Answer:
third option
Step-by-step explanation:
Given that x = - 2 + [tex]\sqrt{8}[/tex] is a root
Complex roots always occur as conjugate pairs , thus
x = - 2 + [tex]\sqrt{8}[/tex] is a root then x = - 2 - [tex]\sqrt{8}[/tex] is a root
The required factor is then
(x - (- 2 - [tex]\sqrt{8}[/tex] ) )

A is directly proportional to the square root of B
When A = 50, B+4 . Find A in terms of B
Answer:
A=50, B=4
A is directly proportional to the square root of B
name the constant 'k'
A = k*B^0.5
50 = k*4^0.5
50=2k
k=25
=> A =25 root B
i.e, A = 25*B^0.5 (The answer should be written the way it is written in the attached picture)
A written in terms of B is 25√B.
What is direct and inverse proportion ?In direct proportion if one quantity increases the other quantity also increases and vice versa.In case of inverse proportion when one quantity increases the other quantity decreases and vice versa.
According to the given question A is directly proportional to the square root of B.
∴ A = K[tex]\sqrt{B}[/tex]
Given when A = 50 B = 4.
50 = K[tex]\sqrt{4}[/tex]
50 = 2k
k = 25.
So, A =25√B.

The circumference of a circular garden is 75.36 feet. What is the radius of the garden
Answer:
12 rounded to a whole number.
Step-by-step explanation:
75.36 divided by pi (3.14159) = 23.987. this is diameter (the length from one side of a circle to the other).
but we need to find the radius. the radius is half way across a circle.
23.987 divided by 2 = 11.993.
round this to a significant whole number and you get 12.
The radius of the garden is,
⇒ r = 12
We have to given that;
The circumference of a circular garden is,
⇒ C = 75.36 feet.
Since, We know that;
The circumference of a circle is,
⇒ C = 2πr
Substitute given values,
⇒ 75.36 = 2 × 3.14 × r
⇒ 75.36 = 6.28 r
⇒ r = 12
Thus, the radius of the garden is,
⇒ r = 12

Jenny and her children went to the SeaWorld.She purchased adult ticket for herself and children tickets for her 2 boys. Tickets cost $39.99 for one adult and $19.99 for each child. Let x represent the number of adult ticket purchase and y represent the number of child tickets purchase. Write an expression to represent the total cost of the tickets Jenny purchased
Given:
She purchased adult ticket for herself and children tickets for her 2 boys.
Cost of one adult ticket = $39.99
Cost of one child ticket = $19.99
To find:
The expression to represent the total cost of the tickets Jenny purchased.
Solution:
Let x represent the number of adult ticket purchase
and y represent the number of child tickets purchase.
Cost of one adult ticket = $39.99
Cost of one child ticket = $19.99
Total cost = 39.99x + 19.99y
Therefore, the expression for total cost is 39.99x + 19.99y.
She purchased one adult ticket and 2 child tickets.
Substitute x=1 and y=2 in the above expression.
Total cost = 39.99(1) + 19.99(2)
= 39.99 + 39.98
= 79.97
Therefore, the required expression to represent the total cost of the tickets Jenny purchased is 39.99(1) + 19.99(2) and total cost is $79.97.
A man throws a 0.2 N metal ball vertically into the air and observes that after it has traveled upward 2.0 m, it is traveling at 5 m/s. Use the work–energy principle to calculate how much further the ball will continue to travel upward.
1.27 m is the correct answer.
Find the slope of the line: y = -5x - 1
A
m = -5/1
B
m = -1/5
Answer:
Slope: -5/1
Step-by-step explanation:
The slope is always the coefficient of x in y=mx+b, so m is -5 (you don't reverse it)
Answer: A) m = -5/1
Step-by-step explanation: The format of slope intercept form is y=mx+b , therefore M= -5/1.

t + (-8) + 13 = 43
Answer:
T=38
Step-by-step explanation:
t−8+13=43
Step 1: Simplify both sides of the equation.
t−8+13=43
t+−8+13=43
(t)+(−8+13)=43(Combine Like Terms)
t+5=43
t+5=43
Step 2: Subtract 5 from both sides.
t+5−5=43−5
t=38
Answer:
t= 38
Step-by-step explanation:
t+(-8)+13=43
t-8+13=43
t=43-13+8
t=30+8

When the number of bricks is multiplied by 2, the length is multiplied by
1.
2.
3.
6.
Answer:
The length will be multiplied by 2.
Step-by-step explanation:
By looking at the first and third ratio, we know that the no. of birck have been multiplied by 2 and the length has also been multiplied by 2 .
So when the number of bricks is multiplied by 2, the length is multiplied by 2
Answer:
2Step-by-step explanation:
Using the table we observe the points
(6, 3) and (12, 6)The number of bricks doubled
6*2 = 12, andThe length is doubled accordingly
3*2 = 6So the answer is 2

The point G (-6, 4) is translated 2 units left.
What are the coordinates of the resulting point G'?
A (-8,4)
B) (-6,2
C (-4,4)
(-8,6)
Answer:
A
Step-by-step explanation:
By translating 2 units left, it means the x-axis value is made more negative by 2 units
So we are going to subtract two from the x-coordinate
So we have;
(-6-2,4)
= (-8,4)

how many quarters make 40 dollars
can you work it out with quarters
help me please help me please help me please
Given problem;
Number of quarters in $40;
To solve this problem;
Convert the dollar value to cents;100cents = $1
In $40, we would have; 40 x 100 = 4000cents
1 quarter = 25 centsSo, divide 4000cents by 25 to obtain the number of quarters in that amount of dollars;
Number of quarters = [tex]\frac{4000}{25}[/tex] = 160
So there are 160 quarters in $40

Find the slope and write an equation of the line which passes through the points. (−3, 9) and (−3, −5)
Answer:
Slope: undefined
Equation: x=-3
Step-by-step explanation:
To find the line that passes through the points, you first want to find the slope. The formula for slope is [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]. Once we have the slope, we can use any given point to plug in to find the y-intercept.
[tex]m=\frac{-5-9}{-3-(-3)} =\frac{-14}{0}[/tex]
We can see that the slope is undefined. If we look at the point, we notice that they both have the same x-coordinate. This let's us know that the equation is x=-3.
