For the sequence given by a_n=2n+4 , answer the following:

artcher [175]

a. 6, 8, 10, 12, 14

Work:

a_1 = 2(1) + 4

a_1 = 6

a_2 = 2(2) + 4

a_2 = 8

a_3 = 2(3) + 4

a_3 = 10

a_4 = 2(4) + 4

a_4 = 12

a_5 = 2(5) + 4

a_5 = 14

b. 500

Work:

Since the common difference is 2, we can add 2 to each number until we reach the 20th term.

6 + 8 + 10 + 12 + 14 + 16 + 18 + 20 + 22 + 24 + 26 + 28 + 30 + 32 + 34 + 36 + 38 + 40 + 42 + 44 = 500

A batter strikes a baseball. the equation y = -0.005^2 +0.7x + 3.5 models its path, where x is the horizontal distance, in feet,

hram777 [196]

Answer:

(D)144.8 feet

Step-by-step explanation:

Given the equation which models the path of the baseball

$y = -0.005x^2 +0.7x + 3.5$

where x is the horizontal distance, in feet, the ball travels and y is the height, in feet, of the ball.

To determine how far from the batter the ball will land, we determine the distance x at which the height, y=0.

$y = -0.005x^2 +0.7x + 3.5=0$

$-0.005x^2 +0.7x + 3.5=0$

We use the quadratic formula to solve.

In the quadratic equation above, a=-0.005, b=0.7, c=3.5

$x=\dfrac{-b\pm\sqrt{b^2-4ac} }{2a} \\=\dfrac{-0.7\pm\sqrt{0.7^2-4(-0.005*3.5)} }{2*-0.005} \\=\dfrac{-0.7\pm\sqrt{0.49+0.07} }{-0.01}\\=\dfrac{-0.7\pm\sqrt{0.56} }{-0.01}\\x=\dfrac{-0.7+\sqrt{0.56} }{-0.01} \: or\: x=\dfrac{-0.7-\sqrt{0.56} }{-0.01}\\x=-4.83 \: or\: x=144.83$

Since x cannot be negative, x=144.8 feet to the nearest tenth of a foot.

<u>The correct option is D.</u>

A traveling with thrill rides charges $9 for admission plus $1.50 for each ride you take. If you pay $19.50 total, how many ride

vichka [17]

Answer:

7 rides

Step-by-step explanation:

1. find the amount of money you spent on rides (total money spent - admission fee) = $19.50 - $9 = $10.50

2. find the number of rides you rode (money spent on rides/cost of each ride) = $10.50/$1.50 = 7
