First, note that ΔTVW is a right triangle.
Since we are given that ∠UTV is 112°, this means that ∠WTV is 68° because 180-112 is 68°.
Now that we know ∠WTV is 68°, we can use the basic trigonometric ratios to solve for VW. VW is the side opposite ∠WTV. We also know the hypotenuse. So, we would use sine. Recall that:
[tex]\sin(\theta)=opp/hyp[/tex]
Plug in 68° for theta, VW for the opposite, and 15 for the hypotenuse:
[tex]\sin(68)=VW/15\\VW=15\sin(68)\\VW\approx13.9078\approx13.9[/tex]

the diagram above shows a rectangle inscribed in a circle AB=10 and AC =12 caculate the total surface area of the shaded part
Answer:
[tex]71.63 \: \: \mathrm{cm^2 }[/tex]
Step-by-step explanation:
Once we know the diameter of the circle, we can figure out the problem.
The diameter of the circle = The diagonal of the rectangle inscribed in the circle
To find the diagonal of the rectangle, we can use a formula.
[tex]d=\sqrt{w^2 + l^2}[/tex]
The width is 10 cm and the length is 12 cm.
[tex]d=\sqrt{10^2 + 12^2}[/tex]
[tex]d \approx 15.62[/tex]
The diagonal of the rectangle inscribed in the circle is 15.62 cm.
The diameter of the circle is 15.62 cm.
Find the area of the whole circle.
[tex]A=\pi r^2[/tex]
The [tex]r[/tex] is the radius of the circle, to find radius from diameter we can divide the value by 2.
[tex]r = \frac{d}{2}[/tex]
[tex]r=\frac{15.62}{2}[/tex]
[tex]r=7.81[/tex]
Let’s find the area now.
[tex]A=\pi (7.81)^2[/tex]
[tex]A \approx 191.625[/tex]
Find the area of rectangle.
[tex]A=lw[/tex]
Length × Width.
[tex]A = 12 \times 10[/tex]
[tex]A=120[/tex]
Subtract the area of the whole circle with the area of rectangle to find area of shaded part.
[tex]191.625-120[/tex]
[tex]71.625 \approx 71.63[/tex]
The percent of a country's households with broadband Internet access can be modeled by the function f left parenthesis x right parenthesisequalsnegative 0.11 x squared plus 6.51 x plus 3, where f left parenthesis x right parenthesis is the projected percent of households with broadband Internet access and x is the number of years since 2000.
a. Will this function have a maximum or a minimum? How can you tell?
b. According to this model, in what year will the percent of homes with broadband Internet access be at its maximum or minimum?
c. What is the predicted maximum/minimum percent of homes with broadband Internet access?
Answer:
a) The function has a maximum at x = 29,59
b) 99,32 %
Step-by-step explanation:
f(x) = -0,11*x² + 6,51*x + 3
Then:
f´(x) = -0,22*x + 6,51
If f´(x) = 0 then - 0,22*x + 6,51 = 0
0,22*x = 6,51
x = 6,51/0,22 ⇒ x = 29,59
if we get the second derivative
f´´(x) = - 0,22 f´´(x) < 0 then we have a maximun at x = 29,59
a) the function has a maximum
b) 29,59 years after 2000 ( in 2030 )
c) f(x) = - 0,11*x² + 6,51*x + 3
f(29,59) = - (0,11)* (29,59)² + 6,51*29,59 + 3
f(29,59) = 99,32 %
A rectangle has a perimeter of 35.8 inches and a base of 12.6 inches. What is the height?
Answer:
Height is 5.3 inches.
Step-by-step explanation:
2* base + 2*height = 35.8
2*12.6 + 2h = 35.8
h = (35.8 - 2(12.6) / 2
= (35.8 - 25.2) /2
= 10.6 / 2
= 5.3 inches.
Answer:
5.3inStep-by-step explanation:
The formula of a perimeter of a rectangle:
[tex]P=2(l+w)[/tex]
l - length
w - width
We have
[tex]P=35.8in\\l=12.6in[/tex]
Substitute:
[tex]35.8=2(12.6+w)[/tex] divide both sides by 2
[tex]\dfrac{35.8}{2}=\dfrac{2(12.6+w)}{2}[/tex]
[tex]17.9=12.6+w[/tex] subtract 12.6 from both sides
[tex]17.9-12.6=12.6-12.6+w\\\\5.3=w\to w=5.3\ (in)[/tex]

What is the smallest value of x that satisfies the equation 8x^2 - 38x + 35 = 0? Express your answer as a decimal.
Answer:
1.25
Step-by-step explanation:
8x² -38x + 35 = 0
8x² - 10x - 28x + 35 = 0
2x(4x - 5)-7(4x - 5) = 0
(4x−5)(2x−7) = 0
4x - 5 = 0 or 2x - 7 = 0
x = 5/4 or x = 7/2
x = 1.25 or 3.5
Smallest value being = 1.25

