Answer:
7(7x -4)
Step-by-step explanation:
49x-28
We can factor a 7 from each term
49x = 7*7x
28 = 7*4
7(7x -4)
Answer: since the parent function is f(x), then i think....
f(x) + 5 is the shifted 5 units up of f(x)
then the first answer is correct
f(x - 8) is 8 shifted 8 units right of f(x)
then the second answer is wrong,
f(x) is replaced by 4f(x) means it stretched vertically by a factor of 4
the the third answer is correct
f(x) is replaced with f(3x) compressed horizontally by a scale factor of 1/3
then the fourth answer is correct
Step-by-step explanation: i hope this makes since and sorry if it doesn't so the first is correct, second is wrong, third is correct, and fourth is also correct. and no there well be no links. (sorry if you do want links)
and maybe a brainliest
Answer:
80.4
Step-by-step explanation:
21.03 + 80.4 - 21.03
21.03 - 21.03 cancel each other out because it equals 0.
The equation becomes 0 + 80.4 = 80.4
Answer:
1/sqrt10
Step-by-step explanation:
1) Find out cosA using formula (cosA)^2+(sinA)^2=1
The module of cosA= sqrt (1- (-3/5)^2)= sqrt 16/25=4/5
So cosA=-4/5 or cosA=4/5.
Due to the condition 270degrees< A<360 degrees, 0<cosA<1 that's why cosA=4/5.
2) Find sinA/2 using a formula cosA= 1-2sinA/2*sinA/2 where cosA=4/5.
(sinA/2)^2= 0.1
sinA= sqrt 0.1= 1/ sqrt10 or sinA= - sqrt 0.1= -1/sqrt10
But 270°< A< 360°, then 270/2°<A/2<360/2°
135°<A/2<180°, so sinA/2 must be positive and the only correct answer is
sin A/2= 1/sqrt10
