The area of a square garden is 200 m^2. How long is the diagonal?

Sladkaya [172]

Answer:

b. 20 m

Step-by-step explanation:

Let A represent the area

Let d represent the diagonal

then

$A=\frac{d*d}{2} = \frac{d^{2} }{2}$

Then

d² = 2A

then

$d = \sqrt{2A} =\sqrt{2*200} =\sqrt{400} = 20$

The owner of a minor league baseball team has found that when he charges an average of $13.00 per seat, the average attendance i

allsm [11]

Answer:

<u>The correct answer is A. R(d) = -54d2 + 1,269d + 10,530 </u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Price per seat when the average attendance is 810 fans = $ 13

For every $2.00 increase in average ticket price, the attendance decreased by an average of 27 fans per game.

2. Which equation shows the revenue, R, as a function of d, the number of $2.00 increases over $13.00?

R(d) = (13 + 2d) (810 - 27d)

R(d) = 10,530 + 1,620d - 54d² - 351d

R(d) = -54d² + 1,269d + 10,530

<u>The correct answer is A. R(d) = -54d2 + 1,269d + 10,530 </u>

Element X is a radioactive isotope such that every 51 years, its mass decreases by half. Given that the initial mass of a sample

pychu [463]

Answer: It will take 6 years for 7500 grams of X to reach 6900 grams.

Step-by-step explanation:

Expression for rate law for first order kinetics is given by:

$t=\frac{2.303}{k}\log\frac{a}{a-x}$

where,

k = rate constant

t = age of sample

a = let initial amount of the reactant

a - x = amount left after decay process

a) for completion of half life:

Half life is the amount of time taken by a radioactive material to decay to half of its original value.

$51=\frac{0.69}{k}$

$k=\frac{0.69}{51}=0.0135years^{-1}$

b) for 7500 g to reach to 6900 g

$t=\frac{2.303}{0.0135}\log\frac{7500}{6900}$

$t=6years$

It will take 6 years for 7500 grams of X to reach 6900 grams.

At 106°F, a certain insect chirps at a rate of 67 times per minute, and at 108°F, they chirp 83 times per minute. Write an equat

Step2247 [10]

Answer:

$y=8x-781$

Here, $x$ represents temperature and $y$ denotes rate of chirping per minute.

Step-by-step explanation:

Let $x$ represents temperature and $y$ denotes rate of chirping per minute.

At $106$ °F, a certain insect chirps at a rate of $67$ times per minute.

Take $(x_1,y_1)=(106,67)$

At $108$ °F, they chirp $83$ times per minute.

Take $(x_2,y_2)=(108,83)$

Slope intercept form:

$y-y_1=(\frac{y_2-y_1}{x_2-x_1})(x-x_1)$

$y-67=(\frac{83-67}{108-106})(x-106)\\\\y-67=(\frac{83-67}{108-106})(x-106)\\\\y-67=(\frac{16}{2})(x-106)\\\\y-67=8(x-106)\\y-67=8x-848\\y=8x+67-848\\y=8x-781$
