PLEASE HELP !!!!!!!!!!!!!!!!!2. Circle P has center P(2, 0) and radius 20. Circle Q has center Q(0, 4) and radius 2. (a) Describe the rule for translating center Q onto center P. (b) Determine the scale factor for dilating circle Q so that it has the same radius as circle P. (c) Are circles P and Q similar? Explain your answer.
Answers
Answer 1
Answer:
(a) Describe the rule for translating center Q onto center P. center P(2, 0) center Q(0, 4) you would need to add 2 units in x axis, and subtract 4 units on y axis.
(b) Determine the scale factor for dilating circle Q so that it has the same radius as circle P. P radius 20, Q radius 2, radiusQ*10 = radiusP, so the scale factor is 10
(c) Are circles P and Q similar? Explain your answer. they are similar because a similarity transformation (translation, dilation) exists between them
Solve each proportion: 4/15=x/75 and t/9=35/6 how do you work these please show steps thank you
Answers
multiplied by the cross
4/15 = x /75
15•x=4•75 15x=300 x= 300 : 15 x=20
t/9 = 35/6
9•35 = t•6 315 =6t 315 : 6 = t
52,5 = t
McDonald's sell milkshakes in two sizes a small milkshake contains 300ml and a large milkshake contains 2/3 more, how much does a large milkshake contain?
Answers
1/3 is 3/3 so 300/3 is 100 so 2/3 is 200 ml more so it holds 500 ml
75 to 45 simplest form
Answers
75 : 45 = 15 : 9 (divided both number by 5 ) = 5 : 3 ( divided both numbers by 3 )
hence, 5 : 3 is the simplest form of 75 : 45 Or you can write it in the fraction form = 5 / 3
75/45 in the simplest form is 5:3, 5 to 3, or 5/3
After John worked at a job for 10 years, his salary doubled. If he started at $x, his salary after 10 years is _____.$x $x + 2 $x - 2 $2x
Answers
The expression that would be best fit on the given statement would be 2x. This is because the question says that when John reached 10 years his salary will be doubled. Meaning the x salary will be times to 2, or simply 2x.
I think its $2x because if a variable is beside a number, it means you multiply.
Which is the standard form of the equation of a parabola with a focus of (8, 0) and directrix x = –8?
Answers
with a parabola that faces left or right it is (y-k)²=4p(x-h)
p is distance from directix to vertex which is also the distance from vertex to focus
if it opens to the right, then p is positive if it opens to the left, then p is negative
so we know that directix is-8 and focus is (8,0) directix is behind the parabola so therfor the parabola opens to the right distance from x=-8 to (8,0) is 16 units 16/2=8 p=8
vertex is 8 units to right of directix or 8 units to the left of focus (8,0) is focus so vertex is (0,0)
(h,k) is vertex (y-k)²=4p(x-h) (y-0)²=4(16)(x-0) y²=64x
Answer:
If your on e2020, its C
Step-by-step explanation:
y^2=32x, the work above is correct but they forgot to take the square away in the final answer. hope this helps!
