Easy Math question that I dont get. pleaseeee help.
It is due in 5 minutes
Answer:
First, Third, Fourth, Fifth
Step-by-step explanation:
x² + 2x - 24 = (x + 6)(x - 4) = x² - 4x + 6x - 24 = x² + 2x - 24
True.
x² - 8x + 15 = (x + 5)(x +3) = x² + 3x + 5x + 15 = x² + 8x + 15
False.
3x² + 4x + 1 = (3x + 1)(x + 1) = 3x² + 3x + x + 1 = 3x² + 4x + 1
True.
5x² - 2x - 3 = (5x + 3)(x - 1) = 5x² - 5x + 3x - 3 = 5x² - 2x - 3
True.
4x² - 49 = (2x - 7)(2x + 7) = 4x² + 14x - 14x - 49 = 4x² - 49
True.
First, Third, Fourth, Fifth
Function or not a function?
Answer:
not a function because the points' x-values repeats
Step-by-step explanation:
f(1)= -34
f(n)=f(n−1) - 3
Find an explicit formula for f(n).
Answer:
f(n) = -34 -3(n - 1)
Step-by-step explanation:
The explicit formula for f(n) is given below:
Given that
f(1)= -34
f(n)=f(n−1) - 3
Based on the above information
f(n) = a1 +d(n -1)
a1 = -34
d = -3
So
f(n) = -34 -3(n - 1)
This above represent an explicit formula

find the area of the minor sector
1 r=9cm,tita=70
Answer:
The area is 49.5 cm^2
Step-by-step explanation:
To find the area of the sector, we are going to use the formula for the area of a sector
Mathematically, we have this as;
A = theta/360 * pi * r^2
r = 9 cm and theta = 70
Substituting these values
A = 70/360 * 3.142 * 9^2
A = 49.5 cm^2

cosxcos(x+pi divided by 4)=0
0
Answer:
Step-by-step explanation:
hello : solutions in R
cosxcos((x+π)/4) =0
means : cosx = 0 or cos((x+π)/4) =0
1) cosx = 0 means : x = π/2+kπ k in Z
2) cos((x+π)/4) =0 means : (x+π)/4 = π/2+kπ .......continu calculate : x

Answer:
x = 65
Step-by-step explanation:
Triangle interior angle sum is 180 degrees.
2x + 25 + 25 = 180
2x = 130
x = 65
Answer:
65
Step-by-step explanation:
OK so we know that the bottom line shows a 180 degrees angle
so 180-25+25 = 180-50 = 130
Now divide 130 by 2 and you should get 65.
