A change in demand means that the entire demand curve shifts either left or right. A change in quantity demanded refers to a movement along the demand curve, which is caused only by a chance in price.

The percent P of defective parts produced by a new employee t days after the employee starts work can be modeled by
P = t + 1810/50(t + 2).
Find the rates of change of P at t = 1 and t = 10. (Round your answers to two decimal places.)
Answer:
[tex]\frac{dP}{dt} (1) = -4.02\,\frac{\%}{day}[/tex], [tex]\frac{dP}{dt} (10) = -0.25\,\frac{\%}{day}[/tex]
Step-by-step explanation:
The complete statement is:
The percent [tex]p[/tex] of defective parts produced by a new employee [tex]t[/tex] days after the employee starts work can be modeled by:
[tex]p(t) = \frac{t+1810}{50\cdot (t+2)}[/tex]
Find the rates of change of [tex]p[/tex] at [tex]t = 1[/tex] and [tex]t = 10[/tex] (Round your answer to two decimal places.)
The rate of change of the function is the first derivative of the function in time. By rules of differentiation, we obtain the expression of the rate of change of the percent of defective parts:
[tex]\frac{dP}{dt} = \frac{50\cdot (t+2)-50\cdot (t+1810)}{50^{2}\cdot (t+2)^{2}}[/tex]
[tex]\frac{dP}{dt} = \frac{1}{50\cdot (t+2)}-\frac{t+1810}{50\cdot (t+2)^{2}}[/tex] (1)
The rates of change of P at [tex]t = 1[/tex] and [tex]t = 10[/tex] are, respectively:
[tex]\frac{dP}{dt} (1) = -4.02\,\frac{\%}{day}[/tex]
[tex]\frac{dP}{dt} (10) = -0.25\,\frac{\%}{day}[/tex]
How could you correctly rewrite the equation 4(5 + 3) = 2(22 - 6) using the distributive property?
Answer:
We can correctly rewrite the equation: 4(5+3) = 2(22-6) by distributing each side.
4(5+3) = 2(22-6)
4(8) = 2(16)
32 = 32
Once you finish distributing each side, you can check to see if it is equal on both sides.
Step-by-step explanation:
Step-by-step explanation:
4(5 + 3) = 2(22 - 6)
4(8) = 2(16)
32 = 32

Three landmarks of baseballachievement are Ty Cobb’s batting average of 0.420 in 1911,Ted Williams’s 0.406 in 1941, and George Brett’s 0.390in 1980. These batting averages cannot be compared directly becausethe distribution of major league batting averages has changed overthe years. The distributions are quite symmetric and (except foroutliers such as Cobb, Williams, and Brett) reasonably normal.While the mean batting average has been held roughly constant byrule changes and the balance between hitting and pitching, thestandard deviation has dropped over time. Here are the facts:
Decade
Mean
Standard Deviation
1910s
0.266
0.0371
1940s
0.267
0.0326
1970s
0.261
0.0317
Compute the standard units for the batting averages of Cobb,Williams, and Brett to compare how far each stood above his peers.Who is the better player of the three?
Answer:
Ted Williams has the highest standardized score, hence Williams is the best of the three
Cobb is the second highest and hence, the better player
George Brett is third
Step-by-step explanation:
Given the data:
Decade : 1910 __ 1940 ____ 1970
Mean, μ: 0.266 __0.267 ___ 0.261
S/dev, σ : 0.0371 _ 0.0326 __ 0.0317
To compute the standard unit for batting averages, we obtain the standardized score for each of Cobb,Williams, and Brett.
Standardized score (Zscore) : (x - μ) / σ
Cobb, x = 0.420
Ted Williams, x = 0.406
George Brett, x = 0.390
COBB:
Zscore = (0.420 - 0.266) / 0.0371 = 4.1509
Ted Williams :
Zscore = (0.406 - 0.267) / 0.0326 = 4.2638
George, Brett = (0.390 - 0.261) / 0.0317 = 4.0694
Ted Williams has the highest standardized score, hence Williams is the best of the three
Cobb is the second highest and hence, the better player
George Brett is third
Consider the following food chain:
Plants are eaten by grasshoppers, which are eaten by mice, which are eaten by snakes.
What will happen to the other members of the food chain if the grasshoppers are removed?
a.
the number of plants will increase, the number of mice will decrease, the number of snakes will decrease
b.
the number of plants will decrease, the number of mice will increase, the number of snakes will increase
c.
the number of plants will decrease, the number of mice will increase, the number of snakes will decrease
d.
the number of plants will increase, the number of mice will increase, the number of snakes will increase
Answer:
A
Step-by-step explanation:
the plant will increase because no grasshopper will be present to eat them without the grasshopper the mice cannot eat so the mice population will decrease....
If the grasshoppers are removed then the number of plants will increase, the number of mice will decrease, the number of snakes will decrease.
The correct answer is option a.
For the given Food chain:
If the grasshoppers are removed from the food chain, it will lead to a increase in the number of plants, as there will be no herbivores (grasshoppers) to consume them. This is because grasshoppers help control plant populations by feeding on them.
With the removal of grasshoppers, the mouse population is likely to decrease since their primary food source (grasshoppers) is no longer available.
As a consequence of the decreased mouse population, the snake population may also decrease because their primary food source (mice) has been affected.
Thus, the number of plants will increase, the number of mice will decrease, the number of snakes will decrease.
Thus, option a is correct.

