Answer:
ok so first lets find the answer to the original question
28+7=35
so lets find which one is equal to 35
7(4+1)=28+7=35 yes
4(7+1)=28+4=32 no
4(7+3)=28+12=40 no
7(4+7)=28+49=77 no
a is the answer
Hope This Helps!!!
Answer:
r = 55.2 cm
Step-by-step explanation:
the arc length is calculated as
arc = circumference × fraction of circle
= 2πr × 
( r is the radius )
given arc = 63.48π , then
2πr × = 63.48π ( cancel 2π on numerator/ denominator )
r × 
π = 63.48π ( divide both sides by π )
= 63.48 ( multiply both sides by 20 to clear the fraction )
23r = 1269.6 ( divide both sides by 23 )
r = 55.2 cm
To vertically strech or shrink a function, multily the whole function by the factor taht you want to strech or shrink it by
to horizontally strech or shrink a function, multiply every x by the factor you want to strech or shrink it by
shrinks mean multiplying by a value greater than -1 and less than 1
stetch means multiply by a value greater than 1 or less than -1
first one
horizontal shrink
muliply every x by a fraction
so that is A
2nd one
vertical strech
multiply whole function by a value greater than 1 or less than -1
D is the answer
3rd one
horizontal strech
multiply every x by a value greater than 1 or less than -1
C is the answer
4th one
vertical shrink
multiply whole function by a value greater than -1 and less than 1
B is the answer
