The inequality that represents this situation is x ≤ 6. On the other hand, the parents can ship only the tennis rackets.

The equality that represents this situation is x ≤ 6 because the number of pounds that can be added (x) has to be 6 or less than 6.

The parents can only ship the tennis rackets because these are 5 pounds which meets the criteria of the inequality.

The inequality would change to x ≤ 1 because the weight that could be added if he needs these producs changes to only 1 pound.

 ➪ First, subtract 5 on both sides:-

-3x=-10-5

 ❒ Which simplifies to:-

 ✩ -3x=-15

Divide by -3 on both sides:-

   ✩  x=5

An inscribed angle (like angle RTS) is half its intercepted arc.

Angle RTS = 51

Then, we just have a triangle to look at. Remember that the interior angles of a triangle add up to 180.

67 + 51 + x = 180

118 + x = 180

x = 62

Answer: angle RST = 62 degrees

Hope this helps!

Answer:

x = 9

Step-by-step explanation:

Answer:

answer C.

Step-by-step explanation:

the base of the triangle is 4 units.the other leg is sqrt5.

the last leg is 4 +9 = 13 so it is sqrt 13.

add them all up together and you get 4+sqrt 13 + sqrt 5 which is C.

Step-by-step explanation:

How do you tell if a relation is a function using domain and range?

Find the domain by listing all the x values from the relation. Find the range by listing all the y values from the ordered pairs. Repeated values within the domain or range don't have to be listed more than once. In order for a relation to be a function, each x must correspond with only one y value.

which means

There is not a function

Answer:

  1206.4 ft³

Step-by-step explanation:

The volume of the composite figure is the sum of the volumes of its parts. Each part has its own volume formula.

__

The formula for the volume of a cone is ...

  V = 1/3Bh . . . . where B is the area of the base, and h is the height

The formula for the volume of a cylinder is ...

  V = Bh . . . . where B is the area of the base, and h is the height

The formula for the area of a circle is ...

  A = πr² = π(d/2)² = (π/4)d²

Combining the volume formulas for a figure with the same base area, we have ...

  V = B(cylinder height) + 1/3B(cone height)

  V = B(cylinder height + 1/3×cone height) . . . . where B is the base area

Using 16 ft for the diameter, and 4 ft and 6 ft for the heights of the cylinder and cone, respectively, we have ...

  V = (π/4)(16 ft)²(4 ft + 1/3×6 ft) = 64π(4 +2) ft³ = 384π ft³

The volume is about ...

  384π ft³ ≈ 1206.4 ft³

The expressions which represents the slope of a tangent to the curve [tex]y=\frac{1}{x+1}[/tex] at any point (x, y) are:

                                ​[tex]f'(x) =limh \rightarrow 0\frac{-h}{h(x+1)(x+h+1)}\\\\f'(x) =limh \rightarrow 0\frac{-h}{x^2h+2xh+xh^2+h^2 +1}[/tex]

Mathematically, the slope of a tangent line to the curve is given by this equation:

[tex]f'(x) =limh \rightarrow 0\frac{f(x+h)-f(x)}{h}[/tex]

Given the function:

[tex]f(x)=y=\frac{1}{x+1}[/tex]

When (x + h), we have:

[tex]f(x+h)=y=\frac{1}{x+h+1}[/tex]

Next, we would find the derivative of f(x):

[tex]f'(x) =limh \rightarrow 0\frac{\frac{1}{x+h+1} -\frac{1}{x+1}}{h}\\\\f'(x) =limh \rightarrow 0\frac{x+1 -(x+h+1)}{h(x+1)(x+h+1)}\\\\f'(x) =limh \rightarrow 0\frac{x+1 -x-h-1}{h(x+1)(x+h+1)}\\\\f'(x) =limh \rightarrow 0\frac{-h}{h(x+1)(x+h+1)}\\\\f'(x) =limh \rightarrow 0\frac{-h}{x^2h+2xh+xh^2+h^2 +1}\\\\f'(x) = \frac{-1}{(x+1)(x+1)} \\\\f'(x) = \frac{-1}{(x+1)^2}[/tex]

Answer:

To solve this question, you simply apply algebraic formulas to geometric relationships.

The perimeter is simply the sum of the lengths of the sides of a shape. However, in this case, there is an "x" involved, so you must add algebraically.

Simply add the length of the sides up.

[3x] + [6x-2] + [x+3] + [4x+1] + [5x-2] = Perimeter

Now, simplify. Since adding is commutative, you can simply put all the variables first and constants next, no matter where they come from within the expression.

3x + 6x + x + 4x + 5x + -2 + 3 + 1 + -2

19x + 0 (-2-2 + 3+1 cancel out)

The perimeter of this pentagon is 19x.

an account transaction log is simply a sequence of basic additions and subtractions.

he made a mistake in line 4 : $180 - $188 = -$8 and not $8.

he missed that this was going below zero and needed a "-" sign.

from there on everything else is wrong too (although the individual calculations are correct) - the balances are off by $16 (2×8 from -8 to +8) :

+$20 gave the real balance of $12 and not $28.

-$5.95 gave the real balance of $6.05 and not $22.05.

Answer:

[tex]a_{20}[/tex] = 84

Step-by-step explanation:

[tex]a_{n}[/tex] = [tex]a_{1}[/tex] + ( n - 1 )d

~~~~~~~~~~~~~

[tex]a_{5}[/tex] = [tex]a_{1}[/tex] + (5 - 1)d = 24

[tex]a_{9}[/tex] = [tex]a_{1}[/tex] + (9 - 1)d = 40

[tex]a_{1}[/tex] + 4d = 24 ........... (1)

[tex]a_{1}[/tex] + 8d = 40 ........... (2)

(2) - (1)

4d = 16 ⇒ d = 4

[tex]a_{1}[/tex] + 8(4) = 40 ⇒ [tex]a_{1}[/tex] = 8

[tex]a_{20}[/tex] = 8 + ( 20 - 1 ) × 4 = 84

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

Reason:

If the linear scale factor is 5, then the volume scale factor is 5^3 = 125

Meaning we'll multiply the old volume by 125 to get the new volume

new volume = 125*(old volume)

new volume = 125*(24)

new volume = 3000

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

A more in-depth look:

Consider a 2 by 2 by 2 block. Its volume is 2*2*2 = 8

Now multiply each dimension by 5, so we now have a 10 by 10 by 10 block. The new larger volume is 10*10*10 = 1000

The volume ratio is 1000/8 = 125, which matches with the value found earlier.

Since we multiplied each piece by 5, and did so three times, we're really multiplying the volume by 5*5*5 = 125.
