What is the simplest form of the product? SqRt 63x^5y^3 - 1

Answers

Answer 1
Answer: √(63x^5y^3) \cdot √( 14xy^8 )=\n \n=√(63x^5y^3\cdot 14xy^8 )=\n \n\sqrt{882x^(5+1) y^3 y^8 } =\n \n=√(441 \cdot 2 \cdot x^6y^3y^8)=\n \n=√(441) \cdot √(y^8)\cdot \sqrt{x^(6) }\cdot √(2y^3) = \n \n=21 \cdot( y ^(8 ))^(1)/(2)\cdot ( x^6)^{(1)/(2)}*\sqrt{2y^(3)}\n \n=21 \cdot x^3 \cdot y^4 \cdot √(2y^3)
Answer 2
Answer: √(63x^5y^3)\cdot√(14xy^8)=√(63x^5y^3\cdot14xy^8)=\sqrt{63\cdot14\cdot x^(5+1)y^(3+8)}\n\n=\sqrt{9\cdot7\cdot7\cdot2\cdot x^6y^(11)}=\sqrt9\cdot√(7^2)\cdot√(2)\cdot√(x^6)\cdot\sqrt{y^(11)}\n\n=3\cdot7\cdot\sqrt2\cdot√((x^3)^2)\cdot\sqrt{y^(10)\cdot y}=21\sqrt2\cdot x^3\cdot√((y^5)^2)\cdot√(y)\n\n=21x^3y^5√(2y)

Which expression can be used to convert 22 Australian dollars to US dollars assume 1.2 Australian dollar equals to US dollars

Answers

1 USD = 1.2 AUD, therefore you get the AUD if you multiply the USD by 1.2. You need the other way around, so AUD/1.2 = USD.

Can you please solve this for me.

Answers

Answer:

h = 5

Step-by-step explanation:

One place to look to find the difference between f(x) and g(x) is the y-axis. The y-intercept of g(x) is 5. The y-intercept of f(x) is 0. Then you have ...

... g(0) = f(0) +h

... 5 = 0 +h . . . . put in the values you read from the graph

... 5 = h

Karen and Daryl work for a delivery service. Karen made 15 more deliveries than Daryl. If Daryl made d deliveries, which expression represents the number of deliveries Karen made?a. d divided by 15B. 15 + dC. 15 • dD. d- 15

Answers

Given : Karen and Daryl work for a delivery service.Karen made 15 more deliveries than Daryl. Let d be the deliveries made by Daryl .We need to find the expression that represents the number of deliveries Karen made

Karen made 15 more deliveries than Daryl. The mathematical symbol for more than is addition or + sign .

15 more than d can be represented by 15+d.

Option B. 15 + d is the right answer.
The answer is B 15+d

Find the surface area of the prism.A.

Hey,

ok so the area of a rectangle is the product of the two sides. One side is the height of the can, the other side is the perimeter of the circle, since the label wraps once around the can. So the area of the rectangle is (2 pi r)* h. Add those two parts together and you have the formula for the surface area of a cylinder.

so To find the surface area, first multiply the length by the width to find the area. Since a cube is made up of six perfect squares, multiply the are aby six. That each measure four. Plug four into the formula to find the surface area

So the formula would be SA=2(LW+LH+WH

so area a^2+4=98^

So it is C 

h
ok
prism so 3 pairs of congruent sides thtat are oposite of each other
areas of each are
LW, WH, LH
(L=legnth,W=width,H=height and LW means L times W)

come in pairs
SA=2LW+2WH+2LH
undsitribue for ease
SA=2(LW+WH+LH)

L=4
W=3
H=5
sub
SA=2(4*3+3*5+4*5(
SA=2(12+15+20)
SA=2(47)
SA=94 cm^2

answer is C
