Answers
Answer:
[tex]2(x - 5) ( 9x - 2)[/tex]
Step-by-step explanation:
((2•3^2x^2) - 94x) + 20
Pull like factors :
18x^2 - 94x + 20 = 2 • (9x^2 - 47x + 10)
Factor
9x^2 - 47x + 10
The first term is, 9x^2 its coefficient is 9.
The middle term is, -47x its coefficient is -47.
The last term, "the constant", is +10
Step-1: Multiply the coefficient of the first term by the constant 9 • 10 = 90
Step-2: Find two factors of 90 whose sum equals the coefficient of the middle term, which is -47.
-90 + -1 = -91
-45 + -2 = -47
Step-3: Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -45 and -2
9x^2 - 45x - 2x - 10
Step-4: Add up the first 2 terms, pulling out like factors :
9x • (x-5)
Add up the last 2 terms, pulling out common factors :
2 • (x-5)
Step-5: Add up the four terms of step 4 :
(9x-2) • (x-5)
Which is the desired factorization
thus the answer is
[tex]2(x - 5) ( 9x - 2)[/tex]
Answer:
Solution given:
18x²-94x+20
taking common
2(9x²-47x+10)
doing middle term factorization
90=45*2
2(9x²-45x-2x+10)
2(9x(x-5)-2(x-5))
2(9x-2)(x-5)
2(x-5)(9x-2)
Last one is a required answer.

Write the equation for a radical function that has been flipped left and shifted down 1.
Answers
Answer:
[tex]g(x)=\sqrt{-x}-1[/tex]
Step-by-step explanation:
Let's use the parent function [tex]f(x)=\sqrt{x}[/tex] as an example
Because we are flipping the radical function left, this means [tex]f(x)=\sqrt{-x}[/tex]
Because we are shifting down 1 unit vertically, we have [tex]g(x)=\sqrt{-x}-1[/tex]
Therefore, the final function is [tex]g(x)=\sqrt{-x}-1[/tex]

Step-by-step explanation:
Answer:
x = 6
Step-by-step explanation:
Use the Intersecting chord theorem;
Rule: (CE) * (EB) = (AE) * (ED)
CE = x
EB = 15
AE = 9
ED = 10
=> (x) (15) = (9) (10)
15x = 90
Now Divide each side with 15
=> x = 6

Step-by-step explanation:
the game ended at 9:10pm
Answer:
21:10 (24-hour clock) or 9:10 ( 12-hour clock)
Step-by-step explanation:
Two ways it can be solved:
Starting time: 7:30
Game lasted- 1 hour and 40 minutes
Ending time-?
7:30 is converted to 24 hrs timing clock:∴ hr I min
7 : 30 pm
+ 12 : 00
___________
= 19 : 30
Then, hr I min
19 : 30
+ 1 : 40
______________
= 20 : 70
+ 1 : - 60
______________
= 21 : 10
So it ended at 21:10 (24-hour clock) or 9:10 ( 12-hour clock).
or you can just add up :hr I min
7 : 30pm
+ 1 : 40
________
= 8 : 70
+ 1 : - 60

Find the area of each semicircle. Round to the nearest tenth. Use 3.14 for Pi. 1. Diameter = 9.4 mm 2. Radius = 3 1/2 ft 3. Radius =8 in
Answers
Answer:
34.68 mm^2
19.23 ft^2
100.48 in^2
Step-by-step explanation:
Area of a circle = 0.5 x nr^2
the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
A radius is half of the diameter
0.5 x (9.4/2)^2 x 3.14 = 34.68
0.5 x (3.5)^2 x 3.14 = 19.23 ft^2
0.5 x (8)^2 x 3.14 = 100.48 in^2
