Given g(x)=4x-2/5 find the inverse

Answer:

Harper is 17 and Cadence is 44.

Step-by-step explanation:

First, we can set up an equation to displays the sum of both ages.

Let x = Harper's age and y = Cadence's age

x+y=61

8 years ago, this means the sum will decrease by a total of 16 as we have to subtract 8 from both variables

The equation to represent 8 years ago is: x+y=45

Now we can write another equation to represent Cadence being 4 times older than Harper (8 years ago)

y=4x

We can substitute this back into the equation we had for the ages 8 years ago.

x+(4x) = 45

5x=45

x=9

Now, Harper's age 8 years ago is 9 years old. We add 8 to this number to determine that Harper is currently 17 years old.

We can insert this into the original equation to determine Cadence's age.

17+y=61

y=44

Thus, Cadence is currently 44 years old

Answer:

16.33 km

Step-by-step explanation:

The square length of hypotenuse is equal to the sum of two legs' square value:

|HI|^2 + |JI|^2 = |HJ|^2

|HI|^2 + (24.28)^2 = (29.26)^2

|HI|^2 + 589,5184 = 856,1476 (these are full values and will be easier to calculate with a calculator, if not we can use the approximate values: 589,5 and 856,1)

subtract 589,5184 from both sides

|HI|^2 = 266,5636 find the root of boths sides

HI = 16.33 approximately

The base HI of the right triangle is approximately 16.26 km.

Given is a right triangle with perpendicular JI = 24.28 km and hypotenuse HJ = 29.26 km we need to find the base HI.

To find the base HI of the right triangle, we can use the Pythagorean theorem, which states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

Let's denote the base HI as x.

According to the Pythagorean theorem:

HJ² = JI² + HI²

Substituting the given values:

(29.26 km)² = (24.28 km)² + x²

Simplifying the equation:

855.4276 km² = 590.7584 km² + x²

264.6692 km² = x²

To find x, we take the square root of both sides:

x = √(264.6692 km²)

Calculating the value:

x ≈ 16.26 km

Therefore, the base HI of the right triangle is approximately 16.26 km.

If Clovis has spent a total of 123.35 for airline ticket and taxi ,the percent of fare that He tip the taxi driver is At 20%.

A percentage serves as a number or ratio which is been expressed as a fraction of 100.

The amount paid for the airline Ticket and the Taxi is 123.35

Sales Tax on the airline Ticket is 15% of $69, which can be calculated as [tex](15/100 * 69)=10.35[/tex]

The amount without any tip can be calculated as[tex][10.35 +20+69+(2.5*8)][/tex]

To get the amount with the tip, we will substract the from the total amount of airline ticket 123.35 from amount for the tip which is

(123.35-119.35)= 4.

Then we can calculate percentage of the tip as

The answer is  C

- airline ticket: $69

- sales tax, 15%: $10.35

- baggage fee: $20.

- taxi:  8 miles * $2.50 per mile = $20

Sub-total: 69 +10.35 + 20 + 20 =  $ 119.35

If Clovis has spent a total of $123.35 => tip = 123.35 - 119.35 = $4.00

at what percent of his fare did Clovis tip the taxi driver?

[$4 / $20] * 100 = 20%

The perimeter of the land that Tony will fence around the rectangular piece of land that he owns is 56 meters.

The measure of the boundary of the sides of a rectangles called its perimeter. The perimeter of a rectangle is twice the sum its length and width.

[tex]P=2(l+w)[/tex]

Here, (l) is the length of the rectangle and (w) is the width of the rectangle.

The land has an area of 192 m2 and the length is 4m longer than the width. Let suppose the length is l. Thus,

[tex]l=4+w[/tex]

Now the area of rectangle is the product of length and width. Thus,

[tex]A=l\times w\\192=(4+w)\times w\\192=4w+w^2\\w^2+4w-192=0\\w^2+16w-12w-192=0\\w(w+16)-12(w+16)=0\\(w+16)(w-12)=0\\w=-16,12[/tex]

Taking positive side, w=12. The width of the rectangle is 12 m. The length of the rectangle is 4 m longer than the width. Thus, the length of it si 16 m (12+4). Its, perimeter is,

[tex]P=2(16+12)\\P=56\rm\;m[/tex]

Thus, the perimeter of the land that Tony will fence around the rectangular piece of land that he owns is 56 meters.

Step-by-step explanation:

Let O be the centre of the circle. Since P and S are the points of contact of tangents AD and DC respectively, OP ⊥ AD and OS ⊥ DC

Also, AD ⊥ DC (given), therefore, OPDS is a square.

BR = BQ = 27cm...(tangents from an external point to a circle are equal in length)

therefore, CR = CB - BR = (38 - 27)cm = 11cm

SC = CR = 11 cm...(tangents from an external point) therefore, DS = DC - SC = (25 - 11) cm = 14 cm.

therefore,

Radius of a circle = OP = DS = 14 cm...(therefore, OPDS is a square).

Using proportions, it is found that they spent a total of £5.6 for these cartons of apple juice.

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

In this problem, the daily fraction of a carton they drink is given by:

[tex]\frac{1}{3} + \frac{2}{5} = \frac{5 + 6}{15} = \frac{11}{15}[/tex]

Hence, applying the proportion, over 10 days, the amount of cartons they drink is given by:

[tex]10 \times \frac{11}{15} = \frac{110}{15} = 7.33[/tex]

Rounding up, they buy 8 cartons, each at £0.7. Hence the total amount spent is given by:

Examine each term of the polynomial to determine whether it is even, odd, or neither.

Even function → symmetry about the y-axis

Odd function → symmetry about the origin

1) y = x⁴ is an even function, as it has symmetry about the y-axis

y = x² is an even function, as it has symmetry about the y-axis

Therefore, x⁴ + x² is an even polynomial

2) [tex]\sf y=6x^5[/tex] is an odd function, as it has symmetry about the origin.

[tex]\sf y=-x^3[/tex] is an odd function, as it has symmetry about the origin.

Therefore, [tex]\sf y=6x^5-x^3[/tex] is an odd polynomial
