what is the square root of 1/64
The square root of 1/64 is 1/8.
To find the square root of 1/64, we can simplify the fraction first by taking the square root of both the numerator and the denominator separately.
The square root of 1 is 1,
and the square root of 64 is 8:
So, √(1/64)
= √1 / √64
= 1/8
Therefore, the square root of 1/64 is 1/8.

which products result in difference of squares
(x-y)(y-x)
(6-y)(6-y)
(3+xz)(-3+xz)
(y^2-xy)(y^2+xy)
Answer:
[tex](3+xz)(-3+xz)[/tex]
[tex](y^2-xy)(y^2+xy)[/tex]
Step-by-step explanation:
The Difference of Squares
Any difference of two squared monomial results in a factored form like shown below:
[tex]a^2-b^2=(a-b)(a+b)[/tex]
Similarly:
[tex](a-b)(a+b)=a^2-b^2[/tex]
For a product of binomials to be a difference of squares, they must be in the described form.
------------------------
(x-y)(y-x) can be rewritten as:
-(x-y)(x-y)
Since both binomials are identicals, the product will not result in a difference of squares.
-----------------------
(6-y)(6-Y)
Since both binomials are identicals, the product will not result in a difference of squares.
-----------------------
(3+xz)(-3+xz) can be rewritten as:
(xz+3)(xz-3). This product is a sum multiplied by a difference of the very same terms, thus the result is a difference of squares:
[tex](3+xz)(-3+xz)=(xz)^2-9[/tex]
-----------------------
[tex](y^2-xy)(y^2+xy)[/tex]. This product is a sum multiplied by a difference of the very same terms, thus the result is a difference of squares:
[tex](y^2-xy)(y^2+xy)=y^4-(xy)^2[/tex]
-----------------------
Summarizing:
(3+xz)(-3+xz)
[tex](y^2-xy)(y^2+xy)[/tex]

A line perpendicular to QR is given by the equation 5x + 2y = 9
Find an expression for b in terms of a. W
Answer:
b= (2a+11)/5
Step-by-step explanation:
5x + 2y = 9
2y=9-5x
y= 9/2 - 5x/2
slope, m1= -5/2
for perpendicularity, m1 × m2 = -1
slope for QR= m2=
[tex] = - 1 \div \frac{ - 5}{2} = - 1 \times \frac{2}{ - 5} = \frac{ - 2}{ - 5} = \frac{2}{5} [/tex]
m2 is 2/5
[tex]qr = \frac{b - 3}{a - 2} [/tex]
[tex] \frac{2}{5} = \frac{b - 3}{a - 2} [/tex]
5(b-3)=2(a-2)
5b-15=2a-4
5b=2a-4+15
5b= 2a+11
[tex]b = \frac{2a + 11}{5} [/tex]
An expression for b in terms of a is b = (2a + 11)/5.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
Given an equation of a line 5x + 2y = 9 ⇒ 2y = - 5x + 9 ⇒ y = (-5/2)x + 9/2.
So, the slope of the line parallel to QR is the slope negative reciprocal of (-5/2) which is (2/5).
We know slope m = (b - 3)/(a - 2).
∴ (2/5) = (b - 3).(a - 2).
2(a - 2) = 5(b - 3).
2a - 4 = 5b - 15.
2a + 11 = 5b.
b = (2a + 11)/5.

- ABC = DEF
- ABC = FED
Answer:
I’m pretty sure it’s Triangle ABC is congruent to Triangle DEF.
Step-by-step explanation:
If you rotate Triangle DEF to where the 90 degree angle is on the bottom right, you can the compare the two triangles. You can divide 300/25, 240/20, and 180/15. They all result in 12 meaning they are congruent and similar in that way. (I’m only 90% this is right btw)

chris worked 3 1/2 hours at his uncles farm. He was paid 8$ for every 1/4 hour he worked. How much money did chris make
Answer:
$112
Step-by-step explanation:
So first figure out how much he makes an hour
8*4 is 32.
32*3 1/2 is $112
The amount that Chris will make will then be $112.
The first thing to do is to divide 3 1/2 by 1/4. This will be:
= 3 1/2 / 1/4
= 7/2 × 4/1
= 14
Now we'll then multiply 14 by $8. This will be:
= $8 × 14
= $112
The amount made will be $112.

The line L is a tangent to the circle x2 + y2 = 45 at the point (-3, 6).
The line L crosses the x-axis at the point P.
Work out the coordinates of P.
Answer:
The point P is (-15,0).
Step-by-step explanation:
We need to find the slope of the line L to get the coordinates of P.
We know that L is tangent to the circle at point (-3, 6), which means L is perpendicular to the radius of the circle (a line between the origin (0,0) and the tangent point (-3,6))
So let's find the slope or the radius.
[tex]m_{R}=\frac{6-0}{-3-0}[/tex]
[tex]m_{R}=-2[/tex]
Now, we know that if two lines are perpendiculars their slopes follow the rule:
[tex]m_{L}=-\frac{1}{m_{R}}[/tex]
[tex]m_{L}=\frac{1}{2}[/tex]
Knowing the slope of L we can find the equation of this line. The slope-intercept equation of a line is:
[tex]y=mx+b[/tex]
[tex]y=\frac{1}{2}x+b[/tex]
Using the point (-3,6) we can find b.
[tex]6=\frac{1}{2}(-3)+b[/tex]
[tex]b=\frac{15}{2}[/tex]
The line equation will be:
[tex]y=\frac{1}{2}x+\frac{15}{2}[/tex]
The point P has only an x-coordinate value (x,0)
So we have:
[tex]0=\frac{1}{2}x+\frac{15}{2}[/tex]
[tex]x=-15[/tex]
Therefore, the point P is (-15,0).

Ashton just launched a new business page on social media. After one month, she has 35 followers.
She decides to take a course that promises to triple her number of followers each month for 6
months. After 7 months, how many followers will Ashton have if this is true?
Answer:
122.5
Step-by-step explanation:
If it triples her followers per 6 months then it gives her half of her followers in one month. So 35 times 3.5 which is 122.5
After [tex]7[/tex] months, Ashton will have [tex]25,515[/tex] followers.
What is modelling ?Modelling is the process of creating a mathematical representation of a real-world scenario to make a prediction or provide insight.
We have,
Number of followers [tex]=35[/tex]
So, Every month increase is triple i.e. [tex]3[/tex] times for next [tex]6[/tex] months.
So,
According to the question,
Every month increase [tex]=\ 3\ *\ Current\ Follower[/tex]
So,
Followers after [tex]7[/tex] months [tex]= 35*(3)^6[/tex]
Because followers are increasing at the rate of three times per month,
So,
Followers after [tex]7[/tex] months [tex]= 35*(3)^6=25,515[/tex]
Hence, we can say that After [tex]7[/tex] months, Ashton will have [tex]25,515[/tex] followers.

A textbook store sold a combined total of 435 psychology and sociology textbooks in a week. The number of sociology textbooks sold was 61 less than the number of psychology textbooks sold. How many textbooks of each type were sold?
Answer:
248 psych books, 187 soc books.
Step-by-step explanation:
x psych books were sold
x-61 soc books were sold
Total books was 435.
So -
x+x-61 = 435
2x-61 = 435
2x = 496
x = 248.
so x-61 = 187 and
248+187 = 435.
248 psych books, 187 soc books.
