the number invisivble in front of x is 1

The correct answer is D, you are right.

Answer:

The answer is D.

Step-by-step explanation:

The inequality pairs with y ≤−2x−1 to complete the system of linear inequalities represented by the graph is y > -2x+2

The one inequality is

y ≤−2x−1

The inequality is represents the relationship between two variables with inequality sign. The inequality will be less than, greater than, less than or equal to and greater than or equal to.

Both lines are parallel therefore the slope of the line will be same that is -2.

The y intercept of the line is +2

The shade is on the top side of the line

Therefore the inequality will be

y>−2x+2

Hence, the inequality pairs with y ≤−2x−1 to complete the system of linear inequalities represented by the graph is y > -2x+2

Step-by-step explanation: I took the test .

(a) First step of implicit differentiation:
-0.82dP/dt = dq/dt
The equation that results from differentiating each side of the equation with respect to P is:
-0.82 - 0.82P(d^2q/dP^2) = (dQ/dP)(dP/dt)/(dq/dt)
To find the elasticity of demand, we need to use the formula:
E = (dQ/Q)/(dP/P)
We can rewrite this as:
E = (dQ/dP) * (P/Q)
We know that dQ/dP = -0.82P(d^2q/dP^2), so we substitute that into the formula:
E = (-0.82P(d^2q/dP^2)) * (P/q)
Simplifying this expression, we get:
E = -0.82P^2(d^2q/dP^2)/q

(b)  We can solve the original equation for q by dividing both sides by -0.82:
q = (-1/0.82)P + D
Taking the derivative of q with respect to P, we get:
dq/dP = -1/0.82
We can use this result to calculate the elasticity of demand using the formula:
E = (dQ/dP) * (P/Q)
Substituting the values we found, we get:
E = (-1/0.82) * (P/((-1/0.82)P + D))
Simplifying this expression, we get:
E = -1/(P/((-1/0.82)P + D))
E = -1/((D/P) - 1.22)

(a) Interpretation: The elasticity of demand is a measure of how much the quantity demanded changes in response to a change in price. If E > 1, demand is considered elastic, meaning that a small change in price will result in a large change in quantity demanded. If E < 1, demand is considered inelastic, meaning that a change in price will result in a small change in quantity demanded. If E = 1, demand is unit elastic, meaning that a change in price will result in an equal proportional change in quantity demanded.
(b) Interpretation: The elasticity of demand in this case depends on the values of D and P. If D is relatively small compared to P, then the elasticity of demand will be close to -1.22, which is the upper limit of the elasticity. If D is relatively large compared to P, then the elasticity of demand will be close to zero, which means that demand is very inelastic.

Answer: 81,000

Step-by-step explanation:

We can solve this by using the formula given.

If f(1)=1000x3^1, then 1,000x3=3,000

If f(2)=1000x3^2, then 3^2=9 and 1000x9=9000,

and so on,

Now, f(4) will equal 1000x3^4, and 3^4 is 3x3x3x3, which is 9x9 or 9^2, which would be equal to 81, and 81x1000=81,000

To complete the table of values for the exponential function f(x) = 1000*3^x, we can evaluate the function for x = 0, 1, 2, 3, and 4, since we are interested in the number of bacteria on the phone after 4 hours.

x f(x)

0 1000

1 3000

2 9000

3 27,000

4 81,000

Therefore, after 4 hours, there will be 81,000 bacteria on the surface of the phone, assuming the number of bacteria triples every hour and can be described by the exponential function f(x) = 1000*3^x.

The midpoint rule is an overestimate.

This is because the midpoint rule is a form of numerical integration which approximates the area under a curve by summing the areas of rectangles that are divided into equal intervals. These rectangles are centered on the midpoints of the intervals.

Because the rectangles are centered on the midpoints instead of the endpoints of each interval, the midpoint rule overestimates the area under the curve as the rectangles are wider than the intervals.

This means that the midpoint rule produces a larger area than the exact area under the curve. This is why the midpoint rule is an overestimate.

The midpoint rule is an overestimate of the definite integral. The midpoint rule is a numerical integration method used to approximate the definite integral of a function.

It works by dividing the interval of integration into smaller subintervals and approximating the integral by summing the areas of rectangles whose heights are determined by the function evaluated at the midpoint of each subinterval.

