find all values of c in the open interval (a, b) such that f'(c)=(f(b)-f(a))/(b-a)
f(x)=√(4-x), [-5,4]
================================================
Work Shown:
Compute the function value at the endpoints
[tex]f(x) = \sqrt{4-x}\\\\f(-5) = \sqrt{4-(-5)} = 3\\\\f(4) = \sqrt{4-4} = 0\\\\[/tex]
With a = -5 and b = 4, we have
[tex]f'(c) = \frac{f(b)-f(a)}{b-a}\\\\f'(c) = \frac{f(4)-f(-5)}{4-(-5)}\\\\f'(c) = \frac{0-3}{9}\\\\f'(c) = -\frac{1}{3}\\\\[/tex]
So,
[tex]f(x) = \sqrt{4-x}\\\\f'(x) = -\frac{1}{2\sqrt{4-x}}\\\\f'(c) = -\frac{1}{3}\\\\-\frac{1}{2\sqrt{4-c}} = -\frac{1}{3}\\\\[/tex]
Use algebra to solve for c
[tex]-\frac{1}{2\sqrt{4-c}} = -\frac{1}{3}\\\\\frac{1}{2\sqrt{4-c}} = \frac{1}{3}\\\\3 = 2\sqrt{4-c}\\\\2\sqrt{4-c} = 3\\\\\sqrt{4-c} = \frac{3}{2}\\\\4-c = \frac{9}{4}\\\\c = 4-\frac{9}{4}\\\\c = \frac{16-9}{4}\\\\c = \frac{7}{4}\\\\[/tex]

Find the 52nd term of the arithmetic sequence-8, -12, -16,...
Answer:
-212
Step-by-step explanation:
This question seems to be incrementing by steps of -4, starting at -8. To get the 52'nd term, we can simply start at the first term and add that -4 51 more times.
Assuming that negative eight is the first term then, we get:
-8 - 4 * 51
= -8 - 204
= -212
The 52nd term of the sequence will be -212.
What is a sequence?A sequence of events or things is a number of events or things that come one after another in a particular order.
Given a sequence, -8, -12, -16,...
nth term of a sequence is given by
an = a + (n-1)*d
a(-212) = -8 + (52-1)*-4
a(-212) = -8-204
a(-212) = -212
Hence, The 52nd term of the sequence will be -212.

8x-9+53=180 solve for x
Answer:
x=17
Step-by-step explanation:
1: Simplify both sides of the equation.
8x−9+53=180
8x+−9+53=180
(8x)+(−9+53)=180(Combine Like Terms)
8x+44=180
8x+44=180
2: Subtract 44 from both sides.
8x+44−44=180−44
8x=136
3: Divide both sides by 8.
(8x=136 )/8

Suppose 2a-3b = -23. Given that a and b are consecutive integers and a
Answer:
a = 20 and b = 21
Step-by-step explanation:
Given:
2a-3b = -23
a and b are consecutive
Find:
a and b
Computation:
a = b - 1
So,
2a-3b = -23
2(b-1)-3b = -23
2b - 2 - 3b = -23
-b = -21
b = 21
So
a = b - 1
a = 21-1
a = 20

Answer:
The correct choice is:
-2 to the 4th power is positive 16.
Option C is correct.
Step-by-step explanation:
We need to find mistake make in work below:
[tex](-2x^4)^4=-16x^{16}[/tex]
The mistake here is when we have even power, the negative sign gets positive i.e [tex](-a)^m=a^m[/tex] if m is even
so, in our case it would be:

The measure of ∠BCD is 145°. The measure of ∠ABC is 65°.
What is measure of ∠BAC?
115°
35°
80°
145°
Answer:
m∠BAC = 80°Step-by-step explanation:
m∠BCD = 145° ⇒ m∠BCA = 180° - 145° = 35°
From ΔABC:
m∠ABC + m∠BCA + m∠BAC = 180°
65° + 35° + m∠BAC = 180°
m∠BAC = 180° - 100°
m∠BAC = 80°

1.Samantha sells ostrich eggs for $2 each and goose eggs for 0.50. For every dollar she earns, she spends $0.10 on feed. If she sells 5 ostrich eggs and 20 goose eggs, how much money does she have left after buying feeds
Answer:
$18
Step-by-step explanation:
Sales price of each ostrich egg = $2
Sales price of each goose egg = $0.50
Amount spent after every dollar earned = $0.10
Number of ostrich eggs sold = 5
Number of goose eggs sold = 20
To find:
Total money left after the feeds are bought?
Solution:
First of all, let us find the total money earned by Samantha.
Money earned by selling ostrich eggs = [tex]2\times 5[/tex] = $10
Money earned by selling goose eggs = [tex]20\times 0.50[/tex] = $10
Total money earned by selling both the eggs = 10+10 = $20
Money spent on feeding on every $1 = $0.10
Money spent on feeding on every $20 = 0.10 [tex]\times[/tex] 20 = $2
Total money left after buying feeds = $20 - $2 = $18

An angle's measure is 43 less than 6 times the measure of its
complement. Find the measure of both angles,
Step-by-step explanation:
A = 6(90-A)-43 Simplify and solve for A.
A = 540-6A-43
A = 497-6A Add 6A to both sides.
7A = 497 Divide both sides by 7.
A = 71 degrees
The complement of A = 90-A = 09-71 = 19

Write an equation of the line that passes through (-4,3) and (0,6
)
Answer:
y=¾+8
Step-by-step explanation:
Using the approach y-y1=m(x-x1),where m is the slope defined by ∆y/∆x
So ∆y/∆x=y2-y1/x2-x1
m=6-3/0-(-4)
m=¾
Now plug in m=¾ into the approach and simplify
y-3=¾(x-(-4))
y-3=¾(x+4) Multiply through by 4
4y-12=3x+12 Transpose it for y
4y=3x+12+12
4y=3x+24 divide through by 4
y=¾+8

There is a bag with only red marbles and blue marbles.
The probability of randomly choosing a red marble is 2/7
There are 16 red marbles in the bag and each is equally likely to be chosen.
Work out how many marbles in total there must be.
Answer: 56
Step-by-step explanation:
Given that :
Marbles in bag are only red and blue ;
Probability of randomly choosing a red = 2/7
Number of red marbles in bag = 16
The total Number of marbles =?
P(choosing a red marble) = required outcome / Total possible outcomes
Required outcome = number of red marbles
Total possible outcomes = total number of blue and red marbles
Total number of blue and red marbles = x
P(choosing a red marble) = required outcome / Total possible outcomes
2/7 = 16 / x
Cross multiply
2x = 16 * 7
2x = 112
x = 112 / 2
x = 56 marbles
Total number of marbles = 56

Steve Conway wants his team to win more than 57 games this year. His team has already won 2 games this season and there are 5 more months to play. Based on his goal, how many games must his team win per month? Write answer as an inequality.
Answer:
11
Explanation:
Because 57 minus 2 games already equals 55, so 55 games divided by 5 months equals 11, so 11 games each month will get u to 57.
The number of games must his team win per month will be;
⇒ x > 11
What is Inequality?
A relation by which we can compare two or more mathematical expression is called an inequality.
Given that;
Steve Conway wants his team to win more than 57 games this year.
And, His team has already won 2 games this season and there are 5 more months to play.
Now,
Let number of games must his team win per month = x
So, We can formulate the inequality as;
⇒ 5x + 2 > 57
Solve for x as;
⇒ 5x > 57 - 2
⇒ 5x > 55
⇒ x > 11
Thus, The number of games must his team win per month will be;
⇒ x > 11
