Answer:

divide the interest amount by the product of the principal and time

Step-by-step explanation:

The simple interest formula is I = prt where I is the interest, p is the principal, r is the rate and t is the time (in years). Rewriting this formula so that r is the subject we get r = I / pt. Therefore the answer is divide the interest amount by the product of the principal and time.

Find the minimum or maximum of the function. Describe the domain/range in interval notation y=6x^2-1
Margarita [4]

max is at vertex

in form y=ax^2+bx+c

the x value of the vertex is \frac{-b}{2a}

given, y=6x^2-1

a=6, b=0

the x value of the vertex is -0/(2*6)=0

the y value is y=6(0)^2-1=0-1=-1

so vertex is at (0,-1)

since the value of a is positive, the parabola opens up and the vertex is a minimum value of the function

therefore that value is the smallest value the function can be



domain=numbesr you can use for x

range=numbesr you get out of inputting the domain


domain=all real numbers

range is {y | y≥-1} since y=-1 is the minimum

A vitamin C tablet contains 1/40 of a gram of vitamin C. You take 1&1/2 tablets Evry day. How many grams of vitamin C do u t
Alexxandr [17]

Answer:

Either 3/80 grams or 0.0385 grams

Step-by-step explanation:

1 tablet = 1/40 of a gram

1/40 of a gram = 1 ÷ 40 = 0.025 grams

1 tablet = 0.025 grams

1.5 tablets = x

1/1.5 = 0.025 / x                  Cross multiply

x*1 = 0.025 * 1.5                  Combine the factors

x = 0.0375 grams                Convert to a fraction

0.0375 = 3/80
