Answer: The required expression she is on after d days is 
Step-by-step explanation:
Since we have given that
Page number at which she is = 88
Number of pages she will read every day = 20
Let the number of days be 'x'.
According to question, it becomes
Hence, the required expression she is on after d days is
Answer:
The factored form of 16m²-9 = (4m+3)(4m-3)
Step-by-step explanation:
16m²-9
To find the factors of the expression, first you have to find out the perfect square of the terms:
4 is the perfect square of 16
∴4 is the number if multiplied two times wil give the product of 16.
m is the perfect square of m²
3 is the perfect square of 9
Then,
16m2-9 = (4m)² - (3)²
Now apply the perfect square formula:
a² - b² = (a+b)(a-b)
Therefore,
(4m)² - (3)² = (4m+3)(4m-3)
Thus the factored form of 16m²-9 = (4m+3)(4m-3) ....
Answer: la altura es 13.1 m
Step-by-step explanation:
El movimiento descripto es de tipo rectilineo uniformemente variado, más precisamente tiro vertical.
Para calcular la posición al cabo de 1 seg utilizaremos la ecuacionecuación del movimiento descrita como:
y = v0.t - 1/2 g t^2
Donde y es la altura para cualquier momento
v0 es la velocidad inicial 18 m/s
g la aceleración de la gravedad 9.81 m/s2
y t el tiempo medido en segundos
Entonces para calcular la altura después de un segundo:
y = 18 m/s x 1 seg - 1/2 9.81 m/s2 (1 seg)^2 = 18 m - 4.9 m = 13.1 m
