Answer:
[tex]\frac{c}{a}[/tex] and [tex]\frac{b}{a}[/tex]
Step-by-step explanation:
sinB = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{AC}{BC}[/tex] = [tex]\frac{b}{a}[/tex]
tanC = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{AB}{AC}[/tex] = [tex]\frac{c}{b}[/tex]
Thus
sinB tanC = [tex]\frac{b}{a}[/tex] × [tex]\frac{c}{b}[/tex] ( cancel b on numerator/ denominator )
= [tex]\frac{c}{a}[/tex]
---------------------------------------------------------------------------
sinC = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{AB}{BC}[/tex] = [tex]\frac{c}{a}[/tex]
tanB = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{AC}{AB}[/tex] = [tex]\frac{b}{c}[/tex]
Thus
sinC tanB = [tex]\frac{c}{a}[/tex] × [tex]\frac{b}{c}[/tex] ( cancel c on numerator/ denominator )
= [tex]\frac{b}{a}[/tex]

Exit Ticket: At noon, a tank has a water depth of 9 in. After 3 hours, the depth was 8 inches. At 6pm, the depth was 7 inches. What is the initial value for the function? help will be appreciated.
Answer:
Step-by-step explanation:
The straight line equation is:
y = m*x + b Where m is the slope of the line and b the intercept with y-axis, in our case y is the depth of the tank and x (time in lapsus of 3 hours).
The slope m = ( y₂ - y₁ ) / (x₂ - x₁)
We have point A ( 3 , 8 ) and point B ( 6 , 7 )
m = ( 6 - 3 ) / (7 - 8 ) m = -3
We see that each 3 hours time-depth decreases 1 in.
Then to find the depth at the beginning of x-axis
At noon 12 tank was 9 inches, three hours before at 9 in the morning the depth was 10 inches and:
9 in the morning 10
6 in the morning 11
3 in the midnight 12
12 in the night 13
Then 13 is the intercept with y-axis
then the equation is:
h = - 3*x + 13
Note x is time in lapsus of 3 hours

Xander writes math textbooks that sell x dollars each. he received a bonus of $25,000 for signing a contract, and he receives 8% commission on each book sale. express the total amount of income xander earns from selling y books algebraically
The total amount of income Xander earns from selling y books algebraically is C = 25000 + xy + 0.08y.
What is an equation?An equation is the statement that illustrates the variables given. In this case, two or more components are taken into consideration to describe the scenarios.
In this situation, Xander writes math textbooks that sell x dollars each, he received a bonus of $25,000 for signing a contract, and he receives 8% commission on each book sale.
c = total amount
y = number of books.
The total amount of income will be:
= 25000 + (x × y) + (8% × y)
= 25000 + xy + (0.08 × y)
C = 25000 + xy + 0.08y

Answer:
Option D: Multiply the second equation by 4 and then add the result to the first equation is the correct answer.
Step-by-step explanation:
Given that:
x-4y = 2
2x+y = 12
For elimination, one of the variable is eliminated.
In this system,
we can either multiplying the first equation by 2 or second equation by 4.
Then we can add the equations.
By multiplying the second equation with 4 and then adding both equations, we can eliminate the variable y.
4(2x+y=12)
8x+4y=48
By adding
(x-4y)+(8x+4y)=2+48
7x=48
Hence,
Option D: Multiply the second equation by 4 and then add the result to the first equation is the correct answer.

Which of these r-values represents the strongest correlation? O A. -0.7 Caty B. -0.6 O C. -0.4 O D. -0.5
Answer:
-0.4
Step-by-step explanation:
its that one
The strongest correlation is -0.4.
Option C is correct.
What is correlation?Correlation is a statistical term that expresses how closely two variables are related linearly (meaning they change together at a constant rate). It's a typical tool for describing simple relationships without stating a cause and effect link.
When the result is closer to +1 (positive correlation) or -1 (negative correlation), the strongest correlation is considered (negative correlation).
A positive correlation coefficient means that the value of one variable is directly related to the value of another.
Here -0.4 is the closest value to 1.
So, the strongest correlation is -0.4.

The graph shows gas mileage for a car. What is the unit rate?
A)

miles per gallon
B)
miles per gallon
27
09
27 miles per gallon
D)
54 miles per gallon
Answer:
The unit rate = 27 miles per gallon.
Hence, option C is true.
Step-by-step explanation:
From the given line graph:
Taking two points
(2, 54)(6, 162)The unit rate can be determined by finding the rate of change or slope between the points (2, 54) and (6, 162)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(2,\:54\right),\:\left(x_2,\:y_2\right)=\left(6,\:162\right)[/tex]
[tex]m=\frac{162-54}{6-2}[/tex]
Refine
[tex]m=27[/tex]
Therefore, the unit rate = 27 miles per gallon.
Hence, option C is true.

Can y’all plz help me ?
Answer:
x=-5
Step-by-step explanation
The first box has eight x's and six 1's which means that it would be written as 8x+6
The second box has four x's and fourteen -1's which means that it would be written as 4x-14
You set them equal to one another
8x+6=4x-14
You subtract 4x from both sides
4x+6=-14
Subtract 6 on both sides
4x=-20
Divide 4 on both sides
x=-5
