The polynomial that represents the length is:

h(x) = 11x + 1.

We know that the area of the top surface is given by:

f(x) = 66x^2 + 17x + 1

And the width of the top surface is:

g(x) = 6x + 1.

We can assume that the length, h(x), is another polynomial of degree 1, so we can write:

h(x) = a*x + b

Now, the area is the product of the width and the length, so we have:

f(x) = g(x)*h(x)

f(x) = (6x + 1)*(ax + b)

     =   6ax^2 + (6b)x + (a)x + b

     =   (6a)x^2 + (6b + a)x + b

Now let's compare this with f(x), correspondent coefficients must have the same value.

66x^2 + 17x + 1 = (6a)x^2 + (6b + a)x + b

Then we have:

66 = 6a

17 = 6b + a

1 = b

From the first equation we have:

66/6 = a = 11

And from the third:

b = 1

Then the length is:

h(x) = 11x + 1.

Answer:

3/5

Step-by-step explanation:

I did this on the test and I got this specific answer correct :)

The required mean of the data set is 3/5, or approximately 0.6 inches.

The mean of the values is the ratio of the total sum of values to the number of values.

Here,
To find the mean of the data set, we need to add up all the values and divide by the total number of values.

1/4 + 1 1/3 + 2/3 + 1/4 + 1/2 = 1/4 + 4/3 + 2/3 + 1/4 + 1/2 (we convert all fractions to have a common denominator)

= 2/3 + 4/3 + 1

We need to convert these mixed numbers to improper fractions:

= 3

Now we divide by the total number of values:

= 3 ÷ 5

= 3/5

Therefore, the mean of the data set is 3/5, or approximately 0.6 inches.

Answer:

0, 3, -6, 7

Step-by-step explanation:

x(x − 3)(x + 6) (x – 7) = 0

so x = 0

or x - 3 = 0, x = 3

or x + 6 = 0, x = -6

or x - 7 = 0, x = 7

Answer: 0, 3, -6, 7

Answer:

It is, in fact, a rational number.

Answer:

80

Step-by-step explanation:

The rule for triangles is that their angles must add up to 180. 30+50=80 and 180-80=100 so the angle next to 4 is 100. Since they are on a straight line the angle is 180 and 180-100 is 80

Answer:

x = 15/8

Step-by-step explanation:

Let x = unknown number

Given:

some number minus -15 is equal to the product of the number and 9

⇒ x - -15 = x · 9

⇒ x + 15 = 9x

⇒ 15 = 9x - x

⇒ 15 = 8x

⇒ x = 15/8

Answer:

15/8

Step-by-step explanation:

Let's assume that the number is 'n'. Provided that number 'n' minus -15 is equal to the product of the number 'n' and 9. Simply jot down the above statement in mathematical form:

[tex] \implies\:\sf{\red{n \: - \: ( - 15) \: = \: n \: \times \: 9}}[/tex]

Now, simply solve the above equation.

[tex]\implies\:\sf{n \: + \: 15 \: = \: 9n}[/tex]

Take the like terms on one sides.

[tex]\implies\:\sf{9n \: - \: n \: = \: 15}[/tex]

Do the rest calculations.

[tex]\implies\:\sf{8n \: = \: 15}[/tex]

[tex]\implies\:\sf{\red{n \: = \: \dfrac{15}{8}}}[/tex]

Hence, the required value of n is 15/8.

A confidence interval is simply the range of estimates for an unknown parameter, which is defined as an interval with a lower bound and an upper bound.

Your information is incomplete as the data is not given. Therefore, an overview of the confidence interval will be given.

A 90% confidence interval means that the researcher is 90% confident that the values of the results will simply fall between the upper and lower limits if the procedure is repeated again.

You can find a confidence level for data by simply taking half of the size of the confidence interval, then multiplying it by the square root of the sample size, and then dividing by the sample standard deviation.

Finally, look up the resulting ​Z​ or ​t​ score in a table in order to find the level.

C. 240 in^2

Step-by-step explanation:

is it stated that two triangles are similar.

If they are similar then their area must be proportional too.

The side lengths' proportion is :

12/60 = 1/5 this can be used to find the area of the smaller triangle, ABC
Let x represent the are of triangle ABC

1/5 = x/1200 cross multiply both sides

5x = 1200 divide both sides by 5

x = 240 since the area is indicated with square value so the answer is

Answer:

The shorter piece is 28 inches

The long piece is 56 inches

Step-by-step explanation:

    First, we need to write an equation:

-> Let x be the shorter piece after they are cut.

84 inches = x + 2x

84 inches = 3x

28 inches = x

x = 28 inches

    Now we will find the length of each piece,

-> The shorter piece is 28 inches

         [] x = 28 inches

-> The long piece is 56 inches

         [] 2x = 2(28) = 56 inches

Checking work:

56 + 28 = 84

-> This solution should work
