since \to :  x \sqrt[y]{ {n}^{z} }  = x( {n}^{ \frac{z}{y} } ) \\ then \: lets \: solve \: both \: values \: separately \to :  \\ \underline{ \boxed{solution \: to \:  \boxed{a}}} \\  120 \sqrt[3]{ {n}^{a} }  = 3 \sqrt{n} (40 \sqrt[6]{n} ) \\ 120 \sqrt[3]{ {n}^{a} }  = 3 \sqrt{n}  \times 40 \sqrt[6]{n} \\ 120 \sqrt[3]{ {n}^{a} }  = 120 (\sqrt{n} \times \sqrt[6]{n} ) \\ \sqrt[3]{ {n}^{a} }  = (\sqrt{n} \times \sqrt[6]{n} ) \\  {n}^{ \frac{a}{3} }  = {n}^{ \frac{1}{2} } \times {n}^{ \frac{1}{6} } \\ \frac{a}{3}  =  \frac{1}{2}   +   \frac{1}{6}  \\  \frac{a}{3}  =  \frac{4}{6}  \\ 6a = 12 \\ a =  \frac{12}{6}  =  2 \\ \underline{ \boxed{a  = 2 \:}}  \\  \\ \: \underline{ \boxed{solution \: to \:  \boxed{b}}} \\  27 \sqrt[4]{ {n}^{b} }  = 3 \sqrt{n} (9 \sqrt[4]{n} ) \\ 27 \sqrt[4]{ {n}^{b} }   = 3 \sqrt{n}  \times 9 \sqrt[4]{n} \\ 27 \sqrt[4]{ {n}^{b} }  = 27 (\sqrt{n} \times \sqrt[4]{n} ) \\ \sqrt[4]{ {n}^{b} }  = (\sqrt{n} \times \sqrt[4]{n} ) \\  {n}^{ \frac{b}{4} }  = {n}^{ \frac{1}{2} } \times {n}^{ \frac{1}{4} } \\ \frac{b}{4}  =  \frac{1}{2}   +   \frac{1}{4}  \\  \frac{b}{4}  =  \frac{3}{4}  \\ 4b = 12 \\ b =  \frac{12}{4}  =  3 \\ \underline{ \boxed{b  = 3 \:}}  \\ hence \to :  \\  \underline{ \underline{\boxed{a  = 2 \:}} \underline{ \boxed{b  = 3 \:}}}

Which of the following are solutions to the equation below (5x+1)^2=7?<br><br> Check all that apply.
stiv31 [10]
(5x+1)² = 7; expand: 25x² + 10x +1 = 7 or 25x² + 10x -6 = 0

Solve this quadratic for x:

x = [-b + √(b² - 4ac)]/2a and x = [-b - √(b² - 4ac)]/2a
Plug the values and you'll find :
x = (- √7 - 1)/5 (answer C)
x = (+√7 -1)/5  (answer E)

Write the equation in standard form. Identity the center and radius.<br> x² + y2 + 8x-4y-7=0
Masteriza [31]

Answer:

  • See below

Step-by-step explanation:

<u>Given equation:</u>

  • x² + y² + 8x - 4y - 7 = 0

<u>Convert this to standard form by completing the square:</u>

  • (x - h)² + (y - k)² = r², where (h, k) - center, r - radius
  • x² + 2*4x + 4² + y² - 2*2y + 2² - 16 - 4 - 7 = 0
  • (x + 4)² + (y - 2)² - 27 = 0
  • (x + 4)² + (y - 2)² = 27
  • (x + 4)² + (y - 2)² = (√27)²

The center is (- 4, 2) and the radius is √27

determine the base, b, of the exponential model. Is the base a growth or decay factor? a. b is 0.6394; It is a growth factor. b.
Kazeer [188]
An exponential model can be described by the function
f(x) = a(b)^x
where: a is the initial population or the starting number, b is the base and x is the number of periods elapsed.

When the base of an exponential model is greater than 1 it is called a growth factor, but when it is less than 1 it is called a decay factor.

Given the exponential model
n=20.5(0.6394)^t
n is the final output of the exponential model, 20.5 is the starting number, 0.6394 is the base and t is the number of periods/time elapsed.

Here, the base is 0.6394 which is less than 1, hence a decay factor.

Therefore, <span>the base, b, of the exponential model is 0.6394; It is a decay factor.</span>
