Answer: Celsius scale

Step-by-step explanation:

Fahrenheit scale is established from the freezing and boiling temperatures of water, which are:

Freezing temperature of water: $32\°F$

Boiling temperature of water: $212\°F$

Which means that all temperatures below $32\°F$ are below the freezing temperature of water. Therefore, if Jen is in the Summer season, which is characterized by high temperatures, it is incoherent to think that the thermometer is using the Farenheit scale.

Now, $30\°C$ is in accordance with the high temperatures recorded in the summer season.

If we want to know how much $30\°C$ is in Farenheits, we must use the following conversion formula:

$(30\°C)(\frac{9}{5})+32=86\°F$

This table gives a few (x, y) pairs of a line in the coordinate plane. What is the x-intercept of the line?

PIT_PIT [208]

Answer:

Step-by-step explanation:

The x-intercept of a line is the value of x that makes y=0.

A line can be expressed in its slope-intercept form:

y=mx+b

Once determined the equation of the line, the x-intercept can be calculated by setting y=0 and solving for x.

Let's find the slope of the line.

Suppose we know the line passes through two points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:

$\displaystyle m=\frac{y_2-y_1}{x_2-x_1}$

Let's pick the first two points of the table (-94,24) (-74,18). The slope is:

$\displaystyle m=\frac{18-24}{-74+94}=\frac{-6}{20}=-\frac{3}{10}$

The equation of the line is:

$\displaystyle y=-\frac{3}{10}x+b$

Now use one of the points to find b, for example (-94,24):

$\displaystyle 24=-\frac{3}{10}\cdot (-94)+b$

Operating:

$\displaystyle 24=\frac{141}{5}+b$

Solving:

$b=24-\frac{141}{5}=-\frac{21}{5}$

The complete equation of the line is:

$\displaystyle y=-\frac{3}{10}x-\frac{21}{5}$

To find the x-incercept, set y=0 and solve:

$\displaystyle 0=-\frac{3}{10}x-\frac{21}{5}$

$\displaystyle x=\frac{\frac{21}{5}}{-\frac{3}{10}}=-\frac{21}{5}\cdot \frac{10}{3}$

x=-14

Weak battery is considered to be a part of routine

grandymaker [24]

Answer:

A. wear and tear

Step-by-step explanation:

A battery is generally expected to become weaker over time, as a consequence of the normal use of equipment. The presence of a weak battery would be found by a routine check, and replaced by routine maintenance.

The fact that a battery is weak would be considered the result of routine wear and tear
