Answer:

The illustration is approximately 226 times larder than the actual pollen grain.

Step-by-step explanation:

First of all, we have to write out the size of the actual pollen grain in a manner that is easy for us to work with.

This will be

\((\frac{3}{10}) ^{3}=0.027cm\) wide

The original width of the pollen is 0.027 cm.

Next,

We can take the width of the illustration to be 6.10 cm  wide.

After this,

To get the magnification factor, we will have to use the formula

Magnification = illustrated size/ actual size

This will be the magnification = \(6.10/0.027\) = 255.92 times

Hence, the illustration is approximately 226 times larder than the actual pollen grain.

The prime factorization of 35 include 5 and 7.

A prime number is a natural number greater than one that cannot be calculated as the product of two smaller natural numbers. A composite number is a natural number greater than one that is not prime. 5 is prime, for example, because the only ways to write it as a product, 1 5 or 5 1, involve 5 itself.

The term "Prime Factorization" refers to determining which prime numbers multiply together to produce the original number.

The model should visually represent that Ms. Duda's class hung 100 lanterns before lunch, which is 20% of the total 500 lanterns.

To draw a model showing what percent of 500 lanterns Ms. Duda's class hangs before lunch, we can use a rectangular bar model.

Draw a rectangular bar to represent the total number of lanterns, which is 500. Label it as "Total Lanterns."

Divide the rectangular bar into two parts. One part should represent the number of lanterns hung before lunch, which is 100. Label this section as "Lanterns Before Lunch."

Calculate the percentage of lanterns hung before lunch by dividing the number of lanterns hung before lunch by the total number of lanterns and multiplying by 100. In this case, (100/500) * 100 = 20%.

Draw an arrow pointing to the "Lanterns Before Lunch" section, and write "20%" next to it to represent the percentage.

Answer:

Im not sure but it probably is 5x-4

Enola needs to contribute $4,330.68 per month to the account.

Let's denote the monthly contribution as X.

The interest rate is 0.4% per month.

Since Enola plans to save for 3 years, the total number of months is:

= 3 * 12

= 36 months.

Using formula for compound interest: Future value = Present value * (1 + interest rate)^number of periods

We will plug values:

$5,000 = X * (1 + 0.004)^36

X = $5,000 / (1 + 0.004)^36

X = $5,000 / (1.004)^36

X = $4,330.68248

X = $4,330.68.

The graph of f(x) is the second one, so the correct option is B.

Here we have f(x), a piecewise function, and we want to see which one of the four graphs is the correct one.

You can see that the first domain of the function is:

x ≤ -4

So we must have a closed circle at x = -4, when the parabola ends.

The second domain is:

-4 < x < 1

So x here is not equal to -4 nor 1, so this part starts and ends with open circles.

finally, the linear part starts with a closed circle.

Also, notice that the line has a negative slope, so it goes down, then we can discard the first option.

Then we can see that the correct option is the second graph.

The measure of the angle m∠RQS subtended by the arc RS at the circumference is equal to 70°

The angle subtended by an arc of a circle at it's center is twice the angle it substends anywhere on the circles circumference. Also the arc measure and the angle it subtends at the center of the circle are directly proportional.

arc RS = 2(m∠RQS)

Also arc AD = 140°

2(m∠RQS) = 140°

m∠RQS = 140°/2 {divide through by 2}

m∠RQS = 70°

Part I: The bookkeeper's gross income last year is $9200.61.

Part II: The sum of the bookkeeper's standard deduction and exemption is $9350.

Part III: The bookkeeper’s taxable income last year is -$149.39.

Part I

To find the bookkeeper's gross income, we need to add up the figures in box 1 of both W-2 forms:

Gross income = $2612.98 + $6587.63 = $9200.61

Part II

To find the sum of the bookkeeper's standard deduction and exemption, we simply add them together:

Standard deduction + Exemption = $5700 + $3650 = $9350

Part III

To find the bookkeeper's taxable income, we need to subtract the sum of her exemption and standard deduction from her gross income:

Taxable income = Gross income - (Standard deduction + Exemption)

Taxable income = $9200.61 - $9350

Taxable income = -$149.39

Since the result is negative, the bookkeeper has a tax loss for the year, meaning that she doesn't owe any federal income tax for that year. However, she may be able to carry the loss forward to future tax years to reduce her tax liability in those years.

Answer:

a = 4, b = - 5, c = 5

Step-by-step explanation:

Expand the product of factors on the left side and compare like terms on both sides.

(3x - 1)(ax + b) ← expand using FOIL

= 3ax² + 3bx - ax - b

= 3ax² + (3b - a)x - b

Equating coefficients of like terms with 12x² - 19x + c , then

3a = 12 ( divide both sides by 3 )

a = 4

3b - a = - 19

3b - 4 = - 19 ( add 4 to both sides )

3b = - 15 ( divide both sides by 3 )

b = - 5

c = - b = - ( - 5) = 5

The slope of the line passing through given points is 5/7

We know that the slope is the ratio of the change in y-values to the change in x-values.

We use slope formula,

m = (y2 - y1)/(x2 - x1)

For pair of points (1, 3) and (8, 8),

m1 = (8 - 3)/(8 - 1)

m1 = 5/7

For pair of points (8, 8)  and (15, 13),

m2 = (13 - 8)/(15 - 8)

m2 = 5/7

For pair of points (22,18)  and (29, 23),

m3 = (23 - 18)/(29 - 22)

m3 = 5/7

For pair of points (15, 13)  and (22, 18),

m4 = (18 - 13)/(22 - 15)

m4 = 5/7

Since the rate of change of output values to the input values is constant i.e., 5/7, the slope of the line is 5/7

Therefore, the slope of the line passing through given points is 5/7

Answer: 45°

Step-by-step explanation:

Angles of a triangle always add up to 180°.

So to work out what x is you would have to add 110° and 25° then take it away from 180°

110+25=135°

180-135=45°

Hope this helps :)

It is 45

Step-by-step explanation:

The whole triangle is 180 so adding 110 plus 25 will get you 135. Then subtract 180 from 135 to get 45

The estimated values of f'(2) and f'(8) are -4.5 and -8.5, respectively.

In programming, a function is a self-contained block of code that performs a specific task or set of tasks. It is a reusable piece of code that can be called multiple times from different parts of a program. Functions typically take inputs, called arguments or parameters, and produce outputs, which can be returned to the calling code.

Given by the question.

a.

To determine whether the function has a positive or negative first derivative, we can examine the change in values of f(t) between adjacent values of t. Since the values of f(t) decrease as t increases, the function appears to have a negative first derivative.

To determine the second derivative, we can examine the change in the first derivative. Since the first derivative is negative, it is decreasing as t increases, suggesting a negative second derivative.

Therefore, the function appears to have a negative first derivative and a negative second derivative.

b.

To estimate f'(2) and f'(8) using difference quotients to the right, we can use the following formula:

f'(t) ≈ [f (t + h) - f(t)] / h

where h is a small positive value. To estimate f'(2), we can use h = 2:

f'(2) ≈ [f (4) - f (2)] / 2 = (120 - 129) / 2 = -4.5

To estimate f'(8), we can use h = 2:

f'(8) ≈ [f (10) - f (8)] / 2 = (77 - 94) / 2 = -8.5

\(\frac{7}{3}\) = k  

y = kx

y  = \(\sqr\frac{7}{3} }\)\(\sqrt{36}\)

y = \(\frac{7}{3}\)(6)
