According to the properties of angles in a circle, the measure of angle TSU is 36 degrees.

We can use the properties of angles in a circle to find the measure of angle TSU.

First, we know that angle TSU and angle TU are both subtended by arc TS. Since the length of arc TS is equal to the circumference of the circle, which is 2Πr (where r is the radius of the circle), we can use the length of widehat TU to find the radius of the circle.

widehat TU = 3/2 Π = (3/2) x 180 degrees = 270 degrees

The length of arc TS = 270 degrees

2Πr = 270 degrees

r = (270 degrees) / (2Π)

r = 45

Therefore, the radius of Circle S is 45.

Next, we can use ST = 9 to find the length of arc TS. Since arc TS is subtended by angle TSU, we can use the formula for arc length:

arc length = θr

where θ is the measure of the central angle in radians

The length of arc TS is:

arc TS = (angle TSU) x r

arc TS = (angle TSU) x 45

But arc TS = ST,

9 = (angle TSU) x 45

angle TSU = 9/45

angle TSU = 1/5 radians

angle TSU = (1/5) x (180/Π)

angle TSU = 36 degrees

Therefore, the measure of angle TSU is 36 degrees.

C is a quadratic and D is an exponential function

and...

A is a parabola

E, might trip some people up but communitive property is "at hand", the equation does (a + x) is the same as (x + a) ( <--- for example)

*communitive property is only seen in multiplication and addition

F is where you have to use the distributive property, distribute the 5 to the x and the 0.6

Under the assumption of independence, the expected frequency in the upper left cell is:__________.

A. 12.47

B. 14.56

C. 2.00

D. 11.09

Answer:

Under the assumption of independence, the expected frequency in the upper left cell is 12.47

Option A) 12.47 is the correct Option

Step-by-step explanation:

Given the data in table in the question;

the expected frequency in the upper left cell will be;

Eij = (Ti × Tj) / N

Row total Ti = 38

Column total Tj = 42  

Total frequency N = 128

so we substitute

Eij = (38 × 42) / 128

= 1596 / 128

= 12.468 ≈ 12.47

Therefore Under the assumption of independence, the expected frequency in the upper left cell is 12.47

Option A) 12.47 is the correct Option

The correct graph of the function x² + 4x + 3 is attached

A negative coefficient of "a" is attached to the plotted graph and this made the plotted graph to open downwards

The axis of symmetry x = - b/2a

where b = 4 and a = 1

x = - 4/2(1)

x = -2

The y coordinate is

f(-2) = x² + 4x + 3

f(-2) = (-2)² + 4 *-2 + 3

f(-2) = 4 - 8 + 3

f(-2) = -1

hence the vertex is (-2, -1)

Step-by-step explanation:

Let's start by simplifying the parenthesis. Distribute the 3 to the terms in it.

3x + 2 + 3 + 3x = 23

Simplify the like terms.

6x + 5 = 23

Isolate the x term by subtracting 5 on both sides.

6x = 18

Divide both sides by 6 to get the value of x.

x = 3

Answer:

31/256

Step-by-step explanation:

0.12109375 = 12109375/100000000

= 31/256

Dividing numerator and denominator by 390625.. we have the simplest solution

You can start out by dividing by 5 the numerator and denominator.you would see this division by 5 goes on 8 times

Or you can start out dividing both numerator and denominator by 25, we see this division goes on 4 times

Answer:

Step-by-step explanation:

0.12109375

=\(=\frac{12109375}{100,000,000} \\=\frac{484375}{4,000,000} \\=\frac{19375}{160000} \\=\frac{775}{6400} \\=\frac{31}{256}\)

The values of f(-1), f(0), and f (2) are 0.04, 1 and 625, respectively

The function is given as:

f(x) = 5^2x

For f(-1), we have x = -1

This gives

f(-1) = 5^(2 * -1)

f(-1) = 0.04

For f(0), we have x = 0

This gives

f(0) = 5^(2 * 0)

f(0) = 1

For f(2), we have x = 2

This gives

f(2) = 5^(2 * 2)

f(2) = 625

Hence, the values of f(-1), f(0), and f (2) are 0.04, 1 and 625, respectively

Answer:

Since 2 times a number is multiplication we make it 2x

To determine whether the Law of Sines or the Law of Cosines is needed to solve the triangle, we can compare the given information with the formulas for each law.

The Law of Sines states:

a / sin(A) = b / sin(B) = c / sin(C)

The Law of Cosines states:

c^2 = a^2 + b^2 - 2ab * cos(C)

In this case, we are given the lengths of all three sides of the triangle (a = 6.0, b = 7.7, c = 13.6). Therefore, we have enough information to use the Law of Cosines to solve the triangle.

Using the Law of Cosines, we can find the measures of the angles:

c^2 = a^2 + b^2 - 2ab * cos(C)

(13.6)^2 = (6.0)^2 + (7.7)^2 - 2 * 6.0 * 7.7 * cos(C)

184.96 = 36 + 59.29 - 92.4 * cos(C)

184.96 = 95.29 - 92.4 * cos(C)

92.67 = -92.4 * cos(C)

cos(C) ≈ -1

Since the cosine of an angle cannot be greater than 1 or less than -1, it is not possible for the given triangle to have an angle with a cosine of -1. Therefore, the triangle is not solvable with the given side lengths.

In this case, the Law of Cosines is needed, but the triangle cannot be solved with the given information.
