Find the exact values of the solutions in the interval 0 <= x < 2pi of the following equations without using a calculator. a) 3sec(x) + 2 = 8

Answer:

24 kilometers

Step-by-step explanation:

Given

Represent the distance with x

[tex]x = 2km\ 400m[/tex]

Required

The distance covered for 5 days (i.e. Monday to Friday)

First, we calculate the distance covered in a day

He covers the same distance when going to school and when coming back from school.

So, the daily distance is:

[tex]Daily = 2 * x[/tex]

[tex]Daily = 2 * (2km\ 400m)[/tex]

[tex]Daily = 4km\ 800m[/tex]

In 5 days, he covers:

[tex]5\ days = 5 * Daily[/tex]

[tex]5\ days = 5 * (4km\ 800m)[/tex]

[tex]5\ days = 5 * (4km+ 800m)[/tex]

Open bracket

[tex]5\ days = 5 * 4km+ 5 * 800m[/tex]

[tex]5\ days = 20km+ 4000m[/tex]

Convert m to km

[tex]5\ days = 20km+ 4km[/tex]

[tex]5\ days = 24km[/tex]

Answer:

Step-by-step explanation:

Let's use "completing the square" to solve this quadratic:  x^2 − 18x + 58 = 0

We want to rewrite the terms "x^2 - 18x" in the form '(x - h)^2 - h^2 and leave the terms '58 = 0' as they are:

Taking half of the coefficient of x (which coefficient is -18), we get -9.  We square this -9, obtaining 81, and then rewrite

"x^2 - 18x"   as  "x^2 - 18x" + 81 - 81."  To this we must append '58 = 0":

x^2 - 18x + 81 - 81 + 58, or x^2 - 18x + 81 - 23 = 0

Now the first three terms condense to the expression

(x - 9)^2, which is then followed by "-23":

(x - 9)^2 = 23

Solve this for x.  Taking the square root of both sides, we get

x - 9 = ± √23

so that one root is x = 9 + √23

and the other is x = 9 - √23

Answer: The plant food produces more blooms on average, but the results aren't as consistent as before.

========================================

Explanation:

The dot plot leads to this data set

{8, 12, 12, 17, 17, 18, 18, 18, 19, 19, 20, 23}

Using pencil/paper, or using technology, you should find the following properties of this data set

The second value is approximate. Both the mean and standard deviation are larger than their original counterparts (mean = 14 and std dev = 2).

Since the mean is larger, this means the data points have been shifted to the right further. The larger standard deviation tells us that the data is more spread out.

So it appears this new plant food has made the number of blooms increase overall, but it's also made the data more inconsistent. A smaller standard deviation would mean a more narrow set of points and therefore more consistent values (they'd all be clumped around the mean better).

Step-by-step explanation:

Answer:

x = 119

z = 28

Step-by-step explanation:

To find x: Because of same-side exterior angles, you can add x and 61 together to find 180 degrees.

x + 61 = 180

Subtraction: x = 119

To find z: Use given quantities, not found variables for most accurate answer. Because of opposite exterior angles, you can equal them to each other.

61 = 5z - 79

Addition: 140 = 5z

Division: 140/5 = 5z/5

Final Answer = 28 = z

Answer:

Yes

Step-by-step explanation:

Because of that it is a proportional relationship.

Answer and Step-by-step explanation:

We are told that there is 24 cupcakes, which total up to be 36 dollars.

c will represent One cupcake.

We would do 36 divided by 24 to find the cost of One cupcake.

[tex]\frac{36}{24} = \frac{3}{2} = 1.5[/tex]

Each cupcake (c) is equal to $1.5.

Equations that would get us to this would be:

36/24 = c

36 = 24c

Answer:

x > -10

Step-by-step explanation:

5x + 13 > -37

subtract 13 from each side:

5x > -50

x > -10

Answer:

X >/ -10 (imagine this is more or equal to symbol lol)

Step-by-step explanation:

1. subtract 13 from both sides

5x +13-13 >/ -37 -13

2. Simplify

5x >/ -50

3. solve for x (which means divide by 5)

5x/5 >/ -50/5

x>/ -10

Answer to the first question: 7/10ths of a mile

Explaination: When adding fractions, you need to have a common denominator. Since dividing 3/10 by 2 to get a denominator of 5 makes 3 a decimal, it's easier to multiply 2/5 by 2 to get a denominator of 10. You do the same to the top that you do to the bottom: [tex]\frac{2*2}{5*2} = \frac{4}{10}[/tex]. From there, just add 4/10 and 3/10 to get the answer: 7/10ths of a mile.

Answer to the second question: Daniel read three (3/10) more books

Explaination: Since you can't evenly multiply 5 or 2 to get the opposite number, it's easier to multiply to the lowest common multiple. The easiest way to find that is to multiply both denominators (5*2=10). You'll have to multiply the numerator by the same amount you multipled the denominator by. For Daniel, that would mean: [tex]\frac{4*2}{5*2} = \frac{8}{10}[/tex]. For Edgar, that would mean: [tex]\frac{1*5}{2*5} = \frac{5}{10}[/tex]. So, Daniel read 3 more books than Edgar.

Answer to the third question: 2/4 mile (or 1/2 a mile)

Explaination: 2/8 can be simplified, by dividing the top and bottom by 2, resulting in 1/4. Since both fractions have the same denominator (/4), you can add them to get 2/4ths. This can be simplified further to half (1/2) a mile.

Answer and Step-by-step explanation:

1. Convert [tex]\frac{2}{5}[/tex] to have a denominator of 10.

[tex]\frac{2}{5}[/tex] × [tex]\frac{2}{2}[/tex] = [tex]\frac{4}{10}[/tex]

[tex]\frac{3}{10} + \frac{4}{10} = \frac{7}{10}[/tex]

Jeremiah ran [tex]\frac{7}{10}[/tex] of a mile in total.

2. Convert the denominators of all the fractions to have a 10.

[tex]\frac{1}{2}[/tex] × [tex]\frac{5}{5} =\frac{5}{10}[/tex]

[tex]\frac{4}{5}[/tex] × [tex]\frac{2}{2} = \frac{8}{10}[/tex]

Daniel read [tex]\frac{3}{10}[/tex] more books than Edgar, since 8 books is more than 5 books by 3 books.

3. Convert [tex]\frac{1}{4}[/tex] to have a denominator of 8.

[tex]\frac{1}{4}[/tex] × [tex]\frac{2}{2} = \frac{2}{8}[/tex]

[tex]\frac{2}{8} +\frac{2}{8}= \frac{4}{8}, or\frac{1}{2}[/tex]

Jared drove [tex]\frac{4}{8}[/tex], or [tex]\frac{1}{2}[/tex] miles in total.

Answer:

96ft

Step-by-step explanation:

First we can find the rectangle which would be

6*12=72

then we can find the triangle, since their are two triangles we can combine them to make a rectnagle so we can just do

6*4=24

then we can add them together

72+24=96

Answer:

B. a = rⁿ

C. a¹/ⁿ = r

Step-by-step explanation:

ⁿ√a = r

The above expression can be simplified as follow:

1. ⁿ√a = r

Recall:

ⁿ√a = a¹/ⁿ

Therefore,

a¹/ⁿ = r

2. ⁿ√a = r

Take the n square of both side

(ⁿ√a)ⁿ = rⁿ

(a¹/ⁿ)ⁿ = rⁿ

a = rⁿ
