Answer:

Step-by-step explanation:

(A)From the given figure, we have

arc AC=(4x+17)° and ∠ABC=(4x-3.5)°

From the properties of chords in circle, we know

∠ABC=\frac{1}{2}arcAC

⇒4x-3.5=\frac{1}{2}(4x+17)

⇒8x-7.0=4x+17

⇒4x=24

⇒x=6

Therefore, ∠ABC=(4x-3.5)°=4(6)-3.5=24-3.5=20.5° and arcAC=4x+17=4(6)+17=24+17=41°.

(B) It is given that CO is congruent to the segment HZ.

We know that In a circle, if two chords are equal in measure, then their corresponding minor arcs are equal in measure.

Therefore, if CO is congruent to HZ, then arc CO is congruent to arc HZ, hence option D is correct.

Three answer choices have the same quotient as 4.55 ÷ 0.7. Which one does NOT
Masteriza [31]

Answer:

Answer: 455 / 7

Step-by-step explanation: Three answer choices have the same quotient as 4.55 ÷ 0.7. Which one does NOT?

answer choices

455 ÷ 70

455 ÷ 7

45.5 ÷ 7

4.55 ÷ 0.70

The number resulting from the division of one number by another is regarded as quotient. For example, The quotient of 12 divided by 4 is 3.

And so, the first, third and last options on expansion by division all yield the same results in decimals (6.5) as that in the question (4.55 / 0.7 = 6.5) which is an indication that they have the same quotient.

Only the second option does not do so. 455 / 70 = 65

Find the point on the terminal side of θ = 3pi/4 that has a y coordinate of 1. Show your work for full credit.
bagirrra123 [75]
Ok, we know the angle is 3π/4, and that y-coordinate is 1, hmm what's "x"?

\bf tan(\theta)=\cfrac{y}{x}\qquad tan\left( \frac{3\pi }{4} \right)=\cfrac{1}{x}\implies \cfrac{sin\left( \frac{3\pi }{4} \right)}{cos\left( \frac{3\pi }{4} \right)}=\cfrac{1}{x}\implies \cfrac{\frac{\sqrt{2}}{2}}{-\frac{\sqrt{2}}{2}}=\cfrac{1}{x}
\\\\\\
-1=\cfrac{1}{x}\implies x=-1\qquad \qquad \boxed{(-1,1)}

Type the correct answer in the box use nummerals instead of words. if necessary use / for the faction bar
zzz [600]

Answer: f(y) x g(y) = 1

Step-by-step explanation:

\frac{2y^3-y^2+2y-1}{y^3-y^2+y-1}\cdot \frac{2y^2-3y+1}{4y^2-4y+1}\\\\= \frac{4y^5-8y^4+9y^3-9y^2+5y-1}{4y^5-8y^4+9y^3-9y^2+5y-1} \\\\= \frac{(y-1)(2y-1)(2y-1)(y^2+1)}{(y-1)(2y-1)(2y-1)(y^2+1)} \\\\= 1

So that you're coming purpose of each circle and find the radius and diameter below the circle
oksano4ka [1.4K]

Answer:

1.

The radius is given, so the radius is = 10

The radius is doubled to be a diameter, so (10 + 10) = 20 is your diameter

And to solve for circumference, your formula is;

C = 2πr

Where 'r' represents the radius, and 'π'(pi) is 22/7 or 3.14.

Plug in your values:-

C = 2πr

C = 2(3.14) x 10

C = 6.28 x 10

C = 62.8, so your circumference is 62.8.

2.

Your radius is half of your diameter, so,

D/2 = R

D = diameter

R = Radius

49/2 = 24.5 is your radius.

Your diameter is given, so the diameter is 49.

Use the formula we applied for circumference in our other problem;

C = 2πr

C = 2(3.14) x 24.5

C = 6.28 x 24.5

C = 153.86, so 153.86 is your circumference.
