<span>"  B is your best choice but it is very badly stated. this gives an Example of the Pythagorean theorem. it does Not demonstrate it. B is written incorrectly, it should say "sum of squares of the lengths of the legs" Not "sum of the lengths of the two legs of any right angle squared"</span>

Which is a irrational number, √39, √9, √49, 1.7
stiv31 [10]

Answer:

√39

Step-by-step explanation:

An irrational number is a number that cannot be expressed by a fraction.

√9 = 3

√49 = 7

All whole numbers can be expressed as fractions and are <u>not</u> irrational numbers.

1.7 = 17/10 which is <u>not</u> an irrational number.

Jackson purchases a new car for $48,000. The car's value can be modeled by the
vekshin1

We have been given that Jackson purchases a new car for $48,000. The car's value can be modeled by the  following exponential function: y = 48000(0.76)^t where y represents the car's  value and t represents time in years. We are asked to find the decay rate as a percentage.

We know that an exponential decay function is in form y=a\cdot (1-r)^x, where,

y = Final value,

a = Initial value,

r = Decay rate in decimal form,

x = time.

Upon comparing our given function y = 48000(0.76)^t with standard decay function  y=a\cdot (1-r)^x, we can see that 1-r=0.76.

Let us solve for r.

1-1-r=0.76-1

-r=-0.24

r=0.24

Let us convert 0.24 into percentage.

0.24\times 100\%=24\%

Therefore, the decay rate is 24%.

Helpppppp plsss!!!!!!graph it on your paper​ will give brainliest
nydimaria [60]

Answer:

see attached

Step-by-step explanation:

graph y = -3/2x - 2

x Intercept:  0 = -3/2x -2

               3/2x = -2

                    x = <u>-2 (2)</u>

                            3

                    x = -4/3

                   (-4/3,  0)

y intercept: (0, -2)
