Answer:
y = 1/3(x + 5)^2 - 4
Step-by-step explanation:
The general vertex form is;
y = a(x-h)^2 + k
From the question, (h,k) are the coordinates of the vertex which is (-5,-4)
So we have
y = a(x + 5)^2 -4
So we need to get the leading coefficient
Simply substitute the point it passes through
x = -2 and y = -1
-1 = a(-2 + 5)^2 - 4
-1 = a(3)^2 -4
-1 = 9a -4
9a = 4-1
9a = 3
a = 3/9
a = 1/3
So the equation is;
y = 1/3(x + 5)^2 - 4

I am a 6-digit number one of my 4s is worth 400,000. My 5 is worth 5 [10s]. My other 5 is worth 1/100 as much.My 8 is worth 800.My 2 is worth 2 . My other digit is a 0 what number am I.
Answer:
The question is corrected to get;
405,852
Step-by-step explanation:
The expression of the description when written as follows;
'I am a 6-digit number one of my 4s is worth 400,000. The other 5 is worth 1/100 as much. My 5 is worth 5 (10s). y 8 is worth 800. My 2 is' worth 2. My other digit is a 0 what number am I, we have;
The number of digits in the number = 6
The position of the number 4 = 100,000s, we have;
4xx,xxx
The position of the number 5 is in the 10s position, we have;
4xx,x5x
The other 5 = 50100 = 0.5
Therefore, we have;
4xx,x5x.5
The position of the 8 is the 100s, to give;
4xx,85x.5
The number 2 is in the unit position, therefore, we have;
405,852

What is parabola?A parabola is a U-shaped plane curve in which any point is an equal distance from both a fixed point (known as the focus) and a fixed straight line (known as the directrix). The issue of parabola is intertwined with the topic of conic sections, and all of its principles are discussed here.
In the given figure,
The curve represent the parabola
Since the curve is passing through
(0,9) from the Y axis and touches x axis at infinity
Now we can use hit and trial method to find the exact equation
So we plot the figure one by one
Hence,
we get the correct equation,
y = [tex](1/2)^{x - 3} + 1[/tex]

A dessert recipe calls for 2 1/2 cups of milk and makes 5 servings. How many cups of ilk are needed for 8 servings?
Answer:
4 cups
Step-by-step explanation:
Number of cups of milk for 5 servings = [tex]2\frac{1}{2} =\frac{5}{2}[/tex] cups
First find number of cups of milk for 1 serving.
Number of cups of milk for 1 serving = [tex]\frac{\frac{5}{2} }{5}=\frac{1}{2}[/tex] cup
Now find umber of cups of milk for 8 servings.
Therefore,
Number of cups of milk for 8 servings = [tex]8(\frac{1}{2})=4[/tex] cups

Sasha buys bagels for her garage sale customers she buys all the chocolate chip bagels and half of the plain bagels each bagel cost 2.50 how much does Sasha spend on bagels
The question is incomplete:
Sasha buys bagels for her garage sale customers she buys all the chocolate chip bagels and half of the plain bagels each bagel cost 2.50 how much does Sasha spend on bagels? The table that shows the types of bagels sold at the bagel shop on Friday is attached.
a. $70
b. $20
c. $90
d. $110
Answer:
c. $90
Step-by-step explanation:
First, you need to find the amount of bagels that Sasha purchased. The statement indicates that she buys all the chocolate chip bagels and the table shows that 28 chocolate chips bagels were sold, so that's the amount she purchased of this type of bagels. Also, the statement indicates that she buys half of the plain bagels and the table says that 16 plain bagels were sold, so you have to divide this amount by 2:
16/2=8
Then, you have to add the amount of chocolate chips bagels plus the amount of plain bagels that Sasha purchased:
28+8=36
Now that you know the amount of bagels that Sasha purchased, you have to multiply this for 2.50 that is the price per bagel:
36*2.50=90
According to this, the answer is that Sasha spends $90 on bagels.

The account pays 2.8% compound interest per year.
Work out the value of her investment after 4 years.
Give your answer to the nearest penny.
Answer:
£8934.34
Step-by-step explanation:
[tex]8000 * 1.028^4 = 8934.34[/tex]
rounding to 2dp
if trunctuated at 2dp however, 8934.33
the number is multiplied by 1.028 to the power of four as you go through the equation four times, so it would be the same as
x * n * n * n * n, where it would simplify to x * n^4
A triangle has side lengths of 14 cm and 7 cm. Which could be the value of the third side, 22 cm or 20 cm?
Answer:
Undefined, it can be 20 cm, 22 cm or any value.A triangle has no limitations for any of each three sides.
Step-by-step explanation:
How it works? The triangles have no limits on their sides, but by their angles. Each triangle sums 180 degrees at the inner angles. If you don't have specific values for the angles it is not necessary to get some values for the third side. It could be 1, 2, .... or even 1000.
Find the value of x and justify your answer
Answer:
a.
2x+4x+3x=180 sum of interior angle of the triangle is 180
9x=180
x=180/9=20
b.
x-20+x+10+x-20=180sum of interior angle of the triangle is 180
3x-30=180
3x=180+30
x=210/3=70
c.x+10+x+20+x=180 linear pair
3x+30=180
3x=180-30
x=150/3=50
Answer:
The picture is kinda blurry so I hope I've got it right.
a) x = 20°
b) x = 70°
c) x = 50°
Step-by-step explanation:
a) 2x + 3x + 4x = 180°
9x = 180°
x = 50°
b) (x - 20°) + (x - 20°) + (x + 10°) = 180°
3x - 30° = 180°
3x = 210°
x = 70°
c) (x + 10°) + (x + 20°) + x = 180°
3x + 30° = 180°
3x = 150°
x = 50°

Answer:
the thrid answer
Step-by-step explanation:
(6x^2+3x) + (x^2 - 4x -3)
plz help
Answer:
7x^2 - x -3
Step-by-step explanation:
(6x^2+3x) + (x^2 - 4x -3)
We have to use distributive property first to get rid of the parenthesis, so you simply have to multiply the positive (+) symbol with everything inside the second set of parenthesis.
+ * x^2 = x^2
+ * -4x = -4x
+ * -3 = -3
Now, we rewrite the equation which is
6x^2 + 3x + x^2 - 4x -3
Now you simply combine like terms.
6x^2 + x^2 = 7x^2
3x-4x = -x
The answer will be
7x^2 - x -3
Hope this helps!!

Answer:
7. 6
8. 6
9. 12
10. 6
11. 12
12. 24
Step-by-step explanation:
The length of each segment is AB = 6, BC = 6, AC = 12, CD = 6, CE = 12, AE = 24
What is the length?It is the measure of distance between the two points is called a length.
D is the mid-point of CE. Then
CD = DE = 6
B is the mid-point of AC. Then
AB = BC
C is the mid-point of AE. Then
AC = CE
AB + BC = CD + DE
AB + AB = CD + CD
2 AB = 2 CD
AB = CD
AB = 6
Then
AB = 6
BC = AB = 6
AC = AB + BC = 6 + 6 = 12
CD = DE = 6
CE = CD + DE = 6 + 6 = 12
AE = AB + BC + CD + DE = 6 + 6 + 6 + 6 = 24
