The temperature at 9 am was -11 degrees.

We know that at 5 am, it was -7 degrees. Since the change of temperature is a negative number, then we subtract the absolute value of the change from -7. -7 - 3 = -10. Following this pattern, we then have:
-10 - 2 = -12 (6 am - 7 am)
-12 - 5 = -17 (7 am - 8 am)
-17 + 6 = -11 (8 am - 9 am, added since it was a positive change of temperature)

And our final answer is -11 degrees Fahrenheit.

If the mountain at a convergent plate boundary is growing at a rate of 1.6 mm per year, how much higher will it be in 50 years ?

Mrrafil [7]

The mountain will be at 80mm long in 50 years because 50 times 1.6mm equals 80

Assume that the terminal side of thetaθ passes through the point (negative 12 comma 5 )(−12,5) and find the values of trigonomet

zmey [24]

Answer:

$\sin \theta = \dfrac{5}{13}$ and $\sec \theta = -\dfrac{13}{12}$

Step-by-step explanation:

Assume that the terminal side of thetaθ passes through the point (−12,5).

In ordered pair (-12,5), x-intercept is negative and y-intercept is positive. It means the point lies in 2nd quadrant.

Using Pythagoras theorem:

$hypotenuse^2=perpendicular^2+base^2$

$hypotenuse^2=(5)^2+(12)^2$

$hypotenuse^2=25+144$

$hypotenuse^2=169$

Taking square root on both sides.

$hypotenuse=13$

In a right angled triangle

$\sin \theta = \dfrac{opposite}{hypotenuse}$

$\sin \theta = \dfrac{5}{13}$

$\sec \theta = \dfrac{hypotenuse}{adjacent}$

$\sec \theta = \dfrac{13}{12}$

In second quadrant only sine and cosecant are positive.

$\sin \theta = \dfrac{5}{13}$ and $\sec \theta = -\dfrac{13}{12}$

What is the answer to 7f/11 =7/11

serious [3.7K]

So,

$\frac{7f}{11} = \frac{7}{11}$

Multiply both sides by 11.
$7f = 7$

Divide both sides by 7.
f = 1

Check.
$\frac{7(1)}{11} = \frac{7}{11}$
$\frac{7}{11} = \frac{7}{11}$ This checks.

S = {1}
