PLEASE HELP! a. How many 7-digit numbers have odd numbers in the odd positions (i.e. odd numbers in the first, third, fifth and seventh positions)?
(2)
b. How many of these have even numbers in the even positions?
Answer:
a) 625,000
b) 78,125 if 0 is counted as even or 40,000 if it is not.
Step-by-step explanation:
Represent the 7 digit number by abcdefg
Position Allowable digits Number of allowable digits
g 1,3,5,7,9 5
f 0,1,2,3,4,5,6,7,8,9 10
e 1,3,5,7,9 5
d 0,1,2,3,4,5,6,7,8,9 10
c 1,3,5,7,9 5
b 0,1,2,3,4,5,6,7,8,9 10
a 1,3,5,7,9 5
This implies that the number of 7 digit numbers with odd digits in the odd positions is
5x10x5x10x5x10x5=625000
For part b, count 0 as an even digit. Then rule out 1,3,5,7,9 in positions b, d, and f. This leaves 5 possible digits in all 7 locations. So the answer is
5^7=78,125
If 0 is not counted as an even digit, then the answer is
4^3+5^4=40000

Step-by-step explanation:
[tex] - 3 + \sqrt{m + 59} = m \\ \sqrt{m + 59} = m + 3 \\ {(m + 59)}^{ \frac{1}{2} } = m + 3 \\ \frac{1}{2} log(m + 59) = log(m + 3) \\ 0.5 log(m) + 0.5 log(59) = log(m)+log(3) \\ 0.5 log(m) = 0.5 log(59) - log(3) \\ [/tex]
[tex]0.5 log(m) = 0.885 - 0.477 \\ 0.5 log(m) = 0.408 \\ log(m) = 0.816[/tex]

A 2-bedroom apartment that rents for $520 a month is $40 less than twice the cost of a 1-bedroom apartment. What is the monthly rent of a 1-bedroom apartment?
Answer:monthly rent of a 1-bedroom apartment= $280
Step-by-step explanation:
Let the cost of 1 bed room apartment = x
And the cost of two bedroom apartment= 2x-40
Since the cost of of two bedroom apartment = $520
Then the cost of one bed room part will be expressed as
520= 2x- 40
520+40 = 2x
560= 2x
x= 560/ 2
x= 280
Therefore the cost of 1 bed room apartment = x= $280

Brayden stated that a flying disc had a circumference of 43.96 in. Eliza wanted to find the area of the same flying disc. What is the area of the flying disc rounded to the nearest whole number? Both Brayden and Eliza used 3.14 for π.
Step-by-step explanation:
circumference(c)=43.96
2πr=43.96
r=43.96÷2π
radius ( r)=7
Now,
area(a)=πr^2

Chris works at a jewelry store, and he earns 4% commission on all sales that he makes. If Chris's jewelry sales total $1,370, how much will he earn in commission?
Answer:
[tex]\boxed {\boxed {\sf \$54.80}}[/tex]
Step-by-step explanation:
Chris earns the commission on the jewelery sales. To calculate what he earned, multiply the commission rate and his sales.
[tex]commission= commission \ rate * sales[/tex]
His rate is 4% and his sales are $1,370
[tex]commission= 4\% * \$1370[/tex]
Convert the percent to a decimal. Divide by 100 or move the decimal two spots to the left.
4/100= 0.04 4.0 --> 0.4 --> 0.04[tex]commission= 0.04* $1370[/tex]
[tex]commission = \$ 54.8[/tex]
Chris's commission is $54.80

Scott is 72 inches tall and Chris is 185 centimeters tall how tall is Chris in inches?
Answer:
Around 72.8 inches
Step-by-step explanation:
We are given the infomation that Chris is 185 centimeters tall.
There are 2.54 centimeters in an inch.
185/2.54 = 72.8346 ≈ 72.8
Chris should be around 72.8 inches.
Hope this helps.
Chris should be around 72.8 inches tall.
Here, we have,
given that,
Scott is 72 inches tall and Chris is 185 centimeters tall
We are given the information that Chris is 185 centimeters tall.
now, we know that,
There are 2.54 centimeters in an inch.
Since 1 inch = 2.54 centimeters
all we need to do is to divide 185 by 2.54
i.e. 185/2.54 = 72.8346 ≈ 72.8
The answer will be 72.8.
Chris should be around 72.8 inches.

1 - Find the values of x for which the combined function h(x) = f(x)/g(x) is undefined if f(x) = 5x + 1 and g(x) = x^2 - 9.
x = ±3
x = 3
x = -3
x = ±9
2 - Find the function h(x) = f(x) - g(x) if f(x) = 3^x and g(x) = 3^2x - 3^x.
h( x) = 0
h( x) = -3 ^2x
h( x) = 3 ^x(2 - 3 ^x)
h( x) = 2(3 ^2x)
Answer:
Part 1)
A
Part 2)
C
Step-by-step explanation:
1)
We are given:
[tex]f(x)=5x+1\text{ and } g(x)=x^2-9[/tex]
And that:
[tex]h(x)=f(x)/g(x)[/tex]
And we want to now for which values of x is h(x) undefined.
So, by substitution:
[tex]\displaystyle h(x)=\frac{5x+1}{x^2-9}[/tex]
Remember that for rational functions, the function will be undefined if and only if the denominator is 0.
This is because we cannot divide by 0.
So, to find the values for which the denominator is 0, set the denominator to 0 and solve for x. Therefore:
[tex]x^2-9=0[/tex]
Add 9 to both sides:
[tex]x^2=9[/tex]
Take the square root of both sides. Since we are taking an even-root, we will need plus/minus. Therefore:
[tex]x=\pm 3[/tex]
So, h(x) is undefined for ±3.
Our answer is A.
2)
We are given:
[tex]f(x)=3^x\text{ and } g(x)=3^{2x}-3^x[/tex]
And we want to find:
[tex]h(x)\text{ if } h(x)=f(x)-g(x)[/tex]
So:
[tex]h(x)=3^x-(3^{2x}-3^x)[/tex]
Distribute:
[tex]h(x)=3^x-3^{2x}+3^x[/tex]
Combine like terms:
[tex]h(x)=2(3^x)-3^{2x}[/tex]
Rewrite:
[tex]h(x)=2(3^x)-(3^x)(3^x)[/tex]
Factor out:
[tex]h(x)=3^x(2-3^x)[/tex]
So, our answer is C.
