Abel and Zöe’s grandparents opened a savings account for an equal amount upon the birth of each child. Now, the values of their

accounts could be found by the following expressions, where t represents the years since 2011. Abel: y = 1266. 77(1. 03)t Zöe: y = 1159. 27(1. 03)t Based upon this information, find the difference in the children’s ages. Abel is years older than Zöe. Suggestions: Find the ratio 1266. 77/1159. 26. What does that ratio represent in terms of powers of 1. 03? You also can graph both equations and figure out the shift.

Answer:

Abel is 3 years older than Zoe.

Step-by-step explanation:

Abel: y = 1266.77(1.03)^t

Zöe: y = 1159.27(1.03)^t

To find the difference in children's ages first we take ratio of 1266.77/1159.26

Ratio of 1266.77/1159.26= 1.09

now when you write ratio in terms of powers of 1.03

1.03^t = 1.09

Take ln on both sides

t ln(1.03) = ln(1.09)

Then you divide both sides by ln(1.03)

t= 3

Abel is 3 years older than Zöe.

Which graph shows y=1/2⌈x⌉?
12345 [234]

The correct answer is option B which is the graph that represents the equation y = (1/2)x will be the second option in the figure. At every value of y, the value of x is double.

<h3>What is a graph?</h3>

A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.

The graph of the equation y =1/2x is represented in the answer below we can see in the graph that at every value of y the value of x is double for example if we put y = 1 then the value of x will be 2.

y = 1/2 x

at x = 2

y = 1/2 x 2

x = 1

Therefore the correct answer is option B which is the graph that represents the equation y = (1/2)x will be the second option in the figure. At every value of y, the value of x is double.

Find ????⋅ ???? if |????|=3 , |????|=9 , and the angle between ???? and ???? is π2 radians.
mrs_skeptik [129]

Answer:

a{\cdot}b=0

Step-by-step explanation:

It is given that,

Magnitude of a A, |A|=3

magnitude of B, |B|=9

The angle betwern a and b is \dfrac{\pi}{2}\ rad=90^{\circ}

Dot product,

a{\cdot} b=|a||b|\ \cos\theta\\\\a{\cdot} b=3\times 9\times \ \cos(90)\\\\a{\cdot} b=0

So, a.b is equal to 0.

What is the slope-intercept equation for the following line?
natita [175]

Answer:

Minus 3 (-3), not +

Step-by-step explanation:

The slope intercept or y-intercept is where the line starts from the center. Since a point on the line starts at 0,-3, you pull the y out from the coordinate, because that is your answer. The line starts at -3.

If this is confusing, feel free to ask me to explain further.
