Find sin j? Please I don’t understand
=========================================================
Explanation:
The sine ratio involves the opposite over hypotenuse.
With respect to reference angle J, the opposite leg is the one furthest from the angle. So the opposite side is KL = 4. The hypotenuse is always the longest side, always opposite the 90 degree angle, so LJ = 8 is the hypotenuse.
sin(angle) = opposite/hypotenuse
sin(J) = KL/LJ
sin(J) = 4/8
sin(J) = 0.5
n-18=100 can somebody answer
Answer:
n = 118
Step-by-step explanation:
Add 18 to both sides of the equation:
n = 100 + 18n = 100 + 18
Add 100 and 18.
n = 118
If someone watching at movie that was 2 hours and 35 minutes long and finished watching at 5:30pm .What time did the movie began
Answer: 2:55 PM
Step-by-step explanation:
Given
The length of the movie is 2 hour and 35 minutes
If the movie is finished at 5:30 PM
First, subtract 2 hours from the finishing time i.e.
[tex]=5:30\ \text{PM}-2\ \text{hr}\\=3:30\ \text{PM}[/tex]
Now, subtract 35 minutes into two parts i.e. 30 min and 5 min from 3:30 PM
[tex]=3:30\ \text{PM}-30\ \text{min}\\=3:00\ \text{PM}[/tex]
remaining 5 min
[tex]=3:00\ \text{PM}-05\ \text{min}\\=2:55\ \text{PM}[/tex]
Thus, the starting time is 2:55 PM

Step-by-step explanation:
i need help with negative poimts
Answer:
What part do you need help with? Is there a specific problem?
Step-by-step explanation:
One side of right angled triangle is 10 cm the other are both of length x ,calculate x to 2 decimal places
As triangle is right angled, we can possibly use the Pythagoras theroam.
By pythgoras theoram;
= H² = B² + P²
= 10² = x² + x²
= 10² = x⁴
=⁴√ 10² = x
= 10²×¼ = x
= 10½ = x
= √10 = x
= 3.16 = x
So the value of x is 3.16 cm
(Hypotenuse)² = (Base)²+ (Perpendicular)²
Taking, Hypotenuse As H
Base As B
Perpendicular As P
_________________________
Solving The QuestionH= 10cm
B= x cm
P= x cm
__________
H²= B²+P²
10²= x²+x²
=> 100= 2x²
=> √100= 2x
=> 10=2x
=> x=10/2
=> x= 5
Hope This Helps You ❤️A polynomial function has a degree of 8. What is the maximum number of turning points?
Answer:
7
Step-by-step explanation:
To find the maximum number of turning points of any polynomial function, subtract one from the degree.
Since the degree is 8, subtract 1 from this:
8 - 1
= 7
So, the maximum number of turning points is 7.

Give the following sequence for f(x) = 4x^2 - x , when x is -4, 1, 2
O 58, 14, 3
0-64, - 14, 3
O 68, 14, 3
0 7, 14, 3
Answer:
O 68, 14, 3
Step-by-step explanation:
Given:
f(x) = 4x² - x
When x = -4
f(x) = 4x² - x
= 4(-4)² - (-4)
= 4(16) + 4
= 64 + 4
f(x) = 68
When x = 1
f(x) = 4x² - x
= 4(1)² - 1
= 4(1) - 1
= 4 - 1
f(x) = 3
When x = 2
f(x) = 4x² - x
= 4(2)² - 2
= 4(4) - 2
= 16 - 2
f(x) = 14
The answer = 68, 3, 14

A certain restaurant sells cups of coffee for $2 and donuts for $1.50. If the restaurant sold a total of 80 items and earned $141.50, how many donuts did the restaurant sell?
Answer: 37 donuts
Step-by-step explanation:
coffee for 2,
donuts for 1.5
c = coffee
d = donuts
lets make an equation
c*2 + (80-c)*1.5 = 141.5
from this we get:
c= 43.
if c = 43, then d is 80-43 = 37.
they sold 43 coffees, and 37 donuts.
lets check the math
43*2+37*1.5 = 141.5. math checks out

Step-by-step explanation:
In order to help students improve their reading, a school district decides to implement a reading program. It is to be administered to the bottom 5% of the students in the district, based on the scores on a reading achievement exam. If the average score for the students in the district is 122.6, find the cutoff score that will make a student eligible for the program. The standard deviation is 18. Assume the variable is normally distributed. Round to two decimal places.
Answer:
92.99
Step-by-step explanation:
Mean, μ = 122.6
Standard deviation, σ = 18
Recall :
Z = (x - μ) / σ
x = score
The Zscore for the lower 5% = 0.05
Using, invnorm(0.05) = - 1.645
Put Z = - 1.645
-1.645 = (x - 122.6) / 18
-1.645 * 18 = x - 122.6
-29.61 = x - 122.6
-29.61 + 122.6 = x
x = 92.99

Consider functions f and g.
Which expression is equal to f(x) ⋅ g(x) ?
Answer:
C
x-2 / x+6
Step-by-step explanation:
I did the math
(I am not 100% sure though, so if I am wrong, someone please mention it!)
The function f(x) . g(x) is a composite function, and the value of f(x) . g(x) is (x- 2)/(x + 6)
What is a composite function?A composite function is a function formed by combining multiple independent functions
The functions f(x) and g(x) are given as:
[tex]f(x) = \frac{x + 12}{x^2 + 4x- 12}[/tex]
[tex]g(x) = \frac{4x^2 - 16x+ 16}{4x+ 48}[/tex]
The composite function f(x) . g(x) is calculated using:
[tex]f(x) \cdot g(x) =\frac{x + 12}{x^2 + 4x- 12} * \frac{4x^2 - 16x+ 16}{4x+ 48}[/tex]
Expand the functions
[tex]f(x) \cdot g(x) =\frac{x + 12}{x^2 + 4x- 12} * \frac{4(x^2 - 4x+ 4)}{4(x+ 12)}[/tex]
Cancel out the common factors
[tex]f(x) \cdot g(x) =\frac{1}{x^2 + 4x- 12} * \frac{x^2 - 4x+ 4}{1}[/tex]
Further, expand
[tex]f(x) \cdot g(x) =\frac{1}{(x -2)(x + 6)} * \frac{(x - 2)(x - 2)}{1}[/tex]
Cancel the common factors
[tex]f(x) \cdot g(x) =\frac{x- 2}{x + 6}[/tex]
Hence, the value of f(x) . g(x) is (x- 2)/(x + 6)
