Answer:

y = 5

Step-by-step explanation:

The equation of a horizontal line is

y = c

where c is the value of the y- coordinates the line passes through.

The line passes through (- 2, 5) with y- coordinate 5, thus

y = 5 ← equation of horizontal line

Which expression is equivalent to the polynomial x2-x-6

OLEGan [10]

Answer:

$(x - 2)(x + 3)$

Step-by-step explanation:

The given polynomial is

${x}^{2} - x - 6$

The factors of -6 that sums up to -1 are -3,2.

We split the middle term to obtain:

${x}^{2} -3 x + 2x - 6$

We factor to get:

$x(x - 3) + 2(x - 3)$

We factor further to get:

$(x - 3)(x + 2)$

The polynomial is equivalent to:

$(x - 3)( x + 2)$

6. A ship is on the surface of the water, and its radar detects a submarine at a distance of

Minchanka [31]

Answer:

the submarine is 92.994 feet ≈ 93 feet deep from the surface of the water

Step-by-step explanation:

We can think in a triangle where the hypotenuse is the detection distance and the angle with the horizontal surface of water is the depression angle, then the underwater distance is the vertical side of the triangle.

If we denote Ф as the angle of depression ,d as the detection distance and x as the unknown depth of the submarine, using trigonometry:

x = d* sin Ф

thus

x= d * sin Ф = 238 feet * sin 23° = 92.994 feet ≈ 93 feet

Which quadratic equation fits the data in the table? (PICTURE OF TABLE ATTACHED)

Paha777 [63]

The correct quadratic equation for that set of points is:
$y=x^2+7x+1$

To check it, simply put first and last pair of points and assure the equality:
$-11=(-3)^2+7*(-3)+1$
$-11=9-21+1$
$-11=-11$

$79=6^2+7*6+1$
$79=36+42+1$
$79=79$

Cory gains 3 cars a year and Roger 1.
Cory - 18 (6 x 3) : Roger - 6 (6 x 1)
I Cory was to stop receiving cars for 3 years, while Roger kept getting them for 3 then they would have the same amount.
