Which numbers are perfect squares? Check all that apply. 02 016 018 032 0 044 094 100
Answer:
16, 100
Step-by-step explanation:
A perfect square is a number that can be achieved by multiplying a number by itself.
Example: 100 = 10 x 10, so it is a perfect square
2 is not a perfect square because it has no factors that can be multiplied with each other to equal 2. An easy way to check is to use the square root function on your calculator.
If the result is a whole number then it's a perfect square.

If y = x then dy, the differential of y, as a changes from 64 to 64.1 is given
by
Answer:
[tex]dy \ = \ 0.1[/tex]
Step-by-step explanation:
Considering the Leibniz notation to represent the derivative of [tex]y[/tex] with respect to [tex]x[/tex], suppose [tex]y \ = \ f\left(x\right)[/tex] is a differentiable function, let [tex]dx[/tex] be the independent variable such that it can be designated with any nonzero real number, and define the dependent variable [tex]dy[/tex] as
[tex]dy \ = \ f'\left(x\right) \ dx[/tex],
where [tex]dy[/tex] is the function of both [tex]x[/tex] and [tex]dx[/tex]. Hence, the terms [tex]dy[/tex] and [tex]dx[/tex] are known as differentials
Dividing both sides of the equation by [tex]dy[/tex], yield the familiar expression
[tex]\displaystyle\frac{dy}{dx} \ = \ f'\left(x\right)[/tex].
Given that [tex]f\left(x\right) \ = \ x[/tex] and [tex]dx \ = \ 64.1 \ - \ 64 \ = \ 0.1[/tex], hence
[tex]f'\left(x\right) \ = \ 1[/tex].
Subsequently,
[tex]dy \ = \ f'\left(64\right) \ \times \ 0.1 \\ \\ dy \ = \ 1 \ \times \ 0.1 \\ \\ dy \ = \ 0.1[/tex].

It says 1/2 is equal to which means 1/2 is on the side for one of the equations. It doesn't really matter. It says is equal to a number, c and eight. Its implying that you multiply c and 8 together because if it meant for another number to be multiplied then a third symbol would be in the operation.
If sin(θ)=−24/25, and θ is in Quadrant III, then what is tan(θ/2)?
Recall the Pythagorean identity,
[tex]\sin^2(\theta) + \cos^2(\theta) = 1[/tex]
Since [tex]\theta[/tex] belongs to Q3, we know both [tex]\sin(\theta)[/tex] and [tex]\cos(\theta)[/tex] are negative. Then
[tex]\cos(\theta) = -\sqrt{1 - \sin^2(\theta)} = -\dfrac7{25}[/tex]
Recall the half-angle identities for sine and cosine,
[tex]\sin^2\left(\dfrac\theta2\right) = \dfrac{1 - \cos(\theta)}2[/tex]
[tex]\cos^2\left(\dfrac\theta2\right) = \dfrac{1 + \cos(\theta)}2[/tex]
Then by definition of tangent,
[tex]\tan^2\left(\dfrac\theta2\right) = \dfrac{\sin^2\left(\frac\theta2\right)}{\cos^2\left(\frac\theta2\right)} = \dfrac{1 - \cos(\theta)}{1 + \cos(\theta)}[/tex]
[tex]\theta[/tex] belonging to Q3 means [tex]180^\circ < \theta < 270^\circ[/tex], or [tex]90^\circ < \theta < 135^\circ[/tex], so that the half-angle belongs to Q2. Then [tex]\sin\left(\frac\theta2\right)[/tex] is positive and [tex]\cos\left(\frac\theta2\right)[/tex] is negative, so [tex]\tan\left(\frac\theta2\right)[/tex] is negative.
It follows that
[tex]\tan\left(\dfrac\theta2\right) = -\sqrt{\dfrac{1 - \cos(\theta)}{1 + \cos(\theta)}} = \boxed{-\dfrac43}[/tex]

O The mean of the set is less than the median.
O The mode of the set of scores is 96.
O The median of the set of scores is 86.
o The mean and the median of the set of scores are the same.
Answer:
the mean and the median of the set of scores are the same.
Step-by-step explanation:
median = 89
mean = 96+77+86+97+89 = 445 / 5
= 89
mode = none
The mean and the median of the set of scores are the same.
What is mean and median?Introduction to Mean, Median, and Mode: In statistics, we frequently choose a representative value to roughly characterise the entire collection of data. The name "measure of central tendency" denotes that this representative value is one around which the data is centred. The mean, median, and mode are these central tendencies. The most typical way to measure central tendency is with the mean. In actuality, it represents the mean of the specified set of data. Both continuous and discrete data can be used with it. In most cases, the median shows the midpoint of the given set of data when it is arranged in a specific order.
Mean: - Average value
Median: - Middle term (after arranging in either accending or descending order)
Mean = 445/5 = 89
Median = Middle term = 3rd term = 89
Mean and median are equal.
Hence, option D is correct

