Answer:
Step-by-step explanation: One of the fundamental identities is #1+cot^2(x) = csc^2(x)#.
Starting with your given:
#cot^2(x)-csc^2(x)#
Replace #csc^2(x)# with #1+cot^2(x)#:
#cot^2(x)-(1+cot^2(x))#
#=cot^2(x)-1-cot^2(x))#
#=-1#

Round your answer to the nearest hundredth.
Answer:
Step-by-step explanation:
Take AC as x
90° + x +70°= 90°
x = 70 + 90 = 160 - 90 = 70
x = 70
Hope this answer will help you!!!!!
Step-by-step explanation:
90°+?+70°=90°(right angle)
?=70+90=160-90=70
?=70

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

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
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

1. what is the equation of a line that has an x-intercept of 2 and a y-intercept of 8
Answer:
B
Step-by-step explanation:
x- intercept = 2 .So, Coordinate(2 , 0)
y-intercept = 8 . So, Coordinate (0, 8)
[tex]Slope = \frac{8-0}{0-2}\\\\=\frac{8}{-2}\\\\=-4[/tex]
Slope y-intercept form: y = mx + b {Here, b is y-intercept}
y = -4x + 8

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.
