a. The composite function is N(T(t)) = 290t² - 380t + 386.44

b. the number of bacteria after 5.3 hours is 6519 bacteria.

A function is a mathematical equation that shows the relationship between two variables.

A composite function is a function which contains another function.

Since the number of bacteria in a refrtgerated food product is given by N(T) = 29T² - 76T + 30 , 3 < T < 33 where T is the temperature of the food.

Also, when the food is removed from the refrigerator, the temperature is given by T(t) = 5t + 1.4 where t where t is the time in hours.

So, to find the composite function N(T(t)), we substitute T(t) into N(T).

So,

N(T) = 29T² - 76T + 30

N(T(t)) = 29(5t + 1.4)² - 76(5t + 1.4) + 30

Expanding the brackets, we have that

N(T(t)) = 29(10t² + 14 + 1.96) - 76(5t + 1.4) + 30

N(T(t)) = 290t² + 406 + 56.84 - 380t - 106.4 + 30

N(T(t)) = 290t² - 380t + 406 + 56.84 - 106.4 + 30

N(T(t)) = 290t² - 380t + 386.44

So, the function is N(T(t)) = 290t² - 380t + 386.44

Since N(T(t)) = 290t² - 380t + 386.44 is the number of bacteria after t hours.

To find the number of bacteria after 5.3 hours, we substitute t = 5.3 into the equation.

So,

N(T(t)) = 290t² - 380t + 386.44

N(T(5.3)) = 290(5.3)² - 380(5.3) + 386.44

N(T(5.3)) = 290(28.09) - 380(5.3) + 386.44

N(T(5.3)) = 8146.1 - 2014 + 386.44

N(T(5.3)) = 6518.54

N(T(5.3)) ≅ 6519 bacteria

So, the number of bacteria after 5.3 hours is 6519 bacteria.

On solving the provided question, we can say that the slope intercept equation is 12x + 3y = -3 and slope, m = -4

In mathematics, the intersection point is the place on the y-axis where the slope of the line crosses. a place where the y-axis crosses on a line or curve. Y = mx+c, where m stands for the slope and c for the y-intercept, is used as the equation for the straight line to show this. The slope (m) of the line and its y-intercept (b) are emphasised in the equation's intercept form. When an equation has the intercept form (y=mx+b), the slope is m and the y-intercept is b. Some equations can also be rewritten such that they seem to be slope intercepts. If y=x is rewritten as y=1x+0, for instance, the slope and y-intercept are both changed to 1.

the slope intercept equation is

12x + 3y = -3

3y = -12x - 3

y = -4x - 1

also, y = mx + c

The two integers are 1 and 2.

An integer is a number with no decimal or fractional part and it includes negative and positive numbers, including zero.

Integer is a Latin word which means 'whole' or 'intact'. This means integers do not include fractions or decimals.

A number is positive if it is greater than zero, so they are positive integer.

A number is negative if it is less than zero, so they are negative integer.

The sum of reciprocal of the smaller and twice the reciprocal of the larger number

Substitute

[tex]\frac{1}{x} + \frac{2}{y} = 2[/tex]

[tex]\frac{1}{x} + \frac{2}{x + 1} = 2[/tex]

[tex]\frac{x+ 1 + 2x}{x(x +1)} = 2[/tex]

[tex]x + 1 + 2x = 2x^2 + 2x[/tex]

Subtracting 2x on both sides, we get

x + 1 + 2x - 2x = 2x² + 2x - 2x

x + 1 = 2x²

2x² - x - 1 = 0

2x² - 2x + x - 1 = 0

2x(x - 1) + 1(x - 1) = 0

(2x + 1)(x - 1) = 0

x = -1/2 and x = 1

But x = -1/2 is not possible. Becuase x is a positive number.

Answer: D Im doing the quiz

Answer:D:the range is 5, and the IQR is 10.

Step-by-step explanation:

Answer:The range rule of thumb states that the standard deviation (s) is approximately equal to the range (R) divided by 4, where the range is the difference between the maximum and minimum values of a data set.

Using this formula, we can estimate the standard deviation of the heights as:

s = R / 4 = (192.5 - 152.0) / 4 = 20.625 / 4 = 5.156 cm

Comparing this estimate to the actual standard deviation of 12.22 cm, we see that the estimate is off by a factor of approximately 2.37.

