Answer:

2.55

Step-by-step explanation:1

Convert 1121\frac{1}{2}1​2​​1​​ to improper fraction. Use this rule: abc=ac+bca \frac{b}{c}=\frac{ac+b}{c}a​c​​b​​=​c​​ac+b​​.

34+3.3−1×2+12\frac{3}{4}+3.3-\frac{1\times 2+1}{2}​4​​3​​+3.3−​2​​1×2+1​​

2

Simplify 1×21\times 21×2 to 222.

34+3.3−2+12\frac{3}{4}+3.3-\frac{2+1}{2}​4​​3​​+3.3−​2​​2+1​​

3

Simplify 2+12+12+1 to 333.

34+3.3−32\frac{3}{4}+3.3-\frac{3}{2}​4​​3​​+3.3−​2​​3​​

4

Simplify.

the function g(x) Is the graph below resulted from shifting the graph of f(x) down 2 units. If f’(2)=8, what is g’(2)?
Sauron [17]

We know that the graph of g(x) is the result of a shift of 2 units down from f(x).

Then, f(x) and g(x) are related by:

g(x)=f(x)-2

Taking the derivative:

g^{\prime}(x)=f^{\prime}(x)

This is because the derivative of a constant number is 0. Finally, evaluating at x = 2:

\begin{gathered} g^{\prime}(2)=f^{\prime}(2) \\  \\ \therefore g^{\prime}(2)=8 \end{gathered}

(b) The area of a rectangular pool is 5488 m\2 If the length of the pool is 98 m, what is its width?​
mrs_skeptik [129]

Answer:

56

Step-by-step explanation:

To find the area of a rectangle we have the foruma A=WxL.

But we already have the area and length so we can plug that in

5488=Wx98

Now its an algebreic expression.

SInce its multiplying we do the opposite, so we divide 98 on both sides.

98/98 crosses itself out so now its 5488/98. Which equals 56. So now our expression is W=56. To fact check we put the numbers 56 and 98 into the formula to see if we get 5488.

A=56x98

A=5488
