Answer:
No, the sum of the two smaller sides must be greater than the longer side.
In this case this would be just a straight line.
[tex]\huge{\textbf{\textsf{{\color{pink}{An}}{\red{sw}}{\orange{er}} {\color{yellow}{:}}}}}[/tex]
The given lengths won't form a triangle. The sum of the 2 smaller sides should be greater (not equal too) than the longest side.
so, the longest side her is 12ft
so the smaller sides are 4ft, and 8ft.
the sum of this two sides is 12ft which same as longest side (not greater)...
so it won't form a triangle, here it will just form points on lines.
thankshope it helpsYou have been commissioned to design a monument to Mr. Mullen. The monument consists of a pool 100 ft long where observers stand on one side of the pool and a giant statue of Mr. Mullen holding a cat stands on the other. If you want the angle of elevation from the ground to be 42 degrees, how tall must you make the statue?
a. 100 ft
b. 90 ft.
c. 111 ft
d. 67 ft
e. 74 ft
9514 1404 393
Answer:
b. 90 ft
Step-by-step explanation:
The opposite and adjacent sides of the relevant triangle are given.
Tan = Opposite/Adjacent
tan(42°) = h/(100 ft)
h = (100 ft)tan(42°) ≈ 90.04 ft
The statue must be about 90 ft tall.
Answer:
a. 100 ft
b. 90 ft.
c. 111 ft
d. 67 ft
e. 74 ft
its b.90 ft.
The time needed to complete a final examination in a particular college course is normally distributed with a mean of 79 minutes and a standard deviation of 8 minutes. Answer the following questions.
Answer:
A) 0.0088
B) 0.2997
C) 5
Step-by-step explanation:
Given: Mean: Ч = 79 minutes
Standard deviation : б = 8 minutes
The formula for z score:
z= x-ц/σ
a) For x=60 minutes
z= 60-79/8 = -2.375
The p-value = P(z< -2.375) = 0.0087745 ≈ 0.0088
b) For x= 75 minutes
z= 75-79/8 = -0.5
The p-value = P(60 < x < 75) = P (-2.375 < z < -0.5)
= P(-0.5)-P(-2.375)= 0.3085 -0.0088 =0.2997
c) For x=90 minutes
z= 90-79/8 = 1.375
The p-value = P (z > 1.375)= 1-P(z < 1.375)
= 1-0.9154342 = 0.0845658
If the number of students in the class=60.
Then, the number of students will be unable to complete the exam in the alotted time = 0.0845658 x 60 = 5.073948 ≈ 5
Find the average value of a function
Answer:
The average value of g is:
[tex]\displaystyle g_{ave}=\frac{1}{6}e^6-\frac{49}{6}\approx 59.071[/tex]
Step-by-step explanation:
The average value of a function is given by the formula:
[tex]\displaystyle f_{ave}=\frac{1}{b-a}\int_a^b f(x)\, dx[/tex]
We want to find the average value of the function:
[tex]g(x)=e^{3x-3}-4x[/tex]
On the interval [1, 3].
So, the average value will be given by:
[tex]g_{ave}=\displaystyle \frac{1}{3-1}\int_1^3 e^{3x-3}-4x\, dx[/tex]
Simplify. We will also split the integral:
[tex]\displaystyle g_{ave}=\frac{1}{2}\left(\int_1^3e^{3x-3}\, dx-\int _1^3 4x\, dx\right)[/tex]
We can use u-substitution for the first integral. Letting u = 3x - 3, we acquire:
[tex]\displaystyle u=3x-3\Rightarrow du = 3\, dx\Rightarrow \frac{1}{3} du=dx[/tex]
We will also change the limits of integration for our first integral. So:
[tex]u(1)=3(1)-3=0\text{ and } u(3)=3(3)-3=6[/tex]
Thus:
[tex]\displaystyle g_{ave}=\frac{1}{2}\left(\frac{1}{3}\int_0^6 e^{u}\, du-\int _1^3 4x\, dx\right)[/tex]
Integrate:
[tex]g_{ave}=\displaystyle \frac{1}{2}\left(\frac{1}{3}e^u\Big|_0^6-2x^2\Big|_1^3\right)[/tex]
Evaluate. So, the average value of g on the interval [1, 3] is:
[tex]\displaystyle g_{ave}=\frac{1}{2}\left(\frac{1}{3}\left[e^6-e^0\right]-\left[2(3)^2-2(1)^2\right]\right)[/tex]
Evaluate:
[tex]\displaystyle\begin{aligned} g_{ave}&=\frac{1}{2}\left(\frac{1}{3}(e^6-1)-16\right)\\&=\frac{1}{2}\left(\frac{1}{3}e^6-\frac{1}{3}-16\right)\\&=\frac{1}{6}e^6-\frac{49}{6}\approx59.071\end{aligned}[/tex]

