Find the average rate of change of f(x)=2x^2-7x from x=2 to x=5

Mathematics
1 answer:
m_a_m_a [10]3 years ago
3 0

Answer:

7

Step-by-step explanation:

The average rate of change of f(x) in the close interval [ a, b ] is

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

Here [ a, b ] = [2, 5 ]

f(b) = f(5) = 2(5)² - 7(5) = 50 - 35 = 15

f(a) = f(2) = 2(2)² - 7(2) = 8 - 14 = - 6, thus

average rate of change = \frac{15-(-6)}{5-2} = \frac{21}{3} = 7

Solve 50r − 6 = 82r − 70
Basile [38]

Answer:

Step-by-step explanation: 50r - 6= 82r-70

Add 50r to 82r which equals to 132 r

Now add the the 70 to the left side so -6+70 should equal 76.

Now it should look like this 76=132r

To get the value of r you have to divide 76/132 on both sides of the equation and your answer should be 0.57=r

mafiozo [28]

Answer:

L=132.66

36.18=W

Step-by-step explanation:

length=L

width=W

Area=A

A=L×W

L=11/3W

4800=11/3W×W

4800=11/3W²

3/11·4800=11/3W²·3/11

√1309.1=√W²

36.18=W

L=11/3×36.18

L=132.66

All answers are approximated.

Which equation, in slope-intercept form, passes through (–2, 4) and has a
kipiarov [429]

Answer:

y=3x+10

Step-by-step explanation:

First, put the equation into point-slope form.

y-y1=m(x-x1)

y-4=3(x+2)

Next, distribute 3 to (x+2) and simplify.

y-4=3x+6

y=3x+10

Determine the equation of a circle with center at (8, 10) and radius 6.
andreev551 [17]

Answer:

Step-by-step explanation:

general equation for a circle at the origin is

x² + y² = r²

if the circle center is (x₀, y₀), the formula is

(x - x₀)² + (y - y₀)² = r²

(x - 8)² + (y - 10)² = 36
