Angle BEC is congruent to angle DEC. The student's error lies in assuming that BC + CD = 2BC means that AB = 2BC, which is incorrect. The student concluded that AB = 2BC by incorrectly analyzing the given diagram.

The error can be explained as follows: Since EB is the perpendicular bisector of AD, AB = BD is true.

Angle BEC is congruent to angle DEC, which makes BC = CD true.

If BC + CD is added, it equals BD, which is also equal to AB. Consequently, BC + CD = AB. Also, BC + CD can be written as BC + BC = 2BC.

However, this does not imply that AB = 2BC, as the student incorrectly concluded.

It is because BC and CD are two separate line segments, and just because they have the same length does not imply that they add up to double their length.

So, the student's error lies in assuming that BC + CD = 2BC means that AB = 2BC, which is incorrect.

The probability of randomly meeting a three-child family with either exactly one or exactly two boy children is 3/4.

The events described are non-overlapping. Let E be the event of randomly meeting a three-child family with exactly one boy child.

Let F be the event of randomly meeting a three-child family with exactly two boy children.

P(E) = probability of meeting a family with exactly one boy child

P(F) = probability of meeting a family with exactly two boy children

Given that the events E and F are non-overlapping.

So, we can use the formula of either/or probability:

P(E or F) = P(E) + P(F)P(E or F)

= probability of meeting a family with exactly one or two boy children

P(E or F) = P(E) + P(F)P(E or F)

= (number of ways to get a family with exactly one boy child) / (total number of three-child families) + (number of ways to get a family with exactly two boy children) / (total number of three-child families)

P(E or F) = (3 * 2 * 1) / (2 * 2 * 2 * 3) + (3 * 2 * 1) / (2 * 2 * 2 * 3)

P(E or F) = 6/8

P(E or F) = 3/4

The unit rate that fertilizer cover is 3/2 square foot.

The unitary technique involves first determining the value of a single unit,  followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

A fertilizer covers 3/4 square foot in 1/2 hour.

So, unit rate fertilizer covers

Answer:

(g · h)(5) = -50

Step-by-step explanation:

Step 1: Define

h(x) = x - 7

g(x) = x²

Step 2: Find (g · h)(x)

(g · h)(x) = x²(x - 7)

(g · h)(x) = x³ - 7x²

Step 3: Find (g · h)(5)

(g · h)(5) = 5³ - 7(5)²

(g · h)(5) = 125 - 7(25)

(g · h)(5) = 125 - 175

(g · h)(5) = -50

The given focus point is (−3,3), and the directrix equation is y=7.Let P(x,y) be any point on the parabola. The perpendicular distance of P from directrix is y-7. Similarly, distance between point P and the focus is PF.

See the diagram below, to understand the scenario:As the parabola is symmetric about the directrix, the distance between the point P and directrix is equal to the distance between the focus and the point P.So, the distance PF is equal to y−7. Using the distance formula, find PF:PF =  [(x−(−3))^2 + (y−3)^2]^(1/2)PF^2 = (x+3)^2 + (y−3)^2

Next, use the definition of the parabola and substitute PF^2 = 4a(y−k),where (h,k) are the vertex and a is the distance between the vertex and focus. Thus, the vertex is (-3,5) (as the directrix is y=7), a = 2 (PF = 2), and the equation of the parabola can be expressed in the form y = a(x−h)^2 + k.y = 1/8(x+3)^2- 5Thus, the required equation of the parabola is y = 1/8(x+3)^2- 5.

Answer:

x is less than or equal to 4

Step-by-step explanation:

Answer:

x is less than or equal to 4

Step-by-step explanation:

The inequality shown is the less than or equal to sign

a. the equation for the object's velocity is v(t) = -6 cos(t) - 1. b. the total distance traveled by the object from time 0 to time t is 6 sin(t) + t meters.

a) To find the equation for the object's velocity, we need to integrate the acceleration function with respect to time.

