Answer:

y=-4x+1

Step-by-step explanation:

Answer:

Step-by-step explanation:

Let be $y = k\cdot x +1$ the expression of the line, where $x$ and $y$ are the independent and dependent variables, respectively. If we know that $x = 2$ and $y = -7$ , the value of $k$ is:

$-7 = 2\cdot k +1$

$2\cdot k = -8$

$k = -4$

The equation of the line is $y = -4\cdot x +1$ , which is graphed below.

Which of the following trigonometric inequalities has no solution over the interval 0 ≤ x ≤ 2pi radians?

valentinak56 [21]

Answer:

A .cos(x)<1

Step-by-step explanation:

According to the first inequality

cos(x)<1

x < arccos 1

x<0

This therefore does not have a solution within the range 0 ≤ x ≤ 2pi

x cannot be leas than 0. According to the range not value, 0≤x which is equivalent to x≥0. Thus means otvis either x = 0 or x> 0.

For the second option

.cos(x/2)<1

x/2< arccos1

x/2<0

x<0

This inequality also has solution within the range 0 ≤ x ≤ 2pi since 0 falls within the range of values.

For the inequality csc(x)<1

1/sin(x) < 1

1< sin(x)

sinx>1

x>arcsin1

x>90°

x>π/2

This inequality also has solution within the range 0 ≤ x ≤ 2pi since π/2 falls within the range of values

For the inequality csc(x/2)<1

1/sin(x/2) < 1

1< sin(x/2)

sin(x/2)> 1

x/2 > arcsin1

X/2 > 90°

x>180°

x>π

This value of x also has a solution within the range.

Therefore option A is the only inequality that does not have a solution with the range.

Rudiy27

Answer:

A parallelogram can have 2 pairs of parallel sides.

Step-by-step explanation:

Think of a rectangle for a parallelogram. It has 2 pairs of parallel sides which makes it a parallelogram. The same for a square as well as it has 2 parallel pairs. Just remember that a parallelogram always has 2 pairs of parallel sides.

A couple of college students frustrated with the current class registration process decide to survey 500 random students on camp

aleksklad [387]

<h3>♫ - - - - - - - - - - - - - - - ~Hello There!~ - - - - - - - - - - - - - - - ♫</h3>

➷ Standard deviation = $\sqrt{(n*p)(1 - p)}$

Substitute the values in:

$\sqrt{(500 *0.84)(1-0.84)}$ = 8.1975...

This can be rounded to give an approximate answer of 8.2

The answer is option A.

A barrel of oil was filled at a constant rate of 7.9 gal/min. The barrel had 12 gallons before filling began.

jenyasd209 [6]

The equation that models this situation is z = 7.9y + 12.

A linear equation is a function that has a single variable raised to the power of 1. An example is x = 4y + 2.

Where:

2 is the constant
x = dependent variable
y = independent variable

From the equation given, 12 would be the constant, the independent variable would be 7.9 and z would be the dependent variable.

z = 7.9y + 12

Here is the complete question: A barrel of oil was filled at a constant rate of 7.9 gal/min. The barrel had 12 gallons before filling began. write an equation in standard form to model the linear situation.