Find the equation of a line parallel to y - 5 = 6x – 10 that passes through the
point (4,10). (answer in slope-intercept form)
Answer:
y=6x-14
Step-by-step explanation:
y=mx+b
m=slope
b=y-intercept
add 5 on both sides to make y on the left side and the other part on the right side.
y=6x-5
IMPORTANT: Parallel lines have the same slope
if the line passes through the point (4,10) we can substitute values for x and y into y=mx+b
10=4m+b
Now since we know that this line is parallel to y=6x-5 they have the same slope which means m is 6
10=4(6)+b
now solve for b
-14=b
so we know that m is 6 and b =14 now we substitute it back into y=mx+b for m and b
y=6x-14
Hope that helps :)

8. Determine the area of a sector
with a central angle of 42° in a
circle with radius 3 inches.
NEED IT ASAP
Answer:
[tex]\boxed {\boxed {\sf A \approx 3.3 \ in^2}}[/tex]
Step-by-step explanation:
Since we are given the central angle in degrees, we should use the following formula for sector area.
[tex]A= \frac {\theta}{360}* \pi r^2[/tex]
The angle is 42 degrees and the radius is 3 inches. Therefore,
[tex]\theta= 42 \\r=3 \ in[/tex]
[tex]A=\frac {42}{360} * \pi (3 \ in)^2[/tex]
Solve the exponent.
(3 in)²= 3 in*3in = 9 in²[tex]A=\frac {42}{360} * \pi (9 \ in^2)[/tex]
Multiply all three numbers together.
[tex]A= 0.116666666667* 3.14159265359 * 9 \ in^2[/tex]
[tex]A=3.29867228627 \ in^2[/tex]
Let's round to the tenth place. The 9 in the hundredth place tells us to round the 2 up to a 3.
[tex]A \approx 3.3 \ in^2[/tex]
The area of the sector is approximately 3.3 square inches.

Answer:
∠C = 75°
Step-by-step explanation:
using the formula for the sum of interior mangles for a polygon:
total interior angles = (180° x 5 angles) - 360° = 540°
113° + 4x + 113° + 2x + 9° + 3x + 8° = 540°
combine like terms:
9x + 243° = 540°
9x = 297°
x = 33°
∠C = 2(33) + 9 = 75°

A right prism has height 8 and triangular bases with sides of length 7, 8, and 9. What is the: Total surface area of the prism?
Answer:
the total surface area of the prism is 245.67
Step-by-step explanation:
Given;
height of the triangular prism, h = 8
length of the triangular bases, = 7, 8, and 9
The total surface area of the prism is calculated as;
T.S.A = ph + 2B
Where;
p is the perimeter of the base
B is area of the base
P = 7 + 8 + 9 = 24
Area of the base can be calculated using Hero's formula;
[tex]S = \frac{7+8+9}{2} = 12\\\\Base \ area (B) = \sqrt{12(12-7)(12-8)(12-9)} = 26.833[/tex]
T.S.A = (24 x 8) + 2 x 26.833
T.S.A = 192 + 53.666
T.S.A = 245.67
Therefore, the total surface area of the prism is 245.67

Calculate the square and the circle and add them together.

[tex]2\pi[/tex]3
Circumference = [tex]2\pi[/tex]r = 2 × [tex]\pi[/tex] × 3 = 18.84956
18.84956 rounds to 18.85
The circle's area is 18.85 un².
The square is 6 by 6.
6 × 6 = 36
The square's area is 36 un².
18.85 un² + 36 un² = 54.85 un²
