Step-by-step explanation:

CHECK THE COMPLETE QUESTION BELOW

Whitney deposits $9,000 for two years. She compares two different banks. State Banks will pay her 4.1% interest, compounded monthly. Kings Savings will pay her 4.01% interest, compounded continuously.Which bank pays higher interest? How much higher?

The Amount in the formula for compound interest is

A= P(1+r)^2

P = principal amount,

r = rate per periods,

t = number of periods,

To know the interest she got from the State bank, we say

P = $ 9000, r = 4.1% = 0.041, t = 2 years,

A= 9000(1+0.041)^2

A= 9000(1.041)^2

= 9767.74

Then interest earned = A - P

= 9767.74 - 9000

= $ 767.74

To know the interest she got from the State bank, we say

P = $ 9000, r = 4.01% = 0.0401, t = 2 years,

A= 9000(1+0.0401)^2

A= 9000(1.0401)^2

= 9751.53

Then interest earned = A - P

= 9767.74 - 9000

= $ 751.53

The difference between the two interest is ($ 767.74 - $ 751.53)

=$16.21

Hence state bank will have $16.21 higher interest

Simplify the following expression as much as possible (3+I)-(5-7i)(-2+2i

Pavel [41]

Answer:

- 1 - 23i

Step-by-step explanation:

The expression is

(3+i)-(5-7i)(-2+2i)

The answer to your question can be found in the image attached below.

We need to multiply the terms and add them together

(3+i) - [ (5)(-2+2i) +(-7i)(-2+2i) ]

= (3+i) - [ -10 +10i + 14i -14i^2]

= (3+i) - [ -10 +10i + 14i +(14)]

= (3+i) - [ 4 + 24i ]

= (3+i) - 4 - 24i

= - 1 - 23i

Question Which ordered pairs are solutions to the equation 2x+10y=12? Select all that apply. Select all that apply: (7,−2) (−5,−

AveGali [126]

Answer:

C and D

Step-by-step explanation:

To determine which pairs are solutions, substitute the coordinates into the left side of the equation and if equal to the right side then they are solutions.

(7, - 2)

2(7) + 10(- 2) = 14 - 20 = - 6 ≠ 12 → (7, - 2) is not a solution

(- 5, - 4)

2(- 5) + 10(- 4) = - 10 - 40 = - 50 ≠ 12 → (- 5, - 4) is not a solution

(4, $\frac{2}{5}$ )

2(4) + 10( $\frac{2}{5}$ ) = 8 + 4 = 12 → hence solution

(- 5, $\frac{11}{5}$ )

2(- 5) + 10( $\frac{11}{5}$ ) = - 10 + 22 = 12 → hence solution

Triangle DEF is congruent to GHJ by the SSS theorem. Which rigid transformation is required to map DEF onto GHJ?

kondaur [170]

Answer: The correct option is 4, i.e., translation.

Explanation:

It is given that the triangle DEF is congruent to GHJ by the SSS theorem.

From the given figure it is noticed that the triangle DEF and GHI are isosceles triangle.

Reason for correct option:

In transition the side and angles of the shape are not effected and the figure transfers from one place to another place without making any other change.

Since the both triangle are congruent and the position of all sides and angles are same, therefore option 4 is correct.

Reason for incorrect option:

In dilation the size of the figure is either stretched or compressed according to the scale factor k. But in the given figure the size of both triangles are same it means option A is incorrect.

In reflection the distance of all the point in preimage and all the image are same from the central line. Any central line does not exist in given figure. SO, the option B is incorrect.

In rotation the side length and angles are not affected but the position are not same, therefore the option C is incorrect.
