3) The half of (√200 + √128 ) is
1. √100 + √64
2. 9√2
3. 18√2
Answer:
Option 2 i.e. 9√2 is the correct option.
Step-by-step explanation:
Given the expression
[tex](\sqrt{200}\:+\:\sqrt{128})[/tex]
The half of [tex](\sqrt{200}\:+\:\sqrt{128})[/tex] can be determined by dividing the expression in half.
Therefore, we need to solve the expression such as
[tex]\frac{\left(\sqrt{200}\:+\:\sqrt{128}\:\right)}{2}[/tex]
as
[tex]\sqrt{200}=\sqrt{100\times 2}=\sqrt{100^2\times \:2}=10\sqrt{2}[/tex]
[tex]\sqrt{128}=\sqrt{64\times 2}=\sqrt{8^2\times \:2}=8\sqrt{2}[/tex]
so the expression becomes
[tex]\frac{\left(\sqrt{200}\:+\:\sqrt{128}\:\right)}{2}=\frac{10\sqrt{2}+8\sqrt{2}}{2}[/tex]
Add similar elements: [tex]10\sqrt{2}+8\sqrt{2}=18\sqrt{2}[/tex]
[tex]=\frac{18\sqrt{2}}{2}[/tex]
Divide the numbers: 18/2 = 9
[tex]=9\sqrt{2}[/tex]
Therefore, we conclude that:
[tex]\frac{\left(\sqrt{200}\:+\:\sqrt{128}\:\right)}{2}=9\sqrt{2}[/tex]
Hence, option 2 i.e. 9√2 is the correct option.

x2 - 6x + 12 = 0
Answer:
x = 3 ± i [tex]\sqrt{3}[/tex]
Step-by-step explanation:
Given
x² - 6x + 12 = 0 ( subtract 12 from both sides )
x² - 6x = - 12
Using the method of completing the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 3)x + 9 = - 12 + 9
(x - 3)² = - 3 ( take the square root of both sides )
x - 3 = ± [tex]\sqrt{-3}[/tex] = ± i [tex]\sqrt{3}[/tex] ( add 3 to both sides )
x = 3 ± i [tex]\sqrt{3}[/tex]

Identify the correct slope and the y-intercept of
3x - 2y = 12
Answer:
The answer is C
Step-by-step explanation:
3x-2y=12
-3x -3x
-2y=-3x+12
y=3/2x-6
slope = 3/2
y-intercept = -6
Answer:
C) m=3/2 and b=-6
Step-by-step explanation:
The easiest way to do this is by converting the equation into slope-intercept form, which is written y=mx+b. So...
3x-2y=12 Subtract 3x from both sides.
-3x -3x
-2y=-3x+12 Divide both sides by -2.
/-2 /-2
y=3/2x-6
The slope (m) is always right next to x, which, in this case, is 3/2.
The y-intercept (b) is the (simplified) regular number in the equation.
So, the correct answer is C) m=3/2 and b=-6.
Hope this helps you out! Have a nice day :3

8x + 2y = 10
X + 9y = 10
Answer:
Yes.
Step-by-step explanation:
[tex]8x + 2y = 10 \\ x + 9y =10 \\ x = 10 - 9y \\ 8(10 - 9y) + 2y = 10 \\ 80 - 72y + 2y = 10 \\ - 70 y = - 70 \\ y = 1 \\ x = 10 - 9y[/tex]

Which polynomial function f(x) has a leading coefficient of 1, roots –4, 2, and 9 with multiplicity 1, and root –5 with multiplicity 3?
Answer:
f(x) = (x + 5)(x + 5)(x + 5)(x + 4)(x - 2)(x - 9)
Step-by-step explanation:
The polynomial function f(x) possessing a key coefficient of 1:
[tex](x+4)(x-2)(x-9)(x+5)^{3}[/tex] = 0
By opening the above equation;
f(x) = (x + 5)(x + 5)(x + 5)(x + 4)(x - 2)(x - 9)
∵ Thus, the above polynomial function makes the coefficient 1 with a multiplicity of 3 for root - 5 and 1 for -4, 2, and 9.

