Please solve and i’ll give u brainliest
Usimov [2.4K]

Solution:

<u>Note that:</u>

  • Given angles: w + 8° and 48°
  • w + 8 + 48 = 180

<u>Solve for w in the equation "w + 8 + 48 = 180".</u>

  • => w + 8 + 48 = 180
  • => 56 + w = 180
  • => w = 180 - 56
  • => w = 124°

The value of w is 124.

If _____, use threshold braking any time you need to brake hard.
Inessa [10]

Answer:

The correct option is;

A. You don't have ABS

Step-by-step explanation:

A car braking system works by the friction action the break pad applies on the wheels, when the break is applied with much force, due to hard and sudden breaking of the motion of the vehicle, the break pad stops the rotation of the wheels but the vehicle could however continue skidding due to the high initial momentum

The being skidding vehicle in a situation of kidding increases the likelihood for an accident as the the vehicle can no longer be controlled at the steering either

Threshold braking is the technique of bringing the vehicle to a stop or slowing down in the shortest time possible by applying an optimum breaking force during breaking

Anti-lock Braking System is a safety feature that prevents skidding by keeping the wheels of the vehicle or aircraft from locking when excessive break is applied such that traction maintained between the wheels and the road.

10 points! How do I factor 8x^2-26x+15
Rufina [12.5K]
<h3><u>(2x - 5)(4x - 3)</u></h3>

The AC method, also known as splitting the middle, can be shown like this:

8x^2 - 26x + 15

<em><u>Check factors of 120.</u></em>

1 * 120

-1 * -120

2 * 60

-2 * -60

3 * 40

-3 * -40

5 * 24

-5 * -24

6 * 20

-6 * -20 (these factors, when added together, are equal to the middle term, and thus splitting the middle term is possible.)

<em><u>Split the middle term.</u></em>

8x^2 - 6x - 20x + 15

<em><u>Group in terms of 2.</u></em>

(8x^2 - 6x) - (20x + 15)

<em><u>Factor each binomial.</u></em>

2x(4x - 3) - 5(4x - 3)

<em><u>Rearrange the terms.</u></em>

(2x - 5)(4x - 3)
