Answer:

im assuming slope : 5/4 is slope

Step-by-step explanation:

the formula (y₂ - y₁) / (x₂ - x₁) is how you get slope. plug stuff in and you get (9 - 4) / (8 - 4) and thats 5/4

Factor completely<br> m^2 — Зm — 18
lilavasa [31]

Answer:

(m + 3) (m - 6)

Step-by-step explanation:

Simplify the following:

m^2 - 3 m - 18

The factors of -18 that sum to -3 are 3 and -6. So, m^2 - 3 m - 18 = (m + 3) (m - 6):

Answer: |

| (m + 3) (m - 6)

Point R is located at (1, 2) on a coordinate grid. Point S is located at (4, 5) on the same
Aleksandr-060686 [28]

Answer:

4.2 units

most likely answer choice B

Step-by-step explanation:

(1, 2) and (4, 5)

To find the distance between two points, we use the distance formula:

d = \sqrt{(x_{2}-x_1)^2 + (y_2-y_1)^2 }

Let's plug in what we know.

d = \sqrt{(4 - 1)^2 + (5 - 2)^2 }

Evaluate the parentheses.

d = \sqrt{(3)^2 + (3)^2 }

Evaluate the exponents.

d = \sqrt{(9) + (9) }

Add.

d=\sqrt{18}

Evaluate the radical.

d = 4.24

Round to the nearest tenth.

d = 4.2 units

*note: The answer choice is 4.6. I'm not sure if that is a typo on someone's end, but the distance between these two points is exactly 4.24264068712 units.

Hope this helps!

You are watering a garden. The height h (in feet) of water spraying from the garden hose can be modeled by h(x)=−0.1x2+0.7x+3, w
swat32

Answer:

g(x) = -0.1x^2 + 0.5x + 3.6

Step-by-step explanation:

Given

h(x) = -0.1x^2 + 0.7x  + 3

Required

Determine the new function

From the question, we understand that the new function wants the water to hit the ground 1 ft farther.

1 ft farther implies x + 1

So, in the given function, we substitute x + 1 for x in h(x) = -0.1x^2 + 0.7x  + 3

This gives:

h(x + 1) = -0.1(x + 1)^2 + 0.7(x + 1)  + 3

Expand Bracket

h(x + 1) = -0.1(x + 1)(x + 1) + 0.7(x + 1)  + 3

h(x + 1) = -0.1(x^2+2x+1) + 0.7(x + 1)  + 3

h(x + 1) = -0.1x^2-0.2x-0.1 + 0.7x + 0.7  + 3

Collect Like Terms

h(x + 1) = -0.1x^2-0.2x + 0.7x + 0.7  + 3-0.1

h(x + 1) = -0.1x^2 + 0.5x + 3.6

Hence, the new function is:

g(x) = h(x + 1) = -0.1x^2 + 0.5x + 3.6

g(x) = -0.1x^2 + 0.5x + 3.6
