The radius of the circle on a basketball court is 6 feet. What are the approximate circumference and area of the circle?

AlexFokin [52]

Circumference formula - 2pi(r)
area formula - pi(r)^2
in both of the formulas r is the radius so

to find circumstance: 2(pi)(6) = 25.68 feet

to find area: pi(6)^2 = 113.04 feet

PLEASE HELP!!!!!!!!

vfiekz [6]

Answer:

about 78 years

Step-by-step explanation:

Population

y =ab^t where a is the initial population and b is 1+the percent of increase

t is in years

y = 2000000(1+.04)^t

y = 2000000(1.04)^t

Food

y = a+bt where a is the initial population and b is constant increase

t is in years

b = .5 million = 500000

y = 4000000 +500000t

We need to set these equal and solve for t to determine when food shortage will occur

2000000(1.04)^t= 4000000 +500000t

Using graphing technology, (see attached graph The y axis is in millions of years), where these two lines intersect is the year where food shortages start.

t≈78 years

Can someone please help me with these questions!!!!

IgorLugansk [536]

Answer: B

Step-by-step explanation:

The only labeled angle is 111

We can conclude that angle 3 is also 111

1 and 2 are both less than 90

Therefore, 1 is 69, 2 is 69, and 3 is 111

Determine the discriminant for the quadratic equation -3 = x^2+4x+1 . Based on the discriminant value, how many real number solu

djverab [1.8K]

Answer:

1 real

Step-by-step explanation:

The discriminant is:

$b^2-4ac$

which comes from the quadratic formula.

The rules are:

If the discriminant is > 0, there are 2 real solutions

If the discriminant is = 0, there is 1 real solution

If the discriminant is < 0, there are 2 imaginary solutions

(there are 2 other situations involving square roots, but these are the most basic ones in Algebra 2 books when you study quadratics)

First, we have to get that quadratic in standard form, which means getting everything on one side of the equals sign and setting it equal to 0:

$x^2+4x+4 = 0$

where a = 1, b = 4, c = 4

Filling in the discriminant:

$4^2-4(1)(4)$

gives us

16 - 16 = 0

Therefore, our quadratic has one real solution. Factor it and see if you'd like, to prove that it is true.

Ugo [173]

Answer: 1 13/20 miles

Explanation:

$5 - 2\cfrac{1}{10} - 1 \cfrac{1}{4} = 5 \cfrac{0}{20} - 2\cfrac{2}{20} - 1 \cfrac{5}{20} = 4 \cfrac{20}{20} - 2\cfrac{2}{20} - 1 \cfrac{5}{20} = 1 \cfrac{13}{20}$
