Answer:
4.58258
Step-by-step explanation:
Pythagorean Theorem:
a² + b² = c²
Input:
2² + x² = 5²
Remember, c² is always the side opposite of the right angle...
4 + x² = 25
21 = x²
x = 4.58258

Answer:
[tex]\sqrt{21}[/tex]
Step-by-step explanation:
let the missing side be x , then
Using Pythagoras' identity in the right triangle.
x² + 2² = 5²
x² + 4 = 25 ( subtract 4 from both sides )
x² = 21 ( take the square root of both sides )
x = [tex]\sqrt{21}[/tex] ≈ 4.6 ( to 1 dec. place )

Answer:
A = 26.6°
Step-by-step explanation:
To obtain the measure of angle A :
We use the trigonometric relation :
Tan A = opposite / Adjacent
Tan A = 6 / 12
Tan A = 1/2
A = tan^-1(1/2)
A = 26.565°
A = 26.6°

Becky created a graph to represent her distance away from home one afternoon. She left home and ran to the park, met some friends and stayed at the park, and then walked back home using the same route. Which graph could Becky have created?
Answers
Answer:
probably linear graph 'cause it's in a straight line
Answer:
Step-by-step explanation:
First graph is correct which satisfies the given informations.
The graph is attached below.
Given:
Becky made a graph to show how far she was from her house.
She started jogging from zero distance from the house when she left and sprinted to the park, so the second and fourth graphs are incorrect.
She then spent some time at the park with some friends before returning home on the same path. The first one is accurate since we can see that for a brief while, the graph is parallel to the time axis, but the third one demonstrates that she hasn't taken a break.

The sine of 30 degrees is 1/2. What is the cosine of 60 degrees?
Answers
Answer:
Sine (30°) = cosine(90-30) = cos(60°) = 1/2
Step-by-step explanation:
The value of the [tex]cos 60^0[/tex] is [tex]\dfrac{1}{2}[/tex].
Recall the relationship between the sine and cosine[tex]cos^2\theta= 1-sin^2\theta\\cos 2\theta = cos^2\theta - sin^2\theta[/tex]
How to find the cosine values?Given the value of [tex]sin30^0[/tex] is [tex]\dfrac{1}{2}[/tex].
Use the relation between the sine and cosine as-
[tex]\cos^230^0=1-\sin^230^0\\=1-\dfrac{1}{4}\\=\dfrac{3}{4}\\[/tex]
Use another relation [tex]\cos 2\theta = \cos^2\theta -\sin^2\theta[/tex] as-
[tex]\cos(2\times 30^0)=\cos^2{30^0}-\sin^2{30^0}\\=\dfrac{3}{4}-\dfrac{1}{4}\\=\dfrac{1}{2}[/tex]
Hence, [tex]\cos 60^0[/tex] is value is [tex]\dfrac{1}{2}[/tex].

You buy items costing $1900 and finance the cost with a fixed installment loan for 24 months at 8% simple interest per year.
1. What is the finance charge?
2. What is your monthly payment?
* Please explain how you got the answer*
Answers
9514 1404 393
Answer:
$304$91.83Step-by-step explanation:
1. The finance charge is found from the simple interest formula;
I = Prt
where P is the principal amount, r is the annual rate, and t is the number of years.
24 months is 2 years, so the interest charged is ...
I = $1900×0.08×2 = $304
The finance charge is $304.
__
2. The monthly payment will be the total amount due, divided by the number of months.
payment = ($1900 +304)/24 = $2204/24 ≈ $91.83
The monthly payment is $91.83.

Suppose one relatively large value is added to a set of all relatively small data values. Which of the following measures would not be affected (i.e. 10 12 16 12 150 13 - which average technique would not be impacted by the outlier)?
A. the mode.
B. the standard deviation.
C. the range.
D. the mean.
Answers
Answer:
A. the mode.
Step-by-step explanation:
Mean
Sum of all values divided by the number of values, so is affected by an outlier present in the data-set.
Standard deviation:
Square root of the sum of the differences squared between each value and the mean, divided by the sample size. As it's related to the mean, it is affected by an outlier.
Range:
Subtraction of the largest value of the data-set by the smallest value, and thus, is also affected by an outlier.
Mode
Value that appears the most often in the data-set, and thus, not affected by an outlier, which means that the correct answer is given by option A.

x=3/2y+3 is the solution of the equation 2x-3y=6.
The given equation is 2x-3y=6
We need to solve for variable x in the equation.
Isolate the term with variable x.
Add 3y on both sides of the equation.
2x=6+3y
Now divide both sides by 2

if gh¢400.00 is deposited at a bank at 10% per annum compounded quarterly, how long will it take the deposit to double it value.
Answers
9514 1404 393
Answer:
7 years
Step-by-step explanation:
The multiplier each quarter is 1 +10%/4 = 1.025. The number of quarters, n, that must pass before the value is multiplied by 2 is given by ...
1.025^n = 2
Taking logarithms, we can solve for n:
n×log(1.025) = log(2)
n = log(2)/log(1.025) ≈ 28.071
It will take 28 quarters, or 7 years, for the value to double.

n = 106
Step-by-step explanation:
Given
p = 0.5 and 1-p = q = 0.5
Margin of error = 0.08
Confidence level = 90%
Z score for 90% confidence level = 1.65
As we know -
Margin of error = z * Sqrt (pq/n)
Substituting the given value, we get –
0.08 = 1.65 * Sqrt (0.5*0.5/n)
Squaring both the sides and solving, we get
n = 1.65^2*0.5^2/0.08^2
n = 106.34 = 106
