Answer:

y = 5x- 26

Step-by-step explanation:

x is the independent variable, which means solve for y

y + 6 = 5(x-4)

Distribute

y+6 = 5x -20

Subtract 6 from each side

y+6-6 = 5x -20-6

y = 5x- 26

y = 5x- 26

Answer:

The number of days it take to reach half its height is 99 days

Step-by-step explanation:

The given parameters are;

The height to which the beans stalk grew daily = Twice the initial height

The time duration for the bean stalk to reach maximum height = 100 days

Therefore, the growth of the bean stock is in the form of a geometric progression with a common ratio, r = 2

The formula for a  geometric progression = a×r⁽ⁿ⁻¹⁾

Therefore, the height of the bean is given by the formula a×r⁽ⁿ⁻¹⁾

Where;

The first term = a  = 1 (for analysis)

The number of terms (days) = n = 100 for 100 days

Therefore, we have;

After 100 days, the height of the bean = 1×2⁽¹⁰⁰⁻¹⁾ = 2⁹⁹ = 6.34 × 10²⁹

Half the height = 6.34 × 10²⁹/2 = 3.1291265 × 10²⁹

Which gives;

1×2⁽ⁿ⁻¹⁾ = 3.1291265 × 10²⁹

n - 1 = ㏒(3.1291265 × 10²⁹)/㏒(2) = 98

Which gives;

n - 1 = 98

n = 98 + 1 = 99 days.

Answer:

  x = -9

Step-by-step explanation:

A line with "undefined" slope is a vertical line. Its equation is of the form ...

  x = constant

If the line is to go through a point with an x-coordinate of -9, then that must be the value of the constant.

  x = -9

Answer:

3.11 miles

Step-by-step explanation:

Hello!

First we have to get the distance into meters

The problem says there are 5 kilometers in a race and 1000 meters in a kilometer so 5 kilometers is 5000 meters

Now we turn the meters into miles

It says a mile is about 1609.34 so we can divide the amount of meters by how many meters are in a mile

5000/1609.34 = 3.106

Round to the nearest tenth

3.106 ⇒ 3.11

The answer is 3.11 miles

Answer: 51891840

Step-by-step explanation:

Given : Total bands = 13

Possible number of bands can perform= 8

For arranging in order we use permutations.

By using permutations, the number of  lineups are possible = [tex]^{13}P_8=\dfrac{13!}{(13-8)!}[/tex]

[tex]=\dfrac{13!}{5!}\\\\=\dfrac{13\times12\times11\times10\times9\times8\times7\times6\times5!}{5!}\\\\=51891840[/tex]

Hence, there are total 51891840 line ups are possible.

Answer: (e-5)^2

Step-by-step explanation:

The box method is a good way to solve this, but for a quick explanation, start by finding a single value that when added gets -10 and when multiplied gets +25. We can find that this term is -5. We the can situate -5 into (e-5)^2 equation, where if you FOIL, you will be back at the unfactored equation. Hope this helps

The factored form of e² - 10e + 25 is (e - 5)².

To factor the expression e² - 10e + 25, we can use the method of recognizing it as a perfect square trinomial. A perfect square trinomial is a quadratic expression of the form (a - b)², where 'a' and 'b' are constants.

In the given expression, e² - 10e + 25, the first term (e²) and the last term (25) are perfect squares, and the middle term (-10e) is twice the product of the square roots of the first and last terms.

So, we can rewrite the expression as:

(e - 5)²

Now, if we expand (e - 5)², we get:

(e - 5)(e - 5) = e² - 10e + 25

Therefore, the factored form of e² - 10e + 25 is (e - 5)².

Answer:

Percentage error is 0.0024 %

Step-by-step explanation:

Initial average distance between Earth and moon = 384467 km  

Distance measure by the scientist = 384476 km

Total variation in the distance calculation = 384476 – 384467 = 9 km.

Now we can find the percentage by dividing the variation in distance from the initial measurement and then multiply with hundred.

Percentage error = ( 9 /  384467 ) × 100 = 0.0024 %

Answer:

See below

Step-by-step explanation:

So we have the following six values:

[tex]77.65488139\\\sqrt{0.156}\\368. 5468432...\\253,897,615.\bar3\\14.19274128...\\\\\sqrt{\frac{4}{9} }[/tex]

And we want to determine which are irrational.

Recall what irrational numbers, are they are numbers that do not repeat nor terminate. In other words, they never end, and their digits never repeat.

So, let's go through each one.

77.65488139 is rational. Yes, it has a lot of decimal places but notice there are no ellipses after it. Thus, it terminates and is rational.

