Answer:

70° is your measurement for ∠t.

Step-by-step explanation:

Note that a straight line has an angle of 180°

It is given to us that ∠r and ∠t = 180°, and that m∠r = 110°

Plug in 110 for ∠r

110 + ∠t = 180

Isolate ∠t. Note the equal sign, what you do to one side, you do to the other. Subtract 110 from both sides

110 (-110) + ∠t = 180 (-110)

∠t = 180 - 110

∠t = 70

70° is your measurement for ∠t.

Explain why a triangle can't have two right angles

Sedbober [7]

Answer: They would be a rectangle.

A. Find the first and second derivative of the following function in terms of the parameters c1 and c2.

defon

Answer:

Linear second-order differential equation F(x, y, y′, y″) = 0

y¹¹( -3 x⁴ )+ y¹12 x³ - 12 x² y= 0

Step-by-step explanation:

Step(i):-

Given differential equation

y = c₁x + c₂x⁴ ...(i)

Differentiating equation (i) with respective to 'x', we get

y¹ = c₁(1) + c₂ ( 4 x³ ) ...(ii)

Differentiating equation (ii) with respective to 'x', we get

y¹¹ = c₂ ( 12 x² )

$C_{2} = \frac{y^{11} }{12 x^{2} }$ ...(a)

Step(ii):-

Substitute (a) in equation (ii)

$y^{l} = C_{1} + (\frac{y^{ll} }{12x^{2} } ) (4 x^{3} )$

$C_{1} = y^{l} - (\frac{y^{ll} }{12 x^{2} } ) (4 x^{3} )$ ...(b)

$C_{2} = \frac{y^{11} }{12 x^{2} }$

Step(iii):-

$y = (y^{l} - (\frac{y^{ll} }{12 x^{2} } ) (4 x^{3} ) x + \frac{y^{ll} }{12 x^{2} } x^{4}$

12 x² y = (y¹12 x³ - 4 x⁴ y¹¹) + x⁴ y¹¹

x⁴ y¹¹ - 4 x⁴ y¹¹ + y¹12 x³ - 12 x² y= 0

y¹¹( -3 x⁴ )+ y¹12 x³ - 12 x² y= 0

Laboratory experiment shows that the life of the average butterfly is normally distributed with a mean of 18.8 days and a standa

inessss [21]

Answer:

a) 0.4164

Step-by-step explanation:

Mean lifespan (μ) = 18.8 days

Standard deviation (σ) = 2 days

For any given lifespan 'X', the z-score is:

$z=\frac{X- \mu}{\sigma} \\z=\frac{X- 18.8}{2}$

For X=12.04 days:

$z=\frac{12.04 - 18.8}{2} \\z=-3.38$

A z-score of -3.38 falls in the 0.036-th percentile of a normal distribution.

For X=18.38 days:

$z=\frac{18.38 - 18.8}{2} \\z=-0.21$

A z-score of -3.38 falls in the 41.68th percentile of a normal distribution.

The probability that a butterfly lives between 12.04 and 18.38 days is

$P=41.68-0.036\\P=41.64\%\ or\ 0.4164$
