A sequence can be generated by using an = 4a(n - 1), where a1 = 6 and n is a whole
krek1111 [17]

Answer:

First four terms are: 6 , 24 , 96 , 384

Step-by-step explanation:

a₁ = 6

an = 4a(n-1)

a₂ = 4* a₍₂₋₁₎ = 4 * a₁ = 4*6 = 24

a₃ = 4*a₍₃₋₁₎ = 4  * a₂ = 4 * 24 = 96

a₄ = 4* a₍₄₋₁₎ = 4 * a₃ = 4 * 96 = 384

Mr. Jenkins deposited $4,250 into an account. He made no additional deposits or withdrawals. Mr. Jenkins earned 2.25% annual sim
LekaFEV [45]

Answer:

$4,823 75cents

Step-by-step explanation:

First we need yo calculate the interest on amount deposited after 6years.

Using the formula for calculating simple interest as shown;

SI = Principal × Rate × Time/100

Given

Principal = amount deposited = $4,250

Rate = 2.25%

Time = 6years

SI = 4,250×2.25×6/100

SI = 57,375/100

SI = $573.75

Amount after 6years = Principal+Interest

= $4,250+$573.75

= $4823.75

Hence the balance in dollars and cents in Mr. Jenkins's account at the end of 6 years is $4,823 75cents

Question<br> Example<br> Step by Step<br> In kite ABCD, mZBAE = 28° and mZBCE = 58°. Find mLABE.
Bad White [126]

Answer:

m\angle ABE=52^\circ

Step-by-step explanation:

<u>Angles and Lines</u>

The figure shows a kite ABCD where the following data is given:

m\BAE=28^\circ

m\BCE=58^\circ

We also know

BC\cong CD

AB\cong AD

Since triangle BCD is isosceles, it follows that:

m\angle CBE=m\angle CDE

And triangles BCD and DCE are congruent.

Thus:

m\angle BCE=m\angle DCE=58^\circ

And also:

m\angle BCE=58^\circ+58^\circ=116^\circ

Since the sum of internal angles of BCD is 180°

m\angle CDE=m\angle CBE= ( 180 - 116 ) / 2=32^\circ

The sum of angles of triangle CDE is 180°, thus

m\angle CED=180^\circ - 32^\circ - 58^\circ = 90^\circ

Angles CED and BEA are vertical (opposite), thus:

m\angle BCE=m\angle CED= 90^\circ

Finally, since the sum of the angles of triangle ABE is 180°

m\angle ABE= 180 - 90 - m\angle BAE

m\angle ABE= 180^\circ - 90^\circ - 28^\circ = 52^\circ

\mathbf{m\angle ABE=52^\circ}
