Answer:

Option E. None of these.

Step-by-step explanation:

A merchant paid $3 each for golfing hats and sold for $4 each. He earned a gross profit of $1 per hat.

We have to calculate the percent of increase in cost price Or percentage profit.

Percentage profit = $\frac{\text{(Selling price - Cost price)}}{\text{cost price}}(100)$

= $\frac{(4-3)}{3}.(100)$

= $\frac{100}{3}=33.33$ %

Which not in any option.

Therefore, Option E. None of these is the answer.

Answer:

a) y = 9.187 * 1.09899^x

b) 2647.2695

Step-by-step explanation:

a) using calculator, (mine is ti84 plus ce), we use stat and edit. we plug in x and y. x will be in the L1 and y wil be in L2. Now, we go to stat, calc, and we press ExpReg, short for exponential regression. we calculate and get y = 9.187 * 1.09899^x

you can round if you want. well, i guess you shouldn't, cuz it changes it dramatically

b) Now, we use y = 9.187 * 1.09899^x into the y= and we put it in whatever slot we want. Now, we press trace. we press 60 to find the y,because the number is always x. the number , y, we want is 2647.2695 recommendations.

Mei and Anju are sitting next to each other on different horses on a carousel. Mei's horse is 3 meters from the center of the

SOVA2 [1]

Answer:

$2\pi \approx 6.28\ meters$

Step-by-step explanation:

Mei's horse is 3 meters from the center of the carousel. After one rotation, Mei travelled

$l_M=2\pi r=2\pi \cdot 3=6\pi\ meters$

Anju's horse is 2 meters from the center. After one rotation, Mei travelled

$l_A=2\pi r=2\pi \cdot 2=4\pi\ meters$

The difference in their travelled distances is

$l_M-l_A=6\pi -4\pi =2\pi \approx 6.28\ meters$

I would set all 3 given measures equal to 180.
13x-9+4x+11+2x+7 = 180
19x +9 = 180
19x = 171
x= 9

angle l = 4 (9) + 11= 47

An engineer is designing an arch-shaped gate for the entrance to an amusement park. The gate must be 80 feet wide and 25 feet ta

Tom [10]

1) the form of the equation may be written as y = A(X - Xo)(X - X1)

Where Xo and X1 are the two roots of the equation.

2) We can fix the system of coordinates so that the vertex is in the middle of the gate => Xo = - 40 and X1 = +40

=> y = A (X + 40) (X - 40) = A (X^2 - 1600)

3) The height, at X = 0 is 25

=> A(0 - 1600) = 25

=> -1600A = 25 => A = -25 / 1600 = - 1/64

4) The equation is y = - [1/64] (X^2 - 1600)

5) You can present it in different equivalent forms.

Some of those other forms are:

1) - 64y = (x^2 - 1600)

2) x^2 = - 64y + 1600

3) X^2 = - 64 (y - 25)
