2. Factors of x^2 - 5x + 6 are (x-2)(x-3) so the answer would be 2) (x-2)
4. Factors of x^2 + x - 20.  First find the factors of 20.  1, 20; 2, 10, 4, 5.  Then find which factors would equal "b" in the equation or in this instance "1".  This would be 4 & 5.  Since "c" is a negative 20, one of the factors will be a negative.  So, the factors of this trinomial are (x-4)(x+5).  
6.  Factors of n^2 + 3n - 54.  First find the factors of 54.  1, 54; 2, 27; 3, 18; 6, 9.  Then find which of these factors would equal 3.  This would be 6, 9.  Since 54 is negative, and 3 is positive, the larger of the two factors will be the positive # and the smaller will be the negative #.  So, the factors of this trinomial are (x-6)(x+9).

Answer:

The forth box for c will be 22

Step-by-step explanation:

If c = 10 , b = 5

If c = 14 , b = 7

If c = 18 , b = 9

If c = 22 , b = 11

If c = 26 , b = 13

A container has 130 gallons of water and is being filled at a rate of 1/4 gallon each second. Another container has 200 gallons
jasenka [17]

Answer:

120 seconds

Step-by-step explanation:

To solve this question you have to make equation of both gallon.

Gallon 1 have 130 gallons of water at the start and filled by 1/4 gallon each second. If x equal to the time in seconds, the equation of gallon 1 volume will be:

g1= 130+ 1/4x

Gallon 1 have 200 gallons of water at the start and drained by 1/ 3  gallon each second,  the equation of gallon 2 volume  :  

g2= 200- 1/3x

When gallon 1 volume equal to gallon 2, it mean g1=g2

g1= g2

130+ 1/4x  =  200- 1/3x  

130- 200= -1/3x -1/4x

-70= - 4/12x - 3/12x

-7/12x= -70

7/12x= 70

x= 70*12/7

x= 120

Find a formula for the exponential function passing through the points (-1,5/3) and (3, 135).
Artyom0805 [142]

The expression y = 4.998 · e^{1.098\cdot x} is the exponential function that passes through the points (- 1, 5 / 3) and (3, 135).

<h3>How to derive an exponential function that passes through two given points</h3>

Herein we find the location of two points set on Cartesian plane that belongs to an exponential function of the form:

y = A \cdot e^{B \cdot x}

Where:

  • A - y-Intercept of the exponential function.
  • B - Growth factor
  • x - Independent variable.
  • y - Dependent variable.

Which is equivalent to the following logarithmic expression:

㏑ y = ㏑ A + B · x

If we know that (x₁, y₁) = (- 1, 5 / 3) and (x₂, y₂) = (3, 135), then the following system of equations is generated:

㏑ (5 / 3) = ㏑ A - B

㏑ 135 = ln A + 3 · B

Then, we solve the system by numerical methods:

㏑ A = 1.609 (A = 4.998), B = 1.098

And the exponential function is equal to y = 4.998 · e^{1.098\cdot x}.

The ratio of petunias to geraniums in the greenhouse was 15 to 2. Combined there was 1020. How many geraniums were in the greenh
Mrac [35]

in short, we simply split the total amount by the given ratio, so we'll split or divide 1020 by (15 + 2) and then distribute accordingly.

\bf \cfrac{petunias}{geraniums}\qquad 15:2\qquad \cfrac{15}{2}~\hspace{7em}\cfrac{15\cdot \frac{1020}{15+2}}{2\cdot \frac{1020}{15+2}}\implies \cfrac{15\cdot \frac{1020}{17}}{2\cdot \frac{1020}{17}} \\\\\\ \cfrac{15\cdot 60}{2\cdot 60}\implies \cfrac{900}{120}\implies \stackrel{petunias}{900}~~:~~\stackrel{geraniums}{120}
