Y= 2x-1 is a tangent to y=x^2. Name the point of tangency,

lubasha [3.4K]

Answer:

Point of tangency is $x=1$ or $(1,1)$

Step-by-step explanation:

You don't really need to use Calculus here. You can just set each equation to each other and solve for x (the point of tangency):

$x^2=2x-1$

$x^2-2x+1=0$

$(x-1)(x-1)=0$

$x=1$

Therefore, the point of tangency is $x=1$ or $(1,1)$

A triangular plot of land has one side along a straight road measuring 147147 feet. A second side makes a 2323degrees° angle wit

ch4aika [34]

Answer:

81.23 ft and 77.88 ft long

Step-by-step explanation:

The sum of the internal angles of a triangle is 180 degrees, the missing angle is:

$a+b+c=180\\a+23+22=180\\a=135^o$

According to the Law of Sines:

$\frac{A}{sin(a)}= \frac{B}{sin(b)}= \frac{C}{sin(c)}$

Let A be the side that is 147 feet long, the length of the other two sides are:

$\frac{A}{sin(a)}= \frac{B}{sin(b)}\\B=\frac{sin(23)*147}{sin(135)}\\B=81.23\ ft\\\\\frac{A}{sin(a)}= \frac{C}{sin(c)}\\C=\frac{sin(22)*147}{sin(135)}\\C=77.88\ ft$

The other two sides are 81.23 ft and 77.88 ft long

Help and explain I can't get this wrong

Alexxandr [17]

I'm assuming we're solving for x.

One property of a straight line is that the angles that make a straight line have to add up to 180 degrees.

Given this information, we know that 4x + 5 + 41 = 180
4x + 46 = 180
4x = 134

x = 134/4 = 33.5
