How do I solve this arithmetic sequence and find the next four terms?

8 square feet = 2 hours

°divide 2hrs to 8 square feet

1hr = ?

2÷8 =4

so,

1hr = 4 square feet

•4 square feet can be painted in 1 hour.

*now to find how many square can be painted in 7 hrs.

°multiply no. of hours to hd no. of square feet per hour.

7hrs = ?

7×4 =28

So,

may this helps you

bye

Step-by-step explanation:

Answer:

B

Step-by-step explanation

f(x)=x2-4x-5

Becomes

f(x)=x2-5x+x-5

Take out the common factor

f(x)=(x-5)(x+1)

Equate the given function equal to 0

0=(x-5)(x+1)

And then

x-5=0 -- x=5

x+1 = 0 == x=-1

Answer:

B

Step-by-step explanation:

we are given a quadratic function

we want to figure out the form which we don't need change

so according to the question

[tex] \displaystyle{x}^{2} - 4x - 5 = 0[/tex]

rewrite -4x as x-5x:

[tex] \displaystyle{x}^{2} + x - 5x- 5 = 0[/tex]

factor out x:

[tex] \displaystyle \: x({x}^{} + 1)- 5x- 5 = 0[/tex]

factor out -5:

[tex] \displaystyle \: x({x}^{} + 1)- 5(x + 1 )= 0[/tex]

group:

[tex] \displaystyle \: (x + 1 )(x - 5)= 0[/tex]

hence our answer is B

Answer:

A parabola opens downward with vertex at (1,20)  

The function that models the height of bag of candies is

The graph of this function is a parabola that opens downward.

To find the maximum height of the candy bag, we complete the squares to obtain the vertex form of the function.

Factor -16 to get;

Add and subtract the square of half the coefficient of t.

Factor the perfect square trinomial:

The vertex is (1,20)

This means the maximum height after 1 second is 20 feet.

Answer:

x<=4, put the closed circle on "4" with the arrow going all the way left

Answer:

top box: ray

bottom box: endpoint

Step-by-step explanation:

top box: a ray is a line that doesn't stop and that is represented by a arrow on the end of it

bottom box: an end point is where a ray, or line segment stop and since i see two rays that stop there it is an endpoint

Answer:

I think x=0, and y=4

Step-by-step explanation:

P.S. I'm sorry if I'm wrong!

Answer:

The constant of proportionality is the ratio between two directly proportional quantities. Two quantities are directly proportional when they increase and decrease at the same rate.

The constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other. Once you know the constant of proportionality you can find an equation representing the directly proportional relationship between x and y, namely y=kx, with your specific k.

Hope this helps!

Answer:

The answer is B. 283.8 miles.[tex]\sqrt{b^2[/tex]

Step-by-step explanation:

Using the cosine rule:

b^2 = a^2 + p^2 - 2ap(cosB)

b^2 = 172.20^2 + 111.64^2 - 2 x 172.20 x 111.64(cos177.29)

b^2 = 42,116.33 - 38,448.82(cos177.29)

b^2 = 42,116.33 - (-38,405.82)

b^2 = 42,116.33 +38,405.82

b^2 = 80,522.15

[tex]\sqrt{b^2[/tex] = [tex]\sqrt{80,522.15}[/tex]

b = 283.76 miles = 283.8 miles

Answer:

500m

Step-by-step explanation:

a rectangle has 4 sides, so 30=60 and 20=40

60x5=300

40x5=200

300+200=500

500m

reason of 500

The main reason for this is he ran AROUND the rectangle and did it 5 TIMES, doing it once would be 100m.

Answer:

200π cm^2

Step-by-step explanation:

Sb = 8^2 π = 64π cm^2

a = sqrt2 [8^2 + 15^2] = sqrt2 [64 + 225] = sqrt (289) = 17 cm

Sl = 8x17xπ = 136 π cm^2

SA = 136π + 64π =200π cm^2

Answer:

Liz is correct

Step-by-step explanation:

Given

See attachment for complete question

Required

Who is correct? Daniel or Liz

From the attached data, we have:

[tex]Time: 1\frac{3}{4},\ 2\frac{1}{2},\ 2,\ 2\frac{3}{4},\ 1,\ 1\frac{3}{4},\ 1\frac{1}{4},\ 3,3\frac{1}{4},\ 3\frac{3}{4},\ 2,\ 2[/tex]

The total number of students is:

[tex]n = 12[/tex]

The data that represents  [tex]2\frac{1}{2}[/tex] or more is:

[tex]Time: 2\frac{1}{2},\ 2\frac{3}{4},\ 3,3\frac{1}{4},\ 3\frac{3}{4}[/tex]

The frequency of this is 5

The frequency that represents [tex]2\frac{1}{2}[/tex] or less will be 7

This means that less than half spend [tex]2\frac{1}{2}[/tex] or more

and more than half spend [tex]2\frac{1}{2}[/tex] or more

Hence, Daniel is incorrect. Liz is correct