What is the answer for this using substitution?
9514 1404 393
Answer:
(x, y) = (2, -2)
Step-by-step explanation:
We would normally choose to use substitution when x or y could be easily solved-for without having fractions involved. That is not the case here. However, we observe that the term 3y appears in both equations, so we can substitute for "3y" instead of "y".
From the second equation, ...
3y = 5x -16
Substituting into the first equation, ...
2x +(5x -16) = -2
7x = 14 . . . . . . . . . add 16
x = 2 . . . . . . . . . . divide by 7
Using our equation for y, we get ...
3y = 5(2) -16 = -6
y = -2 . . . . . . . . . divide by 3
The solution is (x, y) = (2, -2).
For large parties, a restaurant charges a reservation fee of $30, plus $20 per person. The total charge for a party of x people is f(x) = 20x + 30. How will the graph of this function change if the reservation fee is raised to $65 and the per-person charge is lowered to $12?
In the formula, l = a + (n - 1)d make d as the subject. Find d when l = 10, a = 2, n = 5.
I = a + (n - 1)d [Given formula]
To Find:-Find d when I = 10, a = 2, n = 5
Solution:-I = a + (n - 1)d [Given]
Putting the value of I = 10, a = 2, n = 5 we get,
10 = 2 + (5 - 1)d
10 = 2 + 4d
10 - 2 = 4d

What is the value for x that makes the equation true?
Answer:
y=10.4
Step-by-step explanation:
If you mean Y instead of x then the answer is 10.4
3.8+y=14.2
-3.8 -3.8
y=10.4
Answer:
y/x=10.4
Step-by-step explanation:
3.8+y=14.2 Subtract 3.8 from both sides
y=10.4
Is it possible for a cross section of a cylinder to have a triangular shape?
It is not possible for a cross section of a cylinder to have a triangular shape
What is cross section?Cross section is the non-empty intersection of a solid body in three-dimensional space with a plane, or the analog in higher-dimensional spaces
What is Cylinder?A cylinder has traditionally been a three-dimensional solid, one of the most basic of curvilinear geometric shapes
What is triangular shape?A triangle is a shape formed when three straight lines meet
Cross section of the cylinder is depends on how we cut .The cross-section of a cylinder may be either circle, rectangle, or oval
Hence, the cross section of of a cylinder can not be a triangular shape

Answer:
the monthly payment is $636.02
Step-by-step explanation:
The calculation of the monthly amount deposited i.e. PMT is shown below:
GIven data
NPER = 15 × 12 months = 180
RATE = 5% ÷ 12 = 0.4167%
PV = $0
FV = $170,000
based on the above information
The formula is given below:

Convert 210° to radian measure in terms of pi
Answer:
[tex]210^\circ = \frac{7}{6}\pi[/tex]
Step-by-step explanation:
Given
[tex]\theta = 210^\circ[/tex]
Required
Convert to radians
To convert to radians, we make use of:
[tex]Radians = \theta * \frac{\pi}{180^\circ}[/tex]
Substitute: [tex]\theta = 210^\circ[/tex]
[tex]Radians = 210^\circ* \frac{\pi}{180^\circ}[/tex]
[tex]Radians = \frac{210^\circ* \pi}{180^\circ}[/tex]
Simplify fraction
[tex]Radians = \frac{7\pi}{6}[/tex]
[tex]Radians = \frac{7}{6}\pi[/tex]
Hence:
[tex]210^\circ = \frac{7}{6}\pi[/tex]
the lengths of two sides of a triangle are 8in. and 13in. find the range of possible lengths for the third side
Answer:
5<x<21
Step-by-step explanation:
when any two sides are added together they have to be greater than either side... to find the range
add the two sides together to get the upper end of the range 8+13=21
and to get the lower end of the range subtract 13-8=5
so the range is 5<x<21
the third side CAN NOT be 5 or 21, must be between them

Answer:
y = [tex]-2^x[/tex]
Step-by-step explanation:
If the equation of a function is in the form of y = h(x)
When the graph of this function is reflected across x-axis,
Transformed function will be,
y = -h(x)
Further reflected across y-axis, then the transformed function will be,
y = -h(-x)
By this rule,
Given equation when reflected across x-axis,
y = [tex]-(\frac{1}{2})^{x}[/tex]
Further reflected across y-axis,
y = [tex]-(\frac{1}{2})^{-x}[/tex]
y = [tex]-(2^{-1})^x[/tex]

Suppose a certain person's reaction time, in seconds, for pressing a button on a visual cue has the following cumulative distribution function: F (x )equals 1 minus fraction numerator 1 over denominator (x plus 1 )cubed end fraction space x greater than 0 What is the probability the person's reaction time will be between 0.9 and 1.1 seconds
Answer:
the probability is 0.0378
Step-by-step explanation:
Given that;
cumulative distribution function: F (x ) = 1 - ( 1 / ( x + 1)³ )
probability the person's reaction time will be between 0.9 and 1.1 seconds will be;
p( 0.9 < x < 0.9 ) = F( 1.1 ) - F( 0.9 )
p( 0.9 < x < 0.9 ) = [1 - ( 1 / ( 1.1 + 1)³ )] - [1 - ( 1 / ( 0.9 + 1)³ )]
= [1 - ( 1 / ( 2.1)³ )] - [1 - ( 1 / ( 1.9)³ )]
= [1 - 0.107979] - [1 - 0.14579]
= 0.8920 - 0.8542
= 0.0378
Therefore, the probability is 0.0378
