When the function f(x) is divided by 4x−5, the quotient is 3x^2 −x+3 and the remainder is −2. Find the function f(x) and write the result in standard form.
Answer:
Step-by-step explanation:
f(x) = (4x-5)(3x²-x+3) - 2
= (12x³-4x²+12x)-(15x²-5x+15) -2
= 12x³ - 19x² + 17x - 17
Adrian purchased a new car in 1990 for $24,900. The value of the car has
been depreciating exponentially at a constant rate. If the value of the car was
$13,500 in the year 1994, then what would be the predicted value of the car
in the year 1999, to the nearest dollar?
Answer:
Multiply it by 4 and divide it by 100. It should be1,100. Now multiply it by12. it should be 13200 . Now subtract that to the original price. 14300

6. You're gonna use Cos to find Y
Cos = adj/hyp
Cos 27 = 10/y
10/cos27 = y
11.2 = y
7. It'll help immensily if you draw this one out.
You're gonna use Sin to find the angle.
Sin = opp/hyp
Sin 65 = 14/x
14/sin65 = x
15.4 = x

A convenience store sells two brands of orange juice. Brand A contains 8 fluid ounces and costs $1.28. Brand B contains 12 fluid ounces and costs $1.68. What is the difference in cost, in dollars, per fluid ounce between the two brands?
Answer:
$0.02
Step-by-step explanation:
Brand a
1.28 ÷ 8 = 0.16 per ounce
Brand b
1.68 ÷ 12 = 0.14 per ounce
0.16 - 0.14 = 0.02
The length of two sides of a right triangle are leg:
10 m and hypotenuse: 15 m.
Find the length of the third side.
Answer:
11.2m
Step-by-step explanation:
Using Pythagoras,
a²+b²=c²
10²+b²=15²
100+b²=225
b²=225-100
b²=125
b=√125
b=11.2m

One of the students is chosn at random. What is the probability of picking a student who sciored above 65
Answer: 7 / 18
Step-by-step explanation:
There were 18 students.
Out of them, the scores above 65 are:
73, 73, 69, 68, 71, 76, 70
There are 7 of them.
Probability of picking someone who scored higher than 65 is:
= Number of people who scored above 65/ Total number who took the test
= 7 / 18

Does association between variables mean that there is a cause-and-effect
relationship? Why or why not? Give an example.
Answer:
Yes
Step-by-step explanation:
Two variables may be associated without a causal relationship. For example, there is a statistical association between the number of people who drowned by falling into a pool and the number of films Nicolas Cage appeared in in a given year. However, there is obviously no causal relationship.

CB = - AD = - 3y
How can I factorise expressions
Answer:
The first step of factorising an expression is to 'take out' any common factors which the terms have. So if you were asked to factorise x² + x, since x goes into both terms, you would write x(x + 1) . This video shows you how to solve a quadratic equation by factoring.

Answer:
f(x) = -2(x-3)^2+8
Step-by-step explanation:
Using vertex form: f(x)= a(x-h)^2 +k
if the maximum is 8 then k=8
h = 3 --> the midpoint of 1 and 5
Fill in the equation:
f(x) = a(x-3)^2 +8
Using f(1) = 0 to figure out a:
0 = a(1-3)^2+8
4a =-8
a = -2
Our final equation would be[tex]f(x)=-2(x-3)^2+8[/tex]
In standard form: [tex]f(x)=-2x+12x-10[/tex]

Lisa is going on a 3 3/4 mile hike. She has already hiked 1 1/4 miles. How many more miles does she have left to hike?
Answer:
C = 2½ miles.
Step-by-step explanation:
Let the total distance be A
Let the distance covered be B.
Let the unknown distance (distance left) be C.
Given the following data;
A = 3¾ miles
B = 1¼ miles
To find the distance left to hike;
A = B + C
Substituting into the equation, we have;
3¾ = 1¼ + C
C = 3¾ - 1¼
C = (3 - 1) ¾ - ¼
C = 2 2/4
C = 2½ miles.
Method II.
We would convert the mixed fraction into a proper fraction:
A = 3¾ = (4*3 + 3)/4 = 15/4
B = 1¼ = (4*1 + 1)/4 = 5/4
C = 15/4 - 5/4
C = 10/4
C = 5/2
C = 2½ miles.
