$\text{Given that,}\\\\(x_1,y_1) = (0,0)~~ \text{and}~~ (x_2, y_2) = (-12,5)\\\\\text{Distance between two points,}\\\\d=\sqrt{(x_2-x_1)^2 + (y_2-y_1)^2}\\\\\implies d = \sqrt{(-12-0)^2 + (5-0)^2}\\\\\implies d = \sqrt{(-12)^2 +5^2}\\\\\implies d =\sqrt{144+25}\\\\\implies d=\sqrt{169}\\\\\implies d = 13\\\\\text{So, the answer is C.}$

slega [8]

We are 114.28 m from the base of the plateau .

<u>Step-by-step explanation:</u>

Here we have , suppose that you are headed toward a plateau 80 meters high. if the angle of elevation to the top of the plateau is 35 degree, WE need to find that how far are you from the base of the plateau . If we see in question , it's clearly a question from application of trigonometry :

We have ,

$Perpendicular = 80 m$

$Base = x$

$Angle = 35 = \alpha$ ( between base & hypotenuse )

It's a right angled triangle , So

$tan\alpha = \frac{Perpendicular}{base}$

⇒ $tan\alpha = \frac{Perpendicular}{base}$

⇒ $tan35 = \frac{80}{x}$

⇒ $x = \frac{80}{tan35}$

$tan35 = 0.7$

⇒ $x = \frac{80}{0.7}$

⇒ $x = 114.28m$

Therefore, We are 114.28 m from the base of the plateau .

soybean meal is 18% protein, cornmeal is 19% protein.. how many pounds of each should be mixed in order to get 360lb mixture tha

seraphim [82]

S=weight of soybean protein, C=weight of cornmeal protein.
Total weight of each protein is 0.18S+0.19C=0.17×360=61.2 lb.
Total weight of meal is S+C=360 lb. So S=360-C.
Therefore 0.18(360-C)+0.19C=61.2, 64.8-0.18C+0.19C=61.2, 0.01C=-3.6.
Clearly we would get a negative value for C. When you look at the question you will realise that there is a larger percentage of protein in the ingredients than there is in the mixture. The expected amount of protein in the mixture should be between 18% and 19%. Please check your figures.

If (x+3) varies directly as y and x=3 when y=12, what is the value of x when y=8?

slavikrds [6]

Answer:

x = 1.

Step-by-step explanation:

y = k(x + 3)

When x = 3 y = 12 so

12 = k(3 + 3)

6k = 12

k = 2.

So the relation is y = 2(x + 3)

When y is 8:

8 = 2(x + 3)

2x = 8 - 2*3 = 2

x = 1.
