For this case we have that by definition, the area of a triangle is given by:

A = \frac {b * h} {2}

Where:

b: It is the base of the triangle

h: It is the height of the triangle

According to the data of the statement we have:

b = 3 \ units\\h = 4 \ units

Substituting in the formula we have:

A = \frac {3 * 4} {2} = \frac {12} {2} = 6 \ units ^ 2

So, the area of the triangle is6 \ units ^ 2

Answer:

6 \ units ^ 2

What is the point-slope form of a line with slope -5 that contains the point<br> a<br> (2,-1)?
gulaghasi [49]

The point-slope form the line which has the value of slope -5 and contains a point as A(2,-1) is (y+1)=-5(x-2).

<h3>What is point slope form?</h3>

The point slope  form of a line is the expression of line which has a specified slope and passes through a point.

The point slope form is givne as,

(y-y₁)=m(x-x₁)

Here, m is the slope of the line, x₁ is the x coordinate of the point by which line passes and y₁ is the y coordinate of the same point.

The slope of a line is -5. This line contains the point A (2,-1). Thus, the point slope form is,

(y-y₁)=m(x-x₁)

(y-(-1))=-5(x-2)

(y+1)=-5(x-2)

Thus, the point-slope form the line which has the value of slope -5 and contains a point as A(2,-1) is (y+1)=-5(x-2).

Xy=10<br> 4x+2y=30 <br> I need help asap
emmasim [6.3K]

Answer:

x = 25/3; y = -5/3

Step-by-step explanation:

You did well so far by multiplying both sides of the first equation by 2.

Now notice that you have -2y in the new first equation and 2y in the second equation. -2y and 2y add to 0.

Now add the equations to eliminate y.

      2x - 2y = 20

(+)   4x + 2y = 30

-------------------------

      6x         = 50

6x/6 = 50/6

x = 50/6 = 25/3

2x - 2y = 20

2(25/3) - 2y = 20

50/3 - 2y = 60/3

-2y = 60/3 - 50/3

-2y = 10/3

-2y/2 = (10/3)/(-2)

y = -5/3

Solution: x = 25/3; y = -5/3

The water level, measured in feet above mean sea level, of Lake Lanier in Georgia, USA, during 2012 can be modeled by the functi
FrozenT [24]

Answer:

May 4th, 2012.

Step-by-step explanation:

The highest level can be found with the help of the First Derivative and Second Derivative Tests. First and second derivatives of the function are, respectively:

l'(t) = 0.04323\cdot t^{2}-0.8354\cdot t +2.703

l''(t) = 0.08646\cdot t - 0.8354

The First Derivative Tests consists on equalizing the first derivative to zero and finding the critical points.

0.04323\cdot t^{2}-0.8354\cdot t +2.703 = 0

Roots are t_{1} \approx 15.672 and t_{2} \approx 4.077. just the second root offer a realistic solution and is test by the second derivative.

l''(4.077) = -0.482 (which leads to a maximum).

Given that a year has 365 days or 12 months, the highest water level occurs at day:

n = \frac{4.077}{12} \cdot (365\,days)

n \approx 124 (May 4th).
