-3(5+k)≥-23-k solve for k

The given expression can be solved by determining the product of irrational numbers.  

Irrational number is a real number that cannot be expressed as the quotient of two integers. If a square root of a number is not a perfect square root, then it is an irrational number.  

In the given expression, there are two rational numbers 7 and 3 while two irrational numbers √7 and √7.

The integer 7 and 3 can be multiplied. Hence,

7√7*3√7=7*3*√7*√7=21*√7*√7

When multiplying terms in square root, √a*√b=√ab. Hence,

21*√7*√7=21√7*7

As square root of a number is the number multiplying itself i.e., √a*a=a

21√7*7= 21*7=147

The product of the expression 7√7.3√7 is 147

Answer:

Distributive property is the answer

The angle of ∠FEG is 58 degrees

The angle DEF is a right angle.

Therefore,

∠DEF = 90°

Hence,

∠FEG + ∠GED = ∠DEF

∠FEG  = 5x - 22

∠GED = 2x

∠DEF = 5x - 22 + 2x

90 = 5x + 2x - 22

90  = 7x - 22

90 + 22 = 7x

112 = 7x

divide both sides by 7

x = 112 / 7

x = 16

∠FEG  = 5x - 22

∠FEG  = 5(16) - 22

∠FEG  = 80 - 22

∠FEG  = 58°

The surface area of the triangular prism is 136 cm square.

The surface area of a triangular prism can be found as follows;

Therefore,

surface area of a triangular prism = (perimeter of the triangle × height of prism) + (2 × base area)

Hence,

perimeter of the triangle = 5 + 5 + 6

perimeter of the triangle = 16 cm

height of prism = 7 cm

base area = 1 / 2 bh

base area =  1 / 2 × 4 × 6

base area = 24 / 2

base area = 12 cm²

Therefore,

surface area of a triangular prism = (16 × 7) + (2 × 12)

The inverse of an exponential function, the natural log is the logarithm to the base of the number e. Natural logarithms are unique varieties of logarithms that are employed in the treatment of time and growth-related issues.

The distinction between log and ln is that log is expressed in terms of base 10, while ln is expressed in terms of base e. As an illustration, log of base 2 is denoted by log2 and log of base e by loge = ln (natural log).

Answer: 57.79

No Extraneous solution

The given equation is

  ( 7x + 6 ) ^ 1/2 - (9 + 4x ) ^ 1/2 = 0

We have to find the value of x

[tex]\sqrt{7x + 6}[/tex] = [tex]\sqrt{9 + 4x}[/tex]

Squaring both sides of the equation

[tex](\sqrt{ 7x + 6} )^{2}[/tex] = [tex](\sqrt{9 + 4x})^{2}[/tex]

7x + 6 = 9 +4x

3x = 3

x = 1

To know whether the value of x is the extraneous solution or not, put the value of x in the equation

[tex]\sqrt{7 * 1 + 6}[/tex] -[tex]\sqrt{ 9 + 4 * 1}[/tex] = 0

[tex]\sqrt{13}[/tex] - [tex]\sqrt{13}[/tex] =0

0 = 0

Therefore there is no extraneous solution to the equation as x = 0 is the solution of the equation.

Answer: 2979 Zeroes

Step-by-step explanation:

1. Figure out what 10^2985 is. (It's one followed by 2985 zeroes).

2. Using that knowledge, make 7.185629 a whole number. To do that, you need to multiply it by a number that has the same number of zeroes as it does to move the decimal place one by one to the right. In this case, it is 1,000,000, because it has 6 zeroes and you need to move the decimal point past 6 numbers (after 7 in 7.185629).

3. Subtract 2985 by 6, because you used 6 zeroes.

4. This gives you the answer 2979 zeroes because 2985 zeroes - 6 zeroes= 2979 zeroes.

p(rolling an 8) with one regular die if we roll the die just once is 0.

A regular die has 6 sides. One each side, a unique number is written from 1 to 6. Thus, when a regular die is rolled, the outcomes can be-

1, 2, 3, 4, 5, 6

Thus, the sample space = { 1, 2, 3, 4, 5, 6 }

The probability of getting any one of the numbers will be 1/6 as total number of outcomes are 6.

Now, we need the probability of rolling a 8.

As we can see 8 is not a value in the sample space.

Thus, P(rolling an 8) will be ⇒ 0/6 = 0. That is, 8 will never be rolled.

Identify slope from a graph

The mathematical definition of slope is very similar to our everyday one. In math, slope is used to describe the steepness and direction of lines. By just looking at the graph of a line, you can learn some things about its slope, especially relative to other lines graphed on the same coordinate plane. Consider the graphs of the three lines shown below:

You can determine the slope of a line from its graph by looking at the rise and run. One characteristic of a line is that its slope is constant all the way along it. So, you can choose any 2 points along the graph of the line to figure out the slope. Let’s look at an example.

EXAMPLE

Use the graph to find the slope of the line.

A line that crosses the points (2,1) and (6,3). A blue line labeled Rise goes up two units from the point (2,1). A red line labeled Run goes left from the point (6,3) so that it forms a triangle with the main line and the Rise line. A formula says slope equals rise over run.

EXAMPLE

Use the graph to find the slope of the two lines.

A graph showing two lines with their rise and run. The first line is drawn through the points (-2,1) and (-1,5). The rise goes up from the point (-2,1) to join with the run line that goes right to the point (-1,5). The second line is drawn through the points (-1,-2) and (3,-1). The rise goes up from the point (-1,-2) to join with the run to go right to the point (3,-1).

Salma bought 32 ounces of strawberries and the price in dollars per ounce of each strawberries is 0.45

In this question, Salma bought two pounds of strawberries for $14.40

We need to find the price, in dollars per ounce of strawberries

We know that 1 pound = 16 ounces

2 pounds of strawberries = 2 × 16 ounces of strawberries

                                          = 32 ounces of strawberries

By unitary method, the required price is,

14.40 ÷ 32 = 0.45 dollars per ounce
