Answer:

To find: After how many months of saving do Sam and Frank have the same amount in their accounts and how much do they have in their accounts at this time

From the graph,

x axis represents number of months,

axis represents Amount saved.

The red graph represents the amount saved by Sam over the number of months

The blue graph represents the amount saved by Frank over the number of months

To find the intersection point of the two graphs.

The intersection point is (4,80)

After 4 months Sam and Frank saved $80.

Hence we get that,

After 4 months, Sam and Frank have the same amount in their accounts. They have $80 in their accounts.

Answer is: After 4 months, Sam and Frank have the same amount in their accounts. They have $80 in their accounts.

    Equivalent fractions are those that, despite their visual differences, reflect the same value. For instance, if you take a cake and cut it into two equal pieces, you will have consumed half of the cake.

          When two fractions are expressed in their simplest form, they are said to be equivalent. When broken down into its simplest components, the fraction 26/28 equals 13/14. You only need to multiply the numerator and denominator of the reduced fraction (13/14) by the same natural number, i.e., multiply by 2, 3, 4, 5, 6 to get analogous fractions.

    In decimal form, 13/14 is 0.92857142857143.

x represents the number of packages of coffee sold

y represents the number of packages of pastry sold

We were the cost of a package of coffee is $6 and the cost of a package of pastry is $4. If the total amount made from selling x packages of coffee and y packages of pastry is $72, then the equation representing this scenario is

6x + 4y = 72

Also, we were told that she sold 2 more packages of coffee than pastries. This means that

x = y + 2

Thus, the system of linear equations is

6x + 4y = 72

x = y + 2

We would plot these equations on the graph. The graph is shown below

The red line represents x = y + 2

The bu line represents x = y + 2

To find the slope of a line that passes through two points, we can use the following formula:

Then, we have:

Line EF

Line GH

Now, when graphing the two lines, we have:

If two lines have equal slopes, then the lines are parallel. As we can see, their slopes are equal, therefore the lines EF and GH are parallel.

Line JK

Line LM

Now, when graphing the two lines, we have:

As we can see, the slopes of these lines are different, so they are not parallel. Let us see if their respective slopes have the relationship shown below:

Since their respective slopes do not have the relationship shown below, then the lines are not perpendicular.

Line NP

Line QR

Now, when graphing the two lines, we have:

Two lines are perpendicular if their slopes have the following relationship:

In this case, we have:

Since the slopes of the lines NP and QR satisfy the previous relationship, then this pair of lines are perpendicular.

Line ST

The line ST has an indefinite slope because it is not possible to divide by zero. Lines that have an indefinite slope are vertical.

Line VW

Line VW has a slope of 0. Lines that have a slope of 0 are horizontal.

Now, when graphing the two lines, we have:

As we can see in the graph, the ST and VW lines are perpendicular.

Answer:

tan t = 7/24

csc t = 25/7

sec t = 25/24

cot t = 24/7

Explanation:

From the question, we're told that sin t = 7/25 and cos t = 24/25. Since we know the identities of sine and cosine to be as follows we can go ahead and determine tan t as shown below;

Let's go ahead and find cosecant t (csc t);

For sec t, we'll have;

For cot t;

Vertical asymptotes are when the denominator is 0 but the numerator isn't 0.

[tex]x-36=0 \implies x=36[/tex]

Since this value of x does not make the numerator equal to 0, the vertical asymptote is [tex]x=36[/tex].

Horizontal asymptotes are the limits as [tex]x \to \pm \infty[/tex].

[tex]\lim_{x \to \infty} \frac{6x}{x-36}=\lim_{x \to \infty}=\frac{6}{1-\frac{36}{x}}=6\\\\\lim_{x \to -\infty} \frac{6x}{x-36}=\lim_{x \to -\infty}=\frac{6}{1-\frac{36}{x}}=6\\\\[/tex]

Answer: f(h) = (2 pi (5x + 2)^2)

Step-by-step explanation:

1) Set the area of the circle in an equation

f(h) = pi r ^2

2) Set r to the rate that the circle is growing

The rate is 5x +2 because its starting value is two, and the 5x because it is growing 5 inches per hour.

f(h) = (2 pi (5x + 2)^2)

[tex]k=4[/tex].

Answer:

k = 4

Step-by-step explanation:

a) Simplify both sides of the equation.

20 + 7k = 8(k + 2)

20 + 7k = (8)(k) + (8)(2)

20 + 7k = 8k + 16

7k + 20 = 8k + 16

b) Subtract 8k from both sides.

7k + 20 − 8k = 8k + 16 − 8k

−k + 20 = 16

c) Subtract 20 from both sides.

−k + 20 − 20 = 16 − 20

−k = −4

Divide both sides by -1.

-k/-1 = -4/-1

k = 4

A package of 3 pairs of insulated socks costs $15.87, thus the unit price of the pair of socks can be calculated as $5.29 via the unitary method.

A unit price is the cost of a single object or unit of measurement, such as a pound, a kilogram, or a pint, and it is used to compare the prices of similar products offered in various weights and quantities.

Selling more than one unit of the same product at a discount from its unit price is known as multiple pricing.

A price stated in terms of a certain amount per predetermined or standard unit of good or service agreed to purchase the gravel for 50 cents per yard.

Frequently a price that is quoted that includes both the base unit of the good or service and any additional costs (such as shipment or installation).

Using the average rate of change, it is found that:

A. The average population decline between 1984 and 2018 was of 2.25 thousand deer a year.

B. The population would have reached 225 thousand deer between 2017 and 2018.

C.

The rates are as follows:

Meaning that between 1994 and 2004 there was a increase in the population of deer, and from 2004 to 2014 there was a decrease.

The average rate of change of a function is given by the change in the output divided by the change in the input. Hence, over an interval [a,b], the rate is given as follows:

[tex]r = \frac{f(b) - f(a)}{b - a}[/tex]

For 1984 and 2018, we have that:

Hence the rate is:

r = (173.50 - 250)/(2018 - 1984) = -2.25 thousand deer a year.

For item b, the situation is modeled by a linear function, as follows:

D(t) = 230.50 - 1.45t.

The population would be of 225 thousand deer when D(t) = 225, hence:

230.50 - 1.45t = 225

1.45t = 5.5

t = 5.5/1.45

t = 3.79.

Hence between the years of 2017 and 2018.
