2 answers:

8 0

The circumference of a circle is expressed as:

Circumference = 2 x pi x r

where r is the radius of the circle and is equal to half of the diameter.

25000 miles = 2 x 3.14 x r
r = 3980.89 miles
r = 7961. 8 miles

The best answer from the choices is B.

(1 point) Consider the function f(x)=2x3−6x2−48x+5 on the interval [−4,10]. Find the average or mean slope of the function on th

andreyandreev [35.5K]

Answer:

The mean slope on the interval is 68

Step-by-step explanation:

The formula to find the mean slope on an interval [a, b] is given by:

$\frac{f(b)-f(a)}{b-a}$

So now, we are going to find f(10) and f(-4) and will substitute these values in the formula.

$f(10)=2(10)^{3} -6(10)^{2} -48(10)+5\\f(10) =2(1000)-6(100)-480+5\\f(10)=2000-600-480+5\\f(10)=925\\\\f(-4)=2(-4)^{3} -6(-4)^{2} -48(-4)+5\\f(-4)=2(-64)-6(16)+192+5\\f(-4)=-128-96+192+5\\f(-4)=-27$

So the mean slope of the function on the interval [-4,10] is:

$\frac{f(10)-f(-4)}{10-(-4)} =\frac{925-(-27)}{14} =\frac{925+27}{14} =\frac{952}{14} =68$

The sum of three numbers is 113 . The second number is 3 times the third. The first number is 7 less than the third . What are t

OLga [1]

Number 1 = 17
number 2 = 72
number 3 = 24

work:

the three numbers are symbolized as x, y, and z

x + y + z = 113

number 2 (y) is 3 times the third number (z) so

y = 3z

so x + 3z + z = 113

the first number (x) is 7 less than than the third number (z) so

x = z - 7

so z -7 + 3z + z = 113

5z - 7 = 113
5z = 120

z = 24

x = 17
y = 72

Hope this helped :)
