Find the derivatives.
f ' (0) exists if the limit,
[tex]\displaystyle \lim_{h\to0}\frac{f(0+h)-f(0)}h[/tex]
exists, and f ' (0) has the value of this limit.
In order for this limit to exist, both limits from either side of h = 0 must exist.
Suppose h < 0. Then 0 + h is also negative, so by definition of f(x) we have
f (0 + h) = ((0 + h) + 1)² = h ² + 2h + 1
Then in the limit, if h is approaching 0, it must be from below or from the left:
[tex]\displaystyle \lim_{h\to0^-}\frac{f(0+h)-f(0)}{h} = \lim_{h\to0^-}\frac{(h^2+2h+1)-1}{h} = \lim_{h\to0^-}(h+2) = 2[/tex]
Now suppose h > 0, so that 0 + h is positive and h approaches 0 from above or from the right. Then
f (0 + h) = 2 (0 + h) + 1 = 2h + 1
and
[tex]\displaystyle \lim_{h\to0^+}\frac{f(0+h)-f(0)}h = \lim_{h\to0^+}\frac{(2h+1)-1}{h} = \lim_{h\to0^+}2 = 2[/tex]
Both one-sided limits match, so f ' (0) = 2.
A certain drug is made from only two ingredients: compound A and compound B. There are 3 milliliters of compound A used for every 5 milliliters of compound B. If a chemist wants to make 408 milliliters of the drug, how many milliliters of compound A are needed?
Answer:
153
Step-by-step explanation:
The formula is 3 mL of A to 5 mL of B.
Let's say the chemist uses just the numbers in the formula.
Add 3 mL of A to 5 mL of B.
3 mL + 5 mL = 8 mL
The chemist ends up with 8 mL of the drug.
He really want 408 mL.
408 mL is how many times greater than 8 mL?
408/8 = 51
He needs to use 51 times the numbers in the formula.
51 * 3 mL of A + 51 * 5 mL of B =
= 153 mL of A + 255 mL of B
= 408 mL of the drug

Step-by-step explanation:
In the diagram shown, C is the midpoint of BD. What is the
length of AC?
Set up an equation based on the given information, solve
for x, and plug answer back in to answer the question
Answer:
AC = 20
Step-by-step explanation:
C is the midpoint of BD.
That means that BC = CD
BC = x + 4
CD = 3x - 10
x + 4 = 3x - 10 Subtract x from both sides
4 = 3x - x - 10 Combine
4 = 2x - 10 Add 10 to both sides
4 + 10 = 2x - 10 + 10 Combine
14 = 2x Divide by 2
14/2 = 2x/2 Combine
7 = x
AC = AB + BC
AC = 2x - 5 + x + 4
AC = 3x - 1
AC = 3*7 - 1
AC = 21 - 1
AC = 20
If g(3) = 5 and g(-1) = 5, explain why g(x) does not have an inverse.
g(x) cannot have an inverse because it gives the same output value for two individual input values.
In this case, g(x) is 5 when x is both 3 and -1. Hence, g(x) does not have an inverse.

Question 4: In a certain organization 20% of the men and 40% of the women attended. the program review meeting that was held in Abuja last Dec 2018. If 35% of all the employees are men. What % of all the employee went to the program review meeting?
Answer:
.33
Step-by-step explanation:
m=male
f=female
a=attended the review
P(A|M)= .2
P(A|F)= .4
We want: F∩A+M∩A
Recall the conditional probability formula (A|B)=(A∩B)/B
.2*.35+.4*.65= .33
Ahmed bought 5 equally priced markers for $3.25.
How much will 12 of these markers cost?
$1.35
$6.68
$7.80
$8.46
Answer:
$7.80
Step-by-step explanation:
Find the unit price by dividing 3.25 by 5.
3.25 ÷ 5 = 0.65
Now that you have the unit price, multiply it by 12 to find the total price of the 12 markers.
0.65 × 12 = 7.80
Thus, 12 of the same markers that Ahmed bought will cost $7.80.
The cost of 12 markers is given by the equation A = $ 7.80
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
Let the number of markers be n = 5
The cost of 5 markers = $ 3.25
So , the cost of 1 marker = cost of 5 markers / 5
On simplifying the equation , we get
The cost of 1 marker = 3.25 / 5
The cost of 1 marker = $ 0.65
Now , the cost of 12 markers = 12 x cost of 1 marker
Substituting the values in the equation , we get
The cost of 12 markers A = 12 x $ 0.65
The cost of 12 markers A = $ 7.80
Hence , the equation is A = $ 7.80 , where A is the total cost of markers
