Answer:

166

Step-by-step explanation:

If the four lines are tangent to the circle, know that:

NA = KA

AD = LD

LC = MC

MB = NB

The question stated that:

NA = 18 --> KA is also 18

BN = 11 --> MB is also 11

AD = 34 --> LD is also 34

BC = 31 --> MC is 20 (Because BC is BM + MC and BM is 11)

We can just add these numbers.

(18+18) + (11 + 11) + (20+20) + (34+34)

= 36 + 22 + 40 + 68

= 76 + 90

= 166

The perimeter of ABCD is 166.

Answer:

130

Step-by-step explanation:

if 2 tangent segments are drawn to a circle from the same external point then they are congruent, then

AN = AK and KD = DL and  MC = LC

then AN = AK = 18 and

KD = AD - AK = 34 - 18 = 16 , so KD = DL = 16

now BM = BN = 11 , then

AB = AN + BN = 18 + 11 = 29

MC = BC - BM = 31 - 11 = 20 and LC = MC = 20 , so

CD = LC + LD = 20 + 16 = 36

-----------------------------------------

Perimeter = AB + BC + CD + AD

                 =  29 + 31 + 36 + 34

                 = 130

The length of the railing needed is 31.4 feet

From the question, we are to determine the length of railing needed

To determine the length of railing needed, we will determine the length of the arc formed by the balcony

Using the formula,

l = θ/360° × 2πr

Where l is the length of the arc

θ is the angle subtended by the arc

and r is the radius

From the given information,

θ = 45°

r = 40 feet

Putting the parameters into the equation, we get

l = 45°/360° × 2 × 3.14 × 40

l = 1/8 × 2 × 3.14 × 40

l = 2 × 3.14 × 5

l = 31.4 feet

Hence, the length of the railing needed is 31.4 feet

The volume of helium inside the balloon decreased at a rate of 0.1 cubic feet per minute. The linear equation that represents the given data is y = -0.1x + 6 and its slope m = -0.1.

The equation of the line passing through the points (x1, y1) and (x2, y2) is

(y - y1) = m(x - x1).

Where m is the slope of the line and is calculated by

m = (y2 - y1)/(x2 - x1)

The given data in the table represents the volume of helium (cu ft), inside a balloon relative to the elapsed time in minutes.

x: 5, 10, 15, 20, 25, 30, 35, 40

y: 5.5, 5, 4.5, 4, 3.5, 3, 2.5, 2

From this table, consider two points (5, 5.5) and (10, 5)

So, the equation of the line is

y- y1 = m(x - x1)

Where slope m = (y2 - y1)/(x2 - x1)

⇒ m = (5 - 5.5)/(10 - 5)

⇒ m = -0.5/5

∴ m = -0.1

Thus, the equation is

y - 5.5 = -0.1(x - 5)

⇒ y - 5.5 = -0.1x + 0.5

⇒ y = -0.1x + 0.5 + 5.5

⇒ y = -0.1x + 6.0

∴ y = -0.1x + 6

Since the slope of the line is negative, the volume of the helium inside the balloon decreased at a rate of 0.1 cubic ft per minute.

So, option 2 is correct.

Answer: Third Graph

Step-by-step explanation:

Given inequality

|x| + 1 > 2

Subtract 1 on both sides

|x| + 1 - 1 > 2 - 1

|x| > 1

Simplify the absolute value sign

x > 1 or x < -1

Apply the inequality to the graph

Since it is less than or greater than, the circle should be hollow

Since it is less than -1 or greater than 1, one line should point to the left and another should point to the right

Therefore, it should be the Third Graph

The relation that is a function is:

b. y = 2x² - 3x + 7

A relation is a function if each value of the input is mapped to only one value of the output.

Hence, when both x and y are squared, we have that [tex]x = \pm ay[/tex], hence it is not a function. This is the case for items a and c.

For item d, we have that the relation can be simplified as follows:

x = -y² + 3y

x = y(-y + 3)

The solution above, is associated to two values of y, hence it is also not a function. Then the function is given by:

b. y = 2x² - 3x + 7

In the solution, it can be seen that for each input x, only one value of y can be generated.

Answer:

-9

Step-by-step explanation:

To find the y intercept, substitute 0 in for x.

So, the equation looks like this:

[tex]y=6(0-\frac{1}{2} )(0+3)[/tex]

Now, just solve for y and you will get y = -9

The y-intercept of the graph of the equation is y = -9 which is the correct answer that would be an option (A).

The general equation of a line is y = mx + c

where m is the slope of the line and c is the intercept.

