What is x and what converse is used to find x

Mathematics
1 answer:
mrs_skeptik [129]3 years ago
8 0

Answer:

4

Step-by-step explanation:

the third angle of the inner triangle is defined by using the rule that the sum of all angles in a triangle must be 180 degrees. let's call this angle a

180 = 48 + 16x + a

132 - 16x = a

and then we know that both angles, 28x and a together must also be 180, as they are complementing each other to cover the whole top of the base line.

so,

28x + 132 - 16x = 180

12x = 48

x = 4

Find the obtuse angle the line y-2x=7 makes with the x- axis
Kazeer [188]
In analytical geometry, there are already derived equations to find the distance of lines and points as well as the angle made between two lines. As special case is when the other line is one of the coordinate axis. Then, the formula can be simplified to

tan θ =m, where m is the slope of the equation

In the next step, we also incorporate operations of calculus. Since the slope is equal to Δy/Δx, this is equivalent to dy/dx in calculus. Therefore, you can find the slope by differentiating the equation in terms of x.

<span>y-2x=7
y = 2x+7
dy/dx = 2 =m

So,

tan </span>θ = 2
θ = tan⁻¹(2)
θ = 63.43°

You have 23 1/2 pounds of blueberries to store in freezer bags. Each bag holds 3 3/4 pounds of blueberries. What is the minimum
monitta

Answer:

The minimum number of freezer bags needed to store all the blueberries is 7

Step-by-step explanation:

we know that

To find out the number of freezer bags needed , divide the total pounds of blueberries by 3 3/4, but first convert mixed number to an improper fraction

23\frac{1}{2}\ lb=\frac{23*2+1}{2}=\frac{47}{2}\ lb

3\frac{3}{4}\ lb=\frac{3*4+3}{4}=\frac{15}{4}\ lb

\frac{47}{2}:\frac{15}{4}=\frac{47*4}{2*15} =\frac{94}{15}=6.3\ bags

Round up

7 bags

therefore

The minimum number of freezer bags needed to store all the blueberries is 7

La funcion que representa el beneficio obtenido por una empresa si vende x unidades de uno de sus productos es f(x)= -70x^2+2800
DerKrebs [107]

Answer:

20

Step-by-step explanation:

La función es

f(x)=-70x^2+2800x-45000

Diferenciando con respecto a x obtenemos

f'(x)=-140x+2800

Igualar con cero

0=-140x+2800\\\Rightarrow x=\dfrac{2800}{140}\\\Rightarrow x=20

Doble derivada de la función

f''(x)=-140

Entonces, la función es máxima cuando el número de unidades vendidas,  x=20,
