Select all that are equivalent to sin∠GFH
Answer:
I think sin<GEJ IS equivalent to sin∠GFH
All that are equivalent to sin∠GFH is
D) cos(<EGJ)
"Corresponding angles"sin(<GEJ)cos(<FGH)cos(<EGJ)
From the image JE and HF are parallel.
So angle GFH and angle GEJ are corresponding angles.
So they are equal.
so, sin(<GFH) = sin(<GEJ).
From triangle GFH, <GFH+<FGH = 90.
So, sin(<GFH) =cos(<FGH).
Again <FGH = <EGJ.
So, sin(<GFH) =cos(<EGJ)
All that are equivalent to sin∠GFH is cos(<EGJ).
Thus, the correct answer is D.

Mike's car holds 14 2/5 g of gas, averages 20mpg. About how far can Mike's travel if his tank is 1/4 full?
Solution :
It is given that :
The car of Mike's can hold = [tex]$14 \frac{2}{5}$[/tex] g of gas.
[tex]$=\frac{72}{5}$[/tex] g of gas
∴ [tex]$=\frac{1}{4} $[/tex] th of [tex]$\frac{72}{5}$[/tex] g of gas is [tex]$=\frac{1}{4} \times \frac{72}{5}$[/tex]
[tex]$=\frac{18}{5}$[/tex] g of gas
The average distance that the car can travel when the tank is full is = 20 mpg
∴ In [tex]$\frac{72}{5}$[/tex] g of gas, the car travels = 20 mpg
In 1 g of gas, the car travels = [tex]$20 \times \frac{5}{72} $[/tex] mpg
So in [tex]$\frac{18}{5}$[/tex] g of gas, the car travels = [tex]$20 \times \frac{5}{72} \times \frac{18}{5} $[/tex] mpg
= 5 mpg

Describe what the graph and equation look like for each of the parent functions.
Answer:
there you go there's your answers
Step-by-step explanation:
→A parent function is the simplest function of a family of functions. of this form is y = x2. The simplest parabola is y = x2, whose graph is shown at the right. The graph passes through the origin (0,0), and is contained in Quadrants I and II.
€xample→For example, you can simplify "y=2*sin(x+2)" to "y=sin(x)" or "y=|3x+2|" to "y=|x|." Graph the result. This is the parent function. For example, the parent function for "y=x^+x+1" is just "y=x^2," also known as the quadratic function.

Choose ALL the angles with a measure less that 90 degrees.
Answer:
Top left Top middle Bottom Left Bottom right
Step-by-step explanation
If the angle makes an "L" it is a 90 degrees angle or a right angle
If the angle makes a "V" it is less than 90 degrees or an acute angle
If the angle makes a "Stretched out V" it is more than 90 degrees or an obtuse angle
The option that represents the acute angle will be option A, option B, option D, and option F.
What is an angle?The inclination is the separation seen between planes or vectors that meet. Degrees are another way to indicate the slope. For a full rotation, the angle is 360°.
The types of angles are as follows:
If the angle is less than 90° then the angle is known as an acute angle.If the angle is equal to 90° then the angle is known as a right angle.If the angle is more than 90° then the angle is known as an obtuse angle.Then the option that represents the acute angle will be option A, option B, option D, and option F.

An eagle is flying at an altitude of 280 feet. The angle of depression from the eagle to a mouse on the ground is 15º. What is the direct line distance from the eagle to the mouse? Round answer to the nearest thousandth
Answer:
Step-by-step explanation:
X = distance between eagle and mouse.
sin(15°) = 280/x
X = 280/sin(15°) = 1,081.837 ft
What is the value of x? 5 + 1/5x = 5
Answer:
x = 0
Step-by-step explanation:
5 + 1/5x = 5
Subtract 5 from both sides.
1/5x = 0
Divide both sides by 1/5
x = 0

Por un tubo de 2.5 cm de diámetro fluye agua con una repidez de 20 cm/s ¿Cuál es el valor del flujo y el gasto del agua?
Answer:
El flujo y gasto de agua es aproximadamente 98.175 centímetros cúbicos por segundo.
Step-by-step explanation:
El gasto del agua ([tex]Q[/tex]), medido en centímetros cúbicos por segundo, es el flujo que pasa a través del tubo. La ecuación para determinar el gasto es:
[tex]Q = \frac{\pi}{4}\cdot D^{2}\cdot v[/tex] (1)
Donde:
[tex]D[/tex] - Diámetro del tubo, medido en centímetros.
[tex]v[/tex] - Velocidad del flujo, medida en centímetros por segundo.
Si sabemos que [tex]D = 2.5\,cm[/tex] y [tex]v = 20\,\frac{cm}{s}[/tex], entonces el flujo y gasto del agua es:
[tex]Q = \frac{\pi}{4}\cdot (2.5\,cm)^{2}\cdot \left(20\,\frac{cm}{s} \right)[/tex]
[tex]Q \approx 98.175\,\frac{cm^{3}}{s}[/tex]
El flujo y gasto de agua es aproximadamente 98.175 centímetros cúbicos por segundo.

Answer:
Traduzca el resto en inglés
Step-by-step explanation:
Simplificando
6x + -2 + 2x = -2 + 4x + 8
Reordenar los términos:
-2 + 6x + 2x = -2 + 4x + 8
Combinar términos semejantes: 6x + 2x = 8x
-2 + 8x = -2 + 4x + 8
Reordenar los términos:
-2 + 8x = -2 + 8 + 4x
Combinar términos semejantes: -2 + 8 = 6
-2 + 8x = 6 + 4x
Solving
-2 + 8x = 6 + 4x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-4x' to each side of the equation.
-2 + 8x + -4x = 6 + 4x + -4x
Combine like terms: 8x + -4x = 4x
-2 + 4x = 6 + 4x + -4x
Combine like terms: 4x + -4x = 0
-2 + 4x = 6 + 0
-2 + 4x = 6
Add '2' to each side of the equation.
-2 + 2 + 4x = 6 + 2
Combine like terms: -2 + 2 = 0
0 + 4x = 6 + 2
4x = 6 + 2
Combine like terms: 6 + 2 = 8
4x = 8
Divide each side by '4'.
x = 2
Simplifying
x = 2
