The half life of a decaying substance is defined as the time at which the substance decreases to one-half of its original value. In this case, given  hlf-life of 10 years and an original mass of 50 grams, after 10 years, the isotope mass becomes 50*0.5 or 25 grams. Answer is B.

Zander was given two functions: the one represented by the graph and the function f(x) = (x + 4)2. What can he conclude about th
Svetradugi [14.3K]

The conclusion about the functions is they have the same y-intercept.

<h3>How to make conclusion about the functions?</h3>

The complete question is added as an attachment

The function is given as:

f(x) = (x + 4)^2

From the attached graph, the graph has a y-intercept at:

y = 16

This can be represented as:

(0, 16)

Next, we set x = 0 in f(x) = (x + 4)^2

f(0) = (0 + 4)^2

Evaluate

f(0) = 16

This means that the y-intercept of f(x) = (x + 4)^2 is (0, 16)

So, the functions have the same y-intercept

Hence, the conclusion about the functions is they have the same y-intercept.

The label on the car's antifreeze container claims to protect the car between −40°C and 140°C. To covert Celsius temperature to
telo118 [61]

Answer:

-40

Step-by-step explanation:

We must convert the given temperatures from degrees Celsius to degrees Fahrenheit

The formula is:

C=\frac{5}{9}(F-32)

Where C is the temperature in degrees Celsius and F is the temperature in degrees Fahrenheit

Then we must replace the temperature in degrees Celsius and solve the equation for F

C*\frac{9}{5}=(F-32)

F=C*\frac{9}{5}+32

F=(-40)*\frac{9}{5}+32

F=-40\ \°F

F=(140)*\frac{9}{5}+32

F=284\ \°F

The Fahrenheit temperature range in which the antifreeze protects the car is:

-40
