Each relationship's proportionality constants are k=3 and k=1, respectively.

The ratio connecting two given numbers in what is known as a proportional relationship is the constant of proportionality. Constant ratio, constant rate, unit rate, constant of variation, and even rate of change are other names for the constant of proportionality.

Given that the relationship is proportional,

the equation linking the quantities is y = k x k, where k is the proportional constant.

Divide both sides by x to determine k

k = y/x

For graph a use the point (2, 6 ), then

k = 6/2

= 3

For graph b use the point (4, 4 ), then

k = 4/4

Step-by-step explanation:

The equation of the line as it passes through the point (-6, 1) is

y = 3x/2 + 10

Slope is the same as gradient which is the ratio of change in y to change in x. That is,

gradient m = Δy / Δx

Given that the equation of the line passes through the point (-6, 1) and is perpendicular to the graph of 2x + 3y = -5

Let us first find the slope, 3y = -2x - 5

y = -2x/3 - 5/3

Slope m = -2/3

Let us use the formula Mm = -1

M = -1/m

M = -1 × -3 /2

M = 3/2

The equation of the line as it passes through the point (-6, 1) will be

M = (Y - Y1) / (X - X1)

3/2 = (y - 1) / (x + 6)

Cross multiply

2(y - 1) = 3(x + 6)

2y - 2 = 3x + 18

Collect the like time

2y = 3x + 18 + 2

2y = 3x + 20

y = 3x/2 + 10

Therefore, the equation of the line as it passes through the point (-6, 1) is y = 3x/2 + 10

Given the area, the lengths of the diagonals p and q of the rhombus are 4√7 cm and 12√7 cm respectively.

A rhombus which is called an equilateral quadrilateral is simply a quadrilateral whose all four sides have the same length.

The area of a rhombus is expressed as;

A = ( p × q )/2

Where p and q are the diagonals

Given the data in the question;

Let one of the diagonal be x.

Plug in the given values into the equation above and solve for x.

A = ( p × q )/2

168 = ( x × 3x )/2

168 = ( 3x² )/2

3x² = 168 × 2

3x² = 336

Divide both sides by 3

x² = 112

Take the square root of both sides

x = ±√112

x = ±4√7

Since the dimension of the rhombus cannot be negative,

x = 4√7

Hence, the length of the diagonals are;

Diagonal p = x = 4√7 cm

Diagonal q = 3x = 3( 4√7 ) = 12√7 cm

Given the area, the lengths of the diagonals p and q of the rhombus are 4√7 cm and 12√7 cm respectively.

The equation shown on the graph is y = 2x + 3. The correct answer is C. y = 2x +3

From the question, we are to determine the equation that represent the given line

To determine the equation, we will pick two points on the line and determine the equation of the line

Picking the points (0, 3) and (3, 9)

Using the formula for the finding the equation of a line with two given points

(y - y₁)/(x - x₁) = (y₂ - y₁)/(x₂ - x₁)

x₁ = 0

y₁ = 3

x₂ = 3

y₂ = 9

Then,

(y - 3)/(x - 0) = (9 - 3)/(3 - 0)

(y - 3)/x= 6/3

(y - 3)/x= 2

y - 3 = 2x

y = 2x + 3

Hence, the equation shown on the graph is y = 2x + 3. The correct answer is C. y = 2x +3

Answer:

this is the answer of this question

Answer:

a= 20

b= 70

c= 20

d=70

e=110

Step-by-step explanation:

a + the 70 degree angle have to equal 90 degrees (the right angle marking) and the same with b + a. So to ind a, you do 90-70 and to find b, because you now have the value of a, you do 90-20.

a+b+c+70 is equal to a 180 degree angle, so since you know the value of a and b, now you can figure out c by doing 180-(70+20+70).

d and the 70 degree angle are vertical angles so they are equal to each other.

lastly for e, d+e is equal to 180 degrees so since you know the value of d, you just do 180-70 to find e.

Answer:

a = 20°

b = 70°

c = 20°

d = 70°

e = 110°

Step-by-step explanation:

Angle A is complementary with 70°, so they add together to = 90° (as indicated by the 90° mark).

90° - 70° = 20°

Angle A = 20°

Angle B is complementary with angle A, 20°, so they also add together to = 90°.

90° - 20 = 70°

Angle B = 70°

Although not indicated by a 90° mark, Angle C and Angle B are complementary since they share a straight line with the complementary angles A and 70°. This means Angles C + B = 90°

90° - 70° = 20°

Angle C = 20°

Angle D is vertical to 70°, so Angle D = 70°

Angle E is supplementary to 70°, so they should combine to = 180°

180° - 70° = 110°

Angle E = 110°

It is False that the imaginary line which passes through the north and south poles, upon which the earth rotates once every 24 hours is called the prime meridian. .

In a geographic coordinate system, a prime meridian is any line of longitude when longitude is defined to be 0°. A great circle is formed by a prime meridian and its anti-meridian (the 180th meridian in a 360° system).

A spheroid, like the Earth, is divided into two hemispheres by this vast circle: the Eastern Hemisphere and the Western Hemisphere (for an east-west notational system).

Different conventions have been used or supported for Earth's prime meridian throughout history in various places. The IERS Reference Meridian is the current international prime meridian for the Earth. It is developed from the former Greenwich Meridian, however it is somewhat different.

126 three-digit numbers may be formed using elements from the set {1,2,3,4,5,6,7,8}. if no element may be used more than once in a number and the number must be even

For given question,

We need to find number of three-digit numbers formed using elements from the set {1,2,3,4,5,6,7,8}  if no element may be used more than once in a number and the number must be even.

3-digit even  numbers are to be formed using the given six digits,1 ,2,3,4,6,7, and 8 without repeating the digits.

Then, units digits can be filled in 4 ways by any of the digits, 2,4, 6 or 8.

Since the digits cannot be repeated in the 3-digit numbers and units place is already occupied with a digit (which is even), the hundreds and tens place is to be filled by the remaining 7 digits.

So, the number of ways in which hundreds and tens place can be filled with the remaining 7 digits is the permutation of 7 different digits taken 2 at a time.

[tex]\Rightarrow ~^7P_2=\frac{7!}{(7-2)!} \\\\\Rightarrow ~^7P_2=42[/tex]

Thus, by multiplication principle, the required number of 3-digit numbers is 3 × 42 = 126

The distance travelled by Charlotte in feet is 354 feet. This is obtained by using the concept of speed and distance on the given problem.

What is speed?

Speed is defined as the distance per unit of time. It is the numerical quantity that specifies how fast an object is moving. The basic unit of speed is given by m / s.

Calculation of the distance travelled by Charlotte in feet

Given:

Speed = 61.4 mi / h

Time = 3.93 s

The basic step to solve this problem is to convert miles per hour to feet per second

(61.4 mi / hr) * (5280 feet / mi) * (1 hr / 3600 sec) = 90.0533 feet / sec

Now, multiply the speed by the number of seconds to find the value of distance in feet

(90.0533 feet / sec) * (3.93 sec) = 353.909 feet.    

Hence, the distance travelled by Charlotte in feet is 354 feet.
