In ΔRST, r = 5 cm, t = 6.8 cm and ∠T=23°. Find all possible values of ∠R, to the nearest 10th of a degree.
8090 [49]

Answer:

\angle r=16.696

Step-by-step explanation:

From the question we are told that:

Dimension

r = 5 cm

t = 6.8 cm

∠T=23°

Generally the equation of sine rule i is mathematically given by

\frac{sin \angle r}{R} =\frac{sin \angle t}{T}

\frac{ \angle r}{1} =sin^-^1(\frac{sin \angle t*R}{T})

\frac{ \angle r}{1} =sin^-^1(\frac{sin23*5}{6.8})

\angle r=16.696

An object traveling with an initial constant speed along the y-axis begins to decelerate 4 kilometers before reaching a referenc
balandron [24]

The value that is equal to the average rate of change of the function over the interval is equal is 1 m/s

<h3>The average rate of change</h3>

Given the position of the object expressed as:

y = -t^2 + 3t - 4

In order to calculate the value that is equal to the average rate of change of the function over the interval (0, -4) and (2, -2), we will determine the slope of these two coordinates as shown;

Rate of change = -2-(-4)/2-0
Rate of change = -2+4/2
Rate of change = 2/2

Rate of change = 1 m/s

Hence the value that is equal to the average rate of change of the function over the interval is equal is 1 m/s

Please help me solve this using the distance formula!!
kumpel [21]

Answer:

51.5 m

Step-by-step explanation:

Plot the points B and C. Then substitute the points in the distance formula.

B(-35,-20)  

\sf x_1= -35 \  ; \ y_1=-20

C(-10,25)

\sf x_2=-10 \ ; \ y_2 = 25

        \sf \boxed{\bf Distance = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}}

                          \sf = \sqrt{(-10-[-35])^2+(25-[-20])^2}\\\\=\sqrt{(-10+35)^2+(25+20)^2}\\\\=\sqrt{(25)^2+(45)^2}\\\\=\sqrt{625+2025}\\\\=\sqrt{2650}\\=51.5 \ m
