Answer:
tan (A−B)=tan(A)−tan(B)/1+tan(A)tan(B)tan(A−B)=tan(A)−tan(B)/1+tan(A)tan(B)
1+tan(A)tan(B) To prove this, we should know that:
1+tan(A)tan(B) To prove this, we should know that:sin(A−B)=sin(A)cos(B)−cos(A)sin(B)
1+tan(A)tan(B) To prove this, we should know that:sin(A−B)=sin(A)cos(B)−cos(A)sin(B)AND
1+tan(A)tan(B) To prove this, we should know that:sin(A−B)=sin(A)cos(B)−cos(A)sin(B)ANDcos(A−B)=cos(A)cos(B)+sin(A)sin(B)
1+tan(A)tan(B) To prove this, we should know that:sin(A−B)=sin(A)cos(B)−cos(A)sin(B)ANDcos(A−B)=cos(A)cos(B)+sin(A)sin(B)We start with:
1+tan(A)tan(B) To prove this, we should know that:sin(A−B)=sin(A)cos(B)−cos(A)sin(B)ANDcos(A−B)=cos(A)cos(B)+sin(A)sin(B)We start with:tan(A−B)=sin(A−B)/cos(A−B)
cos(A−B)tan(A−B)=sin(A)/cos(B)−cos(A)sin(B)cos(A)cos(B)+sin(A)sin(B)(1)
cos(B)−cos(A)sin(B)cos(A)cos(B)+sin(A)sin(B)(1)We would want to divide both numerator and denominator by cos(A)cos(B)
cos(B)−cos(A)sin(B)cos(A)cos(B)+sin(A)sin(B)(1)We would want to divide both numerator and denominator by cos(A)cos(B)but there are 4 cases,

3. Sandi is making curtains for her bedroom. She needs 58 feet of fabric. She has 14 yards of fabric. How many more yards of fabric does she need?
Answer:
she needs 3 1/3 more yards
Step-by-step explanation:
There are 3 feet in a yard
14yards x 3feet = 42 feet
58 feet- 42 feet= 10 feet
10 divded by 3 is about 3.3
Answer: 6 yards
Step-by-step explanation:
1) 14 x 3 = 42
2) 58 - 42 = 16
3) 16 / 3 = 5.33333333....
4) round up = 6

Find the percent change. Tell whether it is a percent increase or decrease.
from 84 to 63
A. 25% decrease
B. 33% increase
C. 25% increase
D. 33% decrease
a. 2 - 4 x 6 + 8 + 2 =
b. 6 + 2 x 4 - 8 + 10 =
The answer would be
A.) ~-12~
because 2-24=-22 -22+8+2=-12
B.)~16~
because 6+8-8+10 and -8+8=0 so 6+10=16

Braxton has money in a savings account. The equation B = 800(1+0.03)'.
can be used
to calculate the amount of money in dollars, B, Braxton has in his account after t years since
opening the account.
Pam also has money in a savings account. The equation P = 800(1 + 0,04) can be
used to calculate the amount of money in dollars, P, Pam has in her account after t years
since opening the account.
Choose from the drop down menus to correctly complete each sentence.
Braxton's initial investment Choose...
Pam's initial investment.
The interest on Braxton's account Choose...
the interest on Pam's account.
Answer:
a) Braxton's initial investment is equals to (=) Pam's initial investment.
b)The interest on Braxton's account is less than (< ) the interest on Pam's
account.
Step-by-step explanation:
Given - Braxton has money in a savings account. The equation
B = [tex]800(1 + 0.03)^{t}[/tex] can be used to calculate the amount of money
in dollars, B, Braxton has in his account after t years since opening
the account. Pam also has money in a savings account. The
equation, P= [tex]800(1 + 0.04)^{t}[/tex] can be used to calculate the amount of
money in dollars, P, Pam has in her account after t years since
opening the account.
To find - a) Braxton's initial investment ..........Pam's initial investment.
b) The interest on Braxton's account .....the interest on Pam's
account.
Proof -
As given, Broxton equation is -
Pam equation is -
Now,
a.)
For initial investment , Put t = 0
⇒B = [tex]800(1 + 0.03)^{0} = 800(1) = 800[/tex]
P = [tex]800(1 + 0.04)^{0} = 800(1) = 800[/tex]
We can see that for t = 0
Initial investment of Braxton = Initial investment of Pam
⇒Braxton's Initial investment = Pam's initial investment.
b.)
For the interest,
As we have not given any time period for which the interest has to be find.
So , let the time period , t = 5 years
Therefore,
B = [tex]800(1 + 0.03)^{5} = 800(1.03)^{5} = 800(1.159) = 927.42[/tex]
P = [tex]800(1 + 0.04)^{5} = 800(1.04)^{5} = 800(1.217) = 973.32[/tex]
Now,
Interest on Braxton's account = 927.42 - 800 = 127.42 ≈ 127
Interest on Pam's account = 973.32 - 800 = 173.32 ≈ 173
∴ we get
The interest on Braxton's account is less than the interest on Pam's account.
Write an equation of a like that passes through the points (9,5) and (6,7)
Answer:
y=-2/3x+11
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(7-5)/(6-9)
m=2/-3
m=-2/3
y-y1=m(x-x1)
y-5=-2/3(x-9)
y=-2/3x+18/3+5
y=-2/3x+6+5
y=-2/3x+11
Determine the 10th term of the sequence –17, -13,-9, ...
A. 19
B. -53
C. 36
D. 53
Answer:
-53 (answer : B)
Step-by-step explanation:
hello :
this the arithmetic sequence because :
(-9)-(-13)=(-13)-(-17)= 4 (common difference)
the first term is : A1 = -17
the nth term of an arithmetic sequence is :
An= A1 +(n-1)d ....a common difference is : d
the 10th term is : A10
A10= -17 +(10-1)(4) = -17-36 = -53 (answer : B)

[tex]6^{2} +2^{2} =c^{2} \\36+4=c^{2} \\40=c^{2} \\\sqrt{40} =c\\c=6.32[/tex]
Answer:
Square root of 40, I don't know what the brace is
Step-by-step explanation:
To find side c, you have to use the Pythagorean theorem. A^2+B^2=C^2. In this case A and B are 6 and 2. This means the equation would be 6^2+2^2=C^2. Simplify this to get 36+4=C^2. Add 36 and 4 to get 40. 40=C^2. This would mean that it is square root of 40.
