What is the average rate of change for the function f(x)=3(0.25)^x over the interval -2 ≤ x ≤ 0
diamong [38]
Answer:
-22.5


Explanation:
Use the average rate of change equation
f(b)-f(a) / b-a
f(b) = f(0) = 3(.25)^0 = 3
f(a) = f(-2) = 3(.25)^-2 = 48

(3-48)/ 0-(-2)
(-45) / 2
-22.5

\huge \boxed{\mathfrak{Question} \downarrow}

  • Evaluate the expression when c = 21 and d = 4, c - 5d = ?

\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}

Given,

  • c = 21
  • d = 4
  • c - 5d = ?

Let's solve it now :-

\sf \: c - 5d \\  \\  \sf \: Substitute \: the \: values \: of \: c \: and \: d \\  \\ \sf c - 5d \\  \rightarrow \sf(21) - 5(4) \\ \sf  \rightarrow21 - 20 \\  =    \boxed{\boxed{\bf \: 1}}

  • The value of the expression is <em><u>1</u></em><em><u>.</u></em>

Please help me! Thanks!
Lena [83]
Answer is 9

A(x)=f(b)-f(a)/b-a

where a=-10 b=10
f(x)= x^2+9x+18

f(a)=(-10)^2-90+18=28
f(b)=208
A(x)=208-28/10+10
A(x)=180/20=9

What is the length of side AC of the triangle?<br><br> Enter your answers in the boxes.
inessss [21]

Answer:

AC=25

Step-by-step explanation:

From the given figure, it can be seen that {\angle}A={\angle}C, thus ΔABC is an isosceles triangle.

Therefore,AB=BC

⇒5x+5=7x-1

Solving the above equation, we get

⇒5x-7x=-1-5

⇒-2x=-6

⇒x=3

Now, substituting the value of x in AC, we have

⇒AC=6x+7

⇒AC=6(3)+7

⇒AC=18+7

⇒AC=25

Thus, the length of the side AC of the given triangle is 25 units.
