Help please!!

Mathematics
1 answer:
Damm [24]3 years ago
5 0

Step-by-step explanation:

I think you mean that 10 cm³ of air are escaping every second.

and we start with a volume of 500 cm³.

V = 500 - 10t 0 <= t <= 50

because negative t (seconds) don't make any sense, and neither does a negative volume (for t > 50).

A calculator is required to obtain the final answer on this question. A solid metal sphere at room temperature 20oC is dropped i
yKpoI14uk [10]

Answer:

T = 47.1875°C

Step-by-step explanation:

Given:

Surrounding temp, Ts = 100°C

Initial Temperature ,T0= 20°C

Increase in temperature = 15°C

Final temperature, T = 20 + 15 = 35°C

Time, t = 9 seconds

Let's take Newton's law of cooling:

T - Ts = (T_0 - Ts)e^k^t

We'll solve for k

35 - 100 = (20 - 100)e^9^k

-65 = (-80)e^9^k

Divide both sides by -5

13 = (16)e^9^k

9k = ln (\frac{13}{16})

k = \frac{1}{9} ln (\frac{13}{16})

k = -0.02307104053

Let's now find the temperature of the ball after 18 seconds in boiling water.

Use the Newton's equation again:

T - Ts = (T_0 - Ts)e^k^t

T - 100 = (20 - 100)e^-0.0^2^3^0^7^1^0^4^0^5^3^*^1^8

T - 100 = (-80)e^-0.0^2^3^0^7^1^0^4^0^5^3^*^1^8

T - 100= -52.8125

T = 100 - 52.8125

T = 47.1875°C

Temperature of the ball after 18 seconds in boiling water is 47.1875°C

,Line segment PQ is shown on a coordinate grid:
Marina86 [1]

Answer:

P'Q' is equal in length to PQ.

Step-by-step explanation:

Before rotation

P(-5, 3)

Q(-1, 3)

we get the length

L = √((-1-(-5))²+(3-3)²) = √((-4)²+(0)²) = 4

After rotation

P'(3, 5)

Q'(3, 1)

we get the length

L' = √((3-3)²+(1-5)²) = √((0)²+(-4)²) = 4

we can say that   L = L' = 4

P'Q' is equal in length to PQ.
