Answer:
no, he is not
Step-by-step explanation:
(-3)^3 is equal to -27, not 27
(-3) (-3) = 9
9 (-3) = -27
Step-by-step explanation:
he is not correct
because (–3)^3=‒3*‒3*‒3=‒27
the correct answer must be 27=3*3*3or (3)^3

Find the Value
A.
B.
C.
D.
Answer:
C
Step-by-step explanation:
Using the trig. identity
sin²x + cos²x = 1 ⇒ cosx = ± [tex]\sqrt{1-sin^2x}[/tex]
Here sinθ = [tex]\frac{1}{2}[/tex] , thus
cosθ = ± [tex]\sqrt{1-(\frac{1}{2})^2 }[/tex] = ± [tex]\sqrt{1-\frac{1}{4} }[/tex] = ± [tex]\sqrt{\frac{3}{4} }[/tex] = ± [tex]\frac{\sqrt{3} }{2}[/tex]
Since 0 ≤ θ > 90 then cosθ > 0 , thus
cosθ = [tex]\frac{\sqrt{3} }{2}[/tex] → C

Shifting into first gear generally increases the engine speed (rpm) while decreasing the
tractor speed (mph). What would be the effect of this change?
A. Both area rate and flow rate would increase.
B. Area rate would increase, and flow rate would decrease.
C. Area rate would decrease, and flow rate would increase.
D. Both area rate and flow rate would decrease.
The effect of this change should be option D. Both area rate and flow rate would decrease.
Information regarding speed:In the case when the first gear is shifted so it increased the engine speed. While on the other hand, it reduced the tractor speed. Due to this, the area rate and the flow rate should be decreased.Learn more about the speed here: https://brainly.com/question/24772838

Solve the two steps equations below and check your solution R/2-8=16
Answer:
r= 48
Step-by-step explanation
r/2 - 8 = 16
+8 +8
r/2 = 24
multiply both sides by two so it cancels out and you get r by itself.
the 2 cancels out and 24 times 2 = 48
r= 48
Which is the solution to the following system x+2y+z=9
X-y+3z=13
2z=10
Step-by-step explanation:
I'm not sure but,here you go
2z = 10
z = 10 ÷ 2 = 5
x + 2y + z = 9
x + y + 3z = 13
____________
x + 2y + 5 = 9
x + y + 3(5) = 13
_____________
x + 2y = 9 - 5
x + y = 13 - 15
___________
x + 2y = 4
x + y = -2 (×-1)
___________
x + 2y = 4
-x - y = 2
___________
y = 6
x = -2y - z + 9 = -2(6) - 5 + 9 = -12 - 5 + 9 = -8
If you wanna check,
x + y +3z = 13
(-8) + 6 + 3(5) = 13
x = -8 , y = 6 , z = 5
I'm not very sure but here you go,I might be wrong^^

The graph that is made up of two straight lines, which has an absolute maximum or absolute minimum, and is symmetric belongs to the
function family.
Answer:
This may be a function of the absolte value family.
f(x) = IxI.
f(x) = x if x ≥ 0
f(x) = -x if x ≤ 0
Where this is the parent function, and the graph is shown below in green.
If the coefficient is positive, then the lines open upwards, and we will have a minimum (in this case, when x = 0).
And also in this case, we have symmetry around the value x = 0.
Now, the vertex can also be an absolute maximum if the coefficient is negative, like in the example shown below in color blue (the equation for the blue graph is f(x) = -3*IxI )

What is the x-intercept of the graph?
A. -4
B. -3/2
C.2/3
D.6
Answer:
A. -4
Step-by-step explanation:
For solving for x intercepts analytically. You can set the the y in the equation to 0. So, 2x-3(0)=12, and solving for x will get you -4.
You can also solve graphically by plugging in the equation and looking at where it intercepts the x axis.
