Answer:

B. 733 customers

Step-by-step explanation:

15+30+45=90

since 30 people select a black frame, 1/3 of the customers picked black frames. If this data is consistent through the month (which we have to assume it is) then that means 1/3 of customers select a black frame on average. 1/3 of 2,200 is about 733, so we can assume, using the data given, that about 733 customers selected black frames! :)

Determine whether the function shown in the graph is even or odd.

erica [24]

Answer:

Option A) The function is even because it is symmetric with respect to the y-axis.

Step-by-step explanation:

We are given a graph of the function.

We can see that the given function is symmetric around the y axis as the y axis acts as a mirror.

Symmetry around y-axis

The y-axis acts as the line of symmetry for the given graph.

A graph is said to be symmetric about the y axis if (a,b) is on the graph, then we can find the point (-a,b) on the graph as well.

Even Function:

A function is said to be even if

$f(x) = f(-x)$

A function f is even if the graph of f is symmetric with respect to the y-axis

Odd function:

A function is said to be odd if

$-f(x) = f(-x)$

A function f is even if the graph of f is symmetric with respect to the x-axis.

Thus, we can write that the given function is an even function as the the graph is symmetric to the y-axis.

Option A) The function is even because it is symmetric with respect to the y-axis.

Jacob is unsure how long it will take to save $50,000. He knows that he'll make an initial investment of $5,000, and he can earn

maksim [4K]

Answer:

It will take Jacob 36 years to reach his goal

Step-by-step explanation:

In this question, Jacob is intending to save $50,000 but he is doing this by saving $5,000 at an interest which is compounded two times a year (semi-annually). We are tasked with calculating the number of years it will take him.

Mathematically, to solve this, what we use is the compound interest formula.

This is;

A = P(1 + r/n)^nt

Where in the question A is our savings target of $50,000

P is our initial amount saved of $5,000

r is the rate at 6.5%

n is the number of times interest will be compounded per year= 2

and t is the number of years it will take.

We plug all these values respectively to yield;

50,000 = 5,000(1 + 0.065/2)^(2t)

Divide through by 5,000

we have;

10 = (1.0325)^2t

Take the logarithm of both sides

Log 10 = Log (1.0325)^2t

Log 10 = 2tLog (1.0325)

2t = Log10/Log1.0325

2t = 72

t = 72/2

t = 36 years
