Answer:

Step-by-step explanation:

The measure of x, AB, BC, and AC are 8, 69, 69 and 138 respectively

The point where two lines meet is known as an angle:

Given the following expressions

AB = 3(3x -1)

AC = 5(2x+2)

If B lies in the middle of AC then;

Hence;

AB + AB = AC

2AB = AC

2(9x-3) = 5(2x+2)

18x - 6 = 10x + 10

18x - 10x = 10 + 6

2x = 16

x = 16/2

x = 8

Get AB

AB = 9x - 3

AB = 9(8) - 3

AB = 72 - 3

AB = 69

Since AB = BC, hence the measure of BC os 69

Get the measure of AC:

AC = AB + BC

AC = 69 + 69

AC = 138

hence the measure of x, AB, BC, and AC are 8, 69, 69 and 138 respectively

The area of the concave hexagon AOBCPD is 36 square units.

The concave hexagon AOBCPD is formed by two externally tangent circles with centers O and P and radii 2 and 4, respectively. Points A and B are on the circle with center O, and points C and D are on the circle with center P. Lines AD and BC are common external tangents to the circles.

To find the area of the hexagon, we can divide it into two trapezoids: AOCP and BOCD. In each trapezoid, the shorter base is a radius of the smaller circle (2 units) and the longer base is a radius of the larger circle (4 units). Since AD and BC are tangent to the circles, they are perpendicular to the radii at the points of tangency, forming right angles. This means the height of each trapezoid is the same, and it is the distance between the centers O and P (6 units).

Let's use the formula for the area of a trapezoid: (1/2)(sum of parallel sides)(height). For trapezoid AOCP: (1/2)(2+4)(6) = 18 square units. For trapezoid BOCD: (1/2)(2+4)(6) = 18 square units. The total area of hexagon AOBCPD is the sum of the areas of the two trapezoids: 18 + 18 = 36 square units. Therefore, the area of the concave hexagon AOBCPD is 36 square units.

An equation of the tangent line to the curve y=√x at at the given point. y = x and (9, 3) is \(y - 3 = (1/6)(x - 9)\).

The equation of the tangent line to the curve y = √x at the point (9, 3), we first need to find the slope of the tangent line. We can do this by finding the derivative of the function y = √x, which is:

= \(y' = 1/(2√x)\);

Substituting x = 9 into this formula gives us:

= \(y' = 1/(2√9) = 1/6\).

So the slope of the tangent line at the point (9, 3) is 1/6.

Next, we use the point-slope form of the equation of a line to write the equation of the tangent line. The point-slope form is: \(y - y1 = m(x - x1)\); where m is the slope of the line and (x1, y1) is a point on the line. We can use (9, 3) as the point on the line, and the slope we just found as m, so we get:

\(y - 3 = (1/6)(x - 9)\).

So, \(y - 3 = (1/6)(x - 9)\) is the equation of the tangent line to the curve y = √x at the point (9, 3).

Answer:

2/5

Step-by-step explanation:

The slope of the line

y=2/5x-4

is 2/5 since it is in the form y = mx+b where m is the slope

Parallel lines have the same slope so a line that is parallel to  y=2/5x-4 has a slope of 2/5

The value of  variable x in the equation is 16.

The equation represented as follows:

x + 14 + x³ = 78

The value x is the variable.

A variable is number represented with a letter in an equation.

Therefore,

x + 14 + 3x = 78

subtract 14 from both sides of the equation

x + 3x + 14 - 14 = 78 - 14

x + 3x = 64

Therefore,

4x = 64

divide both sides by 4

The rock is falling with a velocity of approximately 31.36 m/s downward.

To determine the speed of the rock falling after 3.2 seconds, we need to know the acceleration due to gravity (g) and assume no air resistance.

The acceleration due to gravity is approximately 9.8 m/s² (on Earth near the surface). Assuming the rock falls vertically downward, its velocity (v) can be calculated using the equation:

v = gt,

where

v is the velocity,

g is the acceleration due to gravity, and

t is the time.

Substituting the given values, we have:

v = (9.8 m/s²)(3.2 s)

= 31.36 m/s.

Therefore, after 3.2 seconds, the rock is falling with a velocity of approximately 31.36 m/s downward.

Jamie should accept the second option to buy a new refrigerator for his apartment.

What is the Annual Interest?

