The product of two consecutive positive integers is 1,332. Explain how you can write and solve a quadratic equation to find the value of the larger integer.
x - the larger integer (x>0)
x-1 - the smaller integer (the difference between two consecutive integers is always 1)
The product of two consecutive positive integers is 1,332
so:
x•(x -1 ) = 1332
x² - x = 1332
x² - x - 1332 = 0 ⇒ a = 1, b = -1, c = -1332
[tex]x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}=\dfrac{-(-1)\pm\sqrt{1^2-4\cdot1\cdot(-1332)}}{2\cdot1}=\dfrac{1\pm\sqrt{1+5328}}{2}\\\\\\x_1=\dfrac{1+\sqrt{5329}}{2}=\dfrac{1+73}{2}=37\\\\x_2=\dfrac{1-\sqrt{5329}}{2}\ \not>\ 0[/tex]
x = 37
Answer:
The numbers can be written as x and x + 1. Set the product of the numbers equal to 1,332 to get x(x + 1) = 1,332. You can solve the quadratic equation by using the quadratic formula, completing the square, or factoring. When you solve the quadratic equation, you find that x = –37 and 36. Since the question asked for positive integers, the only viable solution is x = 36. To solve for the larger integer, you add 1 to 36 to get an answer of 37.

Answer:
Price(P) = $200
Maximum charge = 200
Step-by-step explanation:
Given:
Sales = 600 - 3p
Number of customer = 0
Find:
Price(P)
So,
600 - 3p = 0
3p = 600
Price(P) = $200
Revenue = [600 - 3p]p
600p - 3p²
Maximum charge = 200

Step-by-step explanation:
Answer:
A correctly displays the number.
Step-by-step explanation:
A railway system on a hillside moves passengers at a constant rate to an elevation of 50 m. The elevations of a train are given for 2 different
locations.
a. Write an equation in point-slope form to represent the elevation of the train in terms of time. How can the equation be used to find the rate
of increase in elevation of the train in meters per second?
b. At what elevation does the train start initially? Write a linear equation in a form that gives the information as part of the equation. Explain
your reasoning
a. If x is the time in seconds and y is the elevation of the train in meters, then represents the elevation of the train in terms of time.
(Type an equation. Type your answer in point-slope form. Use integers or decimals for any numbers in the equation.)
Answer:
part a) y
-9=0.4(x-14.5)
part b) slope= 0.4
part c) 3.2 meters
final answer is y=0.4x+3.2( slope-intercept )
Step-by-step explanation:
hope that help :)
The equation of the model given written in point slope form is :
y - 9 = 0.4(x - 14.5)Velocity on meter per second = 0.4 m/s Initial elevation = 3.2 mFinal elevation = 50 m
Using the information given :
9 meter = 14.5 seconds - - - - (1)
20 meter = 42 seconds - - - - (2)
(20 - 9)meters = (42 - 14.5) seconds
11 meters = 27.5 seconds
Speed = distance / timeSpeed = 11 / 27.5
Speed = 0.4 meters per second
The equation in point slope form can be represented thus :
The initial velocity :
At y = 9 meters ; x = 14.5 seconds ; c = initial elevation
y = 0.4x + c
9 = 0.4(14.5) + c
9 = 5.8 + c
c = 9 - 5.8
c = 3.2 m
In point - slope form, the equation can be written as :
Therefore, the equation of the model written in point - slope form is : y - 9 = 0.4(x - 14.5)

A car can travel 400 miles on a full tank of petrol. A more efficient car can travel 30% further. How many miles further can it travel on a tank? *
5 points
Answer:160 miles
Explanation:
You can work out this type of question by using the 'unitary' method, which means finding out how much for ONE.
If you set out the steps with short sentences it will be clearer.
On 15 gallons, a car can travel 400 miles÷15↓
On 1 gallon, a car can travel 400÷15=262
miles
Once you know the distance travelled on 1 gallon of fuel, you can work out the distance travelled for any number of gallons.

Answer:
2^-3Step-by-step explanation:
Solving in steps
Using exponent rules: a^b·a^c = a^(b+c) and (a^b)^c = a^(bc)
4^−6 ⋅ 4^4⋅ (2^3⋅ 2^−4)^−1 = 4^(-6 + 4) ⋅ (2^(3 - 4))^-1 =4^-2 ⋅ (2^(-1))^-1 =(2^2)^-2 ⋅ 2^((-1) ⋅ (-1)) =2^-4 ⋅ 2^1 = 2^(-4 + 1) =2^-3Answer:
2 ⁻³Step-by-step explanation:
the expression 4^−6⋅ 4^4⋅ (2^3⋅ 2^−4)^−1 can be solved using exponential rule:
= 4⁻⁶ * 4⁴ * (2³ * 2⁻⁴)⁻¹
= 4⁽⁻⁶ ⁺ ⁴⁾ * (2 ⁽³ ⁻ ⁴⁾ ) ⁻¹
= 4⁻² * (2⁻¹)⁻¹
= (2²) ⁻² * 2 ⁽⁻¹ ˣ ⁻¹⁾
= 2⁻⁴ * 2¹
= 2 ⁽⁻⁴ ⁺ ¹⁾
= 2 ⁻³
(a) The perimeter of a rectangular field is 372 m.
If the width of the field is 87 m, what is its length?
Answer:
98 m
Step-by-step explanation:
Answer:
The length of the field is 99 m.
Step-by-step explanation:
First, multiply 87 by 2 to get 174. Then, subtract 174 (total of the two width sides) from 372 (total perimiter) to get 198. Lastly, divide 198 by 2, because 198 is the total of the 2 length sides, and you will get 99 m per length side.

#17, #18, #19
Answer:
they all equal 105°
Step-by-step explanation:
Answer:
∠ 2 = ∠ 5 = ∠ 7 = 105°
Step-by-step explanation:
∠ 2 and ∠ 3 are same- side interior angles and are supplementary, thus
∠ 2 = 180° - ∠ 3 = 180° - 75° = 105°
∠ 5 and ∠ 2 are vertical angles and congruent, thus
∠ 5 = 105°
∠ 2 and ∠ 7 are alternate angles and congruent, thus
∠ 7 = 105°

5.6 + 2.2x > 65.6 - 1.8x
Answer:
x > 15
Step-by-step explanation:
5.6 + 2.2x > 65.6 - 1.8x
Add 1.8x to each side
5.6 + 2.2x+1.8x > 65.6 - 1.8x+1.8x
5.6 + 4x > 65.6
Subtract 5.6 from each side
5.6 + 4x -5.6 > 65.6 - 5.6
4x > 60
Divide each side by 4
4x/4 > 60/4
x > 15
Answer:
15
Step-by-step explanation:
5.6 + 2.2x > 65.6 - 1.8x
Add 1.8x to each side
5.6 + 2.2x+1.8x > 65.6 - 1.8x+1.8x
5.6 + 4x > 65.6
Subtract 5.6 from each side
5.6 + 4x -5.6 > 65.6 - 5.6
4x > 60
Divide each side by 4
4x/4 > 60/4
x > 15
