Answer:

a = 0.9

Step-by-step explanation:

For the quadratic equation \(\boxed{ax^2 + bx + c = 0}\) to have exactly one real root, the value of its discriminant, \(\boxed{b^2 - 4ac}\), must be zero.

For the given equation:

\(y = ax^2 - 6x + 10\),

• a = a

• b = -6

• c = 10.

Substituting these values into the formula for discriminant, we get:

\((-6)^2 - 4(a)(10) = 0\)

⇒ \(36 - 40a = 0\)

⇒ \(36 = 40a\)

⇒ \(a = \frac{36}{40}\)

⇒ \(a = \bf 0.9\)

Therefore the value of a is 0.9 when the given quadratic has exactly one root.

Answer:

you would make 400 each week

Step-by-step explanation:

The expected number of times for the probability of getting at least one heads after flipping a two coins at the same time is equal to 1/4.

Total number of coins flipped at the same time = 2

Sample Space of coin 1  and coin 2 = { H, T}

Let 'y' represents number of times getting heads

Probability of each outcome head and tail is = 1/2

y      :     0              1                

p(y)  :      1 / 2        1/2            

Expected value of getting heads by flipping each coin

E(Y) = ∑y p(y)

Y₁ and Y₂ are two expected number for each coin to get head

Both coins are independent of each other.

E(Y₁) = 1/2

E(Y₂ ) = 1/2

E(Y₁ × Y₂)

= E(Y₁)  × E(Y₂ )

= ( 1/2) ( 1/2)

= 1/4

Therefore, the expected number of times for the probability of getting at least one head is equal to 1/4.

Step-by-step explanation:

the slope does not change in y at all.

The implied domain of f⁻¹(x) is the implied range of f(x), and the implied range of f⁻¹(x) is the implied domain of f(x).

State the Implied Domain and Range of each of the following functions. If f⁻¹(x). exis'(x).

(i) f(x) = √5-3x

(ii) f(x) = √4-x²

(iii) f(x) = 2 + In (3x-1).

(i) The implied domain of f(x) = √5-3x is the set of all real numbers x such that 5-3x ≥ 0, since the square root of a negative number is undefined in the real numbers. Solving for x, we get x ≤ 5/3. Therefore, the implied domain of f(x) is (-∞, 5/3].

To find the implied range of f(x), note that the square root function always returns a non-negative value. Therefore, the smallest value of f(x) is 0, which is achieved when x = 5/3. As x decreases, f(x) increases without bound. Therefore, the implied range of f(x) is [0, ∞).

(ii) The implied domain of f(x) = √4-x² is the set of all real numbers x such that -2 ≤ x ≤ 2, since the square root of a negative number is undefined in the real numbers. Therefore, the implied domain of f(x) is [-2, 2].

To find the implied range of f(x), note that f(x) represents the y-coordinate of a point on the upper half of the unit circle with radius 2 centered at the origin. Therefore, the implied range of f(x) is [0, 2].

(iii) The implied domain of f(x) = 2 + In(3x-1) is the set of all real numbers x such that 3x-1 > 0, since the natural logarithm function is undefined for non-positive arguments. Solving for x, we get x > 1/3. Therefore, the implied domain of f(x) is (1/3, ∞).

To find the implied range of f(x), note that the natural logarithm function returns all real numbers as outputs. Therefore, as x increases without bound, f(x) increases without bound. Therefore, the implied range of f(x) is (-∞, ∞).

If f⁻¹(x) exists, then the implied domain and range of f(x) are swapped for f⁻¹(x). In other words, the implied domain of f⁻¹(x) is the implied range of f(x), and the implied range of f⁻¹(x) is the implied domain of f(x). However, the inverse function f⁻¹(x) does not necessarily exist for every function.

A conditional statement is an if-then statement in which p is a hypothesis and q is a conclusion.

a)

In this case the hypothesis is: It is monday

The conclusion is: the museum is closed.

Then the conditional statement for the hours of the musuem on mondays is:

If it is monday then the museum is closed.

b)

In this case the hypothesis is: it is thursday

the conclusion is: the museum opens from 10 am to 8 pm.

Then the conditional is:

If it is thursday then the museum opens from 10 am to 8 pm.

c)

To find the converse statement we need to interchange the hypothesis and the conclusion, therefore the converse of b is:

If the museum opens from 10 am to 8 pm then it is thursday.

Since the museum opens in the same hours on tuesday, then this statement is false.

To find the inverse statement we need to negate the hypothesis and conclusion, therefore the inverse of b is:

If it is not thursday then the museum does not open from 10 am to 8pm.

Since the museum opens in this hours on tuesday, then this statement is false.

To find the contrapositive statement we need to interchange the hypothesis and the conclusion of the inverse statement, then the contrapositive of b is:

If the museum does not open from 10 am to 8 pm then it is not thursday.

Since we the museum only opens in this hours two days of the week and one of them is thursday, then this statement is true.

d)

A biconditional statement is a combination of a conditional statement and its converse written in the if and only if form.

With this is mind a true biconditional is a statement in whose conditional and its converse are true.

The statement in part b can't be written as a true biconditional, since the converse is false.

The statement in part a can be express as a biconditional because its converse is true. Then:

The length of ET and the length of RT to the nearest tenth will be 268.3 units and 198.7 units, respectively.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

RECT is a square (not drawn to scale).

RA = 13² - 3x - 3  

AC = x(x + 2)

The diagonals of the square will be RC and ET. And "A" is the intersection point. Then the equation is given as,

RA = AC

13² - 3x - 3 = x(x + 2)

169 - 3x - 3 = x² + 2x

x² + 5x - 166 = 0

x = [- 5 ± √(5² - 4 × 1 × (-166))] / (2 × 1)

x = 10.62, -15.62

Then the length of AC is given as,

AC = 10.62 (10.62 + 2)

AC = 134.13 units

The diagonals of the square are congruent. Then we have

ET = RC

ET = 2 AC

ET = 2 x 134.13

ET = 268.3 units

Then the length RT is given as,

RT = ET / √2

RT = 198.7 units

The length of ET and the length of RT to the nearest tenth will be 268.3 units and 198.7 units, respectively.
