x=83

Step-by-step explanation:

Given:

The function f(x) describes the amount of money, in dollars, the club will earn for wrapping x presents.

[tex]f(x)=3x[/tex]

To find:

The f(658).

Solution:

We have,

[tex]f(x)=3x[/tex]

Substitute x=658 to find the value of f(658).

[tex]f(658)=3(658)[/tex]

[tex]f(658)=1974[/tex]

It means, the club will earn $1974 for wrapping 658 presents.

Therefore, [tex]f(658)=1974[/tex].

The measure of m<LKT from the figure is 35 degrees

Line tangential to a circle is at 90 degrees to the circle.

Given the following parameter

m<TLK = 55 degrees

According to the theorem above:

m<TLK + m<LKT = 90

m<LKT = 90- m<TLK
m<LKT = 90 -55

m<LKT  = 35 degrees

Hence the measure of m<LKT from the figure is 35 degrees

Answer:

18 inches

Step-by-step explanation:

It would be 18 inches because if 2 inches represent 25 miles and 225 divided by 25 is 9 that would mean 18 inches would be 225 because instead of it being 25*18=225 which it doesn't it would be 12.5*18=225 which is true

The number of times the hydrogen ion concentration of Aeen’s drink is the hydrogen ion concentration of Marien’s drink is 4 approx.

The phrase "times bigger" shows this:

If a number 'x' is 't' times bigger than 'y', then that means:

[tex]x = t \times y[/tex]

It is because 'y' had to multiply itself with 't' to get in equal level of 'x'

A solution with 'x' as its pH contains [tex]10^{-x} mol/L[/tex] of hydrogen ions.

For the considered case, we have:

Thus, its hydrogen ion concentration is [tex]10^{-2.7}[/tex] = x (say)

Thus, its hydrogen ion concentration is [tex]10^{-3.3}[/tex] = y (say)

Then, let x is t times bigger than y, then that means:

[tex]x = t\times y\\\\t = \dfrac{x}{y} = \dfrac{10^{-2.7}}{10^{-3.3}} = 10^{-2.7 - (-3.3)} = 10^{-0.6} \approx 4[/tex]

It is because of the property [tex]a^b \times a^c = a^{b+c}[/tex]

Thus, hydrogen ion concentration of Marien's drink is approx 4 times the hydrogen ion concentration of Aeen's drink.

9514 1404 393

Answer:

Step-by-step explanation:

1. The common difference is -4, which matches recursive relation A.

2. Signs alternate, so the common ratio must be negative, matching recursive relation C.

3. The common difference is 0, and the common ratio is 1, so both relations B and D are a match.

_____

An arithmetic sequence with common difference d can be described by the recursive relation ...

  f(n) = f(n-1) +d

A geometric sequence with common ratio r can be described by the recursive relation ...

  f(n) = r·f(n-1)

One typically has to look at only the first three terms to determine if they have a constant difference or a constant ratio.

Answer:

c, d, and h are parallel

Step-by-step explanation:

parallel lines are when the slope is the same and the y-intercept is different

a. y = 2x - 3

b. y = -3x + 7

c. y = -2x + 4

d. y = -2x + 2

e. y = 1/3x - 3

f. y = x/2 + 7/2

g. y = -x/3 + 8/3

h. y = -2x + 5

c, d, and h all have the same slope of -2 and contain different y-intercepts

The percent Jan’s total grocery bill discounted when she bought no items on sale is 16.65%.

Percentage of a number is the part of the number expressed in the in every hundred. Percentage of a number is expressed with the symbol '%'.

Jan went grocery shopping and only bought items which had been marked down.

The items she bought, along with their prices, can be seen below.

Total price of the items is $18.72. Now find out the original price using the above formula for each of the item. The sum of original price of all the items will be $22.46.

Thus, the discounted price will be,

[tex]P_d=\dfrac{18.72}{22.46}\times100\\P_d=83.35\%[/tex]

The overall markdown is,

[tex]\rm Markdown=100-18.35\\\rm Markdown=16.65\%[/tex]

Answer:

a = 8/3b or b = 3/8a

Step-by-step explanation:

The fractions present in the table, 24/9 and 40/15, are equivalent to 8/3, showing a linear relationship between the variables a and b. Knowing this, reducing any of the 3 fractions to its lowest form will allow you to find the information necessary to develop an equation. As 8/3 turns out to be the simplest form of any of the fractions, the equation is a = 8/3b, or, if you decide to reverse the variables, b = 3/8a.

so for the first question its answer is 763.02 in and for the second one its 1,526.04

Step-by-step explanation:

1.

V = π r^2h

π = 3.14

V = 3.14 x 9^2 x 3

V= 3.14 x 81 x 3

V = 3.14 x 243

V = 763.02 in

2.

So we already know that 9^2 is 81 and that double 3 is 6

V = 3.14 x 81 x 6

V = 3.14 x 486

V = 3.14 x 486

V = 1,526.04 in

Answer:

Tanya is correct.

Step-by-step explanation:

a). Tanya has the equation,

   x - 2 = 2x - 4

   x - 2x = 2 - 4

  -x = -2

   x = 2

  By adding (x + 2) on both the sides of the equation,

  (x - 2) + (x + 2) = (2x - 4) + (x + 2)

  2x = 3x - 2

  2x - 3x = -2

  x = 2

Tanya is correct.

b). By Diego's statement

   (x - 2)(x + 2) = (2x - 4)(x + 2)

   x² - 4 = 2x²- 8

   x² - 2x² = 4 - 8

   -x² = -4

    x² = 4

    x = ±2

 Therefore, Diego's statement is incorrect.

======================================================

Explanation:

The x coordinates of the two points are -6 and 4. They add to -6+4 = -2. Cut this in half to get -2/2 = -1.

The y coordinates of the two points are 3 and 9. They add to 3+9 = 12. Cut this in half to get 12/2 = 6.

The midpoint formula is

[tex]\left(x_m, y_m) = \left(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}\right)[/tex]

In short, you add the corresponding coordinates and then divide by 2.

Answer:

X=1, y=6

Step-by-step explanation:

Let's solve your system by substitution.

−8x−2y=−20;x+2y=13

Rewrite equations:

x+2y=13;−8x−2y=−20

Step: Solvex+2y=13for x:

x+2y=13

x+2y+−2y=13+−2y(Add -2y to both sides)

x=−2y+13

Step: Substitute−2y+13forxin−8x−2y=−20:

−8x−2y=−20

−8(−2y+13)−2y=−20

14y−104=−20(Simplify both sides of the equation)

14y−104+104=−20+104(Add 104 to both sides)

14y=84

Answer:

Perpendicular

Step-by-step explanation:

Remember that:

So, let's find the slope of QR and ST.

QR)

We can use the slope formula:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Let Q(-6, 11) be (x₁, y₁) and R(2, -1) be (x₂, y₂). Substitute:

[tex]m=\frac{-1-11}{2-(-6)}[/tex]

Subtract:

[tex]m=-12/8=-3/2[/tex]

So, the slope of QR is -3/2.

ST)

Let S(-4, 8) be (x₁, y₁) and T(-1, 10) be (x₂, y₂). Substitute:

[tex]m=\frac{10-8}{-1-(-4)}[/tex]

Subtract:

[tex]m=2/3[/tex]

So, the slope of ST is 2/3.

The negative reciprocal of -3/2 is 2/3.

And the negative reciprocal of 2/3 is -3/2.

So, the slopes are indeed negative reciprocals of each other.

So, QR and ST are perpendicular.
