A parabola has a minimum value of 0, a y-intercept of 4, and an axis of symmetry at x = -2

1 answer:

3 0

Since the minimum value is 0 and axis of symmetry is -2 this means that the vertex is at -2,0 now with the y intercept of 4. You can now plug the values into Vertex form which will be y=a(x-h)^2+k. a being the shrink or stretch of the parabola, h being the x value of the vertex, and k being the y value of the vertex. with all of that plugged in it should look like y=(x+2)^2. You can check this equation by plugging in 0 as x which should find the y intercept of 4. So it should then look like y=(0+2)^2 -> y=(2)^2 -> y=4

Please help me to solve this sum<br>please gI've correct answer

disa [49]

This question requires creating a few equations and working through them step-by-step. Now, first let's give each of the shapes a variable: let's say that the blue shape is a, the orange shape is b and the green shape is c.

1. We can technically create six formulas for the magic square, with three for sum of the rows and three for the sum of the columns, however the smartest way to approach this is to observe whether there are any obvious answers that we can get.

We can see in row 2 that there are three of the same shape (a) that add to 57. This makes it very simple to calculate the value of the shape.

Since 3a = 57

a = 57/3 = 19

2. Now we need to find a row or column that includes a and one other shape; we could choose either column 2 or 3, so let's go with column 2. Remembering that the blue shape is a and the orange shape is b:

2a + b = 50

Now, given that a = 19:

2(19) + b = 50

38 + b = 50

b = 12

3. We can now take any of the rows or columns that include the third shape (c) since we already know the values of the other two shapes. Let's take column 1:

a + b + c = 38

19 + 12 + c = 38

31 + c = 38

c = 38 - 31

c = 7

Thus, the value of the blue shape is 19, the value of the orange shape is 12 and the value of the green shape is 7.

Answer:

D. 14

Step-by-step explanation:

Point G divides each median into parts that have the ratio ...

short : long = 1 : 2

Then ...

GD : GC = 1 : 2 = 7 : 14 . . . . . . . . multiply the ratio by 7

GC = 14

An Ivy League college accepts 5 students for every 100 that apply. What fraction of applicants is accepted? Write your results i

Law Incorporation [45]

Hello there!

To find the fraction of applicants that are accepted into the Ivy League college, all you have to do is put the number of students accepted (numerator) over the total number of students that apply (denominator). This makes the fraction 5/100. This fraction can be simplified. To simplified, find the GCF of the two numbers. The GCF of 5 and 100 is 5. Divide both parts by 5. 5/100 ÷ 5/5 is 1/20. There. 5/100 is 1/20 in simplest form. The Ivy League college accepts 1/20 of it's applicants.
