The final score in the video game is 67.
Step-by-step explanation:
Points earned = 50 points, 87 points
Points lost = 40 points, 30 points
Let,
Plus sign (+) represent the points earned.
Negative sign (-) represent the points lost.
Therefore,
Points earned = +50, +70
Points lost = -40, -30
Adding all the points to get final score;
Final score = 50+(-40)+87+(-30)
The final score in the video game is 67.

Let us calculate the total cost first. Since each book costs 8$ and we have 6 books, we need to multiply 6 by 8 to get the total cost, hence 48$. We the need to calculate the reduction; 20% *48=9.6$. This is the reduction. To calculate the net cost, we need to subtract the reduction from the total cost. Hence, net cost= 48-9.6=38.4$

15m
Explicación paso a paso:
Dada la expresión de la altura de la pelota lanzada modelada por la ecuación;
h (x) = -5x² + 10x + 15
El momento en que se arrojó la piedra es cero, es decir, x = 0 segundos
Sustituya x = 0 en la ecuación y encuentre h (x) como se muestra;
h (x) = -5x² + 10x + 15
h (0) = -5 (0) ² + 10 (0) +15
h (0) = 0 + 0 + 15
h (0) = 15 m
De ahí que la altura de la piedra cuando la arrojes sea de 15 m
