Answer:

Option (3) and Option (5)

Step-by-step explanation:

Alice invested $13 in the first month.

Then she deposits $25 every month.

Therefore, sequence formed by the deposit will be an arithmetic sequence.

First term of the sequence will be,

A_1=13

Since, recursive formula formula of a sequence is given by the formula,

A_n=A_{(n-1)}+d

Where 'd' = common difference in each term of the sequence

Recursive formula for the sequence will be,

A_n=A{(n-1)}+25

Since, explicit formula for the arithmetic sequence is represented by the formula,

A_n=A_1+(n-1)d

where n = number of term

d = common difference

Therefore, nth term of the sequence formed will be represented by the explicit formula,

A_n=13+(n-1)25

A_{10}=13+(10-1)25

      = 13 + 225

      = 238

A_{8}=13+(8-1)25

     = 188

A_{12}=13+(12-1)25

      = 288

Therefore, Option (3) and Option (5) will be the answer.

Answer:

<h2>C</h2>

Step-by-step explanation:

using the pythagorian theorem, we know that a^2+b^2=c^2. inputting the numbers into this equation, we get

8^2+23^2=c^2

then, using our big math brains, we get 64+529=c^2

adding together the numbers, we end up with 593

just take the sqyare root of that and bada bing bada boom! you get 24.35, or 24.4, therefore the answer is C

A golf ball is hit off a tee toward the green. The height of the ball is modeled by the function h(t) = −16t2 + 96t, where t equ
Ierofanga [76]

Answer:

t = 3; It takes the ball 3 seconds to reach the maximum height and 6 seconds to fall back to the ground.

Step-by-step explanation:

To find the axis of symmetry, we need to find the vertex by turning this equation into vertex form (this is y = a(x - c)² + d where (c, d) is the vertex). To do this, we can use the "completing the square" strategy.

h(t) = -16t² + 96t

= -16(t² - 6t)

= -16(t² - 6t + 9) - (-16) * 9

= -16(t - 3)² + 144

Therefore, we know that the vertex is (3, 144) so the axis of symmetry is t = 3. Since the coefficient of the squared term, -16, is negative, it means that the vertex is the maximum. We know that it takes the golf ball 3 seconds to reach the maximum height (since the t value of the vertex is 3) and because the vertex is on the axis of symmetry, it would take 3 more seconds for the ball to fall to the ground, therefore it takes 3 + 3 = 6 seconds to fall to the ground. The final answer is "t = 3; It takes the ball 3 seconds to reach the maximum height and 6 seconds to fall back to the ground.".
