Answer:

if pi is 3.14: 163.52 m^2

if pi is just π: 264 - 32π m^2

Step-by-step explanation:

22 x 12 = 264

4 x 4 = 16

16 x 2 = 32

16 x 3.14 = 50.24

264 - 50.24 x 2 = 163.52

Answer:

163.47

Step-by-step explanation:

We know the area of the whole rectangle by multiplying 12 by 22 to get 264. Now we just have to find the area of the circles and subtract it from the rectangle.

The area of a circle is πr^2. These circles' radii is 4, so 4^2π = 16π

Since there are 2 circles, double 16π to get 32π, 32π is equal to 100.53096491, rounded to 100.531. 264 - 100.531 = 163.469, rounded to 163.47

For what values of m does the graph of y = 3x^2+ 7x + m have two x-intercepts?
qaws [65]

Answer:

m < 49/12

Step-by-step explanation:

The portion of the quadratic formula under the square root sign is the discriminant.

If the discriminant is > 0 then there are two real roots.

b² -4ac > 0

-----------------------------

7² - 4(3)m > 0

49 - 12m > 0

Subtract 49 from both sides

-12m > -49

Divide both sides by -12

(when multiplying or dividing by a negative the inequality must be reversed)

m < 49/12

ankoles [38]

Answer:

Option C.

Step-by-step explanation:

Sampling bias is a problem during the initial data gathering step of a survey.

The problem occurs when the design of the study is wrong the data collection procedure is wrong.

So, here answer seems C, because the starting point is not selected at random in this survey.
