keeping in mind that there 60 seconds in 1 minute, and about 1.609 kilometers in 1 mile.

$\bf \cfrac{3.8~\underline{km}}{\underline{sec}}\cdot \cfrac{mi}{1.609~\underline{km}}\cdot \cfrac{60~\underline{sec}}{min}\implies \cfrac{3.8\cdot 60~mi}{1.609~min}~~\approx~~141.7029~\frac{mi}{min}$

Precal : Note: Triangle may not be drawn to scale. Suppose a = 3 and A = 15 degrees

drek231 [11]

Given:

In a right triangle at B,

$\begin{gathered} a=3 \\ A=15^{\circ} \end{gathered}$

To find:

The length of the sides b and c and angle B.

Explanation:

Using the trigonometric ratio,

$\begin{gathered} sinA=\frac{a}{c} \\ \sin15^{\circ}=\frac{3}{c} \\ c=\frac{3}{\sin15^{\circ}} \\ c=11.59 \\ c\approx11.6 \end{gathered}$

Using the trigonometric ratio,

$\begin{gathered} \tan A=\frac{a}{b} \\ \tan15^{\circ}=\frac{3}{b} \\ b=\frac{3}{\tan15^{\circ}} \\ b=11.19 \\ b\approx11.2 \end{gathered}$

Using the angle sum property,

The angle B becomes,

$\begin{gathered} 90+15+B=180 \\ B=180-90-15 \\ B=75^{\circ} \end{gathered}$

Final answer:

The values are,

$\begin{gathered} b=11.2 \\ c=11.6 \\ B=75^{\circ} \end{gathered}$

Randy has 2 tennis balls, 6 marbles, and 1 orange in his desk. What generalization can you make about these things

Lubov Fominskaja [6]

You can't eat them nor are they same size
the numbers don't seem to matter

they all seem to be round or spherical
I generalize that they all should be able to roll since they are spheres

Answer:

$\large\boxed{B.\ a^2+2ah+h^2+3a+3h+5}$

Step-by-step explanation:

$f(x)=x^2+3x+5\\\\f(a+h)\to\text{substitute}\ x=a+h\ \text{to the equation:}\\\\f(a+h)=(a+h)^2+3(a+h)+5\\\\\text{Use}\ (x+y)^2=x^2+2xy+y^2\ \text{and the distributive property}\\\\f(a+h)=a^2+2ah+h^2+3a+3h+5$
