Step-by-step explanation:
Simplify the expressions.
Over which interval is the graph of y= cos(x) strictly increasing?
A. 0 B. 0 C.pi/2D. Pi< x <2pi
Answer:
D. [tex]\pi<x<2\pi[/tex]
Step-by-step explanation:
Given the function
[tex]y=cosx[/tex]
Kindly refer to the graph attached in the answer area.
Referring to the intervals [0, [tex]2\pi[/tex]].
It decreases from the interval [0, [tex]\pi[/tex]] and then starts increasing in the interval
[tex][\pi,2\pi][/tex].
Proving by taking derivative:
Taking derivative of the function, [tex]y=cosx[/tex]
[tex]\dfrac{dy}{dx}=-sinx[/tex]
In the interval [tex][\pi,2\pi][/tex], [tex]sinx[/tex] is negative i.e. [tex]sinx<0[/tex].
Therefore [tex]-sinx>0[/tex]
When, the derivative of a function is positive, then the function is strictly increasing.
So, the answer is:
D. [tex]\pi<x<2\pi[/tex]

If f(x) = 2x -1, what does f(10) equal?
-1
16
19
33
Asap pls
Step-by-step explanation:
f(x) = 2x - 1
f(10) = 2(10) - 1
= 20 - 1 = 19
A Segment Has A Midpoint At (3,2)And One Endpoint At (4,-4) What Is The Ordered Pair Of The Other Endpoint ?
Answer:
Step-by-step explanation:
(x + 4)/2= 3
x + 4 = 6
x = 2
(y - 4)/2= 2
y - 4 = 4
y = 8
(2, 8) the other endpoint
FInd the slope y = -2
Answer:
The slope is ZERO. It has no slope

5. What is the side length of a square with
an area of 7 square units?
Answer:
3.5 units
Step-by-step explanation:
Since it's a square, all sides are the same length. To find the two side lengths used to get the area, you divide 7 by 2.
7÷2=3.5 units
solve for T
10t = -50
Answer: t=-5
Step-by-step explanation:
if 10t=-50, you have to solve for the equation. to solve, you have to get the variable by itself. to get the variable by itself, you have to divide both sides by 10. 10t/10=-50/10. t=-5
f(x) = -2x + 10
f(-1.5)
a 13
b -13
c 20
d -20
Answer:
f( -1.5) = 13
Step-by-step explanation:
F(-1.5)= -2(-1.5)+10
-2 times -1.5 = 3
3+10
f( -1.5) = 13
what can you conclude about parallel lines with regard to the distance between them? use the word perpendicular your answer.
Answer: Hope this helps ;3
The shortest distance between two parallel lines is the length of the perpendicular segment between them. It doesn't matter which perpendicular line you choose, as long as the two points are on the lines.
Answer: Perpendicular is the length of the distance of parallel lines

Solve: 4(x-1)-3(3x-2)=12(x+2)
Answer:
4x - 4 -9x + 6 = 12x + 24
arrange like terms
-5x +2 = 12x + 24
or, -17x = 22
x = - 22/17
Answer:
4x-4-9x+6=12x+24
4x-12x-9x= 4-6+24
-17 x= 22
X= -22/17

E varies directly with G. When G is 6, E is 10. Find the value of G when E is 18.
Answer:
10.8
Step-by-step explanation:
E has increased by a factor of 18/10 = 1.8, so G will increase by that factor. The corresponding value of G is ...
6 × 1.8 = 10.8 = G
__
If you like, you can write an equation relating G to E:
E = kG
10 = k(6)
k = 10/6 = 5/3
Now for E = 18, we have ...
18 = (5/3)G
18(3/5) = G = 10.8
