Given a=33 and c=44,

b = 29.10326 = 11√7

Step-by-step explanation:

The following is one way to perform the calculation. It may not be the best way.

b =√c2 - a2

=√442 - 332

=√847

=29.10326 = 11√7

∠α =arcsin(a/c)

=arcsin(33/44)

=arcsin(0.75)

=0.84806 rad = 48.59° = 48°35'25"

∠β =arcsin(b/c )

c

=arcsin(29.10326442171/44)

arcsin(0.66143782776615)

=0.72273 rad = 41.41° = 41°24'35"

h =a×b/c

=33 × 29.10326442171/44

=21.82745

area =a×b/2

=33 × 29.10326442171/2

=480.20386=363√7/2

perimeter =a+b+c

=33 + 29.10326442171 + 44

=106.10326

inradius =a×b/a+b+c

=960.40772591645/106.10326442171

=9.05163

circumradius =c/2

=44/2

=22

Radius from the center is perpendicular to the tangent.

In quadrilateral ABCO,

∠ABC+∠BCO+∠AOC+∠OAB=360°

30°+90°+∠AOC+90°=360°

∠AOC+210°=360°

∠AOC=360°-210°

∠AOC=150°

Hence, arc AC=150°

Step-by-step explanation:

For a parabola y = ax² + bx + c, the vertex occurs at x = -b / (2a).

For f(x), a = -2, b = 0, and c = 9.  So the vertex is at:

x = -0 / (2×-2)

x = 0

At x=0:

f(0) = -2(0)² + 9

f(0) = 9

The maximum of g(x) is at 11.

So g(x) has a greater maximum value than f(x).

To find this product, multiply each of the 6 numbers in the given matrix by 6.  The third possible answer choice is the correct one.

Answer:

(A) 180

Step-by-step explanation:

We have to treat those player selections as independent events, since one doesn't influence the other (the fact you chose Joe as a guard, shouldn't have an influence on who'll pick as center, unless there's bad blood between some players... but that's a whole other story).

So, how many ways to pick 2 guards from a selection of 4?  The order doesn't seem to matter here, since they don't specify for example that Joe can only play on the left side).  So, it's a pure combination calculation:

[tex]C(4,2) = \frac{4!}{2! * (4 - 2)!} = \frac{24}{2 * 2} = 6[/tex]

C(4,2) = 6.

How many ways to pick the 2 forwards from a group of 5?  Using the same calculation, we get:

C(5,2) = 10.

And of course, the coach has 3 ways to pick a center player from 3.

Then we multiply the possible ways to pick guards, forwards and center...

6 * 10 * 3 = 180 ways.

Answer:

1.  unimodal

2. bimodal

3. skewed right

4. skewed left

5. uniform

6. random

Step-by-step explanation:

Answer:

1) Uni-modal 2) Bi-modal 3) Skewed right 4) Skewed left 5) Uniform 6) Random  

Step-by-step explanation:

We are given the following information in the question:

1) Since we can see in the graph, there is one observation with highest frequency. Thus, this graph represents a uni-modal data

2) It s clearly seen that there are two values with highest frequencies. These two observations can be treated as the mode of the data. Thus, there are two modes. Thus, the graph represents a bi-modal data.

3) We can see that most of the data lies on the left side of data and very less data is there on the left tail. Hence, the graph is positively skewed or skewed on the right.

4) We can see that most of the data lies on the right side of data and very less data is there on the right tail. Hence, the graph is negatively skewed or skewed on the left.

5. Since all the observations are very close to each other almost equal we could say that the data have a uniform distribution.

6. The above data set have a random distribution since no pattern are observed.

If we want to share the money in equal parts, we have to consider that Eli has 9 shares, Freda has 13 shares and Geoff has 18 shares. So, in total, we have to split the money in

[tex]9+13+18 = 40[/tex]

parts. So, each part is

[tex]\dfrac{800}{40} = \dfrac{80}{4} = 20[/tex]£

Now, we distribute the shares:

Answer:

Eli gets £180

Freda gets £260

Geoff gets £360

Step-by-step explanation:

First, you need to make a ratio comparing their ages.

9 : 13 : 18 which is Eli : Freda : Geoff

Next, you need to work out the sum their ages (9+13+18) which is 40.

