What are the sine cosine and tangent of theta=7pi/4 radians

answer:

the dryer cost 325

step-by-step explanation:

let w = the cost of the washer

d = cost of the dryer

w+d = 701

w = d+51

replace w in the first equation with d+51

d+51 +d = 701

combine like terms

2d+51 = 701

subtract 51 from each side

2d+51-51 = 701 -51

2d = 650

divide by 2

2d/2 = 650/2

d = 325

the dryer cost 325

answer:

x = 4/7

step-by-step explanation:

5/3 x = 20/21

multiply by 3/5 on each side to isolate x

3/5 *5/3 x = 20/21 * 3/5

x = 20/21 * 3/5

rewriting the right hand side

x = 20/5 * 3/21

x =4 * 1/7

x = 4/7

answer: the standard form of equation will be

step-by-step explanation:

since we have given that

the vertex form of equation is given by

we need to find the standard form :

standard form is written as :

so, our equation becomes,

hence, the standard form of equation will be
