Answer:

1. x=20 ; the angles are 90 degrees31 degrees 59 degrees

2. x=16; the angles are 16 degrees 92 degrees 72 degrees

Step-by-step explanation:

1. 180=90+31+(3x-1)

180-90-31=3x-1

59=3x-1

60=3x

x=20

plug in x for the third angle

2. 180= x+5x-8+3x+44

180=9x+36

180-36=9x

144=9x

x=16

plug in x to all the angles to find the real value

Find r(t) if r'(t) = 5t4i + 6t5j + t k and r(1) = i + j.

Vladimir [108]

$\mathbf r(t)=\displaystyle\int(5t^4\,\mathbf i+6t^5\,\mathbf j+t\,\mathbf k)\,\mathrm dt$
$\mathbf r(t)=(t^5+C_1)\,\mathbf i+(t^6+C_2)\,\mathbf j+\left(\dfrac12t^2+C_3\right)\,\mathbf k$

Given $\mathbf r(1)=\mathbf i+\mathbf j$ , we have

$\begin{cases}1^5+C_1=1\\\\1^6+C_2=1\\\\\dfrac121^2+C_3=0\end{cases}\implies C_1=0,C_2=0,C_3=-\dfrac12$

so that the particular solution is

$\mathbf r(t)=t^5\,\mathbf i+t^6\,\mathbf j+\dfrac12(t^2-1)\,\mathbf k$

Help Please: Two boats start their journey from the same point A and travel along directions AC and AD, as shown below: What is

Roman55 [17]

Answer:

230.9 ft

Step-by-step explanation:

The side ratios of a 30°-60°-90° triangle are 1 : √3 : 2

In ∆ABC, BC = AB/√3 ≈ 115.47 ft

In ∆ABD, BD = AB√3 ≈ 346.41 ft

Then the length CD is ...

346.41 ft -115.47 ft = 230.94 ft

The distance CD is about 230.9 ft.

Marcus' employee benefits include family health care coverage. He contributes 25% of the cost. Marcus gets paid weekly and $102

ArbitrLikvidat [17]

Monthly amount, M = $102×4 = $408.

Also, yearly amount, Y = M×12 = $408×12 = $4896

It is given that 25% of the cost is contributed by Marcus.

Amount Marcus paid

$=\dfrac{\$4896 \times 25 }{100}\\\\= \$1224$

Therefore, his employer contribution annually for coverage is $( 4896 - 1224)=$3672.

Hence, this is the required solution.