Suzanne is looking at taking out a personal loan. Opportunity Loans is offering her $1600 at 3.45% for 1 year, with interest compounding monthly. General Loans is offering her $1600 at 4.2% for 1 year, with interest compounding quarterly. Assuming she makes no payments until the 1 year is up, how much interest will have accrued on each loan? On which loan will she earn the least amount of interest?
Step-by-step explanation:
So the general formula for compound interest is [tex]A = P(1+\frac{r}{n})^{nt}[/tex] where r is the interest rate, t is the time in years, and n is the amount of compounds per year. So plugging in the values for both equations you'll get
Opportunity Loans:
[tex]A = 1600(1+\frac{0.0345}{12})^{(12)(1)}[/tex]
[tex]A = 1600(1.002875)^{12}[/tex]
[tex]A \approx 1600(1.035)[/tex]
[tex]A = \$1,656.08[/tex]
Now to find the interest accrued on this loan you simply subtract 1600 from the A or final amount
[tex]Interest=1656.08-1600\\Interest=56.08[/tex]
General Loans:
[tex]A = 1600(1+\frac{0.042}{4})^{(4)(1)}[/tex]
[tex]A = 1600(1.0105)^4[/tex]
[tex]A \approx 1600(1.042)[/tex]
[tex]A = 1,668.27[/tex]
To find the interest we do the same thing we did in the previous problem
[tex]interest = 1668.27-1600\\interest=68.27[/tex]
Opportunity loans has the least amount of interest after a year

Step-by-step explanation:

the travel paths of the plane build a right-angled triangle.
one travels north, which creates the vertical leg.
the other travels west, which creates the horizontal leg.
their distance is the Hypotenuse (the baseline opposite of the 90° angle), which we can get via Pythagoras
c² = a² + b²
c being the Hypotenuse, a and b being the legs.
how long are the legs ?
the plane going north travels at 240 km/h for 90 minutes.
the plane going west travels at 180 lm/h for 90 minutes.
90 minutes = 1.5 hours (1 hour 30 minutes).
so,
plane 1 went 240×1.5 = 360 km.
plane 2 went 180×1.5 = 270 km.
distance² = 360² + 270² = 129600 + 72900 = 202500
distance = sqrt(202500) = 450 km
2A
again Pythagoras :
130² = 80² + (2nd leg)²
16900 = 6400 + (2nd leg)²
10500 = (2nd leg)²
2nd leg = 102.4695077... m
so, the full perimeter is
130 + 80 + 102.4695077... = 312.4695077... m
312.4695077... = 100%
1% = 100%/100 = 3.124695077... m
how many % are 220 m ? well as many as how often 1% fits into 220 m :
220 / 3.124695077... = 70.40686998... %
3A
again Pythagoras :
the legs of that inner right-angled triangle are (as you correctly wrote) 40 m and 45 m.
the fence is the Hypotenuse, and we get
fence² = 40² + 45² = 1600 + 2025 = 3625
fence = 60.20797289... m ≈ 60 m
please burn that into your brain forever for any right-angled triangle situations :

You can somewhat think of this situation as a sort of tree.

Each one of those has 5 sticks for the ties, which in turn each have 6 leaves to represent the jackets and therefore a complete outfit. The solution is found by getting the total number of leaves on the tree.

6) You have a rectangular backyard that is 90 feet wide. It has an area of 10,800 square feet. You are
putting a fence along one length of the yard.
a. Use the formula for the area of a rectangle A = 1 w, where I is the length, and w is the width. Find
the length of your backyard.
b. The fence costs $12.50 per linear foot. What is the total cost of the fence for one length of the yard?
Answer:
Length = 120 ft
Total cost = 1500$
Step-by-step explanation:
First, to find the length of the backyard we reverse the formula (A = l * w) and divide 10,800 by 90.
10,800 ft^2 / 90 ft = 120 ft.
we can check this by plugging the length of 120 ft into the formula:
120 ft * 90 ft = 10,800 ft^2.
Next, to find the cost of the single length of fence we multiply our length (120 ft) by the cost ($12.50):
120 * 12.50 = $1500
A disk is in the form of square and measures 5.25 inches on each side. Find
the diagonal length of the disk?
Answer:
The diagonal length of the desk is 7.42462120246 inches.
Step-by-step explanation:
Since it is a square then all sides are equal which means we can easily formulate the pythagorean theorem on the diagonal length of the desk.
a^2 + b^2 = c^2
A and B are the same (width and length) since it is a square.
5.25^2 + 5.25^2 = c^2
27.5625 + 27.5625 = c^2
55.125 = c^2
Put c^2 under a square root (apply to both sides)
square root of 55.125 = 7.42462120246 = c
