1 answer:
Answer: 2.5722 .
_____________________________________________________
Explanation:
_________________________________________________
log(base "
" of 19 = y ? ; Solve for "y" ;
__________________________________________________
^ (y) = 19 ; Solve for "y" ?
__________________________________________________
Take the "ln" (that is, "natural logarithm", of both sides:
__________________________________________________
ln [ ^ (y) ] = ln 19 ;
__________________________________________________
y * ln = ln 19 .
__________________________________________________
Use "3.1416" as an approximation for: " " ;
__________________________________________________
y * ln (3.1416) = ln 19 ;
__________________________________________________
Divide EACH side of the equation by: " [ ln (3.1416) ]" ; to isolate "y" on one side of the equation; and to solve for "y"; (Use a calculator to do this) ;
_________________________________________________________
y * ln (3.1416) / [ ln (3.1416) ] = ln 19 / [ ln (3.1416) ] ;
________________________________________________________
y = ln 19 / [ ln (3.1416) ] ;
_______________________________________________________
y = 2.5721639670047041 ;
→ round to nearest 4 (FOUR) decimal places;
_______________________________________________________
→ y = 2.5722 .

1) First find the coordinates of the shape:
G(-1, -2), F(-1, -1), E(2,2), D(2, -2)
2)It asked for dilation of 2 about the origin.
<u><em>*What is dilation?</em></u>
<em>Dilation is the expanding/enlarging a transformation by a scale factor</em>
Now we multiply all the coordinates with the factor of 2
G(-1*2, -2*2) = G'(-2, -4)
F(-1*2, -1*2) = F'(-2, -2)
E(2*2, 2*2) = E'(4, 4)
D(2*2, -2*2) = D'(4, -4)
3) Now plot these points and graph the transformation:
