The answer is the 3 trapsizoid as it’s interior is invert
The answer is y/x=1
The image shown is a Unit circle
And if theta is pi/4 than the (x,y) coordinates of that point will both be sqrt2/2
If you divide a number by itself it equals 1
Answer:
10 dimes and 14 quarters
Step-by-step explanation:
take the amount of four quarters to start with: 1$
then from here, for add one quarter and one dimes worth: 35 c
keep adding until you reach 450
then count how many 35 c you counted and thats how many dimes you have
add four to that number and youll get the amount of quarters
8x^2+6x^2+4x=138 combine like terms on left side
14x^2+4x=138 since the number of seats in the from row is just 4x, subtract 14x^2 from both sides
4x=138-14x^2 that would be the general solution, if you wanted the actual number you would have to solve for x and then multiply that value by 4 to know what "4x" is...
14x^2+4x-138=0
14x^2-42x+46x-138=0
14x(x-3)+46(x-3)=0
(14x+46)(x-3)=0
2(7x+23)(x-3)=0, since x>0
x=3 and thus
4x=12 seats
So there are 12 seats in the front row addition.
Question 4 is d question 3 is c
