what is the standard form of this graph

Answer:

Points A and B are not on the unit circle.

Step-by-step explanation:

Recall that a "unit circle" has a radius of 1, and so if x² + y² ≠ 1, the point is not on a unit circle.

In A we apply the Pythagorean Theorem as follows:  1² + 1² = 2 ≠ 1.

Therefore, point (1, 1) is not a point on the unit circle.

In B:  if we square the x and y components and add these squares together, we get 3/4 + 1/9, which does not equal 1.  Point not on unit circle.

In C, we get 4/9 and 5/9, which eqals 1.  This point C lies on the unit circle.

In D, we get 0.64 + 0.36 = 1, so this point does lie on the unit circle.

Thus:  not on unit circle:  A(1, 1), B(√3/2, 1/3)

On unit circle:  D(0.8, -0.6), C(-2/3, √5/3)

Answer:

b friday

Step-by-step explanation:

I did 228.7t divided by 314.52 which gave me 0.7273

He make his Exchange on Friday.

The correct option is B.

A currency's relative value expressed in terms of another currency is called an exchange rate (or group of currencies). The exchange rate is a significant economic variable for nations with active international trade, like Australia.

In other words, the exchange rate is the cost of one currency relative to another.

We have,

Day                 $                 €

monday          1                0.7102

tuesday           1                0.7053

wednesday     1                0.6869

thursday          1                0.6910

friday               1                0.7273

saturday          1                0.7544

b friday

So, 228.7 / 314. 52

= 0.7273

Thus, he exchanges on Friday.

Answer:

The answer is

→ C.) The graph starts flat but curves steeply upward.

Step-by-step explanation:

Explaining option C:

The quick leaps in y-coordinates indicate that it continues to travel higher up faster and faster while the x-coordinates proceed continuously.

The first choice is incorrect since the slope formula yields a value of 15 for the slope. The second choice is incorrect since it is impossible for it to be a horizontal line unless x = 0, which it is not because it equals 2. The last choice is incorrect because, rather of continuously increasing in size, a parabola function begins to decrease in size (the vertex would be visible in the function if this was a parabola.)

Therefore, Option C.) The graph starts flat but curves steeply upward is your answer.

0.75x + 30 = 0.7x + 14

0.05x + 30 = 14

Only one solution exists for the given equation.

A mathematical statement that demonstrates the equality of two mathematical expressions is a mathematical solution, which is the definition of an equation.

Here,

The mathematical equation given is,

0.75(x + 40) = 0.35(x + 20) + 0.35(x + 20)

By solving it,

0.75(x + 40) = 0.7(x + 20)

0.75x - 0.7x = 14 - 30

0.05x = -16

Therefore, the solution of x,

x = -16/0.05

x = 320

Hence,

Only one solution exists for the given equation.

Given that the diameter of the flower bed is 17 m and the width of the side walk is 2 m for a total out side diameter of 21 m.

Total Area is pi *(D/2)^2 = 346.4 m^2

Now subtract the area of the 17 m diameter flower bed for the area of the sidewalk alone. 346.4 - (pi*(17/2)^2 = 346.4 - 227.0 = 119,4 m^2

Rate of interest for income upto 12012 = 0.5 %

    Interest = 0.5% *12012

                  =0.05 *12012

                  = € 60.06

Rate of interest for income between 12012.01 to 19874 = 2%

    Interest = 2% * 19874

                  = 0.02 * 19874

                   =  € 397.48

Rate of interest for income between 19874.01 to 70044 = 4.5%

 Interest = 0.045 * 55000

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

Explanation:

n = 20 is the sample size

p = 0.035 is the probability of selecting someone who is from multiple births (twins, triplets, etc)

Either someone is a twin/triplet/etc or they aren't. This two option nature is a strong implication we have a binomial probability.

The binomial probability formula is

B(x) = (n C x)*(p)^x*(1-p)^(n-x)

where x is the number of successes and the n C x refers to the nCr combination formula.

We want to know the value of B(3), ie the value of B(x) when we have exactly x = 3 children from multiple births.

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

B(x) = (n C x)*(p)^x*(1-p)^(n-x)

B(3) = (20 C 3)*(0.035)^3*(1-0.035)^(20-3)

B(3) = (1140)*(0.035)^3*(0.965)^(17)

B(3) = 0.026673

There's roughly a 2.6673% chance of the 20 person sample having exactly 3 children who are from multiple births.

Side note: You can compute 20C3 = 1140 using the conventional nCr formula, or you can use Pascal's Triangle as an alternative route.

In this question we must apply geometric properties of angles and triangles to determine that the triangle NET is an isosceles triangle. Isosceles triangles are triangles with two sides of equal length. In addition, we must apply the geometric concept of proportionality.