In ΔUVW, w = 9 cm, v = 2.2 cm and ∠V=136°. Find all possible values of ∠W, to the nearest 10th of a degree.
Complete Question
In ΔUVW, w = 9 cm, v = 22 cm and ∠V=136°. Find all possible values of ∠W, to the nearest 10th of a degree.
Answer:
16.5°
Step-by-step explanation:
In ΔUVW, w = 9 cm, v = 22 cm and ∠V=136°. Find all possible values of ∠W, to the nearest 10th of a degree.
We solve using Sine rule formula
a/sin A = b/sin B
We are solving for angle W
∠V=136°
Hence:
22 /sin 136 = 9 /sin W
Cross Multiply
22 × sin W = sin 136 × 9
sin W = sin 136 × 9/22
W = arc sin [sin 136 × 9/2.2]
W = 16.50975°
W = 16.5°
A bakery needs to make 4 batches of bagels before opening in 3 hours. Each batch of bagels takes 2/4 of an hour to make. How many bagel batches can the bakery make before they open
Answer:6
Step-by-step explanation:
Since each batch of bagels takes 2/4 of an hour to make. This means that in one hour, 2 batches would be made.
Therefore, in 3 hours, the number of batches that would be made will then be:
= 2 × 3
= 6
Therefore 6 batches can be made before opening

Answer:
x = - 5, y = - 9
Step-by-step explanation:
Given
x + 9i = - 5 - yi
For the 2 sides to be equal then the coefficients of like terms must be equal.
x = - 5 and 9 = - y ⇒ y = - 9
Answer:
X= Subtract 9 i from both sides of the equation.
Y= Isolate the variable by dividing each side by factors that don't contain the variable.
Answer:
x = − 5 − y i − 9 i
y = x i − 9 + 5 i
Joey wants to earn an A on his report card. So far he has taken 3 exams and has one
more to go. On the first three exams, Joey scored 88%, 92%, and 84%. What does Joey
need to score on the last test to have an average of 90% for the 9 weeks?
Answer:
96%
Step-by-step explanation:
To have an average of 90 for 4 exams, you know that the sum of the scores on all 4 exams would be 90 * 4 = 360. The sum of the first three scores is 88 + 92 + 84 = 264.
The last thing you have to do is 360 - 264 = 96 because then you know the score he has to get is 96 for an average of 90 on all four exams.
A section of land measuring 2 2/5 acres is divided equally among three brothers. How many acres will each brother receive? *
Answer:
12/15 acres of land
Step-by-step explanation:
Total measure of land = 2 2/5acres
Total brothers = 3
Amount of acres each brothers will receive = Total measure of land/Total brother
Amount of acres each brothers will receive = (2 2/5)/3
Amount of acres each brothers will receive = 2 2/5 ÷ 3
Amount of acres each brothers will receive = 12/5 ÷ 3
Amount of acres each brothers will receive = 12/5 * 1/3
Amount of acres each brothers will receive = 12/15
Hence each brother will receive 12/15 acres of land
The height of a vase is 45.7 centimeters when rounded to the nearest tenth of a centimeter. What is the shortest possible height of the vase? Give your answer to 3 decimal places.
Answer:
45.650 centimeters
Step-by-step explanation:
The height of a vase is 45.7 centimeters when rounded to the nearest tenth of a centimeter. What is the shortest possible height of the vase? Give your answer to 3 decimal places
Given that :
Height of vase = 45.7 when rounded to the nearest tenth
The shortest possible height of the vase : will be 45.65, this is because, the subsequent digit (hundredth) after the tenth digit is the figure rounded to give a tenth digit of 7
From the we know that the tenth digit before rounding is 7 - 1 = 6
And smallest possible value the hundredth placed digit could have in other to be rounded to 1 is 5.
To three decimal place, the thousandth placed value could take the least possible value in a digit series, which is 0
Hence, the shortest possible height of the vase = 4.650
what is the domain and range of this and it is a function?
Answer:
Domain: [-8,inf)
Range: [-3,5]
Function: Yes
Step-by-step explanation:
First, this relation is a function because x's never repeat. The domain is every x-value that the graph covers, on this graph x's start at -8, which is included, and then continue forever. So the domain should be written as [-8,inf) because it is from least to greatest and the bracket shows -8 is included. The range is the y-values the graph covers. On this, the highest y is 5, and then the graph flattens at -3, both points are included. So the range must be [-3,5].
