A central angle θ in a circle of radius 5 m is subtended by an arc of length 6 m.

Marina86 [1]

Answer:

θ=1.2 rad=68.7549°

Step-by-step explanation:

Given

Circle of radius 5
Arc of length 6 subtends angle of θ

$\text{Arc Length}=\text{Radius}\times \text{Angle Subtented(in rad)}$

⇒

$6= 5\times \text{O}\\$

θ $=\frac{6}{5} =1.2rad$

Therefore θ=1.2 rad

(π rad= 180°)

Therefore 1.2 rad= 68.7549°

Suppose researchers marked 800 turtles and later were able to trap a total of 300 individuals in that population, of which 150 w

aleksklad [387]

The estimate for the total population size is 1600.

Setting up a proportion for this, we know that 150 out of our 300 turtle sample is marked; this is the first ratio for the proportion. We also know that we marked 800 of our total population, which we will call x:

150/300 = 800/x

Cross multiply:
150*x = 300*800
150x = 240000

Divide both sides by 150:
150x/150 = 240000/150
x = 1600

What types of solutions will a quadratic equation have when the discriminant b2 − 4ac in the quadratic formula is a perfect squa

netineya [11]

<em>The discriminant must be zero.</em>

Step-by-step explanation:

A Perfect-Square Trinomial is given by the form:

$(\alpha x \pm \beta)^2=(\alpha^2x^2 \pm 2\alpha x \beta + \beta^2)$

The discriminant in the quadratic formula is:

$\Delta=b^2-4ac \\ \\ \\ Here: \\ \\ a= \alpha^2 \\ \\ b=2\alpha \beta \\ \\ c=\beta^2 \\ \\ \\ So: \\ \\ \Delta=(2\alpha \beta )^2-4(\alpha^2)(\beta^2) \\ \\ \Delta=4\alpha^2 \beta^2-4\alpha^2 \beta^2=0$

So in order to get a perfect square,<em> the discriminant must be zero.</em>