Since the estimate is not within 1.7 cm of the actual standard deviation, it suggests that the range rule of thumb is not a very accurate way to estimate the standard deviation of this data set. The standard deviation calculated using the full set of data is much larger than the estimate, which means that the spread of the data is greater than what would be expected based on the range rule of thumb.

The expression "log[a * b.c]" can be rewritten as 2 * log a + log b + log c.

The expression "log[a*b.c]" can be rewritten using the properties of logarithms as follows:

Use the logarithmic property log(a * b) = log a + log b:

log[a * b.c] = log (a * b) + log c

Apply logarithmic property log(a^n) = n * log a:

log[a * b.c] = log (a^2 * b) + log c = 2 * log a + log b + log c

So, the expression "log[a * b.c]" can be rewritten as 2 * log a + log b + log c.

Therefore, the correct answer is as given above. It could then be concluded that the rewritten expression will then be 2 * log a + log b + log c.

The x- and y-components of the vector [tex]\mathbf{\hat a}}[/tex] are 8.9 m/s² and -6.4 m/s², respectively.

In mathematics, components are the parts or elements that make up a larger structure or object. In the context of vectors, components refer to the parts of a vector that describe its direction and magnitude in a particular coordinate system.

To find the x-components and y-components of the vector [tex]\mathbf{\hat a}}[/tex] = (11 m/s², 36 degrees left of -y-axis), we need to determine the direction of the vector. The notation "left of -y-axis" means that the vector makes an angle of 36 degrees with the negative y-axis, as measured counterclockwise from the negative y-axis.

The magnitude (or length) of the vector is given by the first component, which is 11 m/s².

The x-component of the vector can be found by multiplying the magnitude by the cosine of the angle:

x-component = magnitude x cos(angle) = 11 m/s² x cos(36°) = 8.9 m/s²

The y-component of the vector can be found by multiplying the magnitude by the sine of the angle:

y-component = magnitude x sin(angle) = 11 m/s² x sin(36°) = -6.4 m/s²

The negative sign indicates that the y-component is in the opposite direction of the negative y-axis.

Therefore, the x- and y-components of the vector [tex]\mathbf{\hat a}}[/tex] are 8.9 m/s² and -6.4 m/s², respectively.

Expressed as an ordered pair, the components are (8.9 m/s², -6.4 m/s²).

a. If you wanted to find a station with a frequency of 93.3 on your radio dial, you would need to use the formula Frequency = 88 + 0.2 * (Channel Number). Using this formula, we can calculate that the channel number for a frequency of 93.3 is:

Channel Number = (Frequency - 88) / 0.2

Channel Number = (93.3 - 88) / 0.2

Channel Number = 5.3

Therefore, a station with a frequency of 93.3 can be found on channel 5.3 on your radio dial.

b. If you turned the radio dial to be 4 centimeters from the left end of the radio, the channel number would be:

Channel Number = 4 / 0.2

Channel Number = 20

Using the formula Frequency = 88 + 0.2 * (Channel Number), we can calculate that the frequency for channel 20 is:

Frequency = 88 + 0.2 * (Channel Number)

Frequency = 88 + 0.2 * (20)

Frequency = 96.0

Therefore, turning the radio dial to be 4 centimeters from the left end of the radio, you will pick up a station with a frequency of 96.0.

Answer:

Let's call the number of white boards that Mr. Kelso purchased "W", the number of sharpies "S", and the number of glue sticks "G". We know the following information:

W = 5G

S = G + 10

And we also know the total cost of the items:

0.79W + 1.56S + 0.85G = 91.92

We can use the first equation to substitute for W in the second equation:

0.79(5G) + 1.56(G + 10) + 0.85G = 91.92

Expanding and simplifying the equation:

4.95G + 1.56G + 16.6 + 0.85G = 91.92

7.36G + 16.6 = 91.92

7.36G = 75.32

G = 10.25

So Mr. Kelso purchased 10 glue sticks. Using the first equation, we can find that he purchased 5 * 10.25 = 51 white boards. And using the second equation, we can find that he purchased 10.25 + 10 = 20.25 sharpies.

Since the number of each item must be a whole number, we round up or down to the nearest integer. In this case, it would make sense to round up the number of sharpies to 21. So Mr. Kelso purchased 51 white boards, 21 sharpies, and 10 glue sticks.
