A weight is attached to the end of a spring. Its height after t tt seconds is given by the equation h ( t ) = 5 − 2 sin ⁡ ( 2 π ( t + 1 ) 7 ) h(t)=5−2sin( 7 2π(t+1) )h, left parenthesis, t, right parenthesis, equals, 5, minus, 2, sine, left parenthesis, start fraction, 2, pi, left parenthesis, t, plus, 1, right parenthesis, divided by, 7, end fraction, right parenthesis. When does the weight first reach its maximum height? Give an exact answer.

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!

answer: 0,6

step-by-step explanation:

this would make it the y intercept.

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
