Answer:
4) [tex]y=-\frac{1}{3} (x-2)^2-3[/tex] 7) [tex]2x^2+12x+18[/tex]
5) [tex](-2,-3)[/tex] 8) [tex](0,-3)[/tex]
Step-by-step explanation:
7) Add [tex]2y^2[/tex] to both sides of the equation.
[tex]x-12y-18=2y^2[/tex]
Add 12y to both sides of the equation.
[tex]x-18=2y^2+12y[/tex]
Add 18 to both sides of the equation.
[tex]x=2y^2+12y+18[/tex]
Use the form of [tex]ax^{2} +bx+c[/tex] to find the values of a, b, and c.
a = 2, b = 12, c = 18
Substitute the values of a and b into the formula [tex]d=\frac{b}{2a}[/tex]
[tex]d=\frac{12}{2(2)}[/tex]
Simplify the bottom.
d = 3
Find the value of e using the formula e = [tex]c-\frac{b^2}{4a}[/tex]
Raise 12 to the power of 2
[tex]e=18-\frac{144}{4(2)}[/tex]
Multiply 4 by 2.
[tex]e=18-\frac{144}{8}[/tex]
Divide 144 by 8.
[tex]e=18-1[/tex] · 18
Multiply [tex]-1[/tex] by 8.
[tex]e = 18-18[/tex]
Subtract 18 from 18.
e = 0
Substitute the values of a, d, and e into the vertex form [tex]a(x+d)^2+e[/tex].
[tex]2(y+3)^2+0[/tex]
Set x equal to the new right side.
[tex]x=2(y+3)^2+0[/tex]
Use the vertex form, [tex]x=a(y-k)^2+h[/tex], to determine the values of a h & k.
a = 2
h = 0
k = [tex]-3[/tex]
Find the vertex [tex](h,k)[/tex]
[tex](0,-3)[/tex]

Gió thổi trên mặt nước trong các đại dương chịu trách nhiệm cho dòng hải lưu. Tuy nhiên, dòng hải lưu trong đại dương không được hình thành bởi gió đơn thuần. Nước gần cực lạnh trong khi nước gần xích đạo ấm. Sự chênh lệch nhiệt độ giữa hai vùng nước này cũng chịu trách nhiệm cho sự hình thành dòng hải lưu. Địa hình đáy đại dương, mưa và thậm chí thủy triều cũng gây ra dòng chảy trong nước.

How are prisms and pyramids alike and how are they different?
Prisms and pyramids are geometric shapes that have flat sides, flat bases and angles. So those are some similarities. However, the bases and side faces on prisms and pyramids differ. Prisms have two bases while pyramids only have one. There are a variety of pyramids and prisms, so not all shapes in each category look the same.

Doug needs to order 25,000 g of a
supplement. At the store,
supplements come in 5 kg packages
that cost $80 each. What will Doug's
order cost?
Answer:
$2000
Step-by-step explanation:
1,000 g would be = 1 Kg so it would be 25 Kg
And 25 X 80 = 2000
Answer:
$400
Step-by-step explanation:
25,000 grams is equal to 25 kg, so if 5 kg equals $80, the total 25 kg divided by 5 equals five. With this you multiply; 5 × 80 kg = 400. So $400 is the answer.

Answer:
7.1
Step-by-step explanation:
Use the trig ratio tan to find b
4.5 x tan (23) = b = 7.14668887526
7.1
Answer:
b ≈ 1.9
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan23° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{b}{4.5}[/tex] ( multiply both sides by 4.5 )
4.5 × tan23° = b , then
b ≈ 1.9 ( to the nearest tenth )

Nelda baked two kinds of pasta in pans. Each pan was the same size. She sliced one pan of pasta into 4 equal pieces. She sliced the other pan into 6 equal pieces. How can the pans of pasta now be sliced so that both pans have the same-sized pieces? If Nelda has served 8 pieces from 1 pan so far, what fraction of 1 pan has she served?
Answer:
6 equal parts; 8 equal parts
Both those will go into 24.
Step-by-step explanation: Each of six slices of the first pasta has the area 1%2F6 of the entire pan.
Each of eight slices of the second pasta has the area 1%2F8 of the original pan.
Nelda will cut each 1%2F6 in 4 equal pieces to get 1%2F24.
She also will cut each 1%2F8 in 3 equal pieces to get 1%2F24.
solve the equation by completing the square. Round to the nearest hundredth if necessary.

_____ + 15 − 15 = 21
help mee
Answer:
x = 21
Step-by-step explanation:
x + 15 - 15 = 21
+ 15 and - 15 cancel out
So x = 21
Let's solve the longer way
x + 15 - 15 = 21
x + 15 = 21 + 15 . (adding 15 to both sides)
x = 21 (Subtracting 15 from both sides)

Answer:
a) see attached
b) 1/3
Step-by-step explanation:
Your grid doesn't come with any coordinate axes, so you will need to draw those and label them. You will also need to determine the number of grid squares for each unit. (I suggest 2 grid squares per unit to give you a little more distance between the points you plot. The attachment shows 5 small squares per unit. You may not have this much space on your graph.)
Plot the points. Once you do this, you can see that their horizontal difference is 3 units and their vertical difference is 1 unit. The right point is above the left point, so the slope is positive:
m = (rise)/(run) = 1/3 . . . slope of the line

The hardest part about negative numbers in addition is remembering when to add, rather than subtract. In the last equation, we add the numbers together, because the negative sign cancels out with subtraction. All of the other equations we can follow exactly what it says to do, because there are no minus signs right next to each other.

Step-by-step explanation:
Function A is the only one with a positive y-intercept
so it's the greatest
Function B has a y-intercept of -1 as read of the graph
it is the middle one
Function C has a y-intercept of -9/4 as given in point (0, -9/4)

A particle is moving with acceleration a ( t ) = 18 t + 16 . Its position at time t = 0 is s ( 0 ) = 10 and its velocity at time t = 0 is v ( 0 ) = 16 . What is its position at time t = 8 ?
Answer:
[tex]s(8)=2186[/tex]
Step-by-step explanation:
A particle is moving with acceleration modeled by the function:
[tex]a(t)=18t+16[/tex]
We are given that its position s(t) at t = 0 is 10 and that its velocity v(t) at t = 0 is 16.
And we want to find its position at t = 8.
Velocity is the integral of the acceleration. Hence:
[tex]\displaystyle v(t)=\int a(t)\, dt=\int 18t+16\, dt[/tex]
Find the velocity. Remember the constant of integration!
[tex]v(t)=9t^2+16t+C[/tex]
Since v(t) is 16 when t = 0:
[tex](16)=9(0)^2+16(0)+C\Rightarrow C=16[/tex]
Hence, our velocity is given by:
[tex]v(t)=9t^2+16t+16[/tex]
Position is the integral of the velocity. Hence:
[tex]\displaystyle s(t)=\int v(t)\, dt=\int 9t^2+16t+16\, dt[/tex]
Integrate:
[tex]\displaystyle s(t)=3t^3+8t^2+16t+C[/tex]
s(t) is 10 when t = 10. Hence:
[tex]C=10[/tex]
So, our position function is:
[tex]s(t)=3t^3+8t^2+16t+10[/tex]
The position at t = 8 will be:
[tex]s(8)=3(8)^3+8(8)^2+16(8)+10=2186[/tex]
