3 0

Answer:

-4(8x-7)/7

Step-by-step explanation:

1. Simplify Term.

-8/7 (4x) - 8/7 * -3 + 4/7

-32x/7 - 8/7 * -3 + 4/7

-8/7 * 3

-32x/7 + 24/7 + 4/7

2. Simplify Term.

− 32 x *  24  + 4 divided by 7

-32x + 28 divided by 7

4(-8x + 7) divided by 7

4(-(8x) + 7) divided by 7

3. Rewrite 7 as -1(-7)

4(-(8x) - 1(-7)) divided by 7

4(-(8x - 7)) divided by 7

4. Rewrite -(8x - 7) as -1(8x - 7)

4(-1(8x - 7)) divided by 7

-4(8x - 7)/7

An auto weighing 2,500 pounds is on a street inclined at 10 with the horizontal. Find the force necessary to prevent the car fro
Misha Larkins [42]

Answer:

1931.7N

Step-by-step explanation:

We are told in the question that :

An auto ( a car) weighs = 2500 pounds

It s inclined at n horizontal Ange of 10°

We are asked to find the force that would prevents it from rolling down the street.

Since the unit for Force = Newton or kgm/s²

Step 1

Convert Weight in pounds to kg

1 pound = 0.453592kg

2500 pounds =

2500 pounds × 0.453592kg

= 1133.981kg

Step 2

Find the force that would prevents it from rolling down the street.

Force = Mass × Acceleration due to gravity × sin θ

Acceleration due to gravity = 9.81m/s

Force = 1133.981kg × 9.81 × sin 10°

Force = 1931.7237321 N

Approximately = 1931.7N

Is sqrt(1 - sin^2 θ) = cos θ true? if so, in which quadrants does angle θ terminate?​
jonny [76]

Answer:

  I and IV

Step-by-step explanation:

Since 1-sin(θ)² = cos(θ)², the given equation is equivalent to ...

  √(cos(θ)²) = |cos(θ)| = cos(θ)

This will be true where the cosine is non-negative, in the first and fourth quadrants.
