Give two reasons why this shape is a square when x=5.
Answer:
First of all, we can see that this shape have 4 90° angles.
Secondly, since x = 5 we have:
3 × 5 -2 = 15 - 2 = 13 (cm)
And: 5 + 8 = 13 (cm)
=> The two adjacent sides that make up the angle is equal to each other
So this shape is a quare.
=> This shape is a square.

21. Find the perimeter of the triangle: 60 degrees, 60 degrees,
[tex]4 \sqrt{15 } [/tex]
Answer:
120+ 4(square root)15
120+15.49=135.49
135.49 is the perimeter
The perimeter of the triangle having two angles 60 degrees, 60 degrees, and one side [tex]4\sqrt{15}[/tex] is, [tex]12\sqrt{15}[/tex] or 46.47
What is the perimeter?Perimeter is a mathematical term, which means total outer boundary of a figure, we define it only for two dimensional figures.
Perimeter = Sum of length of the all the sides
Given that,
the triangle having two angles 60 degrees, 60 degrees,
and one side
It is known that, total sum of all the angles of triangle is 180°
A = 60°
B = 60°
C = ?
A + B + C = 180°
60° + 60° + C = 180°
C =60°
Hence, it is a equilateral triangle
And for equilateral triangle length of all sides are equal
a = [tex]4\sqrt{15}[/tex]
b = [tex]4\sqrt{15}[/tex]
c = [tex]4\sqrt{15}[/tex]
Perimeter = [tex]4\sqrt{15}[/tex] + [tex]4\sqrt{15}[/tex] + [tex]4\sqrt{15}[/tex]
Perimeter = 12√15
So, the perimeter is 12√15

The measure of <ACD is 120. Find the measure of <ACB, <BCD, and <ACE.
Explain how you found the measure of <ACE.
Answer:
m∠ACB = 39°
m∠BCD = 81°
m∠ACE = 60°
Step-by-step explanation:
From the picture attached,
m∠ACD = 120°
Since, m∠ACD = m∠ACB + m∠BCD
x + (2x + 3) = 120°
3x + 3 = 120
3x = 117
x = 39
Therefore, m∠ACB = 39°
m∠BCD = (2x + 3) = 2(39) + 3
= 81°
Since, m∠ACE + m∠ACB + m∠BCD = 180° [Angles formed at a point on a straight line]
m∠ACE + 39 + 81 = 180
m∠ACE = 180 - 120
m∠ACE = 60°

in math class, the girl to boy i 8 to 6. if there are 24 girl in the class, how many boy are there?
Answer:
[tex]\huge\boxed{\text{18 boys}}[/tex]
Step-by-step explanation:
This is basically just a ratio. If the ratio between the amount of girls to the amount of boys is 8 to 6, then we can create a fraction (girls/boys)
[tex]\frac{8}{6}[/tex]
Using what we know about the second statement (24 girls) we can make a ratio like this (also assuming girls/boys)
[tex]\frac{24}{x}[/tex]
Since the ratios must be equal, we can set them equal to each other.
[tex]\frac{8}{6} = \frac{24}{x}[/tex]
We can cross multiply to find x.
[tex]24 \cdot 6 = 144\\\\144 \div 8 = 18[/tex]
So there are 18 boys.

