HELPP!!! BRAINLYESTTTTT!!!!!! GRAPH THE FUNCTION:

Mathematics
1 answer:
Roman55 [17]3 years ago
5 0

Answer:


Step-by-step explanation:

We are given the function f(x) = -3/4(x) +6.

We know that the slope intercept form of a line is y = mx + b

Here, the slope m = -3/4.

The y-coordinate of the y intercept is b = 6 so the y-intercept is at the point (0,6) [x is always 0 at the y-intercept]

If you have to points you can graph the line, we only have the point (0,6).

To find the second point we use the slope.

We add the bottom point of the slope to the x coordinate of the y-intercept and we add the top part of the slope to the y coordinate of the y-intercept, so our second point is (0 + 4, 6 +(-3)) = (4, 3).

You then plot the points we have: (0,6) and (4,3) and draw the line through them.

If p(x)= 2x3+ a x2+ 3x–3 and f(x) = x3 + x2-4x+ aleave the same remainder when divided by x-2, find the value of a.
Luda [366]

Answer:

a = 3

Step-by-step explanation:

p(x) = 2x^{3} + ax^{2} +3x -3\\f(x) = x^{3} + x^{2} - 4x + a

To get the remainder when these polynomials are divided by x - 2, subsitute(x = 2) into both functions.

p(2) = 2(2^{3}) + a(2^{2}) +(3*2) -3\\p(2) = 19 - 4a\\f(2) = 2^{3} + 2^{2} - (4*2) + a\\f(2) = 4 + a

Since the remainders are the same, p(2) = f(2)

19 - 4a = 4 + a

19 - 4 = a + 4a

15 = 5a

a = 15/5

a = 3

What is h(x)=|3x|-1 ? x=7. Insert 7 for x. Thanks!!
tiny-mole [99]

Answer: 20

<u>Step-by-step explanation:</u>

h(x) = |3x| - 1

h(7) = |3(7)| - 1

      = |21| - 1

      =  21  - 1

Calculate the slant height for the given cone.Round to the nearest tenth. Diameter =8cm
Karo-lina-s [1.5K]

Answer:

1) The slant height = 9.8 cm ⇒ (C)

2) The slant height = 11.4 cm ⇒ (D)

Step-by-step explanation:

1) ∵ The slant height of the cone = √[(radius)² + (height)²]

∵ Diameter = 8 cm

∴ Radius = 4 cm

∵ Height = 9 cm

∴ Slant height = √(4² + 9²) = √97 = 9.8 cm ⇒ (C)

2) ∵ The slant height of the cone = √[(radius)² + (height)²]

∵ Diameter = 18 cm

∴ Radius = 9 cm

∵ Height = 7 cm

∴ Slant height = √(9² + 7²) = √130 = 11.4 cm ⇒ (D)
