Can someone please help to differentiate this?
Answers
Answer:
[tex]\frac{dy}{dx} = (x+3)^{4} (7)(x-5)^{6} + (x-5)^{7} (4)(x+3)^{3}[/tex]
The values of x are x = -3 ,5 and [tex]x = \frac{-1}{11}[/tex]
Step-by-step explanation:
Step(i):-
Given that the function
y = (x+3)⁴(x-5)⁷ ...(i)
Apply UV formula
[tex]\frac{dy}{dx} = U^{l} V+ U V^{l}[/tex]
Differentiating equation (i) with respective to 'x ', we get
[tex]\frac{dy}{dx} = (x+3)^{4} (7)(x-5)^{6} + (x-5)^{7} (4)(x+3)^{3}[/tex]
Step(ii):-
Given that
[tex]\frac{dy}{dx} = 0[/tex]
[tex](x+3)^{4} (7)(x-5)^{6} + (x-5)^{7} (4)(x+3)^{3} =0[/tex]
[tex](x+3)^{3}(x-5)^{6} (7(x+3)+4(x-5))[/tex] =0
[tex](x+3)^{3}(x-5)^{6} =0 and (7(x+3)+4(x-5)) =0[/tex]
x = -3 and x=5 and 7x +21 +4x -20 =0
x = -3 and x=5 and [tex]x = \frac{-1}{11}[/tex]

A save percentage in lacrosse is found by dividing the number of saves by the number of shots faced. A lacrosse goalie saved 9 of 12 shots. How many additional consecutive saves must the goalie make to raise his percentage to 0.850?
Answers
he would have to take 8 more shots.
Step-by-step explanation:
9saves divided by 12 shots = .75
if you keep adding a shot and a save each time, you get to 17saves divided by 20shots=.85.
Hope this helps!
The percentage can be determined by multiplying the fraction to 100. In order to raise his save percentage to 0.850 goalie has to make one additional save.
Given that,
The number of shots saved out of 12 = 9.
Save percentage = (number of saves ÷ number of shots faced)
In the given case save percentage is as below,
= 9 ÷ 12
= 0.75
Suppose the number of saves to increase the save percentage to 0.85 be N.
Then as per the question,
0.85 = N ÷ 12
=> N = 12 × 0.85
=> N = 10
Thus, the number of additional saves is given by 10 - 9 = 1.
Hence, goalie must make one additional save to raise his percentage to 0.850.

If k is the midpoint of, jk=11x-7 and kl=6x+2, find jl
Answers
Answer:
JL = 118/5
Step-by-step explanation:
Because K is the midpoint, we know that JK and KL are going to equal each other because of the Segment Addition Postulate.
JK + KL = JL
So we know that JK = 11x-7 and KL = 6x+2
Now, we solve for X.
11x-7 = 6x+2
In order to get X alone, we must get the X's all to one side and the numbers to one side.
11x-7 = 6x+2
+7 +7
11x = 6x + 9
-6x -6x
5x = 9
x = 9/5
Now, we plug X into the equations.
JK = 11x - 7
JK = 11(9/5) - 7
JK = 99/5 - 7
JK = 64/5
KL = 6x + 2
KL = 6(9/5) + 2
KL = 54/5
Now, we add the numbers (fractions, really) together so that we can get the whole value of the line.
64/5 + 54/5 = 118/5
1) A puppy eats a sausage 5 seconds faster than a kitten eats an identical sausage. If they share one sausage, they can eat it in 6 seconds. How long does it take each animal to eat a sausage alone?
2) A tourist ignores the warning signs and leaves food in his car while he goes for a hike. A mama bear and her cub open the car door in 6 seconds. How long would it take each bear to open the car door alone if the cub needs 9 more seconds than the mama bear?
3) A superhero and his sidekick simultaneously leave the city and fly toward a secret hideout that is 1800 km away. The superhero's speed is 100 km/h slower than the sidekick's speed, and so he arrives at the hideout 36 minutes after his sidekick. Find the speed of each.
4) A bear loves visiting his friend, the piglet. The distance between their houses is 300m, and the bear always walks from his house to the piglet's house in exactly the same amount of time. But today, the bear stops at a beehive after walking 1/4 of the distance. He eats honey for 2.5 minutes and then continues to the piglet's house at a speed 15 m/min faster than usual. The total journey to the piglet's house takes the exact same amount of time as it usually does, when the bear does not stop for honey. How long does the journey take?
Answers
Answer:
1) The puppy takes 10 minutes, the kitty takes 15 minutes.
2) The mama bear takes 9 minutes, the cub takes 18 minutes
3) The sidekick goes at 600 mph, the hero goes at 500 mph.
4) 10 Minutes
5) RSM is so hard, amiright?
Step-by-step explanation:
1) You can simplify the word problem into the equation 1/x + 1/x+5 = 1/6. For problems like these, you have to simplify the last part to a fraction, not a whole number. Then you just solve.
2) Same thing. 1/x + 1/x+9 = 1/6. Solve. Boom. Done.
3) A bit different, but it simplifies to 1800/x-100 - 1800/x = .6. Solve. C'mon, you should've been able to do this one.
4) Harder, simplifies to 75/x+225/x+15+2.5 = 300/x. You get the last part because the time the bear took is equal to the time it would normally take, which is the entire distance over the normal pace. Then you solve and there we go, most of your RSM homework is done.

Step-by-step explanation:
They're never going to be the same because Bob's Gym starts at a higher number and also increases by a larger number
Answer:
-20 months lol
Step-by-step explanation:
so the first step to this is to create and equation for each
for guys gym the equation would be 5x+100 and for bob's gym the equation would be 8x+160
because we want them to equal each other we write the equation
5x+100=8x+160 and solve for x to see how many months it will take for the gyms to charge the same amount
step 1 subtract 100 from each side
5x=8x+60
step 2 subtract 8 from each side
-3x=60
step 3 divide each side by -3
x=-20 it will take -20 week for them to charge the same amount

= (Total boxes - sold boxes) × number of chocolates in each box
= (295 - 67) × 24
= 228 × 24
= 5,472 chocolates
hence, the number of chocolates remains unsold is 5,472

After swimming 60 feet below the surface of water, a whale swims up 30 feet. Use a number line to help you create an equation that shows the new location of the whale in relation to the water service.
A. The equation is -60 + (-30) = -90. The whale is 90 feet below the waters surface.
B. The equation is -60 + (-30) = -30. The whale is 30 feet below the water surface.
C. The equation is -60 + 30 = -30. The whale is 30 feet below the water surface.
D. The equation is -60 + 30 = -90. The whale is 90 feet below the water surface.
Answers
Answer:
C. The equation is -60 + 30 = -30. The whale is 30 feet below the water surface
Step-by-step explanation:
At the surface of the water in the swimming pool, the height of elevation is 0.
Thus, if you swim 60 ft below the surface, it means you are going in the negative direction when we consider a number line. Thus, distance = -60 ft
Now, when you swim back up by 30 ft, it is in the positive direction. Thus, total distance is now; -60 + 30 = -30 ft
Thus value denotes a negative direction and it means you are 30 ft below the surface of the water.
