The equation line passing through a point is understood to be parallel to the x-axis. In this case, the equation should be expressed as y = b where b is any number. Since y = 14 in the point (1,14), the equation of horizontal line passing through this point is y = 14.

If a party hat has a radius of 3 inches, what is the area of the circular base?

Slav-nsk [51]

Answer:

$A=9\pi\ in^2$

Step-by-step explanation:

<u>Area of a Circle</u>

A circle is a geometric shape where all the points on its circumference are at the same distance to a fixed point called center. The radius is the distance from the center to any point of the circumference.

The relation of the length of the circumference to the radius is an irrational number called pi ( $\pi\approx 3.141592$ ).

Another interesting relation in a circle is the area it occupies in a 2D space. Being r the radius of the circle, the area is computed by the formula

$A=\pi r^2$

The party hat has a radius of r= 3 inches. The area of the circular base is computed as follows

$A=\pi\cdot 3^2$

$\boxed{A=9\pi\ in^2}$

For the first four days of a five day vacation, the mean temperature was 80 degrees. What must the temperature be on the fifth d

V125BC [204]

Answer:

The 5th day must be 90

Step-by-step explanation:

The first 4 days averaged out to 80

You can find their total just by multiplying by 4. That won't tell you the exact values, but it will tell you their total when you add the 4 of them together.

80*4 = 320

Now you need to add another day into the mix. Call it x

320 + x

Now there are 5 days, not 4, and the new total is 82.

(320 + x) / 5 = 82 Multiply both sides by 5

5*(320 + x) / 5 = 82 *5

320 + x = 410 Subtract 320

-320 -320

x = 90

The number of compact discs N purchased each year, in millions, can be

Aleonysh [2.5K]

Answer:

126.5 years

Step-by-step explanation:

N(t) = 384(1.13)^t

2,000,000,000 = 384(1.13)^t

(1.13)^t = 2,000,000,000/384

log [(1.13)^t) = log (2,000,000,000/384)

t × log 1.13 = log (2,000,000,000/384)

t = [log (2,000,000,000/384)]/(log 1.13)

t = 126.5

Answer:

6802

Step-by-step explanation:

Number of liberaries = 8950

76% offered free acces to ebooks.

How many offered access to ebook = 76% / 100% x 8950

= 0.76 x 8950

= 6802
