Answer:
The answer would be A/B=H
Step-by-step explanation:
To get rid of the B that is connected to the H, you would do the opposite of what they used. Meaning since the two were multiplied you would divide them. So, you would take your b and divide it on both sides of the equal sign. B and B cancels each other out so you are left with A/B which equals H.

The acceleration of an object (in m/s2) is given by the function a(t) = 6 sin(t). The initial velocity of the object is v(0) = -7 m/s. Round your answers to four decimal places. a) Find an equation v(t) for the object velocity. v(t) = Preview b) Find the object's displacement (in meters) from time 0 to time 3. Preview meters c) Find the total distance traveled by the object from time 0 to time Preview meters
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.

Which equation represents the equation of the parabola with focus (-3, 3) and directrix y =7?
y =1/8 (x+3)^2- 5 y = 1/8(x -3)^2 + 5 y = -1/8 (x+3)^2 + 5
y=-l/8(x-3)^2 + 5
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.

The events described are non-overlapping The probability of randomly meeting a three-child family with either exactly one or exactly two boy children is_____. ( type an integer or a simplified fraction.)
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

Step-by-step explanation:
(45 points =15′×1+106×3) Maria likes donuts (q1) and coffee (q2). Her utility function is U=10q12q2. The marginal utility for donuts is MU1=20q1q2 and the marginal utility for coffee is MU2=10q12 3.1 Derive the demand function for donuts and the demand function for coffee. You must show all of your work to receive full credit. 3.2 Maria's weekly allowance is $90, which she spends on donuts and coffee only. The price of donuts (p1) is $10, and the price of coffee (p2) is $5. What is her optimal consumption of donuts and coffee? 3.3 Suppose her weekly allowance increases to $120, then it increases to $150. Find the new optimal bundles and on a graph, draw the Income Offer Curve. Using numerical values when possible, label all budget lines intercepts, axes, indifference curves, and optimal bundles. 3.4 Given the three optimal consumption bundles calculated above, illustrate the En gel Curve for donuts. Use numerical values to label the optimal bundles and label the axes. Are donuts normal goods (explain)?
3.1 To derive the demand functions for donuts (q1) and coffee (q2), we need to maximize Maria's utility subject to her budget constraint. The budget constraint is given by p1*q1 + p2*q2 = M, where p1 and p2 are the prices of donuts and coffee, respectively, and M is Maria's weekly allowance.
To maximize utility, we set up the Lagrangian function:
L = U - λ(p1*q1 + p2*q2 - M)
Taking partial derivatives with respect to q1, q2, and λ, we get:
∂L/∂q1 = 20q1*q2 - λp1 = 0
∂L/∂q2 = 10q1^2 - λp2 = 0
∂L/∂λ = p1*q1 + p2*q2 - M = 0
From the first two equations, we can solve for λ:
20q1*q2 / λp1 = 10q1^2 / λp2
2q2 / p1 = q1 / p2
Substituting this into the budget constraint, we have:
p1*q1 + p2*(2q1/p1) = M
p1^2*q1 + 2p2*q1 = p1*M
q1 = p1*M / (p1^2 + 2p2)
Similarly, we can find q2:
q2 = (2q1 / p1) * (p1 / p2)
q2 = 2q1 / p2
Therefore, the demand function for donuts is q1 = p1*M / (p1^2 + 2p2), and the demand function for coffee is q2 = 2q1 / p2.
3.2 Given that p1 = $10, p2 = $5, and Maria's weekly allowance M = $90, we can substitute these values into the demand functions to find the optimal consumption of donuts and coffee:
q1 = (10*90) / (10^2 + 2*5) = 6
q2 = 2q1 / 5 = 2(6) / 5 = 2.4
Therefore, her optimal consumption is 6 donuts and 2.4 cups of coffee.
3.3 If Maria's weekly allowance increases to $120, the new optimal consumption can be calculated using the demand functions:
q1 = (10*120) / (10^2 + 2*5) ≈ 7.2
q2 = 2q1 / 5 = 2(7.2) / 5 ≈ 2.88
Similarly, when her weekly allowance increases to $150:
q1 = (10*150) / (10^2 + 2*5) ≈ 9
q2 = 2q1 / 5 = 2(9) / 5 = 3.6
To draw the Income Offer Curve, we can plot the combinations of q1 and q2 for different levels of Maria's weekly allowance on a graph. The x-axis represents the quantity of donuts (q1), and the y-axis represents the quantity of coffee (q2). We connect the optimal bundles obtained for each level of allowance, creating a curve that represents Maria's choices as her income changes.
3.4 The Engel Curve shows the relationship between income and the quantity demanded of a good while holding prices constant. By using the optimal consumption bundles for different levels of Maria's weekly allowance, we can plot the Engel Curve for

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.

A student analyzed the diagram and incorrectly concluded that AB = 2BC. Explain the student's error.
EB is the perpendicular bisector of AD,
so AB= BD.
angle BEC is congruent to angle DEC, so
BC= CD.
BC + CD = BD = AB, and
BC + CD = BC + BC = 2BC,
so AB= 2BC
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.

if you deposit money in a savings account with an interest rate (apr) of 6.2% and the account compounds monthly, which is your annual percentage yield (apy)? convert your answer to a percent and round it to two decimal places.
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.
