(a+b)^2≥4ab
Answers
Mark as brainlist___________________________________
Answer:
(a+b) ²≥4ab explanation below↓↓↓↓
Step-by-step explanation:
We know that
(a-b) ²≥0
a²-2ab+b²≥0
Move -2ab to the other side
a²+b²≥2ab
Add 2ab to both sides
a²+2ab+b²≥4ab
(a+b) ²=a²+2ab+b² therefore :
(a+b) ²≥4ab
A vase in the shape of a cube measures 8 inches on each side. The vase is half full of water. How many cubic inches of water are in the vase?
Answers
Answer:
64in cubes
Step-by-step explanation:
Because if the vase is half full, half of 8 is 4. To find the volume of a cube is l x W x H. So 4 x 4 x 4= 64.
Suppose has a solution. Explain why the solution is unique precisely when has only the trivial solution. Choose the correct answer.
Answers
Answer:
Because [tex]x = y[/tex], then the solution is unique.
Step-by-step explanation:
Given
[tex]Ax = b[/tex]
[tex]Ax=0[/tex]
See comment for complete question
Let there be two solutions x and y.
Such that:
[tex]Ax = b[/tex] and [tex]Ay = b[/tex]
Since:
[tex]Ax = Ay = b[/tex]
Then:
[tex]Ax - Ay = b - b[/tex]
[tex]Ax - Ay = 0[/tex]
This implies that:
[tex]Ax - Ay = A(x-y) = 0[/tex]
The only trivial solution is:
[tex]Ax - Ay = A(x-y) = 0[/tex]
Such that:
[tex]x -y = 0[/tex]
Then
[tex]x = y[/tex]
Because [tex]x = y[/tex], then the solution is unique.

To find:
The simplified answer using only positive exponents.
Solution:
We have,
[tex]\dfrac{10^0r^{-11}s}{3^2}[/tex]
[tex]=\dfrac{(1)r^{-11}s}{9}[/tex]
[tex]=\dfrac{r^{-11}s}{9}[/tex]
Using properties of exponents, we get
[tex]=\dfrac{s}{9r^{11}}[/tex] [tex]\left[\because a^{-n}=\dfrac{1}{a^n}\right][/tex]
Therefore, the required answer is [tex]\dfrac{s}{9r^{11}}[/tex].
The required simplified value is [tex]\frac{s}{9r^{11}}[/tex]
Exponent: Exponent is defined as the method of expressing large numbers in terms of powers.
The given expression is,
[tex]10^0r^{-11}\frac{s}{3^2}[/tex]
The given expression can be simplified as,
[tex]10^0r^{-11}\frac{s}{3^2} =1\times r^{-11}\frac{s}{9} \\=\frac{s}{9r^{11}}[/tex]
So, the simplified value of the given expression is,

What is the unknown of 8/10+____=97/100
Answers
Answer:
17/100
Step-by-step explanation:
The unknown quantity in the given expression is 17/100
What is an expression?Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.
Given is an expression, 8/10 + x = 97/100, we need to find x,
So,
8/10 + x = 97/100
Subtract 8/10 from both the sides,
8/10 + x -8/10 = 97/100-8/10
x = 97/100-8/10
Multiply by 100 both the sides,
100 x = 100(97/100-8/10)
100x = 97-80
100x = 17
Divide the equation by 100
x = 17/100
Hence, the unknown quantity in the given expression is 17/100

A recipe for a fruit drink calls for 2 cups of fruit juice for every 5 cups of water. Look at each drink mix. Does each drink mix follow the recipe?
4 cups of fruit juice and 10 cups of water. Yes. No.
0.5 cup of fruit juice and 1 cup of water. Yes. No.
1 cup of fruit juice and 2.5 cups of water. Yes. No.
7 cups of fruit juice and 17 cups of water. Yes. No.
Answers
2. No
3. Yes
4.no
Answer:
A. Yes
B. No
C. Yes
D. No
Step-by-step explanation:
A and C has an equivalent ratio.
B and D do not.
2:5 x2 = 4:10
Because if we multiply 2 on both the 2 cups of fruit juice and the 5 cups of water we'll get
4:10 which is the ratio of A
If we divide both the 2 cups of fruit juice and the 5 cups of water with 2 we'll get...
2 ÷ 2 = 1
5 ÷ 2 = 2.5
1:2.5 is the ratio for C.
So both C and A are correct
The rest, B and D, are not equivalent.

The line is parallel to y = -3x - 2 and passes through the point (-4, 3)
Answers
Answer:
y = -3x - 9
Step-by-step explanation:
Parallel lines have same slope.
y = mx + b
m -> slope & b ->y-intercept
y = -3x - 2
So, slope of the required line = -3
(-4 , 3)
y - y1 = m(x - x1)
y - 3 = -3(x - [-4])
y - 3 = -3(x + 4)
y - 3 = x*(-3) + 4*(-3)
y - 3 = -3x - 12
y = -3x -12 + 3
y = -3x - 9
