Answer:

B. 41

Step-by-step explanation:

Missing sides of a right triangle can be found using the Pythagorean Theorem.  The formula for the Pythagorean Theorem is: a² + b² = c², where 'a' and 'b' represent the legs of the triangle and 'c' represents the hypotenuse.  Since the leg lengths of the right triangle are given as 9cm and 40cm, we can set up the following equation:

9² + 40² = c²  or 81 + 1600 = c²

1681 = c²

Take the square root of both sides: √1681 = √c²

c = 41 (answer choice B)

Evaluate the function f(x)=x^2-5x+ 5 at the given values of the independent variable and simplify
11111nata11111 [884]

Step-by-step explanation:

The given function is :

f(x)=x^2-5x+ 5

(a) To find f(9), put x = 9 in the above expression.

f(9)=9^2-5(9)+ 5=41

(b) To find f(x+7), put x = x+7 in the above expression.

f(x+7)=(x+7)^2-5(x+7)+ 5\\\\=x^2+14x+49-5x-35+5\\\\=x^2+9x+19

(c) To find f(-x), put x = -x in the above expression.

f(-x)=(-x)^2-5(-x)+ 5\\\\=x^2+5x+5

Hence, this is the required solution.

Answer this please it’s for algebra 2
Sergeu [11.5K]

Part a)

P(junior) = (number of juniors)/(number total)

P(junior) = 235/705

P(junior) = 1/3 exactly

P(junior) = 0.33333 approximately

======================================

Part b)

P(freshman and LG) = (number of freshman who have LG)/(number total)

P(freshman and LG) = 70/705

P(freshman and LG) = 14/141 exactly

P(freshman and LG) = 0.09929 approximately

======================================

Part c)

n(junior) = number of juniors = 235

n(samsung) = number of people who have samsung = 274

n(junior and samsung) = number of juniors who have samsung = 93

----

n(junior or samsung) = n(junior)+n(samsung)-n(junior and samsung)

n(junior or samsung) = 235+274-93

n(junior or samsung) = 416

----

P(junior or samsung) = n(junior or samsung)/n(total)

P(junior or samsung) = 416/705 exactly

P(junior or samsung) = 0.59007 approximately

======================================

Part d)

n(sophomore and apple) = number of sophomores who have apple

n(sophomore and apple) = 80

n(apple) = number of students who have apple

n(apple) = 261

P(sophomore | apple) = n(sophomore and apple)/n(apple)

P(sophomore | apple) = 80/261 exactly

P(sophomore | apple) = 0.30651 approximately

======================================

Part e)

define the events

A = junior who has apple

B = junior who has samsung

C = person is a junior

n(A or B) = number of juniors who have apple or samsung

n(A or B) = n(A) + n(B) ... A and B assumed mutually exclusive

n(A or B) = 87+93

n(A or B) = 180

n(C) = 235

P( (Apple or Samsung) | Junior ) = n(A or B)/n(C)

P( (Apple or Samsung) | Junior ) = 180/235

P( (Apple or Samsung) | Junior ) = 36/47 exactly

P( (Apple or Samsung) | Junior ) = 0.76596 approximately
