Melissa was recording the heights of 4 flowers in her garden. The rose bush grew 12 inches in 1 month, the daisies grew 5 inches in 2 weeks, the tulips grew 8 inches in 3 weeks, and the daffodils grew 3 inches in 1 week. Which flower grew at the slowest rate?

Daisies flower grows the slowest

Step-by-step explanation:

We are given;

Rate of growth of rose bush; 12 inches in 1 month.

1 month = 4 weeks.

Thus, we have; 12 inches in 4 weeks.

In 1 week, it grows; 12/4 = 3 inches per week

Rate of growth of daisies; 5 inches in 2 weeks. Thus, in 1 week, it grows by; 5/2 = 2.5 inches per week.

Rate of growth of tulips; 8 inches in 3 weeks. In one week, it grows by; 8/3 = 2.67 inches per week

Rate of growth of daffodils; 3 inches in 1 week = 3 inches per week

Looking at all the rates above, the slowest is 2.5 inches per week. This is for daisies.

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.
