m= 0 passes through the point (-1,3)
Answer:
y = 3
Step-by-step explanation:
I will assume you want to put this in slope intercept form.
We need to solve for b in y = mx + b since we are given a point and the slope.
y = 0x + b
y = b
3 = b
y = 3
Note that since the slope is 0, there will be nothing to represent m.
Best of Luck!

QUESTION 3 Let V be a vector space and let u, v € V. If W = {au + Bula,8 € R}. prove that W is a subspace of V. [6 marks]
To prove that W = {au + Bula,8 € R} is a subspace of vector space V, we need to show that W satisfies the three conditions for being a subspace: closure under addition, closure under scalar multiplication, and contains the zero vector.
Closure under addition: Let x, y be arbitrary vectors in W. We can write x = au + Bula and y = cu + Cvla, where a, b, c, d are scalars. Now, let's consider the sum of x and y: x + y = (au + Bula) + (cu + Cvla).
By applying the distributive property, we can simplify this to
(a + c)u + (b + d)ula. Since (a + c) and (b + d) are scalars, we see that x + y is also in the form of au + Bula, which means it belongs to W. Therefore, W is closed under addition.
Closure under scalar multiplication: Let x be an arbitrary vector in W and k be a scalar. We have x = au + Bula. Now, let's consider the scalar multiple of x: kx = k(au + Bula). Applying the distributive property, we get kx = (ka)u + (kbl)a. Since (ka) and (kbl) are scalars, we can see that kx is also in the form of au + Bula, indicating that it belongs to W. Thus, W is closed under scalar multiplication.
Contains the zero vector: The zero vector can be expressed as 0 = 0u + 0ula. Since 0 and 0 are scalars, we can see that the zero vector is in the form of au + Bula and therefore belongs to W.
Since W satisfies all three conditions for being a subspace, we can conclude that W is a subspace of V.

Rewrite the definition of the term as a biconditional statement. Two angles are vertical angles when their sides form two pairs of opposite rays. If an angle is vertical to another angle, then the angles do not form pairs of opposite rays. If two angles are vertical, then their sides form two pairs of opposite rays. An angle is vertical to another angle if and only if the angles do not form pairs of opposite rays. Two angles are vertical angles if and only if their sides form two pairs of opposite rays.
Answer:
D. Two angles are vertical angles if and only if their sides form two pairs of opposite rays
Step-by-step explanation:
A conditional statement is a statement that is is not truely ascertain except a particular condition is also true. This is done by using an IF statement. When a statement is biconditional, it means it is combined form of a conditional statement. The later is written by combining "two ifs" i.e IF and only IF. The statement is trying to ascertain two conditional statements at a time.
Given the statement "Two angles are vertical angles when their sides form two pairs of opposite rays.", we can see that it is made up to two statements.
1) Two angles are vertical angles
2) their sides form two pairs of opposite rays.
To ascertain the truthfulness of both statements, we will use the biconditional statement " if and only if". Hence the statement will become "Two angles are vertical angles if and only if their sides form two pairs of opposite rays"
Hence, option D is correct
Harper went into a movie theater and bought 10 bags of popcorn and 6 drinks, costing a total of $79. Damian went into the same movie theater and bought 3 bags of popcorn and 5 drinks, costing a total of $36.50
Answer:
The price of the drink is: $4
and the bag of popcorn costed $5.5
Step-by-step explanation:
Let b=the price of each bag of popcorn
Let d=the price of each drink
One bag of popcorn costs $b, so 10 bags of popcorn cost 10b. One drink costs $d, so 6 drinks cost 6d. The total cost 10b+6d equals \$79:
10b+6d=79
Likewise, if 3 bags of popcorn and 5 drinks cost $36.50, then:
3b+5d=36.50
Write System of Equations:
10b+6d=79

