Answer:

Step-by-step explanation:

y = 450 × 1.18^t

:::::

450 × 1.18^t = 1,030

1.18^t = 1,030/450 = 103/45

t×ln(1.18) = ln(103/45)

t ≈ 5 hours

VOLUME A standard shipping box measures x inches high. The width is 3.5 inches more than the height, and the length is 3 inches
Allushta [10]

Answer:

62.333 inches

Step-by-step explanation:

To find the value of x, or the height of the object, we can set up an equation to solve for the missing variable. This is shown below:

x*3.5*3=561 cubic inches

To solve for X, we divide the 3.5 over to the other side, resulting in x*3 = 187

To get the x by itself, we divide both sides by 3 to remove the 3 from the left side of the equation.

We are left with x = 62.333 inches.

Therefore, the height of the box is 62.333 inches

Factor completely<br> 9-6a-24a^2
Natasha_Volkova [10]
-24a²- 6a +9 = - 3(8a² +6a - 9)

8a² +6a - 9 =0

x=(-b +/-√(b² - 4ac))/2a
x = (-6 +/-√(36+4*8*9)  /(2*8) = (-6 +/-√(324)  /16 =  (-6 +/-18)/16
x1 =  (-6 +18)/16 = 0.75
x2 =  (-6 -18)/16 = - 1.5

-24a²- 6a +9 = - 3(8a² +6a - 9) = -3(a - 0.75)(a + 1.5)
