Write the equation of a line that is parallel y = 4x - 7 and goes through the point (4,1).

The given equation r² - 15 = t + 19 is the equation of a parabola with vertex at (h, k) = (0, -34) and focal length |p| = 1/4.

I assume that the question is to describe or graph the equation r² - 15 = t + 19.

The given equation r² - 15 = t + 19 is the equation of a parabola with vertex at (h, k) = (0, -34) and focal length |p| = 1/4.

4p(y - k) = (x - h)² is the common equation for a parabola that faces up and down and has a vertex at (h, k) and a focal length of |p|.

Let us re-write the given equation in the standard form.

r² - 15 = t + 19

⇒ r² = t + 19 + 15

⇒ r² = t + 34

⇒ (r - 0)² = t + 34 (r can be written as r - 0)

⇒ (r - 0)² = t - (-34) (+34 is written as -(-34))

⇒ (r - 0)² = 4 × 1/4 × (t - (-34))

(4 × 1/4 is equal to 1. The given equation is unaffected by a multiplication by 1.)

⇒ 4 × 1/4 × (t - (-34)) = (r - 0)²  this equation is in the standard form. And here we have |p| = 1/4 and (h, k) = (0, -34).

4(4+7) is the equivalent expression uses GCF and Distributive Property to find the sum of to 16+28.

The greatest positive integer m that divides both x and y is the GCF of two or more non-zero integers, x and y. As a result, the greatest common factor is also referred to as the Highest Common Divisor (HCD), the Highest Common Factor (HCF), or the Greatest Common Divisor (GCD).

According to the distributive property, an expression in the form A (B + C) can be solved as A (B + C) = AB + AC. This distributive law also applies to subtraction and is denoted by A (B - C) = AB - AC. This means that the other two operands share operand A.

The given expression is 16 + 28.

The greatest common factor is 4.

So taking the greatest common factor from the both the numbers.

We get, 4 (4+7)

The population of Tacoma in 2017 would be 865,527.

If the population grows by 9% every year, the population would grow at a compound rate each year and the equation that can be used to determine the population in 2017 would be an exponential equation.

Compound growth is when both the existing population and the increase in population every year.

The equation that can be used to determine the population of Tacoma in 2017 is:

The formula for calculating future value:

FV = P (1 + r)^n

Where:

200,000 x (1 + 0.09)^17

200,000 x (1.09^17) = 865,526.68

In order to round  865,526.68 to the nearest whole number , look at the tenth figure, if it is greater or equal to 5, add one to the units digit and change the tenth and hundredth digit to 0. So,  865,526.68 becomes  865,527.

The unitary method is a technique used to find the solution by first finding the value of a single unit and then multiplying the value to get the required answer.

Here, we are given that Mr. Farley used 4 pounds of hamburger to

make 10 hamburger patties.

Given that all of these patties are of the same size, an equal amount of hamburger will be used to make each patty.

We have,

For 10 patties, we need ⇒ 4 pounds of hamburger.

Answer:

the answer is D

Step-by-step explanation:

because it has two straight lines

We know that the irrational number is between:

6 < √45 < 7

And a good estimation is √45 = 6.71

Here we just need to find a lower and upper bound for the given irrational number.

To do it, we just need to find a square number larger and a square number smaller than the number inside the square root.

The larger one will be:

7*7 = 49

The smaller one will be:

6*6 = 36

Then we can write:

√36 < √45 < √49

6 < √45 < 7

So we now know that our number is between 6 and 7, that is already a good estimation, now you can also try to see if it is closer to 6 or 7, by taking the direct square root you will get:

Now just take the product between numbers of the form:

6.10*6.10 = 37.21

And so on, until we almost reach 45.

We will get:

6.71*6.71 = 45.02

So a good estimation is √45 = 6.71

Second part;

r = 4

[tex]a_{6} = 9216 [/tex]

Practice:

r = 8

[tex]a_{7} = 0.3125 [/tex]

Third part;

Please see the detailed reasons in following section

Fourth part;

[tex] {a}_{n} = 4 × {a}_{n-1}[/tex]

[tex] {a}_{n} = 0.2 × {a}_{n-1}[/tex]

First part;

The formula for geometric progression can be presented as follows;

[tex] a_{n} = a_{1} \times {r}^{n - 1} [/tex]

[tex]a_{4} =108 = a_{1} \times {r}^{4 - 1} [/tex]

Where;

[tex]a_{1} = 4 \: and \: a_{4} = 108[/tex]

We have;

[tex]a_{4} =108 = 4 \times {r}^{4 - 1} = 4 \cdot {r}^{3} [/tex]

Which gives;

[tex] {r}^{3} = \frac{108}{4} = 27[/tex]

[tex]r = \sqrt[3]{27} = 3[/tex]

r = 3

Therefore;

[tex]a_{8} = 4 \times {3}^{7} = 8748 [/tex]

Second part;

Where;

[tex]a_{1} = 9 \: and \: a_{3} = 144[/tex]

Therefore;

[tex] {r}^{2} = \frac{144}{9} = 16[/tex]

[tex]r = \sqrt{16} = 4[/tex]

r = 4

Which gives;

[tex]a_{6} = 9 \times {4}^{5} = 9216 [/tex]

Practice;

[tex]a_{1} = 3 \: and \: a_{4} = 1536[/tex]

Therefore;

[tex] {r}^{3} = \frac{1536}{3} = 512[/tex]

[tex]r = \sqrt[3]{512} = 8[/tex]

r = 8

[tex]a_{1} = 20 \: and \: a_{3} = 5[/tex]

Therefore;

[tex] {r}^{2} = \frac{5}{20} = 0.25[/tex]

[tex]r = \sqrt{0.25} = 0.5[/tex]

Which gives;

[tex]a_{7} = 20 \times {0.5}^{6} = 0.3125 [/tex]

Third part

Recursively means expression in terms of previous terms

The meaning of the equation is that each term of a geometric sequence is given by the product of the common ratio and the previous term

Fourth part;

The recursive formula for the sequence, {2, 8, 32, 128...} is found as follows;

r = 8/2 = 4

Therefore;

[tex] {a}_{n} = 4 × {a}_{n-1}[/tex]

Part;

The sequence is {200, 40, 8, 1.6...}

The common ratio is; 40/200 = 0.2

Step-by-step explanation:

Because poor number from 0 to 4

The compound inequality is: x<20 and x>10

Given,  a quantity of x is greater than 10 and less than 20.

A compound inequality (also known as a compounded inequality) is created when two or more inequalities are coupled with and. One part of an inequality must be true for a value to be a solution to an or inequality. It must make both parts true in order to be the solution to an inequality. X<3 or X>2, for instance.

Divide a compound inequality into two independent ones before attempting to solve it. Choose either a union of sets ("or") and an intersection of sets as the appropriate response ("and"). Then, resolve the graph and all inequalities.

Simply put, a compound inequality is more than one inequality that we want to address simultaneously. When referring to the resolution of both inequalities, we can either use the term "and" or "or."

There will be 5 cases and 10 additional units.

Here, we are given that 60 units are needed with 14 units per case.

The total number of units required = 60

Units required for 1 case = 14

Let the total number of cases = n

Thus, total number of units required for n cases = 14n

⇒ 60 = 14n

14n = 60

n = 60/ 14

n = 4.285

Thus, we get that the number of cases = 4.285

But, since cases cannot be in decimals, we need to round off n to 5 ( as 4 cases won't add up to 60).

Thus, the total number of cases are 5.

Additional units = 14 × 5 - 60
