Inga [223]3 years ago

Answer:

2.3

Step-by-step explanation:

Using SOH CAH TOA, we can label CB as the alternate side seeing as it's opposite to the known angle 50 degrees. We know AB is the hypotenuse since it's the longest side. Therefore CA must be the alternate side.

Since we want to know BC, and we know information about AB, we need to use the use of the hypotenuse and the opposite. In SOH CAH TOA, SOH uses both of these.

Using S O H, we understand that sin(50) * 3 = CB

Therefore CB = 2.3 to 1 decimal place.

Fabio is designing a flashlight that uses a parabolic reflecting mirror and a light source. The shape of the mirror can be model
ohaa [14]

Answer:

(2, 11/2)

Step-by-step explanation:

This is a vertical parabola; we know that because x is squared here, while y is not.  The standard equation of a vertical parabola with vertex (h,k) is

4p(y-k) = (x-h)^2, where p is the distance between the vertex and the focus.  Comparing

4p(y-k) = (x-h)^2 to

10(y-3)  = (x-2)^2, we see that 4p = 10.  Therefore, p = 10/4 = 5/2, which is the vertical distance between the focus and the vertex.

Since the coordinates of the vertex are easily read from the given equation

(x-2)^2=10(y-3):  (h,k) = (2, 3)

all we need to do is to add p (5/2) to the y-coordinate (3);

The focus is at (2, 3 + 5/2), or (2, 11/2).

You sell candy at a football game for $1.50 each. You paid $50 for 300 candy bars. what is the domain and range for your profit?
-Dominant- [34]

Answer:

Domain is number of candy or 300

Range is profit from selling candy or $50

Step-by-step explanation:

Domain is the numbers you are allowed to use in your function. In this case, it would be the amount of candy you sold.

The range is the output from inputting the number(s) in the domain. In this case, the range is the amount of money you profit.

Profit=(amount gained)-(amount lost)

amount gained is from selling candy

amount lost is what you invested to get the candy

amount gained=(cost per candy)X(number of candy)

amount gained=(1.50)(300)

amount gained=$450

amount lost=$50

therefore

Profit=450-40=$400

a function for profit can be as follows:

P(x)=1.5x-c

where amount you sold each candy for, c is cost for those x candies, and P(x) is the profit for x candies
