Which graph represents the reflection in the x-axis of the curve y = cos x
Ber [7]

Answer:

The curve represented by Green color Dotted Lines in the attached figure represents the Reflection in x-axis of the curve y = cos x.

Step-by-step explanation:

As we know, the value of cosx lies between (-1,1) and its graph is a curve. Its value keeps on varying between -1 and 1 only depending on the value of x.

The value of y is \text{0} at x = \frac{\pi}{2}. Few values are labeled in the figure attached in the answer. The value y is 1 at x = 0.

The curve shown in blue color solid line represents the curve of y = cos x.

And the curve shown in the dotted green color in the attached figure represents the reflection in the x-axis.

The volume of a? cone-shaped hole is 49 pi ft cubed . If the hole is 3 ft? deep, what is the radius of the? hole?
lidiya [134]

\bf \textit{volume of a cone}\\\\ V=\cfrac{\pi r^2 h}{3}~~ \begin{cases} r=radius\\ h=height\\[-0.5em] \hrulefill\\ h=3\\ V=49\pi \end{cases}\implies 49\pi =\cfrac{\pi r^2(3)}{3}\implies 49\pi =\pi r^2 \\\\\\ \cfrac{49\pi }{\pi }=r^2\implies 49=r^2\implies \sqrt{49}=r\implies 7=r

I am looking to decrease my bill by 25%. Can you look at my current plan and tell me what I can remove to achieve this reduction
Gennadij [26K]

Answer: $35

Step-by-step explanation:

From the question, we are informed that the current bill of the person is $140.00 per month and that the person wants to decrease the bill by 25%.

To know the amount that the person needs to deduct, we have to calculate 25% of $140.00. This will be:

= 25% of $140

= 25/100 × $140

= 1/4 × $140

= 0.25 × $140

= $35

The person will need to remove $35. The person will now pay ($140 - $35) = $105 monthly.
