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.

4|w − 5| = 4
anastassius [24]

Answer:

   w = 9 or  w = 1

Step-by-step explanation:

4|w − 5| = 4

Divide both sides by 4

w - 5 = 4                         w - 5 = -4

   + 5    + 5                          + 5     + 5

     w = 9                             w = 1

Pleaase help!<br>Find h. 11 in. h = ✓ [?] in. 14 in Enter​
Aleksandr [31]

Answer:

h=8.48\ \text{inches}

Step-by-step explanation:

Given that,

Radius of cone, r = 7 inches

Slant height of the cone, l = 11 inches

We need to find the height of the cone. Let the height be h. Using trigonometry to find it as follows :

h^2+r^2=l^2\\\\h=\sqrt{l^2-r^2}\\\\h=\sqrt{11^2-7^2}\\\\h=8.48\ \text{inches}

So, the height of the cone is equal to 8.48\ \text{inches}.

Explain why (4, 1) is not the solution to the equation= 3x+1.
Katarina [22]
Keep in mind that a coordinate is in the form (x, y), so if you plug those values into the equation y=3x+1, you get 1=3(4)+1, simplified to 1=13, which is an untrue statement. However, I'm assuming you mean that the value of y is 4 and x is 1, which would be written as (1, 4). This would be the solution to this equation because 4=3(1)+1 is 4=4 which is a true statement.

What number should come next ?
babymother [125]
<h2>Answer: <u>The number that comes next is 52 </u></h2>

Step-by-step explanation:

2 + (1^2 - 1 ) = 2

2 +( 2^2 - 1 ) = 5

5 + ( 3^2 - 1) = 28

28 + (5^2 - 1) = 52

Thus the next number would be 52

Hope this helps :D
