4 0

Step-by-step explanation:

40 increases to 56.

<u>To find the percent increase:</u>

Subtract the increased value from the original value.

Divide the difference by the original value.

Multiply the quotient by 100 to represent the percent.

<u>Solve:</u>

56 - 40 = 16

16 \div 40 = 0.4

0.4 \times 100 = 40

There's a 40% increase.

Let x = the circumference of the circle

then

(24-x) = the perimeter of the square

:

Find the area of the circle

find r

2*pi*r = x

r =  

Find the area of the circle

A =  

A =  

A =  sq/cm, the area of the circle

:

Find the area of the square

A =  sq/cm the area of the square

The total area

At =  +  

Graph this equation, find the min

Min occurs when x=10.6 cm

cut string 10.6 cm from one end

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
