The exterior angle at K in triangle HJK is 139°, whereas the exterior angle at J is 53°. Shortest side is JK.

We know that the sum of exterior angles of a triangle is 360°. So,

Exterior angle at K + exterior angle at J + exterior angle at H = 360°

139 + 53 + exterior angle at H = 360

exterior angle at H + 192 = 360

exterior angle at H = 360 - 192

exterior angle at H = 168°

Now, we will calculate the interior angles of triangle HJK. We know that exterior and interior angles are supplementary and makes a sum of 180 degree.

Interior angle K + exterior angle K = 180

Interior angle K + 139 = 180

Interior angle K = 180 - 139 = 41°

Interior angle H + exterior angle H = 180

Interior angle H + 168 = 180

Interior angle H = 180 - 168 = 12°

Interior angle J + exterior angle J = 180

Interior angle J + 53 = 180

Interior angle J = 180 - 53 = 127°

A triangle's shortest side is always opposite the smallest angle. So, in this question the smallest angle is ∠H and the side opposite to it is KJ, hence KJ is the shortest side.

The values of lengths are:  AE = 30, GF = 10, GD = 5 for the given ΔABC.

Point at which all three medians of a particular triangle meet is called as a centroid. Median also called as a line segment which connects the vertex of a triangle to the midpoint.

Since G is the centroid of ΔABC, it divides each median in the ratio  of 2:1. That is,

AG:GE = 2:1,     BG:GF = 2:1,     CG:GD = 2:1

First, we know, AG/GE = 2/1         (given, AG = 20)

20 / GE = 2/1

GE = 10

So, given in the median of ΔABC is,

AE = AG + GE      (put the values)

AE = 20 + 10

AE = 30

Now, we can use the fact that BG:GF = 2:1 to find the length of GF:

we know, BG/GF = 2/1         (given, BF = 30 = BG + GF)

BG = 2GF

(BF - GF) = 2GF                     (here, BG = BF - GF)

30 - GF = 2GF

GF = 10

Now, we can use the fact that CG:GD = 2:1 to find the length of GD:

we know, CG/GD = 2/1         (given, CG = 10)

10 / GD = 2/1

GD = 5

Therefore, we get the values are:  AE = 30, GF = 10, GD = 5

If for an arithmetic-sequence, the terms are t₅ = -154 and t₉ = -274, then the first-three terms are t₁ = -274, t₂ = -244 and t₃ = -214.

An "Arithmetic-Sequence" is defined as a sequence of numbers in which the difference between any two consecutive terms is always the same, which is called the "common-difference".

To find first 3 terms of an "arithmetic-sequence" given the values of t₅ and t₉, we use formulas for "nth-term" of an arithmetic sequence, which is

⇒ tₙ = t₁ + (n - 1)d,

where tₙ = nth term, t₁ = first term, n = position of term in sequence, and d = common-difference,

Given that t₅ = -154 and t₉ = -274,

So,

⇒ t₅ = t₁ + (5 - 1)d = -154,

⇒ t₉ = t₁ + (9 - 1)d = -274,

We first find the "common-difference" by subtracting "t₁" from both sides of first equation and "t₉" from both sides of second-equation,

We get,

⇒ 4d = -154 - t₁,

⇒ 8d = -274 - t₁,

Simplifying further,

We get,

⇒ 4d = 120,

⇒ d = 30,

Now, we substitute it in "4d = -154 - t₁",

We get,

⇒ 4(30) = -154 - t₁,

⇒ 120 = -154 - t₁,

⇒ t₁ = -154 - 120,

⇒ t₁ = -274

So, the first term is = -274;

Now we use "d = 30" to find second and third terms of sequence,

We get,

⇒ t₂ = t₁ + (2 - 1)d = -274 + 30 = -244,

⇒ t₃ = t₁ + (3 - 1)d = -274 + 60 = -214,

Therefore, first three-terms of arithmetic sequence are -274, -244, and -214.

The length of curve DE, which is 5% longer than line segment AB, is 10.5 units.

To calculate the length of curve DE, we first need to determine the length of line segment AB. Let's say, for example, that line segment AB has a length of 10 units. To find the length of curve DE, we need to add 5% of line segment AB's length to line segment AB.

To calculate 5% of line segment AB's length, we can multiply the length of line segment AB by 0.05. This gives us:

5% of 10 = 0.05 x 10 = 0.5

So, 5% of line segment AB's length is 0.5 units. To find the length of curve DE, we need to add 0.5 units to the length of line segment AB. This gives us:

Length of curve DE = Length of line segment AB + 5% of Length of line segment AB

Answer: $34,828.59

Step-by-step explanation:

We can use the formula for compound interest to solve this problem:

A = P(1 + r)^t

where:

P = the principal (in this case, $14,275)

r = the annual interest rate (6%, or 0.06 as a decimal)

t = the number of years (18)

Plugging in the values we know, we get:

A = $14,275(1 + 0.06)^18

A = $14,275(1.06)^18

A = $34,828.59 (rounded to the nearest penny)

Therefore, the value of the investment after 18 years, rounded to the nearest penny, is $34,828.59

Answer:

y=-0.5x+3

Step-by-step explanation:

The equation of a line is

y=mx+b, with m being the slope, and b being the y-intercept

The slope is -0.5, and the y intercept is 3

so:

y=-0.5x+3

Answer:

y= -1/2x+3

Expiation:

you can find the equation between two points by using the slope formula and the slope intercept form which is y=mx+b.

