<h3>Explanation</h3>

Linear

Linear is a straight line. You might have heard of Linear Function.

$y = mx + b$

The equation above is slope-intercept form.

Exponential

Exponential is both increasing graph and decreasing graph depending on the coefficient.

Exponential Equation

$y = {a}^{x} \: \: \: (a > 0) \: \: (a \neq1)$

Exponential Graph increases when a-term is greater or equal to 1.

Exponential Graph decreases when a-term is greater than 0 but less than 1.

From the equation, it is exponential of x-term as an exponent. The equation matches with exponential form.

<h3>Answer</h3>

Exponential

Find II 2e-3f II^2 assuming that e & f are unit vectors such that II e +f II=sqrt(3/2).

sergey [27]

We are given that ||e|| = 1, ||f|| = 1. 

Since ||e + f|| = sqrt(3/2), we have 
3/2 = (e + f) dot (e + f) 
= (e dot e) + 2(e dot f) + (f dot f) 
= ||e||^2 + 2(e dot f) + ||f||^2 
= 1^2 + 2(e dot f) + 1^2 
= 2 + 2(e dot f). 

So e dot f = -1/4. 

Therefore, 
||2e - 3f||^2 = (2e - 3f) dot (2e - 3f) 
= 4(e dot e) - 12(e dot f) + 9(f dot f) 
= 4||e||^2 - 12(e dot f) + 9||f||^2 
= 4(1)^2 - 12(-1/4) + 9(1)^2 
= 4 + 3 + 9 
= 16.

Find the surface area of the rectangular box below

REY [17]

Answer:

SA = 904 in.²

Step-by-step explanation:

Surface Area (SA) of a cuboid: 2(lw) + 2(wh) + 2(hl)

SA = 2(lw) + 2(wh) + 2(hl)

l = 36 in.
w = 10 in.
h = 2 in.

Substitute the given values and multiply:

SA = 2(lw) + 2(wh) + 2(hl)

SA = 2(36)(10) + 2(10)(2) + 2(2)(36)

SA = 2(360) + 2(20) + 2(72)

SA = 720 + 40 + 144

SA = 904 in.²

Hope this helps!

Which table represents a linear function? (will give brainliest)

kvasek [131]

Answer:

$\huge\mathfrak\pink{S} \huge\mathfrak\purple{o} \huge\mathfrak\blue{l} \huge\mathfrak\red{u} \huge\mathfrak\green{t} \huge\mathfrak\pink{i}\huge\mathfrak\purple{o}\huge\mathfrak\red{n}\huge\mathfrak\orange{:}\$

Linear function :The characteristic property of linear functions is that when the input variable is changed, the change in the output is proportional to the change in the input. Linear functions are related to linear equations.

Step-by-step explanation:

We have

y=mx+c
