Ms. Jarrett wanted to know how many parents were going to attend the parent night last September. So, two weeks before parent night, she sent every parents a card asking, "Do you plan to attend parent night in two weeks? please circle one Yes or No." Then she waited for the cards to be mailed back to the school.

Question 1 options:

Experiment

Survey

None of these

Observational Study

- both graphs increase on their domain.

- the graphs of both functions have the same x-intercept.

- neither graph has a y-intercept.

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this

the circumference of a circle is, 10.676 cm.

step-by-step explanation:

the formula for circumference of a circle is given by:

where

c is the circumference of a circle and

d is the diameter of a circle.

given: diameter(d) = 3.4 cm and use

substitute these values in [1] we get;

cm

therefore, the circumference of a circle is, 10.676 cm
