A triangle has two equal angles and a smaller angle which measures 26 degrees. What is the measure of one of the larger angles.

A triangle has 3 angles and they always add up to 180 degrees. If the first angle is 26, subtract 26 from 180, which is 154. If the other two angles are equal, divide 154 by two, which is 77. So the other two angles are both 77

180 = 2x + 26
-26 -26
154 = 2x
÷2 ÷2
77 = x
One of the sides is 77

For what value of k is there one solution to the given quadratic equation (k+1)x²+4kx+2=0.

andriy [413]

Answer:

If $k = 1$ or $k = -\frac{1}{2}$ , there is only one solution to the given quadratic equation.

Step-by-step explanation:

Given a second order polynomial expressed by the following equation:

$ax^{2} + bx + c, a\neq0$

This polynomial has roots $x_{1}, x_{2}$ such that $ax^{2} + bx + c = (x - x_{1})*(x - x_{2})$ , given by the following formulas:

$x_{1} = \frac{-b + \sqrt{\bigtriangleup}}{2*a}$

$x_{2} = \frac{-b - \sqrt{\bigtriangleup}}{2*a}$

$\bigtriangleup = b^{2} - 4ac$

The signal of $\bigtriangleup$ determines how many real roots an equation has:

$\bigtriangleup > 0$ : Two real and different solutions

$\bigtriangleup = 0$ : One real solution

$\bigtriangleup < 0$ : No real solutions

In this problem, we have the following second order polynomial:

$(k+1)x^{2} + 4kx + 2 = 0$ .

This means that $a = k+1; b = 4k; c = 2$

It has one solution if

$\bigtriangleup = 0$

$b^{2} - 4ac = 0$

$16k^{2} -8(k+1) = 0$

$16k^{2} - 8k - 8 = 0$

We can simplify by 8

$2k^{2} - k - 1 = 0$

The solution is:

$k = 1$ or $k = -\frac{1}{2}$

So, if $k = 1$ or $k = -\frac{1}{2}$ , there is only one solution to the given quadratic equation.

Alexus [3.1K]

Answer:

$580.13

Step-by-step explanation:

The area of the flooring:

A = 1/2*8*(13.5 - 7.5) + 1/2(8 + 4 + 18)(7.5) = 136.5 ft²

Cost of flooring:

136.5*$4.25 = $580.13

What does f(3) means ?

Butoxors [25]

F(x)=x^2+x+5

then

F(3) would be the function evaluated at x=3, or 17.

anytime you see F(3) it is just whatever formula you are looking at evaluated when the variable is equal to 3.
