It is supplementary angle
(3X+25)+(2x)=180
5x+25=180
-25. -25
5x=155
/5. /5
X=31

Supplementary, because both of the measurements are on a straight line which is equal to 80 degrees and x is equal too 31

Answer:

146°

Step-by-step explanation:

Blue angle: 34°: 180 (sum of angles in a triangle) - 92 - 54 = 34

x = 180 (flat angle) - 34 = 146°

Answer:

As x decreases without bound, f(x) increases without bound

As x increases without bound, f(x) approaches 0

Step-by-step explanation:

As x gets more and more negative f(x) gets bigger and bigger

f(x) = (7/10) ^ x but x is negative so flip it and then x is a larger number

(10/7) ^ large number so it will get larger

as → -∞ f(x) →∞

As x gets more and more positive f(x) gets smaller and smaller

f(x) = (7/10) ^ x closer and closer to 0. The denominator gets larger faster than the numerator = 1 / large number

as → ∞ f(x) →0

How to Simplify Rational Expressions?

IceJOKER [234]

To simplify rational expressions, simply see and check if there is a common number or same number that can be divided from in both. If not here, you would simply multiply the numbers together.

Then simplify if you would need to.

It would be 85x/6

Answer:

a) r(t) = 0.783t radians

b) h(t) = 30cos(0.783*t) feet

Step-by-step explanation:

The situation is depicted in the picture attached

<h3>(see picture) </h3>

Since the angular speed is constant, to find an expression for the angle r(t) in radians we just cross-multiply using the fact that 1 min = 60 seconds

4.7 radians __________ 60 seconds

r(t) radians ____________ t seconds

$\large \displaystyle\frac{4.7}{r(t)}=\displaystyle\frac{60}{t}\Rightarrow r(t)=(4.7/60)t \Rightarrow\\\\\boxed{r(t)=0.783t\;rad}$
