Answer:

Malcom's family travel 15 miles per hour faster than Theo's

Step-by-step explanation:

<em>See attachment for complete question</em>

Given

Malcom's Family:

d = 65t

To determine the equation of Theo's family, we refer to the attached graph.

From the graph:

t = 1; d = 50

t = 2; d = 100

First, we determine the slope, m:

m = \frac{d_2 - d_1}{t_2 - t_1}

m = \frac{100 - 50}{2- 1}

m = \frac{50}{1}

m = 50

Next, we determine equation for Theo's family using:

d - d_1 = m(t - t_1)

d - 50 =50(t - 1)

d - 50 =50t - 50

Add 50 to both sides

d - 50 +50=50t - 50 + 50

d =50t

So, we have the following:

d = 65t --- For Malcom's family

This implies that Malcom's family travel at 65 miles per hour

d =50t --- For Theo's family

This implies that Theo's family travel at 50 miles per hour

The difference between this rates is:

Rate = 65t - 50t

Rate = 15t

<em>Which implies that Malcom's family travel 15 miles per hour faster than Theo's</em>

Determine the central and radius of the circle of equation given below<br> x2+y2-4x+6y-12=0
Marianna [84]

Answer:

centre = (2, - 3 ) and radius = 5

Step-by-step explanation:

the equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k ) are the coordinates of the centre and r is the radius

given

x² + y² - 4x + 6y - 12 = 0 ( add 12 to both sides )

x² + y² - 4x + 6y = 12 ( collect x/ y terms )

x² + 4x + y² + 6y = 12

using the method of completing the square

add ( half the coefficient of the x/ y terms )² to both sides

x² + 2(-2)x + 4 + y² + 2(3)y + 9 = 12 + 4 + 9

(x - 2)² + (y + 3)² = 25 ← in standard form

with (h, k ) = ( 2, - 3 ) and r = \sqrt{25} = 5

A small plane is flying a banner in the shape of a rectangle. The area of the banner is 144 square feet . The width of the banne
Margarita [4]

Answer:

The answer to your question is width = 6 ft; length = 24 ft

Step-by-step explanation:

Data

Area = 144 ft²

width = w

length = l

The width is 1/4 of the length

Formula

Area = width x length = w x l

Length = 4 width     l = 4w

Process

1.- Substitute length in the first equation

                       Area = w(4w)

Simplify

                       Area = 4w²

2.- Solve for w

                      w = \sqrt{\frac{Area}{4}}

Substitution

                      w = \sqrt{\frac{144}{4}}

Simplification

                      w = \sqrt{36}

Result

                      w = 6 ft

3.- Find l

                       l = 4(6)

                       l = 24 ft