Then you divide the £800 (the amount that is being shared) by the sum of their ages 800÷40 which gives £20.And finally you need to multiply 20 by each section of the ratio.

So, 9×20 : 13×20 : 18 ×20 but then you need to simplify to get 180: 260 : 360.

Answer:

The statement which not true is (A)

Step-by-step explanation:

* At first lets revise the volume of the cone and the cylinder

- The cone has circular base and one vertex

- Its height is the line joining the vertex and the center of the base

- Its volume is 1/3(BH), where B is the area of its base and H is its height

- The cylinder has two circular bases

- Its height the line joining between the centers of the two bases

- Its volume = BH, where B is the area of its base and H is its height

* Now lets solve the problem

- The ice cream cup is shaped cylinder with diameter 3 inches

  and height 3 inches

- The ice ream cone is shaped a cone with diameter 4 inches

  and height 6 inches

* Lets find the volume of the ice cream cup

- The volume of the ice cream cup = BH

∵ B = πr² ⇒ area the circle

∵ Its diameter is 3 inches

∵ The radius = 1/2 the diameter

∴ r = 3 × 1/2 = 1.5 inches

∴ B = π(1.5)² = 2.25π inches²

∵ H = 3 inches

∴ V = 2.25 × 3 = 6.75π inches³

* Lets find the volume of the ice cream cone

- The volume of the ice cream cone =1/3 BH

∵ B = πr² ⇒ area the circle

∵ Its diameter is 4 inches

∵ The radius = 1/2 the diameter

∴ r = 4 × 1/2 = 2 inches

∴ B = π(2)² = 4π inches²

∵ H = 6 inches

∴ V = 1/3 × 4π × 6 = 8π inches³

* Lets find the right answer

# (A)

∵ The volume of 24-pack of ice ream cups = 24 × 6.75π = 162π inches³

∵ The volume of 21-pack of ice ream cones = 21 × 8π = 168π inches³

∵ 162π < 168π

∴ (A) Not true

# (B)

∵ The volume of 12-pack of ice ream cups = 12 × 6.75π = 254.5 inches³

∵ 254.5 inches³ > 250 inches³

∴ (B) is true

# (C)

∵ The volume of 14-pack of ice ream cons = 14 × 8π = 351.9 inches³

∵ 351.9 inches³ > 350 inches³

∴ (C) is true

# (D)

∵ The volume of 12-pack of ice ream cups = 12 × 6.75π = 81π inches³

∵ The cylinder container has height = 8 inches

∵ The cylinder container had diameter = 6 inches

∴ its raduis = 1/2 × 6 = 3

∵ The volume of the cylinder container = BH

∵ B = πr² = π(3)² = 9π

∴ Its volume = 9π × 8 = 72π

∵ 81π > 72π

∴ (D) is true

* The statement which not true is (A)

[tex]\frac{2}{5}=0.400[/tex]

[tex]\frac{1}{4}=0.250[/tex]

[tex]\frac{3}{8}=0.375[/tex]

So the correct order from least to greatest should be

0.250, 0.375, 0.400

Which corresponds in fractional form to

1/4, 3/8, 2/5

So the correct option is

C) 1/4,3/8,2/5

The correct set of fractions ordered from least to greatest is C) 1/4, 3/8, 2/5.

To determine the set of fractions ordered from least to greatest, we need to compare them by finding a common denominator or converting them to decimals.

Let's convert the fractions to decimals:

Next, we order the decimals from smallest to largest:

Therefore, the correct order from least to greatest is: C) 1/4, 3/8, 2/5.

Answer:

Snowboard can be purchased for the lowest price from Store C offering 40% discount.

Step-by-step explanation:

We need to compare discounts of 3 stores and find the store selling snowboard lowest of them.

Store A: Sale of 30% off and a successive discount of 10% off.

The formula used for successive discount is = (x+y - xy /100)%

here x= 30 and y =10 so total discount is:

Total discount = ( 30 +10 - (30*10)/100)%

                       = (40 - 300/100) %

                       = (40 -3) % = 37%

Original price = $189.59

Discount offered = 37% of $189.59

                            = 37/100 * 189.59 = $70.15

Selling Price = Original price - Discount offered

                     = $189.59 - $70.15

                     = $ 119.44

Store B: Sale of 20% off and a successive discount of 20% off.

