Let u = <7, -3>, v = <-9, 5>. Find 4u - 3v.
Katyanochek1 [597]

Answer:

a.<55, -27>

Step-by-step explanation:

The given vectors are u = <7, -3>, v = <-9, 5>.

We want to find 4u - 3v.

We substitute the vectors and multiply by the scalars.

4u - 3v=4<7, -3>-3 <-9, 5>.

4u - 3v=<28, -12>- <-27, 15>.

4u - 3v=<28--27, -12-15>

4u - 3v=<55, -27>

What is the length of side BC of the triangle? Enter your answer in the box. units Triangle A B C with horizontal side B C. Vert
harina [27]

Answer:

The length of BC = 28 units

Step-by-step explanation:

* In triangle ABC

∵ Angles B and C are congruent

∴ m∠B = m∠C

* In any triangle if two angles are equal in measure, then the triangle is isosceles means the two sides which opposite to the congruent angles are equal in length

∴ AB = AC

∵ AB = 4x - 7

∵ AC = 2x + 7

∴ 4x - 7 = 2x + 7 ⇒ collect like terms

∴ 4x - 2x = 7 + 7

∴ 2x = 14 ⇒ divide both sides by 2

∴ x = 14 ÷ 2 = 7

* Now we can find the length of BC

∵ The length of BC = 4x ⇒ substitute the value of x

∴ The length of BC = 4 × 7 = 28 units

Joan likes 20% of her female friends and there are total of 110 female friends

20% 110 would be➡ 110 ÷ 100 × 20 = 22
