Answer: Adiya's approach is incorrect. To construct a perfect square trinomial, one must isolate the constant on one side of the equation. The coefficient of the term with an exponent of 1 regarding the variable is essential to calculate the constant in the perfect square trinomial. The first step for Adiya should be to reposition the 20x term to the same side of the equation as x2. Then, she should divide 20 by 2, square that result, and add 100 to both sides.

Which equation represents a line that passes through (–9, –3) and has a slope of –6?
Leona [4187]

Answer:

The equation of the line required is y=-6x-57.

Step-by-step explanation:

The point-slope form of a line is

y-y_1=m(x-x_1)

Here, m represents the slope of the line.

It is given that a line passes through the point (–9, –3) with a slope of –6.

By substituting m=-6, x₁=-9, and y₁=-3 into the equation above, you get:

y-(-3)=-6(x-(-9))

y+3=-6x-54

Next, subtract 3 from each side.

y=-6x-54-3

y=-6x-57

Therefore, the final equation of the line is y=-6x-57.

Andrei wants to fill a glass tank with marbles, and then fill the remaining space with water. WWW represents the volume of water
PIT_PIT [3949]

Answer:

32 Liters

Step-by-step explanation:

Within the glass tank:

W = represents the amount of water Andrei will use (in liters)

n = Number of marbles

Given the following: W=32-0.05n

The tank's volume is the amount of water plus the cumulative volume of n marbles added.

Thus:

W+0.05n=32

Tank volume = 32 Liters

Answer:

El volumen del cilindro mostrado en la figura es de 628 metros cúbicos

Explicación paso a paso:

La figura proporcionada se refiere a un cilindro

La altura del cilindro = h = 8 metros

El radio de la base del cilindro = r = 5 metros

Ahora, definamos el volumen del cilindro = V m³

Por lo tanto, el volumen del cilindro está dado por V = \pi×r²×h

donde r es el radio de la base

y h es la altura del cilindro

El valor de \pi = 3.14

Así que, V = \pi × r² × h

O, V = 3.14 × (5)² × 8

O, V = 3.14 × 25 × 8

o, V = 628 m³

Así que, el volumen del cilindro es V = 628 m³

Por lo tanto, el volumen del cilindro mostrado en la figura es de 628 metros cúbicos

A random sample of 65 high school seniors was selected from all high school seniors at a certain high school. The following scat
babunello [3666]

Step-by-step explanation:

The equation for the best fitting line is y = 2.599x + 105.08. When x is set to 20, the predicted height becomes y = 157.06. However, the actual height recorded is 160 cm, therefore, the residual is calculated as:

160 cm − 157.06 cm = 2.94 cm
