Mabye 3,0+10,3 i think because of the coordinates im not sure thougg

Answer:

y=2x+3

Step-by-step explanation:

*Note: I am finding the equation in Slope Intercept form (y=mx+b; m= slope, b= y-int; (x,y)= a coordinate on the plane)

*Note: This is the Slope Intercept from: \frac{y_{1}-y_{2}  }{x_{1}-x_{2}}

1. Find two points on the line: (3,9) and (0,3)

2. Using those points, find the slope (m):

\frac{9-3}{3-0} =\frac{6}{3} = 2

m=2

3. Thankfully, we don't have to find the y-intercept because it is already shown in the graph.

b=3

4. Now plug in the unknowns into the equation:

y=2x+3

5. Enjoy your answer!!!!!!!!!!!!

Help, will give brainlist!!
Licemer1 [7]

Answer:

<u>Fred.</u>

Started hang gliding at a height of 700 ft and descends 15 feet every seconds

<u>Gene</u>

Started hang gliding at a height of 575 ft and descends 10 feet every seconds

Step-by-step explanation:

The function that models Fred's hang gliding is f(x)=-15x+700

The initial value is 700 feet. This Fred was 700 feet above see level before he starts descending.

The rate of descent is -15 ft/s. This means Fred descends 15 feet in one second.

From the table the initial height is 575 ft. This means Gene was 575 feet above sea-level at the beginning of the hang gliding.

The rate of descent is \frac{565-575}{1-0} =-10 ft/s.

This means that in every seconds, Gene descends 10 feet.

The function g(x)=x^2+3. The f(x)=g(x+2)
vekshin1

Answer:

f(x)=x^2+6x+12

Step-by-step explanation:

Given:

The function 'g(x)' is given as:

g(x)=x^2+3

Now, the function 'f(x)' is given as:

f(x)=g(x+2)

So, the function 'f(x)' is a transformation of 'g(x)'.

In order to find f(x), we replace 'x' by (x + 2) in the 'g(x)' function equation. This gives,

g(x+2)=(x+2)^2+3

Using the identity (a+b)^2=a^2+b^2+2ab, we get:

g(x+2)=x^2+3^2+6x+3\\\\g(x+2)=x^2+9+6x+3\\\\g(x+2)=x^2+6x+12

Hence the function f(x) is given as:

f(x)=x^2+6x+12

In right triangle PQR , PQ=12 cm and QR=5cm .What is cos R?
Juliette [100K]

Answer:

cosR = \frac{5}{13}

Step-by-step explanation:

assuming the right triangle has ∠ Q = 90° with legs 5 and 12

then this is a 5- 12- 13 right triangle with hypotenuse PR = 13 cm

then

cosR = \frac{adjacent}{hypotenuse} = \frac{QR}{PR} = \frac{5}{13}
