could somebody help

Answer:

45

Step-by-step explanation:

this person posted the same question twice and I detailed on the other.

Step-by-step explanation:

Discriminant of quadratic equation ( ax² + bx + c = 0 ) could be calculated by using :

D = b² - 4 a c

From the value of Discriminant , we know how many solutions the equation has by condition :

D < 0 → No Real Roots

D = 0 → One Real Root

D > 0 → Two Real Roots

An axis of symmetry of quadratic equation y = ax² + bx + c is :

Let us now tackle the problem!

Given:

f(x) = 3x² - 6x - 13

Asked:

Domain = ?

Solution:

Velocity is a vector quantity.

Vector quantity has magnitude and direction.

Directon of vector is represented by the sign of the quantity

If x is the velocity of the boat relative to land , then:

The value of x could be positive , negative or zero.

Answer:

Anthony is rowing a boat upstream. The following equation models his speed: f(x) = 3x2 − 6x − 13, where x is the velocity of the boat relative to land. What is the domain of the function?

All real numbers

x ≥ 1

x ≤ −6

x ≥ −13

Step-by-step explanation:

it is a

Answer: 2 3/4

Take the reciprocal of the second fraction by flipping the numerator and denominator and changing the operation to multiplication. Then the equation becomes

11/12×3/1=?

By multiplying this, you get 11/4. This simplifies to 2 3/4

Answer:

B

Step-by-step explanation:

Because there parallel

Answer:

Step-by-step explanation:

1(x+y=4)

-1(x-y=7)

x+y=4

-x+y=-7

x-x=4-x

-x=x=-7+x

4-x=-7+x

4-x-x=-7

4-2x=-7

-2x=-7-4

-2x/-2=-11/-2

x=5.5

Answer:

28 and 112

Step-by-step explanation:

4n+n=5n. 5n+40=180 5n-40=140. 140/5= 28. 28* 4=112

Answer: F.

Step-by-step explanation:

First we have to determine the common factor for all of them, which in this case is 11.75. Then we have to multiply that by 40 which gives us 470.

Answer: its different because when you add a negative sign to an answer it is valued less then a answer without the negative sign

Answer:

You use the division property of inequality to isolate the variable for both inequalities. You need to reverse the direction of the inequality symbol when dividing both sides by a negative number.

edge

Answer: 31.18

Step-by-step explanation:

The problem is focused on mainly the right triangle made up of points M, Q, and R.  This problem can be solved with the base formula, b = a · tan(β) where a = the length of line MR, β = m∠MQR, and b is the unknown length of RQ.  

Given:

RQ = 18 · tan(60°)

Point M is the midpoint of line PM and line MR.  Since MP is equal to 18, MR has to be 18 as well.  This means that the value of a is 18.

The vertex of ∠MQR is Q, which is 60°.

Step 1: Find the tangent of 60°

The tangent of 60° is √3

Step 2: Solve

RQ = 18 · √3

18 · √3 = 31.18

RQ is equal to 31.18

Answer:

value of T = 20

Step-by-step explanation:

[tex]2900=250+132.50T\\2900-250=132.50T\\2650=132.50T\\2650/132.50=T\\20=T[/tex]

If this is the whole question so we can say that the value of T is 20 if there is more to the question than it help us tell what T signifies other than that it's just a plain value.

Answer:

she is wrong, offer 2 results in lower interests

Step-by-step explanation:

total amount paid if offer 1 is accepted:

$6,000 x (1 + 3%)² = $6,000 x 1.0609 = $6,365.40

she will pay $365.40 in interests

total amount paid if offer 2 is accepted:

($6,000 x 1.01) x 1.05 = $6,060 x 1.05 = $6,363

she will pay $363 in interests

Compounding interest refers to interest that earns more interest itself, e.g. in the first offer, the $180 of interests charged for the first year will earn $5.40 in extra interests. While offer 2 only charges $60 in interests during the first year which will in turn earn $3 of interests. The difference between both offers is that interest charges in offer 1 earn more interests than the interest in offer 2 = $5.40 - $3 = $2.40

Answer:

Step-by-step explanation:

This is a proportion problem.

760 / 90 = x / 28            Cross multiply

90 * x = 760 * 28            Simplify the right side

90x = 21280                   Divide by 90

x = 21280/90

x = 236.4

Answer:

1/5

Step-by-step explanation:

pick any points, for example (6, -1) and (11, 0)

slope is m= (y2-y1) / (x2-x1) = -1-0 / 6-11 = -1 / -5 = 1/5
