Answer:

C x= 85°

Step-by-step explanation:

x+ 60° + 35° =180°

Answer:

85°

Step-by-step explanation:

Show that the known angles can be transferred to the triangle via corresponding angles and vertical angles

Sum of interior triangle angles is 180

x = 180 - 60 - 35 = 85

Evaluate the spherical coordinate integral

expeople1 [14]

Rewrite the equations of the given boundary lines:

y = -x + 1 ==> x + y = 1

y = -x + 4 ==> x + y = 4

y = 2x + 2 ==> -2x + y = 2

y = 2x + 5 ==> -2x + y = 5

This tells us the parallelogram in the x-y plane corresponds to the rectangle in the u-v plane with 1 ≤ u ≤ 4 and 2 ≤ v ≤ 5.

Compute the Jacobian determinant for this change of coordinates:

$J=\begin{bmatrix}\frac{\partial u}{\partial x}&\frac{\partial u}{\partial y}\\\frac{\partial v}{\partial x}&\frac{\partial v}{\partial y}\end{bmatrix}=\begin{bmatrix}1&1\\-2&1\end{bmatrix}\implies|\det J|=3$

Rewrite the integrand:

$-3x+4y=-3\cdot\dfrac{u-v}3+4\cdot\dfrac{2u+v}3=\dfrac{5u+7v}3$

The integral is then

$\displaystyle\iint_R(-3x+4y)\,\mathrm dx\,\mathrm dy=3\iint_{R'}\frac{5u+7v}3\,\mathrm du\,\mathrm dv=\int_2^5\int_1^45u+7v\,\mathrm du\,\mathrm dv=\boxed{333}$

Find the cost of sending a telegram which has 34words if the cost of the first ten words is4050$and the cost of each extra word

Stells [14]

Answer:

The final cost would be $42,780 for sending a 34 word telegram.

Step-by-step explanation:

1. $4050*10= $40,500

2. 34-10=24

3. 24*$95= $2,280

4. $40,500+$2,280= $42,780

PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!!

Alenkasestr [34]

Answer:

A = -10

Step-by-step explanation:

x^2 + 10x + 24 = 0

To find the roots, we need to factor the equation.

What 2 numbers multiply to 24 and add to 10

6*4 = 24

6+4 = 10

(x+6) (x+4)=0

Using the zero product property

x+6 = 0 x+4 = 0

x = -6 x = -4

We want the sum when the roots are added

-6+ -4 = -10
