Inequality, because want to know when we'll make a profit.
$d (- 680+ 960) \geqslant 52000 \\ 280d \geqslant 52000$
Profit: Let's See When 280d equals 52000

$d \geqslant \frac{52000}{280} \\ d \geqslant 185.71$
So, after 190 days Julianne will make a profit
$280(190) \geqslant 52000 \\ 53200$

What is the logarithmic form of the solution to 102t = 9?

Harman [31]

Equivalent equations are equations that have the same value

The equation in logarithmic form is $t = \frac{\log(9)}{2}$

<h3>How to rewrite the equation</h3>

The expression is given as:

$10^{2t} = 9$

Take the logarithm of both sides

$\log(10^{2t}) = \log(9)$

Apply the power rule of logarithm

$2t\log(10) = \log(9)$

Divide both sides by log(10)

$2t = \frac{\log(9)}{\log(10)}$

Apply change of base rule

$2t = \log_{10}(9)$

Divide both sides by 2

$t = \frac{\log_{10}(9)}{2}$

Rewrite as:

$t = \frac{\log(9)}{2}$

Hence, the equation in logarithmic form is $t = \frac{\log(9)}{2}$

What’s the correct answer for this?

First, you'd work out the centre value

It would be the opposite value to what is in the brackets

Thus, the centre value is (2, -4)

Plot this value on a graph

In order to find the radius, you must square root the 25

Thus, the radius would be 5

Plot some points with a radius of 5 from the centre and then draw the circle

What is the degree of the polynomial? 5x² + 8x³ + 4- 6x² - 3x5

geniusboy [140]

Answer:

The degree of polynomial is 5.

Step-by-step explanation:

I suppose the polynomial is $\displaystyle{5x^2+8x^3+4-6x^2-3x^5}$ . To find the which degree this polynomial is, we consider the highest exponent of the term which is $\displaystyle{3x^5}$ , the 5 is our highest degree of the term and thus, 5 is our highest degree of polynomial.
