Answer:

P(t) = 1161(9)^{t}

Step-by-step explanation:

Given

P(t) = 43(3)^{2t+3}

Required

Write in form of P(t) =ab^t

P(t) = 43(3)^{2t+3}

Apply law of indices:

P(t) = 43(3)^{2t}*3^3}

Reorder

P(t) = 43*3^3*(3)^{2t}

Express 3^3 at 27

P(t) = 43*27*(3)^{2t}

P(t) = 1161*(3)^{2t}

Rewrite as:

P(t) = 1161*(3^2)^{t}

Express 3^2 as 9

P(t) = 1161*(9)^{t}

P(t) = 1161(9)^{t}

Mary got a piggy bank as a gift with X cents in it. If she saves Y cents each month for a year, how much money will she have in
-BARSIC- [3]

Answer:

The total money she saved in a year = X + 12Y.

Step-by-step explanation:

Mary got a piggy bank as a gift.

Sum of money in the piggy bank while she got it as a gift = X cents

Sum of money she saved = Y cents per month

1 year = 12 months

So, sum of money she saved in 1 year = Y × 12

= 12Y

Hence, the total money she saved in a year = X + 12Y.

Factor the following equation to find its zeros. y = x² - 36
alukav5142 [94]

Answer:

x = 6, x = - 6

Step-by-step explanation:

Given

y = x² - 36

To find the zeros let y = 0, that is

x² - 36 = 0 ← x² - 36 is a difference of squares and factors in general as

a² - b² = (a - b)(a + b), thus

x² - 36 = 0

x² - 6² = 0

(x - 6)(x + 6) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 6 = 0 ⇒ x = 6

x + 6 = 0 ⇒ x = - 6

Figure ABCD is a rhombus where the m∠ABC = 84 and m∠ABE = 3x − 6. Solve for x. Rhombus ABCD with diagonals AC and BD and point E
bazaltina [42]

Answer:

<u> x = 16</u>

Step-by-step explanation:

See the attched figure

We should know that, one of the properties of the rhombus is the diagonals bisect the angles of the rhombus.

Given:

m∠ABC = 84  and m∠ABE = 3x − 6

So, m∠ABE = 0.5 * m∠ABC = 0.5 * 84 = 42

∴ 3x - 6 = 42

Solve for x

3x = 42 + 6 = 48

x = 48/3 = 16

<u>∴ x = 16</u>