The position of an object at time t is given by s(t) = -8 - 9t. Find the instantaneous velocity at t = 1 by finding the derivative. plz show work
Answer:
The instantaneous velocity at t = 1 will be:
[tex]\frac{d}{dt}\left(-8-9t\right)=-9[/tex]Step-by-step explanation:
Given the position of an object at a time [tex]t[/tex]
[tex]s\left(t\right)=-8-9t[/tex]
As we know that determining the derivative of the position function with respect to time t would give us the instantaneous velocity, so
[tex]\frac{ds}{dt}=\frac{d}{dt}\left(-8-9t\right)[/tex]
Applying the sum/difference rule:
[tex]\left(f\pm g\right)'=f\:'\pm g'[/tex]
[tex]\frac{ds}{dt}=-\frac{d}{dt}\left(8\right)-\frac{d}{dt}\left(9t\right)[/tex]
as
[tex]\frac{d}{dt}\left(8\right)=0[/tex] ∵ [tex]\frac{d}{dx}\left(a\right)=0[/tex]
and
[tex]\frac{d}{dt}\left(9t\right)=9[/tex] ∵ [tex]\mathrm{Take\:the\:constant\:out}:\quad \left(a\cdot f\right)'=a\cdot f\:'[/tex] and [tex]\frac{d}{dt}\left(t\right)=1[/tex]
so the expression becomes
[tex]\frac{ds}{dt}=-\frac{d}{dt}\left(8\right)-\frac{d}{dt}\left(9t\right)[/tex]
[tex]=-0-9[/tex]
[tex]=-9[/tex]
As the derivative is constant.
Therefore, the instantaneous velocity at t = 1 will be:
[tex]\frac{d}{dt}\left(-8-9t\right)=-9[/tex]

How do you describe the principal square root of the 34? *
A. The square root of 34 is a rational number.
B. The square root of 34 is an irrational number.
C. The square root of 34 is not defined.
D. The square root of 34 can be a positive or negative number.
Answer:
B. The square root of 34 is an irrational number.
Step-by-step explanation:
The square root of 34 is a rational number if 34 is a perfect square.
Since 34 is not a perfect square, it is an irrational number.
Since the square root of 34 is not a perfect square, hence, the square root of 34 is an irrational number: Option B is correct.
Irrational numbers are numbers that cannot be written as a ratio of two integers.
Examples of irrational numbers are surd functions, euler's number, pi value.Most terminated decimals are also irrational numbers.Since the square root of 34 is not a perfect square, hence, the square root of 34 is an irrational number.

Answer:
Once an expression has been factored, use the Distributive Property to expand the expression. The expanded expression should be the original expression.
Step-by-step explanation:
The distributive property for any binary operation Ф under * in the given set S where a, b, c ∈ S
The binary operation a * (b Ф c) = (a * b) Ф (a * c) .
The operation * distributes over the operation Ф.
Now, when factoring, suppose we have an expression ab + ac. To factor this, we have a(b + c).
To check that our answer is correct, since the expression has been factored, we then distribute the multiplication over the addition to check if the factorization is correct.
So, a(b + c) = ab + ac which is our initial expression.
So, to use the distributive property to check work when factoring, once an expression has been factored, use the Distributive Property to expand the expression. The expanded expression should be the original expression.
The way to use the Distributive Property to check your work when factoring is;
Option D; Once an expression has been factored, use the Distributive Property to expand the expression. The expanded expression should be the original expression.
The distributive property in algebra is expressed as; a(b + c) = ab + ac
Now, to use the distributive property to check the work when factoring, we have to expand the factored form first.
For example, we have; 2(3 + 4)
From distributive property, we have;
(2 × 3) + (2 × 4) = 14
This should be the same with the original factored expression; 2(7) = 14
Thus, the method is Once an expression has been factored, use the Distributive Property to expand the expression. The expanded expression should be the original expression.

Why does x^4 * x^-4 = 1?
Answer:
Step-by-step explanation:
when you have a negative exponent, you are going to have a fraction. Example: 2^4 * 2^-4= 2^4 is 16 2^-4 is 1/16.
You get the 16 but because it was a negative exponent, the 16 goes on the bottom. 16 as a fraction is 16/1.
When you multiply 16/1 and 1/16. It comes up to 16/16 or 1.
Does this help?
Answer:
below
Step-by-step explanation:
We can use the product rule of exponents to solve [ x^y * x^z = x^y+z ].
x^4 * x^-4 = 1
x^4+(-4) = 1
x^0 = 1
1 = 1
