I am just completely lost and am unsure of how to approach this problem.

Ipatiy [6.2K]

Answer:47

Step-by-step explanation: sum of angles in a straight is 180

Aob +Box =180

6x+29+3x+124 =180

9x + 153 = 180

9x =27

x= 3

Boc =6*3 +29

Boc = 47

If you borrow $500 from a credit union at 12% annual interest and $250 from a bank at 18% annual interest, what is the effective

Gnesinka [82]

Answer:

B. 11.85% = 12%

Step-by-step explanation:

500 * .10 + 300 * .15 = 50 + 45 = 95.

95/800 = .11875

.11875 = 11.875%

The temperature at a point (x, y, z) is given by T(x, y, z) = 300e−x2 − 3y2 − 7z2 where T is measured in °C and x, y, z in meter

Answer:

Rate of change $24^{\circ}$ C per meter.

Step-by-step explanation:

Given,

$T(x,y,z)=300e-x_{2}-3y_{2}-7z_{2}$

Then,

$T_{x_2}=-1, T_{y_2}=-3, T_{z_2}=-7$

Change of temperature at the point say, $(x,y,z)=(2,-1,3)$ along the direction say, $(u,v,w)=(6,-4,6)$ is,

$\Big[uT_{x_2}+vT_{y_2}+wT_{z_2}\Big]_{(x,y,z)}$

$=(6\times -1)+((-4)\times (-3))+(3\times 6)$

= $24$

Hence the rate of change of temperature is $24^{\circ}$ C per meter.
