I need help finding the reference angles for these angles.
Salsk061 [2.6K]
Convert the angles to degrees. Remember there are 2pi radians in a circle, and a circle has 360 degrees, so conversion factor is 180degrees/pi. Then you can easily approximate the reference angle. Remember you make the reference angle from the positive x-axis and the reference angle will be the angle between the terminal side and the nearest x-axis (either positive side or negative side of the x-axis).
1)1.4 * \frac{180degrees}{pi} = 80.214 degrees
2)-1.4 \pi * \frac{180degrees}{ \pi } = -252 degrees

HELP PLEASE <br> Write the inequality that models the number granola bars (12) you need to buy.
Goshia [24]
The correct question in the attached figure

Let
x-------------> <span>the number of granola bars 
y-------------> the pounds of fruit

we know that

if 12 bars------------> cost $12
 1 bars--------------> X
X=12/12---> x=$1
1 bar---------> cost $1

if 9 pounds of fruit----------> cost $36
 1 pound-------------------> X
X=36/9--------> x=$4
1 pound -------> cost $4

</span><span>expression for the total cost=(1)*x+(4)*y----------> x+4y
</span><span>x=12
y=9
then
</span>the total cost=12+4*9----- $48

<span>an inequality that compares
the total cost with the amount you have to spend is
x+4y<=48
</span>
using a graph tool see the attached figure

<span>the inequality that models the number of granola bars you need to buy is
</span>
x<=12  the solution for the number of granola bars is the interval [0,12]

The product of p and 6
inna [77]

Answer:

plz tell the full question well i hope this will help.

Step-by-step explanation:

The key word to note is 'product'. A product is the answer to a multiplication operation.

The product of 3 and 4 means 3×4=12

12 is the product.

In this question we are working with algebra, but it means the same.

The product of pandq means p×q=pq

The product is pq. This is an algebraic term which cannot be simplified further and cannot be evaluated unless you know the values for pandq
