1 answer:
gulaghasi [49]3 years ago
8 0

Answer:

12.4cm

Step-by-step explanation:

Circumference of a circle: \pi d where d is the diameter.

Therefore circumference of a quarter circle (just the arc): \frac{1}{4} \pi d

Arc AB = \frac{1}{4} *\pi * (2*7.9) since Diameter = 2 times of Radius

Arc AB = \frac{1}{4}*3.14*15.8 = 12.4cm (rounded to the nearest tenth)

Given vector u = (3, 1) and v = (2,-4), determine the value of v – 4u in<br> component form.
igomit [66]

Answer:

(-10, -8)

Step-by-step explanation:

4u

Each component of vector u is multiplied by 4. So

u = (3, 1)

4u = (4*3, 4*1) = (12,4).

v – 4u

Subtraction of the components of vector v by the components of the vector 4u. So

v - 4u = (2, -4) - (12, 4) = (2-12, -4 - 4) = (-10, -8)

The value is (-10, -8)
