This one actually made me think. I like your teacher.

2h 30min (2.5)×30mph=75m

Find the value of csc theta, if cos =-3/5; 90 degrees < theta < 180 degrees

Sloan [31]

Answer: $\frac{5}{4}$

Step-by-step explanation:

Given

$\cos \theta =\frac{-3}{5}$

and $\theta$ lies between

$90^{\circ}$

and for this $\theta$ , $\sin$ and $\text{cosec}$ is Positive as they lie in 2 nd Quadrant

$\sin ^2\theta +\cos ^2\theta =1$

$\sin ^2\theta =1-(\frac{-3}{5})^2$

$\sin ^2\theta =1-\frac{9}{25}$

$\sin ^2\theta =\frac{16}{25}$

$\sin \theta =\frac{4}{5}$

$\therefore \text{cosec}\ \theta =\frac{5}{4}$

Answer:

The second choice $(7.6,8.8)$

Step-by-step explanation:

The missing image is attached

We use the section formula:

$(x,y)=(\frac{mx_2+nx_1}{m+n},\frac{my_2+ny_1}{m+n})$

We substitute $x_1=3,x_2=16,y_1=2,y_2=21$ and m=5, n=9

$(x,y)=(\frac{5*16+9*3}{5+9},\frac{5*21+5*2}{9+5})$

We simplify to get:

$(x,y)=(\frac{80+27}{14},\frac{105+10}{14})$

This simplifies to:

$(x,y)=(\frac{107}{14},\frac{125}{14})$

In decimals we get:

$(x,y)=(7.6,8.8)$
