Write a quadratic function f whose zeros are 3 and 10
Answer:
[tex]f(x) = {x}^{2} - 13x + 30[/tex]
Step-by-step explanation:
A quadratic equation may be expressed as a product of the two binomials. The roots of the equations are 3 and 10, so the factors are (x-3) and (x-10).
f(x) = (x-3)(x-10)
f(x) = x^2 - 13x + 30

i hope this helps you!
Answer:
The answer is 9.
Step-by-step explanation:
Hey there, so it looks to me that you just have to subsitute 2 in for x, and solve the equation. Like this.
1. Plug in X: 3(2)^2 -2(2) + 1
2. Solve exponents (2)^2 = 4, so the equation is 3(4) - 2(2) + 1
3. Multiplication: 3 × 4 = 12, and -2 × 2 = -4, so the equation is 12 - 4 + 1
4. Addition: -4 + 1 = -3, so it is now 12-3
5. Subtraction: 12-3 = 9, so the answer is 9!
I hope this helps.

Calculate the length of the unknown side of this right-angled triangle.
9 cm
8 cm
Answer:
the length of the unknown side of the right angle triangle is 1 cm
Step-by-step explanation:
The computation of the length of the unknown side of the right angle triangle is shown below:
= √9^2 - √8^2
= √81 - √64
= 9 - 8
= 1 cm
Hence, the length of the unknown side of the right angle triangle is 1 cm

7.22
Answer:
361/50 or 7[tex]\frac{11}{50}[/tex]
Step-by-step explanation:
7.22 = 722/100 = 361/50 = 7 11/50
The number 7.22 can be written using the fraction 722/100 which is equal to 361/50 when reduced to lowest terms.
It is also equal to 7 11/50 when written as a mixed number.
You can use the following approximate value(s) for this number:
7.22 =~ 7 2/9 (if you admit an error of = 0.030779%)
361/50 =~ 7 1/4 (if you admit an error of 0.415513%)
7.22 =~ 7 (if you admit an error of -3.047091%)

Alma is going to walk through the park from Point A to
Point B
What distance will she walk?
HELPPPPPPPPPPPPPPPPP
Answer:
I think the answer is 200 feet
Step-by-step explanation:
Pythagoras is the sum of the square of two sides is equal to the square of the longest side. Then Alma is going to walk through the park from Point A to Point B is 282.84 ft.
What is a right-angle triangle?It is a type of triangle in which one angle is 90 degrees and it follows the Pythagoras theorem and we can use the trigonometry function.
A right-angle triangle has sides with lengths 200 ft and 200 ft.
By Pythagoras theorem, we have
H² = P² + B²
H² = 200² + 200²
H² = 40000 + 40000
H² = 80000
H = 200√2
H = 282.84 ft
Alma is going to walk through the park from Point A to Point B is 282.84 ft.

Draw a line representing the "rise" and a line representing the "run" of the line. State the slope of the line in simplest form.
Answer:
Step-by-step explanation:
First choose two points on the line,
Let the points are A and B.
From point A to B we are moving downwards by (5 - 1 = 4 units)
Therefore, Rise = -4
Horizontal distance between A and B = 2 units
Therefore, Run = 2
Since, slope of a line = [tex]\frac{\text{Rise}}{\text{Run}}[/tex]
Slope = [tex]\frac{-4}{2}[/tex]
= -2
