ANSWER: D

Isosceles Right Triangle has 3 angles: 90 degrees, 45 degrees and 45 degrees

Answer:

D

Step-by-step explanation:

It is isosceles (having two sides and angles congruent) and it is right will provide enough information to find all the angles of the triangles.

Answer:

so 1/4 of a circle is 90 degrees 1/4 is equal to 90 over 360 C it's 90 parts of 360. so here we go with this one. this angle is 20 degrees remember that's 90 alright the square one and this little part would be 20 degrees each angle appears wider as the Rays get longer.

Answer:

25%

Step-by-step explanation:

I'm not great at probability but the chances of rolling an odd number on one dice is 50%, so you should have to multiply 0.5 * 0.5 to get 0.25, or a percentage of 25%. Hope this helps :)

Answer:

the time is 1.57 sec and the distance is 49.32mm

Step-by-step explanation:

Given that,

The angle is 180°

Angular velocity is 2rev/sec

The radius is 10mm

we are to find the time and distance traveled at that time

The formula is

θ = at

where t is the time,

a is the angular velocity

θ is angle in radian

so,

θ = 180° × π/180°

θ = π

= 3.14

Hence ,

θ = at

3.14 = 2t

t = 1.57sec

let the distance be xmm

[tex]\frac{1.57 \times 180^0}{360} = \frac{x}{20 \pi} \\\\0.785 = \frac{x}{20 \pi} \\\\x = 49.32mm[/tex]

Therefore , the time is 1.57 sec and the distance is 49.32mm

Answer:

a) 0.25 s

b) 15.71 mm

Step-by-step explanation:

Given:-

- The radius of the coin, r = 10 mm

- The angle swept by the coin, θ = 180°

- The frequency of ration of the coin, f = 2 rev /s

Find:-

How long will it take the coin to roll through the given angle measure at the

given angular velocity?

How far will it travel in that time?

Solution:-

- We will first determine the angular speed ( ω ) of the coin. That is the rate of change of angle swept. Mathematically expressed as:

                       ω = dθ / dt = 2*π*f

- Separate the variables:

                      dθ = 2*π*f . dt

- Integrate both sides.

                      ∫dθ = 2*π*f ∫ dt

                      θ = 2*π*f*t

- The time taken to sweep an angle of ( θ ) is:

                      t = θ / 2*π*f

Where, θ is in radians. 180° = π radians

- Plug in the values:

                      t = π / 2*π*( 2 )

                      t = 1 / 4 = 0.25 s   ... Answer

- The tangential speed (v) of any point on the circumference of a coin is. Considering only rolling motion of the coin:

                    v = r*ω = 2*r*π*f

- The velocity of the any point on the rolling coin circumference would be:

                   v = 2*(10)*π*(2)

                  v = 40π mm/s

- Since we are considering the coin as a rigid body and not a point mass. We have to determine the velocity of the center of mass of the coin ( Vcm ).

- Consider a coin as a circle. The point of contact of the between the circle ( coin ) is called the center of instantaneous velocity.

- Then mark two horizontal velocity vectors. One starts at the center of mass of the coin ( pointing right ): Denote this as the velocity of center of mass ( Vcm ).

- Other one starts from top most point lying on the circumference of the circle, this vector should be longer than the one made at center of mass (pointing right ): Denote this as the tangential velocity ( v ).

- Now joint the heads of two vectors ( v and Vcm ) with the center of instantaneous velocity ( contact between coin and surface ). Now make a vertical line that starts the top most point passing through center of mass and ends at the center of instantaneous velocity.

- We will end up with two similar triangles. We will use the law of similar triangle and determine the velocity of center of mass ( Vcm ):

                       2r / r = v / Vcm

                       Vcm = v / 2

-  Evaluate the velocity of center of mass ( Vcm ):

                      Vcm = 40π / 2

                      Vcm = 20π  mm/s    

- Use the distance-speed-time relationship and determine how far the coin travelled ( s ) in the computed time in part a:

                      s = Vcm*t

                      s = 20π*0.25

                      s = 5π = 15.70796 mm

Answer: The distance travelled by the coin in the time interval of 0.25 seconds is 15.71 mm ( rounded to nearest tenth )

Answer: [tex]9m=10[/tex] or [tex]m=\frac{10}{9}[/tex]

I don't know your options... but you can check my work below and see if any of the other options fit yours.

