Solving a-\frac{4}{5}=12 we get a=\frac{64}{5}

Step-by-step explanation:

We need to find the value of a. We are given:

a-\frac{4}{5}=12

Solving:

a-\frac{4}{5}=12\\Add\,\,\frac{4}{5}\,\,on\,\,both\,\,sides:\\a-\frac{4}{5}+\frac{4}{5}=12+\frac{4}{5}\\a=12+\frac{4}{5}\\Taking\,\,LCM:\\a=\frac{12*5+4}{5}\\a=\frac{60+4}{5}\\a=\frac{64}{5}

So, Solving a-\frac{4}{5}=12 we get a=\frac{64}{5}

Answer:

1) 102.7 meters

2) 11

Step-by-step explanation:

1) -4.9x² + 75x = -4.9x² + 50x + 38

25x = 38

x = 1.52 s

Height = -4.9(1.52)² + 75(1.52) = 102.67904 m = 102.7 m

2) f(x) = x² + 3x - 2

f(2) = 2² + 3(2) - 2 = 8

f(6) = 6² + 3(6) - 2 = 52

Average rate of change:

(52-8)/(6-2) = 11

PLZ HELP!! Which real numbers are zeroes of the function?
astra-53 [7]

The correct answers are: 1/2, 2 and -2.


To get this, factor f(x)

f(x)=2x^3-x^2-8x+4

f(x)= (2x^3-x^2) - (8x -4)

f(x)= (2x-1)(x^2) + (2x-1)(-4)

f(x)= (2x-1)(x^2-4)

f(x)= (2x-1)(x-2)(x+2)


2x-1=0

2x=1

x=1/2


x-2=0

x=2


x+2=0

x=-2
