What is the solution to this inequality 10 X +18 < -2? A--x>-2. B--x <-2. C--x>2 D--x < 2

Answers

Answer 1
To solve this problem we start with the following 10x+18<-2. Then we will minus 18 off both sides leaving us with 10x<-20. We can now divide by 10 giving us x<-2. So the answer is B

Answers

Answer:

71° F

Step-by-step explanation:

Consider the rational part of f(t)

[tex]\frac{40t^3}{t^3+100}[/tex]  ( divide numerator and denominator by t³

= [tex]\frac{40}{1+\frac{100}{t^3} }[/tex]

As t → infinity then [tex]\frac{100}{t^3}[/tex] → 0 , the expression simplifies to

[tex]\frac{40}{1+0}[/tex] = [tex]\frac{40}{1}[/tex] = 40

Thus after driving for a long time

f(t) = 31 + 40 = 71° F

i need help quick plssss

Answers

Answer:

140°

Step-by-step explanation:

∠ABC is an inscribed angle and its measure is half the measure of the intercepted arc, which is arc AC

Therefore the measure of arc AC is 2(70) = 140°

∠AOC is a central angle and its measure is equal to its intercepted arc, which is arc AC.

So, m∠AOC = 140°

The angle AOC from the given circle is 140°. Therefore, option C is the correct answer.

What is relation between angle at the center and the angle at the circumference?

The angle subtended by an arc at the center is twice the angle subtended at the circumference. More simply, the angle at the center is double the angle at the circumference.

From the given circle, angle ABC is 70°.

Here, 2∠ABC=∠AOC

∠AOC=2×70°

∠AOC=140°

Therefore, option C is the correct answer.