√(0.156) is about (use a calculator) 0.39496835... It is not repeating nor does it end. Thus, √(0.156) is irrational.

368.5468432... has the ellipses. Thus, it doesn't repeat and doesn't terminate. It's irrational.

253,897,615.3 has a bar over the 3 at the end. This means that this repeats. Therefore, while it doesn't terminate, it is rational.

14.19274128... has an ellipses. It doesn't repeat nor terminate. It's irrational.

Lastly, the square root can be simplified to 2/3. This is approximately .6666... While this doesn't terminate, it repeats, so it's rational.

Answer: We have 5000 possible combinations.

Step-by-step explanation:

I guess that we want to find the possible combinations for this lock.

We have 4 numbers, so we have 4 selections.

Now, let's count the number of options in each selection.

in the first selection, we have 10 options (0, 1, 2, 3, 4, 5, 6, 7, 8 and 9)

in the second selection, we have 10 options (0, 1, 2, 3, 4, 5, 6, 7, 8 and 9)

in the third selection, we have 10 options (0, 1, 2, 3, 4, 5, 6, 7, 8 and 9)

in the last selection, we have 5 options (0, 2, 4, 6 and 8)

The total number of combinations is equal to the product of the number of options in each selection:

C = 10*10*10*5 = 5000 combinations.

The (interior) angles of a triangle always add up to 180 degrees. To find the exterior angles of a triangle, subtract the interior triangle from 360 degrees.

The total degrees of any polygon is (n-2)×180 (n is the number of angles). 3-2 is 1 and 1 times 180 is 180. Therefore, the angles of a triangle always add up to 180 degrees.

Answer:

the slope of W is less than the slope of Z

Step-by-step explanation:

Function Z

find slope take two points (0,15.8)  (1,15.76)

m=y2-y1/x2-x1

m=(15.76-15.8)/1-0

m=-0.04

the equation for function z : y=-0.04x+15.8

slope of W=-0.0625 which is less than -0.04

y intercept pf W=30, is greater than the y intercept of Z=15.8

Answer: The first statement is true.

Step-by-step explanation: The slope of function Z is -0.04 or - 1/25 The slope of function W is -0.0625 or -1/16.

Tricky! The absolute values of W are larger, but that makes the slope more negative.

Answer:

x can be all real numbers

Step-by-step explanation:

x - 12 ≤ 44 + x

Subtract x from both sides.

-12 ≤ 44

This statement is true, so the inequality is true for all values of x.

Now let's see how this makes sense. Look at the original inequality.

x - 12 ≤ 44 + x

Rewrite as:

x - 12 ≤ x + 44

What does there inequality mean? Subtract 12 from a number, and compare that with adding 44 to the same number. Of course, a number minus 12 is always less than the same number plus 44. It makes sense that this inequality is true for all values of x.

Answer:

Option (F)

Step-by-step explanation:

Cosec of an angle is the ratio of Hypotenuse and Opposite side.

From the figure attached,

ΔABC is a right triangle.

m∠A + m∠B + m∠C = 180°

m∠A + 90 + x = 180

m∠A = 180° - (90 + x)°

        = (90 - x)°

Now csc (90 - x)° = [tex]\frac{\text{Hypotenuse}}{\text{Opposite side}}[/tex]

                            = [tex]\frac{\text{AC}}{\text{BC}}[/tex]

                            = [tex]\frac{5}{3}[/tex]

                            = 1.67

24 eggs / 4 TBSP

Step-by-step explanation

depending on how much quiche you want, you can alter the recipe by doubling, tripling or even quadrupling the batch. For this example, every time 6 eggs were added, 1 tbsp of butter was added, so if we double that, 12 eggs were added and 2 tbsp of butter was added.

Answer:

A conditional statement is something like:

If (a condition is true) Then (something is also true.).

What this says is that ALWAYS that the condition is met, then "something" is also true.

For example:

If A > 3, then A > 2.

This is always true, because if A is larger than 3, then A is always also larger than 2.

Now, if we find a single counter-example, then the "always" is false.

This would mean that the condition is not enough, as we found a case that meets the condition, but the second part of the conditional statement is not true.

For example, if i told you that:

If a number is greater than 234, then the number is also greater than 235.

Now, there are a lot of numbers that are larger than 234 and also are larger than 235.

But here we have a counter-example.

235 is larger than 234, so the initial condition is true, but 235 is not larger than 235.

Then we find a number that makes the statement:

"If a number is greater than 234, then the number is also greater than 235."

false.
