pi over 4

@SolomonZelman Lplz plz plz help me asap

Answer 1

I NEED HELP PLZZ

Answer 2

got a picture?

Answer 3

The highest point goes from (0, 5) down to (pi/2,2) back down to (pi,-1) up to (3pi/2,2) and back up to( 2pi,5)

Answer 4

rate of change would be \[\frac{2+1}{\frac{3\pi}{2}-\pi}\] which is none of your choices

Answer 5

oh maybe it is

Answer 6

\[\frac{3}{\frac{\pi}{2}}=\frac{6}{\pi}\] is that an option?

Answer 7

yeah it is
go with B

Answer 8

thankss!!

Answer 9

yw

Answer 10

Simplify cos2 Θ(1 + tan2 Θ).

cos2 Θ + sin2 Θ
cos2 Θ
1
−1
@satellite73

Answer 11

\[\cos^2(\theta)(1+\tan^2(\theta))\]

Answer 12

thank you sooo much!

Answer 13

Simplify (1 − sin x)(1 + sin x).

1
cos2 x
sin2 x
tan2 x

Answer 14

use the identity
\[1+\tan^2(\theta))=\sec^2(\theta)\]

Answer 15

hold on got the question marks fo death again

Answer 16

ok

Answer 17

B?

Answer 18

if you multiply you get
\[1-\sin^2(\theta)\] as a first step yeah B

Answer 19

Compare the functions shown below:


f(x) = 3 cos 2x + 4
g(x)

cosine graph with points at 0, 3 and pi over 2, 0 and pi, negative 3 and 3 pi over 2, 0 and 2 pi, 3
h(x)

x y
-6 -11
-5 -6
-4 -3
-3 -2
-2 -3
-1 -6
0 -11


Which function has the greatest maximum y-value?
f(x)
g(x)
h(x)
All three functions have the same maximum y-value.

Answer 20

@satellite73

Answer 21

maximum we want right?

Answer 22

yes

Answer 23

hard for me to tell without the picture, but the maximum of cosine is 1, so the maximum of \(3\cos(2x)+4\) is \(3+4=7\)1

Answer 24

look at the graph of \(g\) and find the top most point
let me know if it is more or less than 7

Answer 25

its 3 less

Answer 26

ok then pick that on \(f\) because the max of \(h\) looks like \(-2\)

Answer 27

so A?

Answer 28

yeah

Answer 29

Compare the functions shown below:


f(x) = 4x + 5
g(x)

tangent function with y intercept at 0, 2 h(x) = 3 sin(2x + π) - 2


Which function has the greatest y-intercept?
f(x)
g(x)
h(x)
All three functions have the same y-intercept.

Answer 30

Compare the functions shown below:


f(x)

polynomial graph with x intercepts at negative 3, negative 2, 1, 2, y intercept at negative 12
g(x)

trig graph with points at 0, 3 and pi over 2, 0 and pi, negative 3 and 3 pi over 2, 0 and 2 pi, 3
Over the interval x = 0 to x = 2π h(x) = 2x3 − 2x2 − 3x + 2


Which function has the most x-intercepts?
f(x)
g(x)
h(x)
All three functions have the same number of x-intercepts.

Answer 31

Compare the functions shown below:


f(x)

x y
-3 -27
-2 -8
-1 -1
0 0
1 1
2 8
3 27
4 64
g(x)

linear graph with y intercept of negative 1 and x intercept of negative 2 h(x) = (x + 4)2 + 2


What is the correct order of the functions from least to greatest according to the average rate of change on the interval from x = 0 to x = 4?
f(x), g(x), h(x)
g(x), f(x), h(x)
h(x), g(x), f(x)
g(x), h(x), f(x)

Answer 32

Compare the functions shown below:


f(x) = 2 sin (3x + π) − 2 g(x) = (x − 3)2 − 1
h(x)

x y
-2 3
-1 -2
0 -5
1 -6
2 -5
3 -2
4 3


Which function has the smallest minimum y-value?
f(x)
g(x)
h(x)
Both g(x) and h(x) have the same minimum y-value.

Answer 33

this is not working for me, too many question marks

Answer 34

refresh the page and you'll be able to see them without any question marks

Answer 35

@ganeshie8 can u plz help me?

Answer 36

looks like you're given 3 functions and asked to find which function has minimum y-value

Answer 37

no on a nother question

Answer 38

Okay can you post it as new question.. ? :)

Answer 39

alright :)
