Answer:
50ft
Step-by-step explanation:
Hi,
Considering that one side is equal to 38 degrees, we know this isn't a 30 - 60 - 90 triangle.
One of the legs is equal to 40 feet
So, tan(b) = 40/x
tan(38 degrees) is 0.78 round up to 0.8 (if that's what your teacher wants)
0.8 = 40/x
0.8x = 40
x = 50ft

Which answer describes the sequence {1,3,7,15,…} as a mathematical statement? The nth value equals 1 more than twice the first value. The nth value equals 1 more than twice the previous value. The nth value equals the sum of the previous 3 values. The nth value equals 1 more than the sum of the previous value and n. Checkpoint 04 Click on the numbers to jump from one question to another.
Answer:
Step-by-step explanation:
Each new value is 1 plus twice the previous value.
First value is 1. Then,
1 plus twice 1 = 3, the second value.
Second value is 3
1 plus twice 3 = 7, so
Third value is 7
and so on (this is merely a check)
An arithmetic sequence is a sequence in which the difference between any two terms of the sequence is the same or equal. The nth of the series will be aₙ =1 + (n-1)2.
What is Arithmetic Sequence?An arithmetic sequence is a sequence in which the difference between any two terms of the sequence is the same or equal.
aₙ = a₁ + (n-1)d
where,
aₙ is the nth term of the sequence,
a₁ is the first term of the sequence,
r is a common difference between every two terms.
The arithmetic sequence given is 1,3,7,15,…, therefore, the common difference between the series and the value of the first term can be written as,
d = 3-1 = 2
a₁ =1
the nth term of the series can be defined as the,
aₙ = a₁ + (n-1)d
aₙ =1 + (n-1)2
Hence, the nth of the series will be aₙ =1 + (n-1)2.

is y=x^2-4 linear or non linear
Answer:
Non linear, because x is squared. It's a bi-quadratic polynomial, not a linear polynomial.
Answer:
The polynomial y = 2x² - 4 is a bi - quadratic polynomial & hence is a non - linear polynomial.

ABCD is an isosceles trapezoid.
measure of angle b=
measure of angle d=
measure of angle c=
Answer:
∡b = 53°
∡d = 127°
∡c = 127°
Step-by-step explanation:
in trapezoids, the two top angles are equal and the two bottom are equal
also, there are 360 degrees in any 4-sided polygon
53 + 53 + x + x = 360
2x + 106 = 360
2x = 254
x = 127

Moe painted the lid of the barrel. The circumference of the barrel is 32*3.14 inches. What is the area of the lid in square inches?
Answer: 803.84 inch²
Step-by-step explanation:
The lid will take the appearance of a circle so the area of the lid is the same as the area of a circle:
Area of a circle = π * radius²
The circumference of a circle is:
= π * diameter
Looking at the above, the diameter is 32inches because this is the figure to be multiplied with π = 3.14 to find the circumference.
Since diameter is 32, radius will be:
= 32 / 2
= 16 inches
Area = 3.14 * 16 * 16
= 803.84 inch²

x
If
y

60
when
x

36
find,
x
when
y
=
80
Answer:
Step-by-step explanation:
y=k[tex]\sqrt{x}[/tex]
60=k[tex]\sqrt{36\\}[/tex] =k6
k=60/6 =10
This is your equation
y=10[tex]\sqrt{x}[/tex]
Put the numbers in
80=10[tex]\sqrt{x}[/tex]
80/10=8 then you have to square this so
[tex]8^{2}[/tex]=64
x=64

The two angles with y in them need to add up to 180 degrees
10y + 3y + 11 = 180
Simplify:
13Y + 11 = 180
Subtract 11 from both sides
13y = 169
Divide both sides by 13
Y = 13
Now solve for those two angles:
10y = 10(13) = 130
3y + 11 = 3(13) + 11 = 50
The other two angles are the same as these.
The larger angles = 130
The smaller angles = 50

Explain why a 75% discount followed by an additional 25% discount is not the
same as a 100% discount.
Answer:
Because you first take 75% off of the first price then 25% off the discounted price
Example:
Lets say you have a item that cost $50 and you use a 75% discount card that will make the item $37.5. The you add an additional 25% off which will equal $9.38.
KatyDid Clothes has a $120 million (face value) 25-year bond issue selling for 103 percent of par that carries a coupon rate of 9 percent, paid semiannually.
Answer:
8.704%
Step-by-step explanation:
The computation of the before cost of debt is as follows
Given that
Future value = $100
Present value = $103
NPER = 25 × 2 = 50
PMT = $100 × 9% ÷ 2 = $4.5
The formula is presented below:
= -RATE(NPER;PMT;PV;FV;TYPE)
After applying the above formula, the rate is 4.3518%
Yearly rate is
= 4.3518% ×2
= 8.704%

A survey found that women's heights are normally distributed with mean 63.7 . And standard deviation 3.7 . The survey also found that men's heights are normally distributed with mean 67.5. And standard deviation 3.7. Consider an executive jet that seats six with a doorway height of 56.4. Complete parts (a) through (c) below.
Complete question :
A survey found that women's heights are normally distributed with mean 63.6 in and standard deviation 3.7 in. The survey also found that men's heights are normally distributed with mean 69.3 in and standard deviation 3.7 in. Consider an executive jet that seats six with a doorway height of 55.7 in.
1-What percentage of adult men can fit through the door without bending?
2-) Does the door design with a height of 56.35in. appear to be adequate? Why didn't the engineers design a larger door? Choose answer below
A. The door design is inadequate, because every person needs to be able to get into the aircraft without bending. There is no reason why this should not be implemented.
B. The door design is adequate, because the majority of people will be able to fit without bending. Thus, a larger door is not needed.
C. The door design is inadequate, but because the jet is relatively small and seats only six people, a much higher door would require major changes in the design and cost of the jet, making a larger height not practical.
D. The door design is adequate, because although many men will not be able to fit without bending, most women will be able to fit without bending. Thus, a larger door is not needed.
Answer:
A.) 0.135%
B.) C. The door design is inadequate, but because the jet is relatively small and seats only six people, a much higher door would require major changes in the design and cost of the jet, making a larger height not practical.
C.)
Step-by-step explanation:
Percentage of adult men that can fit the door without bending :
Obtain the Zscore :
Mean height of men, m = 67.5
Standard deviation, s = 3.7
Zscore = (x - m) / s ; where x = 56.4
Zscore = (56.4 - 67.5) / 3.7
Zscore = - 11.1 / 3.7
Zscore = - 3
P(Z < - 3) = 0.0013499 (Z probability calculator)
P(Z < - 3) = 0.0013499 * 100% = 0.13499%
