f(x)=x^2−10x+21 in factored form
Answer:
(x-7)(x-3)
Step-by-step explanation:
The factored form of f(x)=x^2-10x+21 is (x-7)(x-3). In order to find the factored form, you have to find what values add to -10, yet multiply to 21. So, the values that add to -10 and multiply to 21 are -7 and -3. x and x multiply to x^2.
In conclusion, the factored form of f(x)=x^2-10x+21 is (x-7)(x-3).
2. Currently, Yamir is twice as old as Pato. In three years, the sum of their ages will be 30. If Pato's current age
is represented by a, which of the following equations could be used to correctly solve for a?
(1) a + 2a + 3 = 30
.(2) a + 2a +6 = 30
(3) (a +3)+2(a +3) = 30
(4) a +2(a +6)= 30
Given:
Yamir is twice as old as Pato.
In three years, the sum of their ages will be 30.
Pato's current age is represented by [tex]a[/tex].
To find:
The equation that could be used to correctly solve for [tex]a[/tex].
Solution:
We know that, Pato's current age is represented by a, then
Yamir's age = [tex]2a[/tex]
After three years,
Pato's age = [tex]a+3[/tex]
Yamir's age = [tex]2a+3[/tex]
In three years, the sum of their ages will be 30.
[tex](a+3)+(2a+3)=30[/tex]
[tex](a+2a)+(3+3)=30[/tex]
[tex]a+2a+6=30[/tex]
Therefore, the correct option is 2.

Henry was thinking of a number. Henry adds 9.2 to the number, then doubles the result to get
an answer of 12.5. Form an equation with x from the information.
Answer:
2(9.2+x)=12.5
Step-by-step explanation:
Henry is adding 9.2 to your number, x, and after he adds it, he doubles it. This will then allow him to get the answer 12.5

Step-by-step explanation:
The hypotenuse of a right triangle is 10 inches long. The longer leg is 2 inches longer than the shorter leg. Find the side lengths of the triangle.
Answer: Shorter leg = 6 inches
Longer leg = 6+2 = 8 inches
Step-by-step explanation:
Let the shorter leg bw represented by x.
Therefore, the longer leg will be x+2.
The hypothenuse is 10inches
We should note that in Pythagoras theorem, the square of the longer and shorter side equals the square of the hypothenuse. This will be:
x² + (x+2)² = 10²
x² + x² + 4x + 4 = 100
2x² + 4x = 100 - 4
2x² + 4x = 96
2x² + 4x - 96 = 0
x² + 2x - 48 = 0
x² + 8x - 6x - 48 = 0
x(x + 8) -6(x + 8) = 0
x - 6 = 0
x = 0+6.
x = 6
Shorter leg = 6 inches
Longer leg = 6+2 = 8 inches

A ball is thrown into the air with an upward velocity of 28ft/s. Its height h in feet after t seconds is given by the function h = -16t^2 + 28t + 8
Answer:
In bold below.
Step-by-step explanation:
Find derivative which gives the velocity:
V = h' = -32t + 28
At maxm height V = 0 so
-32t + 28 = 0
Time to reach maxm height t = -28/-32 = 0.875 seconds.
So maxm height
= -16(0.875)^2 + 28*0.875 + 8
= 20.25 ft.

Answer:
see explanation
Step-by-step explanation:
The zeros of the graph are x = - 4 and x = 2 , then the factors are
(x + 4)(x - 2) and
y = a(x + 4)(x - 2) ← a is a multiplier
To find a use any other point on the graph and substitute into the equation
Using (0, - 8 ) , then
- 8 = a(4)(- 2) = - 8a ( divide both sides by - 8 )
1 = a
y = (x + 4)(x - 2) = x² + 2x - 8
with b = 2 and c = - 8

The range is:
(PLS Copy and Paste this whole thing in your answer and write the answers)
Answer:
the mean is:48
the median is:35 and 66
the mode is:50
the range is:51
Step-by-step explanation:
the mean =(49+50+45+23+35+ 66+34+74+54+50) over 10 which is equal to 480 over 10 and the answer is 48
the median =the two nunber in the middle since the numbers are even
the mode is the number that repeat it self and 50 repeated 2 time
the range=74-23=51
