Describe the graph of of the equation x = -2. Is the equation a function?
Cloud [144]
In the event that a line has no y-intercept, that implies it never converges the y-intercept, so it must be parallel to the y-intercept. This implies it is a vertical line, for example, . This slant of this line is vague. In the event that the line has no x-intercept, at that point it never meets the x-intercept, so it must be parallel to the x-pivot. 

If x-intercept is -2 the line would be vertical as the y-intercept = 0.

tia_tia [17]

Answer:

10 Square Inches

Step-by-step explanation:

<u>Trapezoid</u>

Base =12 inches

Height =10 inches

Top side= 10 inches.

Area of a Trapezoid=\frac{1}{2}(a+b)h, $where a and b are the lengths of the base and top respectively$

=\frac{1}{2}(10+12)*10\\=5*22=110 \:Square\:Inches

Area of the Trapezoid=110 Square Inches

<u>Rectangle</u>

Base = 12 inches

Height =10 inches.

Area of a Rectangle=Base X Height

=12 X 10

=120 Square Inches

<u>Difference in Area between the two packages</u>

Difference=Area of Rectangle-Area of Trapezoid

=120-110

=10 Square Inches

In the calm waters of an inlet, Manon's boat moves with a velocity (speed and direction) vector \vec{b_1} = (3,4) b 1 ​ ​ =(3,4)
andrew-mc [135]

Answer with Step-by-step explanation:

We are given that

b_1=(3,4)

b_2=(1,1)

We have to find the speed of river's current and the direction of current flowing.

b=b_2-b_1=(1,1)-(3,4)=(-2,-3)

Speed of river's current=\mid b\mid

Speed of river's current=\sqrt{(-2)^2+(-3)^2}

Speed of river's current=\sqrt{13} m/s

By using the formula

\mid r\mid =\sqrt{x^2+y^2}

Direction of current flowing,\theta=tan^{-1}(\frac{y}{x})

\theta=tan^{-1}(\frac{-3}{-2})=56.3^{\circ}

The angle lies in third quadrant therefore

\theta=180+56.3=236.3^{\circ}

Lily is a lilypad in a small pond. Lily doubles in size each day. On the 20th day she covers the whole pond. On what day was Lil
svetoff [14.1K]

Answer:

19th day

Step-by-step explanation:

So say Lily was 1 when Lily was planted

First day Lily is 2

Second day Lily is 4

Third day Lily is 8

etc...

See the pattern?

The pattern is 2^x

On the 20th day, Lily was 2^20

So when Lily was half, Lily was 2^20 / 2

2^x = 2^20 / 2

2^x = 2^19

On the 19th day, Lily was half.
