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

Alexis is knitting a blanket 2 meters long. Every 2 decimeters, she changes the color of the yarn to make stripes. How many stri

Aliun [14]

Answer:

There are 10 stripes in the blanket.

Step-by-step explanation:

We are given the following in the question:

Length of blanket = 2 meters

1 meter = 10 decimeter

Length of blanket in decimeter =

$2\times 10 = 20\text{ decimeters}$

Change of color = Every 2 decimeters.

Number of stripe =

$=\dfrac{\text{Length of blanket}}{\text{Length of change of color of stripe}}\\\\=\dfrac{20}{2} = 10$

Thus, there are 10 stripes in the blanket.

The solution to the inequality |x + 3| - 2 < 0 is -5 < x < -1 as shown in the graph attached

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more variables and numbers.

Inequality is an expression used to show the non equal comparison of two or more numbers and variables.

Given that:

|x + 3| - 2 < 0

Hence:

(x + 3) - 2 < 0 and -(x + 3) - 2 < 0

x < -1 and x > -5

The solution to the inequality |x + 3| - 2 < 0 is -5 < x < -1 as shown in the graph attached
