Which are steps in the process of completing the square used to solve the equation 3 – 4x = 5x2 – 14x? Check all that apply.
3 = 5(x2 + 2x)
3 = 5x2 – 10x
4 = 5(x2 – 2x + 1)
8 = 5(x2 – 2x + 1)
3 = 5(x – 1)2
4 = 5(x – 1)2
StartFraction 8 Over 5 EndFraction = (x – 1)2
Answer:
1. 3 = 5x2 – 10x
2. 8 = 5(x2 – 2x + 1)
3. StartFraction 8 Over 5 EndFraction = (x – 1)2
Step-by-step explanation:
3-4x=5x^2-14x
3=5x^2-14x+4x
3=5x^2-10x
5x^2-10x-3=0
1. 3 = 5x2 – 10x
2. 8 = 5(x2 – 2x + 1)
8=5x^2-10x+5
8-5=5x^2-10x
3=5x^2-10x
3. StartFraction 8 Over 5 EndFraction = (x – 1)2
8/5=x^2-2x+1
Cross product
8=5(x^2-2x+1)
8=5x^2-10x+5
8-5=5x^2-10x
3=5x^2-10x
Answer:
3 - 4x = 5x2 - 14x
= 3 - 5x2 = - 14x + 4x
= 3 - 10 = 10x
= 7 = 10x
= x = 7/10
= x = 0.7

Answer:
Hi! The answer to your question is the range is 23
Step-by-step explanation:
Subtract the minimum data value from the maximum data value to find the data range. In this case, the data range is 62-39=23
VOCAB:
Minumum Data = Smallest Number
Maximum Data = Largest Number
Data Range = The set of y-values that a function passes through, Also the right coordinate in a coordinate pair.
In statistics, the difference between the largest number and the smallest numbers in a data set.

a shipement of 14 microwave ovens contains six defective units A vending company has ordered 4 of these units and selection will be random, what is the probability that all 4 units are good
Answer:
The probability that all 4 units are good is 10.66%.
Step-by-step explanation:
Given that a shipement of 14 microwave ovens contains six defective units, and a vending company has ordered 4 of these units and selection will be random, to determine what is the probability that all 4 units are good the following calculation must be performed:
14 - 6 = 8
8/14 x 8/14 x 8/14 x 8/14 = X
0.5714 x 0.5714 x 0.5714 x 0.5714 = X
0.1066 = X
0.1066 x 100 = 10.66
Therefore, the probability that all 4 units are good is 10.66%.

Find the input (x) of the function y = 1/4x+ 12 if the output
(y) is 6
Answer:
x = -24
Step-by-step explanation:
y = 1/4x+12 (Substitute 6 for y)
6 = 1/4x+12 (Subtract 12 from both sides)
6-12= -6 so its now -6 = 1/4x and since its a fraction you want to multiply both sides by the reciprocal
4*-6 = 1/4x*4 (1/4*4=1 which is 1x or x)
-24 = x
Answer:
y=1/4x+12
6=1/4x+12
1/4x=6-12
1/4x=-6
0.25x=-6
x=-6÷0.25
x=-24

Building A is 490 feet tall and Building B is 754 feet tall. If the angle of depression from the top of Building B to the top of Building A is 46°, how far apart are the buildings?
Answer: [tex]254.94\ ft[/tex]
Step-by-step explanation:
Given
Building A is 490 feet tall and building B is 754 ft tall.
If the angle of depression from building B to the top of building A is [tex]46^{\circ}[/tex]
Difference in the height of the two buildings is [tex]754-490=264\ ft[/tex]
If the difference between them is [tex]x[/tex]
From the figure, we can write
[tex]\Rightarrow \tan 46^{\circ}=\dfrac{264}{x}\\\\\Rightarrow x=\dfrac{264}{\tan 46^{\circ}}\\\\\Rightarrow x=254.94\ ft[/tex]
Therefore, the two buildings are [tex]254.94\ ft[/tex] apart.

You pay $3 per square foot for carpeting. Which equation can be solved to find the
amount you will pay to cover a triangular section of the floor with a base of 2 yards and
a height of 5 yards?
Answer:
3 * (½*2*5) = x
Step-by-step explanation:
Cost of carpeting = $3 per square foot
We have a triangular section to cover having the following dimensions:
base = 2 yd
height = 5 yd
First, let's find the area of the section = area of triangle
Area of triangle = ½*base*height
Area of the triangular section of the floor = ½*2*5
If $3 will cover 1 ft², therefore,
x will cover ½*2*5
Thus:
3 * (½*2*5) = x

Stephen is merging onto a highway. The increase in Stephen's speed for the first 8 seconds can be described by the function f(t)=t2+13t, where t is time in seconds. Which is the average rate of change of f(t) between t=2 and t=6?
Answer:
21m/s
Step-by-step explanation:
The average rate of change is expressed as;
A(t) = f(b) - f(a)/b-a
a = 2, b = 6
f(2) = 2² + 13(2)
f(2) = 4 + 26
f(2) = 30
f(6) = 6² + 13(6)
f(6) = 36 + 78
f(6)= 114
b- a = 6-2
b-a = 4
Substitute;
A(t) = 114 - 30/4
A(t) = 84/4
A(t) = 21
Hence the average rateof change is 21m/s

i want to fined out the digree of polynomial 5 x^4 + 3 x^2 + 1
Answer:
4
Step-by-step explanation:
The degree of a polynomial is the highest degree of a monomial contained within the polynomial. The degree of the monomial is the sum of the exponents on the variables. Example, the degree of -4x^6y is 6+1=7.
Example, the degree of 4x^8 is 8.
So the degree of 5x^4 is 4.
The degree of 3x^2 is 2.
The degree of 1 is 0 since there is no variable in this expression.
So the degree of 5 x^4 + 3 x^2 + 1 is 4.
