Answer:

When the denominator is zero

Step-by-step explanation:

The denominator of any fraction cannot have the value zero. If the denominator of a fraction is zero, the expression is not a fraction because it's value is undefined.but we can have zero as the numerator in a fraction and your answer will be zero.

The denominator of any fraction cannot have the value zero. If the denominator of a fraction is zero, the expression is not a legal fraction because it's overall value is undefined.

Yesterday, the temperature at noon was 43.6 °F. By midnight, the temperature has decreased by 15.3 degrees. What was the tempera

ELEN [110]

Answer:

Temperature at midnight is $-15.9$ °F.

Step-by-step explanation:

Given: The temperature at noon was $43.6$ °F. By midnight, the temperature has decreased by $15.3$ degrees.

To find: The temperature at midnight.

Solution:

The temperature at noon was $43.6$ °F.

Now, by midnight, temperature has decreased by $15.3$ degrees.

So, first we need to convert the temperature in °F.

We know that, $F=\frac{9}{5}C+32$ , where F is temperature in Fahrenheit and C is temperature in Celsius.

So, $F=(\frac{9}{5} \times 15.3)+32$

$\implies F=59.5$

So, by midnight, temperature has decreased $59.5$ °F

Therefore, temperature at midnight is $43.6-59.5=-15.9$ °F

Hence, temperature at midnight is $-15.9$ °F.

Can someone help me for question 18 pls? I really need help to solve this question!!

Plug the x-values from the table into the given equation and solve for y.

y = 5 - x²

First column

replace x with -2

y = 5 - (-2)²

= 5 - (4)

= 1

(x, y) = (-2, 1)

Second column

replace x with -1

y = 5 - (-1)²

= 5 - (1)

= 4

(x, y) = (-1, 4)

Third column

replace x with 0

y = 5 - (0)²

= 5 - (0)

= 5

(x, y) = (0, 5)

Fourth column

replace x with 1

y = 5 - (1)²

= 5 - (1)

= 4

(x, y) = (1, 4)

Fifth column

replace x with 2

y = 5 - (2)²

= 5 - (4)

= 1

(x, y) = (2, 1)

St lies on the coordinate plane with s located at (3.2). The midpoint of dt is z(3,9) state the location of the endpoint T thank

77julia77 [94]

Answer:

T = (3,16)

Step-by-step explanation:

The midpoint formula is just another version of the pythagorean theorem, and it states that the midpoint between (x1,y1) and (x2,y2) is $\left(\frac{x_1+x_2}{2}\right),\:\left(\frac{y_1+y_2}{2}\right)$

Substituting what we know:

endpoint S is (3,2) and endpoint T is (x2,y2)

Midpoint Z is (3,9). We will apply the formula -- backwards.

$\left(\frac{3+x_2}{2}\right)=3$ , solving with algebra we get x2 = 3

So the x-coordinate of endpoint T is 3.

$\left(\frac{2+y_2}{2}\right)=9\quad$ , solving with algebra, we get y2 = 16.

So the y-coordinate of endpoint T is 16.

So the location of endpoint T is (3,16)
