Find the length of the third side. If necessary, write in simplest radical form
HERE,
the [tex]\huge{\triangle}[/tex]is a right angle traingle.
length of one side=[tex]\bold{ 1 }[/tex]
length of another side =[tex]\bold{\sqrt{3} }[/tex]
so,
the length of third side=
[tex]\bold{\sqrt{(1)^{2} +({\sqrt{3}})^{2}} }[/tex] [tex]\bold{\sqrt{1+3} }[/tex] [tex]\bold{\sqrt{4} }[/tex] [tex]{\huge{\fcolorbox{aqua}{navy}{\fcolorbox{yellow}{blue}{\bf{\color{yellow}{2}}}}}}[/tex][tex]\therefore[/tex],the length third side of the traingle is 2.

A website administrator is considering using one of the two models above to predict the total number of purchases, P, made x weeks after the website's advertisin(g campaign begins. How many more purchases are predicted by the exponential model than by the linear model 5 weeks after the advertising campaign begins?
P = 2000x
P= 500(2^x)
A. 6000
B. 8000
C. 10,000
D. 16,000
9514 1404 393
Answer:
A. 6000
Step-by-step explanation:
Use x=5 and evaluate each model.
Linear model
P = 2000(5) = 10,000
Exponential model
P = 500(2^5) = 500(32) = 16,000
The difference in the predicted value is ...
16,000 -10,000 = 6,000 . . . more are predicted by the exponential model

Alicia sews costumesfor a school play.She takes an average of 86 minutes to sew each costume.How long would she take to sew 16 of these costumes
Answer:
1376 minutes
Step-by-step explanation:
Alicia sews costumes for schools
She takes 86 minutes to sew one costume
Therefore the time taken to sew 16 costumes can be calculated as follows
86 mins= 1 costume
x= 16 costume
Cross multiply
x= 86×16
= 1376 minutes
How many solutions will the equation have?
|x- 13| - 5= -5
Answer: x=13
Step-by-step explanation: Hope this help :D
Answer:
One Solution
__________
x = 13
__________
Explanation:
| x – 13 | – 5 = -5
[Add 5 to both sides to isolate | x – 13 | and cancel out –5]
| x – 13 | – 5 + 5 = -5 + 5
[Reduce]
| x – 13 | = 0
[An absolute value can include both a positive and negative value so |x| = n → x = ±n ]
x – 13 = ± 0
[Add 13 to both sides to get the value of x]
x – 13 + 13 = 13 ± 0
x = 13 ± 0
[Adding or subtracting zero will leave you with the same number]
x = 13
Please can you help me .and give me the answer

Auntie Sammy buys a hand bag. There was a discount
of 20%.
If Auntie Sammy paid $245, what was the original price?
Answer:
Step-by-step explanation:
I think the original proce would be $265
1. Subtract the percentage discount from 100
100 - 20= 80
2. Multiply the final price($245) by 100
245 × 100= 24,500
3. Divide the answer in step 2 by the answer in Step 1
24,500 ÷ 80= $306.25
answer is $306.25
How to check to ensure your answer is correct:
1. Multiply the "answer" by the discount price divided by 100. This will give the discount percentage in dollars.
$306.25 × 0.2( which is 20÷100)= $61.25(discount in dollars)
2. Subtract the discount in dollars from the "answer"
$306.25 - $61.25= $245(final price is the same as in the problem so it is correct)
OR
1. Multiply the original price by the number you get from step 1 in your problem divided by 100
$306.25 × 0.8(80 from the very first step divided by 100)= $245(the final price is the same given in the question)

Dolores deposited $2500 into a savings account which interest compounded monthly at a rate of 2.12%
How much interest will they earn after 8 years? Round to the nearest dollar
Help pleaseeeeeeeeeee
Answer:
2961.63
Step-by-step explanation:
First, convert R as a percent to r as a decimal
r = R/100
r = 2.12/100
r = 0.0212 rate per year,
Then solve the equation for A
A = P(1 + r/n)nt
A = 2,500.00(1 + 0.0212/12)(12)(8)
A = 2,500.00(1 + 0.001766667)(96)
A = $2,961.63
Summary:
The total amount accrued, principal plus interest, with compound interest on a principal of $2,500.00 at a rate of 2.12% per year compounded 12 times per year over 8 years is $2,961.63.
Answer:

Answer:
-368.8 ft
Step-by-step explanation:
distance = velocity × time
Here, we'll use a negative for speed downward, and positive for speed upward.
elevation = (-4.5 ft/s)(98 s) +(1.9 ft/s)(38 s) = -441 ft +72.2 ft
elevation = -368.8 ft

If cos A= 1/8 With A in QIV, find sec A/2
Show work
Recall the half-angle identity,
cos²(x/2) = (1 + cos(x))/2
The angle A terminates in the fourth quadrant, so 270° < A < 360°. Then the corresponding half-angle terminates in the second quadrant, since 135° < A/2 < 180°, so cos(A/2) < 0. This means
cos(A/2) = - √((1 + cos(A))/2) = -3/4
so that
sec(A/2) = 1/cos(A/2) = -4/3.

The half-life of Palladium-100 is 4 days. After 12 days a sample of Palladium-100 has been reduced to a mass of 7 mg.
Answer:
I think this is correct but im not sure..
Step-by-step explanation:
12 days is 3 half-lives ... so, 1/8 initial ... (1/2)^3 = 1/8
... initial is 8 mg
4 weeks is 7 half-lives ... 8 mg * (1/2)^7 = ?
Answer:
56 mgStep-by-step explanation:
Let the initial mass of sample is x mgWe have the following equation:
x* [tex](\frac{1}{2}) ^{12/4}[/tex]= 7x*[tex](\frac{1}{2}) ^{3}[/tex] = 7x*[tex](\frac{1}{8} )[/tex] = 7x = 7*8x = 56 mgMalia and her sister walk at a constant rate of 4 miles per hour. At this constant rate, how long should it take Malia and her sister to walk 3 miles?

1. Becky needs to earn an average of 85% on her Stats tests in order to maintain her current GPA. IF
she has gotten the following scores so far, what does she need to get on her next test to maintain at
least an 85% average?
85, 78, 92, 84, 93
Answer:
78%
Step-by-step explanation:
85 × 6 = 510
85 + 78 + 92 + 84 + 93 = 432
510 - 432 = 78
Check
85 + 78 + 92 + 84 + 93 + 78 = 510
510 ÷ 6 = 85
