Step-by-step explanation:
Find the value of tan Θ is sin Θ = 1/2 90° ≤ Θ ≤ 180°
a. -√3/2
b. -√3/3
c. √3/2
d. √3/3
9514 1404 393
Answer:
b. -√3/3
Step-by-step explanation:
From your knowledge of the values of trig functions of special angles, you know sin(30°) = 1/2. For an angle in the second quadrant, this means the reference angle is 30° and the actual angle measure is 180° -30° = 150°.
The corresponding value of the tangent function is -√3/3, negative in the second quadrant.
Answer:
sin theta=p/h=1/2 let p=1k and h=2k
tan theta=p/b=1k/(√(2k)²-k²)=1k/k√3=1/√3
=tan 30
therefore theta =30°
your answer is 1/√3=√3/3

What is Trigonometry?The branch of mathematics concerned with specific functions of angles and their application to calculations. In trigonometry, there are six functions of an angle that are often utilised. Sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant are their names and acronyms (csc).
Given:
B = 8
Using Trigonometry
tan 29 = P/ B
0.554 = P / 8
P = 8 x 0.554
P = 4.432
Hence, the measure for BC is 4.432

Step-by-step explanation:
Stella is using grid paper to make shapes. Her first shape has an area of 14 square units. Her second shape has an area of 28 square units. Her third shape has an area of 42 square units. If this pattern continues what will be the area of her fourth shape
Answer:
56
Step-by-step explanation:
The pattern is an arithmetic sequence:
by the first three terms, the common difference is:
28-14=42-28=14
So the next pattern would be:
14+42=56
By the equation x = a + d ( n - 1 )
Substituting when n=1, x=14 and when n=2 x=28
a = 14 and d = 14
x = 14 + 14 ( n - 1 )
substituting n = 4
x = 14 + 14 ( 4 - 1 )
x = 56
28÷14=42-28=14+42=56

How many numbers between 75 and 500 are divisible by 7
9514 1404 393
Answer:
61
Step-by-step explanation:
75 = 10×7 +5
500 = 71×7 +3
All the multiples of 7 between the 10th and the 71st (including the 71st, but not the 10th) are numbers in the range that are divisible by 7.
61 numbers in the interval [75, 500] are divisible by 7.
Jessica has an account with a credit union her account earns 2.7% simple interest yearly exactly a year and a half ago she opened her account with $900 how much interest has she earn a far
Answer:
Account balance after interest is added : A = P(1 + rt)
Interest : I = A - P
R = 2.7% per year
P = $900.00
t = 1.5 years
First, converting R percent to r a decimal
r = R/100 = 2.7%/100 = 0.027 per year.
Solving our equation:
A = 900(1 + (0.027 × 1.5)) = 936.45
A = $936.45
Interest : I = A - P = $36.45

The graph of g(x), shown below, resembles the graph of f(x) = x - x2, but it
has been changed somewhat. Which of the following could be the equation
of g(x)?
Anxx
O A. f(x) = (x + 2)4 - (x + 2)2
B. f(x) = x - x2-2
C. f(x) = (x - 2)4 - (x - 2)2
O D. f(x) = x - x2 + 2
Answer:We are given function f(x) = x^4 - x^2.
We need to find the equation of function g(x) according to shown graph.
We can apply rules of transformation to get the function g(x) by using given graph.
Function g(x) graph is being shift a half or 0.5 units up of the graph f(x).
When graph shift k units up, we add k to given function.
Where k is some constant.
In the graph f(x) is being shifted 0.5 units up.
So, we would add 0.5 in f(x) = x^4 - x^2 function.
On adding 0.5 we get
g(x) = f(x)+0.5 = = x^4 - x^2 +0.5.
Therefore, correct option is second option.
g(x) = x^4 - x^2 +0.5.

-6x - 3h
Step-by-step explanation:
Write as a function.
[tex]f(x)=-3x^{2}+3[/tex]
Consider the difference quotient formula.
[tex]\frac{f(x+h)-f(x)}{h}[/tex]
Find the components of the definition.
[tex]f(x+h)=-3h^{2}-6hx-3x^{2}+3\\f(x)=-3x^{2}+3[/tex]
Plug in the components.

Nathan buys 8 bottles of iced tea at the grocery store. He has coupons for $0.35 off the regular price of each bottle. After using the coupons, the total cost of the drinks is $7.20.
Which equation can be used to find the regular price, p, of each bottle of iced tea?
Answer:
$1.25
Step-by-step explanation:
0.35 x 8 = 2.80
7.20 + 2.80 = 10
10 divided by 8 = 1.25
Thank you :)
The equation that can be used to determine the regular price of iced tea is p = 1/8($7.20 - $2.80).
Description of couponsCoupons reduce the price of an item. An item becomes cheaper when coupons are used. Thus, Nathan would buy the iced teas at a cheaper price as a result of the coupons.
Equation that represents the regular price of the iced tea.Discounted price = regular price - discount
$7.20 = p - ($0.35 x8)
$7.20 = p - $2.80
p = $7.20 - $2.80
Price of each bottle = p = 1/8( $7.20 - $2.80)
