A.
[tex]((1/4)^{-3})^{-2} = (1/4)^{(-3)*(-2)}=(1/4)^6<1[/tex]So it is less than 1
B.
We can change -3 to 3 or -2 to 2.
This will result in:
[tex](1/4)^{-6}=4^6 >1[/tex](a) The value of given expression "((1/4)⁻³)⁻²" is less than 1, and (b) To make value greater than 1, change second exponent to positive; to make it equal to 1, change first exponent to 0.
Part (a) : Starting from the innermost exponent, (1/4)⁻³ simplifies to 4³, which is 64.
So, ((1/4)⁻³)⁻² becomes (64)⁻², which is 1/4096. Since 1/4096 is less than 1, the value of the expression is less than 1.
Part (b) : To change the value to greater than 1:
Change the second exponent to a positive value, making it ((1/4)⁻³)²,
This simplifies to (4³)², which is 4096.
To change the value to equal 1:
Change the first exponent to 0, making it ((1/4)⁰)⁻². This simplifies to (1)⁻², which is 1.

Dilate Triangle ABC so it's scale factor is 3 and the center of dilation is the origin.
A(1,1)
B(3,1)
C(2,3)
Step-by-step explanation:
Dilation :
the scale factor is 3 and the center of dilation is the origin.
A(1,1) => A'(3, 3)
B(3,1) => B'(9, 3)
C(2,3) => C'(6,9)
The transformations A(1,1) → A'(3, 3), B(3,1)→ B'(9, 3), and C(2,3) → C'(6,9) represents a dilation centered at the origin.
What is a transformation?On the coordinate plane, you may dilate figures. The origin is frequently utilized as the center of dilatation. If you are distorting a figure centered at the origin, you may find the points in the image by multiplying the coordinates of the points in the preimage by the scale factor.
As per the given question,
We have the scale factor i.e. 3 multiplying the coordinates of the points (x, y) for the center of dilation is the origin.
A(1,1) → A'(3, 3)
B(3,1)→ B'(9, 3)
C(2,3) → C'(6,9)
Thus, the transformations A(1,1) → A'(3, 3), B(3,1)→ B'(9, 3), and C(2,3) → C'(6,9) represents a dilation centered at the origin.

what is the answer to 2/5+5/10=
Answer:
[tex]\frac{2}{5\\}[/tex] + [tex]\frac{5}{10}[/tex]= [tex]\frac{9}{10}[/tex]
Step-by-step explanation:
Because this is not multiplication or diving you must find the same denominator, which is 10. Now, because 5/10 is already 10 I don't need to change that, but if you see that 2/5 does not have the denominator of 10. Then, I need to multiply 2 on the numerator and the denominator because 5(2) equals 10 and whatever is multiplied to the denominator has to be multiplied to the numerator. So. now the numerator is 4. Lastly, what you need to do is add them together. So, (2+5)=7 and the denominator is stays as 10 because it is addition. So, our final answer is 9/10

I find a graphing calculator shows the zeros of higher-degree polynomials easily. The function graph is attached.
For the purpose here, the vertical scale factor π/3 can be eliminated, as it does not change the values of the zeros. That is, the polynomial we need to solve is x²(x -15) +275 = 0.
It turns out that a reasonable iterator for finding a solution is x' = √(275/(15 -x)). x = 5 is a reasonable starting point. The iterator is what you get by solving for the x outside the parentheses in the above cubic equation.

Because all the angles of a triangle sum to [tex]180^{\circ}[/tex], we have that [tex]p+54+90=180[/tex].
We combine like terms on the left side to get [tex]p+144=180[/tex].

( Type an equation )
Please Help asap
Step-by-step explanation:
a. Substituting (0,b) into the point-slope form, we get y = mx + b. Plug in 0 to the x1 value and plug in b into the y1 value. Add b to both sides and you should get y = mx+b.
b. Slope-intercept shows how to get specific x or y values at a point if three of the four variables (y, m, x, or b) are known. Point slope form is used mainly when finding the slope from two distinct points. (Later, you'll learn it's importance in the definition of a derivative :).)
c. y = mx + b. Refer to a.

a) y-b=m(x-0)

Zayn puts garland around a square window. He uses 888 meters of garland.
What is the height of the window?
Answer:
222 meters
Step-by-step explanation:
Zayn puts a total of 888 meters of garland around a square window.
Because a square has all equal sides, divide the amount of garland he used by 4 to find how much is used per side:
888 ÷ 4 = 222
So, the height of the window is 222 meters.

fish is 35 cm.
Thirty fish are taken from Lake B and the mean length of the
fish is 42 cm.
Calculate the mean length of the 100 fish.
Answer:
So, 100 fish taken from Lake A would have a mean length of 50 cm and 100 fish taken from Lake B would have a mean length of 140 cm
Step-by-step explanation:
1 fish from Lake A would be 0.5 cm long you calculate that by dividing 70 from 35 and you calculate the fish from Lake B by dividing 30 from 42 which would be 1.4 cm, (english is not my first language so I hope you understood everything :D)
