Answer:

y=x+2

Step-by-step explanation:

the standard form is y=mx+b where m is the slope and b is the y intercept

TO FIND THE SLOPE: we take the x and y intercepts as a fraction. in this case the line touches the y axis (vertical) at point/value 2 and the x axis at point 2 as well. This means the slope is 2/2x which can be simplified to 1x or just x.

TO FIND THE Y INTERCEPT: we find where the line touches the y axis at point 2.

the slope is plugged into the m of the equation and the y intercept is plugged into the b of the equation.

If θ is an angle in standard position that terminates in Quadrant IV such that cosθ = 3/5, then cosθ/2 = _____. -

Sveta_85 [38]

Answer:

$cos \frac{\theta}{2}= 0.894$ .

Step-by-step explanation:

Given:

$cos\ \theta= \frac35$

We need to find $cos \ \frac{\theta}{2}$

Solution:

$cos\ \theta= \frac35$

First we will find the value of $\theta$ .

Now taking $cos^{-1}$ on both side we get;

$\theta= cos^{-1} \ \frac{3}{5}\\\\\theta = 53.13$

Now we will find the $\frac{\theta}{2}$ .

$\frac{\theta}{2}$ = $\frac{53.13}{2} = 26.565$

Now we will find $cos \ \frac{\theta}{2}$ we get;

$cos \frac{\theta}{2}=cos\ 26.565 = 0.894$

Hence $cos \frac{\theta}{2}= 0.894$ .

Answer:

m = 25xd

Step-by-step explanation:

25 per day means multiplication.

first think of just one siberian tiger for d days. that would be 25d because 25 lbs each day.

similarly, one day but x tigers is 25x.

if you have both many tigers and many days, it is 25xd
