Answer:

508.68cm²

Step-by-step explanation:

Volume of a cylinder = πr²h

given r=4.5 cm h =8cm and π=3.14

so volume=

3.14×4.5×4.5×8

=508.68cm²

The following frequency table summarizes last week's bed sales at Cloud Nine Furniture.
Masteriza [31]

Answer:

Option A. 0.20

Step-by-step explanation:

Observations from the given frequency table are :

Total number of beds sold at Cloud Nine Furniture = 3 + 6 + 4 + 2

                                                                                     = 15

Number of twin beds sold = 3

Then, probability that the next bed sold will be a twin bed,

P=\frac{\text{favorable outcome}}{\text{total number of possible outcomes}}

  =\frac{3}{15}

  = 0.20

Therefore, the probability that the next bed sold is a twin bed will be 0.20 or 20%.

Option A. is the correct answer.

The graph of f ′ (x), the derivative of f(x), is continuous for all x and consists of five line segments as shown below. Given f
Nataliya [291]

The maxima of f(x) occur at its critical points, where f '(x) is zero or undefined. We're given f '(x) is continuous, so we only care about the first case. Looking at the plot, we see that f '(x) = 0 when x = -4, x = 0, and x = 5.

Notice that f '(x) ≥ 0 for all x in the interval [0, 5]. This means f(x) is strictly increasing, and so the absolute maximum of f(x) over [0, 5] occurs at x = 5.

By the fundamental theorem of calculus,

\displaystyle f(5) = f(0) + \int_0^5 f'(x) \, dx

The definite integral corresponds to the area of a trapezoid with height 2 and "bases" of length 5 and 2, so

\displaystyle \int_0^5 f'(x) \, dx = \frac{5+2}2 \times 2 = 7

\implies \max\{f(x) \mid 0\le x \le5\} = f(5) = f(0) + 7 = \boxed{13}

Name the property of real numbers illustrated by the equation 16(3t + 4v) = 48t + 64v.
scZoUnD [109]
The property of real numbers illustrated by the equation 16(3t+4v)=48t+ 64v.

 Therefore, the answer is: Distributive property.

 As you can see, you have the equation 16(3t+4v), and when you apply the Distributive property, you obtain:

 16(3t+4v)
 (16)(3t)+(16)(4v)
 48t+64v
