ABCD is a parallelogram.
AD = 12 cm.
DC = 9 cm.
The perpendicular distance of
from CD is 8 cm.
What is the perpendicular distance of AD from BC?
9514 1404 393
Answer:
6 cm
Step-by-step explanation:
The area of the parallelogram is the same, either way you figure it.
A = bh
A = CD(length ⊥ to CD)
A = (9 cm)(8 cm) = 72 cm²
__
A = AD(length ⊥ AD)
72 cm² = (12 cm)(length ⊥ AD)
(length ⊥ AD) = (72 cm²)/(12 cm) = 6 cm
The perpendicular distance of AD from BC is 6 cm.

6. A girl is riding her skateboard down a hill. She speeds up as she goes down the hill, and the wheels get a little warmer. Saved to this PC What energy transformations happen while she is going down the hill?
A. Motion energy (kinetic energy) is transformed into gravitational potential energy an thermal energy
B. Gravitational potential energy is transformed into motion energy (kinetic energy) and thermal energy. C. Gravitational potential energy is transformed only into motion energy (klnetic energy).
D. No energy transformations are involved while she is going down the hi D
Answer:
B
Explanation:
the wheels are getting warmer so it would have to be thermal energy, hope this helps :)
Gravitational potential energy is transformed into motion energy ,kinetic energy and thermal energy.
We know that Gravitational potential energy is the potential energy with respect to the gravitational force. To possess gravitational potential energy, the object to be placed in a position in the gravitational field.
What is potential energy?Potential energy of body is the energy generated by virtue of the position of the body. Whereas kinetic energy is generated by virtue of its movement.
Potential energy and kinetic energy together called as mechanical energy. The potential energy is mathematically expressed as;
p = mgh.
Here, g s gravity, h is height and m is the mass.
The gravitational potential energy can be arised in an object due the position in gravitational field. That changes with the change in position and change in height from the ground.
Hence Gravitational potential energy is transformed into motion energy (kinetic energy) and thermal energy.

Find the value of x, what makes r parallel to s
Answer:
a. x = 14 (see explanation)
b. the arrows along the lines
Step-by-step explanation:
The relationship of these two expressions is Same Side, which means their sum is 180.
plugging in
108 + 4x + 16 = 180 | Given
124 + 4x = 180 | Add the numbers
4x = 56 | Subtract 124 from both sides
x = 14 | Divide both sides by 4

Answer:
HOPE THAT WAS TRUE
Step-by-step explanation:
[tex] - 3 + \sqrt{m + 59} = m \\ \sqrt{m + 59} = m + 3 \\ {(m + 59)}^{ \frac{1}{2} } = m + 3 \\ \frac{1}{2} log(m + 59) = log(m + 3) \\ 0.5 log(m) + 0.5 log(59) = log(m)+log(3) \\ 0.5 log(m) = 0.5 log(59) - log(3) \\ [/tex]
[tex]0.5 log(m) = 0.885 - 0.477 \\ 0.5 log(m) = 0.408 \\ log(m) = 0.816[/tex]
[tex]m = {10}^{0.816} = 6.556[/tex]

Answer:
x=29.25
Step-by-step explanation:
The arc length and the angle are the same when the angle is at the center.
so we setup and equation
4x-5=112 and solve for x
step 1
add 5 to each side
4x-117
step 2 divide each side by 4
x=29.25
Answer:
x=29.25
Step-by-step explanation:
Arc CD is the same as angle COD

Find the area of the following figure and choose the appropriate result.
Area is the entire amount of space occupied by a flat (2-D) surface or an object's shape. The area of a plane figure is the area that its perimeter encloses. The quantity of unit squares that cover a closed figure's surface is its area.
We have a figure consist of Square and Triangle.
So, Area of Figure
= Area of Square + Area of Triangle
= 11.1 x 11.1 + 1/2 x 11.1 x 11.4
= 123.21 + 11.1 x 5.7
= 186.48 square cm
Thus, the required Area is 186.48 square cm.

The nth term of a sequence is 3n²-1
The nth term of a different sequence is 30–n²
Find the only number that is in both of these sequences.
Answer: The number is 26.
Step-by-step explanation:
We know that:
The nth term of a sequence is 3n²-1
The nth term of a different sequence is 30–n²
We want to find a number that belongs to both sequences (it is not necessarily for the same value of n) then we can use n in one term (first one), and m in the other (second one), such that n and m must be integer numbers.
we get:
3n²- 1 = 30–m²
Notice that as n increases, the terms of the first sequence also increase.
And as n increases, the terms of the second sequence decrease.
One way to solve this, is to give different values to m (m = 1, m = 2, etc) and see if we can find an integer value for n.
if m = 1, then:
3n²- 1 = 30–1²
3n²- 1 = 29
3n² = 30
n² = 30/3 = 10
n² = 10
There is no integer n such that n² = 10
now let's try with m = 2, then:
3n²- 1 = 30–2² = 30 - 4
3n²- 1 = 26
3n² = 26 + 1 = 27
n² = 27/3 = 9
n² = 9
n = √9 = 3
So here we have m = 2, and n = 3, both integers as we wanted, so we just found the term that belongs to both sequences.
the number is:
3*(3)² - 1 = 26
30 - 2² = 26
The number that belongs to both sequences is 26.

Fill in the table using this function rule.
y=26-4x
The complets table of values for the function rule
x 1 2 4 6
y 22 18 10 2
Completing the table of values for the function ruleFrom the question, we have the following parameters that can be used in our computation:
y = 26 - 4x
The missing y values are at x = 1, 2, 4 and x = 6
Substitute the known values in the above equation, so, we have the following representation
y = 26 - 4(1) = 22
y = 26 - 4(2) = 18
y = 26 - 4(3) = 10
y = 26 - 4(6) = 2
So, the missing values are 22, 18. 10 and 2
