Answer:
Step-by-step explanation:
-9x^3(x^2 - 4x - 21) =
-9x(x - 7)(x + 3) <===
Answer:
Yes
Step-by-step explanation:
y is the litters of water in the tank
x is the time in minutes
m is the change in litters
b is the initial amount of water
so the formula is y = mx + b
whereas m is -14 and b is 770
y = -14x + 770 or y = 770 - 14x
y = 1.4x - 4.8
the equation of a line in ' slope - intercept form ' is
y = mx + c ( m is the slope and c the y- intercept )
the partial equation is y = 1.4x + c
to find c, substitute (2, - 2) into the partial equation
- 2 = 2.8 + c ⇒ c = - 2 - 2.8 = - 4.8
y = 1.4x - 4.8 is the equation in slope- intercept form
Answer:
117
Step-by-step explanation:
Okay, the problem is asking that we find the hypotenuse of this triangle (AKA, the lake.)
a²+b²=c²
A= 75
B= 90
C is always the hypotenuse.
75²+90²= c²
5,625+8,100= 13,725
√13,725= 117.15374513859981591194584103639
To the nearest whole number: 117
To the nearest tenth: 117.2
Hope this helps!
do you need to include the wiggle infront of the first bracket? if not;
(x+1) ÷ [(x^2+2) x (2x-3dx)]
x^2 x 2x = 2x^3
x^2 x -3dx = -3dx^3
2 x 2x = 4x
2 x -3dx = - 6dx
i cant find a way to make it equal 0 so i think the answer is just
x+1 over 2x^3 - 3dx^3 + 4x - 6dx as a fraction
