Mathematics
1 answer:
Nitella [24]3 years ago
6 0

Step-by-step explanation:

Sum of measures of all internal angles of a hexagon is 720°

\therefore \: x + 120 \degree +  142 \degree +  137 \degree  \\  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: +  151 \degree +  106\degree  =  720 \degree  \\  \\  \therefore \: x +6 56 \degree=  720 \degree  \\  \\  \therefore \: x =  720 \degree  - 656 \degree\\  \\  \therefore \: x =  720 \degree  - 656 \degree \\  \\   \therefore \: x = 64 \degree

The function f(x) = x2 is translated 7 units to the left and 3 units down to form the function g(x). Which represents g(x)? g(x)
Verdich [7]

Answer:

g(x)=(x+7)^2-3

Step-by-step explanation:

Given:

f(x)= x^2

Now we have to translate f(x) 7 units to the left and 3 units down to form the function g(x).

As per the rules of translation

when any parent function, in given case f(x)=x^2, is translated to 'a' units to the left then 'a' is added to the value of x. thus making f(x+a)

Also when the parent function is translated any 'a' units down then 'a' is subtracted from the value of function. thus making f(x)-a

Translating f(x), 7 units to the left

f(x+7)= (x+7)^2

Translating f(x+7), 3 units down

f(x+7)-3 = (x+7)^2-3

Hence new function g(x)=(x+7)^2-3!