The annual interest rate on an amount borrowed or a loan is the increment added to the loan at a particular rate over the desired period of time.

The objective of this question is to weigh the two options and determine the best means by which Jamie could get a new refrigerator for his apartment.

Option 1:

The annual interest rate for the first card = $1300 x 16.5%

The annual interest rate = $214.5

The monthly finance charge on a credit card can be estimated by finding the average daily balance using the Annual interest rate and the days of the billing cycle.

The monthly finance charge

= 1300 x 0.165/12

The monthly finance charge = $17.88

Now, The minimum monthly payment is 100 + 17.88

The minimum monthly payment for the first month = $117.88

In 12 months, Jamie would have paid off the loan with an additional interest of $214.5

Total amount paid = (117.88 x 12) + 247.5

= $1629.06

Option 2.

The appliance store offers an installment loan;

Using;

S.I. = PRT / 100

Since the loan must be paid in 12 equal payments; we can say the loan is paid monthly which is equivalent to 1 year.

i.e., Time(T) = 1 year

S.I. = 1300 x 12.5 x 1 / 100

The down payment = $300

In the total amount of $1300, Jamie has an outstanding amount of $1000 to pay.

Thus, In 12 equal payment times,

Jamie gets to pay = $1000/12

Jamie gets to pay = $ 83.33 each time .

Total amount paid = $162.5 + 1300

Total amount paid = $1462.5

Therefore, we can conclude that Jamie should accept the second option

to buy a new refrigerator for his apartment since the total amount paid in option 2 is lesser than that of option 1.

b) The probability that the sum of the numbers drawn is 4 is 2/9.

c) The probability that the sum of the numbers is at least 4 is 2/3.

a) The probability of an event is measured between 0 and 1, and the probability space is a collection of all probable results, hence the probability space is:

P= (1, 1), (1, 2), (1, 3), (2, 1), (2, 2), (2, 3), (3, 1), (3, 2), (3, 3)

Hence, the probability space can be written as a set, S = {1,2,3}.

b) If 2 balls are drawn and sum of the numbers is 4, then there could be only one probable way of drawing the balls, which is ball 1 and 3, so probability that the sum of the numbers is 4 is:

P = 2/9

c) If 2 balls are drawn and sum of the numbers is at least 4, then probable ways of drawing the balls are:

(1,3), (2,2), (2,3), (3, 1), (3, 2), and (3, 3)

Hence, the probability that the sum of the numbers is at least 4 = 6/9 = 2/3

The answer to number 1 is geometric sequence of A>

Step-by-step explanation:

The function grows without bound or approaches negative infinity as x becomes very large or very small, then the equation for the horizontal asymptote is either y = infinity or y = negative infinity, respectively.

Without knowing the specific function and transformation, it is difficult to provide a specific equation for the transformed function and horizontal asymptote. However, in general, the equation for a transformed function can be written as:

y = a*f(b(x - h)) + k

Where a, b, h, and k are constants that represent the amplitude, period, horizontal shift, and vertical shift of the function, respectively. f(x) is the original function, and the transformation involves scaling, shifting, or reflecting the function. Depending on the transformation, one or more of the constants a, b, h, and k may change.

The equation for the horizontal asymptote depends on the behavior of the function as x approaches positive or negative infinity. If the function approaches a constant value as x becomes very large or very small, then the equation for the horizontal asymptote is simply that constant value. If the function grows without bound or approaches negative infinity as x becomes very large or very small, then the equation for the horizontal asymptote is either y = infinity or y = negative infinity, respectively.

The measure of Angle A in Quips is 4 Quips. The measure of Angle B in Quips is 25 Quips.

Since, Angle A has a measure of 8 Gips and a full rotation measures 15 Gips, the arc subtended by Angle A's rays is 8/15 (or 4/7) of the circumference of any circle centered at Angle A's vertex.

Similarly, since a full rotation measures 6 Quips, the measure of Angle A in Quips is (8/15) * 6 = 3.2 Quips. Rounding to the nearest Quip, the measure of Angle A in Quips is 3 Quips.

To find the measure of Angle B in Quips, we use the fact that the measure of Angle B in Gips is 12.5 Gips. Since a full rotation measures 15 Gips, the measure of Angle B in Quips is (12.5/15) * 6 = 5 Quips.

Therefore, the measure of Angle B in Quips is 5 Quips.
