Finding the tangent of angle E
Answer:
tan(E) =[tex]\sqrt{3\\}[/tex]
Step-by-step explanation:
Given: ED = 4[tex]\sqrt{6}[/tex] and CD = 6[tex]\sqrt{2\\}[/tex]
Step 1 : Find CE
ED² = CE² + CD²
(4√6)² = (CE)² + (6√2)²
96 = CE² + 72
24 = CE²
CE = 2√6
Step 2 : Find ∠E using side lengths
Based on our leg lengths : 6√2 & 2√6 , we can conclude that this is a
30-60-90 triangle (the sqaures are opposites yk)
Because 6√2 is the larger leg, and ∠E is opp side of CD,
∠E = 60
From there all you do is find the tangent with a calculator "tan(60)"
What is the Mean of the data set? 12, 15, 18, 23, 26
Answer:
Mean = 18.8
Step-by-step explanation:
Mean = (Sum of all values)/(Number of values)
Mean = (12 + 15 + 18 + 23 + 26)/5
Mean = 94/5
Mean = 18.8
Answer:
18.8
Step-by-step explanation:
12+15+18+23+26=94 94/5 (5 is how many pair of numbers there are)=18.8

b. Find the order of magnitude of the volume V of Europa.
c. Use the orders of magnitude of mand V that you found in parts (a) and
(b) to approximate the average density d (in kilograms per cubic meter)
of Europa using the formula d = m.
Answer:
Given
r = 1 600 000 m = 1.6×10⁶ mm = 48 000 000 000 000 000 000 000 kg = 4.8×10²² kga)

Answer:
-1 7/8, -1 1/2, -1 1/4, -1
Step-by-step explanation:
First note that the negative value closer to zero on the number is greater. an those far from zero will be the least
According to the given option, we can first express the fractions as percentage as shown
-1 7/8 = -15/8 * 100 = -187.5%
-1 1/2 = -3/2 * 100 = -150%
-1 1/4 = -5/4 * 100 = -125%
-1 = -1 * 100 = -100%
Based on the explanation above, the least value is -187.5% and the greatest value is -100%
Rearranging from least to greatest is expressed as -187.5%,-150%, -125%, -100%
According to their respective fractions;
-1 7/8, -1 1/2, -1 1/4, -1

Answer:
A Kite Ahe guessedStep-by-step explanation:
For a quadrilateral in which the diagonals cross at right angles, such as a rhombus or kite, the area can be found as half the product of the diagonals.
For the purpose here, we can ignore the factor of 1/2, which is the same for both, and simply consider the products of the diagonals.
Kite A has an area proportional to (30 in)(30 in) = 900 in².
Kite B has an area proportional to (20 in)(40 in) = 800 in².
Kite A has a larger area, so will use more paper.
__
Only Rudy knows why he chose answer C. Perhaps he guessed, rather than doing any math.
Answer:
A. Kite A
Step-by-step explanation:
To determine which of the two kites will use need more paper to make, find the area of each kite.
Kite A:
Area = (d1*d2)/2
d1 = 30 in.
d2 = 30 in.
Area of kite A = (30*30)/2 = 450 in.²
Kite B:
Area = (d1*d2)/2
d1 = 20 in.
d2 = 40 in.
Area of kite B = (20*40)/2 = 400 in.²
✅Kite A will use more paper to make because it has a greater area of 450 in.² than Kite B (400 in.²).
So, Ruby was wrong. He most likely didn't calculate the area of both kites correctly.

How much must be deposited today into the following account in order to have get 35,000 in 5 Years
An account with monthly compounding and an APR of 4%
should be deposited today.
(Do not round until the final answer. Then round to the nearest cent as needed)
Answer:
$ 28,665.11 must be deposited today into the account.
Step-by-step explanation:
Given that there is an account with monthly compounding and an APR of 4%, to determine how much must be deposited today into the following account in order to have $ 35,000 in 5 years, the following calculation must be performed:
X x (1 + 4/12) ^ 5x12 = 35,000
X x (1 + 0.333) ^ 60 = 35,000
X x (1,333) ^ 60 = 35,000
X x 1.220999 = 35,000
X = 35,000 / 1.22099
X = 28,665.11
Thus, $ 28,665.11 must be deposited today into the account.

Write the recursive form equation given the explicit
an=5(2)n−1
ANSWER CHOICES:
an=an−1⋅ 2an=an−1⋅ 2
an=an−1+2A sub n is equal to A sub n minus 1 plus 2
an=an−1+5A sub n is equal to A sub n minus 1 plus 5
an=an−1⋅ 5
Answer:
In recursive form, we could write a(n + 1) = 2a(n) with a(1) = 5.
Step-by-step explanation:
If you meant a(n) = 5(2)^(n - 1), then you have a geometric series with first term 5 and common ratio 2. Each new term is 2 times larger than the previous term.
In recursive form, we could write a(n + 1) = 2a(n) with a(1) = 5.
Example: If a(1) = 5, the next term, a(1 + 1), or a(2), is 5*2, or 10.

What is the slope of the line that passes through (1, 4) and (1, −3)? (1 point)
Answer:
undefined
Step-by-step explanation:
[tex]\boxed{slope = \frac{y1 - y2}{x1 - x2} }[/tex]
Slope of the line
[tex] = \frac{4 - ( - 3)}{1 - 1} [/tex]
[tex] = \frac{7}{0} [/tex]
(undefined)
Notice that the two points have the same x-coordinate of 1. This means that the line is a vertical line, and vertical lines have undefined slopes.
Answer:
Undefined slope
Step-by-step explanation:
(1, 4) and (1, −3)
Slope:
m=(y2-y1)/(x2-x1)
m=(-3-4)/(1-1)
m=(-7)/0
When 0 is the denominator, there's no slope since it's undefined.
Undefined slope

The graph of a function f is shown below.
Find f(0).
Answer: f(0)=-1
Step-by-step explanation:
f(0) is a fancy way of saying the y value of the equation. the f(0) means that x=0. If you look at x=0, the graph is at y=-1. Therefore, f(0)=-1.
Answer:
7, f(0) would have to be lower than the semi-circle shown below, and therefore because the line passes through -3 and -4, its |-7|, which is 7.
