Answer:
y = -3/8(x - 4)² + 7 or y = -3/8x² + 6x + 1Step-by-step explanation:
We can see on the graph that the vertex is (4, 7) and the leading coefficient is negative as parabola opens down.
The vertex form is:
y = a(x - h)² + k, substitute coordinates to get,y = a(x - 4)² + 7Considering the y-intercept is (0, 1), substitute values to find the value of a:
1 = a(0 - 4)² + 7a(4²) = 1 - 716a = -6a = -6/16a = -8/3The function is:
y = -3/8(x - 4)² + 7In standard form:
y = -3/8(x² - 16x + 16) + 7 = -3/8x² + 6x - 6 + 7 = -3/8x² + 6x + 1Related Questions

Solve the equation below. Simplify if necessary.
-4/7v = -8 2/3
Show how you did it please :)
Answers
Answer:
15 1/6
Step-by-step explanation:
change -8 2/3 into an improper fraction = -26/3
-4/7v = -26/3
cross-multiply:
3(-4v) = (-26)7
-12v = -182
v = 182/12
v = 15 1/6
the perimeter of a rectangular court is 224 feet. The length is 4 feet more than the width. Write and solve an equation to find the dimension of the court.
Answers
L=4+x
W= x
224 = 2(4+x) + 2x
224 = 8+2x+2x
216 = 4x
54 = x
Plugging x = 54 into initial dimensions:
L = 54 + 4 = 58
W = 54
In your own words, what is a radical expression?
Answers
Answer:
In mathematics, a radical expression is defined as any expression containing a radical (√) symbol. Many people mistakenly call this a 'square root' symbol, and many times it is used to determine the square root of a number. However, it can also be used to describe a cube root, a fourth root, or higher. When the radical symbol is used to denote any root other than a square root, there will be a superscript number in the 'V'-shaped part of the symbol. For example, 3√(8) means to find the cube root of 8. If there is no superscript number, the radical expression is calling for the square root.
The term underneath the radical symbol is called the radicand.

Step-by-step explanation:
Looking at the chart, week 22 would be between the week 20 and week 25 marks. As a result, the weight should be between 275 and 425 pounds. As a result, A is out. Week 22 will be bigger than week 20 (275), so B is also out. Week 22 is in between Week 20 and 25, so it isn't bigger than Week 25's pumpkin; D is out for this reason. That leaves C, 350 pounds, as our answer.

Cosx=4/5 what is sin2x cos2x and tan2x
Answers
Answer:
-24/5
Step-by-step explanation:
The solution to the problem is as follows:
cscx < 0 means 1/sinx < 0, or sinx < 0.
sinx = -3/5 because you're dealing with a 3-4-5 triangle, and we established
sinx is negative.
sin2x = 2sinxcosx = 2*-3/5*4/5 = -24/25
cos(2x) = cos^2(x) - sin^2(x) = 16/25 - 9/25 = 5/25 = 1/5
tan2x = sin2x / cos2x = -24/5
