For the typing purpose I replaced θ with n in the calculation
[tex]\lim_{n \to \frac{\pi }{4}} \frac{cos n-sin n}{\frac{\pi }{4} } ...limits L'Hopital's Rule\\= \lim_{n \to \frac{\pi }{4}} \frac{-sin n-cos n}{1 } ... plug. in . \frac{\pi }{4} \\= - sin \frac{\pi }{4} - cos \frac{\pi }{4}\\= - \frac{\sqrt{2} }{2} - \frac{\sqrt{2} }{2}\\= \frac{- 2\sqrt{2}}{2} \\= - \sqrt{2}[/tex]

Step-by-step explanation:
the area of a square is 400 units. if the length of each side of the square increased by one unit, would its area be a rational number
Answer:
Yes, the area of the square would be a rational number.
Step-by-step explanation:
Area of square = 400 units² = x²
x = one side length of square
x = √400 = 20 units
Increase each side length by 1 unit.
New side length = 21 units
Area of new square = 21² = 441
441 is a rational number because the square root of 400 is a rational number.
√400 = 21
Therefore: If the length of each side of the square increased by one unit, the area of the square would be a rational number. The area of the square would still be a perfect square.
Is each line parallel, perpendicular, or neither parallel nor perpendicular to the line 4x + 3y = 12? Drag and drop each choice into the boxes to correctly complete the table. Parallel Perpendicular Neither
Step-by-step explanation:
The line given:
4x + 3y = 12, its slope is m = - 4/3Other lines to compare:
-3x + 4y = 8, the slope is m = 3/4, it is perpendicular line as the product of the slopes is - 1;4x + 3y = 31, the slope is m = -4/3, same slope but different y- intercept, it is parallel line;3x + 4y = 12, the slope is m = -3/4, it is neither parallel nor perpendicular;-4x + 3y = - 1, the slope is m = 4/3, it is neither parallel nor perpendicularSlope=m=+4/3
#1
-3x+4y=8m=3/4
Perpendicular#2
4x-3y=31m=-4/3
Parallel#3
3x+4y=12m=-3/4
neither#4
-4x+3y=-1m=4/3
Neithery = 6(x – 3)2 + 4
How do I rewrite the quadratic function in standard form
Answer:
6x^2 -36x + 58
Step-by-step explanation:
expand (x-3)^2 = x^2 -6x +9
6(x-3)^2 +4=6(x^2 -6x +9) +4 =6x^2 -36x + 54 +4 = 6x^2 -36x + 58

9b-27= 3(2b-8)+2b solve for b
please show work on how you found b
Answer: b = 3
Step-by-step explanation:
9 − 27 = 3(2 − 8) + 2
9 − 27 = 6 − 24 + 2
9 − 27 = 6 − 24+ 2
9 − 27 = 8 − 24
9−27=8−24
9−27+27=8−24+27
9 = 8 + 3 ------Subtract 8b from both sides
b = 3

Answer:
Remember that the slope is the change in y/the change in x
Step-by-step explanation:
1. The slope [tex]\frac{-0.5- 0.5}{3 - (-3)}[/tex]
= [tex]\frac{-1}{6}[/tex]
2. Find "b" which is the y-intercept. Pick one of the two point and the slope.
Let use (-3, 0.5) and the slope is -1/6
y = mx + b
0.5 = -1/6 (-3) + b Solve for b
3 = 3 + b Multiply each term by 6
0 = B
3. Write the equation of the line y = mx + b
y = -1/6x + 0
In which situation would you most likely round numbers? (A) When you need to measure a precise amount of butter for cake recipe
(B) When you need to find out exactly how many guests are coming to your birthday party
(C) when you need to figure out about how much of a Carton of milk a box of cookies will cost together
(D) when you need to count the number of birthday cards and gifts you receive to be sure you didn’t lose any
Answer:
C
Step-by-step explanation:
its the only one that doesnt say precise or exactly or sure
Answer: C
Step-by-step explanation: when you need to figure out about how much of a Carton of milk a box of cookies will cost together. (You see it says "about" which means get it near the exact point. As for the others it uses words like "precise, exactly, etc".
Find the area use 3.14 for pi
Answer:
15.14 cm^2
Step-by-step explanation:
Area of rectangle = 4cm x 3 cm = 12cm^2
Radius of the circle = 2 cm
Area of 1/4 of a circle = (pi x r^2) / 4
= (3.14 x 4) / 4 = 3.14 cm^2
3.14 cm^2 + 12cm^2 = 15.14 cm^2

please help I dont understand
Answer:
3rd option
Step-by-step explanation:
A direct variation is expressed in this form:
y = kx
1. y - 4x = 8
y = 4x + 8 is not a direct variation
2. y + 2 = 7x
y = 7x - 2 is not a direct variation
3. y - 3x = 0
y = 3x is a direct variation
4. y = 5x - 2
y = 5x - 2 is not direct variation

Answer:
p = 35°
Step-by-step explanation:
Angles on a straight line add up to 180° so:
2p + 5 + 3p = 180° (simplify)
5p + 5 = 180° (subtract 5 from both sides)
5p = 175° (divide both sides by 5)
p = 35°
Hope this helps!
Answer:
p=35
Step-by-step explanation:
You have to add the two together and set them equal to 180, so 2p+5+3p=180 so 5p=175, so p=35.

Divide the total weight of dough by the amount required for 1 pizza
20 [tex]\frac{1}{4}[/tex] ÷ 1 [tex]\frac{1}{8}[/tex] ( change mixed numbers to improper fractions )
= [tex]\frac{81}{4}[/tex] ÷ [tex]\frac{9}{8}[/tex]
• leave first fraction , change ÷ to × , turn second fraction ' upside down '
= [tex]\frac{81}{4}[/tex] × [tex]\frac{8}{9}[/tex] ( cancel 81 and 9 by 9 )
= [tex]\frac{9}{4}[/tex] × 8 ( cancel 4 and 8 by 4 )
= 9 × 2
= 18 pizza's

Answer:
Common ratio is - 4 / 2.
Step-by-step explanation:
Sequence = - 2, 4, - 8, 16, - 32, ....
Let the terms be " a ".
Here,
a1 = 2
a2 = 4
a3 = - 8
a4 = 16
a5 = - 32
Let the common ratio be " r ".
r1 = a2 / a1
= 4 / - 2
r1 = - 2
r2 = a3 / a2
= - 8 / 4
r2 = - 2
r3 = a4 / a3
= 16 / - 8
r3 = - 2
r4 = a5 / q4
= - 32 / 16
r4 = - 2
Since, the common ratios are same,
Therefore, r = - 2
- 4 / 2 = - 2
So, - 2 can also be written as - 4 / 2.
Hence,
r = - 4 / 2
Finally,
Common ratio ( r ) = - 4 / 2
Solve.