A linear equation is defined as an equation in which the highest power of the variable is always one.

Given equation as:

y = 6 (x - 1/2)(x+3)

To determine the y-intercept of the graph of the equation

Substitute the value x = 0 in the equation,

y = 6 (0 - 1/2)(0+3)

Apply the arithmetic operation and solve for y

y = -9

Hence, the y-intercept of the graph of the equation is y = -9.

Answer: 3

Step-by-step explanation:

The missing number in the simplified ratio ?/4 is 3.

Here, we have to find the missing number in the simplified ratio ?/4, we need to determine the ratio of girls to boys in Mr. Stevenson's class.

Given that there are 6 girls and 8 boys in the class, the ratio of girls to boys can be expressed as:

Number of girls : Number of boys = 6 : 8

To simplify the ratio, we can divide both the number of girls and the number of boys by their greatest common divisor (GCD).

In this case, the GCD of 6 and 8 is 2.

Dividing both 6 and 8 by 2, we get:

Number of girls : Number of boys = 6/2 : 8/2 = 3 : 4

So, the simplified ratio of girls to boys is 3/4.

Therefore, the missing number in the simplified ratio ?/4 is 3.

Answer:

  628.0 mm²

Step-by-step explanation:

The total surface area of the figure is the sum of the inside lateral area, the outside lateral area, and the area of the donut bases.

The lateral area of a cylinder is ...

  A = 2πrh

The total lateral area of the inside and outside cylinders is ...

  A = 2π(r1)h +2π(r2)h = 2π(r1 +r2)h

  A = 2(3.14)(3 mm +7 mm)(6 mm) = 376.8 mm²

The area of one donut base is the product of the centerline length and the width.

  A = πdw = (3.14)(7 mm +3 mm)(4 mm) = 125.6 mm²

The total surface area of the composite figure is the sum of its lateral area and the area of the two bases.

  surface area = 376.8 mm² +2×125.6 mm² = 628.0 mm²

__

Additional comment

The radius of the centerline of the base donut is the average of the inside and outside radii: half their sum. The diameter of the centerline circle is twice that average radius, so is equal to the sum of the inside and outside radii. This is the value we used above.

The width of the donut is the difference in the radii.

The product of the sum and difference is the same as the difference of the squares of the radii. That difference of squares would be what you have if you compute the overall area and subtract the inner area.

The value placed in the box that makes the system of equation with infinitely many solution is 12.

An infinite solution has both sides equal. For example, 6x + 2y - 8 = 12x +4y - 16.  If we simplify the equation we will notice both sides are equal. This means the equation has an infinitely many solution.

Hence,

y = -2x + 4

Therefore,

6x + 3y = 12

divide the equation(ii) by 3

2x + y = 4

y = -2x + 4

Therefore, both equation are equal if the the box is filled with 12. This means for the value placed in the box that makes the system of equation with infinitely many solution is 12.

Answer:

Step-by-step explanation:

Simply start by listing out the numbers from smallest to largest.

We start out with the smallest number following this information being the number 10. The next are 21 and 20. The next are 32, 31, and 30. We can start to see a pattern. If the ten's digit is n, then there are n numbers within that ten-group that have a greater 10's digit than unit's digit. The largest ten-group (90 to 98) has 9 integers following the rules established. Thus, the number of 2-digit integers that have ten's digits greater than units digit is 1+2+3+...+9=45

When searching for the value 10 in the array [2, 3, 5, 6, 9, 13, 16, 19], a recursive binary search algorithm will return false since the element is not found in the array.

About Binary Search Algorithm

The binary search algorithm, applied on arrays are of recursive type. The broad strategy is to look at the middle item on the list. The procedure of the binary search algorithm is either terminated (key found), the left half of the list is searched recursively, or the right half of the list is searched recursively, depending on the value of the middle element.

The function carrying out the binary search algorithm in a code returns true if the desired element is found in the array, else returns false. Since the element 10 is not present in the given array: [2, 3, 5, 6, 9, 13, 16, 19], the binary search algorithm will return false.

The transformation of f(x) to g(x) would be 6 units upwards

To transform f(x) to g(x), the equation is; g(x) = f(x) + 6

We are told that f of x passes through 1, 3 and 3, 13, and g of x passes through negative 1, 3 and 1, 13.

f(x) passes through (1,3) and (3, 13).

Thus;

slope is; m =  (13 - 3) / (3 - 1) = 10/2 = 5

y-intercept is; b = y - mx

Thus;

b = 3 - 5*1 = -2

Equation of the line is;
