If a 45 gal hot water tank holds 375 lb of water, what weight of water will a 62 gal tank hold

Answers

Answer:

517 lb

Step-by-step explanation:

Hello,thanks for asking here in brainly I think I can help you with this

you can easily solve this by using a rule of three

Step one

45 gal⇒ 375 lb

62 gal ⇒ x lb?

do the relation

$(45\ gal)/(375\ lb)=(62\ gal)/(x)\n\nsolve\ for\ x\n\n\n(x*45\ gal)/(375\ lb)=62\ gal\nx=(62\ gal*375\ lb)/(45\ gal) \nx=516.66\ lb\nx=517\ lb$

the weight of water holded in a 62 gal tank is 517 lb

I hope it helps, Have a great day.

Assume you drop a rock from a cliff which is 5000 feet above the ground. The distance in feet, y, of the rock below the cliff at the time t seconds after it was dropped is given by the equationY=-1/2gt^2

Answers

Answer:

Step-by-step explanation:

Given that height of cliff H = 5000 ft

You drop rock from cliff and the distance of rock below the cliff at time,t is given by:

$y= -(1)/(2) gt^(2)$

Q1. How far below the cliff is the rock 7 seconds after it dropped ?

Ans. Here, t=7 seconds

By using formula provide, g=32.18 ft{tex] $s^(-2)$

y=- \frac{1}{2} × 32.17 × (7)^{2}[/tex] = 788.165 ‬ft

Note: Negative sign shows the direction and 240.345 is magnitude

Therefore, Rock is 788.165‬ ft from Cliff

Q2. How far is the rock from the bottom 7 seconds after it dropped ?

By using formula provide,

Ans. After 7 seconds, Rock is 788.165‬ ft from Cliff

Therefore, Rock is 5000-788.165‬ = 4,211.835 ft from bottom

Q3. When will rock hit the bottom?

Ans. Height of cliff H= 5000 ft

Using formula provided, g=32.18 ft $s^(-2)$

$y = -(1)/(2) gt^(2)$

$-5000 = - (1)/(2) 32.18 × t^(2)$

$t^(2) = (5000×2)/(32.18)$

$t^(2) = 311.13876$

$t = 17.6s$

Q4. The Velocity of the rock at impact?

Ans. Velocity is given as V= g×t

By using formula, We get

V= 32.14 × Total time to reach ground

V= 32.14 × 17.6 = 565.66 ft/s

Consider the following function. f ( x ) = 1 − x 2 / 3 Find f ( − 1 ) and f ( 1 ) . f ( − 1 ) = f ( 1 ) = Find all values c in ( − 1 , 1 ) such that f ' ( c ) = 0 . (Enter your answers as a comma-separated list. If an answer does not exist, enter DNE.) c = Based off of this information, what conclusions can be made about Rolle's Theorem? This contradicts Rolle's Theorem, since f ( − 1 ) = f ( 1 ) , there should exist a number c in ( − 1 , 1 ) such that f ' ( c ) = 0 . This does not contradict Rolle's Theorem, since f ' ( 0 ) = 0 , and 0 is in the interval ( − 1 , 1 ) . This does not contradict Rolle's Theorem, since f ' ( 0 ) does not exist, and so f is not differentiable on ( − 1 , 1 ) . This contradicts Rolle's Theorem, since f is differentiable, f ( − 1 ) = f ( 1 ) , and f ' ( c ) = 0 exists, but c is not in ( − 1 , 1 ) . Nothing can be concluded.

Answers

Answer:

(E)Nothing can be concluded.

Step-by-step explanation:

Given the function $f(x)=1-x^{(2)/(3)}$

$f(-1)=1-(-1)^{(2)/(3)}=1.5-0.86603i\nf(1)=1-1^{(2)/(3)}=1-1=0$

$f'(x)=-(2)/(3)x^{-(1)/(3)}\nf'(x)=-\frac{2}{3\sqrt[3]{x} }$

If the derivative is set equal to zero, the function is undefined.

Nothing can be concluded since $f(1)\neq f(-1)$ and no such c in (-1,1) exists such that $f'(c)=0$

THEOREM

Rolle's theorem states that any real-valued differentiable function that attains equal values at two distinct points must have at least one stationary point somewhere between them—that is, a point where the first derivative is zero.

Final answer:

The function f(x) = 1 - x^2/3 has f(-1) = f(1) = 2/3. The derivative f'(x) = -2x/3 equals zero at x=0, which is in the interval (-1, 1). Therefore, this does not contradict Rolle's Theorem.

Explanation:

The function given is f ( x ) = 1 - x ^ 2 /3. To find the values f(-1) and f(1), we simply substitute these values into the function. Therefore, f(-1) = 1 - (-1) ^ 2 /3 = 1 - 1/3 = 2/3 and f(1) = 1 - 1^2/3 = 2/3. As you can see, f(-1) = f(1).

Now, to find the value 'c' such that f'(c) = 0, first we need to determine the derivative of the function, f'(x) = -2x/3. Setting this equal to zero gives the equation 0 = -2x/3, which has the solution x = 0. Therefore, f'(c) = 0 at c = 0, which is within the interval (-1, 1).

Finally, regarding Rolle's Theorem which states that if a function is continuous on the closed interval [a, b], differentiable on the open interval (a, b), and f(a) = f(b), then there exists at least one c in the interval (a, b) such that f'(c) = 0, our results are consistent with Rolle's Theorem, since f is differentiable, f(-1) = f(1), and a 'c' value exists in the interval (-1, 1) such that f'(c) = 0.

When the Chili restaurant chain was in ﬁnancial trouble.its CEO directed the managers of each of the chain's restaurant to trim costs without sacriﬁcingcustomer satisfaction.Which of the following did the CEO use to make restaurant managers accountable for cost-cutting measures?A) substitution8) transpositionC) delegation of authorityD) job sharing

Answers

Answer: Option C : delegation of authority

Step-by-step explanation:

the CEO used DELEGATION OF AUTHORITY approach to make restaurant managers accountable for cost-cutting measures in the above case.

Final answer:

The CEO of the Chili restaurant chain used the delegation of authority principle to make restaurant managers responsible for cost-cutting measures without sacrificing customer satisfaction.

Explanation:

In the situation described, the Chili restaurant chain's CEO used delegation of authority to make restaurant managers accountable for cost-cutting measures. Delegation of authority refers to the process of passing down responsibilities and decision-making power from upper to lower levels of management. In this case, the CEO entrusted the restaurant managers with the responsibility of reducing costs, while also maintaining customer satisfaction. Using this strategy, the CEO was able to shift accountability to the managers, who now have the authority to manage their resources and strategize their cost-cutting measures in a manner that would not compromise the level of satisfaction of their customers.
