(x, y) → (–y, x)




(x, y) → (y, –x)

Answer:

5

Step-by-step explanation:

So we want to find the value of x where the area to the left of it is equal to 0.6.

Let's start by finding the area of the first triangle, between x=0 and x=4.

A = 1/2 bh

A = 1/2 (4) (0.2)

A = 0.4

So we know a > 4.  What if we add the area of that rectangle?

A = 0.4 + bh

A = 0.4 + (1) (0.2)

A = 0.6

Aha!  So a = 5.

Answer:

The slant height of the pyramid is 3√2 ft, or to the nearest tenth ft,

4.2 ft

Step-by-step explanation:

The equation for the volume of a pyramid of base area B and height h is

V = (1/3)·B·h.  Here, V = 432 ft³, B = (12 ft)² and h (height of the pyramid) is unknown.  First we find the height of this pyramid, and then the slant height.

V = 432 ft³ = (144 ft²)·h, so h = (432 ft³) / (144 ft²) = 3 ft.

Now to find the slant height of this pyramid:  That height is the length of the hypotenuse of a right triangle whose base length is half of 12 ft, that is, the base length is 6 ft, and the height is 3 ft (as found above).

Then hyp² = (3 ft)(6 ft) = 18 ft², and the hyp (which is also the desired slant height) is hyp = √18, or √9√2, or 3√2 ft.

The slant height of the pyramid is 3√2 ft, or to the nearest tenth ft,

4.2 ft

Answer:

the net change would be 22.50!

Step-by-step explanation:

add 4.50 5 times!

Answer:

The net change to Ian’s account after the utility company lives up to the agreement will be $22.50.

Step-by-step explanation:

The utility company made a mistake on Ian’s electric bill.

The company has agreed to credit Ian’s account for five transactions, each worth $4.50

This gives [tex]4.50\times5=22.50[/tex] dollars

So, the net change to Ian’s account after the utility company lives up to the agreement will be $22.50.

Answer:

A. x < 6 and x > - 28

Step-by-step explanation:

We have been given the following inequality;

| x+11 | < 17

We can replace the absolute value function by re-writing the inequality as;

-17< x+11<17

subtract 11 from both sides;

-17-11<x+11-11<17-11

-28<x<6

splitting this we have;

x<6

x>-28

Answer:

A. x < 6 and x > - 28

Step-by-step explanation:

| x+11 |< 17

x + 11 < 17

x < 6

-(x + 11) < 17

-x - 11 < 17

-x < 28

x > - 28

Answer

6 > x > -28 (x < 6 and x > - 28)

The mass of the gasoline in the container is 2657.81grams

The ratio of the mass of an object to its volume is its density. Mathematically;

Density = Mass/Volume

Mass = density * volume

Given the following

Density =  750 kg/m³.

Determine the volume

Volume = πr²h
Volume =3.14(0.75)² * 2

Volume = 3.54375 m³

Determine the mass

Mass = 750 * 3.54375

Mass = 2657.81grams

Hence the mass of the gasoline in the container is 2657.81grams

The expression for the perimeter of a rectangle with length (3x-8) cm and width (2x-7) cm is P = 2 * ((3x - 8) + (2x - 7)). After simplification, the final expression for the perimeter is P = 10x - 30 cm.

The perimeter of a rectangle is given by the formula 2 * (length + width). Here, the length of the rectangle is given as (3x - 8) cm and the width is given as (2x -7) cm. Therefore, substituting these into the formula the expression for the perimeter (P) is P = 2 * ((3x - 8) + (2x - 7)).

To simplify this, we first add up the like terms within the parentheses giving us P = 2 * (5x - 15). Then, apply the distributive property of multiplication over addition to simplify further and we get P = 10x - 30 cm. This is the simplified expression for the perimeter of the rectangle.

The following integers from the greatest to least are as follows:

+3, 0, -3, -2, -8

The answer is +3,0,-2,-3,-8

Answer:

x=4

Step-by-step explanation:

Simplifying

4x + 16 + -1x = 22 + 6

Reorder the terms:

16 + 4x + -1x = 22 + 6

Combine like terms: 4x + -1x = 3x

16 + 3x = 22 + 6

Combine like terms: 22 + 6 = 28

16 + 3x = 28

Solving

16 + 3x = 28

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-16' to each side of the equation.

16 + -16 + 3x = 28 + -16

Combine like terms: 16 + -16 = 0

0 + 3x = 28 + -16

3x = 28 + -16

Combine like terms: 28 + -16 = 12

3x = 12

Divide each side by '3'.

x = 4

Simplifying

x = 4

Hope this helps! And please correct me if I'm wrong so others can have the correct answer.

