The prediction is 193.86 lb.

Substituting 73 for x, we have:

-102.3923 + 4.0582*73 = 193.86

Answer:

x=16 * cos(46)

Step-by-step explanation:

Well, first let's look at our trig identities. We can set up a cosine function using the given angle:

cos (46^{o} ) = \frac{x}{16} (adjacent/hypotenuse)

Then, multiplying both sides by 16 gives us:

x=16 * cos(46)

Hope this helps!

3. Determine which ordered pair is not a solution of y = –5x – 4.
erastovalidia [21]

Answer:

A

Step-by-step explanation:

Let's try choice A.

y = -5x-4

(10, -52)

-52 = -5(10)-4

-52 = -50-4

-52= -54

-52 is not equal to -54, so A is the answer.

Bao is mixing flour and water to make dough. The graph shows how much water he uses for different amounts of flour.
Butoxors [25]

Answer:

0.33 liters of water Bao use per liter of flour.

3  liters of flour Bao use per liter of water

Step-by-step explanation:

Given the graph which pass through the coordinates (0,0) and (3,1)

∴ Equation of line passing through these points can be written as

(y-y')=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}(x-x')

⇒  (y-0)=\frac{1-0}{3-0} (x-0)

⇒ y=\frac{1}{3}x ⇒ 3y=x

Now, we have to find liters of water Bao use per liter of flour i.e if x=1 then we find the value of y which is 3y=x=1 ⇒ y=\frac{1}{3} = 0.33 l

Now, we have to find  liters of flour Bao use per liter of water i.e if y=1 the we have to find the value of x which is x=3 litre