An equation of the line that passes through the point (6,2) and has a slope of -1/2 is y = -1/2(x) + 5.

In Mathematics and Geometry, the point-slope form of a straight line can be calculated by using the following mathematical expression:

y - y₁ = m(x - x₁)

Where:

At data point (6, 2) and a slope of -1/2, a linear equation for this line can be calculated by using the point-slope form as follows:

y - y₁ = m(x - x₁)

y - 2 = -1/2(x - 6)  

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

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

y = -1/2(x) + 5

Answer: $31,920.

Step-by-step explanation:

The banker's rule is a method used by lenders to determine the maximum amount of money that a borrower can afford to repay. According to this rule, the maximum amount of money that Lee can afford to borrow is determined by multiplying his annual income by a factor of 0.28.

Using this rule, the amount that Lee can afford to borrow can be calculated as:

Maximum affordable monthly payment = 0.28 x monthly income

Maximum affordable monthly payment = 0.28 x (24700/12)

Maximum affordable monthly payment = 0.28 x 2058.33

Maximum affordable monthly payment = 576.66

Therefore, Lee can afford to make monthly payments of up to $576.66. To calculate the total amount he can borrow, we need to determine the total cost of the loan, including principal and interest.

Assuming a 5-year loan with an interest rate of 4%, the total cost of the loan can be calculated using an online loan calculator or spreadsheet software.

Plugging in the numbers, the total amount that Lee can borrow is approximately $31,920.

It's important to note that this calculation is based on the banker's rule and assumes that Lee has no other debt obligations. Actual loan approval and loan amounts may vary depending on other factors such as credit score, debt-to-income ratio, and other lender-specific requirements.

Lateral surface area = 2H(L + W)

Total surface area = 2 LW + 2 WH + 2 HL

We need to know the prism's dimensions in order to determine its lateral and total surface area for a rectangular base prism. The rectangular prism's length, width, and height are assumed to be L, W, and H, respectively.

The sum of the areas of the rectangular prism's four lateral faces determines its lateral surface area. Since every sidelong face is a square shape with a level of H and a width of one or the other L or W, the parallel surface region is given by:

Lateral Surface Area = 2H(L + W)

The sum of the areas on each of the six faces creates the rectangular prism's total surface area. This incorporates the four sidelong faces, as well as the top and base faces, which are additionally square shapes with aspects L x W. Consequently, the all out surface region is given by:

Total Surface Area = 2(LW + LH + WH)

The diameter of the balloon is increasing at a rate of approximately 0.79 ft/min when the diameter is 1.5 feet.

We can use the formula for the volume of a sphere to relate the rate of change of volume with the rate of change of diameter

V = (4/3)πr^3 = (1/6)πd^3,

where V is the volume, r is the radius, and d is the diameter.

Taking the derivative with respect to time t, we get

dV/dt = (1/2)πd^2 (dd/dt),

where dd/dt is the rate of change of diameter.

We are given that dV/dt = 2.8 ft^3/min and d = 1.5 ft, so we can solve for dd/dt

dd/dt = (2dV/dt)/(πd^2) = (2(2.8))/(π(1.5)^2) ≈ 0.79 ft/min.

Step-by-step explanation:

If you think math is boring, think again. Here is a fun way to learn how to find the rational number that we need to divide -15/56 by to get -5/7. It's like a puzzle, but with fractions!

First, we need to make -15/56 look nicer. How do we do that? By dividing both the top and the bottom by -1. That's like flipping the sign. So we get 15/56. Much better!

Next, we need to find a mystery number that makes -5/7 and 15/56 equal when we multiply them. That's like finding a missing piece of a jigsaw puzzle. How do we do that? By cross-multiplying! That's when we multiply the top of one fraction by the bottom of the other and set them equal. So we get:

-5 times 56 equals 15 times mystery number

Now we just need to solve for the mystery number. How do we do that? By dividing both sides by 15. That's like cutting a cake into equal slices. So we get:

Mystery number equals (-5 times 56) divided by 15

Now we just need to simplify. How do we do that? By using a calculator or our brains. Either way, we get:

Mystery number equals -18.67

And that's it! We found the rational number that we need to divide -15/56 by to get -5/7. It's -18.67. Isn't math fun?
