Answers
Answer:
2.8a²+0.9a - 1.2
Step-by-step explanation:
Given the expression 0.3(3a-4)-0.05(8a)(-7a)
Expand using the distributive law
0.3(3a-4)-0.05(8a)(-7a)
0.3(3a)-0.3(4)-0.05(8a)(-7a)
0.9a-1.2 - 0.05(8a)(-7a)
0.9a - 1.2 + 2.8a²
Rearrange
2.8a²+0.9a - 1.2
Hence the required expression is 2.8a²+0.9a - 1.2

Answer:
v = <-5, 1> ≈ <5.09902, 168.69°>
Step-by-step explanation:
Vector u has its tail at the origin, so the coordinates of its head give you the components of the vector. To find the components of vector v, you can translate it so its tail is at the origin, or you can simply subtract the tail coordinates from the head coordinates.
v = <1, -2> -<6, -3> = <1-6, -2-(-3)>
v = <-5, 1>
As you know, the magnitude is the root of the sum of the squares of the components:
|v| = √(5²+1²) = √26 ≈ 5.09902
The tangent of the angle is the ratio of y to x coordinates. When using the arctangent function, the quadrant needs to be taken into account.
∠v = arctan(1/-5) ≈ 168.69°
Vector v is ...
v = <-5, 1> ≈ <5.09902, 168.69°>
Which equation can be used to solve for x in the

(3x + 12)
Choose 1 answer:
3x + 12) + x = 180
(3x + 12) = x
3x = 180 + x
(3x + 12) + x = 90
Answers
The expression used to solve for x will be 3x + 12) + x = 180. The correct option is A.
What is the supplementary angle?The angle is defined as the span between two intersecting lines or surfaces at or close to the point where they meet. The angles having the sum of 180 degrees will be called supplementary angles.
Given that there are two angles one is 3x + 12 and the other is x separated by the inclined line on the horizontal line.
From the supplementary angle property, the sum of the two angles is equal to 180 degree.
3x + 12 + x = 180
Therefore, the expression used to solve for x will be 3x + 12) + x = 180.

Consider harmonic oscillators with mass m, spring constant k, and damping coefficient b. For the values specified,
a. write the second-order differential equation and the corresponding first-order system.
b. find the eigenvalues and eigenvectors of the linear system.
c. classify the oscillator (as underdamped, overdamped, critically damped, or undamped) and, when appropriate, give the natural period.
d. sketch the phase portrait of the associated linear system and include the solution curve for the given initial condition.
Answers
Answer:
a) attached below
b) Eigen values : λ1 = -1 and λ2 = - 1/2
Eigenvector : V1 = - y1 and V2 = ( - 1/2 ) y2
c) since the Oscillator is > 0 hence it is Overdamped
Step-by-step explanation:
Lets take : m = 2 , k = 1 and b = 3
a) Second -order differential equation and the first order system
attached below
b) determine the eigenvalues and eigenvectors of the Linear system
Eigen values : λ1 = -1 and λ2 = - 1/2
Eigenvector : V1 = - y1 and V2 = ( - 1/2 ) y2
attached below is the detailed solution
c) The oscillator is classified as OVERDAMPED
To determine if the oscillator is damped, underdamped, or overdamped we will apply the relation below
b^2 - 4km
( 3 )^2 - 4(1)(2) = 1
since the Oscillator is > 0 hence it is Overdamped
d) Attached below is the phase portrait of the associated linear system

The chamber of commerce for a beach town asked a random sample of city-dwellers, "Would you like to live at the beach?” Based on this survey, the 95% confidence interval for the population proportion of city-dwellers who would like to live at the beach is (0.56, 0.62).
Based on this poll, a chamber of commerce member claims that more than half of city-dwellers would prefer to live at the beach.
Use the confidence interval to evaluate this claim and select the true statement.
Yes, it is reasonable to assume this because all reasonable values in the confidence interval are greater than 0.50.
We cannot determine this without taking a census of all city-dwellers.
No, it is not reasonable to assume this because another 95% confidence interval might not be entirely above 0.50.
No, it is not reasonable to assume this because there are only two choices and the proportion of city-dwellers who should prefer either is exactly 0.50, not more than 0.50.

Pippa's bank account pays 2.5% compound interest per annum and her bank
balance is £3200. After 3 years, how much will Pippa's bank balance be?
Answers
Answer:
£3446.05
Step-by-step explanation:
the interest for the first year
=£3200×2.5%
=£3200×2.5/100
=£80
the balance
=£3200+£80
=£3280
the interest for the second year
=£3280×2.5%
=£3280×2.5/100
=£82
the balance
=£3280+£82
=£3362
the interest for the third year
=£3362×2.5%
=£3362×2.5/100
=£84.05
the balance
=£3362+£84.05
=£3446.05
