Mathematics
1 answer:
Ksivusya [100]2 years ago

Answer:

Reflecting a point across the y-axis -> changes the sign of the x-coordinate

Reflecting a point across both axes -> changes the sign of both coordinates

Reflecting a point across the x-axis -> changes the sign of the y-coordinate

Step-by-step explanation:

Reflections:

  1. The rule to reflect a point across the y-axis is (-x, y), meaning that the x-coordinate's sign changes.
  2. Reflecting a point across both axes is the same thing as rotating it 180 degrees, so the rule is (-x, -y). This means that both coordinates' signs change.
  3. Reflecting a point across the x-axis is (x, -y), meaning that the y-coordinate's sign changes.

Answer:

$16.2

Step-by-step explanation:

15 x .08 [wonder how i got .08? 8% = 0.8]

= 1.2

here's where most people mess up, they usually forget to add the tax to the original cost.

15 + 1.2=

If s(x)=x-7 and t(x) =4x^2+3 which expression is equivalent to (t×s)(x)​
marshall27 [118]

Answer:

\large\boxed{(t\times s)(x)=4x^3-28x^2+3x-21}

Step-by-step explanation:

s(x)=x-7\\t(x)=4x^2+3\\\\(t\times s)(x)=t(x)\times s(x)\\\\\text{Substitute:}\\\\(t\times s)(x)=(4x^2+3)(x-7)\\\\\text{use FOIL:}\ (a+b)(c+d)=ac+ad+bc+bd\\\\(t\times s)(x)=(4x^2)(x)+(4x^2)(-7)+(3)(x)+(3)(-7)\\\\=4x^3-28x^2+3x-21

Solve the system by the elimination method.
Vika [28.1K]
10x + 2y - 6 = 0

Multiply 5x + y - 3 = 0 by 2

2(5x + y - 3 = 0) = 10x + 2y - 6 = 0

A strobe light is located at the center of a square dance room. the rotating light is 40 feet from each of the square walls and
Effectus [21]

The equation of the rotating light is an illustration of a secant function

The equation that represents the distance between the center of the circle and the light source is d(t) = 40\sec(\frac{\pi}{3}t)

<h3>How to determine the equation</h3>

The equation is a secant function represented by

y =A\sec(Bt)

Where:

A represents the amplitude

So, we have:

A = 40 --- the distance of the light from each square wall

B represents the period, and it is calculated as:

B = \frac{2\pi}{T}

The light completes its full rotation every 6 seconds.

This means that,

T = 6

So, we have:

B = \frac{2\pi}{6}

Simplify

B = \frac{\pi}{3}

Substitute values for A and B in y =A\sec(Bt)

y = 40\sec(\frac{\pi}{3}t)

Rewrite as a function

d(t) = 40\sec(\frac{\pi}{3}t)

Hence, the equation that represents the distance between the center of the circle and the light source is d(t) = 40\sec(\frac{\pi}{3}t)

How do I find the area
inn [45]
Wasssaa,

Steps:

To find the area of a triangle you multiply the base times the height, in this case the is (19m)
and the height is (11m), after you multipy those numbers you divide by (2)
(19m \times 11m) \div 2
\frac{209  }{2}

Answer:
104.5sq \: m
