Un sistema de coordenadas cartesianas es un sistema de coordenadas que especifica cada punto de forma única en un plano mediante un conjunto de coordenadas numéricas, que son las distancias con signo al punto desde dos líneas orientadas perpendiculares fijas, medidas en la misma unidad de longitud.

What is a reference angle?

frosja888 [35]

A reference angle is formed by the terminal side and the horizontal axis (aka x axis). Replace each "access" with "axis" as those are typos. By definition, a reference angle is between 0 and 90 degrees so the angle is always acute.

What could be a possible value for x ? a. 3.5 b. 4.0 c. 4.5 d. 5.5

meriva

Answer:

The answer is (a) ⇒ x = 3.5

Step-by-step explanation:

In ΔABZ use the sin rule to find ∠ABZ and ∠BAZ

∵ AB/sin50° = AZ/sin∠ABZ

∴ 8.8/sin50° = 4.79/sin∠ABZ

∴ sin∠ABZ = (4.79 × sin50) ÷ 8.8

∴ sin ABZ = 0.416971

∴m∠ABZ = 24.64°

∴ m∠BAZ = 180 - (50 + 24.64) = 105.36°

In ΔABZ use the cosine rule to find BZ

(BZ)² = (BA)² + (AZ)² - 2(BA)(AZ)cos∠BAZ

∵ (BZ)² = (8.8)² + (4.79)² - 2(8.8)(4.79)cos105.36°

∴ (BZ)² = 122.7147953

∴ BZ = 11.078

Use the cosine rule in ΔCBZ to find CZ

(CZ)²= (BC)² + (BZ)² - 2(BC)(BZ)cos∠B

∵ (CZ)² = (4.79)² + (11.078)² - 2(4.79)(11.078)cos39²

∴ (CZ)² = 63.18982803

∴ CZ = 7.949

∵ CZ = 2x + 1

∴ 2x + 1 = 7.949

∴ 2x = 7.949 - 1 = 6.949

∴ x = 6.949 ÷ 2 = 3.47 ≅ 3.5

We have a negative relationship between number of drinks consumed and number of marks in a driving test. One individual scores 3

lbvjy [14]

Answer:

C. Driving test scores (y-axis) will be 9 [individual who scored 3 on drink consumption and 3 [individual who scored 5 on drink consumption].

Correct as we can see:

$y(3) =-3(3) +18 = -9 +18 =9$

$y(5) =-3(5) +18 = -15 +18 =3$

Step-by-step explanation:

Let's define some notation:

y= represent the driving test scores

x= represent the number of drinks consumed

We know this info given: "What will be their respective scores on the driving test if the intercept is 18 and the slope -3?" So then we can create the following linear model:

$y = -3x +18$

And now we have two values for x we can replace and see what we got:

$y(3) =-3(3) +18 = -9 +18 =9$

$y(5) =-3(5) +18 = -15 +18 =3$

And if we analyze one by one the options we got this:

A. Driving test scores (y-axis) will be 27 [individual who scored 3 on drink consumption and 33 [individual who scored 5 on drink consumption].

False.

$y(3) =-3(3) +18 = -9 +18 =9$

$y(5) =-3(5) +18 = -15 +18 =3$

B. It is not possible to predict from negative relationships.

False, we have the linear model given and we can find the predicted values.

C. Driving test scores (y-axis) will be 9 [individual who scored 3 on drink consumption and 3 [individual who scored 5 on drink consumption].

Correct as we can see before:

$y(3) =-3(3) +18 = -9 +18 =9$

$y(5) =-3(5) +18 = -15 +18 =3$

D. Driving test scores (y-axis) will be 51 and 87 [individual who scored 5 on drink consumption].

False.