The integral of a(t) = 6 sin(t) with respect to t gives us the velocity function v(t):

v(t) = ∫(6 sin(t)) dt

Integrating sin(t) gives us -6 cos(t), so the equation for the object's velocity is:

v(t) = -6 cos(t) + C

To find the constant C, we use the initial velocity v(0) = -7 m/s:

-7 = -6 cos(0) + C

-7 = -6 + C

C = -1

Therefore, the equation for the object's velocity is:

v(t) = -6 cos(t) - 1

b) To find the object's displacement from time 0 to time 3, we need to integrate the velocity function over the interval [0, 3]:

Displacement = ∫[0,3] (-6 cos(t) - 1) dt

Integrating -6 cos(t) gives us -6 sin(t), and integrating -1 gives us -t. Applying the limits of integration, we have:

Displacement = [-6 sin(t) - t] from 0 to 3

Plugging in the upper and lower limits:

Displacement = [-6 sin(3) - 3] - [-6 sin(0) - 0]

Displacement ≈ -6 sin(3) + 3

Therefore, the object's displacement from time 0 to time 3 is approximately -6 sin(3) + 3 meters.

c) To find the total distance traveled by the object from time 0 to time t, we need to integrate the absolute value of the velocity function over the interval [0, t]:

Total Distance = ∫[0,t] |(-6 cos(t) - 1)| dt

Since the absolute value function makes the negative part positive, we can rewrite the equation as:

Total Distance = ∫[0,t] (6 cos(t) + 1) dt

Integrating 6 cos(t) gives us 6 sin(t), and integrating 1 gives us t. Applying the limits of integration, we have:

Total Distance = [6 sin(t) + t] from 0 to t

Plugging in the upper and lower limits:

Total Distance = [6 sin(t) + t] - [6 sin(0) + 0]

Total Distance = 6 sin(t) + t

Therefore, the total distance traveled by the object from time 0 to time t is 6 sin(t) + t meters.

The Annual Percentage Yield (APY) for the savings account with an APR of 6.2% and monthly compounding is approximately 6.22%.

To calculate the Annual Percentage Yield (APY) for a savings account that compounds monthly, we can use the following formula:

APY = (1 + r/n)^n - 1

Where:

r is the annual interest rate expressed as a decimal (6.2% = 0.062)

n is the number of times the interest is compounded per year (monthly compounding = 12)

Let's plug in the values and calculate the APY:

APY = (1 + 0.062/12)^12 - 1

APY = (1.0051667)^12 - 1

APY ≈ 0.062161 (rounded to five decimal places)

To convert the APY to a percentage and round it to two decimal places, we multiply the result by 100:

APY ≈ 6.22%

Therefore, the Annual Percentage Yield (APY) for the savings account with an APR of 6.2% and monthly compounding is approximately 6.22%. This indicates the effective annual rate of return you would earn on your savings, taking into account the compounding of interest over the course of a year.

To evaluate the limit of f(x) as x approaches 3 from the left, we substitute the value of x that is slightly less than 3 into the first part of the piecewise function. Therefore[tex], lim f(x)[/tex]as x approaches 3- is equal to lim (3 - 2 + x) as x approaches 3-. Simplifying further, we get lim f(x) as x approaches 3- = 3 - 2 + 3 = 4.

To evaluate the limit of f(x) as x approaches 3 from the right, we substitute the value of x that is slightly greater than 3 into the second part of the piecewise function. Therefore, lim f(x) as x approaches 3+ is equal to lim (4 - x) as x approaches 3+. Simplifying further, we get lim f(x) as x approaches 3+ = 4 - 3 = 1. Now, to determine whether the function f is continuous at x = 3, we compare the left-hand limit[tex](lim f(x)[/tex]as x approaches 3-) and the right-hand limit [tex](lim f(x)[/tex] as x approaches 3+).

If the two limits are equal and the function value at x = 3 (f(3)) is equal to the limits, then the function is continuous at x = 3. In this case, the left-hand limit is 4, the right-hand limit is 1, and the function value at x = 3 is not given. Since the left-hand and right-hand limits are not equal, the function f is not continuous at x = 3.
