Oksi-84 [34.3K]2 years ago
8 0

Answer:

\large\boxed{x=-4\ \vee\ x=7}

Step-by-step explanation:

x^2-3x-28=0\\\\x^2+4x-7x-28=0\\\\x(x+4)-7(x+4)=0\\\\(x+4)(x-7)=0\iff x+4=0\ \vee\ x-7=0\\\\x+4=0\qquad\text{subtract 4 from both sides}\\x=-4\\\\x-7=0\qquad\text{add 7 to both sides}\\x=7

What are the zeros of the function: f(x) = 2x^2-50
yan [13]
When f(x) = 0, 

2x^2 - 50 = 0

2(x^2 - 25) = 0

2(x- 5)(x + 5) = 0

(x - 5) = 0 \ or  \ (x + 5) = 0

x = 5 \ or \ x = -5

--------------------------------
Answer : x = 5 or -5

Which statement correctly compares functions f and g? function f function g An exponential function passes through (minus 1, 5),
slamgirl [31]

A statement correctly compares functions f and g is that: C. they have the same end behavior as x approaches -∞ but different end behavior as x approaches ∞.

<h3>What is a function?</h3>

A function can be defined as a mathematical expression that defines and represents the relationship between two or more variable, which is typically modelled as input (x-values) and output (y-values).

<h3>The types of function.</h3>

In Mathematics, there are different types of functions and these include the following;

  • Periodic function
  • Inverse function
  • Modulus function
  • Signum function
  • Piece-wise defined function.

Function g is represented by the following table and a line representing these data is plotted in the graph that is shown in the image attached below.

x          -1   0   1    2   3   4

g(x)     24  6   0  -2  

Based on the line, we can logically deduce the following points:

  • y-intercept approaches -2.43 to 24.86.
  • x-intercept approaches negative infinity (-∞) to infinity (∞).

This ultimately implies that, a statement correctly compares functions f and g is that both functions have the same end behavior as x approaches -∞ but different end behavior as x approaches ∞.

A car produces 53.9 tons of carbon dioxide over a 7 year period. Find its carbon footprint (tons of carbon dioxide per year).
Marina86 [1]

Answer:

carbon footprint

  7.7 tons

Step-by-step explanation:

Given that,

carbon dioxide produced by a car over 7 year period = 53.5 tons

To find,

carbon footprint <em>(tons of carbon dioxide per year)</em>

7 years ------> 53.5 tons

1 year   -------> 53.9/7 tons

= 7.7 tons

tons of carbon dioxide produced per year = 7.7
