Answer:

f(x) = 5x^2−7x−10

Step-by-step explanation:

Quadratic equation standard form is f(x) = ax^2 +bx + c . All you had to do was add 3 to both sides of the equation to change this into standard form. :)

Answer:

The number of feet away from the sprinkler where it could spread water would be the radius of the circle in which it is spraying.

The Area of a circle is

πr2=808.64

(3.14)r2=808.64

Divide both sides by 3.14

r2=257.5286624

Square root both sides to get radius

r=16 feet

7 feet away from the sprinkler can it spread water if the area formed by the watering pattern is 907.46 square​ feet

What information do we have?

Area of watering pattern = 907.46 square​ feet

Area of watering pattern = Area of circle

Area of watering pattern = πr²

907.46 = (3.14)r²

r² = 289

r = 17

Length = 17 feet

Answer:

(2,1)

Step-by-step explanation:

The coordinate point between two points divided between ratio a and b is expressed as;

(X, Y) = [(ax1+bx2/a+b,ay1+by2/a+b]

Given the coordinate points (-7,-5) and (5,3) divided within the ratio 1:3

X = ax1+bx2/a+b

X = 1(-7)+3(5)/1+3

X = -7+15/4

X = 8/4

X = 3

Similarly

Y = ay1+by2/a+b

Y = 1(-5)+3(3)/1+3

Y = -5+9/4

Y = 4/4

Y = 1

Hence the required coordinate point is (2,1)

Answer:

$13.76

Step-by-step explanation:

Cost at store A = $29.35

Cost at store B = $32.79

Difference in price at both stores :

Difference = store B - store A

Difference in price = $32.79 - $29.35 = $3.44

Extra cost to f purchasing 4 video games at store B:

Difference in price * number of video games

$3.44 * 4 = $13.76

Answer: 13cm

Step-by-step explanation:

Since rotation and reflection have nothing to do with the size of a triangle the perimeter will stay the same

1.999… is exactly the number 2.

Let x = 1.999… . Then 1000x = 1999.999… . Subtract x from this to eliminate the fractional part, and you get

1000x - x = 1999.999… - 1.999…

1000x - x = 1999 - 1

999x = 1998

x = 1998/999 = 2/1 = 2

So p = 2 and q = 1.

Answer:

2010.62

Step-by-step explanation:

the formula to find a cylinders volume is r and h so you just divide 14 and get 8, then you get the 10 and you solve for how you would usually get your cylinder volume. which is  V=πr2h=π·82·10≈2010.62

Answer:

V=1539.38

Step-by-step explanation:

V=πr2h=π·7^2·10≈1539.3804

or if you just want shortened version

V=π·7^2·10≈1539.3804
