The equation below describes a parabola. If a is positive, which way does the parabola open? x = ay2

Angelina_Jolie [31]

One of the best way to solve these kinds of questions is to draw 3-4 points and than conclude from that how graph will go.

Because this function is f(y) (x depends on y) you randomly take several y values and calculate x for them and those are your pairs of coordinates of several points.

y = 0
x = 0

y = 1
x = a

y = -1
x = a

y = 2
x = 4a

y = -2
x = 4a

So if you draw these points on graph you will see it opens in positive direction of x axis.

A 2 pound bag of wildflower send covers 4 square feet how many of seed it takes to cover 1 square foot

Harlamova29_29 [7]

Answer:

Step-by-step explanation:

2 lb bag to 4 sq ft = 1 lb bag to x sq ft

2 / 4 = 1 / x

cross multiply because this is a proportion

(2)(x) = (1)(4)

2x = 4

x = 4/2

x = 2 <==== so a 1 lb bag covers 2 sq ft

What is the GCF of the terms 14c²d and 42c³d? A. 2c²d B. 7c²d C. 3c D. 14c²d

GuDViN [60]

GCF - What is the highest number possible that the two given terms have in common.

In the given problem, one can clearly see that the two share $c^{2} and d$ .

The factors of 14 are 1, 2, 7 and 14 while the factors of 42 are 1, 2, 3, 6, 7, 14, 21 and 42.
Out of the two, 14 is the highest number that they both share.

So our answer will be 14 $c^{2} d$
