Answer:

1574yd^2

Step-by-step explanation:

i split into 3, 2 rectangles and a triangle

40 x 30 = 1200

30 - 8 = 22 (height)

60 - 40 = 20 (width)

14 x 22 = 308

20 - 14 = 6 (base of triangle)

formula of triangle = (b x h) / 2

6 x 22 = 132 / 2 = 66

1200 + 66 + 308 = 1574

Answer:

2 rational solutions

Step-by-step explanation:

the degree of the polynomial (the highest exponent of the variable) defines how many solutions there are.

that means for how many values of x the result y is 0 (how many x-axis interceptions there are or should be).

so, a quadratic equation has 2 such solutions.

there are a few different cases how these solutions present themselves :

"normal case" : all the solutions are real (not only rational) numbers, and the curve has that many different x- acid interceptions.

a turn of the curve leads to only "touching" the x-axis : this is just a special case that the curve is "too high" or "too low" and the regular 2 intersects merge into 1. there are formally still 2 solutions, but they are identical.

there can be "S-curves" especially for higher degrees (3 and up) with the center smoothing in with the x-axis : this is similar but can merge even more than 2 solutions into 1.

the curve is really "too high" or "too low" and never even touches the x-axis : then the solutions are irrational.

the general solution for a quadratic equation is

x = (-b ± sqrt(b² - 4ac))/(2a)

the discriminate is (b² - 4ac).

if this is a positive perfect square, then the square root is a perfect integer. in fact, 2 perfect integers (+ and -).

and so we get two solutions with integer/integer and they are therefore 2 rational solutions.

Answer:

y - 2 = 2(x + 5)

Step-by-step explanation:

Point slope:

    y - y₁ = m(x - x₁)

Given P(-5, 2) and slope m = 2:

  y - 2 = 2(x - (-5))

  y - 2 = 2(x + 5)

Answer:

[tex]a_{n}[/tex] = - 8n + 10

Step-by-step explanation:

there is a common difference between consecutive terms , that is

- 6 - 2 = - 14 - (- 6) = - 22 - (- 14) = - 8

this indicates the sequence is arithmetic with nth term

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

here a₁ = 2 and d = - 8 , then

[tex]a_{n}[/tex] = 2 - 8(n - 1) = 2 - 8n + 8 = - 8n + 10

Answer:

A) Se requiere una tabla con una longitud de 2.213 varas para fabricar la mesa.

B) El lote de José tiene una extensión de 536.481 varas cuadradas.  

Step-by-step explanation:

A) La vara es una unidad de longitud equivalente a 0.836 metros. También sabemos que un cuadrado es una figura geométrica con cuatro lados de igual longitud y cuatro ángulos rectos, de modo que la longitud y ancho de la mesa es igual. Entonces, el largo de la tabla, esto es, la superficie superior de la mesa, tiene una medida de 1.85 metros.

A continuación, realizamos la regla de tres para determinar su equivalente en varas:

[tex]x = 1.85\,m\times\frac{1\,vara}{0.836\,m}[/tex]

[tex]x = 2.213\,varas[/tex]

Se requiere una tabla con una longitud de 2.213 varas para fabricar la mesa.

B) La vara es una unidad de longitud equivalente a 0.836 metros. Una vara cuadrada es una unidad de área y es igual a:

[tex]r = (0.836\,m)\cdot (0.836\,m)[/tex]

[tex]r = 0.699\,m^{2}[/tex]

De manera semejante, tenemos que el área del lote de Jose es un rectángulo y que se calcula como sigue en metros cuadrados:

[tex]A = l\cdot w[/tex] (Eq. 1)

Donde:

[tex]A[/tex] - Área del lote de José, medido en metros cuadrados.

[tex]l[/tex] - Largo del lote de José, medido en metros cuadrados.

[tex]w[/tex] - Ancho del lote de José, medido en metros cuadrados.

Si [tex]l = 25\,m[/tex] y [tex]w = 15\,m[/tex], entonces el área del lote es:

[tex]A = (25\,m)\cdot (15\,m)[/tex]

[tex]A = 375\,m^{2}[/tex]

Por último, hallamos el área en varas cuadradas mediante la siguiente regla de tres:

[tex]x = 375\,m^{2}\times \frac{1\,vara}{0.699\,m^{2}}[/tex]

[tex]x = 536.481\,varas^{2}[/tex]

El lote de José tiene una extensión de 536.481 varas cuadradas.

Answer:

A six-sided number cube is rolled twice the expression 1/6 x 1/6 can be used to find P(5, then3). The correct option is D.

Probability is a measure of how likely an event is to occur. Many events are impossible to predict with absolute certainty.

The probability of rolling a 5 and then a 3 is independent, so we can find the probability by multiplying the probability of rolling a 5 on the first roll by the probability of rolling a 3 on the second roll.

The probability of rolling a 5 on the first roll is 1/6, and the probability of rolling a 3 on the second roll is also 1/6.

Therefore, the expression that can be used to find P(5, then 3) is: B. 1/6 * 1/6

Answer: yes

Step-by-step explanation:

They run side by side together

As a rule, parallel lines will always have the same slope.

However, they need to also have different y-intercepts.

Since these two lines have the same steepness or slope

and they have different y-intercepts, we say they are parallel.

Step-by-step explanation:

16/4 = 4

100/25 = 4

4 = 4

The length of the roof line is equal to 17.4 feet and the depth of the shed is 15.07 feet.

Given the following data:

First of all, we would assign a variable to the length of the roof line and depth of the shed from front to back respectively.

Let the length of the roof line be h.

Let the depth of the shed be d.

From the image attached, we would determine the length of the opposite side as follows:

[tex]Opp=20.2 -11.5[/tex]

Opposite side = 8.7 feet.

Next, we would determine the length of the roof line by using Sine trigonometric:

[tex]Sin \theta = \frac{Opp}{Hyp} \\\\Sin30 =\frac{8.7}{h} \\\\0.5=\frac{8.7}{h}\\\\h=\frac{8.7}{0.5}[/tex]

h = 17.4 feet.

For the depth;

We would determine the length of the roof line by using Tan trigonometric:

[tex]Tan \theta =\frac{Opp}{Adj} \\\\Tan 30 =\frac{8.7}{d} \\\\0.5774=\frac{8.7}{d}\\\\d=\frac{8.7}{0.5774}[/tex]

d = 15.07 feet.

Answer:

Each one of them spent $38

Each one of them played 6 games.

Step-by-step explanation:

The number of games be represented by g

Colette went to play miniature golf on Monday, when it cost $14 to rent the club and ball, plus $4 per game.

$14 + $4 × g

= 14 + 4g

Maddie went Thursday, paying $6 per game, plus rental fees of $2.

$2 + $6 × g

= 2 + 6g

The equation is :

14 + 4g = 2 + 6g

We solve for g

Collect like terms

14 - 2 = 6g - 4g

12 = 2g

g = 12/2

g = 6

How many games did each one play?

Each one of them played 6 games.

How much did each one spend?

For Colette

The amount she spent :

14 + 4g

=$14 + 4 × 6

= $14 + 24

= $38

For Maddie

2 + 6g

=$ 2 + 6(6)

=$ 2 + 36

= $38
