98 POINTS!!!<br><br>Write a polynomial function in standard form given the zeros<br><br><br>±√5 , 7
Neporo4naja [7]

Answer:

Step-by-step explanation:

Knowing the three zeros of the equation, we can set it up as follows:

(x - \sqrt{5})(x + \sqrt{5})(x - 7)

Multipying the first two expressions together gives us the following:

(x^{2} - 5)(x - 7)

Multiplying the two expressions together gives us the following:

x^{3} - 7x^{2} - 5x + 35

What is the volume in cubic inches of the cylinder, rounded to the nearest cubic inch?
son4ous [18]

\bf \textit{volume of a cylinder}\\\\ V=\pi r^2 h~~ \begin{cases} r=radius\\ h=height\\ \cline{1-1} r=9\\ h=7 \end{cases}\implies V=\pi (9)^2(7) \\\\\\ V=\pi (81)(7)\implies V=567\pi \implies V\approx 1781.28\implies \stackrel{\textit{rounded up}}{V=1781}

What is the solution of log(t-3)=log(17-4t)?
solmaris [256]
Log=13
t=4
So, this is because they already given you t because the four is on front of it that gives you your value. From there you will proceed to j7st do the math in your parentheses. You should get log=(1) & log=(13) because 1 times anything is that number just use the inverse of each would be eachother. So, 1x13 is the same as 13x1

HELP
andreev551 [17]

Answer:

A. y = 80x

B. g(x) = 80x

C. To graph the equation, plot a point at (0,0) and a point at (1,80). Connect the points. Continue adding points by moving up $80 and over 1 day.

Step-by-step explanation:

Part A:  

To write an equation, use y= mx where m is the slope, x is the number of days, and y is the rent cost.

x and y remain the same in the equation.

To find m, use the slope formula with (5,465) and (7, 625).

m=\frac{y_2-y_1}{x_2-x_1}= \frac{625-465}{7-5} =\frac{160}{2} =80

It costs $80 a day.

The equation is y = 80x.

Part B:  

Function notation replaces Y as g(x). So the equation is g(x) = 80x.

Part C:

To graph the equation, plot a point at (0,0) and a point at (1,80). Connect the points. Continue adding points by moving up $80 and over 1 day.
