Which expression is equivalent to 5.4+3.4w-1.8w +5.8 A) 7(1.6+w) B) 1.6(7+w) C) 1.6(7w) D) 1.6(0.25+w)

Do 5.4 plus 5.8 then do 3.4w minus 1.8w and whatever you get for each is your key to the expression. So if you were to solve the answers like A you would do 7(1.6+w) and see what you would get. Obviously A isn't the answer. Sorry, this is hard to explain. But the answer is C

A linear function f(x) is shown on the table. What is the value of f(4)

Maksim231197 [3]

F(x)=y

y is considered to be the value of f(x)

Looking at a table, when x=4, the corresponding y value is the value of f(4)

Suppose 0 is an angle in the first quadrant and cos(0) = 1 What is the value of sin(0)?

suter [353]

Answer:

Step-by-step explanation:

I'm going to use a Pythagorean identity to help make this make sense.

$sin^2\theta+cos^2\theta=1$

We are given that cos(0) = 1, so

cos²θ = 1² which simplifies to

cos²θ = 1. So filling into our trig identity:

sin²θ + 1 = 1 and

sin²θ = 0 then

sinθ = √0 so

sinθ = 0

$sin^{-1}\theta=0$ so

sin(0) = 0

What is the slope of (3, 1) and (-3,-2) (remember to use the slope formula y1-y2/x1-x2

vaieri [72.5K]

Answer:

m = 1/2

Step-by-step explanation:

slope = m

m= y1-y2/x1-x2

y1= -2

y2= 1

-2-1 = -3

x1= -3

x2=-3

-3-3 = -6

-3/-6 = 1/2
