Answer:

1. A

2. D

Step-by-step explanation:

1. Interior opposite angles are equal to 180⁰ therefore y + x = 180⁰

2. Alternate angles are equal

like if you see the letter Z, N, M or W, the angles are alternate. Like here it is letter Z.

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

1<br> Select all relations that are functions from the choices below

Daniel [21]

Answer:

Option (D).

Step-by-step explanation:

If the graph of a relation has two output values for a single input value, relation will not be considered to be a function.

Option (A).

For the input values of x = -1, there are two output values, y = -1, 1.

Therefore, given relation is not a function.

Option (B).

Since, all the parabolas don't represent a function, given parabola in the graph is not a function.

Option (C).

Not a function. It's a relation.

Option (D).

Line plotted in the graph has a distinct output value for every input value.

Therefore, the given graph represents a linear function.
