radius is 7 centimeters. (Use it - 3.14)
[A] 43.96 cm [B] 0.897 cm
[C] 21.98 cm [D] 0.449 cm

Answer: 6 feet long

Step-by-step explanation:

1ft. = 12 in

62 inches = 5 feet and 2 inches

Break down 62 into 60 and 2

60 divided by 12 = 5 (12x5=60)

60in. = 5ft.

2in. = 2in.

5ft. and 2in.

10in.= 10in.

Add the inches

10in. + 2 in. = 12 in.

12in.= 1ft.

5ft. + 1ft. = 6ft.

\(\text{Solve for z:}\\\\-p(51+z)=dz+84\\\\\text{Use the distributive property}\\\\-51p-pz=dz+84\\\\\text{Add 51p to both sides}\\\\-pz=51p+dz+84\\\\\text{Subtract dz from both sides}\\\\-pz-dz=51p+84\\\\\text{Factor out z}\\\\z(-d-p)=51p+84\\\\\text{Divide both sides by (-d - p)}\\\\z=\frac{51p+84}{(-d-p)}\\\\\text{The denominator shouldn't be zero, so we have to make it positive}\\\\\boxed{z=\frac{-51p-84}{d+p}\,\,or\,\,z=-\frac{51p+84}{d+p}}\)

Answer:

\( \boxed{\sf z = \frac{ - 51p - 84}{ p + d} \ \ \ OR \ \ \ z = - \frac{51p + 84}{ p + d} } \)

Step-by-step explanation:

\( \sf solve \: for \: z : \\ \sf \implies −p(51+z)=dz+84 \\ \\ \sf Expand \: out \: terms \: of \: the \: left \: hand \: side: \\ \sf \implies - 51p - pz = dz + 84 \\ \\ \sf Subtract \: d z - 51 p \: from \: both \: sides: \\ \sf \implies - 51p - pz - (dz - 51p)= dz + 84 - (dz - 51p) \\ \\ \sf - (dz - 51p) = - dz + 51p : \\ \sf \implies - 51p - pz - dz + 51p= dz + 84 - dz + 51p \\ \\ \sf - 51p + 51p = 0 : \\ \sf \implies - pz - dz = dz + 84 - dz + 51p \\ \\ \sf dz - dz = 0 : \\ \sf \implies - pz - dz = 84 + 51p \\ \\ \sf \implies z( - p - d) = 84 + 51p \\ \\ \sf Divide \: both \: sides \: by \: - p - d: \\ \sf \implies z = \frac{51p + 84}{ - p - d} \\ \\ \sf \implies z = \frac{51p + 84}{ -( p + d)} \\ \\ \sf \implies z = \frac{ - (51p + 84)}{ p + d} \\ \\ \sf \implies z = \frac{ - 51p - 84}{ p + d} \)

When plate is rotated 720° about the origin in the counterclockwise direction they form parallel segments.

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

The coordinates of the figure EFGH are given as:

E = (-4,8)

F = (-7,5)

G = (-4,3)

H = (-2,5)

The rule of rotation 720 degrees counterclockwise about the origin in the

(x,y) -> (-y,x)

So, we have:

E' = (-8, -4)

F' = (-5, -7)

G'= (-3, -4)

H' = (-5, -2)

when plate is rotated 720° about the origin in the counterclockwise direction they form parallel segments.

Hence when plate is rotated 720° about the origin in the counterclockwise direction they form parallel segments.

We can reject the null hypothesis and conclude that there is evidence to support the alternative hypothesis that the left foot is longer than the right foot.

A statistical test is required to determine whether the length of the left foot is greater than the length of the right foot. The null hypothesis states that there is no difference in average length between the left and right feet. The alternative hypothesis is that the left foot's average length is greater than the right foot's average length.

This hypothesis is one-tailed, as we are only interested in whether the left foot is longer than the right foot. We are not considering the possibility that the right foot could be longer than the left foot.

A t-test can be used to determine whether the difference in average length between the left and right feet is statistically significant. We can reject the null hypothesis and conclude that there is evidence to support the alternative hypothesis that the left foot is longer than the right foot if the p-value of the t-test is less than the chosen significance level (e.g., 0.05).

The property you are referring to is called the associative property of multiplication. According to this property, when multiplying three numbers, the grouping of the numbers does not affect the result. In other words, you can change the grouping of the factors without changing the product.

In the equation you provided: 3x(5x7) = (3x5)7

The associative property allows us to group the factors in different ways without changing the result. So, whether we multiply 5 and 7 first, or multiply 3 and 5 first, the final product will be the same.

The length of the line segment MN is given as follows:

5.83 units.

Suppose that we have two points with coordinates \((x_1,y_1)\) and \((x_2,y_2)\).

The shortest distance between them is given by the equation presented as follows:

\(D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\)

The endpoints of the line segment MN is given are given as follows:

M(5,6) and N(2,1).

Hence the length of the segment is given by the distance of these two points:

L = sqrt((5-2)² + (6-1)²)

L = sqrt(34)

L = 5.83 units.

The average rate of change in the number of Americans over the age of 65 from 2000 to 2015 is approximately -2.09 million people per year.

To find the average rate of change in the number of Americans over the age of 65 from 2000 to 2015, we need to calculate the change in the number of people over 65 during that time period and divide it by the number of years:

Number of people over 65 in 2015:

n(15) = 0.00246(15)^2 + 0.118(15) + 0.183

n(15) = 2.781 million people

Change in the number of people over 65 from 2000 to 2015:

2.781 million - 34.42 million = -31.639 million people

Average rate of change:

-31.639 million / 15 years = -2.09 million people per year

Answer: 4000

Step-by-step explanation:

The required quadratic polynomial is  \(x^{2} - 8x + 12 =0\) and roots of this quadratic polynomial are 2 and 6.

Let the roots of the quadratic equation be  \(\alpha\) and \(\beta\) .

Given,  

          Sum of zeroes,  \(\alpha +\beta = 8\)

           Product of Zeroes, \(\alpha *\beta = 12\)

we know that,

      Quadratic Equation can be written as :

                     \(x^{2} - (\alpha + \beta )x + \alpha \beta =0\)

     Substituting the values in the above Equation,

                    \(x^{2} - (8)x + (12) =0\)

                    \(x^{2} - 8x + 12 =0\)

Hence, The required quadratic equation is \(x^{2} - 8x + 12 =0\) .

Now, let's factorize the equation to find its root:

                    \(x^{2} - 8x + 12 =0\)

                    \(x^{2} - 6x -2x+ 12 =0\)

                    \(x(x-6) -2(x-6)=0\)

                     \((x-6)(x-2)=0\)

                    ⇒ \(x= 2,6\)

Therefore roots of the quadratic equation \(\alpha ,\beta\) are \(2,6\) .

We know the the total of angles for a triangle is 180 degrees.

So in this case we'd want to set up adding all of our angles and setting them equal to 180

17 + 126 + b = 180

then solve for b

143 + b = 180

b = 37 degrees