The formula used for successive discount is = (x+y - xy /100)%

here x= 20 and y =20 so total discount is:

Total discount = ( 20 +20 - (20*20)/100)%

                       = (40 - 400/100) %

                       = (40 -4) % = 36%

Original price = $189.59

Discount offered = 36% of $189.59

                            = 36/100 * 189.59 = $68.25

Selling Price = Original price - Discount offered

                     = $189.59 - $68.25

                    = $ 121.34

Store C: Sale of 40% off.

Original price = $189.59

Discount offered = 40% of $189.59

                            = 40/100 * 189.59 = $75.84

Selling Price = Original price - Discount offered

                     = $189.59 - $75.84

                    = $ 113.75

So, Store A Sale price is: $ 119.44

Store B Sale price is: $ 121.34

and Store C Sale price is: $ 113.75

So, Comparing them we found that snowboard can be purchased for the lowest price from Store C offering 40% discount.

• If c > 0 then translation up of + c units

• If c < 0 then translation down of - c units

Hence

g(x) = f(x) - 7

then g(x) is the graph of f(x) shifted 7 units down → B

No diagram and no explanation what 9 is.

However, if it is an octagon with each side equal to 9 then

area = (# of sides * side^2) / (4 * tan (180 # of sides))

area = 8 * 9 * 9 / (4* tan (180 / 8)

area = 648 / 4 * 0.41421

area = 391.1059607446

answer is C

Step-by-step explanation:

The area of the considered octagon which has distance from its center to the vertex of 9 m is given by: Option b). 229.1 m²

If the regular octagon has sides of 'a' units, then its area is:

[tex]A = 2(1+\sqrt{2})a^2 \: \rm unit^2[/tex]

Consider the attached figure below (second figure too).

If we find the value of 'a', then we can use the above formula.

Since there are 8 equal sides in a regular octagon, the angle from center to each of the side is full angle / 8 = 360/8 = 45 degrees.

Since the angle OA is perpendicular on BC, due to symmetry, we have the angle BOC divided into 2 parts.

Thus, we get:

m∠AOB = 45/2 degrees = 22.5°

Using the sine ratio from the perspective of angle AOB, we get:

[tex]\sin(m\angle AOB) = \dfrac{|AB|}{|OB|}\\\\\sin(22.5^\circ) = \dfrac{a/2}{9}\\\\a \approx 2 \times 9 \times 0.38268 \approx 6.888[/tex] meters

(since length of AB is half of length of BC, which is 'a' units).

Thus, we get:

[tex]A = 2(1+\sqrt{2})a^2 \approx 2(1+\sqrt{2})(6.888)^2 \approx 229.1\: \rm m^2[/tex]

Thus, the area of the considered octagon which has distance from its center to the vertex of 9 m is given by: Option b). 229.1 m²

Final answer:

You can use a number line to find the sum of -8.3 + 10.5 by marking both numbers on the line, moving left to the negative value, and then moving right by the positive value to find the sum.

Explanation:

To find the sum of -8.3 and 10.5 using a number line, you start by drawing a horizontal line and marking the positions of -8.3 and +10.5 on it. You then move from 0 to -8.3 as this is a negative number. To add 10.5, you move 10.5 units to the right. Because 10.5 is greater than 8.3, your final position will be to the right of zero which makes the sum positive.

Let's break down the steps:

Draw a number line with enough space to mark both -8.3 and +10.5.

Mark the point -8.3 on the left side of zero since it's a negative number.

From -8.3, move 10.5 units to the right because you are adding a positive number.

The point you land on is the sum of -8.3 + 10.5.

If you need to subtract numbers, change the sign of the number being subtracted and then add according to the rules of addition. For instance, to subtract 3 from 5, you would change 3 to -3 and then add: 5 + (-3) = 2.

9x^(3/2)=9 √(x^3 )  

Step-by-step explanation:

We are given

9x^(3/2)

We have to write the expression in radical form, for that the power has to be a multiple of ½

=9x^(3*1/2)

As we can see now the power is a multiple of 1/2. ½ will convert to square root while 3 will become the power of radicand.

So, 9 will remain outside of the square root while x will be inside the square root while having power 3.

=9 √(x^3 )

Hence,
