Answer:

1372 cubic ft.

Step-by-step explanation:

V=\frac{4}{3} \pi 7^3

V=\frac{4}{3} \pi 343

V=457\frac{1}{3} \pi

Since pi is 3 to find the approximate answer, do:
V=457\frac{1}{3} (3)

V=1372

Hence, the volume of the sphere is approximately 1372 cubic ft.

Answer:

V = 1,372 ft³

Step-by-step explanation:

You have been given the equation necessary for calculating the volume of a sphere:

V = \frac{4}{3} \pi r^{3}

In this formula, "V" represents the volume, "π" is the given value (3), and "r" is the radius. While you have not been given the radius, you have been given the diameter (14 ft). The radius is half of the diameter.

radius = diameter / 2

radius = 14 ft / 2

radius = 7 ft

Now, you can plug this value into the formula and simplify to find the volume.

 V = \frac{4}{3}\pi r^{3}                                         <----- Volume formula

V = \frac{4}{3} * (3) *r^{3}                               <----- Plug 3 in for "π"

V = \frac{4}{3} * (3) * 7^{3}                                <----- Plug 7 in for "r"

V = \frac{4}{3} * (3) * (343)                           <----- Solve 7³

V = 1,372  ft^{3}                                   <----- Multiply all the terms together

9. The figure shows a rectangle with its length and
lora16 [44]

Answer:

875cm^2

Step-by-step explanation:

since opposite sides are equal

3x-y=2x+y

x=2y                                                      

y=x/2                                                                      ....(i)

thus new length=2x+y

=2x+(x/2)                                                              [using (i)]

=(4x+x)/2

l=5x/2                                                                   .....(ii)

now,

perimeter=2(l+b)=120cm

l+b=60cm            

from figure and using (ii)

[5x/2]+2x-3=60

[5x+4x-6]/2=60

9x-6=120

9x=126

x=126/9

x=14                                                                 ..........(iii)

substitute (iii) in (i)

y=14/2

y=7                                                                  ...........(iv)

From figure,

length=2x+y                                                   [using (iii) and (iv)]

=2x14+7

length=35cm

breadth=2x-3

=2x14-3                                                          ....[using(iii)]

=28-3

breadth=25cm

now,

Area=lxb

=35x25

=875cm^2

Find the minimum value if f(x) = xe^x over [-2,0]
SashulF [63]

Given function:

f(x)=xe^x

The minimum value of the function can be found by setting the first derivative of the function to zero.

f^{\prime}(x)=xe^x+e^x\begin{gathered} xe^x+e^x\text{ = 0} \\ e^x(x\text{ + 1)  = 0} \end{gathered}

Solving for x:

\begin{gathered} x\text{ + 1 = 0} \\ x\text{ = -1} \end{gathered}\begin{gathered} e^x\text{ = 0} \\ \text{Does not exist} \end{gathered}

Substituting the value of x into the original function:

\begin{gathered} f(x=1)=-1\times e^{^{-1}}_{} \\ =\text{ -}0.368 \end{gathered}

Hence, the minimum value in the given range is (-1, -0.368)

For a quadratic function ƒ(x)=ax2+bx+c, ƒ(−1)&lt;1, ƒ(1)&gt;−1, and ƒ(3)&lt;−4. What could be the sign of a?
denis23 [38]

Answer:

"a" must be negative

Step-by-step explanation:

The slope between points (-1, 1) and (1, -1) is a minimum of (-1-1)/(1-(-1)) = -1.

The slope between points (1, -1 and (3, -4) is a maximum of (-4-(-1))/(3-1) = -3/2.

Thus, as x increases, the slope is decreasing. In order for that to be the case, the value of <em>a</em> must satisfy a < 0.

sergey [27]
8 gallons= 128 cups
20 guests x 2 cups each= 40 cups will be gone
128-40= 88 cups left over
88 cups= 5.5 gallons of punch left at the end of the party.
