Mathematics

Domain: all real numbers, since no number can make this function undefined
Range: since this an upward opening parabola(because the quadratic coefficient is positive), and the minimum point is 23, the range is going to be any number equal or greater than 23.

A hiker cycles 9 miles in 2/3 of an hour. Make a chart and fill it in to show how far he will bike if he maintains the same pace
Arada [10]

Answer:

2 hours: 27 miles, 3 hours: 40.5 miles, 3.5 hours: 47.25 miles

Step-by-step explanation:

1.) If a hiker hikes 9 miles in 2/3 of an hour, he will hike 4.5 (Half of 2/3 is 1/3 and half of 9 is 4.5) miles in 1/3 of an hour and 13.5 miles per hour. (1/3 times 3 gives us a whole and 4.5 times 3 is 13.5)

2.) 2 hours: 13.5 * 2 = 27 miles

3.) 3 hours: 13.5 * 3 = 40.5 miles

4.) 3.5 hours: 13.5 * 3.5 = 47.25 miles

Helloo!!! please help me on this !!!!
ivann1987 [24]

It is given that ️PQR & ️UVW are congruent to each other. According to CPCT, the corresponding angles in 2 triangles willl have the same measure. So, ∠R = ∠W, i.e, (10x - 18)° = 8x°

\mathfrak{10x - 18 = 8x}

\mathfrak{10x - 8x = 18}

\mathfrak{2x = 18}

\mathfrak{x = \dfrac{18}{2}}

\underline{\mathfrak{x = 9}}

Measure of ∠R :

\mathfrak{8x}

\mathfrak{8(9)}

\boxed{\mathfrak{72^{\circ}}}
