Answer:
20,000(x)^0.85 = 12,000
Step-by-step explanation:cd
if it "depreciates" over time, you take the value that it depreciates by and divide the full value of the car by that and get ^0.85, then, once you find the quotiont, you multiply that by the number of years it takes until you reach the goal. I have explained how to solve this problem, even gave the answer, but, I did not give the number of years, good luck! ;)
PEMDAS
multiply 2x2=4 and simplify the equation by looking for like terms to combine.
4+16x+y+34=0
4 and 34 are like terms so add them.
the simplified expression is 16x+y+38
<u>Answer:</u>
60 out of 250 children will prefer organized sports.
<u>Step-by-step explanation:</u>
We are given the results of a random survey of children between the ages of 13 and 18 about their favorite activity.
Based on these results, we are to find the number of children who will prefer organized sports if 250 children were asked about their favorite activity.
Children who will prefer organized sports = = 60
Step-by-step explanation:
slope formula when it's perpendicular : m1 × m = -1
Now Differentiate the quadratic function given.
d/dx ( x^2 - x + 1 ) at an x value of -1 from the point "(-1 , 3 )"
= 2x - 1 .... plug in the x value
= 2 × -1 - 1 = -3.
Use this equation...
y - y1 = m(x - x1)
m = slope = derivative at x = -1
y1 = value found by subbing -1 into the original function
x1 = the x value often given.
y - 3 = 1/3 (x + 1)
= 1/3x + 1/3 + 3
y = 1/3x + 10/3.
not sure about this one - it probably intersects at the x & y intercepts of the equation of the normal line.
y = 0 + 10/3 = 10/3
1/3x = 0 - 10/3
x = -10/3 / 1/3 = -10
so the point .... (-10 , 10/3)
<h3>Given</h3>
1 (female) pharmacist counting prescriptions at the end of the day
(prescriptions for antibiotics) = (7/4)×(prescriptions for tranquilizers)
33 = (prescriptions for tranquilizers) + (prescriptions for antibiotics)
<h3>Find</h3>
The number of (prescriptions for tranquilizers)
<h3>Solution</h3>
Let <em>x</em> represent the number of <em>prescriptions for tranquilizers</em>. Then the number of prescriptions for antibiotics is (7/4)x, and the total number of prescriptions is
... 33 = x + (7/4)x . . . . . . . . . . put the given information in the given relation
... 33 = (4/4)x + (7/4)x . . . . . . rewrite 1 as 4/4 so we can add to 7/4
... 33 = ((4+7)/4)x = (11/4)x . . . simplify
... 33×(4/11) = (4/11)×(11/4)x . . . multiply by the reciprocal of the coefficient of x
... 12 = x . . . . . . . . . . . . . . . . . simplify
The pharmacist had 12 prescriptions for tranquilizers.
The pharmacist had 33-12 = 21 prescriptions for antibiotics.
There was 1 pharmacist and 33 prescriptions.