Since the rectangles in the midpoint rule are taller at the midpoint and shorter at the endpoints, this method generally overestimates the true area under the curve. However, if the function is well-behaved and the subintervals are small enough, the error between the midpoint rule approximation and the true definite integral can be made arbitrarily small.

In conclusion, the midpoint rule is an overestimate of the definite integral, but the error can be made small by using smaller subintervals.

Answer:

The least value of n is 17.

Step-by-step explanation:

First term (a) = 46

Second term (a + d) = 43

Third term (a + 2d) = 40

Common difference (d) = second term - first term = 43 - 46 = -3

Tn (nth term) = a + (n - 1)d

a = 46, d = -3

Tn = 46 + (n - 1)-3 = 46 + (-3n + 3) = 46 - 3n + 3 = 49 - 3n

For Tn to be negative, the product of 3 and n must be greater than 49.

Therefore, the least value of n is 17

Answer:

17

Step-by-step explanation:

AP 46, 43, 40

a₁= 46, a₂= 43, a₃=40

d= a₃-a₂= a₂-a₁= -3

aₙ= 46+(n-1)*(-3)= 46-3n+3= 49- 3n

nth term is negative, so:

The actual area of the closet's floor is 3.52 square meters.

To find the actual area of the closet's floor, we first need to convert the dimensions from the scale drawing to their actual dimensions.

According to the given scale, 2 cm on the scale drawing represents 1 meter in reality. Thus, to convert the dimensions from the scale drawing to actual dimensions, we need to multiply each dimension by the conversion factor:

Actual length = 4.4 cm × (1 m / 2 cm) = 2.2 m

Actual width = 3.2 cm × (1 m / 2 cm) = 1.6 m

Now that we have the actual dimensions, we can calculate the actual area of the closet's floor:

Actual area = Actual length × Actual width

= 2.2 m × 1.6 m

= 3.52 square meters

Therefore, the actual area of the closet's floor is 3.52 square meters.

Answer:

97.96 inches squared

Step-by-step explanation:

Finding the length of all the sides of the square painting.

Área = lenght × Breath

Area = 600

(because it's a square all sides are equal meaning length is equal to breath thus representing them with L in the equation length × breath = L × L = L² )

600 = L²

taking roots of both sides.

√600 = √L²

24.49 = L

thus each side of the square painting is relatively 24.49 square inches

solving for Perimeter :

Perimeter of a square is given as = 4×L

(where L is representing the length of any of the sides because they are equal.)

but, L = 24.49

thus ;

Perimeter = 24.49 × 4

= 97.96 inches squared.

The elevation of the curve at station 21+33 is 499.8 ft.

To find the elevation of the curve at station 21+33, we need to consider the vertical curve and its characteristics. Given that the back tangent has a grade of -1.8% and the forward tangent has a grade of 2.6%, we can calculate the rate of change in elevation per foot of curve (RC).

RC = (forward grade - back grade) / curve length

RC = (2.6% - (-1.8%)) / 1230 ft

RC = 4.4% / 1230 ft

RC = 0.003577 ft/ft

Next, we need to calculate the elevation of the curve at station 21+33. To do this, we first determine the distance from VPC to station 21+33.

Distance from VPC to station 21+33 = (21+33) - (16+01) = 5+32 = 532 ft

Using the RC, we can calculate the change in elevation from VPC to station 21+33.

Change in elevation = RC x Distance

Change in elevation = 0.003577 ft/ft x 532 ft

Change in elevation = 1.902 ft

Finally, we add the change in elevation to the elevation of the VPC to get the elevation at station 21+33.

Elevation at 21+33 = VPC elevation + Change in elevation

Elevation at 21+33 = 496.2 ft + 1.902 ft

Elevation at 21+33 = 499.8 ft

Therefore, the elevation of the curve at station 21+33 is 499.8 ft.

We are 95% confident that the true proportion of healthy students who could correctly identify a Skittles flavor blindly lies within the interval (0.4282, 0.5848).

To find the confidence interval, we can use the formula:

CI = p ± zsqrt(p(1-p)/n)

Where:

CI: Confidence Interval

p: Proportion of students who correctly identified the flavor (sample proportion)

z: Z-score corresponding to the desired confidence level (95% confidence level corresponds to z=1.96)

n: Sample size

Plugging in the values we have:

p = 78/154 = 0.5065

z = 1.96

n = 154

CI = 0.5065 ± 1.96sqrt(0.5065(1-0.5065)/154)

CI = 0.5065 ± 0.0783

CI = (0.4282, 0.5848)
