Prove Quadrilateral P(-2, 3) L( 2, 6) U (7,6) S(3, 3) is a rhombus
Answer:
The quadrilateral is a rhombus
Step-by-step explanation:
Prove Quadrilateral P(-2, 3) L( 2, 6) U (7,6) S(3, 3) Is a rhombus
A rhombus is a quadrilateral with all its sides equal to each other.
We prove this using the formula
√(x2 - x1)² + (y2 - y1)²
When given vertices (x1, y1) and (x2, y2)
For sides PL
P(-2, 3) L( 2, 6)
√(2 - (-2))² + (6 - 3)²
= √4² + 3²
= √16 + 9
= √25
= 5 units
For sides LU
L( 2, 6) U (7,6)
√(7 - 2)² + (6 - 6)²
= √5²
= √25
= 5 units
For side US
L( 2, 6) U (7,6)
= √(7 - 2)² + (6 - 6)²
= √5² + 0²
= √25
= 5 units
P(-2, 3), S(3, 3)
= √(3 - (-2))² + (3 - 3)²
= √5² + 0²
= √25
= 5 units
From the above calculation,
PL = LU = US = PS = 5 units
Hence, the above quadrilateral is a rhombus

To find:
The equivalent expression.
Solution:
We have,

It can be written as:
[tex]=\dfrac{60}{5}\times \dfrac{m^{-2}}{m^{-4}}\times \dfrac{n^6}{n^{-2}}[/tex]
[tex]=12\times m^{-2-(-4)}\times n^{6-(-2)}[/tex] [tex][\because \dfrac{a^m}{a^n}=a^{m-n}][/tex]
[tex]=12\times m^{-2+4}\times n^{6+2}[/tex]

Find the volume of a cone with a height of 6cm and a base radius of 4cm. Use the value 3.14 for π, and do not do any rounding.
Answer:
100.48 cm³
Step-by-step explanation:
Volume of a cone, V = 1/3 * pi * r² * h
Radius, r = 4 cm ; h = 6cm
V = 1/3 * 3.14 * 4² * 6
V = 1/3 * 3.14 * 16 * 6
V = 3.14 * 16 * 2
V = 3.14 * 32
V = 100.48 cm³
Hence, the volume of the cone is 100.48 cm³

hi can someone help me with this?
Answer:
h = 4.5 units
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )
Here A = 6.75 and b = 3 , then
[tex]\frac{1}{2}[/tex] × 3h = 6.75
1.5h = 6.75 ( divide both sides by 1.5 )
h = 4.5
we have
base [b]=3 units
height [h]=x units
area of triangle =6.75 square units
we have
area of triangle =1/2 b×h
6.75 square units =1/2×3×x
x=6.75×2/3=4.5units
so height is 4.5 units.

Find the area of the regular polygon. Round your answer to the nearest whole number of square units.
Answer:
total area = 39.6 square units
Step-by-step explanation:
determine the inside angle
360 / 5 = 72°
half of the triangle = 36°
given:
adj = 3.3
Ф = 36°
length of the opp of a small triangle is = adj. tan Ф
opp = 3.3 * tan 36 = 2.4
area of a triangle = 1/2 b * h x 2 tringles
area =( 1/2 * 2.4 * 3.3 ) * 2
area = 7.92 multiplied by 5 equal shapes
total area = 7.92 * 5
total area = 39.6 square units
hope this helps
mark me as a brill please
good luck
The total area of the regular polygon should be considered as the 39.6 square units.
Calculation of the total area of the regular polygon:But before that following things should be calculated
first determine the inside angle i.e.
[tex]= 360 / 5[/tex]
= 72°
Now
half of the triangle = 36°
Since
adj = 3.3
Ф = 36°
So,
opp =[tex]3.3 * tan 36[/tex] = 2.4
Now
area of a triangle =[tex]1/2 b * h * 2[/tex]
[tex]=( 1/2 * 2.4 * 3.3 ) * 2\\\\= 7.92 * 5[/tex]
= 39.6 square units
hence, The total area of the regular polygon should be considered as the 39.6 square units.

The function g(x) is a translation of f(x) = (x + 3)2 – 10. The axis of symmetry of g(x) is 5 units to the right of f(x) . Which function could be g(x)?
g(x) = (x – 2)2 + k
g(x) = (x + 8)2 + k
g(x) = (x – h)2 – 5
g(x) = (x – h)2 – 15
Answer:
a.
g(x) = (x – 2)2 + k
Step-by-step explanation:
The function that could be g(x) is (a) g(x) = (x - 2)^2 + k
How to determine the function?The function f(x) is given as:
f(x) = (x + 3)^2 - 10
The axis of symmetry of g(x) is 5 units to the right of f(x).
This means that:
g(x) = f(x - 5)
So, we have:
f(x - 5) = (x - 5+ 3)^2 + k
Evaluate the difference
f(x - 5) = (x - 2)^2 + k
Substitute g(x) = f(x - 5)
g(x) = (x - 2)^2 + k
Hence, the function that could be g(x) is (a) g(x) = (x - 2)^2 + k

A 25-foot ladder is leaned against a wall. If the base of the ladder is 7 feet from the wall, how high up the wall will the ladder reach?
Answer:
24ft
Step-by-step explanation:
Pythagorean Theorem!!
[tex]a^2 + b^2 = c^2[/tex]
------------------------
In this case, the ladder is c, and the base is b.
------------------------
Plug the numbers in the formula.
[tex]a^2 + 7^2 = 25^2[/tex]
------------------------
Solve.
[tex]a^2 + 49 = 625[/tex]
[tex]a^2 -49 = 625 - 49[/tex]
[tex]a^2 = 576[/tex]
[tex]\sqrt{a^2} = \sqrt{576}[/tex]
[tex]a = 24[/tex]
Awad claims that when m is a negative integer and n is a positive integer, n - m is always negative. Is Awad’s claim true or false? Explain your reasoning. If it is true, give an example to support his claim. If it is false, give a counterexample. Explain your reasoning..
Answer:
False
Step-by-step explanation:
False, because whenever you subtract a negative number, you always end up adding because two negatives make a positive. Lets say n is 4 and m is -3, 4-(-3) is going to turn into 4+3=7.
The Awad'claims that "when m is a negative integer and n is a positive integer, n - m is always negative". which is false.
What is the number system?A number system is defined as a way to represent numbers on the number line using a set of symbols and approaches. These symbols, which are known as digits, are numbered 0 through 9. Based on the basic value of its digits, different types of number systems exist.
Awad claims that when m is a negative integer and n is a positive integer, n - m is always negative.
The above claim is false because subtracting a negative integer always results in an addition because two negatives equal a positive.
For example, n is 6 and m is -2; 6 -(-2) will equal 6 + 2 = 8.
Hence, the Awad'claims that "when m is a negative integer and n is a positive integer, n - m is always negative". which is false.

Answer:
The angle between the ramp and the horizontal is 11.54 degrees
Step-by-step explanation:
Here, we want to get the angle between the ramp and the horizontal
What we have to do here is to bring the measure of 2 m near to the edge leftwards, so we can have a right triangle
Now, the angle we want to calculate is the angle that faces the measure 2 m
The given measure of 10 m will represent the hypotenuse of the right triangle
The trigonometric ratio that links the hypotenuse and the opposite is the sine
The sine is the ratio of the opposite to the hypotenuse
Thus, we have it that;
sin theta = opp/hyp
sin theta = 2/10
sin theta = 0.2
theta = sin^-1 0.2
theta = 11.54
