which function is graphed?

Answer:

We have to use the summation in this case.

Step-by-step explanation:

total/frequency=mean

frequency= 2 + 8 + 4 + 10 + 6=30

0*2=0

1*8=8

2*4=8

3*10=30

4*6=24

total= 70

70/30= 7/3= 2.33333... ≈ 2 (goals cannot be in decimals!)

This should be the answer, I hope.

Answer:

x^4 +y+1

Step-by-step explanation:

The quadratic function in vertex form whose graph has the vertex (1, 0) and passes through the point (2, -17) is [tex]-17(x-1)^{2}[/tex].

The vertex form of a quadratic function is [tex]f(x) = a(x-h)^{2} + k[/tex] where a, h, and k are constants and (h, k ) is the vertex of the graph of the function.

According to the given question we have

The graph has the vertex is (1, 0) and passes through (2, -17)

Since, the general form of a quadratic function in a vertex form  is

[tex]y = a(x-h)^{2}+ k[/tex]

substitute, h = 1 and k = 0 in the above equation

⇒ [tex]y = a(x-1)^{2} +(0)^{2}...(i)[/tex]

Also, the graph passes through the point (2, -17)

⇒ [tex]-17 = a(2-1)^{2}[/tex]

⇒ -17 = a or a = -17

Substitute the value of a in equation (i).

⇒[tex]y = -17(x-1)^{2}[/tex]

Therefore, the quadratic function in vertex form whose graph has the vertex (1, 0) and passes through the point (2, -17) is [tex]-17(x-1)^{2}[/tex].

#SPJ2

Answer:

33 years, 7 months

Step-by-step explanation:

Using the compound interest formula Accrued Amount = P (1 + r/n)^(nt)

where Accrued amount (A) is the expected future balance

A = $8000

P = principal; $5000

r = 1.4% = 0.014

t = number of years

n = number of times interest is compounded = 12 for monthly

Therefore

8000 = 5000 (1 + 0.014/12)^(12t)

Therefore

(1.001167)^12t = 8000/5000

(1.001167)^12t = 1.6

finding the log of both sides

12t x log 1.001167 = log 1.6

12t = log 1.6 / log 1.001167

12t = 402.98

t = 402.98/12

t = 33.58

hence time to increase the balance is 33 years, 7 months

Answer:

The aquarium​ hold 60000 ml and in liters is 60 liters

Step-by-step explanation:

Length of aquarium = 40 cm

Breadth of aquarium = 30 cm

Height of aquarium = 50 cm

Volume of tank =[tex]Length \times Breadth \times Height[/tex]

Volume of tank = [tex]40 \times 30 \times 50[/tex]

Volume of tank =[tex]60000 cm^3[/tex]

Now , 1 cubic cm = 1 ml

60000 cubic cm = 60000 ml

Now 1000 ml = 1 l

60000 ml = [tex]\frac{60000}{1000}=60 liters[/tex]

So,  the aquarium​ hold 60000 ml and in liters is 60 liters

For a line with a positive slope that passes through (0, 1), the points that can't be on the line are:

(-3, 1) and (5, -2)

We know that the line passes through the point (0, 1) and has a positive slope. This means that for values of x larger than x = 0, the values of y in the line will be larger than 1.

Then if we find a point with:

x > 0

y ≤ 1

That point clearly can't belong to our line.

And points with:

x < 0

y ≥ 1

Also can't belong to the line.

Then the correct options are: (-3, 1) and (5, -2)

Answer: 153.86 cm²

Step-by-step explanation: To find the area of the circle shown here, start with the formula for the area of a circle which is A = πr².

Notice that here, we're given the diameter instead of the radius.

Remember that the radius is equal to half of the diameter.

So the radius of this circle will be equal to half of 14 cm or 7 cm.

So plugging into the formula, we have (π)(7 cm)².

A common mistake is to plug 14 cm into the formula but remember

that we must plug in the radius and not the diameter.

Multiplying, (7 cm)² is equal to (7 cm)(7 cm) or 49 cm².

So we have 49π cm².

So the area of the circle shown here is 49π cm².

Now, remember that π is approximately equal to 22/7 or 3.14 so we

can estimate the area of the circle by plugging in 3.14 for π.

So we have (49)(3.14) which is equal to 153.86 cm².

So the area of the circle is approximately equal to 153.86 cm².

Answer: 55 miles per hour

Step-by-step explanation:

Here is the complete question:

Seth's family plans to drive 220 miles to their vacation spot. They would like to complete the drive in 4 hours.

Find the average speed in miles per hour needed to make the trip in the desired.

From the question, Seth's family plans to drive 220 miles to their vacation spot and they would like to complete the drive in 4 hours.

Average speed is calculated as distance travelled divided by the time taken. This will be:

Speed = Distance/Time

Average speed = 220/4

Average speed = 55 miles per hour

Answer:

55%

Step-by-step explanation:

We need to first find the total length of the side.

let remaining length be x

perimeter= 40cm

4 (s)=perimeter

4(7+x)=40

28+4x=40

4x=40-28=12

4x=12

x=12/4=3

total length= 7+3= 10cm

4+y= 10=

y=6

therefore, area of square= s*s= 10*10=100cm²

find areas of the two triangles (unshaded).

1/2*3*10= 15cm²

1/2*6*10= 30 cm²

15/100*100= 15%

30/100*100= 30%

shaded percentage= 100-(15+30)

= 100-45

= 55%

Answer:

0.565 m^3 to the nearest thousandth.

Step-by-step explanation:

The volume of the cylinder = π r^2 h

Here the radius r = 1/2 diameter

= 1/2 * 3 = 1.5 m

8 cm = 0.08 m.

So the volume = π (1.5)^2 * 0.08

= 0.565 m^3 to the nearest thousandth.
