Answer:
Please check explanations
Step-by-step explanation:
Using the difference of two squares, the lowest common multiple becomes;
1-sin^2 a
Thus, we have that;
cos a (1-sin a) + cos a (1 + sin a) /1 - sin^2 a
1 - sin^2 a = cos^2 a
That means;
{cos a - cos a sin a + cos a + cos a sin a}/ cos^2 a
= 2cos a / cos^2 a
= 2/cos a
but 1/cos a = sec a
Thus;
2/ cos a = 2 sec a
A customer wants to purchase a sweater from a store.
• The original price of the sweater is $40.
• The sweater is on sale for 20% off the original price.
• A sales tax of 5% is applied after the discount.
What was the final price of the sweater?
Answer:
$33.60
Step-by-step explanation:
multiply 40 by 0.20 = 8 subtract 8 from 40= 32 x 0.05 is 1.6 so its 33.6

Answer:
1000 = 125 /65536
Step-by-step explanation:
Rewrite the expression using the negative exponent rule and then Raise
2 to the power of 21 . Cancel the common factor of 32. Combine 125 and 1 /65536
Answer:
Equation is incorrect
Answer (If you did the math):
1000 = 4000/2^21 or 1000 = 125/65536
Step-by-step explanation #1:
1. We know that 1000 is equal to 4000 * 1/4, meaning that the parenthesis is equal to 1/4. 1/4 is 2^-2 (Look below), and since 2^-21 does not equal 2^-2, so this equation is incorrect.
In a situation where:
[tex]y^{- x}[/tex] and -x is negative ------> [tex]y^{-x} = 1/y^{x}[/tex] (And Vice Versa)
Step-by-step explanation #2 (If you did the math):
Open the parenthesis and make the 2^-21 into a fraction. This would be 1/2^21, which you would then multiply by 4000 to get 4000/2^21. You can now use a fraction calculator to calculate this value in fraction. 4000/2^21 simplifies to 125/65536.

-5 = -3(x + 11) HELPP
Answer: x=9 1/3
Step-by-step explanation:
-5=-3x-33
-5+33=-3x
28=-3x
3x=-28
x=28/3
x=9 1/3
Answer: X=-28/3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−5=−3(x+11)
−5=(−3)(x)+(−3)(11)(Distribute)
−5=−3x+−33
−5=−3x−33
Step 2: Flip the equation.
−3x−33=−5
Step 3: Add 33 to both sides.
−3x−33+33=−5+33
−3x=28
Step 4: Divide both sides by -3.
-3x/-3= 28/-3
X=-28/3

Answer:
Yes, this set of lengths can form a triangle.
Step-by-step explanation:

Answer:
Step-by-step explanation:
2k = 18
divide by 2 on both sides
k = 9
Answer:
a. 2k=18
b. k=9
Step-by-step explanation:
a. The image shows that the weight of two k's equals 18. You can write that as k+k=18. In that equation there are two k's so 2 becomes the coefficient of k, making the equation 2k=18
b. To figure out what k equals you need to do the inverse operation. 2k means 2×k, so the inverse operation would be to divide 18 by 2. To check the answer plug 9 back in as k. 2×9=18
Carmen reads 2/3 chapters in 7/8 hours. What is the unit rate in chapters per hour?
Write your answer in simplest form.
Answer:
16/21
Step-by-step explanation:
Divide both sides by 7 to get 1/8
2/3 = 7/8
1/7 x 2/3 = 7/8 x 1/7
2/21 = 1/8
Then multiply both sides by 8 to get 8/8 which is 1
8/1 x 2/21 = 1/8 x 8/1
16/21 = 1
Select the correct answer. 7 2 2 4 Which of the following inequalities is graphed on the coordinate plane? O A y > 2r + 2 B. Y 2r + 2 Oc. y < 2.r + 2 OD. y < 2x + 2 PLEASE I NEED HELP
Answer:
The inequality that graphed is y ≥ 2x + 2 ⇒ B
Step-by-step explanation:
The form of the linear equation is y = m x + b, where
m is the slope of the lineb is the y-interceptIn the given figure
∵ The equation of the line is y = m x + b
∵ The line intersects the y-axis at the point (0, 2)
∴ b = 2
→ Use the rule of the slope m = [tex]\frac{y2-y1}{x2-x1}[/tex] to find m
∵ The line passes through points (-1, 0) and (0, 2)
∴ x1 = -1 and y1 = 0
∴ x2 = 0 and y2 = 2
→ Substitute them in the rule above
∴ m = [tex]\frac{2-0}{0--1}[/tex] = [tex]\frac{2}{0+1}[/tex] = 2
→ Substitute the values of m and b in the equation above
∴ The equation of the line is y = 2x + 2
∵ The line is solid
∵ The shaded area is over the line
∴ The sign of inequality is ≥
∴ The inequality is y ≥ 2x + 2
∴ The inequality that graphed is y ≥ 2x + 2

Have a terrib- nice day
what is m N
sydyfhhd
Answer:
68
Step-by-step explanation:
In this case, angle P and angle M are equal to each other. So we can set up the equation like this:
4x+36=6x-2
Then we can start to simplify and match up like terms:
2+36=6x-4x
Then add or subtract the like terms:
38=2x
Then, divide both sides by 2:
x=19
So we can insert 19 for x for both expressions:
Angle P: 112
Angle M: 112
So since every quadrilateral adds up to 360, we can subtract 2(112) from 360:
360-2(112)
360-224
=136
Since angle Q and N should be equal, we can divide 136 by 2 to get the measure for angle N and angle Q:
136/2=68
So the measure of angle N is 68
