The ordered pairs (1, 81), (2, 100), (3, 121), (4, 144), and (5, 169) represent a function. What is a rule that represents this function? A. y = x 8 B. y = 8x C. y = (x + 8)2 D. y = 8x
Find the dimensions of a rectangle whose perimeter is 26 meters and whose area is 40 square meters.
Answers
The rectangle is 8 metres by 5 metres.
You find the two numbers which can multiply to make 40 and see which of those also would result in a perimeter of 26. To make 40 you can have 4 and 10, 2 and 20, 1 and 40, or 8 and 5. 8 and 5 are the only lengths which give a perimeter of 26.
1. What is the volume of the prism that can be constructed from this net? 2. What is the volume of this figure? 3. What is the volume of this figure? 4. What is the volume of the prism that can be constructed from this net?
Answers
1. V = lwh V = (8)(4)(5) V = (32)(5) V = 160 units³
2. V = lwh + lwh V = (4)(2)(1) + (3)(1)(1) V = (8)(1) + (3)(1) V = 8 + 3 V = 11 units³
3. V = leh + s³ V = (9)(3)(4) + (3)³ V = (27)(4) + 27 V = 108 + 27 V = 135 units³
4. V = lwh V = (3)(7)(2) V = (21)(2) V = 42 units³
jane walked 4/5 mile on monday on tesday she wwalked 1//2 of the distance she walked on monday how many miles she walked on tuesday a 3/4 mile b 2/5 mile c 1/5 mile d 1/2 mile
Answers
4/5 on mon tue=1/2 of mon (4/5)
so 1/2 of 4/5 'of' can be translated to multiply with fractions 1/2 times 4/5=(1 times 4)/(2 times 5)=4/10=2/5
the naswer is 2/5 mile or b
I got B i turned them into decimals 4/5 is 0.8 1/2 is 0.5 0.8*0.5=0.4 0.4=2/5
A circle has a diameter with endpoints of (2, -8) and (6, 4). What is the center of the circle?
Answers
The length of the diameter is (4,12) The center is (4, -2)
Diameter = √(y2-y1)² + (x2 - x1)² d = √(4-(-8))² + (6-2)² d = √12² + 4² d = √144 + 16 d = √160
In short, Your Answer would be √160 or 12.65
Hope this helps!

Write 6y = x + 5 in standard form using integers. A. –x + 6y = 5 B. –6x + 6y = 30 C. -6x - 6y = 30 D. 6x - 6y = 30
Answers
I hope this helps you
-x+6y=5
Standard form is Ax+By=C, so with that knowledge, we can work with the problem to get it how we want it!
Our first step is to get x and y on the same side of the equals sign. To do that, we can subtract an x from both sides, turning 6y = x + 5 into -x +6y = 5. Lucky for us, this brings us straight to the answer, which is A) -x +6y = 5!
