Answer: The tree has to be 60 feet tall
Step-by-step explanation: Jerry’s shadow is a third of Jerry, that means the Tree’s shadow is only a third of the tree. To find the tree’s height you have to multiply the shadow by 3, 20 multiplied by 3 is 60.
Triangle FGH is graphed on the coordinate plane below.
On a coordinate plane, triangle F G H has points (negative 6, negative 8), (negative 2, negative 3), (negative 4, negative 2).
The figure is rotated 180° using the origin as the center of rotation. How do the coordinates of the vertices of the preimage compare to the coordinates of the vertices of the image?
(x, y) right-arrow (y, x)
(x, y) right-arrow (negative y, negative x)
(x, y) right-arrow (negative x, negative y)
(x, y) right-arrow (x, negative y)
Answer:
(x, y) right-arrow (negative x, negative y) ⇒ (x, y) → (-x, -y)
Step-by-step explanation:
Let us revise the rotation about the origin
If point (x, y) rotated about the origin by angle 90° counterclockwise (or 270° clockwise), then its image is (-y, x) . The rule is (x, y) → (-y, x)If point (x, y) rotated about the origin by angle 180° counterclockwise ( or 180° clockwise), then its image is (-x, -y) . The rule is (x, y) → (-x, -y)If point (x, y) rotated about the origin by angle 270° counterclockwise (90° clockwise), then its image is (y, -x) . The rule is (x, y) → (y, -x)Let us solve the question
∵ The vertices of triangle FGH are (-6, -8), (-2, -3), (-4, -2)
∵ The figure is rotated 180° using the origin as the center of rotation
→ By using the 2nd rule above
∴ The vertices of its image are (6, 8), (2, 3), (4, 2)
∴ The rule is (x, y) → (-x, -y)
The coordinates of the vertices of the preimage compare to the coordinates of the vertices of the image do (x, y) right-arrow (negative x, negative y) ⇒ (x, y) → (-x, -y)

How to calculate the area of this?
Answer:
1601 m²Step-by-step explanation:
Split the quadrilateral into 2 triangles as pictured
One of them is right triangle with 2 sides known
The third side is the hypotenuse and is:
√(60²+25²) = √4225 = 65 mTotal area is the sum of the areas of the 2 triangles
A= A1 + A2Area 1
A1 = 1/2*15*60 = 750 m²Use Heron's formula for the second triangle:
A2 = 1/4√(65 + 64 + 27)(-65 + 64 + 27)(65 - 64 + 27)(65 + 64 - 27) ≈ 851m²Total area
A = 750 + 851 = 1601 m²Sonya works on a cruise ship and sleeps in a cabin that is 6 feet below sea level. The main deck is 35 feet above Sonya's cabin. How far above sea level is the main deck? add unit of measure!*
Answer: 29 ft above sea level
Step-by-step explanation:
if she is 6 feet under that could be considered -6, the main deck is above sea level so +35, so it would be 35-6=29 ft

What is the measure of angle x?
64°
X
45
109
64
180
71
Answer:
A
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
x is an exterior angle of the triangle, thus
x = 64° + 45° = 109° → A
Answer:
A
Step-by-step explanation:
64+45=109
180-109=71
180-71=109 *

Written as a simplified polynomial in standard form, what is the result when
(3x – 2)2 is subtracted from 4x?
Answer:
Yes, will be
[tex](3x - 2)2 = 6x - 2 = 4x[/tex]
Because the 4x it doesn't t affect the 6x and the 6x is

the cube of twice a number
Answer:
The cube of twice a number.
Twice a quantity usually indicates to take two of the things in question; usually this indicates to multiply by 2. Thus "twice a number x" can be written symbolically as 2x. If this is part of a problem, say twice a number x is 6, then we can rewrite algebraically as 2x=6; dividing both sides by 2 yields x=3.

Answer:
The slope is -1/3 I think.
Answer:
slope = 1/3
Step-by-step explanation:
We can look at the points where the graph exactly intersects a point. Those points are: (10, 50), (40, 60), and (70, 70). The slope is the difference of y divided by the difference of x. You can subtract any two points. Your final answer would be (70-60)/(70-40) = 10/30 = 1/3