What does it mean to say that a data point has a residual of -1?
A. The point lies 1 unit above the regression line.
B. The point lies directly on the regression line.
C. The point lies 1 unit below the regression line.
O D. The predicted value for that point is -1.
I'm sorry if it's wrong but i think it's C.
Answer:
C. The point lies 1 unit below the regression line.
Step-by-step explanation:
A residual is calculated by doing the true value minus the predicted value. For instance, if a point's true value is 5, but the predicted value is 3, the residual of the point will be 5 - 3 = 2.
The regression line is the line of predicted values. So, if a data point has a residual of -1, that means that the predicted value overpredicted the point's value. So, the point will lie C. 1 unit below the regression line.
Hope this helps!
How many seconds will elapse between seeing lightning and hearing the thunder if the lightning strikes 5.0 mi (26,400 ft) away and the air temperature is 83.6°F?
Answer:
Time taken = 23.10 sec (Approx)
Step-by-step explanation:
Given:
Distance of lighting = 5 mi = 26,400 ft
Air temperature =83.6°F = 28.67°FC
Computation:
Speed of the sound
V = 331 + 0.61 × T
V = 331 + 0.6 × 28.67
V = 348.202 m/s
Distance = 5 mi = 8,046.72 m
Time taken = Distance / Speed
Time taken = 8,046.72 / 348.202
Time taken = 23.10 sec (Approx)

Step-by-step explanation:
Tristan wants to buy a car and has a choice between two different banks. One bank is offering a simple interest rate of 3% and the other bank is offering a rate of 2.5% compounded annually. If Tristan decides to deposit $7,000 for 4 years, which bank would be the better deal? 1. a simple interest rate of 3% 2. a compound interest rate of 2.5%
Answer:
The bank offering simple interest at rate of 3% for four years
Step-by-step explanation:
Hello,
To find out which deal would be better, we have to find how much accrued on the simple and compound interest.
Data;
Principal (P) = $7,000
Time = 4 years
Simple interest rate = 3%
S.I = PRT / 100
S.I = (7000 × 3 × 4) / 100
S.I = $840
In four years, he would have $7000 + $840 = $7840.
For compound interest,
C.I = P(1 + r/n)^nt
Where n = number of time compounded = 1 (since it's annually)
rate = 2.5% = 2.5/ 100 = 0.025
C.I = 7000(1 + 0.025/1)⁽¹*⁴⁾
C.I = 7000 (1 + 0.025)⁴
C.I = 7000×(1.025)⁴
C.I = 7000 × 1.1038
C.I = $7726.6
In four years he would have $7,726.6
After calculating and evaluating both option, it's advisable for him to select the bank offering a simple interest of 3% for four years

Answer:
A) False
B) True
Step-by-step explanation:
For A) First let's do x/11 = 15. If you solved it by now, you will know that the answer is 0.7333333. So now you just do 11x15. Because the answer is different then the answer we got when doing the division, the answer for A is false
For B) B is definitely true because equation are any mathematical sentences that have an equation symbol. So it's like saying 8x3=24 and 6x4=24. These two equations end up with the same answer so B is true.
I hope this helped you find out the rest :)

The art club is planning a meeting. They are planning to serve cookies and brownie bites and want to have one dessert per person. They expect an attendance of a total of 75 people. Cupcakes (c), come in packs of 6 each, and the brownie bites (b) come in packages of 15. (here is the equation > 6c+15b=75).
Question #1) If the treasurer buys 1 package of brownie bites, how many packages of cupcakes are needed according to this equation? Question #2) If the treasurer buys 7 packages of brownie bites, how many packages of cupcakes are needed according to this equation?
Answer:
see explanation
Step-by-step explanation:
1) 6c + 15(1) = 75
6c = 60
c = 10 packs of cupcakes
2) 6c + 15(7) = 75
6c + 105 = 75
6c = -30
c = -5, since he bought more brownies than needed, he does not need to buy any cupcakes.
Answer:
6c+15b=75
1)If the treasurer buys 1 package of brownie bites
6(1)+15b=75
15b=75-6
b=69/15=4.6 ( means the treasure needs to buy 5 packages).
2): If the treasurer buys 7 packages of brownie bites,
6c+15(7)=75
6c+105=75
c=-30/6=-5( you can not buy negative amount)
the treasure does not need to buy, because brownies are enough and more.
a circular garden has a diameter of 6 yards.What is the area of the garden. Use 3.14
Answer:
28.26 yd^2
Step-by-step explanation:
A = 3.14 • r^2
Radius is half of the diameter, so 3.
A = 3.14 • 3^2
A = 3.15 • 9
A = 28.26 yd^2
Answer: The area of the garden is 28.26
Step-by-step explanation:
1. Divide the diameter in half, that gives you the radius, in this case: 3
2. Use the formula for finding the area with the radius: A= π r², and use 3.14 instead of pi. Multiply 3.14 by 3²
3. You should get 28.26 as your answer.