What is the term for a ratio of equivalent measurements that can be used to change a value from one unit into another?
Answer:
conversion factor
Step-by-step explanation:
For each of the following, graph isoquants that produce exactly 10 goods and 25 goods. Be sure to label a couple points in each case. a) f(K, L) = 1/2 min{K, L} b) f(K, L) = 5K^1/2 L^1/2 c) f(K, L) = 1/2K + 1/3L
Isoquants for f(K, L) = 1/2 min{K, L} that produce exactly 10 goods and 25 goods can be graphed, with labeled points.
For function f(K, L) = 1/2 min{K, L}, we can graph the isoquants that represent the combinations of capital (K) and labor (L) that produce exactly 10 goods and 25 goods.
An isoquant represents all the combinations of inputs (K and L) that yield the same level of output. In this case, the isoquants will be curves that connect different combinations of K and L, where the output is constant at either 10 goods or 25 goods.
To graph the isoquant for 10 goods, we plot points where f(K, L) = 10. For example, if we let K = 4 and L = 4, the minimum of K and L is 4, so f(K, L) = 1/2 * 4 = 2 goods.
Since this is less than 10, we need to increase either K or L. We can try K = 8 and L = 4, where the minimum of K and L is still 4, and f(K, L) = 1/2 * 4 = 2 goods. Again, this is less than 10, so we increase K or L further.
Continuing this process, we can plot a few more points and connect them to obtain the isoquant for 10 goods.
Similarly, we can graph the isoquant for 25 goods by plotting points where f(K, L) = 25. For each point, we determine the minimum of K and L, multiply it by 1/2, and check if the result is equal to 25. By plotting and connecting several such points, we obtain the isoquant for 25 goods.

The answer is positive one or '1'
Step-by-step explanation:
Suppose that θ^1 and θ^2 are unbiased point estimators for an unknown population parameter θ such that Var(θ^1)=σ12 and Var(θ^2)=σ22. (a) (2 pts) What are the values of E(θ^1) and E(θ^2) ? Why? (b) (2 pts) Define a new estimator θ^3=aθ^1+(1−a)θ^2 for constant 0
The new estimator θ^3 is also an unbiased estimator with an expectation equal to θ.
(a) The values of E(θ^1) and E(θ^2) are unknown without further information. Being unbiased estimators means that, on average, they provide estimates that are equal to the true population parameter θ. Therefore, we have:
E(θ^1) = θ
E(θ^2) = θ
(b) To find the expectation E(θ^3), we can use the linearity property of expectations:
E(θ^3) = E(aθ^1 + (1 - a)θ^2)
Since θ^1 and θ^2 are unbiased estimators, their expectations are equal to θ:
E(θ^3) = E(aθ^1 + (1 - a)θ^2) = aE(θ^1) + (1 - a)E(θ^2)
Using the values from part (a), we have:
E(θ^3) = aθ + (1 - a)θ = θ(a + 1 - a) = θ
Therefore, the new estimator θ^3 is also an unbiased estimator with an expectation equal to θ.

2. Ana pide un préstamo de $180000 al banco,
desea pagarlo en 12 cuotas mensuales iguales.
El banco utiliza la siguiente expresión para
calcular los intereses: (interés anual)
IA = 180000x200
¿Cuánto debe pagar Ana solo por concepto de
interés en cada cuota, donde el interés a pagar
en cada cuota es el mismo?
Ana must pay $5,400,000 in interest for each monthly installment.
How much must she pay?To calculate the interest payment for each monthly installment, we first need to determine the annual interest rate (IA) and then divide it by the number of months (12) to obtain the monthly interest rate.
Given:
Loan amount (principal) = $180,000Annual interest rate = IA = 1.80000 * 200To find the monthly interest rate, we divide the annual interest rate by 12:
Monthly interest rate = IA / 12
Let's calculate the monthly interest rate:
IA = 1.80000 * 200 = 360,000
Monthly interest rate = 360,000 / 12 = 30,000
Therefore, the monthly interest rate is $30,000.
Now, to calculate the interest payment for each monthly installment, we multiply the monthly interest rate by the loan amount:
Interest payment per installment = Monthly interest rate * Loan amount
Interest payment per installment = $30,000 * $180,000
Calculating this gives us:
Interest payment per installment = $5,400,000
