Step-by-step explanation:
Review the proof of cos(A - B) = cosAcosB + sinAsinB.
Which of the following complete step 4 of the proof?
1 and 1
2 and 1
(cosAcosB)2(sinAsinB)2 and (cos2(A – B))((sin2(A – B))
(cos2A + sin2A)(cos2B + sin2B) and (cos2(A – B))(sin2(A – B))
Answer:
Option (2)
Step-by-step explanation:
Step 1.
[tex]\sqrt{(\text{cosA-cosB})^2+(\text{sinA-sinB})^2}=\sqrt{(cos(A-B)-1)^2+(sin(A-B)-0)^2}[/tex]
Step 2.
(cosA - cosB)² + (sinA - sinB)² = [cos(A - B) - 1]² + [sin(A - B) - 0]²
Step 3.
cos²A + cos²B - 2cosAcosB + sin²A + sin²B - 2sinAsinB = cos²(A - B) + 1 - 2cos(A - B) + sin²(A - B)
Step 4.
2 - 2cosAcosB - 2sinAsinB = 1 - 2cos(A - B) + 1
Step 5.
cosAcosB + sinAsinB = cos(A - B)
Therefore, Option (2) will be the answer.
Answer:
the answer is 2 and 1 or B
Step-by-step explanation:
En cierto cultivo, inicialmente había 1000 amebas que se reproducen por biparticion cada día ¿Cuántas amebas habrá al cabo de 30 días después que se inició el cultivo ?
Answer: 1,073,741,824,000 amebas
Step-by-step explanation:
Bipartición significa que la población de amebas se duplica cada día.
Entonces si inicialmente hay 1000, después de un día van a haber:
2*1000.
Después del segundo día se vuelven a duplicar, entonces van a haber:
2*(2*1000) = (2^2)*1000
Después del tercer día, lo mismo:
2*(2^2)*1000 = (2^3)*1000.
A esta altura ya se puede ver el patrón, podemos concluir que después de N días, la población de amebas va a ser:
P(N) = (2^N)*1000.
Entonces respondiendo a la pregunta:
¿Cuántas amebas habrá al cabo de 30 días después que se inició el cultivo?
Tenemos que tomar N = 30
P(30) = (2^30)*1000 = 1,073,741,824,000 amebas

Answer:
[tex]\boxed {x = -2}[/tex]
Step-by-step explanation:
Solve for the value of [tex]x[/tex]:
[tex]3x + 6 = -3(2x + 4)[/tex]
-Use Distributive Property:
[tex]3x + 6 = -3(2x + 4)[/tex]
[tex]3x + 6 = -6x - 12[/tex]
-Take [tex]6x[/tex] and add it to [tex]3x[/tex]:
[tex]3x + 6 + 6x = -6x + 6x - 12[/tex]
[tex]9x + 6 = -12[/tex]
-Subtract both sides by [tex]6[/tex]:
[tex]9x + 6 - 6 = -12 - 6[/tex]
[tex]9x = -18[/tex]
-Divide both sides by [tex]9[/tex]:
[tex]\frac{9x}{9} = \frac{-18}{9}[/tex]
[tex]\boxed {x = -2}[/tex]
Therefore, the value of [tex]x[/tex] is [tex]-2[/tex].

A bicycle has a listed price of 777.99 before tax. If the sales tax rate is 8.5% , find the total cost of the bicycle with sales tax included.
Round your answer to the nearest cent, as necessary.
Answer:
$844.12
Step-by-step explanation:
8.5% of $777.99 is equal to $66.12915. When it is added to the original price, it equals $844.11915. When you round it up to the nearest cent or hundredth, you get $844.12

Which of the following slopes would make the "steepest" line?
A.
1/2
B.
3/2
C.
3
D.
4/5
Answer:
D 4/5
Step-by-step explanation:
Answer:
c
Step-by-step explanation:
try giving all of the fractions the same denominator. then, whichever has the biggest numerator is the steepest slope!
the number that 5, 2, and 1 all have in common is 10, so for this question, we'll put all of the fractions over 10.
a. 1/2 = 5/10
b. 3/2 = 15/10
c. 3 = 3/1 = 30/10
d. 4/5 = 8/10
30 is the biggest numerator out of these 4.
Jessica wants to go on a school trip next month. The trip will cost $100 and she already has $10 and plans to babysit for $5 an hour to earn the rest of the money.
A. Write an equation that could be used to determine h, the number of hours Jessica needs to babysit to earn $100.
B. From your equation, determine the number of hours she needs to babysit.
Answer:
Step-by-step explanation:
100=10+5x x is the hours she needs to babysit
90=5x
x=18
She needs to babysit for 18 hours at $5 an hour if she already has $10
A 2-yard piece of string costs 1.50$. What is the price per foot?
PLEASE HELP
WILL MARK BRAINLIEST
Answer:
0.013333333333333
Step-by-step explanation:
short answer would be 0.013 i think lol
Hi! I believe your answer is $0.25 (twenty-five cents). There are 3 feet in a yard, so in 2 yards, there are 6 feet. If we want to know the cost per foot, we need to divide 1.50 by 6. The quotient is 0.25, or $0.25 per foot. I hope this helps you! Good luck and have a great day/night. ❤️✨

What is the domain of the decreasing function?
Answer:
A function f is called decreasing on an interval if f (a) > f (b) whenever a < b and a, b are in the interval.
Step-by-step explanation:
The domain of the function shown here is the interval [1, 6].On the interval [1, 3], the graph of this function gets higher from left to right; thus we say that this function is increasing on the interval [1, 3].
On the interval [3, 6], the graph of this function gets lower from left to right; thus we say that this function is decreasing on the interval [3, 6].
