Answer:
a= -1
b= 7
c= 0
Step-by-step explanation:
equation is
y=h(x)(x-7)
let x be 5 and y be 10 to solve for a
10=h(5)(5-7)
10=h(-10)
h=-1
now equation is
y= -x²+7x
so a=-1
b=7
c=0
Answer:
point r (2,-9)
Step-by-step explanation:
You move left one and down 4 from point c
- The centimeter is defined as a unit of lenght. Its symbol is: "cm".
- 1 centimeter=10 milimeters.
- The milimeter is defined as a unit of lenght and its symbol is "mm".
1. If you want to convert 47 milimeters to centimeters by using proportions, you have:
10 mm/1 cm=47mm/x
2. Then, you only have to clear the "x":
(10 mm)x=(47mm)(1 cm)
x=(47 mm)(1 cm)/10 mm
3. Therefore, the result is:
x=4.7 centimeters
Answer:
b = 36
Step-by-step explanation:
Assuming this is a right triangle with hypotenuse = c and legs a and b
Then using Pythagoras' identity.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
a² + b² = c², and substituting values
15² + b² = 39², that is
225 + b² = 1521 ( subtract 225 from both sides )
b² = 1296 ( take the square root of both sides )
b = 
= 36
