Classify the triangle by its sides.

Answer:

9/10

Step-by-step explanation:

8.6-4x2+3/10- multiply first 4x2=8

8.6-8+3/10 - subtract 8.6-8+.6

.6+3/10= 9/10

Problem 1

A sequence is just a list of numbers where the order matters. Something like (1,2,3,4,5) is different from (3,1,2,5,4)

A series is where you add up that list of numbers to get a single value. For instance, the sum of the list (1,2,3) is 1+2+3 = 6. This is basically a partial sum when talking about infinite sequences because the next partial sum would be 1+2+3+4 = 10 and the next partial sum would be 1+2+3+4+5 = 15, and so on.

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

Problem 2

Why is this? Each time we get a partial sum, we're basically forming a new sequence. We're forming a sequence of sums. Going back to the example in problem 1, we had the partial sums (6,10,15). If we keep this process going, we'll have the list of partial sums grow forever and not approach some finite value. Therefore, this series diverges.

If the sums were to slowly get closer to some fixed value, then we would say the series converges.

Answer:

P = 28.66 ft

Step-by-step explanation:

So perimeter of half circle

= 2π × 6/2

= 2π × 4/2

= 8π ft/2

= 4 π

Total Perimeter = 6 ft + 8π/2 ft + 10 ft +

= 6 ft + 4 π ft + 10 ft

= 28.666 ft

Total Perimeter = 28.66 ft

Answer:

28.56

Step-by-step explanation:

The sides of the triangles are already given, so that will be 16. The diameter of the circle is given to be 8, so the radius will be half of it, 4. The circumference of a circle 2πr, so the circumference is 8π. we need to divide this by two because it is a semicircle, so the circumference of the semicircle is 4π. The answer should be 16+4π, and we can substitute in 3.14 for π to get 12.56+16=28.56

Answer:

C. 72

Step-by-step explanation:

The whole angle measures 106 degrees as mentioned on top and we know that angle HFG is 34 degrees because it says so in that angle. Just do this: 106-34. The answer is 72. We subtract because we're finding the remaining/missing number in this problem. If you want to check if your answer is correct, you can add 72 and 34.

Another way you could do this is by just adding each option with 34 to see if you get a total of 106.

Answer:

Based on the data provided and using logical reasoning, Mr Smith has seven children, four sons and three daughters.

Logical reasoning means using critical thinking skills to provide solutions to given problems.

The number of children Mr. Smith has can be determined by using the skill of logical reasoning.

Assuming that son has two brothers, then he also has two sisters.

Each sister has one sister and three brothers.

This scenario does not satisfy the conditions.

Assuming that son has three brothers, then he also has three sisters.

Each sister has two sisters and four brothers.

Therefore, Mr Smith has seven children, four sons and three daughters.

Step-by-step explanation:

his salary =$2000

his commission should be (to make a total of $4000/month )=$4000-$2000 =$2000

let he should sell x amount over $7000 to get $2000 commission

So,   7% of x = 2000

             7x/100 = 2000

               x= (2000*100)/7 =28571.43 approx

As he will get commission on sales over $ 7000,so his should sell in a month

                             =$7000+$28571.43

                             = $ 35571.43

Answer:

the measure of angle is m(<a)=40

Step-by-step explanation:

the intirior angles of all triangles add up to 180

with this you can subtract the 90 degree angle and the 50 degree angle from the total of 180 degrees.

180

90

-50

---------

=40 degreese

hoped this helped.

Step-by-step explanation:

a+50+90=180°(being sum of angle of right angled▲)

or, a+140= 180°

or, a=180°_ 140°

Therefore, a=40°

Answer:

y = 5

x = 0

Step-by-step explanation:

soo i think elimination was this:

    so first lets make -x = 3x

so we multiply -3 to the whole equation

3x + 3y = 15

now we eliminate (i think this is elimination)

    3x + 5y = 25

   -

    3x + 3y = 15

----------------------------

     0 + 2y = 10

2y = 10

y = 5

now substitute to one of the original equations

3x + 5(5) = 25

3x + 25 = 25

3x = 0

x = 0

now lets check

-0 -5 = -5?

-5 = -5

Answer:

2k + 8 = 0

2k + 8 - 8 = 0 - 8

2k = - 8

2k/2 = - 8/2

k = - 4

Step-by-step explanation:

you gotta put the 8 on the other side by subtracting and the divide both sides to get k

Answer:

k = -4

Step-by-step explanation:

2k + 8 = 0

Subtract 8 from both sides.

2k = -8

Divide both sides by 2.

k = -4

Answer:

[tex]1. \frac{4}{3}[/tex]

[tex]2.\frac{1}{3}[/tex]

Step-by-step explanation:

To find the scale factors, you find the length of one side from the image, and divide it by the length of the similar side in the image.

So, for #1, the image side is 8 units, and the pre-image is 6.

8/6 = 4/3

For #2, the image is  3 units, and the pre-image is 9 units.

3/9 = 1/3

Answer:

y = sec(x) has a range of f(x) ≤ -1 and f(x) ≥ 1

Thus does not include zero in the range scale.

Extra's:

y = cos(x) has a range of -1 ≤ f(x) ≤ 1

y = cot(x) has infinity range

y = tan(x) has infinity range.

Answer:

sec x

Step-by-step explanation:

Let's set each function equal to zero to see if they have zero in their function.

If there is no solution, then we no solution of zero.

[tex] \cos(x) = 0[/tex]

[tex]x = \frac{\pi}{2} + 2\pi(n)[/tex]

So there is a solution of zero.

[tex] \cot(x) = 0[/tex]

[tex] \frac{ \cos(x) }{ \sin(x) } = 0[/tex]

There answer here is

[tex]x = \frac{\pi}{2} + 2\pi(n)[/tex]

So there is a solution. of zero here

If cot x=0, has a solution of zero, then tan x does as well. Since we can use

[tex] \frac{ \sin(x) }{ \cos(x) } = \tan(x) [/tex]

[tex] \frac{ \sin(x) }{ \cos(x) } = 0[/tex]

The answer here will be

[tex]0 + 2\pi(n)[/tex]

So that leaves sec x.

Proof:

[tex] \sec(x) = \frac{1}{ \cos(x) } [/tex]

1 divided by any number won't equal zero, so the solution will never be 0.
