To solve an equation with a square yo would take the square root of both sides.
(4x - 5)^2 = 49
sqrt((4x - 5)^2) = sqrt49
4x - 5 = + - 7
4x - 5 = 7 and 4x - 5 = -7
4x = 12 4x = -2
x = 3 x = -1/2

Which number is an irrational number? (1 point)

NemiM [27]

Answer: The answer is (B). 1.01257486...

Step-by-step explanation: We are given four real numbers out of which we are to select the one which is irrational.

Option (A) is 0.12, in which the digits after the decimal are terminating. So, the number is rational.

Option (B) is 1.01257486..., the digits after the decimal are non-terminating and non-recurring. So, the number is irrational.

Option (C) is 0.1212121212..., in which the digits after the decimal are non-terminating and recurring. So, the number is rational.

Option (D) is 0.11111111..., in which the digits after the decimal are non-terminating and repeating. So, the number is rational.

Thus, (B) is the correct option.

Suppose a baseball is thrown vertically upward from the ground with an initial velocity of Subscript[v, 0] ft/s. Its height abov

Zina [86]

Answer:

90.5

Step-by-step explanation:

Velocity is a time-derivative of displacement or the height, in this case.

$s(t)=-16t^2+v_0t$

$v(t) = -32t+v_0$

At maximum height, the velocity is 0 and the height is 128.

Substitute these values into both equations above,

$0 = -32t+v_0$

$t=\dfrac{v_0}{32}$

From the first equation,

$128 = -16t^2 + v_0t$

Substitute for $t$ .

$128 = -16(\dfrac{v_0}{32})^2 + v_0\times\dfrac{v_0}{32}$

$128 = -v_0^2/64 + v_0^2/32$

$128=\dfrac{v_0^2}{64}$

$v_0^2=8192$

$v_0=64\sqrt{2}=90.5$
