It's x = -3, -8
Because to equal 0 one of the values has to be 0 to be multiplied and get 0.

Todd placed 32 square tiles along the edge of his wooden dining room table, as shown below. Note: Figure is not drawn to scale.

Flauer [41]

Answer:

The diagonal is 421.

Step-by-step explanation:

This is a difficult question. To find the diagonal, you need to find the base and the height of the square. After that, you need to make it a triangle, by using this equation; $A=\frac{1}{2} BH$ (A being area, B being base, and H being height) then find the length of the hypotenuse of the triangle, which I will do for you.

$32*13=416$ The B and H = 416. Plug it into the equation now;

$A=\frac{1}{2}(416*416)\\\\\\A=\frac{1}{2} 173,056\\\\\\A=86,528$ Now that you have done that, we know that the area of our new triangle is 86,528.

The diagonal is: $421$

The label on the car's antifreeze container claims to protect the car between −40°C and 140°C. To covert Celsius temperature to

telo118 [61]

Answer:

$-40$

Step-by-step explanation:

We must convert the given temperatures from degrees Celsius to degrees Fahrenheit

The formula is:

$C=\frac{5}{9}(F-32)$

Where C is the temperature in degrees Celsius and F is the temperature in degrees Fahrenheit

Then we must replace the temperature in degrees Celsius and solve the equation for F

$C*\frac{9}{5}=(F-32)$

$F=C*\frac{9}{5}+32$

$F=(-40)*\frac{9}{5}+32$

$F=-40\ \°F$

$F=(140)*\frac{9}{5}+32$

$F=284\ \°F$

The Fahrenheit temperature range in which the antifreeze protects the car is:

$-40$

Consider the equation below. (If an answer does not exist, enter DNE.) f(x) = x^3 − 3x^2 − 9x + 4 (a) Find the interval on which

Eduardwww [97]

Answer:

(-∞, -1 )∪(3, ∞)

Step-by-step explanation:

Given function,

$f(x) = x^3 - 3x^2 - 9x + 4$

Differentiating with respect to x,

$f'(x)=3x^2-6x-9$

For increasing or decreasing,

f'(x) = 0

$\implies 3x^2-6x-9=0$

By quadratic formula,

$x=\frac{-(-6)\pm \sqrt{(-6)^2-4\times 3\times -9}}{6}$

$=\frac{ 6\pm \sqrt{36+108}}{6}$

$=\frac{6\pm \sqrt{144}}{6}$

$\frac{6\pm 12}{6}$

$\implies x = 3\text{ or } x = -1$

In interval (-∞, -1 ), f'(x) = positive,

⇒ f(x) is increasing on (-∞, -1 ),

In interval (-1, 3), f'(x) = negative,

⇒ f(x) is decreasing on (-1, 3),

In interval (3, ∞), f'(x) = positive,

⇒ f(x) is increasing on (3, ∞),
