Q(–1, a) is 4 5 units away from P(3, –2). Find all possible values of a
Natali [406]

Answer:

Step-by-step explanation:

Using the formula for calculating the distance between 2 points.

D = √(x2-x1)²+(y2-y1)²

Given

D = 45 units

The coordinates Q(–1, a) and P(3,2)

45 = √(3-(-1))²+(-2-a)²

45 = √4²+(-2-a)²

45 = √16+(-2-a)²

45² = 16+(-2-a)²

45² = 16+4+4a+a²

45² = 20+4a+a²

a²-4a+20-2025 = 0

a²+4a-2005 = 0

a = -4±√16+4(2005)/2

a = -4±√16+8020/2

a = -4±√8036/2

a =  -4±90/2

a = -4+90/2

a = 86/2

a = 43

The possible values of a is 43

(HELP ME!!!!!!!!!!!!)
Kobotan [32]

The car is driving at 70 miles per hour which is above the speed limit on the highway

<h3 /><h3>Linear equation</h3>

A linear equation is in the form:

y = mx + b

where y, x are variables, m is the slope of the line and m is the y intercept.

Let y represent the distance in miles and x represent the time in hours. Hence:

  • Using the points (0, 0) and (3, 200)

Slope = \frac{y_2-y_1}{x_2-x_1} =\frac{200-0}{3-0} =66.7

Bob speed limit is 66.7 miles per hour

Given a car by y = 70x. The car is driving at 70 miles per hour which is above the speed limit on the highway

sertanlavr [38]

If at the end of the study, the sociologist had a sample of 500 expectant parents and he estimates that there are 6 million expectant parents in the United States then the value of n is 500.

Given that the sample size is 500 and the number of expectant parents be 6 million.

We are required to find what n represents and value of n.

The value of n is 500. Small n shows the sample size and capital N shows the size of population.

Sample is that part of the population that represents the characteristics of the whole population.

Population is the number of individuals present in the area which a researcher wants to observe.

Hence if at the end of the study, the sociologist had a sample of 500 expectant parents and he estimates that there are 6 million expectant parents in the United States then the value of n is 500.
