The one that is in vertex form is
x^2-4x+4
Is each a circle or are they going to be triangles because if so you would divide 5 by 2 and get your answer of 2.5 as the diameter for each slice but if it is circles you would divide 5/7 and get .71428......
Answer:
The price of a burger is $4 and that of cone is $1.
Step-by-step explanation:
Let the cost of burger is x and that of cone is y.
ATQ,
3x+5y = 17 ....(1)
And
6x + 9y = 33 ...(2)
Multiply equation (1) by 2.
6x + 10 y = 34 ...(3)
Subtract equation (2) from (3)
6x + 10 y-(6x + 9y) = 34 - 33
6x + 10 y-6x- 9y = 1
y = 1
Put the value of y in equation (1)
3x+5 = 17
3x = 12
x = 4
So, the price of a burger is $4 and that of the cone is $1.
I see y = 3x^2 - 2. If that is the case, there is no movement indicated in the x direction at all, only the y direction. If there was movement along the x axis, there would be a number inside a set of () with the x, like this: (x-3)^2. But that is not there in your case, so the x coordinate of the vertex stays right where it starts, at the origin, or x = 0. The "minus 2" indicates y movement: down 2 units. So the vertex sits at (0, -2). The axis of symmetry is the same as what the x coordinate is, but in equation form. So the axis of symmetry has an equation of x = 0.
Answer:
$1600 invested in 9% fund
$700 invested in 4% fund
Step-by-step explanation:
Let
amount invested in 9% account be "x"
so
amount invested in 4% account would be "2300 - x"
The profit from the account would be the percentage (in decimal) multiplied with the amount invested in that account. So,
<u>Profit in 9% account:</u>
9% = 9/100 = 0.09
0.09 * x
0.09x
<u>Profit in 4% account:</u>
4% = 4/100 = 0.04
0.04(2300-x)
92 - 0.04x
Total profit = 0.09x + 92 - 0.04x
This is equal to 172. We equate this and find x:
Now,
2300 - x = 2300 - 1600 = 700
Hence,
$1600 invested in 9% fund
$700 invested in 4% fund
