Answer:
The y-intercept for this equation is 22.
Step-by-step explanation:
You can solve this quite easily by assigning a zero value to x and solving for y. That is where the curve will intersect the x-axis:
y = 2(x - 3)² + 4
y = 2(x² - 6x + 9) + 4
y = 2x² - 12x + 18 + 4
y = 2x² - 12x + 22
EDIT
Note that the expression above is in standard form, though it can also be factored if needed:
y = 2(x² - 6x + 11)
Now we can solve for an x value of zero:
y = 2(0)² - 12(0) + 22
y = 22
So the y-intercept is 22.

Step-by-step explanation:
Solve x4 - 11x2 + 18 = 0.
Answer:
x=√2, x=-√2, x= 3 and x=-3
Step-by-step explanation:
We need to solve the equation x^4 - 11x^2+18=0
We can replace x^4 = u^2 and x^2 = u
So, the equation will become
u^2 -11u+18 = 0
Factorizing the above equation:
u^2 -9u-2u+18 =0
u(u-9)-2(u-9)=0
(u-2)(u-9)=0
u=2, u=9
As, u = x^2, Putting back the value:
x^2 =2 , x^2 =9
taking square roots:
√x^2 =√2 ,√x^2=√9
x=±√2 , x = ±3
so, x=√2, x=-√2, x= 3 and x=-3

If f(x)= x/2-2 and g(x)= 2x^2+x-3, find (f+g)(x).
Answer:
2x^{2} + \frac{3}{2} x - 5
Step-by-step explanation:
(f+g)(x) = f(x)+g(x)
(f+g)(x)= [tex]\frac{x}{2} -2[/tex] + [tex]2x^{2} +x-3[/tex] = [tex]2x^{2} + \frac{3}{2} x - 5[/tex]

Describe the cross section formed by the plane and the sphere.
9514 1404 393
Answer:
circle of radius 27 inches
Step-by-step explanation:
Anywhere a plane cuts a sphere, the cross section is a circle. When the plane includes the center of the sphere, the circle has the same radius the sphere has.
The cross section is a circle of radius 27 inches.
X^9/7 convert from exponent form to radical form
Answer:
[tex]x^{\frac{9}{7}} = \sqrt[7]{x^9}[/tex]
Step-by-step explanation:
You can solve this by realising that the denominator of a fractional exponent can be expressed as the base of a radical.
Note also that the order does not matter. You could also express it as
[tex]\sqrt[7]{x}^9[/tex]
The reason this works is that you're effectively breaking the exponent into fractions. The first answer is the equivalent of:
[tex](x^9)^{1/7}[/tex]
and the second would be:
[tex](x^{1/7})^9[/tex]
In both cases, the exponents would be multiplied, giving the same result.

Answer:
The country's population decreased about 5.8 % during this time period.
Step-by-step explanation:
Population in 1990 = 164 million
Population in 2010 = 155 million
Determine the percent decrease
The formula used is: [tex]Percent\:Decrease=\frac{Initial\:Value-New\:Value}{New\:Value}\times 100[/tex]
We have :
Initial Value = 164 million (164,000,000)
New Value = 155 million (155,000,000)
Finding percent decrease
[tex]Percent\:Decrease=\frac{Initial\:Value-New\:Value}{New\:Value}\times 100\\Percent\:Decrease=\frac{164,000,000-155,000,000}{155,000,000}\times 100\\Percent\:Decrease=\frac{9,000,000}{155,000,000}\times 100\\Percent\:Decrease=5.8\%[/tex]
So, The country's population decreased about 5.8 % during this time period.

Find an equation of the line having the given slope and containing the given point.
m= -6, (5,9)
The equation of the line is y =
(Simplify your answer. Type your answer in slope-intercept form. Use integers or fractions for any numbers in the expression.)
Answer:
[tex]y = -6x + 39[/tex]
Step-by-step explanation:
The equation of a line has the following format:
[tex]y = mx + b[/tex]
In which m is the slope and b is the y-intercept(value of x when y = 0).
We have that the slope is m = -6:
So [tex]y = -6x + b[/tex]
Contains point (5,9):
This means that when [tex]x = 5, y = 9[/tex]. We replace this into the equation to find b. So
[tex]y = -6x + b[/tex]
[tex]9 = -6(5) + b[/tex]
[tex]b = 39[/tex]
So
[tex]y = -6x + 39[/tex]
Freddie has a bag of jelly beans that has the following colours. 2 purple 1 red 4 yellow 3 orange. What is the probability that Freddie will select an orange jelly bean?\ 10% 20% 30% 40%
100 point
Answer:
30%
Step-by-step explanation:
3 out of the ten beans are orange
3/10=30%
Answer:
The answer is 30%.
Step-by-step explanation:
There are 2 purple, 1 red, 4 yellow, and 3 orange jelly beans. If you add all those together, you will get 10. So, 3 out of the 10 jelly beans are orange. That is 3/10 in fraction form. 3/10 equals to 30%, so that is your answer.

You play the following game with a friend. You share a pile of chips, and you take turnsremoving between one and four chips from the pile. (In particular, at least one chip must beremoved on each turn.) The game ends when the last chip is removed from the pile; the onewho removes it is the loser.It is your turn, and there are 2014 chips in the pile. How many chips should you remove toguarantee that you win, assuming you then make the best moves until the game is over
Answer:
Each time, a person takes 1, 2, 3, or 4 chips. The strategy for a player to win the game is taking the number of chips so that the number of chips left is the form of 5k + 1 .
If It is my turn, and there are 2014 chips in the pile, I shoud take 3 chips and the left is 2011 (=5.k +1). And if the opponent takes x chips (x = 1, 2, 3, 4) , i win take 5 - x chips to guarantee the left is always in the form 5k + 1. And finally, the opponent will take the last chip.
