Explanation:
___________________________________________________________
Given the quadratic function:
___________________________________________________________
→ " y = (x <span>− 8) (x + 3) " ; </span>← Note: Replace the "f(x)" with: "y" ;
→ Find the "y-intercept".
___________________________________________________________
→ Note: The "y-intercept" is the coordinate of the point(s) of the graph of the equation at which the graph crosses the "x-axis" when "x = 0" .
→ So; we set plug in "0" for "x" into our equation; and solve for "y" ;
→ " y = (x − 8) (x + 3) " ;
→ y = (0 − 8) (0 + 3) ;
→ y = (-8) * (3) ;
→ y = - 24 ;
___________________________________________________________
So, the "y -intercept" of the <em><u>given</u></em> quadratic function is:
the point at which: "x = 0 ; y = -24 " ;
→ that is; the point the coordinates: " (0, - 24) " ;
___________________________________________________________
→ which is: Answer choice: [C]: " (0, - 24) " .

Is about the same as the posting you had before.
bear in mind that in an exponential equation the initial amount is usually the one outside the parentheses, the one that doesn't have an exponent
128(0.50)ˣ, that'd be 128.
I am almost positive that the answer is the first one.
Answer:
tan(B)
Step-by-step explanation:
we know that
The tangent of an angle is equal to divide the opposite side to the angle by the adjacent side to the angle
In this problem
tan(B)=AC/AB
substitute
tan(B)=8/15
The current when the resistance is 10 ohms is 24 amps
<h3>What are variations?</h3>
Variations are simply data that change in values (i.e. not constant)
<h3>Types of variation</h3>
The types of variations are:
- Direct variation
- Inverse variation
- Joint variation
- Combine variation
From the complete question (see attachment), we have the following highlights
- The variation is an inverse variation
- When current (I) is 30 amps, the resistance (R) is 8 ohms
An inverse variation is represented as:
Where k represents the constant of variation.
The above equation can be rewritten as:
So, we have:
When the resistance is 10 ohms, we have:
Divide both sides by 10
Rewrite the above equation as:
Hence, the current when the resistance is 10 ohms is 24 amps
