A football team started at the line of scrimmage. On the first play of the drive, the team lost 4 yards. On the second play of t

he drive, the team gained 45 yards. Taylor calculated |–4 – 45| = |–49| = 49, and said that the team gained a total of 49 yards on the two plays. Which best describes Taylor’s error?
A. Taylor did not find the correct distance between –4 and 45.

B. Taylor did not make an error. The team gained a total of 49 yards on the two plays.

C. Taylor correctly found the distance between –4 and 45, but this number represents the team’s total loss, not the team’s total gain.

D. Taylor correctly found the distance between –4 and 45, but this number represents the total distance the team moved in both directions, not the team’s total gain.

The base of pyramid A is a rectangle with a length of 10 meters and a width of 20 meters. The base of pyramid B is a square with
ollegr [7]
Given:
Pyramid A: Base is rectangle with length of 10 meters and width of 20 meters.
Pyramid B: Base is square with 10 meter sides.
Heights are the same.

Volume of rectangular pyramid = (L * W * H) / 3
Volume of square pyramid = a² * h/3

Let us assume that the height is 10 meters.
V of rectangular pyramid = (10m * 20m * 10m)/3 = 2000/3 = 666.67 m³
V of square pyramid = (10m)² * 10/3 = 100m² * 3.33 = 333.33 m³

The volume of pyramid A is TWICE the volume of pyramid B.

If the height of pyramid B increases to twice the of pyramid A, (from 10m to 20m),  

V of square pyramid = (10m)² * (10*2)/3 = 100m² * 20m/3 = 100m² * 6.67m = 666.67 m³

The new volume of pyramid B is EQUAL to the volume of pyramid A.

Describe how to transform the graph of f into the graph of g. f(x) = square root of quantity x minus nine. and g(x) = square roo
ruslelena [56]

Answer:

Translate the graph 14 units horizontally to the left by adding to the x-variable the constant 14.

Step-by-step explanation:

Translations of "c" units in the horizontal axis are obtained by adding or subtracting the constant value "c" to the variable x itself. When we want to translate the graph to the right, we subtract c, and when we want to move the graph horizontally to the left , we add c.

In this case, to go from the radicand (x-9) to the radicand (x+5), an addition of 14 units has to be performed, and such corresponds to a horizontal displacement to the left in 14 units.

When a test for steroids is given to soccer players, 98% of the players taking steroids test positive and 12% of the players not
anygoal [31]

Answer:

P = 0.300 or 30%

Step-by-step explanation:

There are two possibilities for a player to test positive:

1-) He does not take steroids (95%) with a 12% chance of testing positive:

P= 0.95 x 0.12

2-) He does take steroids (5%) with a 98% chance of testing positive:

P= 0.05 x 0.98

So the probability that a player tests positive is:

P = 0.95 x 0.12 + 0.05 x 0.98 =0.163

Therefore, the probability that a soccer player who tests positive takes steroids is:

P= \frac{0.05 * 0.98 }{0.163}\\P=0.300

Samir is trying to decide between two checking account plans. After researching plans at two banks, he finds that Unity Bank off
GREYUIT [131]

Answer:

The monthly compounded interest rate of 0.14% of Unity Bank is a better plan.

Step-by-step explanation:

<em>Step 1 : Write the formula for calculating a monthly compound interest rate and for calculating an annually compounded interest rate.</em>

Monthly compound interest rate = P(1+r/n)^nxt

<em>n=12 (number of months in a year)</em>

<em>t=1 (number of years)</em>

Annually compound interest rate = P(1+r/n)^nxt

<em>n=1 (because it is for 1 year only)</em>

<em>t=1 (number of years=1)</em>

<em>Step 2 : Lets assume that P is $100 in both banks and time is 1 year.</em>

<em>Step 3 : Lets substitute the values to find out which one is better.</em>

Monthly compound interest rate = P(1+r/n)^nxt

Monthly compound interest rate = 100(1+0.14/12)^12x1

Monthly compound interest rate = 114.93

114.93 - 100 = $14.93 per month

14.93 x 12 = $179.16 for 12 months or 1 year

Annually compound interest rate = P(1+r/n)^nxt

Annually compound interest rate = 100(1+1.6/1)^1x1

Annually compound interest rate = 260

260-100 = $160 for 1 year

Therefore, the monthly compounded interest rate of 0.14% of Unity Bank is a better plan.
