Need help will give brainliest

stira [4]

Answer:

106

Step-by-step explanation:

c(106)=x^(2)-17x+66

u put 106 into the formula by squaring 106 which gives you 11236

timesing 17 x 106 = which is 1802

then the formula looks like this c(106)=11236-1802+66

this then equals $9500, meaning the answer is 106

pls mark brainliest....:)

Use the properties of logarithms to write the following expression as one logarithm.

raketka [301]

Answer:

Step-by-step explanation:

hi! the log properties say that when logs are multiplied as log(xy), they can be expanded and added like log(x)+log(y). when logs are divided like log(x/y), they can be expanded as log(x)-log(y). when the log has an exponent like log(x^y), the exponent can be added to the front of the log like ylog(x). we can use these properties for this problem.

ln(x^3)+ln(y^2)-ln((x+1)^4)

ln(x^3*y^2)-ln((x+1)^4)

$ln(\frac{(x^3y^2)}{((x+1)^4)})$

Find the volume of the composite figure.

lana66690 [7]

Answer:

To find the volume of this composite figure, we will need to first separate it into the two rectangular prisms that make up the larger figure (You seem to have already figured that step out =) ). Let us start with the larger prism. The formula for the volume of a rectangular prism is length * width * height.

WEDNESDAY: Use the quadratic formula to solve the following: 3x^2 - 6x-12 = 0*

Pepsi [2]

Answer:

a.) 3.236 or -1.236

Step-by-step explanation:

Used an online calculator for this answer...

Using the Quadratic Formula where

$x = \frac{ -b \pm \sqrt{b^2 - 4ac}}{ 2a }\\x = \frac{ -(-6) \pm \sqrt{(-6)^2 - 4(3)(-12)}}{ 2(3) }\\x = \frac{ 6 \pm \sqrt{36 - -144}}{ 6 }\\x = \frac{ 6 \pm \sqrt{180}}{ 6 }$

The discriminant b^2−4ac > 0

so, there are two real roots.

Simplify the radical...

$x = \frac{ 6 \pm 6\sqrt{5}\, }{ 6 }\\x = \frac{ 6 }{ 6 } \pm \frac{6\sqrt{5}\, }{ 6 }\\x = 1 \pm \sqrt{5}\,$

This simplifies to...

$x = 3.23607\\x = -1.23607$
