The value of tan (A-pi/4) is (-√(15)- 1) / 1 -√(15).
What is Tan(a - b) Identity in Trigonometry?One of the trigonometric identities for compound angles is the tan(a-b) identity. When the angle for which the tangent function value is to be determined is supplied in the form of the difference of any two angles, it is used. The compound angle is denoted by the angle (a-b) in the formula for tan(a-b).
Given:
tanA = -square root 15
tanA = -√(15)
To find the value of tan (A-pi/4):
Use the formula,
Tan(a - b) Identity
tan(A-B) = (tanA - tanB) / 1 + (tanAtanB)
Substituting the values,
tan(A-π/4) = (tanA - tanπ/4) / 1 + (tanAtanπ/4)
tan(A-π/4) = (-√(15)- 1) / 1 + (-√(15)
tan(A-π/4) = (-√(15)- 1) / 1 + (-√(15)
tan(A-π/4) = (-√(15)- 1) / 1 -√(15)
Therefore, the value is tan(A-π/4) = (-√(15)- 1) / 1 -√(15)

What is the solution set to the equation (3x−9)(5x−3)=0?
{35,3}
{3}
{35,53}
{−3,−35}
Answer:
{ [tex]\frac{3}{5}[/tex], 3 }
Step-by-step explanation:
Given
(3x - 9)(5x - 3) = 0
Equate each factor to zero and solve for x
3x - 9 = 0 ( add 9 to both sides )
3x = 9 ( divide both sides by 3 )
x = 3
and
5x - 3 = 0 ( add 3 to both sides )
5x = 3 ( divide both sides by 5 )
x = [tex]\frac{3}{5}[/tex]

Step-by-step explanation:
Jackson's car was making a rumbling noise for 2 weeks. He decided to take it to the mechanic to get it checked out. To diagnose the problem, the mechanic tells Jackson that he charges a flat, one-time fee of $60 and then $35 for each hour he spends trying to identify the problem. What is the slope in this scenario?
Answer:
The slope is 35
Step-by-step explanation:
Given
[tex]One\ Time\ Fee = \$60[/tex]
[tex]Hourly\ Rate = \$35[/tex]
Required
Determine the slope
First, we need to determine the equation.
Let y represents the total charges and x represents the number of hours.
y is calculated using;
[tex]y = One\ Time\ Fee + Hourly\ Rate * x[/tex]
This gives:
[tex]y = 60 + 35* x[/tex]
[tex]y = 60 + 35x[/tex]
Reorder
[tex]y =35x + 60[/tex]
The general form of an equation is:
[tex]y =mx + b[/tex]
Where m represents the slope
By comparison of [tex]y =mx + b[/tex] and [tex]y =35x + 60[/tex]
[tex]m = 35[/tex]
Hence, the slope is 35

The value of the tanB is root of 21/2
We have given that ,
C is 90 degrees and side AB=5 units and CB=2 units
We have to find the tan B
We have given that the right angle triangle.
What is the value of tan ratio?
[tex]tan\theta=\frac{opposite side}{adjucent side}[/tex]
Here opposite side side of B is AC and adjacent side of B is CB.
We know the side AB=5 units and CB=2 units
First we have to find the side AC
Therefore by using Pythagoras theorem,
[tex]AB^2=CB^2+AC^2[/tex]
[tex]AB^2-CB^2=AC^2\\25-4=AC^2\\21=AC^2\\[/tex]
Taking square root on both side we have
[tex]\sqrt{21}=AC\\ AC=\sqrt{21}[/tex]
Now we have the tan ratio,
[tex]tan\theta=\frac{opposite side}{adjucent side}\\\\tanB=\frac{AC}{CB}\\\\tanB=\frac{\sqrt{21} }{2}\\[/tex]
Therefore the option F is correct.
The value of the tanB is root of 21/2.

A car is merging onto a freeway (beginning at rest), accelerating at a constant rate of 10ft/sec2. How long does it take to reach merging speed at 70mph?
Answer:
10.3secondsStep-by-step explanation:
Step one:
given data
acceleration,a= 10ft/sec^2
final velocity v= 70mph
first, let is convert mph to ft/sec
1mph is 1.46667 ft/sec
70 mph is x
cross multiply we have
x= 102.7ft/s
Step two:
we are using the first equation of motion
v=u+at
initial velocity u= 0m/s
102.7=0+10*t
102.7=10t
divide both sides by 10
t=10.3seconds

Sarah and Jean were able to sell 4 dozen of cupcakes in a hour at a school fair if this rate continue how many dozen s of cupcakes well they be able to sell if the school fair 5 at 9:00 am and ends in 5:00 pm
Answer:
Step-by-step explanation:
Firstly,
We can tell by reading the question that they sell 48 cupcakes witch is 4 dozens every hour so if they continue to sell at that same rate then:
There are 8 hours between 9am and 5pm
∴ It is 48:1
That means 48 cupcakes per hour this is equation is a direct proportion so if any number increases so will the other
So if it is 48:1 then x:8 with be = 48x8
∴ Sarah and Jean will be able to sell 384 cupcakes
