Answer:

solution given :

centre (h,k)=(3,-2)

another point (a,b)=(4,-6)

now

radius =[tex] \sqrt{(3-4)²+(-2+6)²} [/tex]=√17

We have

equation of a circle is:

C. 2.

Answer:

C

Step-by-step explanation:

When multiplying scalars and matrices, just distribute the scalar to every component of the matrix. So 4*6=24, -2*6= -12, 6*6 = 36, 7*6 = 42, 3*6 = 18, and 0*6 = 0.

===============================================

Explanation:

We're told that

cos(B) = 9/41

Since the cosine ratio involves adjacent/hypotenuse, we can see that the adjacent side is 9 and the hypotenuse is 41. For angle B, the adjacent side is the leg closest to the angle in question. So that would be side AB.

Therefore, AB = 9 and BC = 41 are the adjacent and hypotenuse for reference angle B.

Apply the pythagorean theorem to solve 9^2+x^2 = 41^2, and you should get x = 40. This is the other leg of the triangle. Or you could note how tan(C) = 9/40 to imply that AC = 40 is the adjacent side for reference angle C.

Answer:

r = 9

Step-by-step explanation:

[tex] In\: \odot O, [/tex] QP is tangent at point P and OP is radius.

[tex] \therefore OP\perp QP[/tex]

[tex] \therefore m\angle OPQ = 90\degree [/tex]

So, [tex] \triangle OPQ[/tex] is a right angled triangle. Hence, OQ will be its HYPOTENUSE such that OQ = r + 32

Now, by Pythagoras theorem:

[tex] OQ^2 = OP^2 + PQ^2 [/tex]

[tex] \therefore (r + 32)^2 = r^2 + (40)^2 [/tex]

[tex] \therefore\cancel {r^2} + 64r + 1024 = \cancel {r^2} + 1600 [/tex]

[tex] \therefore 64r = 1600-1024 [/tex]

[tex] \therefore 64r = 576 [/tex]

[tex] \therefore r = \frac{576}{64}[/tex]

[tex] \therefore r = 9[/tex]

I did the work, and basically i solved for the area of the faces and then multiplied that by two to get the total surface area of the faces. Then I added in the areas of the sides connecting the two faces:

just as a referral: the formulas to find the faces are as follows:

rectangle: length times width

circle: pi x r^2

trapezoid: h(base1 + base2)

and triangle: (b x h)/2

Answer:

the answer is 1/4

Step-by-step explanation:

2/5 × 5/8

2× 5/ 5 × 8

= 10/40

=1/4

Answer:

1/4

Step-by-step explanation:

You would do 2/5 times 5/8 which would equal 10/40 cause 5 times 2 is 10 and then 5 times 8 is 40 and then you would simplify the fraction 10/40 which would make it 1/4

Answer:

The answer is 9.0909

Step-by-step explanation:

n=1  p=.11

mean = 1/0.11 = 9.0909

The mean of X, the number of patients seen until an injection-site reaction occurs is 9.0909.

The mean refers to "the average set of values".

According to the question,

The percentage of patients experiencing injection- site reactions with the current needle is 11%.

Mean = [tex]\frac{sum of the all values}{Total number of values}[/tex]

Total number of values = 11% = 0.11 and  n = 1.

Mean = [tex]\frac{1}{0.11}[/tex]

=9.0909.

Hence, the mean of X, the number of patients seen until an injection-site reaction occurs is 9.0909.

Answer: 541.32 miles

Step-by-step explanation:

First find the speed of the train in miles per hour.

1 hour 20 minutes needs to be converted to decimal:

= 1 20/60

= 80/60

= 1.33 hours

Speed is:

= Distance / Time

= 120/ 1.33

= 90.22 miles an hour

If the train is traveling 6 hours at the above speed, it will travel:

= Speed * time

= 90.22 * 6

= 541.32 miles

Answer:

AH = [tex]\sqrt{51}[/tex]

Step-by-step explanation:

The opposite sides of a rectangle are congruent , so

GH = RA = 7

Using Pythagoras' identity in right Δ GHA

AH² + GH² = GA²

AH² + 7² = 10²

AH² + 49 = 100 ( subtract 49 from both sides )

AH² = 51 ( take the square root of both sides )

AH = [tex]\sqrt{51}[/tex] ≈ 7.14 ( to 2 dec. places )

Answer:

√51 (or in LaTeX $sqrt51$)

Step-by-step explanation:

We know that Triangle GRA is a right triangle because Angle GRA is one of the angles of rectangle GRAH, and all interior angles of a rectangle are right.

We also know the lengths of two sides of GRA, so we can use the Pythagorean Theorem to solve for the third side. Specifically, the Pythagorean Theorem tells us that

(GR)^2 + (RA)^2 = (GA)^2.Plugging in RA=7 and GA=10, we get

(GR)^2 + 49 = 100,so (GR)^2=51. We know that GR is positive, so we conclude that $GR=\sqrt{51}$. Finally, since GRAH is a rectangle, its opposite sides have equal length. Thus AH = GR, and so AH = √51, which cannot be simplified.

Answer:

4.2

Step-by-step explanation

Delta

The area of the triangle STU to the nearest of a square centimeter is 4.2 cm².

area of the triangle = 1 / 2 tu sin S

where

Therefore,

t = 3.4 cm

u = 6.9 cm

∠S = 21°

Hence,

area of the triangle = 1 / 2 × 3.4 × 6.9 sin 21°

area of the triangle = 23.46 sin 21 / 2

area of the triangle = 23.46 × 0.35836794954 / 2

area of the triangle = 8.40731209633 / 2

area of the triangle = 4.20365604817

area of the triangle = 4.2 cm²

To find his average, we will find the mean. This means we will add 220+166+181 to get 567. When finding the mean we divide the answer but the total amount of addends. In our case we have 3 so we divide 567 by 3.

567 divided by 3 = 189
