Step-by-step explanation:

the distance between the 2 points is 10

9514 1404 393

Answer:

  a) x = {-1, 3, 4}

  b) (0.472, 13.128)

  c) (3.528, -1.128)

  d) x < 0.472 U x > 3.528

  e) 0.472 < x < 3.528

Step-by-step explanation:

This is a cubic (odd degree) function with a positive leading coefficient, so it will be increasing until the first turning point, and after the last turning point. It will be decreasing between the turning points.

a) A graph shows the zeros to be x = -1, x = 3, x = 4.

b) A graph shows the local maximum to be approximately (0.472, 13.128). The x-coordinate of this point is exactly 2-√(7/3).

c) The local minimum is about (3.528, -1.128). Its x-coordinate is exactly 2+√(7/3).

d) As stated above, the increasing intervals are (-∞, 0.428) ∪ (3.528, ∞).

e) The decreasing interval is (0.428, 3.528).

Additional comments

The sum of odd-degree term coefficients is the same as the sum of coefficients of even-degree terms, so you know one of the roots is -1. Factoring that out gives the quadratic x^2 -7x +12 = (x -3)(x -4), so the other two roots are 3 and 4.

The derivative is 3x^2 -12x +5 = 3(x -2)^2 -7, so its roots (turning points of f(x)) are 2±√(7/3).

I find a graphing calculator can show me the roots and turning points easily.

= 0.005625

Step-by-step explanation:

Subtract: 7/

8

- 4/

5

= 7 · 5/

8 · 5

- 4 · 8/

5 · 8

= 35/

40

- 32/

40

= 35 - 32/

40

= 3/

40

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of the both denominators - LCM(8, 5) = 40. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 8 × 5 = 40. In the next intermediate step the fraction result cannot be further simplified by canceling.

Answer:

a1=12

a6=12

a5=20

a3=20

a4=15

a2=15

as=94

Step-by-step explanation:

it is asking for each of the areas

I'm assuming As stands for areas summed

Answer:

a1=a6=lb=3×4=12

a5=a3=lb=5×3=15

a4=a2=lb=5×4=20

As=12×2+15×2+20×2=a1+a2+a3+a4+a5+a6=24+30+40= 94

Answer:

Step-by-step explanation:

Answer:

First find the rate for a year .

5000 dollars × 6.25 = 31 250

After you find it multiply it by 20 ( because there are 20 years)

31 250 × 20 = 625000

Answer:

Diego had 6,250 in the bank after 20 years.

Step-by-step explanation:

5,000/100=50

50*6.25=312.5*20=6250

Answer:

1) This HAS a right angle

2) This is an obtuse triangle

Step-by-step explanation:

1)

4² + 3² = 5²

16 + 9 = 25

25 = 25 ✅

2)

5² + 6² = 8²

25 + 36 = 64

61 ≠ 64 ❌

Since c is bigger, this is an obtuse triangle

Answer:

x=10

Step-by-step explanation:

Pythagorean Thereom: a^2+b^2 = c^2 when the triangle is right which it is since the 90 degree angle is marked.

a=8 and b=6

8^2+6^2= 64+36 = 100

Take the square root of 100 and get 10.

Step-by-step explanation:

It will be A And C.

Answer:

A Scalene

B Isosceles

C Equilateral

Explanation: Interior angles are all different To see why this is so, imagine two angles are the same. The triangle would then be an Isosceles triangle, which has two sides the same length. Similarly, if all three angles are the same, it would be an equilateral triangle and all three sides would be the same length.

Answer:

Step-by-step explanation:

(x - 2) => x = 2

f(x) = f(2)

= 2x³ - 5x² + 3x + 7

= 2(2)³ - 5(2)² + 3(2) + 7

= 2×8 - 5×4 + 6 + 7

= 16 - 20 + 6 + 7

= 29 - 20

= 9

Answer:

9

Step-by-step explanation:

Assuming that 6.8 means the area of the triangle, the height would be 1.94.