Step-by-step explanation:

[tex](x^2 + 3)2 + 7x^2 + 21 =10[/tex]

If [tex]x^2+3=m[/tex], we can rewrite this as;

[tex](m)2+7x^2+21=10\\2m+7x^2+21=10[/tex]

By grouping, we can factor another m.

[tex]2m+(7x^2+21)=10[/tex]

Factor a 7.

[tex]2m+7(x^2+3)=10[/tex]

Rewrite it in terms of m.

[tex]2m+7m=10[/tex]

Combine like terms;

[tex]9m=10[/tex]

Divide by 9

[tex]m=\frac{10}{9}[/tex]

Local minimum at x = 0.

Step-by-step explanation:

Local minimums occur when g'(x) = 0 and g"(x) > 0.

Local maximums occur when g'(x) = 0 and g"(x) < 0.

Set g'(x) equal to 0 and solve:

0 = 2x (x − 1)² (x + 1)²

x = 0, 1, or -1

Evaluate g"(x) at each point:

g"(0) = 2

g"(1) = 0

g"(-1) = 0

There is a local minimum at x = 0.

Answer:

Local minimums occur when g'(x) = 0 and g"(x) > 0.

Local maximums occur when g'(x) = 0 and g"(x) < 0.

Set g'(x) equal to 0 and solve:

0 = 2x (x − 1)² (x + 1)²

x = 0, 1, or -1

Evaluate g"(x) at each point:

g"(0) = 2

g"(1) = 0

g"(-1) = 0

There is a local minimum at x = 0.

Answer:

The cost of a burger is $1.65 and the cost of a gatorade is $1.05.

Step-by-step explanation:

We can solve this question using a system of equations.

I am going to say that:

x is the price of a burger.

y is the price of a gatorade.

6 burgers and 4 gatorades for $14.10

This means that [tex]6x + 4y = 14.10[/tex]

3 burgers and 4 gatorades for $9.15.

This means that [tex]3x + 4y = 9.15[/tex]

Will write 4y as a function of x.

[tex]4y = 9.15 - 3x[/tex]

Replacing in the first equation:

[tex]6x + 4y = 14.10[/tex]

[tex]6x + 9.15 - 3x = 14.10[/tex]

[tex]3x = 4.95[/tex]

[tex]x = \frac{4.95}{3}[/tex]

[tex]x = 1.65[/tex]

And

[tex]4y = 9.15 - 3x[/tex]

[tex]4y = 9.15 - 3*1.65[/tex]

[tex]4y = 4.2[/tex]

[tex]y = \frac{4.2}{4}[/tex]

[tex]y = 1.05[/tex]

The cost of a burger is $1.65 and the cost of a gatorade is $1.05.

Graph A

Step-by-step explanation:

75, 88, 90, 96, 98, 100

The lowest is 75 and the highest is 100 so there should be dots there

The median is between 90 and 96

75, 88, 90,        96, 98, 100

(90+96)/2 =  93  There should be a line at 93 that is the middle of the box

This is either graph A or C

Now find the upper quartile

That is the middle of  96, 98, 100  or 98

Answer:

Let's denote:

x: number of ticket 28$

y: number of ticket 40$

Then, we have:

x + y =5000

28x + 40y = 153200

=> 28(5000 - y) + 40y = 153200

=> 12y = 153200 - 140000

=> 12y =13200

=> y = 1100 (ticket 40$)

=> x = 5000 - 1100 = 3900 (ticket 28$)

Answer:

The sum of the first 70 terms of the sequence [tex]-6, -3,0,3,6, ...[/tex] is 6825.

Step-by-step explanation:

A sequence is a set of numbers that are in order.

In an Arithmetic Sequence the difference between one term and the next is a constant.

[tex]-6, -3,0,3,6, ...[/tex] This sequence has a difference of 3 between each number.

The sum of an arithmetic series is found by multiplying the number of terms times the average of the first and last terms.

                                          [tex]S_n=\frac{n}{2}(2a_1+(n-1)d)[/tex]

where [tex]n[/tex] = the number of terms, [tex]a_1[/tex] = the first term, and [tex]d[/tex] = the common difference.

For our arithmetic sequence, the values of a, d and n are:

So:

[tex]S_{70}=\frac{70}{2}(2(-6)+(70-1)3)\\\\S_{70}=35\left(3\left(70-1\right)-2\cdot \:6\right)=35\left(207-12\right)=35\cdot \:195)=6825[/tex]
