We have (1,4) + (-1,-4) = (0,0), because 1 + (-1) = 1 - 1 = 0 and 4 + (-4) = 4 - 4 = 0.

Solve: 22,440=6,200e^0.06T 22,440=6,200e^0.1T

Tomtit [17]

Answer:

$22440=6200e^{0.06T}$

$\implies \dfrac{561}{155}=e^{0.06T}$

$\implies \ln\dfrac{561}{155}=\ln e^{0.06T}$

$\implies \ln\dfrac{561}{155}=0.06T$

$\implies T=\dfrac{50}{3}\ln\dfrac{561}{155}$

$\implies T=21.43826314...$

$22440=6200e^{0.1T}$

$\implies \dfrac{561}{155}=e^{0.1T}$

$\implies \ln\dfrac{561}{155}=\ln e^{0.1T}$

$\implies \ln\dfrac{561}{155}=0.1T$

$\implies T=10\ln\dfrac{561}{155}$

$\implies T=12.86295789...$

Answer:

Part 1 : Equation: ( 3x - 9 ) + 30 + 24 = 180,

Part 2 : Value of x ⇒ 45°,

Part 3 : Measure of Angle U ⇒ 126°

Step-by-step explanation:

~ Part 1 ~

We know that ∑ of angles in a triangle is 180;

m∠ U + m∠ V + m∠ W = 180°,

Equation: ( 3x - 9 ) + 30 + 24 = 180

~ Part 2 ~

Now let us simplify the equation above to solve for x;

3x - 9 + 30 + 24 = 180,

3x - 9 = 126,

3x = 135,

x = 45 degrees ( ° ) ⇒

Value of x ⇒ 45°

~ Part 3 ~

If it is known that m∠ U ⇒ 3x - 9;

m∠ U = 3 * ( 45 ) - 9,

m∠ U = 135 - 9,

m∠ U = 126 degrees ( ° ) ⇒

Measure of Angle U ⇒ 126°
