Answer:

Step-by-step explanation:

Given

C=5x+4y
x≤-2

x≥-4

y≥1
y≤6

Here we are asked to find the maximum value of C

C is a sum of factors of x and y

As both the co-efficients of x and y are positive, we have to select the maximum values of both in their given ranges

(if any of their co-efficients was negative, the term whose co-efficient is negative is to be substituted with its least value in its range to get maximum value of C)

Therefore Maximum value of x=-2 and y=6

therefore C

$= 5\times -2 + 4\times 6\\= -10 + 24\\= 14$

Therefore maximum value of C=14

If you are good at sequences in math please help I am giving more points

Nat2105 [25]

Answer:

-3, -7, -23, -87, and -343

Step-by-step explanation:

Here, we're given that the sequence is $a_n=4a_{n-1}+5$ , where n indicates the nth term and n - 1 indicates the (n - 1)th term.

$a_1=-3$ , so if we want to find $a_2$ , we can say n = 2 and n - 1 = 1:

$a_2=4a_{1}+5=4*(-3)+5=-12+5=-7$

We continue to do this to find $a_3,a_4,$ and $a_5$ :

$a_3=4a_{2}+5=4*(-7)+5=-28+5=-23$

$a_4=4a_{3}+5=4*(-23)+5=-92+5=-87$

$a_5=4a_{4}+5=4*(-87)+5=-348+5=-343$

Thus, the first 5 terms in the sequence are:

-3, -7, -23, -87, and -343

Hope this helps!

What is the value of f(4) + f(7)

tatyana61 [14]

Is there more to this problem? By saying f(4), you'd be inputting a 4 for every variable x. There is not enough info here to answer the question.

Calculate the volume of the cylinder, where a = 18 and b = 11. Use 3.14 for pi and round your answer to the nearest tenth.

cupoosta [38]

Answer:

Volume of cylinder $=2797.7$

Step-by-step explanation:

Let $a$ be diameter and $b$ the height of the cylinder

$Then\ radius(r)=\frac{diamater\ (a)}{2}\\\\r=\frac{18}{2}\\\\r=9$

Volume of cylinder $=\pi\times(radius)^2\times(height)$

$=\pi\times(9)^2\times11\ \ \ \ \ \ (\pi=3.14)\\\\=3.14\times9\times9\times11\\\\=2797.74\\\\\approx2797.7$

PLEASE HELP ME!!!!!!!!!!! PLZ

irina1246 [14]

Answer:

1/16

Step-by-step explanation:

1/2 divided by 8= 0.0625

There is not much that can be done to figure out how to write 0.0625 as a fraction, except to literally use what the decimal portion of your number, the .0625, means.

Since there are 4 digits in 0625, the very last digit is the "10000th" decimal place.

So we can just say that .0625 is the same as 0625/10000.

The fraction is not reduced to lowest terms. We can reduce this fraction to lowest

terms by dividing both the numerator and denominator by 625.

Why divide by 625? 625 is the Greatest Common Divisor (GCD)

or Greatest Common Factor (GCF) of the numbers 625 and 10000.

So, this fraction reduced to lowest terms is

So your final answer is: 1/16
