28. What is the maximum number of real roots

1 answer:

6 0

The maximum number of real roots is 5 because the degree is 5. The fundamental theorem of algebra states that the degree of a polynomial is the number of real solutions. (The degree is the highest exponent of the polynomial)

Which statement is not used to prove that ΔABC is similar to ΔADE? triangles ABC and ADE in which point E is between points A an

Levart [38]

Answer:

The correct option is;

The sum of angles A and B are supplementary to angle C

Step-by-step explanation:

The statements are analysed as follows

1. Angle A is congruent to itself reflective property

Which shows that ΔABC and ΔADE have a common and equal angle

2. Segment ED and CB are parallel

From the transversal line passing EB and CB which shows that the angles ∠ADE and ∠ABC are equal and also ∠AED and ∠ACB are equal

The statement is used to prove similarity between the ΔABC and ΔADE

3. The sum of angles A and B are supplementary to angle C

The above statements relates to only ΔABC and i does not show similarity between ΔABC and ΔADE.

leonid [27]

Answer:

15 and 9/10 or 15.9

Step-by-step explanation:

4_2/5 + 3_3/10 = 4_4/10 + 3_3/10 = 7_7/10

8_1/5 = 8_2/10

8_2/10 + 7_7/10 = 15 9/10

or 15.9

Which function is the inverse of f(x)= x^3-6x^2+12x-8

Anna71 [15]

We're not given the choices but we don't need them.

The only way this problem is tractable to a middle or high schooler is if the polynomial is perfect cube; a little thought yields

$f(x) = (x-2)^3$

To find the inverse let's call f(x) x and call x y and solve for y.

$x = (y-2)^3$

$y-2 = \sqrt[3]{x}$

$y = 2 + \sqrt[3]{x}$

Problem Page At the city museum, child admission is $6.00 and adult admission is $9.80 . On Wednesday, 151 tickets were sold for

wariber [46]

Answer:

The number of child tickets was 94

Step-by-step explanation:

Let

x-----> the number of child tickets

y----> the number of adult tickets

we know that

$x+y=151$ -----> equation A

$6x+9.80y=1,122.60$ -----> equation B

Solving by graphing

The solution of the system of equations is the intersection point both graphs

The intersection point is (94,57)

see the attached figure

therefore

The number of child tickets was 94

The number of adult tickets was 57
