Answer:

12 trips

Step-by-step explanation:

219 - 45 = 174

174 ÷ 14.5 = 12 (trips)

you subtract 45 from 219 because she will make that amount of points no matter what, then you divide to show the total amount of trips she needs to take

What is the value of x
RideAnS [48]

Answer:

x=5

Step-by-step explanation:

We can use the Triangle Angel Bisector Theorem


AB             2x-1

----------= --------------

AC               3x

9              2x-1

----------= --------------

15               3x


Using cross products

3x*9 = 15*(2x-1)

Distribute

27x = 30x-15

Subtract 30x from each side

27x-30x = 30x-30x-15

-3x = -15

Divide by -3

-3x/-3 =-15/-3

x =5

Complex numbers zj and zz are given by zj = 3- j2, zz = - 4 + j3. (a) express zj and zz in polar form. (b) find lz1l by first ap
inna [77]

Solution:

Given: zj = 3- j2, zz = - 4 + j3

Part a:

zj = 3- j2 = 3.6e^{-j33.7^{\circ}}

zz = - 4 + j3 = 5e^{j143.1^{\circ}}

Part b:

|zj| = |3− j2| =  √3² +(−2)² = √13 = 3.60

|z1| =  √(3− j2)(3+ j2) = √ 13 = 3.60.

Part c:

With the help of part a:

z1z2 = 3.6e^{-j33.7^{\circ}}.5e^{j143.1^{\circ}}
