alexgriva [62]

Responder:

La temperatura bajó 12 °

Explicación paso a paso:

Dado que:

Temperatura en la noche = + 2 ° (2

Temperatura de la mañana = - 12 (12 ° bajo cero).

La diferencia de temperatura entre la noche y la madrugada:

Temperatura nocturna - temperatura por la mañana temprano

2 - (-12)

2 + 12 = 14

Hay una diferencia de temperatura de 12 °. La temperatura bajó 12 ° entre la noche y la madrugada.

The expression's 30^2-150x-60 and (5x-20)(6x+3) define the same function, f.

Lena [83]

Answer:

$30x^{2} -105x+60$

Step-by-step explanation:

I just solved it.

(5x-20)(6x+3)

5x•6x=30x^2

5x•3=15x

-20•6x=-120x

-20•3=-60

R is the first quadrant region enclosed by the x-axis and the curve y = 2x + b, and the line x = b, where b > 0. Find the val

Elis [28]

The area of $R$ is given by the integral

$\displaystyle\int_0^b(2x+b)\,\mathrm dx=288$

Integrating yields

$(x^2+bx)\bigg|_{x=0}^{x=b}=(b^2+b^2)-(0+0)=2b^2$

So you have

$2b^2=288\implies b^2=144\impiles b=12$

I need help with trigonometry

Answer:

In alphabetic order:

x can be found with pythagorean theorem, since triangle ADC is right in D.

$x= \sqrt {7^2-2.2^2} \approx 6.6$

y and z are 7 times respectively the sine and cosine of angle ACB.

$y= 7sin\ 52\° \approx 5.5\\z=7 cos\ 52\° \approx 4.3$

Finally, $\theta$ can be calculated by determining the arc sine (or inverse sine) of the ratio CD over AC

$\theta = sin^{-1} (\frac{2.2}7) \approx 18.3\°$
