1. In right triangle ABC, altitude CD is drawn to hypotenuse AB. If DB = 3
and CD = 6, find AD.
Answers
Answer:
3√2
Step-by-step explanation:
Given the following;
DB = 3
CD = 6,
Required
find AD.
using the similarity property of a triangle
DB/AD = AD/CD
3/AD = AD/6
3*6 = AD²
18 = AD²
AD = √18
AD= √9*√2
AD = 3√2
Hence the measure of AD is 3√2

increases exponentially at a rate of 10% per week. Initially there are 500
ants.
a) Show that the number of ants in the colony forms a geometric progression
b) The number of ants in week 8 is p times greater than in week 6. Find the value of p.
Answers
Answer:
a) The number of ants in week three is shown through the following geometric progression: 500*1.1*1.1*1.1
b) 1.21
Step-by-step explanation:
We know that 500 ants are increasing at a rate of 10% every week which means that we can calculate the week one ants like this
500*1.1
Week two
500*1.1*1.1
and so on.
We write the following equation
500(1.1)^n where n is the number of weeks
We plug in 8 and then 6 for n in the equation above and get
500(1.1)^8=1071.79
500(1.1)^6=885.78
Divide and get that p=1.21

Write an
explicit formula for an, the nth term of the sequence 5, 15, 25, ....
Answers
Given:
The sequence is 5, 15, 25, ... .
To find:
The explicit formula for the nth term of the given sequence.
Solution:
We have,
5, 15, 25, ...
It is an AP because the difference between two consecutive terms are same.
Here,
First term : a = 5
Common difference : d = 15 - 5 = 10
Now, the explicit formula for the nth term of an AP is
[tex]a_n=a+(n-1)d[/tex]
Where, a is the first term and d is the common difference.
[tex]a_n=5+(n-1)10[/tex]
[tex]a_n=5+10n-10[/tex]
[tex]a_n=10n-5[/tex]
Therefore, the required explicit formula for the given sequence is [tex]a_n=10n-5[/tex].

ACBStep-by-step explanation:
On a position-time graph, "does not move" means the position is a constant—a horizontal line.
"Positive velocity" means the position is increasing as time increases. The graph goes up to the right. The rate of change (slope) is the velocity.
"Negative velocity" means the position is decreasing as time increases. The graph goes down to the right. Again, the rate of change (slope) is the velocity.
The various sections of the graph are identified in the attachment.
The bookstore has 4 women's magazines and 76 other magazines. What percentage of the magazines at the bookstore are women's magazines?
Answers
—
Women’s magazines = 4
Total magazines = 76
Divide no. of women’s magazines by no. of total magazines and multiply by 100
4/76 x 100 = 5.26%
This question is dealing with fractions and percentages.
Fractions and percentages are just means of expressing a part of a whole portion.
percentage of magazines that belong to women is = 5%
Number of women magazines = 4
Number of other magazines = 76
Total number of magazines = 4 + 76 = 80
Therefore,
percentage of magazines that belong to women is; [tex]\frac{4}{80}[/tex] × 100
percentage of magazines that belong to women is = 5%

Prove that the sum of the squares of two consecutive integers is odd
Answers
Answer:
Step-by-step explanation:
Start by breaking up the question into parts:'always an odd number' . An even number is any number divisible 2 e.g. 2n, an odd number is always 1 higher or lower than an even number e.g. 2n+1 or something similar. Getting an answer at the end of working of this form will prove the theory'any two consecutive integers' means two numbers that are next to each other on the number line.To prove this, we can do this in terms of n i.e. n and n+1'the squares' square the two terms we have just written down to give n2 and (n+1)2The 'sum of the squares' tells us to add these two parts together. We would then hope to work through this and get something similar to the idea of 2n+1 or something similarn2+(n+1)2=2n2+2n+1=2(n2+n) +1. The first part of this is even because it is divisible by 2. By adding 1 it must become odd.
Answer: Every even number can be expressed in the form (2n) where n is an integer. So we have an even number, 2n, and an odd number, 2m+r. Adding them together we get 2n + 2m + r, which can be expressed as 2 (n+m) + r.
A cellphone company charges you $17 a month plus $0.25 for each text message you send. The total bill last month was $45.50. Which of the following equations could you use to figure out how many text messages you sent?

17x + 0.25 = 45.50
17 - 0.25x = 45.50
17 + 0.25x = 45.50

The value of m is 7 in the equation [tex]-5m = -35.[/tex]
The given equation is [tex]-5m = -35[/tex].
In the equation, the variable is m.
To find the value of m, divide both sides by 5:
[tex]-m=-\frac{35}{5}[/tex]
[tex]-m=-7[/tex]
The minus sign on both sides will be cancelled.
[tex]m=7[/tex]
Hence, the value of m is 7 in the equation [tex]-5m = -35.[/tex]
