If the area of a parallelogram is ​(x Superscript 4 Baseline minus 22 x squared plus 12 x minus 15​) square centimeters and its
aksik [14]

Answer:

The height of the parallelogram is Height=x^3 - 5 x^2 + 3 x - 3 cm.

Step-by-step explanation:

Given information:

Area=x^4-22x^2+12x-15 cm²

Base=x+5 cm

The formula for area of a parallelogram is

Area=Base\times Height

Divide both sides by base.

\frac{Area}{Base}=Height

Height=\frac{x^4-22x^2+12x-15}{x+5}

Using synthetic method we get

Height=x^3 - 5 x^2 + 3 x - 3

Therefore the height of the parallelogram is Height=x^3 - 5 x^2 + 3 x - 3 cm.

Why are points and lines hard to define?
Sliva [168]
Because when we draw a point ,we draw a very very small line....one can see how this might lead to a problem.consider a line that is 1 inch long,what we want to looked at 1/1000 through that line it would still be a line.but,if we drew it ,it would look like a point....

Let ​ f(x)=x^2−10x−11 ​. <br> Enter the x-intercepts of the quadratic function in the boxes.
irinina [24]

ANSWER

The y-intercept is (0,-11)

The x-intercepts are:

(-1,0) and (11,0)

EXPLANATION

The given function is

f(x) =  {x}^{2}  - 10x - 11

To find the y-intercept, we put x=0 into the function.

f(0) =  {0}^{2}  - 10(0) - 11

f(0) =  - 11

The y-intercept is (0,-11)

To find the x-intercepts, we put f(x)=0.

{x}^{2}  - 10x - 11 = 0

(x + 1)(x - 11) = 0

This implies that,

x =  - 1 \: or \: x = 11

The x-intercepts are:

(-1,0) and (11,0)

Shan's dumpling house can produce 100 dumplings using one worker and 175 dumplings using two workers. what is the marginal produ
taurus [48]
Marginal product is defined as the incremental change in output that occurs due to a change in the input signals.

It is calculated on two steps:
1- Find the change that occurred to the outputs
2- Divide this change by the additional inputs

For the problem we have here:
Step 1:
old output = 100 dumplings
new output = 175 dumplings
change that occurred = 175 - 100 = 75
Step 2:
This change occurred as a result of adding 1 worker
Therefore:
marginal product = 75/1 = 75
