Point B has coordinates ​(2​,1​). The​ x-coordinate of point A is -10. The distance between point A and point B is 15 units. What are the possible coordinates of point​ A?

Answers

Answer 1

Answer:

(-10, 10) or (-10, -10)

Step-by-step explanation:

[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2[/tex]

[tex]15 = \sqrt{(-10 - 1)^2 + (y_2 -2 )^2}[/tex]

[tex]15 = \sqrt{121 + 2y + y^2 + 4}[/tex]

[tex](15)^{2} =( \sqrt{121 + 2y + y^2 + 4})^{2}[/tex]

[tex]225 = 121 + 2y + y^2 + 4[/tex]

[tex]225 = 125 + 2y + y^2[/tex]

[tex]0 = -100 + 2y + y^2[/tex]

[tex]0 = (y + 10)(y - 10)[/tex]

Alfonso plans to create an ice sculpture out of a 8-cubic foot ice cube. What is the surface area of the cube?

Answers

Answer:

Surface area of cube = 24 ft²

Step-by-step explanation:

Given:

Volume of cube = 8 ft³

Find:

Surface area of cube

Computation:

Volume of cube = Side³

Side³ = 8 ft³

Side³ = (2 ft)³

Side = 2 ft

Surface area of cube = 6a²

Surface area of cube = 6(2)²

Surface area of cube = 6(4)

Surface area of cube = 24 ft²

The area of a rectangle is 560 square inches. The length is 3 more twice the width. Find the length and width.

Answers

Answer:

l = 35 inches and b = 16 inches

Step-by-step explanation:

Let length be b and width be b.

The area of a rectangle is 560 square inches.

Length is 3 more twice the width.

l = 2b+3 ....(1)

We know that,

Area = length × width

560 = (2b+3)b

[tex]2b^2+3b-560=0\\\\b=16,-17.5[/tex]

Put b = 16 in equation (1).

l = 2(16)+3

= 35 inches

So, the length is 35 inches and the width is 16 inches.

Answer:

60

Step-by-step explanation:

In order to get this answer, we must know that a triangle's angles add up to exactly 180. Also, Angles that intersect will have congruent, opposite sides. The last thing is that a line is = 180 degrees. So, the triangle with the 94 and the 142, you can use that. the angle next to the 142 is going to be 180-142 which is 38 and since the other angle is opposite 94, as well. when you add those up u get 132 and 180-132= 48 which is the missing angle for the far right triangle. then, you get the opposite of that angle, put that in the other triangle, do the same with the 72, and add those up to get 120 and since a triagle adds up to 180, 180-120 = 60. So, 60 is your missing angle. Cheers

The manager of The Counter noticed that the birthday club members all brought along a family member who spent an average of $22.00 in the restaurant. The tax on their bill was 9 percent. How much did the family member pay in total? (Hint: bill total + tax)

Answers

Answer:

Total amount pay by family member = $23.98

Step-by-step explanation:

Given:

Average amount spent on food = $22

Tax rate on restaurant food = 9%

Find:

Total amount pay by family member

Computation:

Amount of tax pay by family member = Average amount spent on food x Tax rate on restaurant food

Amount of tax pay by family member = 22 x 9%

Amount of tax pay by family member = 22 x 0.09

Amount of tax pay by family member = $1.98

Total amount pay by family member = Average amount spent on food + Amount of tax pay by family member

Total amount pay by family member = 22 + 1.98

Total amount pay by family member = $23.98

h(0) = 0^2 - 3

h(0) = -3
