Answer:

1) y = 1/2 x + 3 and y = 1/2 x  are parallel

2) y = 1/2 x + 4   and   y = 1/2 x + 1  are parallel

Step-by-step explanation:

Two lines are parallel only if their slope is equal.

1)

In the first problem:

y = 1/2 x + 3 and y = 1/2 x have same slope ( i.e slope = 1/2)

That means these two equations are parallel to each other.

2)

In the second problem:

y = 1/2 x + 4   and   y = 1/2 x + 1 have same slope( i.e slope = 1/2)

Hence above two equations are parallel to each other.

What is the shaded portion of the circle
blagie [28]

Answer:

(5\pi-11.6)\ ft^{2}

Step-by-step explanation:

we know that

The area of the shaded region is equal to the area of the sector minus the area of the triangle

step 1

Find the area of the circle

the area of the circle is equal to

A=\pi r^{2}

we have

r=5\ ft

substitute

A=\pi (5)^{2}

A=25\pi\ ft^{2}

step 2

Find the area of the sector

we know that

The area of the circle subtends a central angle of 360 degrees

so

by proportion find out the area of a sector by a central angle of 72 degrees

\frac{25\pi}{360}=\frac{x}{72}\\ \\x=72*25\pi /360\\ \\x=5\pi\ ft^{2}

step 3

Find the area of triangle

The area of the triangle is equal to

A=\frac{1}{2}(2.9+2.9)(4)= 11.6\ ft^{2}

step 4

Find the area of the shaded region

Subtract the area of the triangle from the area of the sector

(5\pi-11.6)\ ft^{2}

When planning road development, the road commission estimates the future population using the function represented in the table,
Sindrei [870]

The significance of 160,000 in the function is the initial population at the time of the estimation.

The correct option is (C)

<h3>What is data?</h3>

A collection of facts, such as numbers, words, measurements, observations or even just descriptions of things.

Given:

As per the table attached below:

F(x) signify the total population when the time was x hour.

So,  160,000 in the function signifies that the population at starting i.e., initial point.

Please Answer!!!!
Morgarella [4.7K]

Answer:

A). F = \frac{9C}{5}+32

B). 374°F

Step-by-step explanation:

A). Formula to convert the temperature from degree centigrade to °F is,

    C = \frac{5}{9}(F-32)

    We have to solve the formula to get the value of F,

    9 × C = 9\times \frac{5}{9}(F-32)

    9C = 5(F - 32)

    \frac{9C}{5}=\frac{5(F-32)}{5}

    \frac{9C}{5}=(F-32)

    F = \frac{9C}{5}+32

B). In this part we have to find the value of 190° C in °F.

    From the formula given in part (A),

    F = \frac{9\times 190}{5}+32

       = 374°

    Therefore, 190°C = 374°F
