Read this sentence in the problem carefully.
"<span>The number of pages in each program is determined by the number of graduates."

That means that you can have any number of graduates, and you will figure out the number of pages in the program depending on the number of graduates.

g, the number of graduates, is the independent independent variable.
p, the number of pages, is the dependent variable.

Solve the equation for the unknown variable.

Georgia [21]

Answer:

d = -3

Step-by-step explanation:

Given the equation:

$d^3 = -27$

Solve for d:

Take both sides cube root we have;

$d =\sqrt[3]{-27}$

We can write 27 as:

$27 = 3 \cdot 3 \cdot 3 = 3^3$

then;

$d = \sqrt[3]{-3^3}$

Using the rules:

$\sqrt[n]{a^n} = a$

$\sqrt[3]{-1} = -1$

then;

$d = -\sqrt[3]{3^3} = -3$

therefore, the unknown variable d is, -3

Solve and round to the nearest hundredth please!!!

sasho [114]

Answer:

x = 0.96

Step-by-step explanation:

$7 \times 16^{8x - 8} = 3$

$(2^4)^8(x - 1) = \dfrac{3}{7}$

$2^{32(x - 1)} = \dfrac{3}{7}$

$\log 2^{32(x - 1)} = \log \dfrac{3}{7}$

$32(x - 1)\log 2 = \log 3 - \log 7$

$(x - 1) = \dfrac{\log 3 - \log 7}{32}$

$(x - 1) = \dfrac{\log 3 - \log 7}{32\log 2}$

$x = \dfrac{\log 3 - \log 7}{32\log 2} + 1$

$x = 0.961800237...$
