lana [24]

Answer:

B. sen α = BC/b

Step-by-step explanation:

Las identidades trigonométricas se utilizan para resolver problemas de ángulos rectos.

En un ángulo recto, el lado al que se hace referencia como opuesto es el lado opuesto al ángulo, el lado al que se hace referencia como adyacente es el lado siguiente al ángulo (entre el ángulo y el ángulo recto) mientras que la hipotenusa es el lado más largo (opuesto al ángulo recto)

De identidades trigonométricas:

$sen\ \alpha=\frac{lado\ opuesto}{hipotenusa} \\\\lado\ opuesto=BC=a\\\\hipotenusa=b\\\\sen\ \alpha=\frac{lado\ opuesto}{hipotenusa} =\frac{BC}{b} \\\\sen\ \alpha =\frac{BC}{b}$

Vinil7 [7]

Answer:

250 turkey sandwiches were delivered.

There were 230 roast beef delivered.

115 PB&J were delivered.

Step-by-step explanation:

This question is solved using a system of equations.

I am going to say that:

x is the number of turkey sandwiches.

y is the number of roast beef.

z is the number of PB&J.

Donnie delivered 595 box lunches

This means that $x + y + z = 595$

There were 20 more turkey sandwiches then roast beef.

This means that $x = y + 20$

There were twice as many roast beef has PB&J.

This means that $y = 2z$ .

So in the second equation, we have that $x = 2z + 20$

Replacing this in the first equation:

$x + y + z = 595$

$2z + 20 + 2z + z = 595$

$5z = 575$

$z = \frac{575}{5}$

$z = 115$

115 PB&J were delivered.

$x = 2z + 20 = 2*115 + 20 = 250$

250 turkey sandwiches were delivered.

$x = y + 20$

$y = x - 20 = 250 - 20 = 230$

There were 230 roast beef delivered.

Alex Ar [27]

The answer to this question is letter C) By segment addition, DC plus BD is equal to BC. Point D is located at the middle of segment BC. Therefore BC is just equal to BD plus DC.

<span>Now we can prove BC2 = BA2+CA2 by using the Pythagorean theorem.</span>

Determine the amplitude of the function y=-1/2cosx

OLEGan [10]

Use the form a cos(bx-c) +d to find the variables used to find the amplitude, period, phase shift and vertical shift.

a would be the amplitude and is the number before cos.

In the given formula -1/2 is before cos, so the amplitude would be the positive value which would be 1/2
