The value of length of segment t in the intersecting chords is determined as 6.93.

The value of length of segment t is calculated by applying intersecting chord theorem, which states that the angle at tangent is half of the arc angle of the two intersecting chords.

Also this theory states that the product of two segments of a chord is equal to the product of the two segments of the second intersecting chord in the circle.

From the diagram, the length of t is calculated by setting up the following equation;

4 x ( 4 + 8)  = t x t

4 (12) = t²

48 = t²

t = √ (48)

t = 6.93

Answer: The cost of each sandwich (S) is $4 and the cost of each bottle of water (B) is $2.

Step-by-step explanation:

10S + 6B = 52 (Equation 1) -- Ramon's purchase

1S + 3B = 10 (Equation 2) -- Wallace's purchase

To solve these equations, we can use a method called substitution. We'll solve Equation 2 for S and substitute it into Equation 1:

From Equation 2, we can isolate S:

1S = 10 - 3B

S = 10 - 3B

Substituting S into Equation 1:

10(10 - 3B) + 6B = 52

100 - 30B + 6B = 52

100 - 24B = 52

-24B = 52 - 100

-24B = -48

B = -48 / -24

B = 2

Now, substitute the value of B back into Equation 2 to find S:

S + 3(2) = 10

S + 6 = 10

S = 10 - 6

S = 4

Answer:

30°

Step-by-step explanation:

angles on a straight line add up to 180°.

angles in a triangle add up to 180°.

XYZ = 180 - 105 = 75°.

angle YZX = 180 - 2x.

so we have YZX + 2x = 180, YZX = 180 - 2x.

angles in triangle add up to 180:

x + YZX + 75 = 180,

x + (180 - 2x) + 75 = 180,

-x + 180 + 75 = 180,

-x = 180 - 180 - 75 = -75,

x = 75°.

YZX = 180 - 2x = 180 2(75) = 180 - 150 = 30

Answer:

84

Step-by-step explanation:

300 times .28 = 84.

Answer: 28% of 300 is 84

Step-by-step explanation:

Write 28% as 28/100.

Since, finding the fraction of a number is the same as multiplying the fraction with the number, we have

28/100 of 300 = 28/100 × 300 OR 0.28 x 300

When you multiply them together, you would get 84. Therefore, the answer to the following would be 84. Hope this helps!

Answer:

See below for an explanation

Step-by-step explanation:

The function [tex]f(x)=\sin(x)[/tex] oscillates between -1 and 1 as it should with equal periods of 2π, but [tex]f(x)=\sin(\sqrt{x})[/tex] has increasingly longer periods of oscillations because of the exponent for x being small (recall that [tex]\sqrt{x}=x^{\frac{1}{2}}[/tex]). If the exponent were to increase, the frequency of these oscillations increase substantially.

I hope this explanation helps!

Check the picture below.

I usually like to see sine and cosine as a distance of a "dark light" over the circle as you see there in the picture, so if the flashlight moves up, the vertical shadow(sine) becomes larger and the horizontal shadow(cosine) becomes smaller, and the same happens on all four Quadrants as the flashlight moves over the arc.

If we look at the value tables there, let's notice, whilst "x" is less than 10 is all honky dory all positive for sine, we hit x = 10 and kaboom it turns negative, thus the drop you see in the sinusoid curve above at x =  10 or close, not exactly but very close.

well, by the time x = 9.5, its root becomes about 3.08 radians and sine of that is still positive, recall, π is about 3.1416 radians, and below π radians, the vertical shadow drops to the III and IV Quadrants, thus negative, so if we square say 3.1416², which is about 9.87, so when "x" is about 9.87, its root will turn to close to 3.1416 radians and sine of that will run to the negative, having the drop you see above, then it goes back up and then back down like any sinusoidal curve as the values of the angle iterate over the Quadrants.

Check the picture below.

Answer:

sin (M) = 1/11 * √34 or (√34) / 11

Step-by-step explanation:

The sine ratio is sin (reference angle) = opposite / hypotenuse.

Plugging in M for the reference angle gives us:

sin (M) = (√34) / 11.  Dividing by 11 is the same as multiplying by 1/11 so alternatively, you could write sin (M) = 1/11 * (√34)

The expression is already in simplest radical form as there are no perfect squares which divide evenly into 34.

554 students is the required number that would have to be sampled

To determine the sample size needed to limit the margin of error in a 95% confidence interval, we can use the formula for the margin of error in a sample mean estimate:

E = z * (σ/√n)

Here, E is the desired margin of error, z is the z-score corresponding to the desired confidence level (for a 95% confidence level, z = 1.96), σ is the standard deviation, and n is the sample size. We can solve for n to find:

n = (z * σ / E)²

Substituting the given values:

n = (1.96 * 300 / 25)²

Now, calculate the value:

n = (23.52)^2 = approximately 553

Answer:

Step-by-step explanation:

You want the center of rotation when figure QRSP is rotated 90° CW to become UVST.

The center of rotation is the point of coincidence of the perpendicular bisectors of the segments between a preimage point and the corresponding image point. It is also the only point on the plane that is invariant with the rotation.

The rectangle names tell us the rotation maps the points as follows:

The fact that point S does not move tells us that it is the center of rotation. As a check, we can see if the perpendicular bisectors of QU, RV and PT intersect at point S. (They do.)

Point S is the center of rotation.

Additional comment

Unfortunately, the image attached to the problem statement distorts the lines and angles. Hence, it cannot be used to find the precise location of the center of rotation. (In fact, the "rectangles" shown are only conceptual rectangles, not actual congruent rectangles.)

The perpendicular bisector of QU seems to pass through S, as it must if S is the center of rotation.

They are 68.27% of emergency calls have a firefighter response time between 7 and 11 minutes.

To determine the percentage of emergency calls with a firefighter response time between 7 and 11 minutes, we need to calculate the area under the normal distribution curve between these two values.

First, let's standardize the values of 7 and 11 using the z-score formula:

z1 = (7 - mean) / standard deviation

= (7 - 9) / 2

= -2 / 2

= -1

z2 = (11 - mean) / standard deviation

= (11 - 9) / 2

= 2 / 2

= 1

Next, we can use a standard normal distribution table or a statistical calculator to find the area under the curve between these z-scores.

The area between z = -1 and z = 1 represents the percentage of emergency calls with a firefighter response time between 7 and 11 minutes.

Using a standard normal distribution table, we get between z = -1 and z = 1 is approximately 0.6827.

The number of more hotdog buns than kaya buns there are in the bakery, obtained from the fractions and ratios of the number of buns are 192 hotdog buns

A ratio is a quantitative representation of the number of times one quantity is contained in another quantity.

The fraction of the buns that are coffee buns = 3/11

The amount of the hotdog buns and kaya buns = The rest of the buns

The ratio of the hotdog buns to the kaya buns = 7 : 5

The total number of hotdog buns and kaya buns = 720 more than the number of coffee buns

The difference between the number of hotdog buns and kaya buns are therefore;

Let x represent the number of buns in the bakery

The number of coffee buns = 3·x/11

The number of hotdog buns and kaya buns = x - 3·x/11 = 8·x/11

8·x/11 = 3·x/11 + 720

Therefore;

8·x/11 - 3·x/11 = 720

5·x/11 = 720

5·x = 11 × 720 = 7920

x = 1584

The number of hotdog buns and kaya buns = 8×1584/11 = 1152

The number of hotdog buns = (7/(7 + 5)) × 1152 = 672

The number of kaya buns = (5/(7 + 5)) × 1152 = 480
