Answer:

Bottom left graph

Step-by-step explanation:

Given function:

y = -x^3 + ax^2 + bx + c

This is a third degree function with negative leading coefficient.

This is therefore decreasing function and can have one local maximum and one local minimum.

From the given graphs we can see only bottom left one can be a matching one.

MARKING AS BRAINLIEST!! (Geometry)

Answer:

x = 15.49

Step-by-step explanation:

As you can see this is a right-angled triangle due to the right angle symbol, we can use Pythagorean theory to find the unknown length:

$a^2 + b^2 = c^2$

In this case, we know C and B but not A so:

$a^2 = c^2 - b^2$

Now plug the values in:

$a^2 = 16^2 - 4^2$

$a^2 = 256 - 16$

$a^2 = 240$

Square root the answer to get A:

$a = \sqrt{240}$

a = 15.49

x = 15.49

Hope this helps!

Nadya [2.5K]

Answer:

The last guy's height is 69 inches

Step-by-step explanation:

mean=sum of all numbers/number of numbers

There are 5 numbers in the set which means that 65 is the sum of all five numbers divided by 5. To reverse that we multiply 65 by 5 to get the sum of all of the numbers.

$65*5=325$

325 is the sum of all of the numbers so to find the missing number you add up all of the known numbers in the set and find the difference between that sum and 325.

$60+67+65+64=256$

$325-256=69$

The missing guy's height is 69 inches.