For this case we must solve the following equation:

[tex]4x + 16-x = 22 +6[/tex]

We add similar terms on both sides of equality:

[tex]3x + 16 = 28[/tex]

We subtract 16 from both sides of the equation:

[tex]3x = 28-16\\3x = 12[/tex]

We divide between 3 on both sides of the equation:

[tex]x = \frac {12} {3}\\x = 4[/tex]

Answer:

y = 57, PQ = 60, RS = 28

Last option is the answer

Step-by-step explanation:

3 * y = 9 * 19

3y = 171

y = 57

PQ = 3 + 57 = 60

RS = 9 + 19 = 28

Answer:

y = 57; PQ = 60; RS = 28

Step-by-step explanation:

The product of lengths of parts of a chord is a constant, so ...

PT·TQ = RT·TS

TQ = y = RT·TS/PT = 9·19/3 = 57

Of course the total chord length is the sum of its parts, so ...

PQ = PT +TQ = 3 +57 = 60

RS = RT +TS = 9 +19 = 28

Then your answer choice is ...

y = 57; PQ = 60; RS = 28.

Answer:

C

Step-by-step explanation:

49x² + 28xy + 4y² ← is a perfect square of the form

(ax + by)² = a²x² + 2abxy + b²y²

49 = 7² ⇒ a = 7 and 4 = 2² ⇒ b = 2

2ab = 2 × 7 × 2 = 28

Hence

49x² + 28xy + 4y² = (7x + 2y)²

with factor 7x + 2y ⇒ C

Answer:

Both a and b are independent (see explanation)

Step-by-step explanation:

Events A and B are independent when

[tex]P(A\cap B)=P(A)\cdot P(B)[/tex]

a) A - "winning"

From the table,

[tex]P(A)=0.25\\ \\P(B)=0.8\\ \\P(A\cap B)=0.2[/tex]

Since

[tex]0.25\cdot 0.8=0.2[/tex]

events are independent.

b) A - "losing"

B - "playing away"

From the table,

[tex]P(A)=0.75\\ \\P(B)=0.2\\ \\P(A\cap B)=0.15[/tex]

Answer: Third Option

[tex]y = -10x + 110[/tex]

Step-by-step explanation:

The equation of a line in the pending intersection form has the following form:

[tex]y=mx +b[/tex]

Where m is the slope of the line and b is the intersection with the y axis.

Observe in the graph that the data form a decreasing line. Then the adjustment line must have a negative slope [tex]m <0[/tex].

The first and the second option have positive slopes, therefore we discard them.

Notice in the scatter diagram that the intersection of the line with the y-axis (x = 0) is above 90.

The line of the fourth option has a value of [tex]b = -110 <90[/tex].

Therefore the line that best fits the data is the third option

[tex]y = -10x + 110[/tex]

Note that the line has a slope [tex]m = -10[/tex] and a value of [tex]b> 90[/tex]

Answer:

Richard, at 2/3, versus Cooper, at 5/8

Step-by-step explanation:                              12 min

Richard's ratio of cardio to resistance is  R = ------------ = 2/3

                                                                            18 min

                            10 min

Cooper's is  C = ------------ = 5/8

                            16 min

The LCD here is 24.  Rewrite 2/3 and 5/8 with denominator 24 for greater ease in comparing the two fractions/ratios:

R = 16/24 and C = 15/24

So it becomes obvious that Richard does a higher ratio of carido to resistance.

Angles TOS and ROQ are congruent, so [tex]m\angle ROQ=m\widehat{RQ}=28^\circ[/tex].

[tex]m\angle ROQ+m\angle QOP+m\angle POT=180^\circ\implies m\angle QOP=62^\circ[/tex]

The measure of arc RPS = [tex]208^{\circ}$$[/tex].

The measure of an inscribed angle is half the measure of the intercepted arc.

(The measure of the arc is twice the measure of the angle)

Arc length is a measurement of distance, so it cannot be in radians.

Angles TOS and ROQ are congruent,

so [tex]$m \angle R O Q=m \widehat{R Q}=28^{\circ}$[/tex].

RT is the diameter of the circle,

so [tex]$m \widehat{R T}=180^{\circ}$[/tex], and in particular [tex]$m \angle R O Q+m \angle Q O P+m \angle P O T=180^{\circ}[/tex]

[tex]\Longrightarrow m \angle Q O P=62^{\circ}$[/tex]

Then

[tex]$$m \widehat{R P S}=28^{\circ}+62^{\circ}+90^{\circ}+28^{\circ}=208^{\circ}$$[/tex]

[tex]$$m \widehat{R P S}=208^{\circ}$$[/tex]
