Answer:  LADB = 29

Step-by-step explanation:

Answer:

see explanation

Step-by-step explanation:

using the identity

sin²x + cos²x = 1

consider left side

(cosA - sinA)²

= (cosA - sinA)(cosA - sinA) ← expand using FOIL

= cos²A - sinAcosA - sinAcosA + sin²A

= cos²A + sin²A - 2sinAcosA

= 1 - 2sinAcosA

= right side

What is circumference?

The circumference of the circle is the length of the curve traced out from the fixed point which is equidistant from the locus of the curve.

Given that:-

The circumference of the circular swimming pool will be:-

C  =  2 π r

C  =  2  x  π  x  7

C   =  44 ft

The steps arranged in the correct order is Add 4 to both sides, Divide both sides of the equation by 3, Take the log of each side, Divide each side by log 2, Add 5 to each side of the equation and Use the Exponential Property and write in decimal form.

An equation is an expression that shows the relationship between two or more numbers and variables.

Given the equation 3(2 ^ (2t - 5)) - 4 = 10

Add 4 to both sides:

3(2 ^ (2t - 5)) - 4 + 4 = 10 + 4

3(2 ^ (2t - 5)) = 14

Divide both sides of the equation by 3:

[3(2 ^ (2t - 5))] / 3 = 14/3

2 ^ (2t - 5) = 14/3

Take the log of each side:

(2t - 5)log(2) = log(14/3)

Divide each side by log 2:

2t - 5 = log(14/3) / log(2)

Add 5 to each side of the equation:

2t = log(14/3) / log(2)

Use the Exponential Property and write in decimal form:

t = 1.11

The steps arranged in the correct order is Add 4 to both sides, Divide both sides of the equation by 3, Take the log of each side, Divide each side by log 2, Add 5 to each side of the equation and Use the Exponential Property and write in decimal form.

Answer:

3

Step-by-step explanation:

Mode is what number occurs the most in data or in this question which number contains the most X's

Answer:

3 is the mode of the data set shown

Step-by-step explanation:

What is shown in the picture is called a data set. What we need to find is the mode. The mode, is the number shown in the data the most. Each x shown represents how many times the number below it shows in the data set. So, all we need to do is find the column with the most x's.

Through doing this, we can see that the column of 3, has the most x's (4 x's). Meaning that 3 is the mode of the data.

Rational

Step-by-step explanation:

Rational numbers are numbers that can be made by dividing two integers, or are the product of two integers. This includes demicals (terminating and repeating), fractions where the numerator and denominator are integers, and perfect squares. This is a terminating decimal, so it is a rational number.

Answer:

b = 10

b = 17

Step-by-step explanation:

Hello!

Usually, when you want two different integer solutions, you probably want the quadratic to be factorable.

So what we want to know is that b should be the sum of the factors in 16.

Factors of 16: 1, 2, 4, 8, 16

Factor pairs:

Factor Sums:

These are our possible b-values.

Check:

Let's try 17 first:

Now 10:

And finally, 8:

Since x = 4 is a repetitive integer, we cannot use 8 as a value for b.

The answers are b = 10, and b = 17.

So for however many weeks you just add another 8 and you keep going but their is no equation for the question you just asked.

Width = [tex]\frac{3}{4}[/tex] units

Perimeter = 11 [tex]\frac{1}{2}[/tex] units

Step-by-step explanation:

   Area can be found with;

A = L * W

   We will plug in the known values and solve.

A = L * W

3 [tex]\frac{3}{4}[/tex] = 5 * W

(3 [tex]\frac{3}{4}[/tex] ) / 5 = (5 * W) / 5

(3 [tex]\frac{3}{4}[/tex] ) / 5 = W

[tex]\frac{3}{4}[/tex]  units = W

   Perimeter can be found with;

P = 2L + 2W

   We will plug in the known values and solve.

P = 2L + 2W

P = 2(5) + 2([tex]\frac{3}{4}[/tex])

P = 10 + 1 [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

total of terriers is 48 with is more than 3 but is lower than 134

Answer: A

Step-by-step explanation:

The area of the square is 10^2 = 100.

The area of the circle is (pi)(5^2) = 25pi.

So, the area of the region in the square but not in the circle is 100 - 25pi.

Thus, the desired probability is (100-25pi)/100, which is about 21.5%

The answer will be A number line going from 27 to 37. An open circle is at 32. Everything to the right of the circle is shaded.

The relation between two expressions that are not equal, employing a sign such as ≠ ‘not equal to’, > ‘greater than’, or < ‘less than’.

We have an expression of inequality:-

(-1/2)p < -16

p > 32 . . . . . . multiply by -2; this reverses the inequality symbol

The open circle will be at 32; the line will be shaded for higher values (to the right).

Hence the answer will be A number line going from 27 to 37. An open circle is at 32. Everything to the right of the circle is shaded.
