Answer:

 a. 5√3 ft

 b. 8.7 ft

Step-by-step explanation:

The area is the square of the side length, so the side length is the square root of the area:

  s = √A

  s = √(75 ft²) = √(25·3 ft²) = √(3·(5 ft)²)

  s = 5√3 ft ≈ 8.7 ft . . . . . . side length of garden

Answer:

Solution given:

perpendicular [P]=x

base[B]=9

hypotenuse [H]=41

Now.

By using Pythagoras law

H²=P²+B²

41²=x²+9²

x²=41²-9²

x=[tex]\sqrt{1600}=40[/tex]

x=40 is a required answer.

Step-by-step explanation:

I need to be 20 letters long so ya

Answer:

C

Step-by-step explanation:

Any time you move up or down, it affects the "y" coordinate, and going up is positive so 5 units up is [tex]y + 5[/tex].

Moving left or right affects the "x" coordinate and moving left is negative so

[tex]x - 3[/tex]

[tex](x - 3, y + 5)[/tex]

 Hence, C is the correct answer  

9514 1404 393

Answer:

  yes, yes, no; No

Step-by-step explanation:

We have to assume you have no trouble with single-digit addition and comparison of two numbers.

  3+4 > 1   ⇒   7 > 1 . . . . yes

  4+1 > 3   ⇒   5 > 3 . . . . yes

  3+1 > 4   ⇒   4 > 4 . . . . no

These lengths will not make a triangle because the triangle inequality is not satisfied.

Additional comment

You will notice that we found the result of interest when we added the two smallest numbers (1 and 3) and compared the sum to the largest number (4). This is a shortcut you can use for any "will these make a triangle" question. You don't need to bother comparing larger numbers to smaller ones. You already know they are larger.

Answer:

Answer:

When the number of rows or number of columns in the given matrix does not match the number of entries in the vector x.

When the number of columns in A [tex]\neq[/tex] the number of rows in B.

The matrix-vector is not defined.

Step-by-step explanation:

For example:-

Step 1:

Let's assume

[tex]A=\left ( \begin{matrix}-6 & 9\\ 2& 7\\ 1 & 0\end{matrix} \right )[/tex]3x2                 &       [tex]B=\left ( \begin{matrix}1\\ -6\\ 7\end{matrix} \right )[/tex]3x1

Since matrix multiplication of matric A and matrix B is only possible,

When the number of columns in A = Number of rows in B.

Step 2:

Let's A as m x n; Here m = rows and n=columns

B as p x q; Here p = rows and q=columns.

When n [tex]\neq[/tex] p, the matrix-vector is not defined.

That is matrix multiplication Ax is not possible.

Hence the matrix is not defined.

Answer:

Given:

v = 150d

v represents company's production for the coming year

d represents the number of days

150 is the daily production

The rate of change of the function representing the number of vehicles manufactured for the coming year is CONSTANT (150) , and its graph is a STRAIGHT LINE . So, the function is a LINEAR function.

The required value of P would be 64 for the given linear relationship.

A linear relationship is a connection that takes the shape of a straight line on a graph between two distinct variables - x and y. When displaying a linear connection using an equation, the value of y is derived from the value of x, indicating their relationship.

Given that P varies inversely with the square of Q

P = k/Q²

As per the question, if Q is 8 and P is 9,

So 9 = k/8²

⇒ 9 = k/64

Apply cross-multiplication operation,

⇒ k = 576

If Q is 3, then

⇒ P = 576/3²

⇒ P = 576/9

Apply division operation, and we get

⇒ P = 64

Thus, the required value of P would be 64.

Step-by-step explanation:

1. 20 = 10 + 10

2. 20 = 40 - 20

3. 20 = 2 × 10

4. 20 = 40 ÷ 2

5. 20 = 10 + 6 + 4

6. 20 = 5 × 4

Answer: C. Reasonable. The estimate sooms a little higher compared to the actual answer

Step-by-step explanation:

The actual answer to 359+558 is 917. On the other hand, 359 to the nearest ten is 360 while 558 to the nearest ten is 560. The addition of the numbers will be: = 360 + 560 = 920

The estimated answer is 920 while the actual number is 917. Therefore, the estimate is reasonable as the estimate sooms a little higher compared to the actual answer.

Answer:

16,28

Step-by-step explanation:

The requried interval that represents the middle 95% of Shaquana's commute times is (16, 28) minutes

The empirical rule, also known as the three-sigma rule, is a statistical concept that provides a quick estimate of the spread of a normal distribution.

Since Shaquana's commute times are normally distributed with a mean of 22 minutes and a standard deviation of 3 minutes, we can use this information to find the interval that represents the middle 95% of her commute times.

To do this, we need to find the range of values that is two standard deviations away from the mean in either direction.

Lower limit = Mean - 2SD = 22 - 23 = 16 minutes

Upper limit = Mean + 2SD = 22 + 23 = 28 minutes

Therefore, the interval that represents the middle 95% of Shaquana's commute times is (16, 28) minutes. This means that we expect Shaquana's commute time to be between 16 and 28 minutes, with 95% confidence.

Answer:

[tex]\int {7 \sec(\theta) } \, d\theta = 7\ln(\sec(\theta) + \tan(\theta)) + c[/tex]

Step-by-step explanation:

The question is not properly formatted. However, the integral of [tex]\int {7 \sec(\theta) } \, d\theta[/tex] is as follows:

[tex]\int {7 \sec(\theta) } \, d\theta[/tex]

Remove constant 7 out of the integrand

[tex]\int {7 \sec(\theta) } \, d\theta = 7\int {\sec(\theta) } \, d\theta[/tex]

Multiply by 1

[tex]\int {7 \sec(\theta) } \, d\theta = 7\int {\sec(\theta) * 1} \, d\theta[/tex]

Express 1 as: [tex]\frac{\sec(\theta) + \tan(\theta) }{\sec(\theta) + \tan(\theta)}[/tex]

[tex]\int {7 \sec(\theta) } \, d\theta = 7\int {\sec(\theta) * \frac{\sec(\theta) + \tan(\theta) }{\sec(\theta) + \tan(\theta)}} \, d\theta[/tex]

Expand

[tex]\int {7 \sec(\theta) } \, d\theta = 7\int {\frac{\sec^2(\theta) + \sec(\theta)\tan(\theta) }{\sec(\theta) + \tan(\theta)}} \, d\theta[/tex]

Let

[tex]u = \sec(\theta) + \tan(\theta)[/tex]

Differentiate

[tex]\frac{du}{d\theta} = \sec(\theta)\tan(\theta) + sec^2(\theta)[/tex]

Make [tex]d\theta[/tex] the subject

[tex]d\theta = \frac{du}{\sec(\theta)\tan(\theta) + sec^2(\theta)}[/tex]

So, we have:

[tex]\int {7 \sec(\theta) } \, d\theta = 7\int {\frac{\sec^2(\theta) + \sec(\theta)\tan(\theta) }{u}} \,* \frac{du}{\sec(\theta)\tan(\theta) + sec^2(\theta)}[/tex]

Cancel out [tex]\sec(\theta)\tan(\theta) + sec^2(\theta)[/tex]

[tex]\int {7 \sec(\theta) } \, d\theta = 7\int {\frac{1}{u}} \,du}}[/tex]

Integrate

[tex]\int {7 \sec(\theta) } \, d\theta = 7\ln(u) + c[/tex]

Recall that: [tex]u = \sec(\theta) + \tan(\theta)[/tex]

[tex]\int {7 \sec(\theta) } \, d\theta = 7\ln(\sec(\theta) + \tan(\theta)) + c[/tex]
