 - 5)²)
d = √(16 + 9)
d = √25
d = 5
