Answer:

40 degrees

Given sin theta= 6/11 and sec theta < 0, find cos theta and tan theta.

bekas [8.4K]

Answer: option a.

Step-by-step explanation:

By definition, we know that:

$cos^2(\theta)=1-sen^2(\theta)\\\\tan(\theta)=\frac{sin(\theta)}{cos(\theta)}$

Substitute $sin(\theta)=\frac{6}{11}$ into the first equation, solve for the cosine and simplify. Then, you obtain:

$cos(\theta)=\±\sqrt{1-(\frac{6}{11})^2}\\\\cos(\theta)=\±\sqrt{\frac{85}{121}}\\\\ cos(\theta)=\±\frac{\sqrt{85}}{11}$

As $sec\theta$ then $cos\theta$ :

$cos(\theta)=-\frac{\sqrt{85}}{11}$

Now we can find $tan\theta$ :

$tan\theta=\frac{\frac{6}{11}}{-\frac{\sqrt{85}}{11}}\\\\tan\theta=-\frac{6\sqrt{85}}{85}$

Merideth measured 3.25 cups of flour and 1.625 cups of brown sugar into

Fiesta28 [93]

Answer:

Step-by-step explanation:

This is just an addition question. If you have a calculator just add the numbers.

3.25 + 1.625 = 4.875 cups in the bowl.

Sometimes you can use another method. Sometimes it is shorter.

3 1/4 + 1 5/8 = 3 2/8 + 1 5/8 = 4 7/8.

7/8 = 0.875

A woman is walking at the rate of 90 yards per minute. How fast is she going in feet per second?

motikmotik

Answer:

She is going at the rate of 4.5 feet per second.

Step-by-step explanation:

Given:

The rate of walking is 90 yards per minute.

Now, to find the rate in feet per second.

1 yard = 3 foot.

1 minute = 60 seconds.

So, first we find the rate of walking per second in yard = $90\div 60$

Therefore by dividing we get = $1.5 yard$

Now, we find the rate of walking per second in feet = $1.5\times 3$

So, by multiplying we get = $4.5 feet$

Therefore, she is going at the rate of 4.5 feet per second.
